{Complete} Timebased Rules
-
Hello Scott,
i agree, a little annotation:When you finish the coding behind the gui, please take a look to my requested features…..
Greetings
HeikoDisregarding the bugs in the gui, do you like it so far? Do you find it easy to use? Will it meet your needs?
-
Good Morning,
yes, i think we can finish the discussion about the gui, any bugs can be fixed later. Good Job!
About the Firewall States: My Opinion: –> The expiration of a schedule must kill all the states, it is absolute for me, russia is very strange and i must kill all states from russia to switzerland at the expiration.........
Scott: i know, to kill the states it is a big JOB! But also you a very good coder... :)
Please verify, what do you mean, Scott?

@sai:
Having a really hard time figuring out how we are going to kill old states. Is this an absolute requirement for the bounty or is blocking new connections "good enough"?
Easy way out would be an option to reset all states on the rule. When the rule comes into force, you reset the states if the option is ticked.
Not so easy. So how would you calculate this without redoing pf's logic in php?
I meant use filter_flush_state_table and reset all the states in the state table, not just the states affected by the rule. Not very elegant but I usually Reset States when I change/add a rule.
The other option would be to parse the states to see if they match the rule and only kill the states that match. non-trivial :-)

Hang on here. The person that sponsors the bounty has say so over this feature but with all due respect unless you contributed to the bounty then please sit on the sidelines.
Forgive me, I just tried to help!

Hello,
good news of the weekend??Greetings
Heiko -
Backend is in place except for state killing. Waiting on front end work to be commited.

What is with the state killing? You don't really mean that ;)

heikoState killing is referring to cutting off current connections when a schedule expires. I will be working a lot on the GUI

I now have a solution (mapped out in my brain) on how to do the expiration of states. It will involve using ipfw to insert non stateful deny rules when a rule expires.
We'll see if there are any bugs lurking in FreeBSD here. I am still working my way through dummnynet + pf woes.
-
Fine! Let´s go….
-
Okay, we just put the finishing touches on the time based rule system and my initial tests are positive.
The client gets cutoff correctly at the correct time.
Please test the holy beep outta this and report back.
Snapshots are building. Should be ready about 1-2 hours after this post.
Thanks!

Everyone please take a sledge hammer to these timed based rules. If you find a bug please report as much detail as possible.
We are still determining how we will display the schedules under the firewall_rules.php page. More to come on that soon. But for now, the rules are active when the current time of the firewall matches the specified ranges in the applied schedule(s).
-
Ok, you asked for it! /me pulls out sledgehammer
Issue #1 (text only)
Time minute input error dialog doesn't match the text below the time text boxes in the Time section (Dialog mentions "59" is allowed, webpage text doesn't)Fix: Synchronize text between both places to what is actually correct.
Issue #2 (text only)
Error text (in red at top of page) returned when a Schedule Name has a space in it states:"The schedule name may only consist of the characters a-z, A-Z, 0-9, -, _"
The text below the text input box states: "The name of the alias may only consist of the characters a-z, A-Z and 0-9"
Fix: Synchronize text between both place to what is actually correct. Adding a name with a dash or underscore triggers the error text so I assume those aren't allowed and what is under the text input box is actually the most correct.
Issue #3: Receive errors in log when after associating time schedule to a rule then applying that change. Errors confirmed after trying to add a new time schedule to a rule.
php: : There were error(s) loading the rules: /tmp/qwanRoot.rules:10: syntax error pfctl: Syntax error in config file: pf rules not loaded pfctl: load anchors - The line in question reads [10]: set loginterface xl2 php: : New alert found: There were error(s) loading the rules: /tmp/qwanRoot.rules:10: syntax error pfctl: Syntax error in config file: pf rules not loaded pfctl: load anchors The line in question reads [10]: set loginterface xl2Suggestion: Please add a "no spaces" hint to the "Schedule name" section. Even though a space isn't in the range "a-z, A-Z and 0-9", I'm a little more dense that most techies, so I need some help.
Workflow/Webpage ergonomics: I keep trying to add my info then hit the Save button at the bottom. After puzzling about that I noticed the "Add Time" button to add different time slices to the schedule. My suggestion would be to consider adding a little more text to the error text "The schedule must have at least one time range configured"…possibly "did you Add your time range to the schedule with the "Add Time" button" or something to that effect. Too wordy, I know...but I hope you can see what I'm suggesting..a small hint.

Since I can't get the rules to load with a schedule associated with it, I can't test this so I'll ask it here…
If a client on the LAN is using Squid in either normal or transparent mode, will they be able to surf the internet even if I have a rule in place to block them? (This was an issue in ClarkConnect at one time when using the Squid proxy bypassed firewall block rules)
Now that I re-read this, it isn't really a time-based rule question. But, I'll leave it anyways and you can call me "stupid". :\

#3 fixed now. Thanks!
#1 and #2 are being fixed as I type this.

Good question. You'll have to test and let us know :)

Suggestion: If the rules are limited to only 5 minute ranges allowed (00, 15, 30, 45, & 59), wouldn't a drop box be better then a text input box? This would eliminate input errors. Same for the hour section.
I don't know if that fits into the pfSense "style" or not.

Yes, very good idea. We'll look into it.

After looking at the code in firewall_schedule_edit.php there looks to be a typo on line 581 ("td.innerHTML=" twice @ beginning of the line)
td.innerHTML=td.innerHTML="

I'm full of suggestions tonight…
If you get rid of both the hour and minute text boxes and replaced them with one drop down box you could eliminate both the checkKeyEntry() and checkTimeLimits() Javascript functions. Yes, the drop box would have 97 entries, but I think it would be worth it.
The way that's done in ClarkConnect is to build the < option value ="00:15" >00:15< /option > entries with two loops.
Pseudo code (I haven't coded in PHP since early 2003)
Hour loop - loop from 0 to 23
Minute loop - loop from 0 to 45
If hour= 0 then
Add a zero to the hour in the < option > entry (i.e. "00") $hour . "0:" . $minute
Elseif minute = 0
Add a zero to the minute in the < option > entry (i.e. "00") $hour . ":0" . $minute
Else
Output hour:minute to < option > entry
End if
Return minute loop
Return hour loop
Add < option > for 23:59I hope I'm helping, not hindering when making these suggestions.
