Topic: SME 8 & CLIB 2.7

[InteXX]

Hello

According to the main SME 8 page (http://wiki.contribs.org/SME_Server_8), we're running on CentOS 5.8. I think I need 6.0+ for what I'm trying to do, but hopefully not.

Is there a way to install CLIB 2.7+, as noted here? (http://community.logmein.com/t5/Hamachi/HELP-Hamachi-in-CentOS-4-i386/td-p/77417#M5746)

I can't tell you enough how much I need to run Hamachi on SME 8. It's absolutely critical.

Thanks,
Jeff Bowman

you could start getting more info on CLIB on Centos6, i.e. rpm name etc.

digging with google returns nothing.. I think it could refer to glibc 2.7.. in that case, you can't do anything..

[InteXX]

Rats, I think I'm stuck with Ubuntu.

try to explain why..

[InteXX]

But of course 

Biggest need:
I have to join an offsite workstation to the domain.

Next biggest need:
Non-domain offsite machines need access to network resources (ex: RDP), without having open firewall ports.

Smallest need: (but still important)
Outside access to network points via hostname, where the public IP is dynamic.

the answer is man ssh, switch -r  -R, and google

I must say, you lost me at the bakery with that one...

I think I see...

So you're suggesting using SSH instead of VPN, I believe?

Wouldn't that require static IP and open firewall ports, though?

[Stefano]

ok.. you look confused

let's say you have a remote server (let's call it A) you want to connect to, but you can't open firewall ports on the remote side, so you can't just ssh o vpn to the remote server.

with reverse tunneling, you have a outgoing ssh connection from the remote server (i.e. no need for open firewall ports if there's no outgoing filtering rules on the remote side) to your server  or a server you can ssh to (let's call it B)

when you want to connect to A, simply ssh to B and then ssh to localhost:portofyourchoice... you will be redirected to A

no need of fixed ip on A side.. neither on B side if you use something like dyndns
obviously you need something to keep outgoing ssh connection up all the time; I'm quite sure you'll find some script example out there to do it

Gotcha. I'll have a look.

That was quick.

I've decided against it, no offense please. Client setup and maintenance sounds too complex for several machines.

The beauty of Hamachi lies largely in its simplicity. Set it and forget it.

I'll still be able to use SME, though. I'll run Ubuntu Server in a VM under a DHCP reservation on a Windows workstation and set the VM as the Hamachi gateway.

I've done this before with reliable success. It's clunky, but it works. I was only hoping to get away from it and install Hamachi on the DC.

To your knowledge, will we be on CentOS 5.8 until SME 9?

SME Server 8.x will be based on the CentOS 5.x base, so most likely, yes.

[InteXX]

most likely, yes.

OK, thanks.
