Telnet is more secure than RSH, as secure as FTP, and less secure than SSH or Secure Socket Layer (SSL). Telnet is used for administrative control of your storage system and uses TCP connections on port 23.

This port appears in a port scan only if the SecureAdmin software is installed on your storage system. Secure Shell (SSH) protocol is a secure replacement for RSH and runs on TCP port 22. Some ports appear in a port scan but are not listed in the /etc/services file, for example, TCP ports 22 and 443.įile Transfer Protocol (FTP) uses TCP ports 20 and 21. Some ports on the storage system are NFS-enabled. The NNTP and TTCP ports are not used by your storage system and should never be detected by a port scanner. There are several services that are not currently listed in the /etc/services file.

2.Although some port scanners are able to identify storage systems as storage systems, other port scanners report storage systems as UNIX systems if they support NFS or as Windows systems if they support CIFS.

If you have access to a non-元 switch, you can test this by creating another vlan and assign an ip address to it, do "no shut", then do "sh ip int bri", you'll see that it is up/down. Only one management VLAN can be active at a time. By default, the active management VLAN is VLAN 1, but you can designate any VLAN as the management VLAN using the Management VLAN window. This connection supports a VSM, SNMP, and Telnet session. The management VLAN is used to establish an IP connection to the switch from a workstation connected to a port in the VLAN. The answer you can looking for is because of the Management VLAN Then on which port does this telnet server running because there is no concept of ports in ROUTERS & switches ? The concept of PORT (telnet = 23) is in computers only. how can an application layer program run in layer2 & 3 ?Ģ. implies there is a TELNET server running running in switch and router (by default on port 23).ġ. We can connect to both switch and router using Telnet. and a telnet client(also in application layer) connects to the server. and It needs a Telnet server(in application layer) running on remote port. There can be many different ports assigned to an IP address therefore many applications can be used at once

Ports are used to allow an specific application to talk to an IP address. The router has a telnet server running (application) that accepts communications on port 23. The router will once again see the IP address of the packet is the same as the routers IP address so it strips the IP address off and finds the telnet application

The router will then stip the MAC address of and check the IP address The router will see the MAC address and realize that packet is trying to access its mac address. This frame will then be sent on the wire to the router. Once you know the MAC address that will encapsulate the IP address and Telnet application. With the IP you now have the logical address of the Router, but you will need the MAC (layer 2) in order to communicate to the Routers NIC card. That information will then be encapsulated around the telnet applicaiton In order to send information to the router you will need the IP address (layer 3) of the Router. The telnet application is not being run at layer 2 and 3.
