Changi NNTP Server 1.0

General TCP/IP Problems

It's a bad idea to try to get Changi running on a machine with an untested TCP/IP configuration or to use Chanx to test a connection to a remote host.

It's a good idea to try PING.EXE or TRACERTE.EXE first. Then, if successful, use NR/2 (or any other newsreader) and, last of all, try to get CHANGI.EXE and CHANX.EXE running.

Host Not Found, Unknown Host

Probably a host name resolution problem. Try PING.EXE to ping the wanted machine. As long as you can't get a ping response from the host, it makes no sense to continue with any of the Changi programs.

Check etc\resolv or etc\resolv2. Are they pointing to a valid nameserver? It may also be possible that you don't have a route to your nameserver. Note that even nameservers are sometimes down. If you can't get a connection to your nameserver, you may create a local etc\hosts file and add

SET USE_HOSTS_FIRST=1
to your config.sys.

Sample etc\hosts:

127.0.0.1        localhost
192.168.222.1    os2point os2point.ping.de
193.100.14.2     news.ping.de

Interface Not Configured

You need to issue an ifconfig command for the interface in trouble. To set up a local interface, enter
ifconfig lo 127.0.0.1
on the command line. Also check the TCP/IP configuration notebook. For connections to remote hosts via modem, try
ifconfig sl0
to check if the serial line interface is up.

No Route to Host

Enter
netstat -r
on the command line to see all entries of your current routing table. Use ROUTE.EXE to add or remove routing entries. TRACERTE.EXE could be helpful too.
