OT: netscape 4/libc6/128-bit encryption
I know this question belongs properly in the netscape forums, but they seem pretty MS-Windows oriented. I'm guessing many of you have had a similar problem already (though I haven't seen anything recently on the lists.) Netscape 4.06 with 128-bit encryption is only available from the netscape web site after filling out forms giving your address, etc. Unfortunately it's linked with libc5; for various reasons I won't go into here this is unsatisfactory for us. It is possible to get 4.06 linked with libc6 from the ftp site; however, this is the export version which only has 40-bit encryption, and which we'd prefer not to be stuck with. Has anyone succeeded in downloading a 4.x/non-export release linked with libc6?
pvm package strangeness
This one's really got me stumped. Here's the scenario: Under slink/i386: - user runs binaries linked to libpvm3 - suddently (as of this week), any calls made to that library result in a segfault - even the example program provided with pvm do this - this occurs on several different machines, none of which have undergone changes that I'm aware of - reinstalling the package doesn't change anything The wrinkle is that downloading building the package myself using apt-get source -b pvm results in a package that, when installed, *does* work. It's the fact that things were working before which really confuses me...

Try CMU's cyrus; there's no debian package yet, but it's a superb server, and actually the basis for many excellent commercial servers. It stores mail messages in individual files, but not in a mailreader-supported format, so it won't allow you to keep a normal mail spool; clients must use POP or IMAP. See http://andrew2.andrew.cmu.edu/cyrus/index.html, which is unfortunately very out of date. Use the latest version (1.6.13), not the one listed on the page. Available at ftp://ftp.andrew.cmu.edu/pub/cyrus-mail.
closed bugs
Is there any way of getting complete bug reports (including those that have been closed) for a particular packages? I think I've found a bug in librx1g/regexec(), and was hoping to verify that.

Maybe there's a process with an open filehandle somewhere? Try
fuser -m /
to get a list of pids that are using root... perhaps one of them has a
big open file that you've removed, but whose space won't be reclaimed
until the process closes the filehandle.

Nor I... the only solution that comes to mind which doesn't involve programming something yourself is to switch to Mutt and drop fetchmail. Mutt doesn't support the options you seek directly, but it would allow you to set up macros that would do it for you. The action of opening the folder in question can be hooked to trigger the macro, so it would happen automatically. If you're willing to contemplate changing mailreaders I'll show you how to do it. > Configuration #3 > -- > I can further configure Eudora to delete read mail if I have > deleted that mail from the local trash box. > > I don't know of any way to get fetchmail to do this either. This would be trickier I think. Can you describe the mechanism in more detail (that is, the sequence of events leading up to mail being deleted on the server)?

McGill's pretty cheap compared to American universities, and its CS department is very open to free software. In fact, we've currently got something on the order of 100 Debian machines and only about 25 NT machines (the latter are strictly for the introductory courses and for faculty use.) Our larger servers run Solaris, most of the others are Debian, and FreeBSD is making inroads.
intermittent mountd problems
I'm going crazy here. There are two 2.0.38 slink machines serving NFS at our site, and every few weeks they stop allowing new mounts. I've searched exhaustively on the net without finding anything, and I was hoping maybe someone here had encountered a similar problem. Incidently, we had the same problem with a 2.0.36 kernel, and it always coincided with syslog messages flagging possible syn attacks. We thought that maybe it was a kernel bug, so upgraded and disabled the syn cookie option, which seemed to fix the problem at the time, but apparently hasn't. We can go for weeks without a single blip, and then spend days with NFS more down than up. Our users are understandably upset, and so are we. I'm having trouble keeping the FreeBSD bigots at bay. Problem description: - the NFS daemons (nfsd and mountd) don't die or freeze, but don't service requests; thus in debug mode mountd gives Feb 15 15:36:05 square mountd[432]: mnt [1 100/2/15 15:36:05 yoda.cnd.mcgill.ca 0.0+0,10] Feb 15 15:36:05 square mountd[432]: ^I/exports/u0 Feb 15 15:36:05 square mountd[432]: NFS mount of /exports/u0 attempted from 132.206.114.131 and sometimes even prints a line claiming success, but on the client the mount always returns "RPC: Timed out" while the problem is ongoing - usually it'll be just mountd that screws up, and already mounted filesystems are fine; it's unclear to me whether nfsd also gets hosed by itself, or if it happens as a result of trying to get mountd running again; I suspect the latter - sometimes restarting nfs-server helps; often we actually have to reboot to get a quick fix, but even that doesn't last long on some days, and sometimes it doesn't even seem to help at all; sometimes multiple kill/restart sequences seem to work, though why that should be I don't know I've tried leaving long straces running on mountd, I've tried sniffing the network to see if we're being hurt by something else on the network, and can't see anything noteworthy. The only oddity I've noticed recently is that an rpcinfo -p of the server lists two unnamed services I can't track down (any theories are welcome - I'm pretty ignorant of rpc stuff generally): 6001000691 udp773 6001000691 tcp775 Also, this may be incidental, but the behaviour occurs much less commonly on the server we have named gloom, which is on a different network and subject to different traffic. Fixing it on gloom is usually more pressing and more lasting, so I haven't had a chance to investigate as thoroughly there. --- p.s. We wanted to try running nfsd/mountd from inetd to see if that helped matters in the short term, but inetd seemed to only be willing to register the udp or the tcp servers, not both. Is this a known problem? Lines used were from the manpages, i.e. mount/1-2 dgram rpc/udp wait root /usr/sbin/rpc.mountd rpc.mountd mount/1-2 stream rpc/tcp wait root /usr/sbin/rpc.mountd rpc.mountd nfs/2 dgram rpc/udp wait root /usr/sbin/rpc.nfsd rpc.nfsd nfs/2 stream rpc/tcp wait root /usr/sbin/rpc.nfsd rpc.nfsd
/etc/adjtime does what?
I can't find a reference to it anywhere, and since it comes with base-files it's unclear what program uses it. I'm just curious.
reading an random block from a floppy
I'd like to do the equivalent of dd if=/dev/fd0 bs=1k skip=1439 without having to read through the 1439 blocks in question; that is, to not treat the floppy as a sequential device. This is running out of a floppy boot image (not Debian's, my own) so I don't have perl available, though I do have awk. I'd prefer not to have to write a C hack for it, as that's my last resort; I know it would be easy, I just don't want to re-invent the wheel. Any suggestions of tools I could use?

Me too. Never mind folks, I bit the bullet and wrote the code - figured it would be good practice for my rusty C, even if it is just 50 lines worth of practice. I guess I just didn't like the idea of wasting a few K of my bootdisk on such a special-purpose tool, but so be it. Oh well, if anyone else is ever looking for such a tool on debian-user they'll know who to email. :)
logged boot sequence a la HP-UX
I'm wondering if anyone knows of work being done to make sysvinit capable of logging the output of the rc scripts? HP-UX does this very nicely, such that instead of seeing what the script writes on stdout you get a curses-style table of scripts and their results, e.g. Starting NIS server OK Starting NFS server *FAIL* I don't really think it's worth having as fancy a display as HP-UX does, since I wouldn't want my boot sequence to fail just because curses or slang or whatever broke, but you could get almost as nice a readout without. And you could still have the script output written to rc.log, which is what I'm really looking for.

Check out linux-hacker.net/i-opener. It's i386-based and Linux runs on it, so there shouldn't be any reason why Debian wouldn't.

I'm pretty sure 2.2.14 supports it, and I think some earlier ones. I haven't tried it myself, but my colleague discovered it by accident, and I know he hasn't built any development kernels.
dpkg --set-selections failing silently
This is with slink's dpkg. For reasons I don't understand, some packages don't get set by --set-selections and no explanation is given. Currently I've only noticed this with libpng2-dev, librx1g-dev and zlib1g-dev. Example: flanders:/usr/local# dpkg --get-selections |grep png libpng0ginstall libpng2 install pnmtopnginstall flanders:/usr/local# echo libpng2-dev install |dpkg --set-selections flanders:/usr/local# dpkg --get-selections |grep png libpng0ginstall libpng2 install pnmtopnginstall I've had similar problems when missing dependancies were at issue, but that doesn't seem to be the case here: flanders:/usr/local# apt-get install -d libpng2-dev Reading Package Lists... Done Building Dependency Tree... Done The following extra packages will be installed: zlib1g-dev The following NEW packages will be installed: libpng2-dev zlib1g-dev 0 packages upgraded, 2 newly installed, 0 to remove and 21 not upgraded. 2 packages not fully installed or removed. Need to get 0B/264kB of archives. After unpacking 829kB will be used. Do you want to continue? [Y/n]

But then why wasn't apt-get trying to install libc6-dev?
NIS issues
I keep getting mail on some slink machines from cron jobs, e.g. the "test -f /proc/modules && /sbin/rmmod -a" one. They contain the single line: yp_all: clnt_call: RPC: Unable to receive; errno = Connection reset by peer Anyone know what this signifies, how NIS gets involved in such a simple cronjob, and what I can do about it?

I gave that a try, but it doesn't seem to have helped. It looks like it's a question of our network being saturated during the execution of certain cronjobs. Time to buy that new switch, I guess. Thanks very much for your informative reply.

How do you prevent people from cracking passwords via your web page? I'm still looking for a secure way to accept passwords via HTML - even with SSL, from what I understand the available authentication stuff isn't suitable for use with /etc/passwd. It's too easy for someone to write a brute-force password scanner that won't leave traces.
