Are you actually using this thing as an ADSL modem or just as a router? If you're not using the ADSL functionality perhaps it's time to invest in a cheap switch.

oh right ...i thought thats what was applied!!! no it doesnt have anywhere to plug the adsl cable in... just four ethernet ports On 16/05/2008, Stephen O'Neill [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Javad Ayaz wrote: | i dont get what you mean by using the ADSL functionality?

[ubuntu-uk] How to back up Dovecot IMAP?
I currently have all my email stored on a Dovecot IMAP server on my Ubuntu Dapper 6.06 server. I intend to upgrade this to Hardy using a total wipe, reformat and clean install (I have lots of crud on Dapper, such as Beryl, Automatix etc). First I would like to back up everything on the IMAP server. How do I do this please? Then, how do I restore this to a clean install of Dovecot? Ideally I'd like to write a nice cron-able script that creates a .tar.gz file, but anything that works will do. For the longer term, how can I perform incremental Dovecot IMAP backups (say, only the last 7 days worth of mail)? If it makes a difference, I am the only IMAP user on the server. Couldn't find anything immediately relevant with Google, but links to RTFM-esque articles would much appreciated.

[ubuntu-uk] Desktop wallpaper, icons and bluetooth broken in Hardy
Well, wallpaper and icons *were* working, until yesterday's package updates. I get a message about HAL failing to start on login now also. I 'm running compiz-fusion on dual head with NVidia 7000 series card with 512Mb. Both screens are at 1280x1024. Apart from the above, cube etc. works OK. Only google results I can find relate to a similar scenario using different resolutions on dual screens. Since upgrading from Gutsy to Hardy, now unable to send files over bluetooth TO the PC from a phone. Can do in opposite direction. Any ideas welcome. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.org/UKTeam/

There are so many issues with 8.04 it is untrue and for an LTS release that would suggest well tested and stable, it is nothing more than a bad joke I'm afraid; and I have placed an embargo on the release until it is stable and hopefully a cd respin i.e. 8.04.1 is done that I can use without hassle and I can recommend to others.

Re: [ubuntu-uk] UDS Questions for the podcast
Popey, thanks for the opportunity to contribute. My question is this: With Hardy being very solid now, and the kernel being very good in terms of hardware support, isn't it time that there was a focus on Ubuntu's look and feel, both in terms of theme and usability issues. Being mindful of the fact that the forthcoming artwork refresh seems to have been shelved indefinitely (clarification on this issue would be welcome) a visual makeover is definitely long overdue IMHO...

Re: [ubuntu-uk] {Spam?} Re: transferring files between Ubuntu and XP slow!!!!
It's not simply eight bits per byte for ethernet packets, it's more complicated than that and you're not taking into account collisions. Im a bit confused now... so how... I mean a Byte is 8 bits, a bit being either 1 or 0... I thought that was a fundemental of computer science.

I mean a Byte is 8 bits, a bit being either 1 or 0... I thought that was a fundemental of computer science. Am I wrong? In a typical technical response, yes and not. There are 8 bits in a byte (well an 8 bit byte anyway), an ethernet packet usually* holds 1500 bytes. However, the packet has to know where it's going, so that uses some extra data, and where it's come from, and have a checksum, to it can tell if it's been corrupted in transit. Then there is the problem that networks aren't perfect and problems (collisions) do occur, and packets need to retransmitted, a packet retransmitted is a packet lost... So while a 100 MEGA Bit/Second link can in theory send 12.5 Mega bytes/Sec, in practice you lose up to 30% of the throughput in overheads. So you're looking at around 9 MegaBytes/sec. With poor wiring and non-switching hubs you can lose even more... Wireless network lose even more of the headline rate, as the bandwidth shared among the clients... It gets very complicated very quickly, but if you are interested, have a google for the ISO 7 Layer model... :) -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.org/UKTeam/
