Upgrade to 1.38.4 firmware, I've found it to work the best. It's beta firmware, I got it from the Linksys forum on dslreports.com. http://www.dslreports.com/forum/remark%2c651534%3broot=equip%2c16%3bmode=fla t That forum is an excellent resource for the Linksys hardware. I've never used it, but I'm sure there is a way to set up logging by the router to a file on one of your machines. -----Original Message----- From: Michael Long [mailto:michaellong@charter.net] Sent: Sunday, April 08, 2001 12:14 AM To: wlug(a)mail.wlug.org Subject: Re: [Wlug] Firewalls Your suggestion of an appliance was a magnificent one.

just a bit-o-fun

A year ago last Thursday I was strolling in the zoo When I met a man Who thought he knew the lot. He was laying down the law About the habits of baboons And the number of quills a porcupine has got So I asked him "what's that creature there?" He answered, "Ooh, It's a h'elk" I might have gone on thinking that was true If the animal in question hadn't Put that chap to shame and said "I hain't a h'elk" I'm a Gnu I'm a Gnu I'm a Gnu How do you do? You really ought to k-now w-who's who I'm a Gnu Spelled G-N-U I'm g-not a camel or a kangaroo So let me introduce I'm g-neither man or moose Oh G-no, G-no, G-no I'm a Gnu I had taken furnished lodgings down at Rustington-on-Sea Whence I travelled on to Ashton-under-Lyme And the second night I stayed there I was wakened from a dream Which I'll tell you all about some other time. Among the hunting trophies on the wall above my head Stuffed and mounted was a face I thought I knew; A bison, no it's not a bison An okapi, I don't think it's an okapi Could it be a hartebeest? When I seemed to hear a voice I'm a Gnu I'm a Gnu A g-nother Gnu I wish I could g-nash my teeth at you I'm a Gnu How do you do? You really ought to k-now w-who's who I'm a Gnu Spelled G-N-U Call me bison or okapi and I'll sue G-nor am I in the least like that dreadful hartebeest Oh G-No G-No G-No I'm a Gnu! **************** The source for this definitely wants to remain anonymous- but... I had to share it with you cause, now I@m a Gnu Too! ...(just between us Gnus & Penguins)

There's a great filtering set of procmail rules for this located at: http://www.impsec.org/email-tools/procmail-security.html As long as you have procmail installed and sendmail is configured to use procmail, just drop this stuff in place and you'll instantly start filtering stuff based on content and/or extension. There's a lot of configuration and customization you can do with this thing, and we've found that it works fantastic. We've intercepted the "AnnaKournikova" virus many, many times since it's initial release, and I can't even count the number of other virii I've seen trapped since we installed this.

Filtering attachments via a Sendmail ruleset?
by Dave Coutu 05 Apr '01

05 Apr '01

Hey Guys, Really simple question here... A while back I had asked whether sendmail could filter out mail based on a subject header , and found out that it could. Now I have a situation here at work where we want to filter out attachments, the obvious being .vbs, .exe, basically anything that may contain a virus. We don't run anti-virus software on the mail server that mail is being delivered to, nor on the sendmail relays feeding into it, since they are Solaris boxes and we currently don't have a unix version of Norton lying about. But I believe that we can filter out attachments through a sendmail ruleset, and I am wondering if this is the case. If so, can someone tell me how/where to do it please? Would be very appreciative for any help here! Thanks in advance! Dave

Volunteers needed!

HI gang, I have been asked to be the guest speaker at the Delphi Developers Group meeting in Newton, MA on Monday, April 23rd (http://www.discom.com/delphi). They are interested in Linux due to the recent product announcement of Borland Kylix (http://www.borland.com/kylix). These folks are a group of software developers living in the Windows world. I had planned to prepare a 45 - 60 minute talk, Q/A, and then demonstrate some apps for them, such as: StarOffice Netscape Developer tools and utilities VmWare LILO Desktops - KDE, Gnome, enlightenment, etc. Installation of Linux The above list was suggested to me by their representative as a list of things that would be interesting to their developers group. I am seeking 2 or 3 people would like to volunteer to demo some of these tools at the meeting, and who can provide support for the questions which I can't answer. I'm looking for folks with systems or laptops that they are willing to bring to this meeting for the demos. I would also appreciate a volunteer or two who would be willing to critique my presentation slides before the meeting. You would not need to actually attend the meeting. I'd e-mail the slides to you and request your written feedback. The Delphi group representative will also get a sneak preview. If you are interested in either of these opportunities, please contact me this week if at all possible. Thanks in advance!

I've used AT&T Worldnet with great success - much faster than other dialups... yes, the big mega-ISP but with Linux loving employees who I've spoken with for server / network related issues... how Linux friendly is AT&T??? Visit: http://www.wurd.com/eng/setup/dialers/index.htm There's other Linux stuff on the AT&T WURD site ( http://www.wurd.com ) - but I think this is what you are looking for... OH! if you want to sign up for a Linux account use this method: https://registration.att.net/cgi-bin/inregister Hit the CONTINUE REGISTRATION button - the nine-character Registration Code is not needed... The only way to avoid downloading the Wintel or MAC dialer to setup an AT&T account is through this page... and AT&T customer (tech) support forwarded me a Linux guy (Debian his preference though he runs Mandrake on one of his machines) who gave me the link, only available by direct reference...
