Title: SSH won't start (prob after sme 7.0 to 7.1 update)
Post by: Dirk on February 04, 2007, 10:58:18 AM

All of a sudden ssh stopped working after a post-upgrade and reboot.

sshd logfile shows:

/etc/ssh/sshd_config: line 21: Bad configuration option: UsePAM
/etc/ssh/sshd_config: line 30: Bad configuration option: MaxAuthTries
/etc/ssh/sshd_config: terminating, 2 bad configuration options

sshd_config:

If i comment out those 2 configuration options Usepam and maxauthtries sshd starts and works normally!

On my system are the following rpm's for ssh:

e-smith-openssh-1.12.0-6.el4.sme.noarch.rpm
openssh-3.9p1-8.RHEL4.17.1.i386.rpm
openssh-clients-3.9p1-8.RHEL4.17.1.i386.rpm
openssh-server-3.9p1-8.RHEL4.17.1.i386.rpm

btw my system is running at the first kernel of 7.0 cause the other kernels won't boot/mount my scsi mirror raid (lvm errors)

config show sshd:

sshd=service
    MaxAuthTries=2
    PasswordAuthentication=yes
    PermitRootLogin=yes
    Protocol=2
    TCPPort=22
    access=private
    status=enabled

Does anybody know whats wrong?

Same problem here.

When i try service sshd start it responds with OK but i can't connect using Putty or WINscp3.

Did you solve the problem yet?
