rpc.dracd - Dynamic Relay Authorization Control server
rpc.dracd [-i ] [ -e expire ] [ dbfile ]
rpc.dracd is the Dynamic Relay Authorization Control server. It uses the Berkeley db package to maintain a relay authorization map for sendmail, by default /etc/drac/dracd.db. POP and IMAP mail servers make an RPC call to add an entry to the authorization cache after they have authenticated each user. The daemon, rpc.dracd, adds or updates entries in the cache, and periodically expires old entries. Only trusted mail servers are permitted to communicate with rpc.dracd, as controlled by /etc/drac/dracd.allow. If this file does not exist, all local IP addresses are permitted. Allow File Format The Allow File file consists of entries of the form: netmask netaddr where both netmask and netaddr must be dotted quads.
-i Initialize the database on startup. -e expire Set the expire time limit. expire is the number of minutes the entries will remain in the database. It defaults to 30 minutes. dbfile Use a different database file name.
/etc/drac/dracd.db default database file /etc/drac/dracd.allow default allow file.
This rpc.dracd version is protected by the tcp_wrapper library. You have to give the clients access to rpc.dracd if they should be allowed to use it. To allow connects from clients of the .bar.com domain you could use the following line in /etc/hosts.allow: dracd: .bar.com You have to use the daemon name dracd for the daemon name (even if the binary has a different name). For further information please have a look at the tcpd(8) and hosts_access(5) manual pages.
