As far as I know standard connection for South Korea home users is 100 Mb/s. *sigh* Not in the UK. Standard DSL upload speed for the majority is 448Kb/sec - 830Kb/sec on a business line, or up to 1.2Mb/sec on ADSL2+. The lucky ones on FTTC get 2Mb/sec, or up to 10Mb/sec if they pay silly amounts more. (I have one FTTC customer - they get 30Mb/sec in and 9.5Mb/sec out - they're 2 weeks into their first months usage and have already consumed nearly half their 90GB allowance )-: So there's still a lot of value in using USB data keys/CD/DVD to transport large quantities of data! However, personally I'd much rather have higher data caps and lower contention and more stabiltiy than high speed any day of the week. And it's all very well having 100Mb/sec but if there's nothing to use it with, or your international links are so congested it's not worthwhile, then ... Besides this all German universities and most big companies have 1 Gb/s and above (eg my university has 40 Gb/s). That's true for the UK Universities too (although 10 and 100Mb/sec is more common for medium sized companies - and even then it's not cheap - I have one customer on a 10Mb leased line - 1:1 contention from their premises to the edge of the ISPs network, no data cap and it's £500 a month. (They used to post DVDs to their hosting company to upload very high resolution photos to their website) The sad truth is that people here aren't willing to pay the real price - so the huge ISPs dominate - under cut everyone else, offer high speeds (relatively speaking), but then have oversubscribed networks and lowish data caps )-: So, it is good to know to have software which supports such fast links. Indeed... So one day ... And now back to LXC :) Cheers, Gordon-- Simplify data backup and recovery for your virtual environment with vRanger.

Re: [Lxc-users] trying to bridge wireless
Ok, i added the change to lxcbr0-up file and saved. I went back and used
brctl to add in the info you gave before but when i run ifup lxcbr0 i get:
dnsmasq:bad command line options: try --help
Seems as if there is some wrong network info i may have entered somewhere on
my end. Just wanted to ask if this looked like a familiar error to ya?

That can implement many of the OpenVZ compatibility things we need the high level scripts to perform and keep them in one file. Many thanks. I as SO glad to see this! I see that this has not, apparently, made it into a release bundle yet. Any idea when it will be out? It will be for the lxc-0.7.5 version. No ETA for the moment. I would like to have new feature for lxc before releasing a new version, the delta with 0.7.4 are mostly bug fixes. Just a random observation, but there would appear to be at least a couple on the list who consider this to _be_ a new feature.
