Re: Inconsistent utx.active?
Hello Vlad, * Vlad Galu d...@dudu.ro, 20120225 00:24: Sigh, you are right. I had UseLogin set to yes in sshd_config. Sorry for the noise and thanks! Even with UseLogin I fail to reproduce it on my system. Even with UseLogin enabled it shouldn't cause utmpx entries to be `leaked'. I'll keep UseLogin enabled on one of my systems from now on to see whether it occurs sporadically. Thanks for reporting the issue. -- Ed Schouten e...@80386.nl WWW: http://80386.nl/ pgp0DE1Ur5bxA.pgp Description: PGP signature
Re: Inconsistent utx.active?
Hi Vlad, Has anyone else noticed erratic bookkeeping by utmpx in RELENG_9? Would you mind explaining to me what you're seeing? It's hard for me to fix bugs if I don't get proper reports. -- Ed Schouten e...@80386.nl WWW: http://80386.nl/ pgpcKCladCJsr.pgp Description: PGP signature
Re: Inconsistent utx.active?
Hi Vlad, * Vlad Galu d...@dudu.ro, 20120224 23:35: Yes, sorry about that. I'm seeing stale (which sometimes turn into duplicate) entries when I log off and on again. The symptom seems to be exacerbated by unclean logouts (such as when my stateful corporate firewall kills my SSH sessions - I don't have keepalives active at either end). In the example below, I'm actually logged on from IP address X.Y.Z.T, the first two entries belong to earlier sessions that have been long gone. The pts is the same, and the command displayed under WHAT is mirrored for all 3 entries. Would you mind pasting the output of `getent utmpx active'?
