In case any one is interested, this is what i found so far:
- the client is supposed to connect to port 3001 on the xcat host;
- it uses an openssl connection to encrypt / certify the connection
between the client and the host;
- by default, it will try to load the following files:
- key file: /root/.xcat/client-cred.pem
- cert file: /root/.xcat/client-cred.pem
- ca file: /root/.xcat/ca.pem
- the requests and responses are XML based, here's an example on how
to communicate with the host (doing the same as running a "xcatclient
getrvidparms vm1" command):
[root@xcat ~]# openssl s_client -connect localhost:3001 -crlf -key
/root/.xcat/client-cred.pem -cert /root/.xcat/client-cred.pem -CAfile
/root/.xcat/ca.pem
CONNECTED(00000003)
depth=1 CN = xCAT CA
verify return:1
depth=0 CN = l01.ac
verify return:1
