 Posted: Thu Nov 03, 2022 3:32 pm Post subject: netkit-talk on localhost without "@localhost" |
 |
|
Been playing with some classic unix tools lately, and noticed something interesting with netkit-talk.
I've got it set up to only accept from localhost in xinetd.conf. Just testing for now.
I have flags = IPv4 in my xinetd.d/talk config. Wouldn't work with this commented out.
I seem to recall (and the man page states) that once upon a time I could say "talk alice" instead of "talk alice@localhost", to talk with other users on localhost, However, I currently have to say "talk alice@localhost", for it to work. If I say "talk alice", I get:
| Code: |
talk: Two-Spear: No address associated with name
|
Notice that it's using the machine's hostname (Two-Spear), instead of "localhost". This makes me think that talk is preferring the network interface to the internal one in its search order. I suspect there's a keyword I could add to the flags line in the config file to make it default to localhost if I don't pass a machine name, but I can't find any docs which list valid flags.
Any ideas? |

Slippery Jim,
A long time ago I had a shell server that included talk.
It had a static IP and a corresponding entry in /etc/hosts.
That's not such a good idea if your IP address can change.
-- edit --
| Code: | DESCRIPTION
This manual page describes the format of the /etc/hosts file. This
file is a simple text file that associates IP addresses with hostnames,
one line per IP address. For each host a single line should be present
with the following information:
IP_address canonical_hostname [aliases...] |
so you could add a Two-Spear alias to the localhost entry.
