slirp chicken and egg problem
Thanks for the suggestions and help, I'm further along, but here's were I'm stuck. If I invoke pptp and connect to it from a windows machine, it makes a connection and then passes control to pppd. On a regular system pppd passes back a data stream that windows recongnizes as coming from pppd and starts communicating. In my case, I can't run pppd because it calls the kernel ppp driver and the kernel does not have it. So I tried to replace pppd with Slirp. Slirp supports ppp. So I tell pptpd to invoke slirp instead of pppd, and include ppp in the slirp options file. I start up pptp, and it waits. I connect from windows and it starts Slirp. Slirp displays a message that it's starting and going into ppp mode. Windows waits for a response from Slirp, as if it were pppd, and Slirp waits for a response from Windows. What do I do?

Summary: chicken and egg (now: backuping DBMSs)
Hi! Thank you Michael Ben-Nes, Frodo, erez, Evgeny Stambulchik, and Mike for you answers. Since all the answers (except for a short thing from Mike) were to linux-il, no summary is needed; Just go to http://plasma-gate.weizmann.ac.il/Linux/maillists/99/10/threads.html and look for the subject "chicken and egg (now: backuping DBMSs)". As you could learn from the thread, it is not the case of black and white. Most (or all) backup packages don't support DBMSs directly, and you must stop/lock the database temporarily before starting the backup. Not to mention incremental backup which is completely im- possible this way (when I wrote about huge databases in my original message, I meant gigabytes of course, and not megabytes). The good news is that most DBMSs have special means for backuping, and you can even export the modifications since a specific time stamp, and to include the exported file in your incremental backup. -- Eli Marmor = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

I know that there are special backup methods for databases. Do you use them? You can run a DB's dump utility (like pg_dump of Postgres) redirecting its output to a file (probably piped through gzip or bzip2). Do it from cron some minutes before the backup is started. Are there special backup tools (e.g. BRU2000, etc.) which support databases and/or even know how to speak with them so backups can be done during normal running of the database? Yes, there are special backup programs that can do it (not BRU, though) - but none that can work with a non-commercial DB, AFAIK. And is there any way to backup databases incrementally? Imagine a database of many megabytes, with some records modified daily; It is not acceptable that the whole database should be copied daily, and there must be a better way... Do you really have _that_ large databases? If we're talking about something within ~ 100MB, I wouldn't bother - backup drives are fast and media are cheap nowadays...

Re: chicken and egg
if you want to do a backup of your entire HD why not using the MSDOS program GHOST ? I think that it supports linux File Systems. and since it copy every bit on your HD then it will not be a problem to recover the info. I recently installed a new card called Magic Card that supports linux quit well. If you want some more info then pls replay me.
