Resolution
portmapper on RHEL-5 could be secured by having it listen on localhost only. rpcbind does not offer this option. tcpwrappers and firewall can be used for securing both portmapper and rpcbind. To secure rpcbind with tcpwrappers use something like: Raw # cat /etc/hosts.allow rpcbind: 127.0.0.1 # cat /etc/hosts.deny rpcbind: ALL Root Cause The -h option for rpcbind is not expected to force rpcbind to listen on localhost only. The description from the manual page (man 8 rpcbind): Raw -h Specify specific IP addresses to bind to for UDP requests. This option may be specified multiple times and is typically necessary when running on a multi-homed host. If no -h option is speci- fied, rpcbind will bind to INADDR_ANY, which could lead to prob- lems on a multi-homed host due to rpcbind returning a UDP packet from a different IP address than it was sent to. Note that when specifying IP addresses with -h, rpcbind will automatically add 127.0.0.1 and if IPv6 is enabled, ::1 to the list. |
