currently I perform operations between different computers in my local network using open SSH; however, when I do this, I always use the computer's IP number to reference the host. (ex: sudo ssh angelo_dev@10.0.0.15)

I'm wondering without yet finding an answer how to do the same thing using (instead of the IP address) the name of the computer ..
Do I have to Installase BIND? And then what else is needed? ...

thanks for every suggestion

Angelo

    Hi!
    
    A quick way to fix that would be to set up a config file under .ssh
    to list username, machine IP and eventually SSH keys and then add a
    nickname for that machine.
    
    I have that in mine:
    
    Host machine_nickname
        Hostname 192.168.0.1
        User fred_onfedora
        IdentityFile ~/.ssh/nickname_rsa
        PubkeyAuthentication yes
    
    
    And then for a machine where I use password (didn't manage to make
    keys work yet and tired of typing the password I use a python scrypt
    which I probably found on stackexchange:
    
!/usr/bin/python                                                                                                                       
    
    from ConfigParser import ConfigParser
    import pexpect
    
    def main():
        url = "" class="moz-txt-link-rfc2396E" href="mailto:fred_onfedora@192.168.0.2">"fred_onfedora@192.168.0.2"
        user, host = url.split('@', 1)
    
        cfg_file = '/home/fred/bin/ssh.cfg'
        cfg = ConfigParser()
        cfg.read(cfg_file)
        passwd = cfg.get(user, host)
    
        child = pexpect.spawn('ssh -p 54 {0}'.format(url))
        child.expect('password:')
        child.sendline(passwd)
        child.interact()
    
    if __name__ == '__main__':
        main()
    
    then as you can guess I have a ssh.cfg file set to 600 containing
    this:
    
    [fred_onfedora]
    192.168.0.1 = mypasswordhasnospace
    
    Both work for me.
    
    Hope this helps you.
    
    Fred
