.TH TRAMPOLINE 8 .SH NAME trampoline \- forward incoming calls to another address .SH SYNOPSIS .B aux/trampoline [ .B -9 ] [ .B -a .I altaddr ] [ .B -m .I netdir ] [ .B -t .I timeout ] .I addr .SH DESCRIPTION .I Trampoline can be used in a service file (see .IR listen (8)) to link an incoming call to another address that provides the service, typically on another machine. .PP .I Trampoline dials .I addr and copies data between that connection and its own standard input and output. .PP The options are: .TP .B -9 The connection carries only 9P messages. In this case .I trampoline will relay whole messages at a time. .TP .BI -a " altaddr Dial .I altaddr and relay between the two network connections, ignoring standard input and output. .TP .BI -m " netdir Restrict forwarding to particular machines. .I Netdir must be the incoming call directory. .I Trampoline finds the caller's MAC address .I m and checks that .IR ndb (6) contains an entry with .BI ether= m and the attribute .BR trampok . If no such entry is found, the call is rejected. .TP .BI -t " timeout Terminates the connection after .I timeout milliseconds of inactivity. .PD .SH FILES .TF /sys/log/trampoline .TP .B /sys/log/trampoline logs rejected calls .SH SOURCE .B /sys/src/cmd/aux/trampoline.c .SH SEE ALSO .IR dial (2), .IR listen (8)
