[comp.unix.wizards] UNIX-PC to VAX to SUN

phil@bcscal.UUCP (Phil Kemp) (01/26/89)

I have already posted this to comp.sys.sun and comp.protocols.tcp-ip and
comp.os.vms but I thought some one might have done somethin like this in
the UNIX world...

I am using a UNIX-PC connected to a VAX as a terminal, via a hardwire
connection to a multiplexor, and then invoking telnet to log in to a SUN
attached to a TCP/IP network linking everthing together. ( except my PC )

The problem I'm having is that while I can do file transfers via kermit
to the VAX with no problem, I cannot pass data to the SUN in anything
but the smallest amounts. cu's put and take seem to overrun the SUN's
tty interface buffers, Kermit will simply not work, I cannot even get
the files started and Xmodem/Zmodem will not work either.

I suspect the problem to be in the telnet protocol's handling of data
and packet sizes. I have tried setting binary and charmode on telnet to
no avail.

Has anyone done anything like this before and been successful? My
objective is get uucp working between my machine and the remote SUN. 
If there is a good reference on the innards of Telnet  between the VAX
and the SUN, I would sure like to know about it.

Please E-mail any help to me and I will try and summarize if there is a
decent solution.

Thanks in advance.

Yes, I do something similar all the time: PC --> PACX --> VAX --> SUN -->
SUN ...   or  PC--> Gandalf SMUX --> terminal server DEC 100 --> VAX -->
SUN --> ... Kermit between the PC and the (very!) remote Sun works just
fine for text files (binary a bit dubious but not really necessary)
HOWEVER, we use DNI between the VMS VAX and the Sun, and rlogin to
get to other Suns without DNI. Try rlogin instead of telnet ??.

Sorry, the return path is so tortuous I have to post it to the net.

Did you try setting explicit parity on Kermit for both the VAX and Sun??  I
haven't tried this particular combination, but based on net recommendations
when I find Kermits that don't wanna talk I try set parity even on each end
and that usually works.
