From the strcpy(3) man page, the following warning is given: The strncpy() function is similar, except that at most n bytes of src are copied. Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not be null-terminated. The current corosync code base does not take this warning into account when using strncpy, potentially resulting in non-null terminated strings.

Quick start guide. ================== CTS: Cluster Test System The CTS uses a test driver node(TDN) to drive the execution of the test software. The CTS also uses 2 or more test target nodes(TTN) to run the test cases. The CTS software requires atleast 3 nodes 1 of which acts as a TDN and the remaining acting as TTNs. The dependencies of the TDN include Pacemaker and Augeas. On the single TDN, it is recommended at this time to install pacemaker from source so that the CTS from Pacemaker remains compatible with the current working version of the CTS components within Corosync (currently you will the devel branch http://hg.clusterlabs.org/pacemaker/devel/). 2] ssh access -------------------------------------------------------------------------------- CTS requires login-less root access to the CNs. so if my CN is called "node32" # ssh node32 should not ask for a password and result in a root shell. To enable this behavior, create a ssh key with the command ssh-keygen. When it prompts for a password, enter an empty field. It will create a file called ~/.ssh/id_dsa.pub. Copy that file to the TTNs into /root/.ssh/authorized_keys. Ensure permissions are 700 on /root/.ssh. Test ssh into the machine works without a password from the TDN. 3] Install augeas on the TDN -------------------------------------------------------------------------------- yum install augeas 4] Configuring corosync for CTSs testing -------------------------------------------------------------------------------- ./configure --enable-testagents --enable-augeas --enable-debug and then install it on the TTN. 5] run CTS -------------------------------------------------------------------------------- cd <your-corosync-src-dir>/cts sudo ./corolab.py --nodes "n1 n2 n3"
