Command to check if a service is enabled or disabled ?

Hi,

 

Which command can be used to check if the unused services are disbled or enabled? 

We use Cisco 2811.

 

Thanks.

Can you be more specific?

Which type of services are you talking about? because it depends on the service or what you are looking for...

 

Is a good practice to disable all the services you are not going to use on your router, so lets say for example we submit the following commands:

conf t

no identd

no ip domain-lookup

no ip http server

no ip finger

no service pad

no snmp-serverno

no snmp-server community private

no snmp-server community public

no service tcp-small-servers

no service udp-small-servers

no ip gratuitous-arps

 

Now, instead of check one service at the time you can try with

 

show run  | i no ----------------->(adding a space at the end) and see which service are disable.

Is there an specific command to do that, I dont know it.

show running-config all shows the full config including defaults.
show running-config all | include ^service|^no service will show you all the services that are enabled or disabled.

This being IOS, I wouldn't be absolutely sure that's everything. E.g. [no] service ? in config mode offers alignment, finger, and others that aren't in the show run all.
And it's not actually a list of what's running on the device. For that, I don't think there's anything better than show process and knowing the names of the services to look for.

I couldn't find a good reference for services either (that's how I ended up here), but this bit got me looking in the right places:
