Slackware 12.1: Fixed IP Address Not Working
I installed Slackware 12.1 on a Dell Inspiron 6000 (laptop) -- a clean install, not an upgrade -- and I cannot communicate with any internal server or the network printer; I can ping the gateway (192.168.1.1) and I can ping "myself" (192.168.1.20 or by name, "snafu") with no problems. I cannot ping another server (192.168.1.10) or printer (192.168.1.15) although I can, strangely, ping news.google.com (both with and without packet losses). I have the addresses and names of the servers and printer in /etc/hosts and I have the network configured exactly as it was with Slackware 12.0 -- I use fixed IP and have done so with this machine and this local network configuration for some years; same netmask, same gateway (a Linksys router), same everything (from, I think, Slackware 10.x through 11.x and 12.0).
The output of ifconfig -a, netstat -rn and everything else I can think of looks like I expect it to; all the pertinent stuff I can think of looks like below. Is there some funky thing about Slackware 12.1 that I've missed? I do know that the wireless stuff came up without prompting but that doesn't seem to appear here. Any help is deeply appreciated. Code:
ifconfig -a |
Hi,
How do you have your DNS setup? edit: Quote:

Uh, the "com" is the local domain name (at least that's what I've had in resolv.conf for... well, quite a while -- like years -- with no problems). If I remember right the network wizard at work (who managed about fifty Sun servers) said to stick that in the search list and the manual page seems to bear that out. Could, of course, be dead wrong about that (and the machine I'm writing this on has exactly that in resolv.conf and has since 10.x (I think).
Took that out, doesn't work for squat. Odd thing -- I can ping the system by name or address and it's fine; I can ping the gateway, it's fine; I ping either of the other services (192.168.1.10 or 192.168.1.15) and "Destination Host Unreachable." I dunno. |
Perhaps you could try blacklisting the ipv6 module. Appears to have helped some others.

OK, tried blacklisting ipv6, rebooted, no joy in Mudville (thing won't even ping the gateway).
So, I'm wondering... I installed the default kernel. This thing is a laptop (and everybody knows that laptops are weird) and I'm pretty sure it's a Pentium (bearing in mind that Slackware 12.0 worked just fine with the SMP kernel) and maybe I should have used a different kernel? Right now I'm reinstalling (yeah, using the same default kernel) just in case I did something stupid without realizing it). This one has me stumped. |
Would I be correct to assume eth1 is the wireless card (that is not configured)?
If so, I don't see why this is coming up at all in the output of ifconfig (based on the snippit of rc.inet1.conf you showed). Again, if this is true, try disabling the radio with the function keys on the laptop keyboard and restart rc.inet1 (or reboot) and see if you get an ifconfig output without eth1 listed. Then see if you can reach these other addresses. What wireless card are you (not) using? |

You can also use nmap to scan for present hosts on the network. |
I did a complete reinstall (this time the Ethernet cables was not plugged in during installation, only difference, an I can not imagine why that would have mattered).
The machine can talk to the LAN, talk to the world, what the heck talk to the animals as far as I know. Why it works now and did not work previously, I do not know, alas. Thank you to all for your time and effort (and I wrote down all those great hints for future reference, too). All is well that ends. |
