Perhaps this is an issue in iputils/ping if the response is to big. You can try this with normal ping command too.
ping c1 chat.freeenode.net results in a "ping: chat.freenode.net: Temporary failure in name resolution" Using expicit -4 or -6 does work instead. Workaround as mentioned above: switch "resolve [!UNAVAIL=return]" to "resolve [UNAVAIL=return]" or place "resolve [!UNAVAIL=return]" after "dns". ** Also affects: iputils (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1665394 Title: DNS resolution of irc.freenode.net or chat.freenode.net fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iputils/+bug/1665394/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
