Hello,

the command

which passwd

should return

/usr/bin/passwd

it's probably you are missing passwd binary on your server, probably due to a server has been hacked. You might try using openssl or generate password somewhere else and then copy it to your CentOS 5 server.


By the way CentOS 5.x is EOL you will hardly find RPM packages for it in official repos, and Directadmin will stop supporting it on March 2018, so you are highly encouraged to migrate to CentOS 6, 7 or other actual supported OS.

If you have another CentOS 5 then try and upload the binary.
