Portmap man page contradicts itself
Last modified: 2008-05-01 11:37:56 EDT
The entire mention of portmap's TCPWRAPPERS in the man page of portmap
This portmap version is protected by the tcp_wrapper library. You
give the clients access to portmap if they should be allowed to use
To allow connects from clients of the .bar.com domain you could use
following line in /etc/hosts.allow:
You have to use the daemon name portmap for the daemon name (even if
binary has a different name). For the client names you can only use
keyword ALL or IP addresses (NOT host or domain names).
For further information please have a look at the tcpd((8)),
low((5)) and hosts_access((5)) manual pages.
Notice how .bar.com is not an IP address? This example needs to be fixed,
as it misleads people into thinking that names are allowed. Please at
least change the man page for RHL 7.0
Fixed in portmap-4.0-31. FTR, yes you can use host names and domain names.
