I've used the firewall configurer in redhat, both lokkit and the one that comes with redhat. There really isn't much to them, but if no one else knows better than I, I'd be happy to show them. ================================================= | Chuck Haines | AIM: CyberGrex | | ECE Sys Admin | Yahoo: CyberGrex_27 | | GDC Developer | ICQ: 3707881 | ================================================= http://www.linux-xtreme.net -----Original Message----- From: Wes Allen [mailto:wallen@charter.net] Sent: Friday, December 06, 2002 10:27 PM To: wlug(a)mail.wlug.org Subject: Re: [Wlug] Meeting Topic Discussion I just might have to tell my wife I'm coming to this one....

RE: [Wlug] Let's make WLUG meetings better!
by Haines, Charles Allen 07 Dec '02

I would be very interested in some security based presentations. I think setting up some boxes for "security" testing would be really cool. I'd be willing to donate my box to the cause. I'd also like to see a tutorial on iptables, cause they are a very usual thing. Other than that, I think a demo on wine, and getting some of that other OS's programs like dreamweaver mx, to work under wine. ================================================= | Chuck Haines | AIM: CyberGrex | | ECE Sys Admin | Yahoo: CyberGrex_27 | | GDC Developer | ICQ: 3707881 | ================================================= http://www.linux-xtreme.net -----Original Message----- From: Andy Stewart [mailto:andystewart@attbi.com] Sent: Saturday, November 30, 2002 6:56 PM To: Worcester Linux Users' Group Subject: [Wlug] Let's make WLUG meetings better! HI everybody, I was a little disappointed at the turnout from the last WLUG meeting. We had 8 or 9 people show up, and while we did have a good time watching Scott and Doug get a couple of scanners working under Linux, it would have been alot more fun with more people in attendance. I believe this was the lowest attendance we've seen at a WLUG meeting in our 5.5 year history. :-( We discussed possible reasons for the low attendance at the Boynton over a few beers. One suggestion was that I should update the WLUG website to show what we have done at past meetings so people wouldn't think that nothing was accomplished. I've done that and will endeavor to keep that part of the WLUG website current (see "Past Meeting Information"). Another thought was that some people will only come to a meeting if the topic looks interesting to them, and if it is announced well in advance. I must admit to having been somewhat lax in that area lately. Therefore, in an attempt to remedy that (at least for this month), I'm putting out the call now for a speaker and a topic for the Dec. 12th meeting (its coming up fast!). I sent out a list of potential topics last month, but I know that there are a zilliion interesting things happening in the Linux world that could be discussed at a WLUG meeting. The meeting need not be discussion based, either! Although Kinnicutt Hall lends itself well to this type of meeting, we do have access to other rooms on campus. People have tossed out ideas such as these: o build a network for multiplayer Linux games o build a network to see if WLUG crackers can break into your system (not to destroy it, but to teach you what to fix to secure your system) o more live demos! The group exists to meet your needs, so please, state your needs! I can't arrange a meeting to your liking if I get no feedback on what you want to see at future WLUG meetings. More importantly, I'd like to see more and different people volunteer to do the presentations or to run a live demo. If you look back at the last year of WLUG meetings, you'll see the same names many times. While I'm *quite* happy that these folks continue to volunteer, I'd like to see others jump in also. Finally, if anybody has feedback regarding the last meeting and why it lacked attendees, please bring it up on the list so we can all discuss it. Without such candid discussions, WLUG cannot improve.

Meeting Topic Discussion
by Andy Stewart 07 Dec '02

07 Dec '02

HI Everybody, I've seen some good ideas floating around out there, as I knew I would once the topic got going. Now the question you'll all hate: who wants to do the presentation? :-) Is there anybody out there who is pretty well versed in IPTables that would be willing to address the next WLUG meeting? Just a thought: Do we want to ask Robert Ziegler to come back and address WLUG? He authored the Linux Firewalls book published by New Riders which was updated for IPTables. He addressed WLUG about 18 months ago and his talk was extremely detailed and technical. To be fair, some thought it was a bit too detailed and dry. Along those lines, I thought it might be good to discuss the distribution specific ways that firewalling is handled. I suspect that those are just GUIs that build a list of IPTables filters anyway. Is there anybody out there that is comfortable with discussing this for RedHat at the upcoming meeting? How about some other distro? Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

fetchmail/sendmail problem... HELP
by Bill Mills-Curran 06 Dec '02

06 Dec '02

I REALLY need some help. I've included a lot of diagnostic stuff in this email to help the troubleshooting process. Please help. I'm struggling & I need some advice. The basic problem is that something changed between last night and this morning to make my email not work. Config details: ISP: charter email address subssn594(a)charter.net I use fetchmail to grab the email from the pop server (pop.charter.net) and deliver it to my local email account on my linux box (Red Hat 8.0) username on linux: bcurran fetchmailrc: poll pop.charter.net user subssn594 password xxxx fetchall When I run "fetchmail -v -v" I get good authentication, etc for both IMAP and POP3. I can see a list of email messages. When it retrieves messages I get (I'll just show the POP3 -- the IMAP is similar): fetchmail: POP3< +OK 2003 bytes will follow reading message 1 of 46 (2003 octets) About to rewrite Return-Path: <owner-gobruins(a)gobruins.ICSL.UCLA.EDU> Rewritten version is Return-Path: <owner-gobruins(a)gobruins.ICSL.UCLA.EDU> About to rewrite From: John Houser <jchouser(a)yahoo.com> Rewritten version is From: John Houser <jchouser(a)yahoo.com> About to rewrite To: gobruins(a)gobruins.icsl.ucla.edu Rewritten version is To: gobruins(a)gobruins.icsl.ucla.edu About to rewrite Sender: owner-gobruins(a)gobruins.icsl.ucla.edu Rewritten version is Sender: owner-gobruins(a)gobruins.icsl.ucla.edu fetchmail: timeout after 30 seconds waiting for listener to respond. fetchmail: client/server synchronization error while delivering to SMTP host pop.charter.net fetchmail: Query status=7 (ERROR) fetchmail: Deleting fetchids file. fetchmail: normal termination, status 7 Now, what I find is interesting is the message: Fetchmail: client/server synchronization error while delivering to SMTP host pop.charter.net It looks like it's trying to deliver to the pop server rather than my local account. WHY???? More stuff... I can email myself locally, so the SMTP server on my machine would appear to be ok. I can also telnet to the POP3 server and perform operations. My prime suspect is fetchmail. Somehow it seems to behave differently, and I have no idea why. Maybe there are different DNS entries or something causing fetchmail to deliver to the wrong place. (Of course, I don't know that the SMTP message is accurate or misleading.) TIA, Bill P.S. If you'd like to chat on the phone, please feel free. I need to get this fixed. -- Bill Mills-Curran Mills-Curran_Bill(a)emc.com EMC Corporation Tel: 508 382-7642 Coslin Drive, MS C33 Fax: 508 382-7913 Southboro, MA 01772 Tie: 824-27642

web hosting
by Baris Hasdemir 06 Dec '02

06 Dec '02

hi all, I have a domain(hasdemir.com) hosted on linux by a web hosting company. Nowadays many emails that I have sent, neither bounce back or be received by the other company. Help desk of the web hosting company told me that probably there are filters for our network (by the way I have no idea on what network means here). here is what they exactly told me: >> why would they filter my domain which has only three email accounts, >> and never spammed throughout its life? > They don't block domain by domain but they block a whole network, they > don't care many domains in that network are legit. They are quite bad on informing the customer about ant problem. they refuse to show me the SMTP logs. It is Exim as far as I know. Would any of you tell me what my problem really might be? I need my web site hosted on a linux machine with mysql and php installed. What would your recommandations be for a web hosting firm? Things I would like to have, shell account with ssh connectivity and web space around 100MB. thanks, baris

AYE AYE! :) i've been toying with getting WINE to work with Warcraft II, but although it's supposed to work, i can't seem to get it to do anything constructive. 8( as for the iptables, i know that it was done a little over a year ago, but maybe there could be a bit of an update session, to cover anything that has changed since then... for example, i was looking at a guide to using the iproute2 suite, and i think there are a lot of things that i need to learn. again. <g> -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- William Smith wsmith-at-chezsmith-dot-com Fall River, MA http://www.chezsmith.com "Never to be credited when telling the truth." -- Aristotle, when he was asked what a man gains by telling a lie. * TAG! v3.1 *

printing config question
by Bill Mills-Curran 05 Dec '02

05 Dec '02

Problem: I'm not able to print multiple copies (or access any printer options). My setup... I have print queues configured on machines at home (parallel port connect) and at work (printing to smb printers on the network). In both cases, I'm running Red Hat 8.0. I have not installed cups. I'm using the CANON bjc600 driver at home and "Postscript Printer" at work. How can I get lpr options to work? TIA, Bill

regular SCSI errors in log

I've just noticed that a server I support has been logging SCSI errors every Friday at about the same time. It's just a quick blip of error messages, then on to normal business: Nov 29 20:31:25 esd-tls01 kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 28000002 Nov 29 20:31:25 esd-tls01 kernel: Current sd08:07: sense key Hardware Error Nov 29 20:31:25 esd-tls01 kernel: Additional sense indicates Internal target failure Nov 29 20:31:25 esd-tls01 kernel: I/O error: dev 08:07, sector 92510 Nov 29 20:31:25 esd-tls01 kernel: sym53c896-0-<0,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 15) Nov 29 20:31:29 esd-tls01 kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 28000002 Nov 29 20:31:29 esd-tls01 kernel: Current sd08:07: sense key Hardware Error Nov 29 20:31:29 esd-tls01 kernel: Additional sense indicates Internal target failure Nov 29 20:31:29 esd-tls01 kernel: I/O error: dev 08:07, sector 92510 Nov 29 20:31:29 esd-tls01 kernel: sym53c896-0-<0,*>: FAST-20 WIDE SCSI 40.0 MB/s (50.0 ns, offset 15) Here's the output of "cat /proc/scsi/scsi" Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DGHS09Y CLAR09 Rev: 1A1A Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: SEAGATE Model: ST39102L CLAR09 Rev: AV05 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: ESG-SHV Model: SCA HSBP M8 Rev: 0.05 Type: Processor ANSI SCSI revision: 02 Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: DGC Model: RAID 5 Rev: 0847 Type: Direct-Access ANSI SCSI revision: 04 Host: scsi3 Channel: 00 Id: 00 Lun: 01 Vendor: DGC Model: RAID 5 Rev: 0847 Type: Direct-Access ANSI SCSI revision: 04 I've looked at my cron jobs, and I see anything that runs about that time on Fridays.

Lan party ideas...
by Keller, Tim 03 Dec '02

03 Dec '02

Hey All, So after reading Andy's email, it got me thinking about the whole installfest/lan party thing... and I'd like some input. 1. Do the members of WLUG think a lan party is a possible thing? 2. How many people do you think we could get to attend? 2a. How many people would we want to attend? At a certain point, if 200 people show up, it could get ugly... 3. Where and When could we hold such a shindig? Would this be something that the support staff at WPI would even entertain as an idea? Or, should we look else were... such as a VFW or some such place... 4. Should we have a link to the outside world, or should it just be an isolated LAN? 5. Time Frame... 6. What should we charge people (if anything) to attend? 7. Activities? This is where I want some broad input. Other than the obligatory FPS/RTS games, what other games or "stuff" would people like to see? I know Andy had mentioned a security demo... How about a clustering demo... Let me know what your ideas are... Thanks, Tim.
