pfSsh.php playback pfanchordrill (when portal is active)

stephenw10

Ah OK interesting. Let me see here....

stephenw10

Yup. Also in 25.11:

Did you open a bug for this yet?

Noop.
I only post a bug report when I know what the reason is.
Afaik, its a pfctl issue, or just the pfctl man pages not telling everything and /etc/phpshellsessions/pfanchordrill is using pfctl the wrong way.
Very view use the command line command "pfanchordrill" I guess.

edit : I looked into it a bit.
When I delete my "Allowed hostname" (see above) - I added an "Allowed IP Address" as this is for me bascilly the same,
and I have now to reboot to remove this :

a this "hostname_0" entry seems to get stuck/invalid, as I removed the "Allowed host name".
Now I get a clean :

which does correspond with the actual portal 'pf' working set :
A (one) IP address - the one I converted from host name to IP.
The 3 actual logged in portal visitors.
The 4 MAC Allowed entries.

So, as "host names" are just entries that will be converted to IP first before being entered into 'pf', is this process that fails.
And is "hostname_0" correct - where does the came from - my portal ID is "2" ?
Why isn't (my case) the anchor called : "cpzoneid_2_hostname" ?

Does the hostname actually work? Can clients access it before logging in?

I would have expected a lot more complaints by now if it didn't.

Yes.
It put in the place the IP of the hos name, and the access was fine : before the portal clients logs in, he can access this IP or host name resource (a guide, PDF, that shows the portal login password - if this wasn't working, they would have to contact the reception - and they don't).

Remove de IP, put back the host name, and it's again :

edit :

$cpzoneprefix = /etc/inc/global.inc line 44 = 'cpzoneid_' + the zone ID becomes 'cpzoneid_0'

/etc/inc/captiveportal.inc, line 2623

An alias entry is created :

$aliasesnames[] = $cpzoneprefix . '_hostname_' . $id;

Example : 'cpzoneid_0_hostname_0'.

The function filter_captiveportal_aliases() is called from /etc/inc/filter.inc, line 1232694

But look at the comments above :

That's not the format return in the array !
It's 'cpzoneid_0_hostname_0'
Not 'cpzoneid_X_allowedhosts/hostname_X'
(neither 'cpzoneid_X_host_Y')

This /etc/inc/filter.inc line 1069 list probably the expected anchor names.

The thing is : after the alias array is parsed, filtered, etc, the remain items are deleted : /etc/inc/filter.inc line 1239.
Wrong stuff, or less worse, non exiting stuff gets deleted here.

Hmm, seems like it could be a pfctl bug:

[25.07.1-RELEASE][admin@6100.stevew.lan]/root: pfctl -sA
  cpzoneid_2_allowedhosts
  ipsec
  natearly
  natrules
  openvpn
  tftp-proxy
  userrules
  cpzoneid_2_allowedhosts
  cpzoneid_2_auth
  cpzoneid_2_passthrumac
[25.07.1-RELEASE][admin@6100.stevew.lan]/root: pfctl -vsA
  cpzoneid_2_allowedhosts
  hostname_0
pfctl: DIOCGETRULESETS: No such file or directory

Gertjan

@stephenw10

yep, as soon as the -v (verbose ?!) option is present, errors pop up.
Seems innocent, but anchordrill uses it.

stephenw10

Yup, we are digging...

marcosm

The error reported by pfctl will require further investigation and is unlikely to be addressed in 25.11. I've updated the pfanchordrill script in 25.11 to work around the issue.

@marcosm

the pacth looks beautifull :
