Multiple argument wildcard matches for sudoers file?
I'm trying to figure out how to create an entry in the sudoer where I allow a limited set of arguments some optional but have the command still very restrictive.
Is there any easy way to limit these restrictions?
I'd like the user to be able to run with the -w flag and optional value but still be restrictive. I don't want to hardcode values for the -w option. The user should be able to run any of these commands with 10 being any digit.
/usr/bin/iptables -nvL *
/usr/bin/iptables -w -nvL *
/usr/bin/iptables -w 10 -nvL *
I came up with these 4 entries. Is there a better way to have optional values defined?
username ALL=(root) NOPASSWD: /usr/bin/iptables -nvL *
username ALL=(root) NOPASSWD: /usr/bin/iptables -w -nvL *
username ALL=(root) NOPASSWD: /usr/bin/iptables -w [[:digit:]] -nvL *
username ALL=(root) NOPASSWD: /usr/bin/iptables -w [[:digit:]][[:digit:]] -nvL *

You can use Cmnd_Alias function.
Cmnd_Alias ITEM_IPTABLES = /usr/bin/iptables (-w)? [[:digit:]]* -nvL *
Then add the Cmnd_Alias you defined to the commands list you want ignore asking password by sudo.
USERNAME ALL=(root) NOPASSWD: ITEM_IPTABLES
From man 5 sudoers:
? Means that the preceding symbol (or group of symbols) isoptional.
That is, it may appear once or not at all.
* Means that the preceding symbol (or group of symbols) may appear
zero or more times.
Parentheses are used to define group of symbols.

Great! That was exactly what I wanted. I should have read the whole man page. I thought sudoers used globing, never heard of EBNF. Thanks.
