I downloaded the latest version of open ssh since my server was running an older one and i went through all the installation process but for some reason when i issue the command ssh -V the result i get is the older version. Here is my question how can i change this so i know i'm running the new version and not the old one also since is been upgraded i want to get rid off the old one.

Thank You for any help you guys can provide.

How did you install the new version? From a package, or from a source tarball?

More to the point, the source tarball (if you downloaded from www.OpenSSH.org) always installs to the same place, but if the original system came with OpenSSH or had it installed as a package, it could be in a different place. If the old OpenSSH is in a directory that's in your path before the directory where the newly built OpenSSH was installed, that's why you're still getting the old one.

This is why it is generally not advisable to compile software from source. You should use pre-packaged software for your own OS if at all possible. If a new version is not available in package format, then you should change the ./configure arguments to make the prefix for your source build point to the same prefix where the older binaries are installed, that way they will be overwritten.

PS, generally when you install a new version of OpenSSH it also requires a new version of OpenSSL to be built and/or installed as well.

Well the person that was taking care of this server is not here anymore so my guess is that the older version was installed as a package since the server is running red hat 8.
Thank you so much for the quick response also i downloaded from openssh.org as a tarball and i did the ./configure , make and make install
my problem is that i can't find the path that point to the old version i'm sure that the file can be edited so i can change the path to new version so if one of you guys know where to look for this can you please tell me, i came from the windows world but i got tired of it not more wintendo for me hopefully i will never regret steping into the world of linux.

Thank you kindly

$ which sshd
$ which ssh
$ which ssh-keygen
$ which scp
$ which sftp
etc...

I would highly recommend re-installing from package or recompiling with the correct path. It's quite possible that there are a number of scripts on the system that depend on SSH being right where the original installation put it.
