I have an CentOS 5.5 64-Bit Server which provides an apache, mysql, postfix and so on.
Now i tried to customize sshd-config /etc/ssh/sshd_config a little bit. I want to enable PermitTunnel. But after removing the trailing #, sshd does not start anymore.
sshd starten: /etc/ssh/sshd_config: line 104: Bad configuration option: PermitTunnel
/etc/ssh/sshd_config: terminating, 1 bad configuration options
What can I do to fix this? I have a second webserver with the same os installed and there it works.
sshd-Version (on both servers):
Name : openssh-server
Arch : x86_64
Version : 4.3p2
Release : 41.el5_5.1
Why does sshd not know this option?
