Hello again,
As I suspected, the gateway was running OK today. I telneted to it and tried
the following:
- Try pinging to a real IP address instead to eliminate any DNS problems.
I tried ping 64.233.167.99 (google.com) and it works fine now.
- In case ICMP is somehow blocked along the lines, try telneting to port 80 of
a web server on the Internet.
I really don't know how, but I tried telnet www.yahoo.com and it didn't
give any response, I appreciate it if you know any valid example.
- Further try pinging to an IP of the "company's network"
I tried to ping a printer in the company network and it works fine too.
I know Its good to be working now but I'm sure the problem will happen again.
Regarding my 2nd question, Why it is not good to reboot the machine to fix
problems (just like we often do on windows)?
and another question, How can I see Logs or information about the system and
network usage since the last boot? I know most of the system logs live in the
/var/log/ directory but most of them are not readable. and in my case
system.log is not available!
Thanks again for the help.
Mohammad.

I will try what you told me tomorrow as I left the office right now. But I
think by that time the problem will be gone (but surely not solved).This
happend before and it will happen again I guess.
I'll tell you the results tomorrow inshalla.

I'm not sure I get the whole picture but I thought I'd send you a tip for
testing.
You mentioned 'pinging to yahoo.com'
As an alternative:
- Try pinging to a real IP address instead to eliminate any DNS problems.
- In case ICMP is somehow blocked along the lines, try telneting to port 80 of
a web server on the Internet.
- Further try pinging to an IP of the "company's network"
The composite result of those three tests can better help you corner the
problem.
Keep us posted!

hello, this is a BSD Problem but I hope that someone can help.
At the office we have 2 LANs, the company LAN and our own
internal LAN for development purposes. We have a BSD machine with 2 LAN
interfaces that acts as a gateway between the 2. We use is it to access
the internet. Now everything is up and running until recently, the
gateway blocks sometimes and it stops forwarding packets. after a while
it starts to work again. Forgive me but my knowledge in this stuff is
limited so please bare with me.
When it happens, I try to ping the gateway from my machine and
it works fine. when I telnet to the gateway, and try to ping yahoo.com
from it, it doesn't!. So that means that the connection between the
gateway and the company network is not working.
My question(s):
Q1: what could be the possible reason for this. is it the gateway
itself, does is get stuffed with requests from the local machines
trying to access the internet, if yes how can I check for this
information? Or is it the Company server that blocks the gateway for a
while and then works regularly? during this time if I plug my machine
to the company network it works fine, so the problem is from the
gateway for sure.
Q2: I would like to understand the possible cause for such a problem to
solve it before the rest of the team restart the machine by force (we
are all Windows users by the way :)) so why is it not good to restart
Unix machines when such problems occur in general? is it OK to at least
deactivate the network interface instead?
Thanks in advance. Mohammad Khashashneh.
