Hi everyone,
We just bumped into the following issue at work.
All of a sudden we could not start new ssh sessions to a RHEL 5.7 server, but existing ones were kept alive.
In those circumstances, these existing connections appeared to be handled by init (as the ssh daemon seemed to be down - it was not showing anymore in the list of running processes, invoked wither with
top or
ps -ef) as shown in the PPID of the following process list:
Code:
me@rhel /home/me:ps -ef | grep ssh | grep -v grep
root 6238 1 0 06:28 ? 00:00:00 sshd: user1@pts/12
root 6847 1 0 08:03 ? 00:00:00 sshd: tn2204@pts/36,pts/37
root 6956 1 0 08:41 ? 00:00:00 sshd: user2@pts/38
root 9271 1 0 06:11 ? 00:00:00 sshd: user3@pts/31
root 9910 1 0 10:17 ? 00:00:00 sshd: user4@pts/25
root 14453 1 0 07:30 ? 00:00:00 sshd: user5@pts/33
root 19932 1 0 10:23 ? 00:00:00 sshd: user6@pts/23
root 20997 1 0 10:23 ? 00:00:00 sshd: user6@pts/29
root 22245 1 0 07:35 ? 00:00:00 sshd: user7@pts/34
root 22920 1 0 Jan07 ? 00:00:00 sshd: user8@pts/24
root 27904 1 0 02:59 ? 00:00:00 sshd: user9@pts/19
root 28148 1 0 Jan02 ? 00:00:00 sshd: user10@pts/27,pts/17
root 29046 1 0 06:23 ? 00:00:00 sshd: user11@pts/5
root 30131 1 0 09:32 ? 00:00:00 sshd: user12@pts/18,pts/39
me@rhel /home/me:
Any ideas why the same process opened 2 terminals for user10 and user12 but user6 had to start 2 processes in order to open 2 terminals?
The version of OpenSSH is
OpenSSH_5.5p1.
Any hints or ideas of what could have caused this issue will be more than appreciated.
