Rules tuning categories

If you don't have a certain device or application, you should not be running the rules for them. Here are a few that I have gone through. Just add them to your exclude rules list. Feel free to verify these and add other categories for others.

Re: Rules tuning categories

I added some of these to the exclude list, then did a save and apply, but after it finished processing, they were no longer listed.  Is that normal?  I could not find anything in the admin guide on this either.

Thanks.

I noticed that too. Sometimes I had to do it again.

Re: Rules tuning categories

By putting them in one at a time, I got in three rules to the exclude list.  One rule each line.  It won't take a 4th rule however.

Any ideas?  Is there an alternate way to do this?  I do have PuTTY access, but am not at home in this system.

I just copied and pasted them in and that's when I noticed too that sometimes the list wouldn't persist after saving. Obviously a bug in the GUI because I put them in directly like you mentioned and didn't have that problem. The file is /etc/snort/rules/exclude.rules

Re: Rules tuning categories

Thanks, editing it directly worked.  Now they show up in the GUI too, and I did an apply... of course that wiped them all out again.
I put them back in directly and reset the shield.  The file was empty after the Shield rebooted.  So I put them back in, and rebooted, again the file was cleared.

Am I missing something?

/usr/lib/lua/luci/controller/snort.lua and /usr/lib/lua/luci/model/cbi/snort.lua are responsible for how LuCI works with the Services > IPS section.

In the cbi/snort.lua this is the code for exclusion tab:
.....
        --------------------- Exclude Rules Tab ------------------------

        config_file5 = s:taboption("tab_rules", TextValue, "text4", "")
        config_file5.wrap = "off"
        config_file5.rows = 25
        config_file5.rmempty = false

        function config_file5.cfgvalue()
                local uci = require "luci.model.uci".cursor_state()
                file = "/etc/snort/rules/exclude.rules"
                if file then
                        return fs.readfile(file) or ""
                else
                        return ""
                end
        end

        function config_file5.write(self, section, value)
                if value then
                        local uci = require "luci.model.uci".cursor_state()
                        file = "/etc/snort/rules/exclude.rules"
                        fs.writefile(file, value:gsub("\r\n", "\n"))
                        luci.sys.call("/etc/init.d/snort restart")
                end
        end
.....

but the code looks clean and similar to the other codes access when changing the custom rules, threshold config etc.

Re: Rules tuning categories

Just discovered that this script: /etc/snort/rules/exclude_rules.sh parses the exclude.rules contents against the currently loaded snort.rules file and removes entries.  

#!/bin/bash

EXCLUDE_RULES=/etc/snort/rules/exclude.rules
SNORT_RULES=/etc/snort/rules/snort.rules

# Remove all blank lines
sed -i '/^$/d' $EXCLUDE_RULES

# Remove all non-numeric entries
sed -i '/[^0-9]/d' $EXCLUDE_RULES

while read -r line || [[ -n "$line" ]]; do
        sed -i '/sid:'$line'/d' $SNORT_RULES
done < $EXCLUDE_RULES

To make to Webgui accept the list, I just had to remove the hidden trailing spaces after each numbers.
It worked without a problem

Dang, great insight!  That worked for me as well.  Now the entries stick around.

Hi
just modified the scrip so it removes all blank space from list, seem to work ok,

#!/bin/bash

EXCLUDE_RULES=/etc/snort/rules/exclude.rules
SNORT_RULES=/etc/snort/rules/snort.rules

# Remove all blank lines
sed -i '/^$/d' $EXCLUDE_RULES

# Remove all non-numeric entries
sed -i '/[^0-9]/d' $EXCLUDE_RULES

# Remove all blanks so gui accepts list properly (added by roadrunnere42)
sed -r 's/\s//g' $EXCLUDE_RULES

while read -r line || [[ -n "$line" ]]; do
        sed -i '/sid:'$line'/d' $SNORT_RULES
done < $EXCLUDE_RULES




Hans maybe worth putting into hotfixes

Thanks the editor you added is doing what it supposed to do but I just tried it and the GUI still wasn't saving it so there must be a bug somewhere else. Added directly to the file and it saved with no problems.

That fix isn't in the hotfix. Just copy and paste it in and you'll be all set.
