[Dxspider-support] User Timeout?

[Steve - AA4U]

Dirk,

I've been running a DXSpider node for a long time. Over the past couple 
of years as more telnet user programs pop-up, I've noticed an increase 
in frequent disconnects during minimal DX Spot activity. I'm certain (in 
this case) this to either due to the user's ISP connection or not 
setting their "keep alive" timer within the software.  I've always sent 
an email to the user and tried to coach them into correctly setting the 
"keep alive" parameters, etc. However, recently I got to wondering about 
some of the inner workings of DXSpider regarding telnet users:

- Is there a telnet timeout built-in? What is the default?
- If not, could there be one configurable by the SysOp?

- What does the following line in \spider\local\ DXVars.pm control:

# the interval between unsolicited prompts if not traffic
$user_interval = 11*60;

Thank you in advance.
