nic working but not accepting incomming requests

digitalgravy · 01-23-2004, 03:19 PM

I just moved from Redhat 9.0 to Mandrake 9.2.

I am having trouble with my network.

I have manually specified my ip address and all relevant info.

I can get on the net and I can ping my windows box from my linux box.

I cant telnet, ssh or ping my linux box from my windows box though.

When I ping my linux box from windows it says "Request timed out:
When I telnet my linux box it says "Connection to host lost"
When I log in to my web hosting companies box and telnet my linux box it says "Connection closed by foreign host"

I have set the firewall to accept all incoming requests.

I don't know what to do.

Thanks for any help in advance.

First, check out your firewall by turning it off and see if you can ping/telnet/etc.
Then see if xinetd has been set up to accept ping and telnet.

I already had the firewall turned off, that was the first thing I tried.

As for the setup of xinetd, I do not know how to do that.

But basically, When I am on my windows box and I open the Command Prompt and issue a ping command the the ip address of the linux bow it says Request timed out, I can't even ping the box al all.

Thanks

I looked somewhere else and it said to see what the routing tables are:

Here is the output from /sbin/route

Code:

Kernel IP routing table
Destination        Gateway          Genmask          Flags Metric Ref     Use Iface

Nevermind.

I tried a few things, and I looked into the system security level section of the control center. I had it set on the "Higher setting." According to the documentation it says that this setting should be used for a server accepting connections from many clients. Well it blocked everything.

I set it to High, one setting below. Now I can telnet and ssh to my linux box.

But I still cannot ping the box. Everytime I try it still says request timed out.

If anyone knows why, I would like to know.

Thanks
