Network config

Hello,
I've used Salix OS which I installed on my professionnel computer for few weeks.
It works very good but the configuration of the network could be improved I think.
On login, I am connected to the entreprise netword and I can access to shared folders. But I can't go on the web, unless I do

Code: Select all

su; dhcpcd
to have an other ip. Afterwards, no problem to navigate.
:arrow: How could I config the network to have directly access?
I have so a few question about the netword in Salix OS.
:arrow: What is the file to configure the netword?
:arrow: Is there a default software to manage network (like wicd)?
:arrow: How can I know if one is already installed?
:arrow: And which of them fits the best with salix xfce?

There are so a lot of questions and I will be happy if someone have some of answers?

Thank you and thank linux, the best os.

Wicd should handle dhcpcd for you and you can use it from the shell.

The default Slackware networking script is can be configured via /etc/rc.d/rc.inet1.conf, you can also use the netconfig command for basic network configuration.

Thank you for wicd. I used it before with good result. :)

However, I don't manage to configure the network to have all access I want.
I can go through the shared folders, but not on the web or get my mails with thunderbird.
This is my ifconfig after login :

Code: Select all

eth0      Link encap:Ethernet  HWaddr 00:0c:6e:46:cc:de  
          inet addr:192.0.1.202  Bcast:192.0.1.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:6eff:fe46:ccde/64 Scope:Link

          TX packets:40 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:11285 (11.0 KiB)  TX bytes:4832 (4.7 KiB)
          Interrupt:22 Base address:0xa000 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
And now, after dhcpcd, afterwards, all is ok.

Code: Select all

          inet addr:192.0.1.202  Bcast:192.0.1.255  Mask:255.255.255.0

          Interrupt:19 Base address:0xc000

          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
Is it possible to have immediatly after login this connection, without doing a dhcpdcd each time.

Thank you.

Well, I think you should be able to just clear the Use static IPs and Use static DNS boxes in the WICD properties page.

But if that does not work, and since you know that the problem is fixed by running dhcpcd, you can just add dhcpcd to rc.local:

Code: Select all

echo "dhcpcd eth0" >> /etc/rc.d/rc.local
I suspect you already know how to do this anyway, but I am curious about why this is happening in the first place.

From my rather basic understanding of networking - which I'm sure the experts here will correct if I'm wrong - it seems that it is a routing problem, since you can see the local network. When you use DHCP, the server provides this information, but you need to provide it in the static case. You may be be able to check this by inspecting the output of :

Code: Select all

/sbin/route
in both cases.

Not sure this is the problem but first I would fix your private network addressing, 192.0 .X.X is not a legal private address. Needs to be 192.168.x.x.

I tried but no more result.

Here is the result of /sbin/route

The beginning of the ip adress in the dhcp are defined to 192.0.1.51.

I register my computer on dhcp server of the network with ip 192.0.1.202.
Do not work. I have to do dhcpcd to have this adress 192.0.1.65.

I changed in wicd config eth0 by eth1. But no more result. And besides, now, I see no interface in wicd.

Next step, I change the config in dhcp on 192.0.1.199.
I reboot on 202, and dhcpcd does not give me 192.0.1.199 but 202 :
