Jeez, what a day. I've had my first taste of Linux network troubles but have no idea what to do.
I have a LAN with all W2K machine but our development box is Linux Mandrake. The Linux box has 2 ethernet cards - one for the network hub and the other for a router to the net.
Now, this morning it was all happy until our W2K Server needed DHCP and DNS reconfigured. Nightmare.
Before, I would access the Linux box externally on the net via an IP address, like 220.127.116.11. This was available publicly on the internet and was configured with Apache 1.3 and Tomcat 3.2.1.
Last night I installed Tomcat 4 and got this working and it was ok this morning too so it is not that.
Now when I access the IP I get Server Error 500. I tried accessing the Linux box over it's local IP address instead and this failed also. Therefore I thought it was an Apache problem.
So I installed Apache 2 and accessed this OK over the LOCAL intranet. HOWEVER, still not luck with this over the EXTERNAL IP. So not Apache....must be a networking issue here I think.
Other information ... I can ping the external IP from a computer NOT on the intranet. I can also PING the IP from the Linux box itself.
I am just totally lost. At the moment I have a workaround by going over the LOCAL intranet IP to Apache 2 and Tomcat 4 but I need the external IP up so I can work at home!!!
Any ideas? I need 'em! Thanks
