This specific issue (the FATAL error) is fixed on >= Bionic and therefore I'm marking the Bionic task as Fix Released.
However the script "</dev/tcp/127.0.0.1/53" syntax doesn't currently work on any supported version of Ubuntu, but for a different reason: it relies on /bin/sh being Bash. I filed a separate LP bug for this problem with more details: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/1934300 however for the moment my suggestion is to use alternative ways to check if a TCP port is open, e.g. something like: script "bash -c '</dev/tcp/127.0.0.1/80'" script "nc -z 127.0.0.1 80" ** Changed in: keepalived (Ubuntu Bionic) Status: Incomplete => Fix Released ** Changed in: keepalived (Ubuntu Bionic) Assignee: Paride Legovini (paride) => (unassigned) ** Tags removed: server-next -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795420 Title: Keepalived update from 1.2.19 to 1.2.24 breaks support for /dev/tcp health check To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/1795420/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
