 Posted: Mon Oct 11, 2004 12:37 am Post subject: Network unreachable |
 |
|
I try to ping my gateway and get the network unreachable error. This is a fresh install and I am in the OS through grub for the first time. (before I could only chroot in) I am intersted in learning as much about Gentoo as possible. I have gone back to the network part of the install guide and done what I can and checked to make sure most of it was still in tact.
Any and all help will be greatly apreciated.

| Did you run /sbin/ifconfig and /sbin/route with their respective commands? |

I dont know if this helps but it is asking me if I have $ifconfig_eth1 set in /etc/conf.d/net?
It is also telling me that "netmount" was not started. |

Wow long time since i have posted on this forum... But lets see what we can find out on this.
First off does your network connection work at all?
Post the results of:
Also when you did the install did you use genkernel or did you build it by hand? If you did it by hand did you include the drivers for the nic in the kernel and if so was it a module or directly in?
If you compiled it as a module then you will need to make sure that you load it on boot if you are going to be using it the whole time the PC is up.
Also make sure that you have setup the connection in the /etc/conf/net file. In there you will need to make sure that you either have it setup as a DHCP connection or Staticly assigned.

ifconfig: | Code: | lo Link encap:Local Loopback
inet addr: 127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txquenelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) |
I installed the kernel by hand and am not sure about the modules. If it is possible to check I will do so if someone can tell me how.  
I do not have an /etc/conf/net file. I tried to cat it and it did nothing then went to /etc and could not find a /conf file or directory there.
Deathwing: what are the respective commands to /sbin/ifconfig and /sbin/route? If this is even relevent any more.
Again thanx to everyone for their patience and help. I enjoy learning as much as possible about linux and Gentoo. It has been a long install but I am looking forward to having it all up and running.

Its not a config issue at this point IMO. This is what I would do: boot using the livecd, (no need to chroot in), verify that your network is up and running, run lsmod to see what module is in use for your nic. (if youre not sure write down all of em, there should only be a handful; post it here and well help) then reboot. Run lsmod again and compare the lists to determine what module is missing. Also lspic | grep -i ethernet would be helpful. Do you get any errors during boot? dmesg will allow you to sift through..
Even if you didnt compile the correct modules when you built your kernel it wont be hard to get them in there, once we know what is missing

|
|
I ran lsmod with the livecd after verifying that it does have network access by pinging something when I could not ping anything in the system its-self. Here are the results:
| Code: | module size used by Not installed
3c59x 23152 1
serial 48676 0 (autoclean)
sbp2 15284 0 (unused)
usb-storage 60800 0 (unused)
hid 19652 0 (unused)
uhci 21916 0 (unused)
usbcore 53676 1 [usb-storage hid uhci] |
here are the errors I get during boot. | Code: | eth0: unknown interface : No such device
Modprobe: modprobe: Cant't open dependencies file /lib/modules/2.4.26-gentoo-r6/modules.dep (no such file or directory)
* Please make sure that /etc/conf.d/net has $ifconfig_eht1 set
* (or $iface_ethi1 for old-style configuration)
* ERROR: Problem starting needed services.
* "netmount" was not started. |

do this and post it
dmesg|grep eth
lsmod
lspci
cat /etc/conf.d/net
ifconfig
route
also you want to post what your ip settings should be
and post you kernel's .config |

cat /etc/conf.d/net:
| Code: | iface_eth0="192.168.1.6 broadcast 192.168.1.6 netmask 255.255.255.0"
gateway="192.168.1.1"
iface_eth0="up" |
There are other notes in this file but these were the only lines that were not noted (start with #)
lsmod gave me nothing but the headers of Module Size Used by and Not tainted.
lspci told me command not found
ifconfig gave me: | Code: | lo Link encap:Local Loopback
inet addr: 127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txquenelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) |
route: | Code: | Destination Gateway Genmask Flags Metric Ref Use Iface
loopback 127.0.0.1 255.0.0.0 UG 0 0 0 lo |
My IP setting should be that I am 192.168.1.6 and my default gateway should be 192.168.1.1 and my netmask should be 255.255.255.0.
Excuse my ignorance but where is my kernel's .config file.
Again thx for all the help and patience.

lspic is usally /sbin/lspci. It may not be in your default users path, its in roots though. One problem that I see initially is that in confd.net you have your IP address and your broadcast address listed as the same. Change this. Your broadcast should be 192.168.1.255. On every network REGARDLESS of the range (wether its a full class C, B, a /29, whatever) you have a network and a broadcast address. Network address = the first address in the network, not useable. The last address in the network is also not useable, last address = Broadcast; in case you didn't know. The other obvious issue is that you dont have a gateway. You can resolve this by editing the gateway directive in /etc/conf.d/net. It'll probably be commented out at present, just un comment it and add your gateway, the .1 address. Heres what mine looks like: | Code: | root@MindW@rp grady # grep -i gateway /etc/conf.d/net
# For setting the default gateway
gateway="eth0/192.168.25.1"
root@MindW@rp grady #
|
Please post the output of lspci, and the output of lsmod. (even if they show not in use) as it will be extremely helpful here. Also can you post what happens if you:
| Code: | | /etc/init.d/net.eth0 start |
If its already started ^start^restart.
Your kernel config is found in /usr/src/linux/kernel-config.

Ok this seems to be a straight forward issue, you simply do not have the correct module/driver installed into the kernel or you are not loading it.
if the lsmod that you have listed above was when you were using the boot cd and your network was working then you will need to load/install the module that goes with "3c59x". If you are loading this as a module and not right into the kernel then make sure that you are having the module loaded on boot or before you try to connect to the network.
Load at boot entries go into:
| Code: | | /etc/modules.autoload.d/kernel-2.x |
if you want to load it manualy look into modprobe.
As far as the lspci not working, did you emerge that package?
| Code: | | emerge -va pciutils |

I just started following this forum 5 minutes ago as I had the same problem. All I had to do was put the name of the module in the /etc/modules.autoload.d/kernel-2.4 like you said, and it worked great.
Thanks for the help everyone, and hope you got yours working damon. |
