Just released small app for Windows platform. This app allows to decrypt type 7 password from Cisco devices as well as passwords from Cisco VPN profiles (PCF files).

Password which can be recovered using this app:

• wireless keys fro Cisco access points,
• RADIUS/TACACS shared secrets
• NTP authentication keys
• Enable passwords (NOT enable secrets, which are stored using MD5)
• enc_GroupPwd – VPN group password from PCF file
• enc_UserPassword – VPN user password from PCF file

Application also allows to store password and/or send tchem via email after decryption.

You can find app in Windows Store:

If you need to identify your public IP and have no possibility to run web browser of any kind you can use telnet.

In order to identify public IPv4:

telnet v4address.com

In order to identify public IPv6:

telnet v6address.com

Once connection is established autoresponder will show your public IP address:

This is the telnet autoresponder at v6address.com.
You have connected over IPv4.
Your IP address is 5.10.15.20

This might be helpful when using console on some *NIX systems or on the routers.

Default driver for Linksys WUSB100 Ver.2 doesn’t work on Windows 7 64-bit. Instead  of that Ralink USB RT2870 (currently MediaTek) driver can be used.

Properly working driver can be found here.

If you want to use Windows Server 2012 Datacenter on workstation/laptop (sometimes it is handy to have mobile workstation with server operating system) you might experience issues with wireless networking. Even if driver for wireless network adapter is installed you might not be able to connect to any wi-fi network.

In order to use wireless in Windows Server 2012 Datacenter additional feature has to be installed: Wireless LAN Service. This can be installed from PowerShell prompt using add-windowsfeature wireless-networking command, as shown on screenshot below:

Once installed and server rebooted make sure that WLAN AutoConfig service is started, as shown on screenshot below:

Few times in the past when I was doing some changes on Cisco devices remotely I was a victim of myself, when wrong order of commands just disconnected me from device without ability to connect back. After few experiences of this kind I discovered magic command “reload” which can help and save the day.

So, when doing changes which can impact remote terminal connection to device it’s a good idea to initiate reload before making changes. In case something goes wrong device will reboot itself and will come back with previous configuration.

lab-r01#
lab-r01#reload in 15
Reload scheduled in 15 minutes by admin on console
Reload reason: Reload Command
Proceed with reload? [confirm]
lab-r01#
*Mar  1 03:11:11.659: %SYS-5-SCHEDULED_RELOAD: Reload requested for 03:26:09 UTC Fri Mar 1 2002 at 03:11:09 UTC Fri Mar 1 2002 by admin on console. Reload Reason: Reload Command.
lab-r01#

Once everything is configured and connectivity to device was not lost we can cancel reload process.

lab-r01#
lab-r01#reload cancel
lab-r01#

It is very helpful and can save time and rescue from trouble.
