Why my network not work under my slackware?
 

This is not my first chance of using linux, but this is the most difficult problem I encountered.
I installed a clear slackware linux on my working pc(im a new employee here). But it can't access any online PCs, including the gateway. The strange story is, the network is OK for my Windows system( my working computer has a pre-installed windows xp OS) with the same network configuration.

Any idea?

You need to know a few things -- first, is the network you're trying to connect to DHCP or fixed-IP? In a Windows-based network it's most likely DHCP, but it could be fixed-IP (not usually, just maybe).

Slackware does network configuration with a utility, netconfig, which you execute (once) logged in as root (or with su - or with sudo). If your network is DHCP, choose that and you're done (reboot the system after any of these changes).

If it's fixed-IP then you need to answer a few questions when running netconfig:

• The address of the gateway,
• The address of your computer,
• The netmask.

1. The address of the gateway is numeric of the form xxx.xxx.x.x; e.g., 192.168.1.1.
2. The address of your computer is numeric of the form xxx.xxx.x.x; e.g., 192.168.1.10.
3. The netmaks is numeric of the form xxx.xxx.xxx.x; e.g., 255.255.255.0 would be typical.

You'll need to check with the network administrator to find out what those are for fixed-IP.

Go take a look at http://www.slackbook.org/html/networ...iguration.html in the Slackware Essentials book (which is on your distribution media as well).

Hope this helps some.

Oh, yes. I use netconfig as root to config my network as fixed-IP. I config it as under windows XP:
IP,netmask,gateway, etc.
Im in a office network. I want to know if the network administrator can deny any none-windows client to use the office network?
If so, how should I can by-pass that role?

Why don't you ask the network administrator?

When you write "it can't access any online PCs, including the gateway", how are you trying to access them and what are the results? ping? HTTP/S browsing? CIFS browsing? By IP address or by name?

Does the output from ifconfig and netstat -n confirm that netconfig has had the intended effect?

He is so busy that such issues will be ignore( In fact, he want all employees use windows OS).

1. ping: If ping is failed, any access would be succeeded?

A successful pring is informative. An unsuccessful ping doesn't tell you much unless pings to the same address work from the same hardware running Windows. Do they?

Sorry -- when I asked for netstat -n output I meant route -n but that's anyway irrelevant if you are having problems connecting to devices on the same LAN.

Have you tried wicd (in /extras), NetworkManager or just manually setting up /etc/rc.d/rc.inet1.conf and /etc/wpa_supplicant.conf?

1) is this a wired or wireless network?
2) Can you ping machines in the same network segment?
3) Can you ping the gateway?


BTW - You need a new network admin as these sorts of issues are what they're (supposedly) paid to help resolve.

here are a list and details of some networking tools which may be helpful to u

http://linuxhelp-rbdharnia.rhcloud.c...?namex=network

Given that that website currently gives only "Sorry! something went wrong on server" it probably doesn't help the OP much (and could even deceive the OP into thinking that there is another problem).

Thanks all.
And am so so sorry that, it's not the problem about my system, but myself.
I found there are two network adapters on my pc, and my slackware set the extra adapter as eth0 but not the one built in the mother board! Im so sorry.
Thanks all.

No worries. Thanks for the update and glad you solved it :)
