Enabling DMA requires the right driver in the kernel; there is an option for "Generic PCI DMA support" or similar, which might be worth a try if you can't find an exact match for your IDE chipset. What does /proc/pci have to say about your IDE controller? This should tell you which driver to use - then just recompile, reboot, and you have DMA...

At present, the machine is sitting gathering dust as my Alpha can only run GNU/Linux, and it is handling dial up and security duties. (blasphemous that such a powerful machine is doing that and seti, but hey...) OpenBSD firewalling from what I can tell isn't too different. It uses the familiar ipfw to add rules. I think it uses the same ppp as FreeBSD, which handles NAT itself. If you are connected to the internet using anything other than a ppp connection, you should use natd to handle what GNU/Linux people know as ipmasqing. I'd say go for it,(Free|Open)BSD are as if not more capable than GNU/Linux in a majority of circumstances. There are a few differences here and there from the sysadmins perspective, but overall it is a pleasurable experience.

Sorry to bring this up, if you are not running Win 2K ignore this. But I did some more research on the hack attempt on my home server the other day and found some interesting articles on a mailing list. It appears that even if you have installed the security patches--if you install SP2 you have to go back and reinstall those patches for the OS and IIS5 as well. The guy talking about it was able to scan his registry and found that the security patches he installed pre SP2 were removed.

Think about the transfer rates on your disks and CDs and then think about how many machines you're going to have on your LAN. The idea is to keep your network from being the slowest component. In other words, make sure there is enough network bandwidth to hand disk I/O and then you're just as limited by disk I/O rates remotely as you are locally.

[techtalk] Star Office - failed to load necessary component
Hi! I have a problem with Star Office 5.2 on RedHat 7.1. Star Office is being installed with the /net option on a local harddisk. The user's homes get mounted from an HP server via NFS. When a new user executes "soffice" for the first time, the user part of the installation process runs as it should. When the user runs "soffice" for the first time AFTER the user installation, the program fails with the error message "failed to load the necessary components". I have been told that this message means that the file ~/.user52.rdb is corrupted and that deleting this file should fix it. At first, this seemed to work. Star Office started perfectly. But when I tried to start Star Office for the second time, it showed a Basic error message and the icons on the desktop were missing. During the following attempts several other error messages occured. I've also been told that there are problems with the NFS server that can cause these errors to happen. I was able to exclude this possibility because the server machine is the same as for our RedHat 6.2 machines on which Star Office works perfectly. When a user who has already been using Star Office on RedHat 6.2 moves to 7.1 with the configuration files in place Star Office also works on RedHat 7.1. Sun Microsystems only told me to "please make sure you really use Star Office 5.2" ... very funny ... especially if you consider that I wrote that I was using 5.2 serveral times in my message just to make sure they wouldn't give me their "default answer" :-( I really would appreciate any help. Has anyone knowledge of the details of the configuration files Star Office writes to a user's home directory? Or any other hints? I really don't want to have to tell our users to boot Win2K and use MS Office when we upgrade to RedHat 7.1 in the next couple of days :-( Christina -- --- "I smile because I have no idea what's going on." --- ___ techtalk mailing list [EMAIL PROTECTED] http://www.linux.org.uk/mailman/listinfo/techtalk

This is such a newbie question but here goes. Someone in the IRC channel #linuxhelp on undernet told me about a patch I should get for IRC security (kernek patch) and I'm wondering which kernel needs to be upgraded for that.

I've got rc.firewall running on Caldera and the built in Bastille firewall running on Mandrake. Is it preventing me from uploading via DCC in irc because I have two firewalls?

[techtalk] (no subject)
Some other things one might consider are: -turning off ipforwarding entierely and running heavily logged proxies instead -turning off access from TROTW (The Rest Of The World) to things you need through hosts.deny/hosts.access rules -keeping up with bugtraq advisories and new security patches provided for your distro -providing physical security and improving your boundaries against "social engineering" (otherwise known as learning how to keep a secret) -coming up with more effective strategies for dealing with intruders (e.g. honeypots and off-site logging, doing the diffs auto- matically, setting alarm levels appropriately, etc) Perhaps the least effective security measure is throwing your toys on-list. It's uh...*pretty* silly. The closest thing I've seen to an out-of-the-box linux firewall would be the SuSE "minimal install" followed by running the hardsuse script.
