OK, first of all, eskimo.iglu.org.il and beak.hamakor.org.il are two
completely different servers. They reside in the same place (Actcom), but are
administered by different teams, and serve different purposes. iglu.org.il is
the older of the two, it's a Pentium III machine (500 MHz or more - can't
remember), and we use it to host www.iglu.org.il, www.hackers.org.il,
jlc.iglu.org.il, and other domains. It is also a Web/FTP server for various
mirrors. It was originally donated by HP and Ligad. beak.hamakor.org.il is a
newer P4 machine with a bigger RAID array. (200GB+, IIRC). AFAIR it was
donated by IBM.
As for statistics:
[EMAIL PROTECTED]:~$ df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda6 5619520 1898384 3721136 34% /

/dev/md0 70004400 38491712 31512688 55% /storage
We also have other partitions, but they took part in the older configuration
and may still contain important data. Having a bigger /sd{a,b} will allow us
to simply copy all of them to a nice directory there for propsperity. we can
also do it in /storage. Our /etc/fstab reads:

Nadav, if you'd like an account on iglu.org.il, I can gladly set one up for
you and give you the root password. I can send you a message encrypted with
your key with all the information.

Right.

beak has too many mirrors anyhow. In any case, the philosophies behind the
management of beak and eskimo are different. In eskimo, we give accounts
relatively liberally, we install all the software we need, (even if it had a
relatively poor security record) and we don't do chroot games. It is also
(IMHO at least) more of a community server than beak.
So, what I'm saying is that we need to make sure eskimo is also a capable
server.

Well, I'm not sure eskimo even have an IDE connectors. And generally, the
Linux kernel is rumoured to misbehave (or at least used to misbehave) in
mixed IDE/SCSI environments. But if you'd like to buy an entirely new
IDE-based server (with very large IDE disks - we need more than 160 GB) I'll
be pretty happy to ditch the current machine hosting eskimo, and switch to
it.
Note that SCSI is known to be more reliable than IDE, but I'm not an hardware
expert. Just contact iglu-web regarding the prices so we can debate on the
proper space/cost compromise.

Right. Nevertheless, I'm a bit tired of keeping this between the circles of
the IGLU-web mailing list and would like to put it in the open. (without
accusing anyone, of course - just requesting donations).

It has no physical space left. And like I said, I don't think it even has IDE
connectors.

I think it would be easier to buy a new IDE-based machine, than to try to
convert the current eskimo machine into an IDE configuration. Either we buy
new UW-SCSI disks for eskimo or we get a new machine (IDE or whatever).
Trying to IDEize eskimo is A Bad Idea<tm>.

Right. +1.
