Re: Windows GUI diff software with masking capability?

[Vuong Phung <vphung () SCIENCE SJSU EDU>]

Not exactly GUI but will do the job, for such comparison I usually use sdiff with the -s option. sdiff comes with this 
free download from M$ http://technet.microsoft.com/en-us/interopmigration/bb380242.aspx
 
sdiff -s from this download will show only the differences side by side.
 
This is a free invaluable UNIX-utilities package that I recommend every sysadmin to use beside sysinternal tools.
 
Hope this helps. Vuong

Subject: [SECURITY] Windows GUI diff software with masking capability?



I've done some googling, and so far I haven't found what I'm looking for.  We have created a standard router template 
for all of our remote campus routers.  What I'd like to be able to do is compare the router template with the config 
from a router.  The issue is that there are going to be a number of items such IP addresses, hostnames, etc. that will 
be different between the two configuration files.  What I would like is the ability to "mask out" these differences in 
the router template, so differences in configuration will more easily stand out.  Does such a program exist?

 

 

For example:


Remote router:

 

Router Template:


version 12.3

no service pad

 -----------------                            

service tcp-keepalives-ou

service timestamps debug datetime msec show-timezone

service timestamps log datetime msec show-timezone

service password-encryption

......

no ip dhcp use 

ip dhcp excluded-address 10.159.1.100 10.159.1.254

ip dhcp excluded-address 10.159.65.200 10.159.65.254

 

version 12.4

no service pad

service tcp-keepalives-in

service tcp-keepalives-out

service timestamps debug datetime msec show-timezone

service timestamps log datetime msec show-timezone

service password-encryption

...

no ip dhcp use vrf connected

ip dhcp excluded-address xx.xxx.x.xxx xx.xxx.x.xxx

ip dhcp excluded-address xx.xxx.xx.xxx xx.xxx.xx.xxx

 

 

Thanks.
