[solved] Unable to resolve any hostnames, including localhost


I've been building a custom Linux system for my old 486 laptop, based on a 2.4.31 kernel. At one point networking was working perfectly, but I changed something and now my laptop cannot resolve any hostnames to ip's, including localhost. To simply the problem, please note that this occurs without any modules loaded or pcmcia service running (so I'm not concerned with getting online right now, just being able to resolve localhost into will be enough, because I'm convinced my other networking problems will go away as a result). I've spent a few hours on #linux being helped by some very nice people, with no luck.

Linux kernel:

Homemade UMSDOS (original based on latest mulinux, but completely gutted and refitted with new kernel, libraries, and binaries (I just needed a UMSDOS filesystem to get started), with new binaries and libraries copied over from Ubuntu Breezy. My plan is to get it working enough to get online, then use apt-get / dpkg to set up the system properly.

Code:          localhost         loopback
(Note: there are tabs between each, not spaces. I have also tried simply ` localhost'. I have also tried space instead of tab.)

order hosts,bind
multi on
lo        Link encap:Local Loopback  
          inet addr:  Mask:
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:1344 (1.3 KiB)  TX bytes:1344 (1.3 KiB)

Networking commands that I run during the boot process:
/bin/hostname mubuntu
/sbin/ifconfig lo
/sbin/route add -host lo

Kernel `make menuconfig' networking configuration:
General setup:
[*] Networking support
Networking options:

<*> Unix domain sockets[*] TCP/IP networking
Network device support:
[*] Network device support
<*> Dummy net driver support
Thank you very much for your ideas and suggestions on how to get localhost to resolve to

There is another file called resolv.conf you did not mention which contains the addresses of the name servers. Perhaps it does not exist or is empty. I think any IP search needs this file and its absence would cause failure.

I do have /etc/resolv.conf, but I should note that it is created automatically when I run dhcpcd (so it has nameserver entries related to my isp only). I wasn't aware that it was needed to resolve localhost. What should it contain to resolve localhost to

I have tried with and without the resolv.conf file and it doesn't seem to make a difference. I'm not trying to get online right now (so please don't worry about dhcp or dhcpcd, it's not running.. I don't even have the network card in). Just being able to `ping localhost' and have that work is enough. AFAIK, that shouldn't require dhcp or a network card, since it is the local networking system.

I don't normally build a machine without a NIC. I wonder if this would have something to do with it. The relationship between localhost and should always be there but if there is no NIC perhaps it is broken. The other necessary files to check are protocols, services, and networks all found in /etc. Perhaps the answer may be found in these? Not sure what else I can think of.

Ahh, sorry I don't want to confuse. I can plug in the NIC or not (run dhcpcd, which works, etc), it doesn't seem to make a bit of difference. In fact, with the NIC I can ping internet sites and access them by IP.. but I didn't want to get into the details of the internet configuration. I believe that my online DNS problems have a root cause that is the same that is causing localhost to fail to resolve to If my theory is wrong, that's okay, but it's a separate issue, so I didn't want to confuse the situation, but keep it simple instead.

So, to summarize that: I'd like to be able to access localhost and have it resolve to, regardless of whether I can access the rest of the internet by DNS resolution or not.

Would you be willing to share the contents of the files you mentioned? I will compare against what I have. Maybe I'm missing something basic, as I put this together myself rather than using packages.

Check you /etc/nsswitch.conf file. In the line "hosts: " make sure "files" is listed. Here is mine:

# /etc/nsswitch.conf
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd: compat
group: compat
shadow: compat

hosts: files dns
networks: files

protocols: db files
services: db files
ethers: db files
rpc: db files

netgroup: nis
PS: if you use nscd (ps xa|grep nscd) then you might have to restart it (/etc/init.d/nscd restart) after making changes to this file.

Solved it! I was missing the /lib/libnss* libraries. All works well now. Discovered this from reading the busybox Login/Password use internal functions Help option. I wouldn't have recognized it for what it was unless /etc/nsswitch.conf was mentioned.. so thanks bluej .

Thanks a lot for everyone's help,
