But I did notice in the CVS logs you had effected a repair the very day the PR was logged. Didn't name the PR but did name the symptoms. > It is probably the same section of code, but a different bug > (plus, the PR was for -current whereas you are using -stable) Even more egg on my face as somehow I had HEAD in /usr/src/lib/libalias/ while (I think) everything else was RELENG_4. Not knowing were other such a gaffes may be lurking I'm RELENG_4'ing right now: "cd /usr ; cvs checkout -r RELENG_4 src" Hmm. Looks like natd was also HEAD. Probably did this a year or so ago trying to make passive ftp work thru punch_fw. If anyone has any hints as to how to get started debugging libalias, I'm listening. Building a debuggable natd stymied me when I tried last year. Zeroth step: maybe punch_fw works with ipfw2 for passive ftp? First step: Repeat the problem. I can not passive ftp thru it. IIRC a pair of ipfw rules get written but only non-passive works. Second step: get non-passive working once again and snag a list of the added rules and think about whether one is the right rule for passive. Third step: look deep into natd with gdb and figure out how it got there from here. Will report back success or failure, after I clean up my own mess. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
