get host name

[jlynch1]

is there any function in tcl to get the hostname of a machine given an ip address , like the c function gethostbyaddr.

Do not know about the remote hostname but you can get the local host name using:

[info hostname]

The tnm extension gives you the standard name resolution
facilities. There is a dns package available that can re-
solve names by tcp queries(My dns servers don't allow tcp
queries from non-trusted hosts so the worth of this is
debatable).
If you really need the functionality of gethostbyaddr
and can't use tnm, you could look at compiling a small
extension, or a standalone to do what you want.
If you haven't been to the wiki please check out the
resources there.
