DATALOC SSHDEL address
DATALOC SSHLIST address
DATALOC HOST
|
ADD |
adds an entry to the client routing table; the entry maps a group name to a server's IP address |
|
DEL |
deletes an entry from the client routing table |
|
LIST |
lists the client routing table (default) |
|
SSHADD |
adds an entry to allow tunneling for ADDE requests |
|
SSHDEL |
deletes entry that allowed tunneling for ADDE requests |
|
SSHLIST |
lists the user name and file for tunneling address |
|
HOST |
refreshes the name server lookup for hosts; must be run if a server's numeric IP address is changed |
|
group |
group name (no default for ADD and DEL; default=all groups for LIST) |
|
address |
IP address of the server; specify LOCAL-DATA for the local server |
|
user |
user name on remote host used for tunneling |
|
file |
file name containing SSH keys for tunneling to a remote host |
|
GATEway= |
IP address of the computer, router or other device acting as a gateway between the client and server (specify this keyword only if required by your network configuration) |
DATALOC manages the client routing table, which links ADDE groups to IP addresses of servers. When you enter an ADDE command, the client routing table is scanned to locate the server that will receive the data request. When the server receives the data request, it scans its own mapping table to determine which data the client is requesting. If an ADDE command specifies a group name that is not in the client routing table, the data request is sent to the local server.
You cannot assign the same group name to more than one server because the ADD option overwrites an existing group name without warning. You may, however, assign more than one group name to a server.
The SSHADD, SSHDEL and SSHLIST options should be used only if you access datasets on a remote server (specified in the address parameter) that uses SSH tunneling. Both the client and remote server (or gateway, if using the GATEway= keyword) must have an SSH key file set up for automatic login on the remote server, and its SSH daemon must be listening for requests.
DATALOC
This entry lists the client routing table.
DATALOC ADD MYDATA LOCAL-DATA
This entry modifies the client routing table so that commands requesting data from a dataset in the group MYDATA are routed to the local server.
DATALOC ADD RTSERV WEATHER.SSEC.WISC.EDU
This entry modifies the client routing table so that commands requesting data from a dataset in the group RTSERV are routed to the server at the IP address WEATHER.SSEC.WISC.EDU.
DATALOC ADD RADAR 123.456.789.012
This entry modifies the client routing table so that commands requesting data from a dataset in the group RADAR are routed to the server at the IP address 123.456.789.012.
DATALOC LIST RADAR
This entry lists the client routing table entry for the group RADAR.
DATALOC DEL RADAR
This entry deletes the client routing table entry for the group RADAR.
