Date: Mon, 13 Sep 1993 23:45:28 GMT With all of the furor over SLS and all recently, I have a question as to the differences between all of these new "distributions" going around. You see, when I first found out about Linux, I first just got copies of the kernel and all of the utilities and all. I also got the little readme file that detailed how I was supposed to run fdisk and then mkfs and all that crap. It never did work for me. That's why I was pleased when I found SLS, because it installed itself for me and I was up and running. . Now that there all of these competing distributions out there now, I was curious what the difference between all of them are. The last time I checked the faq, it just mentioned that SLS was a little easier to install than the others of that time. Specifically, what are the perks offered by each of the distributions? -- Joe Emenaker - Sexual Engineer | Our infernal mailer daemon has been quite jemenake@oboe.calpoly.edu | insistent that my signature be limited to just ..or.. @bslab65.calpoly.edu | 4 lines.

Is there a PPP (Point to point) driver/solution for Linux. Here at IU they are putting in a Xyplex terminal server that is going to support PPP and I would like to be able to use it but I'm having no luck finding PPP for linux.

It's me again. ;-) Maybe my last posting (you know it, don't you) was a little to tough, so please let me explain my opinion a little clearer: I thought, these newsgroups are a forum, where people using Linux meet and discuss problems and so on. And, what i can't understand, is how can someone refuse to help because i don't use his preferred distribution of the SAME operating system. And that, and ONLY that, "i refuse to help people plagued by SLS" is what i wanted to call arrogant, NOTHING ELSE !!!!!!! *apologizes for that* And *please* believe me, SLS work 100% for me. It's true, that after installation you've got to fix serveral things, but i never wrote : "it installs perfectly". ;-) So please take my apologizes for misunderstandings (maybe caused by my english), but i still believe it's better to answer "YES, I CAN HELP YOU !"

The only tricky thing is to set up getty in a way that it doesn't check the status of the control line (RING, DTR, DCD, ...). This is done either manually by stty clocal /dev/ttyS?? or by inserting a CLOCAL in /etc/gettydefs in the appropriate line. Note that the newer getty also uses files like /etc/default/getty.ttyS?? for individual settings. Example: /etc/default/getty.ttyS1: # [ put this file in /etc/default/getty. ] # # getty configuration file for a dumb terminal # timeout to disconnect if idle... TIMEOUT=30 # wait for a carraige return before trying to display the /etc/issue WAITFOR=\r Hope this helps, Tom. ========================================================================== Thomas Voss Phone: +49 0241/807893 Institute of Semiconductor Electronics - II Fax: +49 0241/86165 Technical University Aachen Germany -- ========================================================================== Thomas Voss Phone: +49 0241/807893 Institute of Semiconductor Electronics - II Fax: +49 0241/86165 Technical University Aachen Germany ------------------------------ From: mykes@shell.portal.com (Mike Schwartz) Subject: Re: NFS performance Date: Tue, 14 Sep 1993 08:46:57 GMT Enrico Scotoni (scoti@gccs.imp.com) wrote: : > So, linux copies to the sun in 1:08, vs amiga to sun in 13. : > That's what I call a performance problem!

Becker said these routines are pretty easy to implement... He then came up with a suggestion for me - compile up the linux nfsd on the sun and use it instead. Unfortunately, even though I got an nfsd to compile, it didn't work on the sun :( when I invoked nfsd by hand, I got an error message: "Can't make UDP connection" and when I replaced the sun's nfsd with the new one, nfs stopped working altogether...

Well not exactly true. This feature is controlled by the /etc/login.defs file. With it you can select which devices allow root logins. So you could set it to you modem line. Of course it's probably not a good idea. Also even if root logins are not allowed you can su from any valid account. So preventing root logins from the modem does not prevent root access.

You know how to fix the glitches after installation. But other people might not, please keep that in mind. Even though it works 100% for you, ironing out the bugs from a system is not something that many people, especially first-time installers coming from DOS can do. I feel that this has taken many possible users from linux, because of the things they should fix but have no idea how to begin. >So please take my apologizes for misunderstandings (maybe caused by my >english), but i still believe it's better to answer "YES, I CAN HELP YOU !" For people like the above, I think that the original answer about not helping people plagued by SLS *IS* exactly "YES, I CAN HELP YOU!" It would be a long and tiring attempt to debug someone's SLS system through the net for the helper and helped. It doesn't give one a very good picture of linux, let me tell you. First impressions count. To really impress someone, the system has to install and work flawlessly, without fixing several things at the outset. And do we want linux to impress people or not?

Uncomment and edit the lines in /etc/rc.d/rc.inet1. When you reboot the net config is set up properly. Patrick has done a nice job with net setup.
