Download POS and set environment
  mkdir TriDAS_lea
  cd TriDAS_lea
  scl enable devtoolset-8 bash

  cd ..

Download and compile FecSoftware 
  git clone https://gitlab.cern.ch/cmspos/FecSoftware.git FecSoftwareV3_0
  cd FecSoftwareV3_0
  make -j 8
  make install

Compile POS
  cd $BUILD_HOME/pixel
  make Set=pixel -j 8
  make install
  cd $BUILD_HOME/pixel/PixelRun
  mkdir Logs Runs

Note: I encountered compilation errors and had to add the line:
  #include <TSystem.h>
to these two header files:
  TriDAS_lea/pixel/PixelUtilities/PixelRootUtilities/include/PixelHistoThreadFrame.h
  TriDAS_lea/pixel/PixelUtilities/PixelRootUtilities/include/PixelHistoThreadFrameWithArgs.h


=== Installation of network card on Centos7 ===

get name of new network card
  bash
  ifconfig -a

gives **enp4s5** for this network card, yours could be different

create file 
  /etc/sysconfig/network-scripts/ifcfg-enp4s5 (choose the right name for your card)

with this content:

  HWADDR=90:E2:BA:F7:6B:F7
  TYPE=Ethernet
  PROXY_METHOD=none
  BROWSER_ONLY=no
  BOOTPROTO=none
  DEFROUTE=no
  IPV4_FAILURE_FATAL=no
  IPV6INIT=yes
  IPV6_AUTOCONF=yes
  IPV6_DEFROUTE=no
  IPV6_FAILURE_FATAL=no
  IPV6_ADDR_GEN_MODE=stable-privacy
  NAME="enp4s5"
  UUID=8c87de7c-ab31-3faa-8480-3c9571cad2af
  ONBOOT=yes
  AUTOCONNECT_PRIORITY=-999
  IPADDR=192.168.0.1
  PREFIX=23
  GATEWAY=192.168.0.1

(change the HWADDR, the NAME and the UUID to fit your network card)

restart the network service

  sudo systemctl restart network.service


check the ip address change

  ifconfig -a

the network card should now have the ip address 192.168.0.1 with the netmask 255.255.254.0

install the dhcp daemon and wireshark

  sudo yum install dhcpd wireshark


install the rarp daemon using the instructions from https://wiki.physik.uzh.ch/cms/nanocrate:nanocrate
  bash
  #!/bin/bash
  sudo wget http://download-ib01.fedoraproject.org/pub/epel/6/x86_64/Packages/r/rarpd-ss981107-42.el6.x86_64.rpm
