Unexpected lack of service - What security level did you install?
What isn't instantly discoverable, is that if you select level 5 security (called "higher", IIRC), then there are a set of settings applied which block activities. At install, it is suggested as a sensible option, but I struggled to grasp the implications of the setting, and how to selectively release some of the settings. This is not just done by not loading or starting some services, but a fairly sophisticated set of configurations and services are applied.
So for example all the internet services are blocked from remote servers, and some services, like ping, are blocked altogether.
Unfortunately, you have to know that there is a thing called msec (Mandriva(ehem!) Security) that does a couple of things:
- automatically reverts some changes (it was driving me mad that my permanent password setting didn't stick)
- uses a DENY ALL in the configuration files for internet services from remote services.
So for example SSH does not work even though it is all correctly configured (or rather only works locally, which rather defeats the point). After many happy hours restarting and rebooting, downloading new versions of puTTY and getting not one single useful error message aside from server unexpectedly disconnected the light dawned that there was another configuration file at work and an entry in hosts.allow solved the problem.
(Not the most comprehensive answer, but I last Linuxed at Redhat 7.2 and its all been a little distressing porting across!).
It would be useful to find a good link with some examples on how to get level 5 slackened off safely.
