Re: [foxboro] R: DNBI Cabling for long Distance

We have experienced the same problem when we switched to version 7.1.1 and =
used DBNTs to connect the 51F boxes to the nodebus. (This by the way is no =
longer supported by Foxboro and we will be changing to RCNIs and NCNIs).  =
Are you saying that even connecting the version 7.1.1 stations together =
with RCNIs, NCNIs and switches that you still experience the slow rlogin =
and telnet sessions?

We connected all of our stations together via the second ethernet port and =
now use that connection to move data with rlogin and telnet and do not =
experience the slow connections that were introduced with version 7.1.1 =
over the nodebus.

A very known problem.
Try telnetting from your AW to a WP on the switched network (V7.x).=3D20
That's near impossible.
I don't think it has anything to do with the cable length.=3D20
Looks to me more like a switch problem. It just looses the path or so.
I have great issues between CP's and the AW trying to utilise SENDMSG to
execute programs on the host and then to get some data back to the CP.
This fails on a regular basis.

Jaime,

It's my understanding that this is a known issue.  We see the same
behavior when using rlogin to a V7.1.1 workstation - we have short UTP
cables (2 meters) and experience these problems. =3D20
