Enabling XDMCP in Solaris 10

Solaris 10 is secure by default and starts services on localhost instead of system name or all hosts(*) . Due to that if you try to connect to server over xdmcp using exceed on demand or something you won’t get connection. For that we need to use following method to fix it.

if you issue ps on dtlogin. It might come up like this and listens on udp port 0 instead of 177.

#ps –ef |grep –i dtlogin

/usr/dt/bin/dtlogin -daemon -udpPort 0
You can change the above behaviour by using svccfg and change the properties.
#svccfg -s cde-login setprop 'dtlogin/args=""'

#svcadm restart cde-login # or #svcadm enable -r cde-login


After these system should respond to xdmcp broadcast queries.  Also if you want to disable the default security option you could give a try with netservices { open | limited }
