Yea, it crashes just by restarting a CT way too many times in a row

I have no trouble with yum and rpm on a 64mb VPS.
@KuJoe: I can get CentOS 6 down to 4mb on OpenVZ.

no, 2.6.18-308.el5.028stab099.3
OMFG
But no cron and syslog >_>
Do you think you might shave some more memory by using pdksh or dash instead of bash?
Replaced bash with dash and added crond and syslog-ng, sitting at 6mb.

Almost unusable if you are used to autocomplete weird filenames

still 6mb with mksh

I admit I've never benchmarked the memory usage of the shells, but I know that's what Hostigation uses for its 64/96 backup VPSes. Autocompletion works just fine with pdksh.
yeah i use pdksh quite a bit. nice shell
IPs are relatively ok-ish, but I don't foresee too many people getting 32mb plans.
From one of @Prometeus VPS:
Maybe he can share his secrets for getting the very latest .32 OVZ kernels running stably? I'm guessing his nodes aren't fully loaded yet...
Thing is, Fran, that the coming Ubuntu 12.04 LTS will require 2.6.24 or newer, because of minimum GLIBC requirements --- it won't work on 2.6.18, but works great on .32. I don't know what percentage of your clients use Ubuntu, but I imagine a lot of them will want to migrate to 12.04, especially those running 10.04 LTS....
There isn't any 'magic', it just means his users aren't as brutal as they could be
There's plenty of bug reports about it randomly dying. We got some boxes still running .32 simply because they haven't crashed.... yet.
Francisco
Exactly :S
Didn't knew that shell :P If it can do autocompletion for files and commands in the path I am happy.
LOL!
Well, tbh the mine is almost doing nothing...
will be the climate and Italian food
I wonder if at(1) takes less memory than cron. It would not be a drop-in replacement - you'd have to write the job so it reschedules itself every time
If anyone would like to purchase a LEB just throw me an email at [email protected] and I may be able to hook you up with one.
@rethinkvps: specs?

Throw me an email and I will see what I can do for you.
That was me ^^, 3MB while not logged into SSH haha
care to share how its done?
It was a while ago now, but iirc, I started with BuyVM Debian Minimal, then doing:
1. apt-get purge rsyslog && apt-get install inetutils-syslogd
2. Replace SSH with Dropbear - apt-get purge ssh openssh-server openssh-client openssh-blacklist openssh-blacklist-extra && apt-get install dropbear
3. BASH with DASH - apt-get install dash && chsh
/bin/dash
rm -f /bin/sh
ln -s /bin/dash /bin/sh
Edit: You lose a lot of useful functionality by switching to DASH, so it's not recommended unless having the extra RAM is critical. You also lose sFTP by switching to dropbear, although there's a couple scripts that allow you to switch to dropbear without losing it, but that's outside of this scope.
i have a similar script to setup a debian 6, but always getting 6mb after ssh-ing to the vps. will check again.
