Managing FTP connections

Setting the FTP connection threshold

The FTP connection threshold (ftpd.max_connections_threshold) triggers a system log entry when the number of FTP connections approaches the maximum number of allowed FTP connections (ftpd.max_connections).

To set the FTP connection threshold, complete the following step.

Step	Action
1	Enter the following command: options ftpd.max_connections_threshold n n is the percentage (0 through 99) of the value specified for `ftpd.max_connections`. By default, this threshold is set at 0 percent (off). If the threshold SNMP trap has been set, the trap is triggered each time the value is exceeded.

Step

Action

Enter the following command:

options ftpd.max_connections_threshold n

n is the percentage (0 through 99) of the value specified for ftpd.max_connections.

By default, this threshold is set at 0 percent (off). If the threshold SNMP trap has been set, the trap is triggered each time the value is exceeded.

Available SNMP traps for FTP service

You may want to generate SNMP traps to monitor the following storage system information on your client:

When concurrent connections reach the ftpd.max_connections_threshold
When concurrent connections reach the ftpd.max_connections
When the FTP daemon process stops due to an error

Initializing SNMP traps

To initialize an SNMP trap on the storage system and a UNIX client, complete the following steps.

Step	Action
1	At the storage system console, enter the following: `snmp init 1` `snmp traphost add [`hostname`]`
2	Start `snmptrapd` on the UNIX client that is to receive the trap information. At the client command line, enter the following: `r snmptrapd -P`

Step

Action

At the storage system console, enter the following:

snmp init 1

snmp traphost add [hostname]

Start snmptrapd on the UNIX client that is to receive the trap information. At the client command line, enter the following:

r snmptrapd -P
