Hello everyone!

I'm posting here to ask several questions bout Amazon EC2 and Linux on it. I'm from Russia and further events, like elections in March, can be quite dangerous to  average Internet user in the way of blocking sites. Like in China or Kazahstan. 

That's why, I'd like to have my own proxy server in the external cloud. Which problems I can face messing up with it? Is the solution for 27$/month okay for such configuration? 

More than that: I'd like to have my jabber-server with ICQ<->Jabber and GTalk<->Jabber transport. Where are pitfalls here? Can you give me any mans/instructions/guides?

Thank you.

Vlad

I have  something like that (in the UK) - a linux virtual server with a 
little RAM and a little disk - and enormous shared CPU and bandwidth.

So far it has been (for the money) more than I dared hope for. RAM is 
getting tight at 384 Mbytes - sometimes it goes a tad swappy..

I'll pass on that, beyond the obvious point that the SECOND thing you do 
after you have a basic remote install up and running, is to firewall 
EVERTYHING except yourself and your own SSH or whatever, out.

START with absolute security - and look at something like Rsync to not 
only back the machine up elsewhere, but also send you a message of WHAT 
HAS CHANGED. In case something you didn't change yourself has been 
changed by someone else.


Do NOT leave an unfirewalled machine on the internet anymore than you 
would leave a wallet full of money on a train.. I had probing attacks 
within hours.

Make security the absolute bedrock of everything you do. Assume that if 
some script exists to hack or DOS a server, someone somewhere will find 
it and use it on YOU.

Otherwise if you get blacklisted, it's a waste of all that effort?

I got it. So: install OS, then close all possible backdoors and start configuring. Such way?
 
But I have another question: I'd like to have any guides to install my own jabber server WITH (most important) name resolve (ka2m instead of 59394923@somedomain). Where can I find'em?

Yes.

Where can I find'em?

I dont even know what jabber is.

You can do anything you like LOCALLY as far as name resolution goes by 
using the /etc/hosts table or running (and using) your pwn DNS server 
(bind9)and faking domains on it.

Maybe you know what XMPP is?

Have you looked at jabber.org? Last time I was there, it had some HOWTOs
and listed a bunch of server software. The one written in Erlang was
good when I tried it several years ago.

Regarding name resolving, doesn't this happen as part of XMPP
anyway? I've only ever seen issues of silly names with entities such as
chat.facebook.com, and those tend to disappear once the client (pidgin,
in my case) has had a message from the remote.

Sorry not to be more useful, but it's been a long while since I ran my
own server.

Thanks.

I'd look for it at jabber.org:)
