I have written an expect script to automate the login process for ssh. My user account has rsa keys setup but once I log in I want to switch to root but the remote server is hanging on the password. I can see the script feeding the password to the remote server, albeit its visible, which is another thing I'd like to know if I can hide. But can someone tell me why this is hanging?
#!/usr/bin/expect spawn ssh <server> su - expect "Password" send "MyPassword\r" interact
It just sits there at this screen:
With the cursor right below it which blinks continously. In /var/log/secure I have compared the lines of my scripted login attempt with a normal one where I manually get root.
Jun 7 15:17:50 <server> su: pam_unix(su-l:session): session opened for user root by (uid=1000)
Jun 7 15:18:48 <server> su: pam_unix(su-l:session): session opened for user root by <user>(uid=1000)
The only thing is that I see different is the manual login has my username listed.
I have tried changing up the command to :
spawn ssh <server> su - root spawn ssh <server> sudo su
But neither one works. How can I get this going?
