 Posted: Mon Oct 03, 2005 12:26 pm Post subject: crontab can't read libc.so.6 [Solved] |
 |
|
Hi,
I have a fresh gentoo server, and when I wanted to run crontab -l (I use sys-process/fcron-2.0.2),
I get this error message:
crontab: error while loading shared libraries: libc.so.6: cannot open shared object file: Permission denied
and if I "strace" it (strace crontab -l) I get following output:
| Code: |
execve("/usr/bin/crontab", ["crontab", "-l"], [/* 42 vars */]) = 0
uname({sys="Linux", node="linux-ha13", ...}) = 0
brk(0) = 0x8000d000
fcntl64(0, F_GETFD) = 0
fcntl64(1, F_GETFD) = 0
fcntl64(2, F_GETFD) = 0
access("/etc/suid-debug", F_OK) = -1 ENOENT (No such file or directory)
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)
open("/etc/ld.so.cache", O_RDONLY) = -1 EACCES (Permission denied)
open("/lib/tls/i686/sse2/libc.so.6", O_RDONLY) = -1 EACCES (Permission denied)
stat64("/lib/tls/i686/sse2", 0xbfc92b70) = -1 EACCES (Permission denied)
open("/lib/tls/i686/libc.so.6", O_RDONLY) = -1 EACCES (Permission denied)
stat64("/lib/tls/i686", 0xbfc92b70) = -1 EACCES (Permission denied)
....

It seems that crontab can't read /etc/ld.so.cache because of the missing permission.
this is my fcrontab:
#ls -l /usr/bin/fcrontab
---s--s--- 1 cron cron 47292 Oct 3 13:00 /usr/bin/fcrontab
and
#ls -l /etc/ld.so.cache
-rw-r--r-- 1 root root 59994 Oct 3 13:14 /etc/ld.so.cache
So, what do I forget here?
thanks,
Simba.

Hi,
I've got nearly the same problem.
I've also a fresh gentoo server with fcron-3.0.0. I started the install on September, 30th.
I get this error message while working as root ('crontab' seems to work for ordinary users.):
| Code: |
crontab: error while loading shared libraries: libpam.so.0: cannot open shared object file: Permission denied
|
Here's the output of 'strace crontab -l'
| Code: |
router2 cron # strace crontab -l
execve("/usr/bin/crontab", ["crontab", "-l"], [/* 31 vars */]) = 0
uname({sys="Linux", node="router2", ...}) = 0

When I change the permission of fcrontab from '---s--s---' to something like '-rwxr-xr-x' or '-rwsr-sr-x' the error messages changes to:
| Code: |
15:00:18 Could not chdir to /var/spool/cron/fcrontabs: Permission denied
|
Any suggestions ? Thanks.
ciao,
christoph |

| Posted: Mon Oct 03, 2005 4:06 pm Post subject: strange permission in root directory |
|
|
I found out that the permission of root directory is
d-wxr----t 17 root root 4096 Sep 14 17:00 /
and this is not only in 1 fresh server, but also in 2 other fresh servers.
it is somehow strange, because normally it is like
drwxr-xr-x 19 root root 4096 Jan 30 2004 /
so, after I chmod root directory to drwxr-xr-x, crontab works as properly.
Is the persmission d-wxr----t new in gentoo? or is it a bug of installation process?
thanks,
Simba |

Moved from Installing Gentoo to Other Things Gentoo.
Post installation problem, so better off here.

Try looking at "http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=5", find the red box half way down the page. This has been covered many times I believe

The solution is indeed

Actually, I solve this fcron problem little differently: | Code: | | # chgrp fcron /var/spool/cron |
.
It was root:cron, and it supposed to be root:fcron, if you switch from vixie-cron to fcron.

Thanks, jsosic, that was my problem as well. Any idea why the permissions had changed lately? |

Well I don't understand it either why maintainer of fcron package didn't use cron user but switched to fcron... Maybe because fcron works completely differently than cron, so you don't mix up each other's directories? But then why didn't he chgrp with ebuild's postinstall?!
