The Cisco IOS ‘more’ command

A co-worker was on a call with TAC today and noticed the Cisco engineer using the more system:running config command.

It turns out that more system:running config is the replacement for write terminal and was introduced somewhere around IOS 12.1 from what I can tell.

It also displays the same information as show running-confiig with one exception, more system:running-config will display VPN pre-shared keys in clear text.

There were a number of new file management commands introduced in IOS 12.1 and 12.2.  Check out the Cisco IOS Configuration Fundamentals Command Reference pdf for more information.

The more command also works on an ASA.  Here’s the output from an ASA5505:

asa5505# more ?

/ascii   Display binary files in ASCII
/binary  Force display to hex/text format
/ebcdic  Display binary files in EBCDIC
disk0:   File to display
flash:   File to display
ftp:     File to display
http:    File to display
https:   File to display
smb:     File to display
system:  File to display
tftp:    File to display

Exporting a Windows Server 2003 DHCP Database

This is the quickest method I’ve found to move a DHCP server from one Windows 2003 server to another.

First, make sure you have the DHCP server service installed on the destination server.

Make sure the log in account you are using for the export/import has local admin privileges.

From the command prompt on the source server enter the following:

netsh dhcp server export c:\dhcpdb.txt all

This exports the database to a text file named dhcpdb.txt.

Copy this file to the destination server.

From a command prompt on the destination server enter the following:

netsh dhcp server import c:\dhcpdb.txt all

While still on the destination server go to Administrative Tools > DHCP.  Right-click on the server object select Authorize.

Wait a few seconds and select refresh, verify the green arrow appears on the server object.

Make sure to de-authorize the DHCP server on the source server.

Go to a command prompt on a desktop and perform a ipconfig /release, ipconfig /renew.  Then type ipconfig /all verify the desktop is pulling it’s ip address from the new DHCP server.
