Confessions of Network Administator: I did 3 things wrong that caused all my problems with PPP and IP Forwarding: 1. DNS/BIND mismatch between my primary server, and my providers server My Internet Provider runs a secondary name server for my domain, and I made changes to my primary DNS tables (including re-assigning the IP of my DOS box)... BUT I FORGOT TO CHANGE THE SERIAL NUMBER IN THE DNS TABLES. The serial number is how secondary servers determine that DNS needs to update... So the two servers had different IP addresses for the same host name... OOOPPPS! 2. DOS TCPIP Routing MisConfiguration Netmanage Chameleon has two separate configurations for routing... the Default Route, and a Routing Table... I had set up an entry in the routing table for my Net Provider that pointed to a router that was available on the old network that I was connected to.. and that entry over-rode the Default Route that pointed to the correct router (took me 4 days to find that one) 3. Gratituously updating Linux versions My initial response to this problem was to blame Linux 1.0 and to attempt to install a later rev of the system (1.1.49 to be exact). This ofcourse created all sorts of additional problems requiring the installation of updated applications and utilities, which I thouroughly botched in my haste to get the system working as a router.... Since I found the other problems, and did a complete re-install of 1.0.... everything has worked fine... Advice to the Wannabe Network Administrator: Erasing and application and doing a clean install may not be a bad idea. All of the configuration may look right.. but some leftover trash may be spoiling your whole day. Request to the Linux Developers: I had a *ell of a time figuring out what patches and utilities went together to make a fully updated version of the system... Grouping the Patch files with the utilities required to accomodate the update would really help. Other than that... KUDOS TO YOU ALL... Linux is the best system I've worked with since I started working with MicroPort and Venix 6 years ago.. It certainly beats even the latest release of UnixWare in terms of ease of installation and loads of applications and utilities right outa the box... Before I shoot myself in the foot again.....

The AC3200 driver is for the Ansel Communications EISA ethercard based on a shared memory 8390. It's unrelated to the NE3200, which will probably never have a Linux driver. Both are unrelated to the Intel EtherExpress32. I don't have any documentation on the EE32 (or an EISA machine to develop a driver on), but Intel might release it if you ask them. -- Donald Becker becker@cesdis.gsfc.nasa.gov USRA-CESDIS, Center of Excellence in Space Data and Information Sciences.

Date: 24 Sep 1994 09:36:14 GMT How to duplicate more boot floppy from one existing floppy? I'm facing some serious trouble when installing linux on a Pentium with 1G HD; linux is within the first 300meg, so I don't think the 1024 cylinder problem should affect me. But the new installation refused to boot ("partition table error"); the floppy created during the installation refused to boot too. The only thing got the system going was a floppy from a previous installation on a 486. Now since that disk was reated only for backup purpose, I'd prefer to make a seperate one for booting the Pentium box. Any thoughts on how to copy a floppy containing kernel image?

Hmm ... I'm not up on sizes for modem buffers (I was trapped in a hardware design project for a long time and only recently surfaced for air. :) ), but a 24x80 line screen is about 2k ... just how large a buffer are we talking about, anyway? If it is on the order of kbytes, then there is another solution. 99 times out of a 100, a user is using either vt100/ansi emulation. I'm not entirely sure, because this isn't really my field, but I believe there is at least on vt100 code that will cause the user's terminal to respond with some sort of transmission [I think this is how automatic detection is possible, correct me if that's wrong, please.]. You could send your banner, immediately followed by such a code, and calculate the time elapsed between when you began sending the banner and when you got the response. This would give you a decent estimate of the lapsed time. This would have some drawbacks, namely a reduction in portability for applications that used terminals that didn't have such a code (and you would definitely want to be checking the TERM environment variable to make sure the code you send is the correct one for the terminal), and the fact that users of those terminal [emulators] wouldn't get estimates, but I think that anyone who's satisfied with a dumb terminal is probably not going to complain much (if they even have download capability). ------------------------------ From: mzill@saturn.RoBIN.de (Michael Zill) Subject: File system check Date: Thu, 22 Sep 1994 21:11:29 GMT Hello, I post for a friend who hasn't access to the net.
