MTS SMTP
by Trevor Cordes 18 Dec '05

18 Dec '05

Someone (I think Shawn) was asking about this last meeting. I just hit this problem (or one related) also. Looks like MTS mail servers are not accepting email from RBL'd (ie: all Shaw dynamic IP's) servers anymore. If you run your own mail server on Shaw and you don't smarthost all email, you'll have to add a rule just for MTS to your /etc/mail/mailertable like: mts.net esmtp:shawmail.wp.shawcable.net and more for any mts-related domains (that all use the same MX) like escape.ca. Note, this won't apply to most people with simple email setups: this only applies to us weird people trying to run mail servers off of dynamic IP's. And, yes, leave it to MTS to do this in a non-standard way: they are just dropping the connection giving 554 service unavailable when they should be giving us a bounce with an indication we're being RBL'd so we know what the heck is going on.

Accurate Monitoring of system load
by John Lange 16 Dec '05

16 Dec '05

Does anyone have any suggestions for accurate monitoring of system load on web servers? In the situation where you have a server which is hosting multiple applications I've found it next to impossible to determine with any accuracy what applications or pages within those applications are causing load. At any given moment its easy to see what is using CPU and memory. But in the case of a web server these are brief spikes that don't mean anything. Whats needed is a way to see what has caused the most load over a given time period (say the last 10 minutes). Does anyone have any suggestions for tools that can help determine load. -- John Lange OpenIT ltd. www.Open-IT.ca (204) 885 0872 VoIP, Web services, Linux Consulting, Server Co-Location

Re: [RndTbl] Samba server
by Dan Martin 03 Dec '05

03 Dec '05

Sugumar: I assume you got my address from the MUUG roundtable posting, so I will post my reply there. I am new at setting up Samba, so others may have more accurate or helpful information for you. I basically followed the example in http://www.quickfixnotebook.com/ which is well worth buying from Copperfields if you have a number of setup issues to deal with using Fedora Core. I think most of the examples in the first edition are for FC1, but the author is aware of FC2 and FC3. Using FC4, I had trouble with SE Linux enabled. Only after extensive Googling did I find that SE Linux was the cause of my woes in setting up Samba. Contrary to the web info I found, re-enabling SE Linux afterward did NOT allow proper directory sharing, and I continue to boot without SE Linux enabled. The Samba Howto http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/ is helpful, and there are examples of smb.conf files in the fast start section including one for a domain controller http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/FastStart.html#i… To answer your questions: 1) to make your Samba server a PDC, you need to set its priority higher than that of your competing Windows machines. The smb.conf setting os level = 65 is generally sufficient. I am also using domain master = yes security = domain but I think security = domain is not necessary to make Samba your PDC. Take that info with a grain of salt. 2) I am using passdb backend = tdbsam No configuration of the database was required. Everything was just there. I am not using LDAP - it looks like there is considerable setup, and it is probably not necessary unless you plan on scaling up to a large network with subnets on it. If you are using a similar system and this is even remotely helpful, I would be glad to post or send my smb.conf file. sugumar c wrote: >hello > > How to configer samba PDC server and how to use >LDAP server > >pls explan. i am waiting for your replay > >bye >sugumar.c > >--- Dan Martin <ummar143(a)cc.umanitoba.ca> wrote: > > > >>The problem is SE Linux. >> >>I finally found the solution to this problem on >>Google by adding more >>search terms >> >> >> >http://readlist.com/lists/redhat.com/fedora-list/14/73268.html > > >>> >>This two services was working OK before >>> >>my >>> >>update from FC3 >>> >> >>> >>I think that it was having something to do with >>> >>> >>SE, because to >> >> >>> >>solution >>> >>this I had to turn off SE, reboot, then turn on >>> >>> >>SE & reboot again, >> >> >>> >>this >>> >>(I think) relabeled the entire file system & >>> >>> >>after this; no more >> >> >>> >>problems with the smb & ppp0 services getting >>> >>> >>working ok. >> >> >>> >> >>> >>> >>I booted after turning off SE, and it works - after >>many frustrating >>hours of looking for the problem in Samba. >> >>Dan Martin wrote: >> >> >> >>>I have been playing with Samba 3 on FC4 for over 3 >>> >>> >>days now, and it's >> >> >>>starting to get not fun. >>> >>>Samba appears to be up and running and the network >>> >>> >>is functional. >> >> >>>When I browse the network on my Windows machines >>> >>> >>(one is Win 2000 pro >> >> >>>the other is NT4) I am prompted for a >>> >>> >>username/password, then the >> >> >>>server shows on the network.

MUUG Lines December 2005 Errata
by gedetil＠cs.umanitoba.ca 30 Nov '05

30 Nov '05

Hi folks. The December issue of MUUG Lines, our monthly newsletter, was mailed out this morning. We rushed to get it out earlier than usual, to hopefully beat the holiday rush, and get the newsletters to you in time for the meeting. Unfortunately, we missed a couple errors, which we only noticed after it was too late: The next meeting will be on Tuesday, December 13th, 2005. The following meeting will be on Tuesday, January 10th, 2006. We've corrected these dates in the online version of the newsletter, which you can find here (in PDF, PS, and Word DOC formats)... http://www.muug.mb.ca/muuglines.html Note that we also always post the meeting schedule and abstracts online too, and you can find those here... http://www.muug.mb.ca/meetings/ As always, too, the meeting announcement will be posted to the usual mailing lists a week before the next meeting date. -- Gilbert E.

Shaw throttling torrents?
by Sean Walberg 24 Nov '05

24 Nov '05

Anyone tried downloading any distributions (or other things) using BitTorrent through Shaw? Apparently they're using Ellacoya shapers to throttle back the bandwidth. A coworker just got off the phone with their support who confirmed it. Sean -- Sean Walberg <sean(a)ertw.com> http://ertw.com
