Hi, I was wondering if someone can help me configure a cale modem to use in linux. I am on charters network. I have tried myself but it is not working. I setup my ethernet card eth0 this seems to have taken because I can ping localhost. However I cannot ping past it. TIA, Bill __________________________________________________ Do You Yahoo!?

Lexmark z52
by Doctor Orbitz April 12, 2001

April 12, 2001

Has anyone here setup a Lexmark z52 printer in linux? I am having alot of trouble. I set it up according to how I think the documentation tells me to but my printer just gets a post script file, which it obviously doesn't understand. Tech support refuses to help me saying that because I am using Slackware it isn't supported. But Linux is Linux right? Thanks, Orbitz

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
by Terry Yelmene April 8, 2001

April 8, 2001

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)

D-Link, SMC, NetGear and LinkSys all have them for just a hair over $100 provided you're sitting on a Cable or DSL connection. My SMC is web managable and does a lovely job.

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 April 5, 2001

April 5, 2001

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
