RE: [techtalk] login restriction
in inetd.conf - turn off all services you don't want. This includes rlogin, rtelnet, and telnet. in /etc/passwd set the last to /dev/null use tcpwrappers on all incoming services you left open (via inetd.conf). Do not run any stand alone servers you don't trust. That is all. Bill On Fri, 7 Jul 2000 14:12:06 -0400 , Fan, Laurel wrote: > Susannah D.

[techtalk] Problems with two ethernet cards
Here is the situation. I am building a firewall with an old 486 33 Mhz. Motherboard = ??? ram = 20 M hd = 800 M 2 3com 3c509 ethernet cards 1 56 k zircon internal modem The problem. The network hangs. if one ethernet card is started I can ping the test machine easily. When the second is turned on everything freezes. Things to know: interrupts eth0 - 10 eth1 - 11 both use ioport 0300 - 030f ( I think this is the problem) Questions Has anyone seen this before? Is there a fix? For the record I haven't gone through the howto networking on this yet but plan to download the most recent. Any help would be appriciated Thanks, Bill ___ Get 100% FREE email for life from Excite Canada Visit http://mail.excite.ca ___ techtalk mailing list [EMAIL PROTECTED] http://www.linux.org.uk/mailman/listinfo/techtalk

Re: [techtalk] HA/Virtual Server solutions?
Hi, If they have their solution already set up, your best bet is to write a script that monitors the health of all the servers, and returns the information to the machine that runs the DNS. Once you have this information, you can write another script that takes servers off the DNS round robin if it goes above some threshold. Some edge conditions have to be dealt with, example, minimum numbers on line all the time. Generally speaking, round robin algorithms are best for tasks that are all similar in nature (cpu usage, memory usage, time to completion) so I don't think you'll get anything by changing the algorithm. What you need to do is check for over use of one server and put that temporily off line until it finishes. I don't know if there are products out there that can do the job, but perl has all the requirements to allow you to do it yourself.

Re: [techtalk] Clustering anyone?
try www.beowulf.org it has links to every major cluster. I did exactly what you are trying with my old hardware. Before going down any route ask yourself why? I found after building one that it was a cool experience but I really didn't have a use for a cluster other than using all the old hardware in the basement.

Re: [techtalk] Linux and UNIX
Fire off the questions. The worst we can say is that it isn't applicable to linux. Most of us on this list are familar with more than one *nix anyway. I suggest you try to mention the *nix in the question because there is slight differences between the flavours.

Re: [techtalk] uptimes ... ;)
To answer your question. There is no way to upgrade a kernel without rebooting the machine. My firewall has been up 127 days. Its not connected to a UPS though and the last three times it went down was a power failure. I use the power failures (about once every four months) as excuses to do maintenance on the firewall. The longest uptime I have seen was a 1.2.13 kernel (Slackware) 486 processor being used as a DNS server. It started up in 1996 and was retired in Jan 2000 when the power supply went. It was two months shy of 4 years. Bill On Sun, 27 May 2001 15:17:19 +0200, Almut Behrens wrote: > On Sun, May 27, 2001 at 11:09:13AM +0100, James Sutherland wrote: > > > > LOL!
