Need identd for port 113 ? Install authd

yum install authd

Happy identing :)

Actually it's not that simple.
It installs as an "xinetd" service and is disabled and turned off by deafult.

To enable it run:

[code:1:8c94df8319]
chkconfig --level 3 auth on
service xinetd restart
[/code:1:8c94df8319]

This will set identd aka authd to start by default.
service xinetd restart will turn it on immediately so you don't have to restart

Now you should be able to telnet to port 113 and get a response.

At this point in my case it doesn't work and is not configured so I'll let you know when I've figured that out :)

I've tried all kinds of things but I just can't get the identd to reply with the actual username.

I've actually manually compiled oidentd and ran it in the foreground with

[code:1:f2e2b93fe1]oidentd -di[/code:1:f2e2b93fe1]

and it works just fine.

I even added the same thing to /etc/xinetd.d/auth

and it won't work still just like the authd rpm.

And let me tell you there's almost no tutorials or documentation on this!

In Centos you'll need to download oidentd from sourceforge and manually compile it first.

[code:1:e2afc4d2ee]./configure
make
make install[/code:1:e2afc4d2ee]

I edited the entry in /etc/xinetd.d/auth
like so.

I changed the "server" path to oidentd

I read that oidentd 2.0.7 won't work with xinetd.d especially newer versions but that is not true!

If you use "-d -i -I" as the server_args it works just fine.

Just use the example below.

[code:1:e2afc4d2ee]service auth
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = ident
server = /usr/local/sbin/oidentd
server_args = -d -i -I
}[/code:1:e2afc4d2ee]
