How can I see my servers ip address. (it is handed out dhcp). Windows is
ipconfig /all. Linux is.......

Why is the system name localhost.localhost. Why the dot abbreviated
name. Can I change this? How can I reference it. For instance from a M$
workstation if I wanted to ping it how could I ping without having to
enter the IP.

Samba lets me set a server name up but is this just for samba or can I
then reference this same name for telnet, ftp, mail settings????

When asking even basic questions like these, it is helpful to mention which 
Linux distro you are using. Since you didn't, I will try to give you 
generic Linux responses. But the major distros have their own config 
sustems, and their own peculiar kinks, so you might find some of this 
either slightly off the mark or less helpful than it might be if we knew more.

"ifconfig" is the usual command for this.

Without arguments, it reports on all configured interfaces. With the -a 
argument, it reports on all interfaces. For more, try "man ifconfig".

Some distros use the command "ip" instead. I believe "ip link" is the way 
to get interface info.

>Why is the system name localhost.localhost.

During installation, distros assign a default hostname and a default domain 
name. Some ask you if you want to change it; ithers don't.

>Why the dot abbreviated
>name.

Not sure what you mean by "dot abbreviated". I don't see any abbreviations 
in "localhost.localhost".

Actually, I would have expected it to read "localhost.localdomain", with 
the first part the hostname, the second part the domain (network) name.

>Can I change this?

Depends on what exactly you want to change. On the system itself, this name 
is in the file /etc/hostname. Possibly you can just edit this, but that 
might not survive a reboot, since on some distros, this file gets 
overrwritten by one of the boot/init scripts.

In this context, "reference" is a meaningless word. So I'm only replying to 
your "for instance".

It depends on how the "M$" workstation resolves names. Either put it in the 
Windows workstations hosts file (which translates between hostnames and IP 
addresses locally) or add it to the appropriate file on your DNS server. 
Without knowing more about your LAN (or your Internet conenction, if you 
are talking about pinging from teh Internet), I can't be more specific.

I'm not a big Samba user, but I believe this name entry is just for Samba. 
For standard Internet services, like the list you gave, you need to provide 
a namaddress pairing that the resolver on any host you want to "reference" 
the name from can access. This means either that system's equivalent of the 
/etc/hosts file ("man hosts" will explain this file on Linux systems) or an 
entry on whatever DNS server the system uses to resolve FQNs 
[Fully-Qualified Names, like the parts of normal e-mail addresses after the 
@ sign).

It Does. So the names on an internal network are meaningless. For
instance it could be set to myserver.mynetwork. 
Does the windows workgroup mean anything to Linux?

I do not see how reference is meaningless in this context. I wish to
"reference" the server by name rather then by ipaddress.

This server resides on a peep-to-peer network. In the windows
environment there is a master-browser that maintains a list of all the
computers so they can be "referenced" by name rather the IP. This
browser can change by standard M$ election rules. I do not want to add
this server to every workstations hosts file especially because the ip
is handed out from a router using dhcp. Which is also why I don't want
to have to always do it by ip address. This is all for an internal
network not the internet.

I'm not going to get in an argument with you. Let's just leave it that I 
don't know what you mean, to the extent that you meant anything more than 
the "for instance" you gave. Perhaps someone else will be able to help here.

This is really a Windows networking question now, not a Linux question as 
such ... and I'm not expert on Windows-based networks. How does this 
Windows "master-browser" handle resolving the names of *any* device other 
than a Windows workstation or server (e.g., a Macintosh or a router)? 
Handle this Linux host the same way. (Doing this might involve getting more 
help with Samba than I can give you.)

In a Linux framework, BTW, the usual solution would be for the DHCP server 
to handle it. It would include a hostname assignment in the lease info (or 
it would use a MAC-address tie-in to associate a static address with the 
host - usually, you want *servers* to stay put with respect to their IP 
addresses anyway). And it would run a DNS resolver that provided the 
name-address translation on-LAN.

Ray, i dont want to conradict you but, "ip" is a linux command so i cant see 
how it could be a distro spesific command, mind you i am not saying that it 
is not either.

ip which used to be a seperate linux routing command it was first implimented 
in an archive called iproute2 it is now included in slackware and AFAIK some 
other distro's.

One uses 'ip' mainly for routing via tunnels. 

ip -V returns;
ip utility, iproute2-ss990824

We are not really disagreeing, Richard, just saying the same thing a bit 
differently.

As far as I know, the iproute package is available for all the major 
distros, and some of the minor ones. But Debian, to choose the example I 
know best, does not include it as part of a default install. You need to 
install it separately. The "ip" command also requires that the kernel have 
some options enabled, options that not all stock kernels use (I forget the 
exact ones right now or I'd be more precise here).

At least one specialized distribution, LEAF, uses ip *instead* of ifconfig 
(and route); those two commands are not part of a default LEAF install. 
Since I don't know what ALL the major distros are up to these days, I 
didn't want to leave the original poster high and dry if he happened to be 
using a distro that did not include ifconfig (it wasn't until a later 
posting that he mentioned using Red Hat, so I didn't know at the time what 
he had installed). So I mentioned ip just in case.

The "ip" command can almost completely replace ifconfig and route. (I say 
"almost" because I haven't found an equivalent for "ifconfig -a".) In at 
least one specialized distro I am familiar with, it does replace them. In 
environments where both choices are available, I expect you are right about 
the usual use of "ip".

You wont find it on slackware-8.0 if i remember correctly, it was first 
included in the most recent release, 8.1.

Cheers.

It may be there but not in your path:

[jdr@pyro2 jdr]$ /sbin/ip -V
ip utility, iproute2-ss001007
