ssh to a FC5 test1 system fails, fails to create pts device nodes with 2.6.14-1.1783

[Kevin Verma]

Hello,

I updated the kernel to kernel-2.6.14-1.1783_FC5 on a FC5 test1
machine, and after reboot I could not log on to it via ssh, the error
message in log files were as following:
(hand typed)

tailf -f /var/log/secure
sshd (pid): Accepted public key for root from 192.168.0.3
sshd (pid): pam_unix(sshd:session): session opened for user root by (uid=0)
sshd (pid): error: openpty: no such file or directory
sshd (pid): session_pty_req: session 0 alloc failed

Looking into /dev/pts/ , there are zero files.

I'll like to know if this report has got attention of the kernel
package developers and to suggest an intermediate fix.

Cheers,

[Arjan van de Ven]

this most likely is an initscripts issue; /dev/pts needs to be mounted..
and from the sound of what you have... it's not.

Hello Arjan,

You are right it is same situation with the older kernel as I just
rebooted to that. However /dev/pts is mounted already

/dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620)

Done the update of initscripts but same problem, I'll update my
investigation here soon.

Cheers,

and remember to file a bug report post investigation.

Sure will file bug reports when done, meanwhile some of the logs
messeges I am pasting here:

Dec 25 11:48:35 server1 udevinfo[1874]: udev_db_get_all_entries:
unable to open udev_db '/dev/.udev/db': No such file or dir
ectory

Oh is that the problem caused by recent udev update "udev-078-2" ; Yes
and got fixed when I removed the udev update and made a fall back to
original "udev-075-4"

So the system booted fine and I could log in via ssh and no error
messages that caught my extreme focus exept "kudzu" which had a
segfault while kudzu startup.

Thanks to all please continue this thread if you find anything related.

Cheers,
