ssh_keygen- user@hostname vs. user@IPAddress ?


I'm running sftp from machine alpha. Machine alpha's "authorized_keys" file contains machine beta's public key. Machine beta's public key has user@hostname.domainname embedded at the end. Machine alpha only recognizes machine beta as it's IP Address, not by it's hostname.

Running sftp from alpha using user@nnn.nnn.nnn.nnn works, whereas user@hostname and user@hostname.domainname don't. So, I can do scripted gets logged on beta from alpha, but cannot do scripted puts logged on alpha to beta.

Is there a way to get ssh_keygen to generate a key that has user@IPAddress embedded in it rather than user@hostname.domainname ? Or, is there another alternative to this hostname/IPAddress public key mismatch ?

Your prompt cooperation is greatly appreciated, Neil

Two things to try:

1) put "nnn.nnn.nnn.nnn hostname.domainname" in your /etc/hosts file on alpha.

2) change user@hostname.domainname to user@nnn.nnn.nnn.nnn in your authorized_keys file.




domain, embedded, ssh public key, user
