If you had control of the environment, you could setup a sniffer on the side of the destination and see if the IP TTL is decremented as it passes through the network device. Obviously this isn't the case. You might want to try some IP fingerprinting tools, such as nmap, queso, and xprobe. Also, try pinging the device. Different devices and OS's respond with various TTLs. (I.e., TTL is set to 128 on Windows2K and 255 on most UNIXes).

I have to find a general way to find whether a remote IP box is a router or a switch. That IP box can be of any vendor. and that remote box can be located across multiple networks. ----- Original Message ----- From: Larry Letterman To: Sent: Thursday, February 28, 2002 3:07 PM Subject: RE: detect routers and switches [7:36873] > if its cisco gear, do a show cdp neighbor detail and it should show you > whats on the other end... > > > Larry Letterman > Cisco Systems > [EMAIL PROTECTED] > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of > ashish > Sent: Thursday, February 28, 2002 2:30 PM > To: [EMAIL PROTECTED] > Subject: detect routers and switches [7:36873] > > > Hi, > this question is bit vauge.But thought you guys will surely be able to help > me > out :-) > > is there any way to tell programmatically , whether a remote box is a router > or a switch. > > Thanks, > Ashish Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=36901&t=36873 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
