Portfwd - Port forwarding daemon
portfwd [-d ...] [-g] [-t] [ -c
This manual page documents briefly the
Portfwd stands for port forwarding daemon. Its a small userland tool which
forwards incoming TCP connections and/or UDP datagrams to remote
hosts. There is support for FTP forwarding, transparent proxy, DNS on
demand, simple round-robin load-balacing, external destination
selectors and other minor features.
This authors English skills are very bad as hes not a native speaker
of that language -- please feel free to contribute fixes for this page
if you can.
The program follows the usual GNU command line syntax, with long
options starting with two dashes (-).
A summary of options is included below.
-h, --help ||
Shows summary of options.
-v, --version |
Shows program version.
-d, --debug |
This option increases logging verbosity for debug. Up to 3 switches
are meaningful. Failure messages are sent to the system log under
-g, --foreground |
Specify this option to keep the daemon running in foregroud.
-t, --transparent-proxy |
This switch enables transparent proxying. If you intend to forward
data to hosts behind your masquerading firewall, you probably want
this option turned on; it allows your servers to see true IP addresses
-f, --on-the-fly-dns |
Portfwd usually solves all DNS hostnames upon startup. Specify the -f
option if you want the destination hostnames be updated on demand. Be
aware this can affect TCP connection times and the whole UDP
-c, --config config-file |
This argument allows specification of a configuration file other than
the hard-coded default.
config-file is the full pathname to the configuration file.
Default configuration file. This may be changed by the "configure" script in compile time.
If sent to Portfwd master process (the one with lowest PID), the TERM
signal terminates the whole forwarding job.
