[Dxspider-support] Incoming telnet connections getting blocked after about 30 minutes

[G3YPP]

Hi  Dirk,

I am coming to the conclusion that there is a bug in my router –a  Huawei HG635.   Having done more research this seems to be a relatively common problem with this router.   Once the ports “block” to outside connections, sites such as “Shields Up” show the ports to be “Stealthy” ie they do not respond to connection requests.    This is an annoying intermittent problem; external users can sometimes connect all day – and then the incoming ports block.  After a router reboot all is well for a period.

I should say that this does not affect the outbound connections to partner nodes.   Frustrating or what 😊  

The DX Spider node  is always completely accessible right across my LAN by all devices whether connected by Wireless or ethernet.    (The DX Spider is connected by ethernet).    Hence my now being pretty certain that this is a router problem albeit a new fault.  

However, for completeness and interest, my node is running on a Raspberry Pi 3B+
Raspberry Pi running Raspbian 10 (Buster)
Perl version  5.28
DX Spider Cluster version 1.57 (build 279 git: mojo/841b6104[r]) on Linux

I don’t think the Pi can block the external internet – can it?

Regards

Mike

When you say "blocked" do you mean they just hang or are actively 
"connection reset by peer" or some such message.

What operating system, which perl and what build of DXSpider are you 
running (sh/version)
