I am using PC-NFS 3.0.1 and PC-NFS Programmers Toolkit 1.00 and the
following problem has come up:

     When I try to open a TCP socket to a port by using the number
     of a service, (and not getservbyname()) it fails.

     After _some_ debugging I found that the getservbyname() function
     returned port number 5888 for telnet, that is 23 _* 256_. ( Telnet
     is usually 23, according to Assigned Numbers ) The same weird
     thing happens for other services (SMTP, NNTP ....)

     For telnet, SMTP or NNTP this is no problem, I just use getservbyname()
     or multiply, but in some cases that is not enough... When I want
     to access a port > 256, I end up with  >256 * 256 (= >64k ).. And
     since the port is declared as an "unsigned short" in the sockaddr_in-
     struct I have a problem...

     OK, a bug in the Toolkit I assumed, but then i tried the CUTCP
     telnet that uses the Toolkit, and it has no problems with port-
     numbers > 256. Confusing to say the least.. Since no source
     is available for the CUTCP software at the moment I can not find
     out what they have done to overcome the problems :-(
     (My CUTCP/CUTE is:  CUTE;2.2TN/NFS-A   dated 13th feb 1990.)

The question:

     Does anyone have any idea how i can get PC-NFS Programmers Toolkit to
     open a socket to a port > 256 ??

     Maybe someone in the CUTCP/CUTE team can share their knowledge with me?

Please answer by E-mail, or News, or fax, or phone or drop in :-)

                         Thanks in advance.
