1.20 millert 1: Installation instructions for Sudo 1.7
2: ======================================
1.1 millert 3:
4: Sudo uses a `configure' script to probe the capabilities and type
5: of the system in question. In this release, `configure' takes many
6: more options than it did before. Please read this document fully
7: before configuring and building sudo. You may also wish to read the
8: file INSTALL.configure which explains more about the `configure' script.
9:
10: Simple sudo installation
11: ========================
12:
13: For most systems and configurations it is possible simply to:
14:
15: 0) If you are upgrading from a previous version of sudo
16: please read the info in the UPGRADE file before proceeding.
17:
18: 1) If you previously ran `configure' on a different host
19: you will probably want to do a `make distclean' to remove
20: the old `config.cache' file. Otherwise, `configure'
21: will complain and refuse to run. Alternately, one can
22: simply `rm config.cache'.
23:
24: 2) Read the `OS dependent notes' section for any particular
25: "gotchas" relating to your operating system.
26:
27: 3) `cd' to the source or build directory and type `./configure'
28: to generate a Makefile and config.h file suitable for
29: building sudo. Before you actually run configure you
30: should read the `Available configure options' section
31: to see if there are any special options you may want
1.7 millert 32: or need.
1.1 millert 33:
34: 4) Edit the configure-generated Makefile if you wish to
1.16 millert 35: change any of the default paths (alternatively, you could
1.1 millert 36: have changed the paths via options to `configure'.
37:
38: 5) Type `make' to compile sudo. If you are building sudo
39: in a separate build tree (apart from the sudo source)
40: GNU make will probably be required. If `configure' did
41: its job properly (and you have a supported configuration)
42: there won't be any problems. If this doesn't work, take
43: a look at the files TROUBLESHOOTING and PORTING for tips
44: on what might have gone wrong. Please mail us if you have a
45: fix or if you are unable to come up with a fix (address at EOF).
46:
47: 6) Type `make install' (as root) to install sudo, visudo, the
48: man pages, and a skeleton sudoers file. Note that the install
49: will not overwrite an existing sudoers file. You can also
50: install various pieces the package via the install-binaries,
51: install-man, and install-sudoers make targets.
52:
53: 7) Edit the sudoers file with `visudo' as necessary for your
54: site. You will probably want to refer the sample.sudoers
55: file and sudoers man page included with the sudo package.
56:
57: 8) If you want to use syslogd(8) to do the logging, you'll need
58: to update your /etc/syslog.conf file. See the sample.syslog.conf
59: file included in the distribution for an example.
60:

127:
128: --with-blibpath[=PATH]
1.16 millert 129: Tells configure to construct a -blibpath argument to the
130: loader. If a PATH is specified, it will be used as the
131: base. Otherwise, "/usr/lib:/lib:/usr/local/lib" will be

163: (or at least the library and header files).
164:
1.14 millert 165: --with-kerb4[=DIR]
1.16 millert 166: Enable Kerberos IV support. If specified, DIR is the base
167: directory containing the Kerberos IV include and lib dirs.
168: This uses Kerberos passphrases for authentication but does
169: not use the Kerberos cookie scheme.
1.14 millert 170:
171: --with-kerb5[=DIR]
1.16 millert 172: Enable Kerberos V support. If specified, DIR is the base
173: directory containing the Kerberos V include and lib dirs.
174: This This uses Kerberos passphrases for authentication but
175: does not use the Kerberos cookie scheme. Will not work for
176: Kerberos V older than version 1.1.
1.1 millert 177:
1.15 millert 178: --with-ldap[=DIR]
179: Enable LDAP support. If specified, DIR is the base directory
180: containing the LDAP include and lib directories. Please see
181: README.LDAP for more information.
182:
1.16 millert 183: --with-ldap-conf-file=filename

186:
1.16 millert 187: --with-ldap-secret-file=filename
188: Path to LDAP secret password file. If specified, sudo uses
189: this file instead of /etc/ldap.secret to read the secret password
190: when rootbinddn is specified in the ldap config file.
191:
1.20 millert 192: --with-nsswitch[=filename]
193: Path to nsswitch.conf or "no" to disable nsswitch support.
194: If specified, sudo uses this file instead of /etc/nsswitch.conf.
195: If nsswitch is disabled but LDAP is enabled, sudo will check
196: LDAP first, then the sudoers file.
197:
1.21 millert 198: --with-netsvc[=filename]
199: Path to netsvc.conf or "no" to disable netsvc.conf support.
200: If specified, sudo uses this file instead of /etc/netsvc.conf
201: on AIX systems.
202:
1.16 millert 203: --with-aixauth
1.1 millert 204: Enable support for the AIX 4.x general authentication function.
205: This will use the authentication scheme specified for the user
1.16 millert 206: on the machine. It is on by default for AIX systems that
207: support it.
1.1 millert 208:
209: --with-pam
1.16 millert 210: Enable PAM support. This is on by default for Darwin, FreeBSD,
211: Linux, Solaris and HP-UX (version 11 and higher).
212:
213: NOTE: on RedHat Linux and Fedora you *must* have an /etc/pam.d/sudo
1.20 millert 214: file install. You may either use the sample.pam file included with
1.15 millert 215: sudo or use /etc/pam.d/su as a reference. The sample.pam file
216: included with sudo may or may not work with other Linux distributions.
217: On Solaris and HP-UX 11 systems you should check (and understand)
218: the contents of /etc/pam.conf. Do a "man pam.conf" for more
219: information and consider using the "debug" option, if available,
220: with your PAM libraries in /etc/pam.conf to obtain syslog output
221: for debugging purposes.
1.1 millert 222:
223: --with-AFS
1.13 millert 224: Enable AFS support with Kerberos authentication. Should work under
1.1 millert 225: AFS 3.3. If your AFS doesn't have -laudit you should be able to
226: link without it.
227:
228: --with-DCE
1.15 millert 229: Enable DCE support for systems without PAM. Known to work on
230: HP-UX 9.X, 10.X, and 11.0; other systems may require source
231: code and/or `configure' changes. On systems with PAM support
232: (such as HP-UX 11.0 and higher, Solaris, FreeBSD and Linux), the
233: DCE PAM module (usually libpam_dce) should be used instead.
1.1 millert 234:
1.5 millert 235: --with-logincap
1.16 millert 236: This adds support for login classes specified in /etc/login.conf.
237: It is enabled by default on BSD/OS, Darwin, FreeBSD, OpenBSD and
238: NetBSD (where available). By default, a login class is not applied
239: unless the 'use_loginclass' option is defined in sudoers or the user
240: specifies a class on the command line.
241:
1.6 millert 242: --with-bsdauth
1.16 millert 243: Enable support for BSD authentication. This is the default
244: for BSD/OS and OpenBSD systems that support it.
245: It is not possible to mix BSD authentication with other
246: authentication methods (and there really should be no need
247: to do so). Note that only the newer BSD authentication API
248: is supported. If you don't have /usr/include/bsd_auth.h
249: then you cannot use this.
1.10 millert 250:
1.20 millert 251: --with-project
252: Enable support for Solaris project resource limits.
253: This option is only available on Solaris 9 and above.
254:
1.15 millert 255: --with-noexec[=PATH]
1.16 millert 256: Enable support for the "noexec" functionality which prevents
257: a dynamically-linked program being run by sudo from executing
258: another program (think shell escapes). Please see the
259: "PREVENTING SHELL ESCAPES" section in the sudoers man page
260: for details. If specified, PATH should be a fully qualified
261: pathname, e.g. /usr/local/libexec/sudo_noexec.so. If PATH
262: is "no", noexec support will not be compiled in. The default
263: is to compile noexec support if libtool supports building
264: shared objects on your OS.
1.15 millert 265:
1.18 millert 266: --disable-pam-session
267: Disable sudo's PAM session support. This may be needed on
268: older PAM implementations or on operating systems where
269: opening a PAM session changes the utmp or wtmp files. If
270: PAM session support is disabled, resource limits may not
271: be updatedin for command being run.
272:
1.10 millert 273: --disable-root-mailer
1.16 millert 274: By default sudo will run the mailer as root when tattling
275: on a user so as to prevent that user from killing the mailer.
276: With this option, sudo will run the mailer as the invoking
277: user which some people consider to be safer.
1.11 millert 278:
279: --disable-setreuid
1.16 millert 280: Disable use of the setreuid() function for operating systems
281: where it is broken. Mac OS X has setreuid() but it doesn't
282: really work.
1.5 millert 283:
1.13 millert 284: --disable-setresuid
1.16 millert 285: Disable use of the setresuid() function for operating systems
286: where it is broken (none currently known).
1.13 millert 287:
1.1 millert 288: --disable-sia
1.16 millert 289: Disable SIA support. This is the "Security Integration
290: Architecture" on Digital UNIX. If you disable SIA sudo will
291: use its own authentication routines.
1.1 millert 292:
293: --disable-shadow
1.16 millert 294: Disable shadow password support. Normally, sudo will compile
295: in shadow password support and use a shadow password if it
296: exists.
1.12 millert 297:
298: --with-sudoers-mode=MODE
1.16 millert 299: File mode for the sudoers file (octal). Note that if you
300: wish to NFS-mount the sudoers file this must be group
301: readable. Also note that this is actually set in the
302: Makefile. The default mode is 0440.
1.12 millert 303:
304: --with-sudoers-uid=UID
1.16 millert 305: User id that "owns" the sudoers file. Note that this is
306: the numeric id, *not* the symbolic name. Also note that
307: this is actually set in the Makefile. The default is 0.
1.12 millert 308:
309: --with-sudoers-gid=GID
1.16 millert 310: Group id that "owns" the sudoers file. Note that this is
311: the numeric id, *not* the symbolic name. Also note that
312: this is actually set in the Makefile. The default is 0.
1.1 millert 313:
314: --without-interfaces
1.16 millert 315: This option keeps sudo from trying to glean the ip address
316: from each attached ethernet interface. It is only useful
317: on a machine where sudo's interface reading support does
318: not work, which may be the case on some SysV-based OS's
319: using STREAMS.
1.1 millert 320:
321: --without-passwd
1.16 millert 322: This option excludes authentication via the passwd (or
323: shadow) file. It should only be used when another, alternative,
324: authentication scheme is in use.
1.1 millert 325:
326: --with-otp-only
1.16 millert 327: This option is now just an alias for --without-passwd.
1.13 millert 328:
329: --with-stow
1.16 millert 330: Properly handle GNU stow packaging. The sudoers file will
331: physically live in ${prefix}/etc and /etc/sudoers will be
332: a symbolic link.
1.1 millert 333:
1.19 millert 334: --with-selinux
335: Enable support for role based access control (RBAC) on
336: systems that support SELinux.
337:
1.22 ! millert 338: --with-libvas=[NAME]
! 339: Enable non-Unix group support using Quest Authentication
! 340: Services. If NAME is specified, it should be the name of
! 341: the shared library providing QAS support (libvas.so by default).
! 342:
! 343: --with-libvas-rpath=[PATH]
! 344: The path to search when loading libvas.so (or an alternate
! 345: name as specified by --with-libvas). This option only has
! 346: an effect when --with-libvas is specified.
! 347:
1.4 millert 348: The following options are also configurable at runtime:
349:
1.1 millert 350: --with-long-otp-prompt
1.16 millert 351: When validating with a One Time Password scheme (S/Key or
352: OPIE), a two-line prompt is used to make it easier to cut
353: and paste the challenge to a local window. It's not as
354: pretty as the default but some people find it more convenient.
1.1 millert 355:
356: --with-logging=TYPE
1.16 millert 357: How you want to do your logging. You may choose "syslog",
358: "file", or "both". Setting this to "syslog" is nice because
359: you can keep all of your sudo logs in one place (see the
360: sample.syslog.conf file). The default is "syslog".
1.1 millert 361:
362: --with-logfac=FACILITY
1.16 millert 363: Determines which syslog facility to log to. This requires
364: a 4.3BSD or later version of syslog. You can still set
365: this for ancient syslogs but it will have no effect. The
366: following facilities are supported: authpriv (if your OS
367: supports it), auth, daemon, user, local0, local1, local2,
368: local3, local4, local5, local6, and local7.
1.1 millert 369:
370: --with-goodpri=PRIORITY
1.16 millert 371: Determines which syslog priority to log successfully
372: authenticated commands. The following priorities are
373: supported: alert, crit, debug, emerg, err, info, notice,
374: and warning.
1.1 millert 375:
376: --with-badpri=PRIORITY
1.16 millert 377: Determines which syslog priority to log unauthenticated
378: commands and errors. The following priorities are supported:
379: alert, crit, debug, emerg, err, info, notice, and warning.
1.12 millert 380:
381: --with-logpath=PATH
1.16 millert 382: Override the default location of the sudo log file and use
383: "path" instead. By default will use /var/log/sudo.log if
384: there is a /var/log dir, falling back to /var/adm/sudo.log
385: or /usr/adm/sudo.log if not.
1.1 millert 386:
1.12 millert 387: --with-loglen=NUMBER
1.1 millert 388: Number of characters per line for the file log. This is only used if
389: you are to "file" or "both". This value is used to decide when to wrap
390: lines for nicer log files. The default is 80. Setting this to 0
391: will disable the wrapping.
392:
393: --with-ignore-dot
394: If set, sudo will ignore '.' or '' (current dir) in $PATH.
395: The $PATH itself is not modified.
396:
1.12 millert 397: --with-mailto=USER|MAIL_ALIAS
398: User (or mail alias) that mail from sudo is sent to.
399: This should go to a sysadmin at your site. The default is "root".
1.1 millert 400:
1.12 millert 401: --with-mailsubject="SUBJECT OF MAIL"
1.1 millert 402: Subject of the mail sent to the "mailto" user. The token "%h"
403: will expand to the hostname of the machine.
404: Default is "*** SECURITY information for %h ***".
405:
406: --without-mail-if-no-user
1.4 millert 407: Normally, sudo will mail to the "alertmail" user if the user invoking
1.1 millert 408: sudo is not in the sudoers file. This option disables that behavior.
409:
410: --with-mail-if-no-host
411: Send mail to the "alermail" user if the user exists in the sudoers
412: file, but is not allowed to run commands on the current host.
413:
414: --with-mail-if-noperms
415: Send mail to the "alermail" user if the user is allowed to use sudo but
416: the command they are trying is not listed in their sudoers file entry.
417:
1.12 millert 418: --with-passprompt="PASSWORD PROMPT"
1.1 millert 419: Default prompt to use when asking for a password; can be overridden
420: via the -p option and the SUDO_PROMPT environment variable. Supports
1.17 millert 421: the "%H", "%h", "%U" and "%u" escapes as documented in the sudo
422: manual page. The default value is "Password:".
1.1 millert 423:
1.12 millert 424: --with-badpass-message="BAD PASSWORD MESSAGE"
1.1 millert 425: Message that is displayed if a user enters an incorrect password.
426: The default is "Sorry, try again." unless insults are turned on.
427:
428: --with-fqdn
1.16 millert 429: Define this if you want to put fully qualified hostnames in the sudoers
1.1 millert 430: file. Ie: instead of myhost you would use myhost.mydomain.edu. You may
431: still use the short form if you wish (and even mix the two). Beware
432: that turning FQDN on requires sudo to make DNS lookups which may make
433: sudo unusable if your DNS is totally hosed. Also note that you must
434: use the host's official name as DNS knows it. That is, you may not use
435: a host alias (CNAME entry) due to performance issues and the fact that
436: there is no way to get all aliases from DNS.
437:
1.12 millert 438: --with-timedir=PATH
1.1 millert 439: Override the default location of the sudo timestamp directory and
440: use "path" instead.

448:
1.12 millert 449: --with-umask=MASK
1.1 millert 450: Umask to use when running the root command. The default is 0022.
451:
452: --without-umask
453: Preserves the umask of the user invoking sudo.
454:
1.12 millert 455: --with-runas-default=USER
1.1 millert 456: The default user to run commands as if the -u flag is not specified
457: on the command line. This defaults to "root".
458:
1.12 millert 459: --with-exempt=GROUP
1.1 millert 460: Users in the specified group don't need to enter a password when
461: running sudo. This may be useful for sites that don't want their
462: "core" sysadmins to have to enter a password but where Jr. sysadmins
463: need to. You should probably use NOPASSWD in sudoers instead.
464:
1.12 millert 465: --with-passwd-tries=NUMBER
1.1 millert 466: Number of tries a user gets to enter his/her password before sudo logs
467: the failure and exits. The default is 3.
468:
1.12 millert 469: --with-timeout=NUMBER
1.1 millert 470: Number of minutes that can elapse before sudo will ask for a passwd
471: again. The default is 5, set this to 0 to always prompt for a password.
472:
1.12 millert 473: --with-password-timeout=NUMBER
1.1 millert 474: Number of minutes before the sudo password prompt times out.
475: The default is 5, set this to 0 for no password timeout.
476:
477: --with-tty-tickets
1.4 millert 478: This makes sudo use a different ticket file for each user/tty combo.
479: Ie: instead of the ticket path being "username" it is "username/tty".
1.1 millert 480: This is useful for "shared" accounts like "operator". Note that this
481: means that there will be more files in the timestamp dir. This is not
482: a problem if your system has a cron job to remove of files from /tmp
483: (or wherever you specified the timestamp dir to be).
484:
485: --with-insults
486: Define this if you want to be insulted for typing an incorrect password
487: just like the original sudo(8). This is off by default.
488:
489: --with-all-insults
1.7 millert 490: Include all the insult sets listed below. You must either specify
491: --with-insults or enable insults in the sudoers file for this to
492: have any effect.
1.1 millert 493:
494: --with-classic-insults
495: Uses insults from sudo "classic." If you just specify --with-insults
496: you will get the classic and CSOps insults. This is on by default if
497: --with-insults is given.
498:
499: --with-csops-insults
500: Insults the user with an extra set of insults (some quotes, some
501: original) from a sysadmin group at CU (CSOps). You must specify
502: --with-insults as well for this to have any effect. This is on by
503: default if --with-insults is given.
504:
505: --with-hal-insults
506: Uses 2001-like insults when an incorrect password is entered.
1.7 millert 507: You must either specify --with-insults or enable insults in the
508: sudoers file for this to have any effect.
1.1 millert 509:
510: --with-goons-insults
511: Insults the user with lines from the "Goon Show" when an incorrect
1.7 millert 512: password is entered. You must either specify --with-insults or
513: enable insults in the sudoers file for this to have any effect.
1.1 millert 514:
1.15 millert 515: --with-pc-insults
516: Replace politically incorrect insults with less objectionable ones.
517:
1.12 millert 518: --with-secure-path[=PATH]
1.1 millert 519: Path used for every command run from sudo(8). If you don't trust the
520: people running sudo to have a sane PATH environment variable you may
521: want to use this. Another use is if you want to have the "root path"
522: be separate from the "user path." You will need to customize the path
523: for your site. NOTE: this is not applied to users in the group
524: specified by --with-exemptgroup. If you do not specify a path,
525: "/bin:/usr/ucb:/usr/bin:/usr/sbin:/sbin:/usr/etc:/etc" is used.
526:
527: --without-lecture
528: Don't print the lecture the first time a user runs sudo.
529:
1.12 millert 530: --with-editor=PATH
1.15 millert 531: Specify the default editor path for use by visudo. This may be a
532: single pathname or a colon-separated list of editors. In the latter
533: case, visudo will choose the editor that matches the user's VISUAL
534: or EDITOR environment variables or the first editor in the list that
535: exists. The default is the path to vi on your system.
1.5 millert 536:
537: --with-env-editor
1.15 millert 538: Makes visudo consult the VISUAL and EDITOR environment variables before
1.7 millert 539: falling back on the default editor list (as specified by --with-editor).
540: Note that this may create a security hole as it allows the user to
541: run any arbitrary command as root without logging. A safer alternative
1.15 millert 542: is to use a colon-separated list of editors with the --with-editor
543: option. visudo will then only use the VISUAL or EDITOR variables
544: if they match a value specified via --with-editor.
1.5 millert 545:
1.20 millert 546: --with-askpass=PATH
547: Set PATH as the "askpass" program to use when no tty is
548: available. Typically, this is a graphical password prompter,
549: similar to the one used by ssh. The program must take a
550: prompt as an argument and print the received password to
551: the standard output.
552:
1.1 millert 553: --disable-authentication
1.16 millert 554: By default, sudo requires the user to authenticate via a
555: password or similar means. This options causes sudo to
556: *not* require authentication. It is possible to turn
557: authentication back on in sudoers via the PASSWD attribute.
1.1 millert 558:
559: --disable-root-sudo
560: Don't let root run sudo. This can be used to prevent people from
561: "chaining" sudo commands to get a root shell by doing something
562: like "sudo sudo /bin/sh".
563:
1.20 millert 564: --enable-gss-krb5-ccache-name
565: Use the gss_krb5_ccache_name() function to set the Kerberos
566: V credential cache file name. By default, sudo will use
567: the KRB5CCNAME environment variable to set this. While
568: gss_krb5_ccache_name() provides a better API to do this it
569: is not supported by all Kerberos V and SASL combinations.
570:
1.1 millert 571: --enable-log-host
572: Log the hostname in the log file.
1.3 millert 573:
574: --enable-noargs-shell
575: If sudo is invoked with no arguments it acts as if the "-s" flag had
576: been given. That is, it runs a shell as root (the shell is determined
577: by the SHELL environment variable, falling back on the shell listed
578: in the invoking user's /etc/passwd entry).
1.1 millert 579:
580: --enable-shell-sets-home
581: If sudo is invoked with the "-s" flag the HOME environment variable
582: will be set to the home directory of the target user (which is root
583: unless the "-u" option is used). This option effectively makes the
584: "-s" flag imply "-H".
585:
586: --disable-path-info
587: Normally, sudo will tell the user when a command could not be found
588: in their $PATH. Some sites may wish to disable this as it could
589: be used to gather information on the location of executables that
590: the normal user does not have access to. The disadvantage is that
591: if the executable is simply not in the user's path, sudo will tell
592: the user that they are not allowed to run it, which can be confusing.
593:
594: Shadow password and C2 support
595: ==============================
596:
597: Shadow passwords (also included with most C2 security packages) are
598: supported on most major platforms for which they exist. The
599: `configure' script will attempt to determine if your system can use
600: shadow passwords and include support for them if so. Shadow password
601: support is now compiled in by default (it doesn't hurt anything if you
602: don't have them configured). To disable the shadow password support,
603: use the --disable-shadow option to configure.
604:
605: Shadow passwords are known to work on the following platforms:
606:
607: SunOS 4.x
608: Solaris 2.x
609: HP-UX >= 9.x
610: Ultrix 4.x
611: Digital UNIX
612: IRIX >= 5.x
613: AIX >= 3.2.x
614: ConvexOS with C2 security (not tested recently)
615: Linux
616: SCO >= 3.2.2
617: Pyramid DC/OSx
618: UnixWare
619: SVR4 (and variants using standard SVR4 shadow passwords)
620: 4.4BSD based systems (including OpenBSD, NetBSD, FreeBSD, and BSD/OS)
621: OS's using SecureWare's C2 security.
622:
623: OS dependent notes
624: ==================
625:
626: OpenBSD < 2.2 and NetBSD < 1.2.1:
1.15 millert 627: The fdesc file system has a bug wrt /dev/tty handling that
1.1 millert 628: causes sudo to hang at the password prompt. The workaround
629: is to run configure with --with-password-timeout=0
630:
631: Solaris 2.x:
632: You need to have a C compiler in order to build sudo.
633: Since Solaris 2.x does not come with one by default this
634: means that you either need to have purchased the unbundled Sun
635: C compiler or have a copy of the GNU C compiler (gcc).
636: The SunSoft Catalyst CD should contain gcc binaries for
637: Solaris. You can also get them from various places on the
638: net, including http://www.sunfreeware.com/
639: NOTE: sudo will *not* build with the sun C compiler in BSD
1.16 millert 640: compatibility mode (/usr/ucb/cc). Sudo is designed to
641: compile with the standard C compiler (or gcc) and will
642: not build correctly with /usr/ucb/cc. You can use the
643: `--with-CC' option to point `configure' to the non-ucb
644: compiler if it is not the first cc in your path. Some
645: sites link /usr/ucb/cc to gcc; configure will not notice
646: this an still refuse to use /usr/ucb/cc, so make sure gcc
647: is also in your path if your site is setup this way.
1.1 millert 648: Also: Many versions of Solaris come with a broken syslogd.
649: If you have having problems with sudo logging you should
650: make sure you have the latest syslogd patch installed.
651: This is a problem for Solaris 2.4 and 2.5 at least.
652:
653: AIX 3.2.x:
654: I've had various problems with the AIX C compiler producing
655: incorrect code when the -O flag was used. When optimization
656: is not used, the problems go away. Gcc does not appear
657: to have this problem.
658:
659: Also, the AIX 3.2.x lex will not work with sudo's parse.lex.
660: This should not be a problem as sudo comes shipped with
661: a pre-generated lex.yy.c (created by flex). If you want
662: to modify the lex tokenizer, make sure you grab a copy of
663: flex from ftp.ee.lbl.gov (also available on most GNU mirrors)
664: and sudo will use that instead.
665:
666: Ultrix 4.x:
667: Ultrix still ships with the 4.2BSD syslog(3) which does not
668: allow things like logging different facilities to different
669: files, redirecting logs to a single loghost and other niceties.
670: You may want to just grab and install:
671: ftp://gatekeeper.dec.com/pub/DEC/jtkohl-syslog-complete.tar.Z
672: (available via anonymous ftp) which is a port if the 4.3BSD
673: syslog/syslogd that is backwards compatible with the Ultrix version.
674: I recommend it highly. If you do not do this you probably want
675: to run configure with --with-logging=file
676:
677: Digital UNIX:
678: By default, sudo will use SIA (Security Integration Architecture)
1.16 millert 679: to validate a user. If you want to use an alternative authentication
1.1 millert 680: method that does not go through SIA, you need to use the
681: --disable-sia option to configure. If you use gcc to compile
682: you will get warnings when building interfaces.c. These are
683: harmless but if they really bug you, you can edit
684: /usr/include/net/if.h around line 123, right after the comment:
685: /* forward decls for C++ */
686: change the line:
687: #ifdef __cplusplus
688: to:
689: #if defined(__cplusplus) || defined(__GNUC__)
690: If you don't like the idea of editing the system header file
691: you can just make a copy in gcc's private include tree and
692: edit that.
693:
694: Linux:
1.16 millert 695: PAM and LDAP headers are not installed by default on most Linux
696: systems. You will need to install the "pav-dev" package if
697: /usr/include/security/pam_appl.h is not present on your system.
698: If you wish to build with LDAP support you will also need the
699: openldap-devel package.
700:
1.1 millert 701: Versions of glibc 2.x previous to 2.0.7 have a broken lsearch().
702: You will need to either upgrade to glibc-2.0.7 or use sudo's
703: version of lsearch(). To use sudo's lsearch(), comment out
704: the "#define HAVE_LSEARCH 1" line in config.h and add lsearch.o
705: to the LIBOBJS line in the Makefile.
706:
1.9 millert 707: If you are using a Linux kernel older than 2.4 it is not possible
708: to access the sudoers file via NFS. This is due to a bug in
709: the Linux client-side NFS implementation that has since been
710: fixed. There is a workaround on the sudo ftp site, linux_nfs.patch,
711: if you need to NFS-mount sudoers on older Linux kernels.
1.11 millert 712:
1.1 millert 713: Mac OS X:
714: It has been reported that for sudo to work on Mac OS X it must
715: either be built with the --with-password-timeout=0 option or the
716: password timeout must be disabled in the Defaults line in the
717: sudoers file. If sudo just hangs when you try to enter a password,
718: you need to disable the password timeout (Note: this is not a bug
719: in sudo).
720:
721: SCO ODT:
722: You'll probably need libcrypt_i.a available via anonymous ftp
723: from sosco.sco.com. The necessary files are /SLS/lng225b.Z
724: and /SLS/lng225b.ltr.Z.
1.5 millert 725:
726: Dynix:
727: Some people have experienced problems building sudo with gcc
728: on Dynix. If you experience problems compiling sudo using gcc
729: on Dynix, try using the native compiler (cc). You can do so
730: by removing the config.cache file and then re-running configure
731: with the --with-CC=cc option.
1.15 millert 732:
733: HP-UX:
734: The default C compiler shipped with HP-UX does not support creating
735: position independent code and so is unable to support sudo's "noexec"
736: functionality. You must use either the HP ANSI C compiler or gcc for
737: noexec to work. Binary packages of gcc are available from
738: http://hpux.connect.org.uk/ and http://hpux.cs.utah.edu/.
1.20 millert 739:
740: To prevent PAM from overriding the value of umask on HP-UX 11,
741: you will need to add a line like the following to /etc/pam.conf:
742:
743: sudo session required libpam_hpsec.so.1 bypass_umask
1.16 millert 744:
745: SunOS 4.x:
746: The /bin/sh shipped with SunOS blows up while running configure.
747: You can work around this by installalling bash or zsh. If you
748: have bash or zsh in your path, configure will use it instead
749: automatically.
