RE: PC CU-Seeme won't connect

Thanks to Michael Sattler for replying to several requests for
help relating to PC Cu-SeeMe not working correctly. After I
posted a notice yesterday indicating that I couldn't get PC
Cu-SeeMe to connect to any reflectors, several people wrote to
me with the same problem, several people posted a similar concern
to this listserv, and several sent possible solutions.

Apparently, there is a noticeable group of us who are use SLIP
connections and can't get Cu-
SeeMe to connect to a reflector. We keep getting "no response from
host" errors even when known active hosts are accessed.

Several have suggested missing IP addresses in the host file. In
my case, this is not the case. I've checked. Since my IP address
is assigned dynamically, I've put in the host file, thanks to the
advice of Jud Elliott and others, all probably IP addresses. This
works well with Mosaic, but apparently Cu-SeeMe needs a "name" for
the machine. That's all PROBABLE IP addresses.

So, would someone who is successully running Cu-Seeme on a PC
provide some suggestions? HOW do we "name" our machines in the
host file. I thought I'd done it, but apparently it doesn't work.
A sample host file might help, too. I now know of at least 3
users having this same problem.

I'm using Trumpet Winsock and a video spigot card.

Michael Sattler identifies himself as a "Mac bigot." On days like
this I understand. I'm running a Mac and a PC side by side. Cu-
SeeMe setup on the Mac has been smooth compared to PC setup. I"m
glad that I've got Cu-SeeMe working on the Mac side at least.

But I do need to have the PC side working. Any help would be

Hi Bob,

I'm using CUSM for the PC successfully. The problem you allude to (no response)
is not related to your HOSTS file or the naming of your machine. That produces a
different error (can't get hostname....or something like that). I think the problem is
your Internet provider. It's my understanding that CUSM uses a specific port
number when connecting to a reflector. I would suggest that your provider is
detecting and restricting your attempts to use CUSM. Here's my rationale:

I use two different Internet hosts. For some time, I have used
with a dial-up SLIP connect. CUSM works fine and I can attach to all reflectors.
When I acquired an ISDN line at home I was forced to choose an alternate provider
for this faster connect. I chose Interramp which is a division of PSI. When I first
installed my ISDN card and successfully connected, I was impressed with the
improved performance of CUSM. After a few days, without changing any
configuration on my end, I started to get the "no response from host" error. All of the
reflectors that I had connected to the day before were no longer available. Nothing
has changed on my end. Further, I can still connect to these reflectors with my
dial-up SLIP account on I've been in discussion with the support people at
Interramp ever since this happened and it's been about a month. They still haven't
admitted to having changed anything. I'm POSITIVE that they have! I will keep this
list posted as any new developments occur. I'd appreciate hearing from others that
are experiencing this problem. I'd especially appreciate you investigating the
position of your Internet provider and listing who they might be. It's my position that
when I pay for a 57K connect I should be able to send and receive data at that band
width without restriction. If I were FTPing, I would be using all the bandwidth. Let's
see if we can't find out whether there is an overt effort on the part of providers to
restrict the use of this fine program.

Best regards,
Jay Nelson
