How to connect to a counting house computer

Use ssh or putty to connect to hallgw ( need to use cryptokey ) need to forward a local port : example 5902 to an unused port on hallgw 25342 in putty
or in ssh : ssh -L5902:localhost:25342 username@hallgw.jlab.org

To avoid conflicts : lets day 25342 for Victoria , 25343 for Austin and 25344 for Dillon ( though feel free to use any other numbers as long it is not already used )

once in hallgw ssh to the computer you want to connect :

example

ssh -L25342:localhost:5935 adaq@adaq2

once connected you can launch your vnc client

1. Farm Locations:
   • Full waveform GMn data can be found in the following location on the farm. Note that the data, despite its size, is sparse and better distributions on elastic tdc/adc/energy can be obtained with larger data sets. /lustre19/expphy/volatile/halla/sbs/seeds/rootfiles
   • The pass 0 replays of GMn SBS4 data can be found in the following location. /work/halla/sbs/sbs-gmn/pass0/SBS4/LH2/rootfiles
