130 IOLAN SDS/SCS/STS User’s Guide, Version 3.6
Advanced Tab Field Descriptions
Configure the following parame ters:
Authenticate User Enables/disables login/password authentication for users connecting from the
network.
Default: Disabled
Enable TCP
Keepalive Enables a per-connection TCP keepalive feature. After the configured number
of seconds, the connection will send a gratuitous ACK to the network peer,
thus either ensuring the con necti on stays active OR causing a dropped
connection condition to be reco gni zed.
This parameter needs to be used in conjunction with Monitor Connection
Status Interval parameter found in the Serial, Advanced, Advanced Settings
tab. The interval specifies the inactivity period before "testing" the connection.
Default: Disabled
Enable Message of
the Day (MOTD) Enables/disables the display of the message of the day.
Default: Disabled
Enable Data
Logging When enabled, serial data will be buffered if the TCP connection is lost. When
the TCP connection is re-established, the buffered serial data will be sent to its
destination (this option is not available when Monitor DSR, Monitor DCD, or
Multihost is enabled).
The data buffer is 4K for desktop models and 32K for rack mount models. If
the data buffer is filled, incoming serial data will overwrite the oldest data.
Default: Disabled
Idle Timeout Use this timer to close a connection because of inactivity. When the Idle
Timeout expires, the IOLAN will end the connection.
Range: 0-4294967 seconds (about 49 days)
Default: 0 seconds so the port will never timeout
Session T im e out Use this timer to forcibly close the sessi on/connection when the Session
Timeout expires.
Default: 0 seconds so the port will never timeout
Range: 0-4294967 seconds (about 49 days)
