Re: out of port numbers

Suppose an application needs a port to setup a connection but all port
numbers are already taken by other established and time-waited
connections.

Yes these are default Linux settings (cat
/proc/sys/net/ipv4/ip_local_port_range).

I am seeings a lot of port-reuses in the tcpdumps. The tcpdump was
captured on a Debian master that runs multiple Debian guests (Linux
VServer). Among others, it runs a proxy and application server that
setup a new connection for each HTTP request that is being served.

Cheers,
