That you got messed up is your own fault. Sad but true. The very first pages of the NET-2-HOWTO explain how to get the NET-2-Software you need to run the NET-2 stuff on the user's end. As it is in UNIX-land: there is a kernel-side and user's side. These few pages direct you to get the net-ext*, net-std*, net-base* packages (don't know the names excactly any more) from tsx-11 or whereever. Follwoing the instructions, you'll find yourself having /etc/rc.d/rc.inet[12], the symbolic links to /conf and so on.

If that isn't your problem, you must be saying you have 32 meg, and only 16 is showing up in linux, in which case you need to recompile your kernel to use memory above 16M (though I thought SLS did that automatically). -- Eric J.

Do you have 32Mb of RAM but Linux is only recognising 16? In this case, recompile the kernel with the option to allow extra memory, and try that. If you are saying "why have I only got 1172Kb free when I'm doing nothing" then you have been caught in the great memory coverup. Linux is a clever system that allocates memory to the disk buffer on demand. The free output shows that 10Mb of the memory is currently assigned to this. As your program load increases memory will be dropped from the buffer and given back to program use, and when the program load drops the spare memory can be reallocate to the buffer. There is one downside to this caching system: when memory is needed for programs, the buffer needs to shrink, and this can lead to a pause as parts of it are written back to disk. This is one case where a hardware cache can be beneficial! Hope this helps. -- Stephen Harris harris@teaching.physics.ox.ac.uk Opinions are just opinions, and the facts are the facts.

Solution: use another machine on the same network to respond to ARP requests! In my case, I added a public arp entry onto a machine running KA9Q. It's not elegant, but it works. Perhaps I missed something with Linux, but after looking through the kernel source (net-2e alpha 4 for networking) I can't see how Linux would do the ARP reply; it just gets ignored. When proxy ARP is finally added, Ill be ready: I patched the arp program to handle the right flags (maybe I should mail the diffs to FvK). Anyone know when Linux will be able to handle proxy ARP? It seems to be a big feature that's missing, and it is very handy with SLIP connections. jpm -- ___________________________________________________________________________ John Paul Morrison | University of British Columbia, Canada | Hey hey!!

Just read the thread about installing the SLS-T-Disks if one wants to install TeX (yes, I know, I'm a little "behind" -> I get the news with modem...). Just a hint. Also! the TeX-Disks from SLS seem to be screwed up. In the archive texbin.tgz (on T1) is a file /usr/Tex/lib/tex/inputs which really shouldn't be in there. It prevents two or three following archives to install correctly 'cause in them there are files which should be extracted to /usr/TeX/lib/tex/ inputs/* (a directory). I solved this just by NOT-installing the archive texbin during "normal" installation of the T-series (btw just grep for pkgtool in the setup script to get an idea how to use it). I installed this package then manually. One more word to pkgtool. I'd really like to see coming up some help lines when it is started without parameters.. (and - please - mentioning the real! switches - not like SLS's sysinstall :->, I just say "series"). bye, Peter E-Mail: pit@gccs.fido.imp.com ------------------------------ Crossposted-To: comp.unix.admin From: c9219517@frey.newcastle.edu.au (Scott Howard) Subject: Re: [Summary] /etc/shutdown by non-root Date: Mon, 20 Sep 1993 05:50:36 GMT Valdis Kletnieks (valdis@black-ice.cc.vt.edu) wrote: : In article <27d35q$bol@agate.berkeley.edu> boss@soda.berkeley.edu (Brion Moss) writes: : >(The script was then setuid root, of course).
