Category: Other Group: None Status: Open Resolution: None Priority: 4 Private: No Submitted By: kostos (kostos) Assigned to: wimpunk (wimpunk) Summary: Timeout option doesn't prevent hangs Initial Comment: Hi, i have Aolynk DR814 ADSL modem which is hanging from time to time and wifi-router (Dlink) connected between ADSL modem and server running ddclient. In this configiration, when ADSL modem hangs, ddclient also hanging with message like " ddclient - read from 192.168.1.1 .." and still hanged infinitely, even after modem restarted, regardless timeout option is set. As W/A i have changed the source code line below: local $SIG{'ALRM'} = sub { $timeout = 1; }; to close socket descriptor when timeout happens: local $SIG{'ALRM'} = sub { $timeout = 1; close($sd);}; Not sure is it good enough solution, but after week of testing (2 or 3 hangs happened) - it seem working, ddclient didn't hang since. Could you please check if it possible to include similar change into release? P.S. Could you also please consider small extension of functionality: in my feeling, it would be not too bad idea to log error message when timeout happens, or even better - to call external script given by option parameter to try to fix the issue. ---------------------------------------------------------------------- Comment By: Cyril VINH-TUNG (cvinh) Date: 2009-08-16 17:57 Message: Hello I have exactly the same problem with web checkip. ddclient hangs at : CONNECT: checkip.dyndns.org CONNECTED: using HTTP SENDING: GET / HTTP/1.0 SENDING: Host: checkip.dyndns.org SENDING: User-Agent: ddclient/3.7.3 SENDING: Connection: close SENDING: I tried to modify the script with local $SIG{'ALRM'} = sub { $timeout = 1; close($sd);}; but I have a segfault after timeout (20s) and ddclient daemon crashes : Aug 16 07:41:53 videosurvey ddclient[8215]: CONNECT: checkip.dyndns.org Aug 16 07:41:54 videosurvey ddclient[8215]: CONNECTED: using HTTP Aug 16 07:41:54 videosurvey ddclient[8215]: SENDING: GET / HTTP/1.0 Aug 16 07:41:54 videosurvey ddclient[8215]: SENDING: Host: checkip.dyndns.org Aug 16 07:41:54 videosurvey ddclient[8215]: SENDING: User-Agent: ddclient/3.7.3 Aug 16 07:41:54 videosurvey ddclient[8215]: SENDING: Connection: close Aug 16 07:41:54 videosurvey ddclient[8215]: SENDING: Aug 16 07:42:14 videosurvey kernel: ddclient[8215]: segfault at 8 ip 002abf9c sp bfdb7a70 error 6 in libperl.so[101000+257000] ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=676128&aid=2113169&group_id=116817 |
