lan connections troubleshooting
Hello everyone
I've installed fedora 12 at work on a lan aside with windoze xp, ( where only windozes are connected ) but the I can't surf the net (or yum update ) as I do on windoze xp, I 'm given a static ip to assign to my eth0 card of the kind 172.16.15.50 + gateway 172.16.15.1 + a dns ip of the same kind , using a default config fedora 12 install
the network manager service is down.
please help me troubleshoot this, as I don't know if the sys and network admin will be very "cooperative"
thanks

Re: lan connections troubleshooting
Hi
Open a terminal and run
Quote:
[robert@sun ~]$ ifconfig -a
eth1 Link encap:Ethernet HWaddr 00:1E:8C:9B:B9:7C
inet addr:192.168.220.9 Bcast:192.168.220.255 Mask:255.255.255.0

This should show your address (172.16.15.50), and UP
If you have an address, can you ping the gateway ( My gateway is 192.168.220.254 )
Quote:
[robert@sun ~]$ ping 192.168.220.254

If you can ping the gateway, check the DNS is working with
Quote:
[robert@sun ~]$ host forums.fedoraforum.org
forums.fedoraforum.org has address 208.43.111.170
|
If all of the above are working, does the webbrowser require a proxy setting ?

Re: lan connections troubleshooting
Thanks replying
I'm not now at work but I've tried ifconfig and it shows the eth0 card is up, i 'll try "ifconfig -a" once I get there, and yes I can ping the gateway.
I haven't checked DNS yet
there is no proxy settings to do,
I'll keep you informed

Re: lan connections troubleshooting
Assuming you can ping the gateway, I also like to check that it can get beyond the gateway.
ping 4.2.2.2
is the address I find easiest to remember, a publicly accessible DNS server--Verizon's, I think.
If you can ping that, but can't ping something by name, e.g., google.com or yahoo.com, then you know the issue is a DNS issue. If you can't reach 4.2.2.2 by number, then it's a routing issue.

Re: lan connections troubleshooting
smr54 -
It's not related to the OP but 4.2.2.2 is a backbone dns (backup) service operated by Level3/GTE (is that Verizon?) and not "public" in the sense of free for all to abuse.
It's downright rude to us it for testing.
Please use 8.8.8.8 (even easier to remember) or 8.8.4.4 which are freely accessible public google dns servers.

Re: lan connections troubleshooting
Thank you. I'll keep that in mind.
And, you're quite right--it's easier to remember 8.8.8.8

Re: lan connections troubleshooting
This is something that might cost you your job if you are not authorized to use the network. I wouldn't underestimate the admins. It's not difficult to watch for new hardware.
Maybe you can persuade management to let you use your OS?
