[Slightly OT] Port forwarding (Was: How to restart the root serverfrom within modperl?)

2003-08-14 Thread Andrew Ho
Hello,

MLIf you absolutely need to be in port 80, either setup a simple 
MLlightweight apache on port 80 as a reverse proxy (see the mod_perl 
MLguide) or, even simpler, do some port forwarding from port 80 to your 
MLhigh port of choice.

Has anybody had very good experiences using a simple port forwarder in a
production setup? We had a somewhat bad experience with using portfwd
under Solaris (images and other binary data got randomly corrupted, and we
never got around to figuring out why), and I'm wondering what others use
instead. It seems like the port forwarder involved would also be important
performance wise.

The applications I am typically interested in are forwarding ports on the
same interface (like the port 80 example here) as well as between
interfaces (or between external interfaces and loopback).

Humbly,

Andrew

Hi, 
I once saw an example of port forwarding using netcat and inetd, i think it involved 
setting up a listening netcat as the application, using inetd to bind it to a specific 
port and then forwarding the connection onwards to the ip and/or port where you want 
it to go, something like this:

service geofwd  
{  
   flags = REUSE  
   socket_type = stream  
   wait = no  
   user = root  
   server = /usr/bin/nc  
   server_args = 192.168.124.38 1005  
   log_on_failure += USERID  
} 


not sure if this is what you want :-)
