I have a quick question on editing the sshd_config file in RedHat. What I'm trying to do is add the ciphers option in the sshd_config by adding the following line: Ciphers aes128-ctr,aes192-ctr,aes256-ctr
Pardon my ignorance here, I'm rather new to the Linux world. When editing the sshd_config file, I assume that I can add that line anywhere within the sshd_config file? Once I've added that line, is there a particular command needed to save my work?
Basically, what I'm doing now to "attempt" this is this: I'll log in as Root, then will do a: # vim /etc/ssh/sshd_config it will open and ask me if I want to Open, Delete, Edit, etc the file. I choose "E" for Edit, then I went in and added the line: Ciphers aes128-ctr,aes192-ctr,aes256-ctr at the very bottom of the config file, then will click the X to close out of the session, thinking it would save my changes. When I try and go back into the sshd_config file, it's telling me that it's detected a SWP file and I cannot see the line: Ciphers aes128-ctr,aes192-ctr,aes256-ctr that I added to it, it's reverting back. Thank you in advance for your help!
