How to upgrade ssh on cpanel server

[drew5746]

I tried to upgrade my version of ssh on our cpanel server using the following options ./configure --prefix=/opt --sysconfdir=/etc/ssh in order to match what was already in place and working with cpanel. I finished compiling, installing and restarted sshd through whm. I was able to log in through ssh fine but when i ran ssh -V the old version is still showing up instead of the new on even after restarting sshd. Did I install it in the wrong place? Could someone send me step by step directions to get this upgraded. Thanks in advance!

I'm just wondering why you are manually building SSH and not just using your OS's package manager?

You added --prefix=/opt that will install the ssh in /opt directory. When you run any command like "ssh", the kernel checks for that binary in the current directory and then the paths mentioned in $PATH environmental variable. I believe that you have not added /opt to $PATH variable. So what you can do is add /opt in $PATH variable but before /usr/bin so that the kernel looks for ssh binary in /opt instead of the default installation.

Hi,

You can also try using 'Yum' to get the latest version of SSH installed/upgraded.
Login to SSH as root, backup the existing configuration folder [/etc/ssh/] & execute "yum upgrade openssh*" or "yum install openssh*".
After the process is complete, make sure to restart the SSH service [service sshd restart]

Great advice if they are using a RedHat flavor, but they never mentioned their OS. Zishan is right - make sure all files from the old install are gone before installing to a new location.

I have been using a slightly different configure line over at: http://www.eth0.us/sshd

If you do follow that just make sure you have upgraded to the latest version of both.
