==== Summary UDP via ICMP transport daemon ==== Contents * Repository: [Subversion|http://svn.cmeerw.net/src/icmptransd/] ==== Synopsis {{{ icmptransd [-f] [-v] [-b bindport] [-c connectport] [-i icmpid] [-p pidfile] [-r remoteaddr] [-s setuid] [-t icmptype] [-u udpaddr] }}} * =-f= .. foreground * =-v= .. verbose * =-b= .. UDP port to bind to * =-c= .. UDP port to connect to * =-i= .. ICMP id * =-p= .. PID file * =-r= .. remote IP address for ICMP packets * =-s= .. set UID * =-t= .. ICMP type * =-u= .. remote IP address for UDP packets ==== ICMP Payload Bits 0-15 | ICMP Type | ICMP Code (= 7) Bits 16-31 | Checksum Bits 32-47 | ICMP id Bits 48-63 | Sequence Nr ==== Usage Example Suppose your server has IP address 10.0.0.1 and you have a daemon listening on UDP port 22222 running on that machine. * Run icmptransd on the server machine: {{{ icmptransd -p /var/run/icmptransd.pid -s nobody -c 22222 -u 10.0.0.1 -i 33333 }}} * Run icmptransd on the client machine: {{{ icmptransd -p /var/run/icmptransd.pid -s nobody -b 11111 -r 10.0.0.1 -i 33333 }}} Finally, configure your UDP client to connect to 127.0.0.1, port 11111 (instead of 10.0.0.1, port 22222).
