Our systems group is asking if it would be Ok to turn off certain services due to potention security risks. The following are being contemplated.

Service
chargen
daytime
discard
dtspcd
echo
exec
finger
fs
gssd
in.comsat
kcms_server
ktkt_warnd
login
name
rpc.cmsd
rpc.metad
rpc.metamedd
rpc.metamhd
rpc.rusersd
rpc.ttdbserverd
rquotad
sadmind
shell
sprayd
sun-dr
talk
walld

Are there any compelling reasons to "not" turn any of these off?

Note: If I posted this in the wrong forum, I apologize (let me know which and I can repost).

Thanks, in advance, for your help.
