Re: [SLUG] Need a lesson in routing [WAS: memory]
Perhaps you can use a socks proxy through a SSH tunnel and ask the Linux box to do DNS for you. This means the only thing that is affecting your speed behind the firewall is the actual connection between the host(running FF) and the firewall. e.g. on the Mac/Windows, ssh -D 1234 u...@linux_box and configure FF to use 'localhost' as the SOCKS proxy, port is 1234. Change 'network.proxy.socks_remote_dns' in FF to true. I wonder if this would result in any significant speed boost. Likewise, make a tunnel to your IMAP server, e.g. ssh -L 993:localhost: 993 u...@linux_box and configure TB to use 'localhost' as the IMAP server. If neither is speeding things up, it seems that might you have a slow connection between your Linux and the host you are running FF. Chris On 21/02/2009, at 4:41 PM, Kyle wrote: ... OK!!! That is indeed what it does Michael, when it doesn't timeout. I had previously read up on F'Fox and turned on the various turbocharging options, but hadn't thought of ipv6. So I changed network.dns.disableIPv6 to true on the hosts behind the switch and Wow! That's a bit more like what I might expect. ipv6 has always been a bit of a black box I've tried to avoid as long as possible. Guess I need to start reading up on it. Or disabling it! Allow me here to thank each and every one of you that have put up with my ignorance to assist in debugging this issue. I'm not convinced that's all there is to it just yet. For instance, the Linux box is still an order of magnitude faster to load a page, network.dns.disableIPv6 is true by default in T'Bird on the hosts which still timeout on initial connection and all hosts are only using the linux box itself as name server. But where we are now will go a long way to dispersing aggravation in the local browsing community.

I'm wondering if firefox is doing IPv6 lookups and failing. If you want to test, disable IPv6 in firefox (about:config) or use the same nameservers as the linux router -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Re: Mythbuntu box shutting down at random
Wished I could Simon, but the machine won't even boot past the BIOS post now... I'm considering replacing the mobo and just having done with it. You know some times you don't mind spending several days trying to work everything out and some times you're only willing to spend a day??? This is one of those times :)) Thanks for the advice though. I'm curious about the option of the box sending an e-mail...I've heard about this before but not read anything about how to do it.

This is slower than dialup speeds. (A little b is always bits *not* bytes, which is B in communication speek). Even if you meant 15 000 bytes per second (which equate to 150 000 is slow). So I am not sure what you really mean here. I discussed this with Kyle off-list, and we realised that he's missing some zeros - his dsl modem actually reports 15,000Kbps The rest of Martin's points stand :) -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Re: Mythbuntu box shutting down at random
Hi Patrick, pull out everything that is not needed to start the box up. you only need a video card. check that your IDE cables are the right way. only connect one IDE device like the HDD. pull out network cards and anything else in there. pull out all memory except one chip. also try changing the keyboard to another (i once had a faulty KB that caused the HDD to report failure - go figure!) reset the BIOS to factory defaults. if it boots then add one device back at a time. reseating everything in there also. make sure you keep yourself grounded eg. by leaving the power supply plugged in and off and having one hand touching the case all the time.

Re: [SLUG] Mythbuntu box shutting down at random
Hi Elliot, I may be way off here, but I had the same problem a while ago. It turned out that the power supply had a fault which started as random and then eventually the machine would not boot; whenever something caused a spike like when a HDD firing up it couldn't cope. It was hard to diagnose. I fixed the problem by getting a better quality power supply. Heracles elliott-brennan wrote: Hi all, I have Mythbuntu running on a 3Ghz P4 1.5G RAM, 500G HDD, two PVR-150 video cards and a 128mb nVidia card. On the odd occasion the machine decides to reboot, for no particular reason. Tonight, for instance, my wife was watching the ABC and the machine just borked and rebooted. She wasn't 'doing' anything and the machine was doing nothing but showing the TV...no additional work. It's done this irregularly (eg. not every day and not at the same time) and I can't work out a pattern. Last week I had serious problems getting it to stay alive for more than 10 minutes. I finally replaced the BIOS battery and it was fine. Can anyone suggest something I should look at? Thanks in advance.
