The -r flag to strace allegedly does that, but I've not tried it yet. > 2) Is there > a way to query the system for the path of a fd from another process... Try this: #pidof pan 13522 #ls -l /proc/13522/fd total 0 lrwx------ 1 wa1ter users 64 2008-08-06 17:34 0 -> /dev/pts/3 lrwx------ 1 wa1ter users 64 2008-08-06 17:34 1 -> /dev/pts/3 lrwx------ 1 wa1ter users 64 2008-08-06 17:34 10 -> socket:[317753] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 11 -> socket:[317765] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 12 -> socket:[317767] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 13 -> socket:[317777] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 14 -> socket:[317782] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 15 -> socket:[317785] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 16 -> socket:[317792] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 17 -> socket:[317794] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 18 -> socket:[317795] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 2 -> /dev/pts/3 lrwx------ 1 wa1ter users 64 2008-08-06 17:34 3 -> socket:[313872] lr-x------ 1 wa1ter users 64 2008-08-06 17:34 4 -> pipe:[313874] l-wx------ 1 wa1ter users 64 2008-08-06 17:34 5 -> pipe:[313874] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 6 -> socket:[313920] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 7 -> socket:[317855] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 8 -> socket:[317756] lrwx------ 1 wa1ter users 64 2008-08-06 17:34 9 -> socket:[317764] I'm downloading bazillions of headers right now and all pan is talking to is sockets, no files. (BTW, fd 3 is reading mouse input.) BTW, here is my event log during the header download: Wed Aug 6 17:34:42 2008 - Loaded 53397 articles for <======= NOTE "alt.binaries.cd.image" in 11.3 seconds (4733 per second) Wed Aug 6 17:34:46 2008 - Added 1 articles to alt.binaries.cd.image.

I don't know what the 53397 articles in 11.3 seconds is about, but grepping thru pan's source code should tell us that -- tomorrow ;o) _______________________________________________ Pan-users mailing list Pan-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/pan-users
