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.
