What does
+@foo_hosts username
mean in a user's .rhosts file?
I presume it is defining a group of hosts in some way, but I can't figure out where to look for the definition of @foo_hosts. I found the name foo_hosts mentioned in the output of ypcat netgroup.byhost but not in a way that seems to associate it with any list of hosts.
uname reports SunOS 5.8
This is NIS.
The netgroup database is kept on the NIS master server in the file /etc/netgroup or /usr/etc/netgroup. This file consists of one or more lines that have the form:
groupname member1 member2 ...
After this file is updated (or any other NIS database file for that matter) to make the changes live you have to run a second command, makedbm which might be /etc/yp/makedbm or /usr/etc/yp/makedbm
