In Linux dual boot systems you can mount the Win98 side drive to read and write using vfat. Question, if you run Win2000 or XP with a NTFS type file system can you still access the drives from the Linux side.

RBL access
by Chuck Homic 06 Apr '02

06 Apr '02

Hey, guys. I'm getting quite a lot of crap email these days, ever since ORBS/ORBL & Co. disappeared, and MAPS went to a fee-based service. (I'm really not planning to pay $200/yr for a single blackhole list.) I was never really crazy about MAPS to begin with, because they tried too hard to be "fair." ;) ORBS was hyper-aggressive, and rocked. (About 80% of my crap email was filtered by ORBS, and I had special pre-RBL filters that extracted mail from friends using bad ISP's with open relays.) Anyway, is anyone using (or know of) a freely-queriable RBL? Although it's fun to upgrade the keyword filter, it would be easier if I only had to do it for exceptions. BTW, for the curious, my daily haul of junk mail varies from 20 to 40 messages. Can anyone beat that? -Chuck

Redundant Mail....
by wlug＠beakerware.net 06 Apr '02

06 Apr '02

I couldn't think of a better way of phrasing it. I'm running Courier for incoming SMTP, POP3, IMAP, and webmail. The mail itself is stored using Maildirs in user's home directory. Short of running something like rsync between my primary box and backup, is their any good way of getting redundancy into the picture here? I already have the backup box setup as a relay in case the primary goes down, but that doesn't make the mail any closer to the user.... -mike

RE: [Wlug] Problems dropping telnet sessions
by Simoncini, Matthew 05 Apr '02

I executed the iptables -L command and got the following output: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I'm not really that familiar with firewalls in linux, but I would assume that iptables is running without rules? I also noticed that it's not one particular host that bumps me out of telnet, but all connections and all hosts. The network folks don't know (or maybe they do) that I'm running linux on the network, but is there a way for them to periodically reset the port I'm using in the data closet? This is really quite interesting to me, so any input is very helpful.

My first two thoughts are: iptables times out your connection for some reason, or the remote side has an autologout value set. Is there a firewall setup on your box? You can do "iptables -L" to find out. As for autologout, I would think this would have affected you before, but it's something to rule out anyway. What shell are you using on the remote machines? If it's a csh variant, run "echo $autologout" and see what it comes back with. If it comes back with a defined non-0 value, that is a likely cause of your problem. Run "set autologout=0" and see if that fixes your problem. -- Randomly Generated Tagline: "Note that if I can get you to \"su and say\" something just by asking, you have a very serious security problem on your system and you should look into it."

Yup, actually I'm doing a presentation on writing a system call for the linux kernel. Speaking of which, I need to get back to working on my presentation...
