Last day when one of ours logged in, the following message appeared: panic: kernel trap (ignored) Could somebody explain when the system prints out this message? Maybe that could help us to find finally the reason of our problems. Additionally, we get this "failed" message at every boot (But WHAT failed???)

Date: 1 Sep 1994 14:41:41 GMT Hi ! Does anybody know when the new dosemu is available ? I'm just asking, because at this moment we're using Kernel 1.1.25 with dosemu0.52 and we want to upgrade to the newest kernels, but dosemu isn't running with these kernels. I've read that this is a bug in dosemu [ perhaps not really a bug ] and that the new one will work with the newest kernels. So I kept looking at sunsite and tsx11 for the least few weeks but no new dosemu was there. Does anybody know, where to look, to find the most up-to-date Version of dosemu ?

I can not remembered where I got that file because it has been a while. I tried the sunsite, but it seems not there. I can only find the generic one for Diamond, and I can not make it to display in 1024x768 mode. Can anyone who has this file send me a copy or tell me where I can find this file?

I am able to ftp, telnet, ... just fine through the connection. I have a httpd server setup to serve documents to Mosaic users. When I access the server locally, all is ok. Also, access from a remote Sun and PC with winsock works. However, access from three other locations gives the error "Socket has been reset". I have run on two different httpd servers, and their logs say that all is ok. The only thing in common is that all of the errors have shown up on PC's (but not all PC's). I don't believe it is the server. The PC's are all running WinMosaic 2.0. Does anyone know of a protocol or kernel anomaly that may be causing my problems? I am REALLY pulling hair over this one.

Date: Thu, 1 Sep 1994 18:39:37 GMT If I'm not mistaken, gzip only compresses 1 file. In other words, if you have a group of files, gzip will only zip one of the files. TAR's functionality is very different from GZIP, where gzip is a compression product, TAR's function is to combine many files (and in different trees) into one file. So your question is really moot, as tar and gzip are really different things entirely. If you have many files to zip, you should use TAR to combine them into one file, and then use gzip to zip the resulting file.

This problem lets any user on the Internet gain access to file systems which can be mounted on the local host. Apparently (from discussions on comp.security.unix) it is being actively exploited. There are two possible fixes to this problem: - Install a fixed portmapper, which is now available from sunsite.unc.edu, and mirrors. For the LSM, see below. - As an emergency fix, make sure that it's impossible to mount the NFS exported directories locally; you'll need to edit /etc/exports for this. Try # mount localhost:/exported/directory /mnt and # mount yourhostname:/exported/directory /mnt to see wether you're vulnerable. For secrity purposes, it is best to restrict exporting NFS filesystems to exactly specified hosts you trust, even if it's readonly. Also note that there's a bug in all libc versions up to 4.5.26 (at least) which throws the portmapper into a forking loop under some conditions. To avoid this, you'll need to use one of the newer kernels with the CONFIG_I_AM_A_BROKEN_BSD_WEENIE option, or apply the (binary) patch to libc 4.5. 26 contained in portmap_3_rpcfix.shar.gz (to be found in sunsite's Incoming). Begin3 Title: portmap Version: 3 Entered-date: 1994-08-31 Description: This is a replacement portmap to fix some security holes in the original protocol. Don't install any of the "old" portmap versions. It also features access control to the portmapper via /etc/hosts.allow and /etc/hosts.deny. The *shar files contain source; apply portmap_3.patch and compile. You'll also need the libwrap.a from the tcp_wrappers package. To install the binaries, for which you need libc >= 4.5.26, copy portmap_3_bin.tar.gz to /tmp, then do (as root) # cd / # gzip -c -d /tmp/portmap_3_bin.tar.gz Keywords: NFS portmap security patch Author: Wietse Venema (wietse@wzv.win.tue.nl) Maintained-by: Thomas Koenig (Thomas.Koenig@ciw.uni-karlsruhe.de) Primary-site: sunsite.unc.edu /pub/Linux/network/daemons/ 24604 portmap_3_bin.tar.gz 30737 portmap_3.shar.Z 1738 portmap_3.BLURB 1932 portmap_3.lsm 103443 tcp_wrappers_6.3.shar.Z 1230 portmap_3.patch 2528 portmap_3_rpcfix.shar.gz Alternate-site: tsx-11.mit.edu /pub/linux/sources/sbin 24604 /pub/linux/binaries/sbin/portmap_3_bin.tar.gz 30737 portmap_3.shar.Z 1738 portmap_3.BLURB 1932 portmap_3.lsm 103443 tcp_wrappers_6.3.shar.Z 1230 pormtap_3.patch 2528 portmap_3_rpcfix.shar.gz Original-site: ftp.win.tue.nl /pub/security/ 1738 portmap_3.BLURB 30373 portmap_3.shar.Z 103443 tcp_wrappers_6.3.shar.Z Platform: Linux Copying-policy: BSD-Style End -- Thomas Koenig, Thomas.Koenig@ciw.uni-karlsruhe.de, ig25@dkauni2.bitnet.

Jagadeesh> But who knows! That was true with term 1.X versions. Term 2.X supports connectionless protocals. However, NFS requires binding to a port < 1024 on a machine that is connected with a networking protocal supported by the kerenel. So for right now, NFS still won't work over term. I've heard rummors that the PCNFS protocal does not have this restriction, but I've yet to see a free PCNFS driver. So at present I can't test this assertion. If anyone knows of a free PCNFS driver, please send me a reference where I can get the source code, and I'll try to get term 2.1 to support it. As a secondary alternative, someone can try to write a driver equivlent to Ange-ftp on the remote machine and NFS on the local machine. However, that would be a rather major project that I'm not prepared to tackle yet.

You can get the same effect by using the GNU tar -z option. gzip -r recursively gzips files: it does not create a single file. >I'm looking for the most robust method to archive groups >of files.

Could be, but... I think the problem occured when I moved to a new version of Slackware, trying to keep all the /etc stuff as is, and changing out the binaries from underneath. Probably a dangerous move at best. Thus I think we had your crond running from Vixies' config files. Pure recipe for disaster. Still, by way of suggestion, READMEs are great but I prefer man pages, as they tend to stick around after the source code has been compiled, installed and deleted. Your man page explained the options pretty well, but the above suggestion in the man page would have been nice. Just a thought. ;^) -- W.
