Looking at the code in TUnixSystem.cxx, the problem is quite obvious.
For example:
int TUnixSystem::UnixTcpService(int port, Bool_t reuse, int backlog,
int tcpwindowsize) {
...
if ((sp = getservbyport(port, kProtocolName)))
sport = sp->s_port;
else
sport = htons(port);
...
}
Only if no service is returned, the port is converted into network byte
order, but getservbyport() itself already want to have the port argument
in network byte order (see manpage)! That has to be changed at some
other places as well.
Best regards,
Volker
