SETTING UP sysmobts PACKAGE VERSIONS Depending on the code to be tested, select the stable, testing or nightly opkg feed: To change the feed and packages installed on the sysmobts edit the following files in /etc/opkg/ * all-feed.conf * armv5te-feed.conf * sysmobts-v2-feed.conf and adjust the URL. For example, to move to the testing feeds: sed -i 's/201310/201310-testing/g' /etc/opkg/*.conf Then run 'opkg update', 'opkg upgrade' and finally 'reboot'. DISABLE SERVICES To use the sysmobts together with the tester, the following systemd services must be disabled but using the mask and not using the disable option. You can use the following lines: systemctl mask osmo-nitb systemctl mask sysmobts systemctl mask sysmobts-mgr SSH ACCESS Copy the SSH public key from the system/user that runs the tester to the BTS authorized keys file so the tester will be able to deploy binaries. scp my_key.pub $sysmobts: ssh $sysmobts cat my_key.pub >> ~/.ssh/authorized_keys It is also advisable to configure the eth0 network interface of the BTS to a static IP address instead of using DHCP. To do so adjust /etc/network/interfaces and change the line iface eth0 inet dhcp to iface eth0 inet static address 10.42.42.114 netmask 255.255.255.0 gateway 10.42.42.1 Set the name server in /etc/resolve.conf (most likely to the IP of the gateway). ALLOW CORE FILES In case a binary run for the test crashes, we allow it to write a core file, to be able to analyze the crash later. This requires a limit rule: scp install/osmo-gsm-tester-limits.conf sysmobts:/etc/security/limits.d/
