Enable 8.3 naming convention on Windows 2008 R2

I ran into an issue recently where the application required me to enable the 8.3 naming convention on a Windows 2008R2 server.

To achieve this, simply issue the following command from the CLI.

fsutil.exe 8dot3name set 0

The change should be immediate.

Configure NTP - Cisco switch

You will want to be sure that the time on your Cisco switches is accurate.  To do this you can enable NTP and have your switch poll a time server to keep accurate time, just make sure you have access to a time server.

One thing you need to do is set your timezone, I am central time which looks like this:

Switch(config)# clock timezone CST -6

Next, if you recognize daylight savings time, you’ll want to enable that:

Switch(config)# clock summer-time CDT recurring

Next, point at your time server:

Switch(config)# ntp server

This may take a minute to update, but you can verify you now have the proper time you can type:

Switch# show clock

Restore factory default - Cisco ASA 5505

I use a little ASA 5505 for testing from time to time and sometimes I get it to the point where I just want to set it back to factory default.  To do this is rather simple, the following lines will get you there.

From a console connection perform the following.

'enable'
'conf t'
'config factory-default'
'write mem'
'reload'

You should now be able to use the default address 192.168.1.1 to get started.

tcpdump - filter destination port

There are times when you may need to do some network troubleshooting on a *nix box and only have access to tcpdump.

One handy thing to do if your troubleshooting an application is to filter on the destination port so you can zero in just on that application data.  Here is how you could build a filter to capture data based on the destination port 8080 going over interface eth0.

tcpdump -i eth0 dst port 8080
