This is a collection of leightweight Dockerfiles / images that incorporate the trbnettools. The aim is to have the TrbNet Daemon trbnetd available withtin a docker container.

You can start your container like this:

docker run -it --rm pklaus/trbnettools:ubuntu1904 /bin/bash

⁠Running trbnetd in the Container

First, start rpcbind as a daemon:

rpcbind

You can make sure, that rpcbind is listening on a local UNIX socket as well as on port 111 udp/tcp via:

rpcinfo

To start the trbnetd:

# /trbnettools/trbnetd/server/trbnetd -h
Usage: trbnetd [-h] [-f] [-i progId]
Options:
  -h    give this help
  -i    set an individual RPC-ProgId (0-255), default 0
  -f    execute as foreground process
  -V    version number

Signals:
  USR1  lock daemon
  USR2  unlock daemon

Important: The trbnetd needs the environment variable TRB3_SERVER to be set to the IP it should talk to.

# export TRB3_SERVER=192.168.111.222
# /trbnettools/trbnetd/server/trbnetd 

Now you may try to run trbcmd locally. Be sure, to set the DAQOPSERVER environment variable beforehand.

# export DAQOPSERVER=localhost
# /trbnettools/trbnetd/trbcmd i 0xffff
