Manually starts the SMTP sender queues (not the receiver [server]).
Related commands: SHOW MAIL, ENABLE SERVICE SMTP, SHOW CONFIGURATION SMTP
Requires SYSPRV or BYPASS privilege.
SMTP consists of the sender and the receiver. Start the sender before you enable the receiver.
Do not issue this command unless SMTP has been configured (with the SET CONFIGURATION SMTP command).
TCPIP> START MAIL
Starts the SMTP sender.
Starts dynamic routing with ROUTED or GATED. If you want to change from one to the other, you must stop the current dynamic routing daemon then start the desired daemon. You cannot run both GATED and ROUTED at the same time.
Related commands: STOP ROUTING, SET GATED
START ROUTING [/GATED ]
[ /LOG ]
[ /SUPPLY[=DEFAULT] ]
Enables the gateway routing daemon (GATED).
If you enable dynamic GATED routing, you will be able to configure this host to use any combination of the following routing protocols to exchange dynamic routing information with other hosts on the network:
- RIP (Routing Information Protocol), Versions 1 and 2
- RDISC (Router Discovery Protocol)
- OSPF (Open Shortest Path First)
- EGP (Exterior Gateway Protocol)
- BGP (Border Gateway Protocol), BGP-4
- Static routes
/SUPPLY[=DEFAULT]Optional. Applies only to ROUTED. Do not use with /GATED.
Broadcasts routing information to other hosts in 30-second intervals.
If you specify /SUPPLY=DEFAULT, the local host supplies the default network route.
/LOGOptional. Applies to ROUTED. Do not use with /GATED.
Logs routing activity to
Default: No logging.
TCPIP> START ROUTING /GATED
Starts GATED dynamic routing on the running system.
TCPIP> START ROUTING
Interactively starts ROUTED dynamic routing on the running system.
TCPIP> START ROUTING /SUPPLY
Immediately starts ROUTED dynamic routing. The local host both broadcasts and receives network routing information.
