I can telnet to the port just fine, though. 1353246414 Q * shaggy64 1353246427 Q * shaggy65 1353246671 M * aurel42 I find it especially confusing that setting the prefix != 32 does not actually change the interface configuration in the guest, it's still "Mask:255.255.255.255". 1353246704 M * daniel_hozac did you turn the guest off before changing the prefix? 1353246738 M * aurel42 No, but I restarted it after I changed the prefix, of course. And ejabberd is working now. 1353246766 M * daniel_hozac then it would have failed to remove the old IP and to add the new one 1353246789 N * Bertl_zZ Bertl 1353246794 M * Bertl morning folks! 1353246820 M * Bertl aurel42: which means, you are still using /32 for the guest :) 1353246838 M * aurel42 daniel_hozac: so, since ejabberd is working now, and the prefix change didn't actually become effective, the nflag ~single_ip is all I need? 1353246848 M * Bertl correct 1353246849 M * aurel42 Which makes it even more confusing for me. 1353246855 M * Bertl how so? 1353246941 M * aurel42 The docs are a little thin on what single_ip actually does. "Enable special handling of network contexts with a single IP only" 1353246984 M * Bertl obviously, your kernel has AUTO_SINGLE_IP enabled, so without ~single_ip (the negation of single_ip), a guest with a single IP will use that special casing 1353246988 M * aurel42 This network context only has a single IP, yet Erlang barfs unless I turn this feature off. 1353247014 M * Bertl as result, all traffic (e.g. to 127.0.0.1) will be remapped to that single IP 1353247026 M * aurel42 Yes, all my guests use single_ip and seem to be happy with it, at least I'm not aware of other problems, except with erlang/ejabberd. 1353247047 M * Bertl now if a process checks for connections coming from 127.0.0.1, it will fail for single_ip, but succeed with ~single_ip 1353247078 M * aurel42 Bertl: hmmm, erlang/ejabberdctl/ejabberd are all configured to talk to each other on 194.97.x.x. 1353247120 M * Bertl obviously there are other checks or hardcoded stuff there ... 1353247161 M * Bertl you can simply check the actual packets on the host (with tcpdump) or the connections on the process in question (via strace from inside the guest) 1353247165 M * aurel42 Oh, there's one visible change with ~single_ip. epmd was listening on 194.97.x.x before, now it decided to listen on 0.0.0.0. 1353247223 M * Bertl I presume your epmd checks for 127.0.0.1 at some point 1353247239 M * Bertl might it be a configuration issue or a design feature 1353247315 M * Bertl and to fix the prefix, which you should set to the correct value, you simply stop the guest and remove the guest IP manually from the IP stack 1353247485 M * aurel42 I assume I should treat erlang as a special case because of that three-letter "feature", and not make ~single_ip the default for all my guests? 1353247812 M * Bertl there is a small penalty for not using single_ip (performance wise) but unless you have a really high density or huge number of connections, it will not be noticeable and ~single_ip will be more flexible 1353247992 M * aurel42 Sweet, no, the guest systems are not really that busy, they're mostly running services that have seen the best of their days already. 1353248036 M * aurel42 Thanks a lot, daniel & Bertl. brb - the guest in question unfortunately is "my" jabber/irc box. 1353248039 Q * aurel42 Quit: leaving 1353248187 J * aurel42 ~aurel@sid.a42.de 1353248250 M * aurel42 The time of confusion has cometh to an end!
