I am studying for CCNA-security. I have a private test network that includes a Virtual Box with Win-XP, Win7 and Win2008 VM’s all in different subnets and with all firewalls disabled. This is a test network and don’t need to care about security. No connection to internet and the VM’s are just for supplying various protocols so I can test a Cisco ASA firewall.
To begin with I want each machine to be able to FTP, Telnet, TFTP, HTTP, HTTPs, to each other.
Today’s Problem – WinXP machine can’t Telnet to Win7 machine. XP command prompt :
“Connecting to 188.8.131.52…Could not open connection to the host, on port 23: connect failed.”
- Both machines can ping each other
- Both machines can telnet into Cisco Routers (so telnet client is working at least)
- Win7 can telnet to WinXP no problem.
- Win7 has Telnet Server and Telnet Client Enabled (seen in “Control Panel- Programs – Turn Features on/off – …..Telnet Server = on; Telnet Client= on
- Win7 Computer name: Miles-PC
- Win 7 Workgroup = WORKGROUP
- User Accounts –
Miles: Administrator / Password protected
tim: Standard User / Password Protected
- Firewall = OFF (for Domain, Private, Public) as seen in Control Panel – Firewall - Advanced
- Even the win7 default gateway (cisco router) can’t telnet directly to the Win7 PC, But here at least I am prompted for a username/password. I’ve tried using as usernames: Miles-PC\Miles; Miles-PC\tim …..but each time it says “Login failure: unknown username or bad password”.
- Firewall disabled but even still the Control Panel – Security- Firewall - “Allow programs to communicate through Windows Firewall” has Telnet selected for private/work networks. Not sure if this is even applicable if Firewall is off anyway.
This seems impossible… What am I doing wrong? Will be very grateful for anyone who can solve this.
