I am trying to tweak my tcp wrappers settings to lock things down a bit
more and I have run into an issue in that it seems as though portmap
doesn't listen to some of the variable entries in /etc/hosts.allow. If
I make a specific entry for portmap and give it the subnet's I want it
to accept connections from it seems to work fine, if I try to give it
LOCAL or an NIS group it I see error messages in /var/log/messages
showing "connect from <IP ADDRESS> to callit(ypserv): request from
unauthorized host." Other services such as ssh, (rsh & rlogin enabled
for testing) seem to work fine. I have tried tweaking my
/etc/nsswitch.conf file but that didn't seem to help either.
anyone have any ideas? I am also curious if anyone has run into similar
issues with any other services.
Thanks!
