This sounds like an issue that we needed to solve for ORBit-1 to ORBit-1
tcp/ip connections. The question, however, remains in that case: howcome
some methods do work and some specific methods don't during the same
session?

Is ORBit-2 using different resolving-techniques for different data
structures?

However, both client and server can resolve the hostname and ip-
addresses correctly. To fix the issue above, we added this line at the
serverside:

192.168.0.23    linux-2

It makes the server resolve it's own hostname to his network ipadress in
stead of localhost.


At the server:
[pvanhoof linux-2 Linux_Srvr]$ cat /etc/hosts
192.168.0.23    linux-2
127.0.0.1       localhost.localdomain   localhost
[pvanhoof linux-2 Linux_Srvr]$


At the client
[freax lort eazyx]$ cat /etc/hosts
127.0.0.1       localhost.localdomain   lort    localhost
# Maia
192.168.0.23    linux-2
[freax lort eazyx]$

Also note that the named for this network is also configured correctly
[freax lort eazyx]$ cat /etc/resolv.conf
; generated by /sbin/dhclient-script
search maia-scientific.com
nameserver 192.168.0.2
[freax lort eazyx]$ nslookup linux-2
Server:         192.168.0.2
Address:        192.168.0.2#53
 
Name:   linux-2.maia-scientific.com
Address: 192.168.0.23
 
[freax lort eazyx]$


This is the IOR-string (I can't make much out of it myself):

IOR:010000001200000049444c3a457a78532f537276723a312e3000000002000000caaedfba54000000010100002c0000002f746d702f6f726269742d7076616e686f6f662f6f72622d32303336343438393438333433333536303037000000000018000000000000001013b87e5139df3e01000000ff2d996cf666a4340000000044000000010100001c0000006c696e75782d322e6d6169612d736369656e74696669632e636f6d000797000018000000000000001013b87e5139df3e01000000ff2d996cf666a434[
