A Challenging Situation : i hope the moderators will respond to this problem..

I have the following situation :

i have 4 Unix Sco servers, one Windows 2000 server, and an ADSL internet connection. All the servers, that is the 4 unix and the windows server have real static IPs supplied by my ISP.

the servers are connected to a Switch , the switch is connected to an ADSL Alcatel SpeedTouch 510 router, which in turn is connected to the telephone line. the Router has a real static IP gateway.

if i log into one of my local unix servers, i can telnet and ftp to another unix server in another country(another network), BUT here is the problem : i can ping from that remote server all of my local unix servers, but i cannot telnet ot ftp or rlogin to any of them, so why is that?? if a remote server can ping my local servers why cant the remote server ftp or telnet or rlogin my local servers????? is it possible that my isp should enable the specific ports for telnet and ftp and rlogin???? or is it a problem related to some Unix Sco netywork configuration in my local servers???

i would appreciate ur help

xserver

Xserver(1)						      General Commands Manual							Xserver(1)

NAME

       X - X Window System display server dispatcher

SYNOPSIS

       X [ option ...]

DESCRIPTION
:
       Hewlett-Packard	supports  two  X  servers on HP-UX platforms, the Xhp X server which supports HP VISUALIZE graphics devices and the Xf86 X
       server which supports all other graphics devices.  These X servers are delivered as /usr/bin/X11/Xhp and /usr/bin/X11/Xf86.

       The X dispatcher determines which X server to launch based on the available graphics devices.  The control file /etc/X11/Xstart can provide
       additional  guidance to the X dispatcher.  The control file allows the user to specify which X server to start for given display connection
       numbers. The only X servers supported by the X dispatcher are Xhp, Xf86 and Xvfb.  If no Xstart	file  exists,  the  dispatcher	loads  the
       appropriate  X server for the graphics device in the system.  HP-UX does not deliver the /etc/X11/Xstart file.  This file can be created by
       using the SAM/SMH utility.

OPTIONS

       If the X dispatcher is invoked with no arguments, the display connection is assumed to be :0.  The X dispatcher checks for display  connec-
       tion  options  and, if found, uses that display connection number when it checks the Xstart file.  All other options are passed on to the X
       server when it is started and it is the X server's responsibility to validate these options.  Not all options may be supported  on  both  X
       servers; refer to Xhp(1) and Xf86(1) to verify supported options for each X server.

RETURN VALUE

       None

Xstart EXAMPLES
       The control file syntax is the X server to start followed by the display connection number.  Valid entries take the form of:

       Xhp :0				       Start the Xhp X server on display connection 0

       Xf86 :10 			       Start the Xf86 X server on display 10

       /usr/bin/X11/Xhp :5		       Start the Xhp X server on display connection 5

       /usr/bin/X11/Xvfb :7		       Start the X Virtual Framebuffer server on display connection 7

FILES

       /etc/X11/Xstart			       Dispatcher control file.

       /var/X11/Xserver/logs/Xstartup.N.log    X dispatcher log file for display N.

SEE ALSO

       X(1), Xhp(1), Xf86(1)

STANDARDS CONFORMANCE

       See the appropriate section in Xhp(1) or Xf86(1).
