98 telnet doesn't work but ftp works

Post by Zheng Su » Tue, 02 Mar 1999 04:00:00

Hi there,

In a Linux-to-Windows 98 LAN, 'c:\telnet mylinuxbox' doesn't work.  After
telnet window pops up, it dies before 'login:' prompt. The Oracle 'sqlplus'
in Window environment doesn't establish the connection with Oracle server
on Linux box as well.

But, 'c:\sqlplus orcl' in Dos works and 'c:\tnsping orcl' is normal. In
fact, Linux-to-Windows 95 works. That means my Linux box and my LAN
connection are ok. In 98 box, I can do 'c:\ftp mylinuxbox' as well. I guess
the problem in this without DUN LAN is Winsock doesn't work. Actually, the
98 box comes with a internal modem but I don't want to use it so I didn't
setup the DUN and IE now.

Any hit will be welcome.

Thank you.

subnet of A host machine with an Intel Pro/100+
