Most of us make pppd setuid root, and readable & executable only by group and owner; make the group something like 'ppp' and add to it users who you trust to run pppd, including the dialin account that you have set up. If you need step-by-step instructions on how to do that, I suggest checking out a beginning unix book because you will learn much more than a cookbook answer. --- Andy Tefft - new, expanded .sig - teffta@erie.ge.com ------------------------------ From: teffta@erie.ge.com (Andrew R.

Just define a static default route to your router.

Maybe it's not necessary for you; let's not question the motivation of someone who clearly knows what he wants to accomplish :-). I suspect that all people su to their individual uid 0 account, and yes separate root passwords are quite a good idea when there are multiple root users, whether they change frequently or not. --- Andy Tefft - new, expanded .sig - teffta@erie.ge.com ------------------------------ From: herbert@greathan.apana.org.au (Herbert Xu) Subject: Re: about wtmp Date: 6 Sep 1994 22:19:48 +1000 Daniel Tran (dtran@emelnitz.ucla.edu) wrote: : In article <199409040350.XAA16276@gasa.physics.buffalo.edu> XiaoFei Wang writes: : >How do I use wtmp?

However, being a new user I have a problem when I run X-windows in linux then bringing up 1 xterm for compiling. During compiling of X windows programmes: I get this "virtual memory exhausted error" from the system after using the gnu compiler. I have 8 Meg of RAM and a 12 MB swap space. That should be suffice to run at least 5-6 xterms. Now I know that if I installed SCO ODT 2.0 on my machine at home I would be able to bring up 1-2 xterms and that would be the max. I know that linux should be able to handle alot more X terms because it a bit more lean and mean.

I am running Slackware 2.0 with kernel 1.1.42. Here are my problems: 1 A while back in kernel compilation configureation, one could specify whether to boot up with Numlocks on. I liked this since I could have my BIOS default to no ( for DOS/my wife ) and have Linux boot with it on (my preference). What ever happened to this feature ? Was it dropped for some technical reason, or did somebody just not like it. I would be willing to work on a patch to include this feature again it someone would kindly give me some pointers as to where to look int the kernel source tree for where to make the mods. 2 It seems xconsole is next to worthles. I cannot get it to pick up the console messages coming to me on a psuedoterm. Hence, no error messages, no talk announcements etc. The only thing I HAVE gotten to work it echo Hello > /dev/console . I can't even get that with xterm -C. This is both with xdm and xinit(startx). Any clues on what/ how to fix this ? BTW I am still looking for the source to xconsole. I you know where it is email me. I should find it in a day or so as I get the time. ------------------------------ From: bwillems@lynx.dac.neu.edu (Balam Willemsen) Subject: /etc/issue and incoming telnet Date: 6 Sep 1994 11:49:35 -0400 This is probably a FAQ, but I didn't find the answer quickly elsewhere... I have a box (no not this one) which will go "on the net" soon, and I want a message to appear before the login: prompt on incoming telnet sessions. I was under the impression that /etc/issue was the appropriate file, but it only affects the virtual consoles on the system not telnet sessions from the net!?! /etc/motd is displayed only after the person has already logged in, so it is useless for my purpose. It's a brand new installation of Slackware 2.0 with only the a and n series of disks loaded in case that makes a difference.... Balam -- Balam A.
