Irssi IP/Hostname question

Hi there

I'm using Irssi since a few days and I feel lucky with it. I
run it on
my dedicated SuSE server in conjunction with the great
GNU/screen. So
when I'm connected to a IRC server, the /whois command gives
me back
something like that:

21:39 -!- herr_schnegg [herr_schneggxxx.xxx.xxx.xxx]
(cut)

Is it possible to show just the hostname of my dedicated
server? When
I'm connected using my desktop pc, /whois gives me back the
hostname,
such as, herr_schneggblabla.provider.tdl

Thank you for your comments!

Daniel

irssi can use any non-rfc1918 (that is 192.168.x.x,
172.16.x.x,
10.x.x.x, etc) ip that is configured on your machine, and it
will use
the reverse configured for that ip address.

see the -h parameter to irssi, and/or see the /help for
/connect,
/server and /network.

if the ip address you'd like to use is not configured on the
machine you
are running irssi on, you can't make irssi use that
hostname, as this is
not controlled by irssi, but by the irc servers, which
reverse the IP
address the connection is comming from.

That would be because your dedicated server has another IP
address and
another reverse than your desktop pc at home.

Yes it is, but for that you need to have a PTR in a DNS that
points that
ip to a hostname. Generally, this is done by your ISP.

I used yast to configure the hostname for my public ip
address. one of
the entries is:

127.0.0.1 localhost

now I created another with my public ip address (the same as
/whois
gives back), mydomain.tdl as Host Name and also mydomain.tdl
as host
alias.

Is that correct?

Now I started irssi by using the following command:

irssi --hostname=mydomain.tdl --nick=herr_schnegg
--connect=myircserver

but /whois nevertheless gives back my public ip.

That is correct, but this only sets the name for your local
system when
it does lookups. This setting does *NOT* affect how the
other hosts on
the internet see your 'hostname'. Read below.

Ok. Your internet connection as a public IP address, say
111.112.113.114.  This IP address is provided by your ISP. 
The IP
address has a reverse (that is, a hostname, say
111-112-113-114.dsl.isp.net). This 'reverse' is configured
by your ISP.

When you connect to an IRC server (like IRCnet, Undernet,
Efnet, etc),
the IRC server only sees a connection comin from
'111.112.113.114'.
Internet works with IP addresses, hostnames are invented
because people
were too dumb to remember all those ip-addresses.

So when you connect to a server, it sees your IP address and
looks up
what name belongs to that IP address. This name is the
reverse
(hostname) your ISP has configured for that IP.

There is *no* way you can change this reverse name
*yourself* if the
IP-space is not maintained / configured by you. You might
try asking
your ISP, but the chances they'll change the name are slim.

I hope my story is clear ;)
