[gentoo-user] Name Resolution Problem
I am relatively new to Gentoo and I am having a problem resolving localhost. I always get "unknown host localhost" I can connect to any other site such as www.yahoo.com but nothing else works. I have gone through the Gentoo Handbook several times and googled the issue but could not find a resolution. Please let me know what you files you might need to look at to troubleshoot the issue. Thanks, Russ -- gentoo-user@gentoo.org mailing list

Thanks, Russ Normally localhost maps to 127.0.0.1 inside /etc/hosts (see the hosts(5) manpage). This file basically allows you to override the normal DNS resolution process for specific host names.

Re: [gentoo-user] Name Resolution Problem
The /etc/hosts file has the only the following entry in it: 127.0.0.1 localhost I cannot get the system to reconize anything that I place in /etc/hosts. For some reason it does not appear that the /etc/hosts file is being processed. Is there a config file somewhere that specifies whether or not the hosts file gets processed? My system is setup for DHCP and resolv.conf gets overwritten every time the system is booted. Any ideas?

Re: [gentoo-user] Name Resolution Problem
lo is up, verified with ifconfig. I can ping 127.0.0.1, however pinging localhost results in "ping: unknown host localhost". I get the same result with anything else that I add to the hosts file.

Re: [gentoo-user] Name Resolution Problem
check 'man dhcpcd' to check the arguments to pass to it (via /etc/conf.d/net) to prevent it overwriting local config files like /etc/resolv.conf. Are you using a local bind server? recent updates to localhost processing in a recent gentoo update did the same for me with clients on other machines (principly firefox, but sometimes other apps). eventually I overwrote the gentoo supplied localhost and 127.zone config files with my own and now its all sweet. I dont know why browsers seem to ignore /etc/hosts, but firefox, mozilla and I think IE all do. My /etc/nsswitch setting is files DNS which should make apps check /etc/hosts first.

Thanks, Russ I would try strace now to see if /etc/hosts is being opened: strace -e open ping localhost (if that generates too much lok at man strace, there is an option to save to a file - redirection does not work IIRC.) -- Nick Rout -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] Name Resolution Problem
Thanks Nick! strace showed that /etc/hosts was not being opened, but it showed that nsswitch.conf was being opened but did not exist, so I created a nsswitch.conf file with the following line: hosts: files dns Now everything works.

Re: [gentoo-user] Name Resolution Problem
nsswitch.conf has a number of other entries in it which if missing may give rise to similar weird problems like this. You might like to extract it from sys-libs/glibc (the owner on my system) and replace it with the full file.

Re: [gentoo-user] Name Resolution Problem
No idea why the file wasn't there. I certainly didn't delete it becauseI never even knew it was there.
