Hello,
We have 3 PortServers in our SCO UNIX environment which at time show connections ESTABLISHED and everything appears to run properly.
However at times we get sporadic SYN_SENT connections, which hang up processing and they do not clear quickly so please advise on what can be done to diagnose and correct the problem.
Regards,
Mark
Hello @marklboucher . The SCO Realport driver hasn’t been supported for a few years, for instance the SCO Unix 6.0 driver was last released on 7/29/2005. The SCO 5.0.x driver would be older than that so this isn’t something we’d likely be able to assist with.
Doing a search in google, it looks like SYN_SENT was mentioned in some SCO release notes here:
The following article also came up in the search, which indicates this may be a network-related error response: What means SYN_SENT status in a socket? | by José Castro | Devsys | Medium
Our current Terminal Server product line is the Digi Connect EZ products, and we only support certain builds of Windows and Linux at this point. You can see the Release Notes from this link, if you’d like to look into our modern productline:
