Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Scenario:

Central Log-Server(say logserv)- only private IP interfaces

Multiple client servers (logclient)- has public IPs.

Requirement:

Need to tcp logs of syslog application from logclient to logserv.

Is this possible to achieve this using "stunnel", like its normally implemented via reverse tunnelling with ssh and autossh? Is reverse tunnelling possible with "stunnel".

Kindly advise.

I don't think you are going to be able to get stunnel to work in this setup.' –  Zoredache Oct 3 '12 at 19:23
    
Thanks. So guess I'll have to rely on reverse ssh or autossh, right? In this regard is there a client-server application which runs as a service and supports reverse tunneling? –  user492160 Oct 4 '12 at 2:20

Almost any VPN would work. I like OpenVPN, it is very flexible, though the initial learning curve might be difficult. –  Zoredache Oct 4 '12 at 2:27
    
Thanks. Please correct if I'm wrong- I'll have to create an openvpn network with logserv and mulitple logclients as a part of it. After this I'll be able to tcp logs from clients to logserv via private IP interfaces, so I'll be able to avoid using public IPs totally. (The logserv is already part of another vpn network). –  user492160 Oct 4 '12 at 2:35
    
Yes, that should be correct. –  Zoredache Oct 4 '12 at 2:50
