Hello All,
RE: Telnet buffer pools

This is a follow-up to past discussions about telnet "sucks wind" //8-) with
INETD reporting error "Could not initialize data in path with TCP" or Telnet
hangs at ":".

Some folks might have not seen the above conditions and may be blissfully
unaware that telnet uses "Buffer Manager" buffer pools just like you see in
nettool resource for the LAN drivers and TCP... This is for those of you who
have painfully learned the truth.

An enhancement to nettool has been implemented to display these pools as
well as several new fixes to buffers leaked by Telnet.

Here is what the enhancement to nettool looks like:

: nettool.net.sys;info="res;di;quit"

 18    TELNET    PTOD     (G)  Negot   Buf Pool    0      1   2048 :)

Note: The Telnet buffer pools are created at the first telnet connection
attempt and will not be displayed in nettool until after they are created.

This enhancement is available as BETA TEST at the HP Response Center as per
SR 8606-388358 in patches NSTHDC7 for C.65.00, NSTHDC8 for C.70.00 and
NSTHDC9 for  C.75.00.
