 h2. Port numbers for test programs 

 In addition to above ports, when configuring --with-external-tests, the 'make check' build phase might be using below port numbers for VTY/CTRL/... testing. No production program will use these ports. 

 |_.L4|_.Port Number|_.Purpose|_.Software| 
 |TCP | 42042 | telnet (VTY) | libosmocore/tests/logging/logging_vty_test | 
 |TCP | 42043 | telnet (VTY) | libosmo-sccp/tests/vty/ss7_asp_vty_test | 

 h1. /etc/services 

 If you are continuously working with osmocom software, as a convenience helper, you might add something like 

 <pre> 
 osmo-pcap-client          4237/tcp 
 osmo-pcap-server          4238/tcp 
 osmo-stp                  4239/tcp 
 osmo-pcu                  4240/tcp 
 osmo-bts                  4241/tcp 
 osmo-bsc                  4242/tcp          osmo-nitb 
 osmo-mgw                  4243/tcp          osmo-bsc_mgcp 
 osmo-bsc_nat              4244/tcp 
 osmo-sgsn                 4245/tcp 
 osmo-gbproxy              4246/tcp 
 osmocombb                 4247/tcp 
 sysmobts-mgr              4252/tcp 
 osmo-gtp-hub              4253/tcp 
 osmo-msc                  4254/tcp 
 osmo-sip-connector        4256/tcp 
 osmo-hlr                  4258/tcp 
 osmo-ggsn                 4260/tcp 
 osmo-cbc                  4264/tcp 
 osmo-uecups               4268/tcp 
 osmo-e1d                  4269/tcp 
 </pre> 

 to the end of your @/etc/services@ file.    This will allow you to do something like @telnet localhost osmo-bsc@ rather than having to remember that the number was 4242.
