Add port numbers to /etc/services during installation
Added by laforge almost 4 years ago.
Updated almost 4 years ago.
Description
I think it would be great if we'd add the /etc/services snippet from Port_Numbers to /etc/services during the installation. This enables people to do telnet localhost osm-msc or the like, without having to memorize port numbers all the time.
It's a bit ugly as there is no /etc/services.d or the like, so we have to add/patch the services to the file.
In order to do that reasonable, the related postinst script should (for each service)
- check if the entry already exists, and do nothing if it does
- append the entry to the end of the file, if no entry exists yet
We could do this in bulk from libosmocore, or we could add/remove each individual line for each program we install from the respective osmo-* package.
The alternative would be to ship something like an 'osmo-telnet' client program that would have compile-time knowledge about the port numbers. As we already maintain a fork of libtelnet.git on osmocom.org, that may be an option...

'expect' script that connects to osmocom vty by name |

Related: Keith has written an expect script that connects to an osmocom telnet by name, and is also able to establish a desired logging config every time.
Attaching and pasting it. This one contains a few tweaks introduced at 36c3. We could rename to osmo-vty and install from libosmocore?
vty bsc
or
vty osmo-bsc
#!/usr/bin/expect -f

set host localhost
