I def know what you mean with the Inet not being friendly anymore...I'm trying to explain to clients and co-workers alike that you can get an virus just by browsing a website...when Is M$ gonna patch that horrible browswer of theirs anyway?!!?!? So firewall is step 1. that I'm prob gonna test in house first, then expose it (complete with jail ;) ) -----Original Message----- From: Bob George [mailto:mailings02@ttlexceeded.com] Sent: Wednesday, March 31, 2004 2:52 PM To: wlug(a)mail.wlug.org Subject: [Wlug] Re: Good HowTo Martin, Eric wrote: > A large part of it is the learning, that's one of the things that got > me into comptuers in the first place.

That's a great approach, but do appreciate that in making some early mistakes, you can easily wind up with your system used to relay spam en-masse, or worse. I would recommend a slow and thorough approach, along with a fail-back option if something doesn't work as expected. Get the firewall working and tested as step 1. Have someone knowledgeable help with testing as you go. Unfortunately, the 'net has become a dangerous place for learning these days, and mistakes are quickly exploited. Or you could simply never make mistakes. :) - Bob _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Well, depending on your ISP 'situation', something like this might be nice: http://www.dyndns.org/services/pricing/index.html#mailhop I use dyndns' backup MX service, in case my connection goes down. They spool for up to 10 days, I believe. -- Josh Huber _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

A large part of it is the learning, that's one of the things that got me into comptuers in the first place. I know it sounds crazy, but I want to deal with the headaches of a mailserver, and possibly 2 DNS servers if I can run them.

The first question is: will your provider allow incoming smtp to your address? If so, you can set up MX pointers to your server... unless it's dynamic. In which case, you could set up with one of the dynamic dns providers, and update it with a short TTL. In which case, everything shulud work, although some systems will reject (RBL) mail originating from your address simply because it IS dynamic. Back in Phoenix, I was set up (with Cox as my provider) with a server at the house directly accepting mail from outside. It was great fun, but due to the worm/virus outbreaks, and various threats from the community at large, they began blocking inbound smtp, and eventually outbound as well. While this was certainly aggravating at the time, and I was annoyed they didn't bother to NOTIFY me of this change, in hindsight it's probalby just as well. I wound up going with a $2/mo. offsite hosting outfit, and have to say my aggravation levels are greatly reduced (not to mention I can down my server and not worry about losing stuff... a real advantage while moving last summer.) It's also nice now that I'm experiencing the not-quite-so-steady power in my new home area. Mail for my domains goes to the hosted server (my MX), and I pull it down at regular (5 min.) intervals using fetchmail via POP3. I run postfix locally, but relay through my provider's (charter) smtp server for outbound to avoid sudden surprises if ToS changes. I've got accounts on the hosted server for my users (family), plus a "wildcard" that I can use to break things out locally via aliases. It's not as sexy as having incoming mail handled directly, but mail for my domains "is delivered to my server" for local reading via POP/IMAP, and I do have control over the local outbound (smtp). I don't have spammers knocking at my server constantly, and I have to admit I don't miss the headaches of an exposed server (though the learning was fun). I'm not sure if that's what you had in mind, but it does work well. > I have Postfix in mind, I've heard it's pretty easy but I'm obviously > not set on it. I used postfix throughout, and found it quite easy to set up and administer. Handling multiple domains locally was no big deal, jsut a matter of setting the "mydestination" option. Again, specifics may vary depending on what your provider allows/requires. > I'd also like to include spamassassin, and antivirus (clamav > probaly...) I do run spamassassin via local delivery, but obviously the stuff's made it onto my server by then. I don't run any MTA-level blocking, due to the setup described above. It does keep the crud out of my family's inboxen though (and quite deftly, I might add.) I also chain bogofilter and spamprobe, experimenting with variations on bayes. I'm on the spamassassin list, and there ways to get MTA-level integration, if you desire. I'm running several anti-virus (3 - bitdefender, f-prot and clamav) in line via procmail on delivery. Each detects some the others miss (depending on the hour.) Again, this could be integrated at a higher level. You might check out amavis or mailscanner. I've got anomy sanitizer as a 3rd level of defense, stripping off active content and defanging (web bugs and the like), for selected accounts. I set this up all as discrete steps, and had no real headaches. The documentation for each package (postfix, fetchmail, procmail, spamassassin, clamav) was sufficient. I run my own linux firewall, but I can understand why some folks prefer to by an appliance. I host my mail server off-site, but have done the "studly mail admin" bit as well. Just a question of trade-offs for a home/hobby system, and how much time you want to spend on it. - Bob _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

That's another good point about Charter...most of the tech support people are everyday people with a manual in front of them that has a table with 2 cols: Customer reports problem :: Solution. I had more dynamic solutions when I was 10 than these guys have. Also, how hard is it to setup a linux router? I've been meaning to make a DMZ, just have to get familiar with iptables...

It just means that they won't support it. Charter will add $30/mo I believe....Verizon Does PPoE, get get ready to recompile your kernel if you aren't using a router (which you are, so it doesn't matter). Once you have a router plugged in, your internet connection becomes just a regular lan, and TCP/IP takes over, not Verizon or Charter... -----Original Message----- From: Gregory Avedissian [mailto:avedis@rcn.com] Sent: Wednesday, March 31, 2004 12:36 PM To: wlug(a)mail.wlug.org Subject: [Wlug] High-speed access questions It seems like most of the providers say that you need windows or mac to use their DSL or cable internet. Does this just mean they won't offer tech support for linux, or does it mean that it won't work? I'm planning on using a router and having two computers connected. Has anyone had luck with linux and Verizon DSL? They're down to $35/month, and they give you the modem. Anyone know of better deals? Thanks.

RedHat 9 Network Problem
by Joel Young 31 Mar '04

31 Mar '04

I just replaced Windows XP with RedHat 9 on one of my machines at home. My problem is that I can't connect to the network. If I specify DHCP and then try to connect I don't get any responses from my DHCP server and 'eth0' won't activate. If I specify a static IP address (i.e. 192.168.1.2) then 'eth0' will activate but I still can't get out on the network, event to ping. My network configuration consists of a Netgear 10/100 Wireless Router connected to a Cable Modem, with a Linksys Router/Switch to the Netgear Router to expand my ports. I've been running fine from all my XP Desktops through this configuration using DHCP. Any ideas would be appreciated.

Anybody have good suggestions for a good beginners linux book? I teach Adult Education classes for Worcester, and I'm thinking of a Linux class target towards small business owners (figure they'll be the easiest to see the benefits.) Any ideas? Eric Martin

hi, i just wanted to answer your question, and thank you for the meeting the other night. my friend and i attended for the first time. your question: try linux in the workplace by the linux journal press. isbn is 1886411867 it's not the newest (not that old either) but it covers most of the KDE aps from 3.1 -Jonathan Beall p.s.- my friend and i just started a business called JBC Solutions. It's desktop and server linux solutions aimed specifically at the small business owner (Koffice, OOo, Samba, Apache, etc). would you mind keeping me up to date with your class? thankyou. >From: "Martin, Eric" <MartinE(a)worc.k12.ma.us> >Reply-To: Worcester Linux Users Group <wlug(a)mail.wlug.org> >To: Worcester Linux Users Group <wlug(a)mail.wlug.org> >Subject: [Wlug] Good Beginners Book >Date: Thu, 25 Mar 2004 12:57:43 -0500 > >Anybody have good suggestions for a good beginners linux book?
