In the watchdog script you could issue this command : asterisk -r -x "rpt showvars <NODE>" (where <NODE> is you node number of course, and include the quotation marks) Doing this with my node connected to 2135 gives this result: Variable listing for node 27783: RPT_TXKEYED=0 RPT_NUMLINKS=34 RPT_LINKS=34,TW3SBA,T2135,T8701,T27296,T2122,T27356,T27262,T27349,T2121,T27355,T27261,T27348,T2377,T27657,T27658,T27690,T27354,T27258,T27499,T27701,T27572,T27372,T27373,T2341,T27854,T2242,T27653,T27702,T27672,T2300,T27635,T27470,T27665,T27266 RPT_NUMALINKS=2 RPT_ALINKS=2,W3SBATU,2135TU RPT_ETXKEYED=0 RPT_RXKEYED=0 RPT_AUTOPATCHUP=0 -- 8 variables Which could be parsed for the node number that you want to reject. Then within the output of : asterisk -r -x "rpt stats <NODE>" the last DTMF command executed is shown. For example : ************************ NODE 27783 STATISTICS ************************* Selected system state............................: 0 Signal on input..................................: NO System...........................................: ENABLED Parrot Mode......................................: DISABLED Scheduler........................................: ENABLED Tail Time........................................: STANDARD Time out timer...................................: ENABLED Incoming connections.............................: ENABLED Time out timer state.............................: RESET Time outs since system initialization............: 0 Identifier state.................................: CLEAN Kerchunks today..................................: 0 Kerchunks since system initialization............: 0 Keyups today.....................................: 63 Keyups since system initialization...............: 1190 DTMF commands today..............................: 2 DTMF commands since system initialization........: 6 Last DTMF command executed.......................: 32135 TX time today....................................: 00:01:38.292 TX time since system initialization..............: 01:10:31.702 Uptime...........................................: 36:58:08 Nodes currently connected to us..................: W3SBA, 2135 Autopatch........................................: ENABLED Autopatch state..................................: DOWN Autopatch called number..........................: N/A Reverse patch/IAXRPT connected...................: DOWN User linking commands............................: ENABLED User functions...................................: ENABLED Parse and use that line to construct a disconnect command to nullify the last . Then maybe play an "conflicting node" voice announcement. Bob, WB3AWJ Loganville, PA
