[Bug 1465220] Re: Only first six DNS search domains are used
I've also tried this on an older 12.04.4 LTS release and can reproduce the same behavior. No LSB modules are available. Distributor ID: Ubuntu Description:Ubuntu 12.04.4 LTS Release:12.04 Codename: precise Out of interest I found an old CentOS 5.3 install and I can again reproduce the same behavior there. So this doesn't appear to be a Ubuntu specific issue. However I've not found any documentation that states that the search domain will only use the first six entries. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1465220 Title: Only first six DNS search domains are used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1465220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1465220] Re: Only first six DNS search domains are used
OK, so typically after filing this and then reproducing on an old CentOS install I did some more digging. Issue appears to be that MAXDNSRCH is hard coded to 6 in resolv.h. Not a bug as such but annoying. Also tricky for those of us who have a lot of search domains, quite probably in an enterprise environment where companies have been acquired. For now the only feasible workaround may be to install a local proxy DNS server to workaround this limitation although I've not tried this. Perhaps the init scripts for networking/resolvconf could print a warning if more than six search domains are defined? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1465220 Title: Only first six DNS search domains are used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1465220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
