Fw: howto use chroot + sshd
|
|
Hi everybody.
I got a problem here.
I want to use chroot + sshd service.
env:
RHEL 5.2
tail -1 /etc/pam.d/sshd
session required pam_chroot.so debug
tail /etc/security/chroot.conf
terry /users
ssh terry [at] 192 faile
tail /var/log/secure
Jun 7 05:05:40 node1 sshd[5397]: pam_chroot(sshd:session): chroot(/users) succeeded <- chroot /users succeeded
Jun 6 21:05:40 node1 sshd[5397]: pam_unix(sshd:session): session closed for user terry
Jun 6 21:05:40 node1 sshd[5399]: pam_env(sshd:setcred): Unable to open config file: /etc/security/pam_env.conf: No such file or directory
Jun 6 21:05:40 node1 sshd[5397]: syslogin_perform_logout: logout() returned an error
Jun 6 21:05:40 node1 sshd[5397]: fatal: openpty returns device for which ttyname fails. <- but why can not get one tty shell ?
Jun 6 21:05:40 node1 sshd[5397]: error: chown 0 0 failed: No such file or directory
Jun 6 21:05:40 node1 sshd[5397]: error: chmod 0666 failed: No such file or directory
ls -l /users/dev/
total 0
srw-rw-rw- 1 terry root 0 Jun 7 04:56 log
crw-rw-rw- 1 terry root 1, 3 Jun 7 04:04 null
crw-rw-rw- 1 terry root 5, 2 Jun 7 04:58 ptmx
drwxrwxrwx 2 terry terry 0 Jun 7 04:55 pts
crw-rw-rw- 1 terry root 5, 0 Jun 7 04:31 tty
crw-r--r-- 1 terry root 1, 9 Jun 7 04:31 urandom
crw-rw-rw- 1 terry root 1, 12 Jun 7 04:31 zero
ls -l /user/dev/pts <- empty
mount
devpts on /users/dev/pts type devpts (rw,uid=500,gid=5,mode=666)
but use command " ssh terry [at] 192 bash -i " I can log into system . .but something wrong , scp command means unknow user 500.
please give me advances.
thank you very much.
Best Regards
Terry Tsang.
