Sftp log issue on RHEL 4

ZAMO · 03-09-2010, 01:24 PM

I have a issue with sftp login for a particular user . When i try to connect using a user zamo am denied with the error
"Login denied"

But the /var/log/message states something as follows:

Code:

Mar  1 08:52:40 Bajdev01 sshd(pam_unix)[19293]: session opened for user zamo by (uid=0)
Mar  1 08:52:40 Bajdev01 modprobe: modprobe: Can't locate module char-major-10-224
Mar  1 08:52:42 Bajdev01 sshd(pam_unix)[19293]: session closed for user zamo

Is this error anything related to kernel module? If so, why its not affecting other users using the same sftp server?

Thanks

"Login denied" alone says nothing. Try running it with "-v -v -v" for verbose messages and check /var/log/{secure,messages} on the sshd side for additional details?

'grep '[[:blank:]]10 char' /usr/src/linux/Documentation/devices.txt' says its a mouse device so I think not. Adding a line "alias char-major-10-224 off" in /etc/modules.conf should suppress the warning.

No idea. You don't list anything that could help solve it. Maybe start by diffing the 'sftp -v -v -v' log of two users, comparing their respective ~/.ssh/ contents and their /var/log/{secure,messages} login details on the sshd side?

I got a different error, for the same user for now .(but I did not changed anything).

Command:	open "zamo@Bajdev01" 22
Command:	Pass: *********
Error:	Authentication failed.
Error:	Critical error

/var/log/secure shows

Code:

/var/log/message shows
