|UREDIR(1)||General Commands Manual||UREDIR(1)|
urediris a small tool to redirect UDP traffic. It can be used as a poor man's filtering tool, e.g. for small multihomed embedded systems without a built-in firewall.
uredirforwards packets to a specified destination remembering the sender's address, any packets received from the destination are in turn forwarded to the sender. When
urediris launched from inetd(8) it does not immediately exit when the first reply has been forwarded. Instead it lingers for three (3) seconds in case more requests are received, e.g. in the case of an SNMP walk. This helps conserve precious system resources, useful in particular on embedded systems. For a TCP port redirector, try redir(1), which now has the same maintainer as uredir(1).
-n, always runs in foreground
uredirin inetd mode, e.g. to redirect SNMP requests, and timeout after 5 sec, try the following. Runs in foreground, as required for inetd services, and uses syslog for logging:
uredirused to be based on
udp_redirectby Ivan Tikhonov, but is today based on youdp by Tobias Waldekranz. Current maintainer is Joachim Nilsson.
