/etc/hosts Not Resolving Hostnames
into an interesting problem executing GAMESS jobs on my older G4 (see error below). I am sure that the problem is operating system related, but I'm a bit puzzled as to its resolution. It host not found 3(nxdomain) ubuntu appears that something is missing (specifically the computer's local alias) but after editing /etc/hosts, /etc/hosts.allow, /etc/hosts.conf and using the Apple Utility (there's an oxymoron) 'Netinfo' to copy the assign the macintosh.local alias to the IP address assigned to the G4, the problem is still not resolved. I've gotten WebMo and GAMESS running on several Linux boxes, but am stumped by this one. Command line jobs using the gms gethostbyname returns null and rungms scripts supplied with GAMESS work without a hitch. I've attached the error message from the WebMO job manager below. Any help would be greatly appreciated, Jason Hurlbert Distributed Data Interface kickoff program.

WebMO tries to pass it this hostname when it starts a calculation. In this case, it looks as if the hostname is being passed as null. The hostname is stored in the WebMO configuration file, and is normally set during WebMO installation; however, it currently seems to be set incorrectly. Try the following. Open up the WebMO configuration file, globals.int, located in the 'interfaces' subdi

Why does the host command not resolve entries in /etc/hosts? linux ubuntu domain-name-system share|improve this question asked Apr 11 '13 at 18:13 user784637 73252040 add a comment| 4 Answers 4 active oldest votes up vote 29 down vote accepted The host program uses libresolv to perform a DNS query directly, i.e., does not use gethostbyname. Most programs, when attempting to connect to another host, invoke the gethostbyname system call or a similar function. This function obeys the configuration of /etc/nsswitch.conf. This file has a line which in Ubuntu 12.04 defaults to the following: hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 which means that it will first use /etc/hosts, then fall back to DNS queries. If you want to perform a host lookup this way, you can do this with getent hosts. For example: $ getent hosts serverfault.com 198.252.206.16 serverfault.com I hope this helps. share|improve this answer edited Jun 14
