/etc/services¶
If you are continuously working with osmocom software, as a convenience helper, you might add something like
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
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.
