Re: [SLUG] Special Interest Group: Asterisk
There is an australian asterisk usergroup. Not sure how official it is. http://groups.yahoo.com/group/asterisk-anz/ There might be enough numbers within this group to start a sydney based group that can actually meet up and have talks, if that is the goal.

[SLUG] Backup Internet links
This is quite lengthy so I hope people with a lot of time in their hands can help me out... =P I'm trying to configure Internet redundancy for a medium-sized company using Linux as their primary router/firewall. We had a 2nd ADSL line connected both from different ISP's so if one link goes down we have another one going. Please note that I am *not* setting up load balancing. The Linux router's setup is pretty straightforward. It has 3 network cards. 1 goes to ISP1, 1 to ISP2 and 1 to the LAN. * ISP1 is only used for incoming traffic (Primary MX, HTTP/HTTPS, etc.) * ISP2 is only used for outgoing traffic (primary gateway with the lowest metric on the routing table -- all traffic like web, outgoing SMTP passes through here; this is also configured as the seconday MX so if ISP1 goes down then mail flows through here) Things I am aware of/have considered: 1. If the Linux system goes down then the net is fully offline. 2. We have tried 2 Linux machines, one for each ADSL link but we have a lot of Windows machines whose metric-based routing does not work as expected when one of the links go down. Since our priorities are only internal web access and incoming/outgoing mails I have thought of periodically checking of the immediate gateways of both ISPs are online. If the primary gateway is down then run a script that changes the default route. As much as possible I would like to avoid using a routing protocol as these links are not that fast and the ISP supplied routers we have are not Cisco-enterprise-level. I do not know of such an app that checks if the immediate gateway is online then runs scripts if they are down... Any ideas?

[SLUG] Re: search engine ranking
I was asked how to improve a web site to improve its position for search engine rankings. I had to reply "I don't have a clue". There is a lot of "noise" looking for info on the subject. Any body recommend some urls to read, so I can pass them on please? Search engines alsorelies on the META data in HTML pages, specifically META Description and Keyword. Mind you that it does not affect page *rankings* but affects the kind of searches your pages should appear in. So if you put "microsoft" as your keyword, your page will definitely come up in a microsoft search on Google but whether it's on rank 1 or 1,000,000,000 is where that black art comes into play.

[SLUG] hard links over the net
Hi all, I have a backup server in my LAN that keeps some rsnapshot (www.rsnapshot.org) backups. For those of you who don't know the tool, rsnapshot works by taking incremental backups, hard linking the files that don't change from one backup to the next (thus, keeping the consecutive backups smaller than the first big one.) I want to send these backups to a remote server every day or so. I tried scp'ing it, but scp resolves the hard links, causing me headaches and too much space to be used in my remote server. I then tried SSHFS (sshfs.sourceforge.net), and the same thing happened. Same applies to SHFS. I know NFS would keep the hard links instead of resolving them (cp -d), but I'm not up to put NFS over the internet since that can be a bad idea from the security standpoint. So my question is: is there a way for me to make that transfer and keep the hard links? Thanks. -- Julio C.

The 100MB video file is local (ie on the hard drive of the machine running the browser. In fact I've tried putting a smaller 20MB video, the mplayer app, it's libraries, the plugin manager and it's libraries and the html all in a ramdisk. The sort of response I'm getting is after clicking the link to the video it's taking about 1 to 2 seconds to kick in. I am not sure if it's the browser itself or the plugin manager causing the delay, but if I replace mplaer with a shell script that logs the command line parameters the delay is between clicking the URL and the log entry appearing. Running mplayer directly gives excellent response, ie before the enter key lifts up. I've tried a few browsers and tried to try a few plugin managers with varying success (ie got it to run or didn't). It looks like the common theme is it seems to want to buffer the video when it probably shouldn't. Of course the long term plan would probably be to have somebody code up something that'll call mplayer or flashplayer or render a web page on cue. I've heard gstreamer might be able to do something like this but so far I thought it was used to process video, not display it.

This doesn't answer your question, but you can setup rsync (from memory with --backup and --backup-dir) so that you have one full copy of the latest backup, and in separate directories just the files that changed each backup run. Alternatively, just run rsync, then on the remote host, run rsnapshot. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Then make it executeable, cron it, or put it in a while loop if you need more
than 1 minute granularity.
Flaws (among others):
1. Handling previous states (last run status) is rather rudimentary and could
be done better.
2. Possible race conditions - not sure...looks ok, but I might have messed up
the logic somewhere shrug Be careful running this script too often. If
you run it with the routing tables in a state of flux/transition, this
script will break and do horrible things to your system's nether

be bothered messing with syntax this
