Offline Repositories

[shoaibi]

I want to create a local mirror of repositories for students at my campus. I want to copy each and everything.

So tell me what i would need to change in:
http://www.arsgeek.com/?p=997

And what specs would i required? is 160GB HD enough? or should i double it?

I don't think you would have to change anything as far as commands go; just don't open it up to the outside world when you're configuring apache.

I have no idea how big the standard repos are, but I have a feeling they're pretty huge.

how much?
what if i mirror this:

okay, i am using following to mirror:

deb ftp://ftp.free.fr/mirrors/ftp.ubuntu.com/ubuntu/ hardy main restricted universe multiverse
deb ftp://ftp.free.fr/mirrors/ftp.ubuntu.com/ubuntu/ hardy-updates main restricted universe multiverse
deb ftp://ftp.free.fr/mirrors/ftp.ubuntu.com/ubuntu/ hardy-backports main restricted universe multiverse

deb-src http://archive.canonical.com/ubuntu hardy partner
deb http://apt.wicd.net hardy extras

clean ftp://ftp.free.fr/mirrors/ftp.ubuntu.com/ubuntu/

with the above mirror.lst, i want to update the repositories of my private mirror once a week, how do i do it? cron? or what?
and what if i create a LVM of 2x160=320GB HD, enough for a while?

Hardware Requirements

We require that you run a modern unix system and recommend running Ubuntu on your mirror host. It is suggested that you provide HTTP access with apache and ftp access with something like vsftp.

Providing rsync access to Ubuntu mirror directories on your mirror is also helpful.

The mirror needs to be located in a secure location reliably connected to the internet. ADSL and cable hosted mirrors will not be considered for becoming an official mirror (however are suitable for a private mirror).
Bandwidth requirements

Predicting the bandwidth requirement for becoming a Ubuntu mirror can be difficult. There are number of indicators of bandwidth usage which can be used for a guide.

Ubuntu users are encouraged to download from Ubuntu mirrors within their own country, so countries with a large population of Ubuntu users have a high bandwidth requirement for hosting a Ubuntu mirror. Conversely, Ubuntu mirrors located in countries with a small Ubuntu user population such as Indonesia will have a very low bandwidth requirement for hosting a Ubuntu mirror.

A popular Ubuntu mirror located in the United States, which has a high population of Ubuntu users, can expect to use up to 400-500 megabits of bandwidth or more. If your mirror will target a large group it may be important to apply bandwidth restrictions or Quality of Service rules to avoid impacting other systems or services on the network the Ubuntu mirror is hosted on. An Ubuntu mirror located in Indonesia, a country with a smaller Ubuntu population, may see no more than 10 megabits of bandwidth in a peek period.

Because Ubuntu users are encouraged to download from mirrors within their own country, it is important to consider national bandwidth instead of international bandwidth.

If you are unsure of the bandwidth requirements of hosting an Ubuntu mirror within your country, contact the Ubuntu mirror team for assistance.
Disk Space Requirements

To mirror the Ubuntu archive, you will need 220 gigabytes with room to grow. To mirror the Ubuntu releases you will need about 30 gigabytes. Release disk space is generally constant while archive disk space will continue to grow.

i read that.....
but mine would be private, so even if i dont follow requirements, its okay....
about that 220GB, i just wanted to ask, if it would have any problem incase of LVM?

[shifty_powers]

going by

http://en.wikipedia.org/wiki/Logical...Manager_(Linux)

ubuntu is quite happy with an lvm setup...

[hyper_ch]

it's 220 GB now for all releases... one relase is only about 40 gb... I don't think you want all the old releases also, do you?

[shoaibi]

nope, i just want to mirror hardy for the time being....
Also what about my second question? about synchronzing my local private mirror with the universal mirror once a week, how can i do it? cron? how?
