Hi Enrique,
If you are using the cluster feature of the status module to monitor all
the systems from a single webmin server, then the information about
which monitors are up and down is already available on that master
server. It can be found in the file /etc/webmin/status/oldstatus , which
is a text file in which each line is in the format :

id=status

The 'id' is the ID of a monitor, and status is the result from the last
check. 0 = down, 1 = up, other numbers indicate other types of failures.
You can read that file easily in a webmin module with the read_file
funcion, which converts it into a hash.

The actual details of each monitored services are in files in the
/etc/webmin/status/services directory. You can either read those
directory, or make foreign calls from your module to the status module
to read them, with code like :

&foreign_require("status", "status-lib.pl");
$serv = &status::get_service($id):

I'm pretty sure I got the metaphor from you, Craig.  Really, I think 
read it in one of your posts a few days ago and immediately thought, 
"Perfect metaphor!"  ;-)

Hold up...I said the performance difference for the whole system, 
including SpamAssassin and ClamAV, would only be about 5% faster with 
Cyrus, if any.  I didn't say that Cyrus by itself was only 5% faster 
than Dovecot by itself for any particular task (though it might not even 
be as fast...I don't know...I've never seen benchmarks of Dovecot vs. 
Cyrus, though I've seen both compared to all of the "slow" POP and IMAP 
servers).  What I said was that Cyrus can't make SpamAssassin or ClamAV 
take less resources, and in any mail server running those services, they 
are where almost /all/ resources go.  I'm sure that Cyrus is extremely 
fast and wonderful in every possible way and I have no inclination to 
criticize it (though I do readily admit why I wouldn't choose it).  I'm 
just saying that no amount of microtuning of the delivery agent or the 
retrieval server is going to make the real resource hogs disappear. 
Dovecot is blazing fast, and I'm sure Cyrus is too (possibly more 
blazing fast even), but on my mail servers, when I look at CPU/memory 
usage Dovecot isn't even a blip on the radar, while anti-spam and AV are 
at the top of the list.

Nobody is criticizing your religious beliefs, Craig.  Certainly not me. 
  I respect all faiths, from Emacs to Vim and everything in between.  ;-)

Nope.  I just want to toss in another reminder that it just doesn't 
matter.  Procmail is 1% of my CPU usage on my most heavily loaded mail 
server and Dovecot is about the same.  SpamAssassin is 30% and ClamAV is 
probably 10%.  When I look at those numbers I couldn't care less whether 
Procmail is being inefficient because a shell is spawned for every 
message.  Even if Cyrus and Sieve are 5 times faster, I'll still only 
save .8% CPU time over Procmail.  I'm just not gonna sweat over some 
pocket change.  ;-)

I'll concede that lack of caching and good indexing in some POP/IMAP 
servers can lead to sluggish client-side response...but Dovecot is not 
one of those servers.  uw doesn't take much CPU or memory, but is very 
slow on large mailboxes.  Dovecot is very fast and still doesn't take 
much CPU or memory.  And you get to keep standard Maildir or mbox 
spools, so all mail tools will continue to work as they always have.  I 
consider that a win.  The lack of which is why Cyrus is a "drink the 
Kool-aid" kind of product.  You've gotta migrate your whole tool-chain 
in order to use Cyrus.

But it is.  I mentioned that when this came up a few days ago.  Usermin 
supports the following folder types:

- System folders like Inbox, Drafts and Sent Mail that always exist.
- Folders in in the mail directory that can be created or deleted by 
Usermin.
- Other files or directories that can be managed as folders by Usermin.
- POP3 accounts on other servers that can be treated as folders.
- IMAP accounts on other servers.
- Composite folders, which combine two or more other folders into a 
single list.
- Virtual folders, which contain a selection of mail from others.

Note that one of those is IMAP, and thought it doesn't state it 
explicitly, local Maildir folders are also supported.  It doesn't handle 
the .subscriptions file yet, as far as I know, but there's no reason why 
it couldn't.  Seems like it would actually be pretty easy to implement...

I'm sure Cyrus is a very fine package.  I'm not just going to be using 
it, unless I find that Dovecot is inadequate (and I also find that Cyrus 
is adequate for the situation that proved Dovecots downfall).  ;-)

Joe

You're right, my code doesn't handle the 'our' before the $VERSION

This is the amount of disk space that can be used before a warning is

This is the amount of space that cannot be exceeded.

This is the number of files that the user can own before a warning is

This is the number of files owned by the user that cannot be exceeded.

The file limits aren't generally used very much, although they can be
useful on filesystems that have a limit on the number of inodes (and
thus distinct files) that can exist.

RE: [webmin-l] Using User Quotas

[Vernon J. S. <ve...@ve...>]

Here is a link that will help you with that.
http://www.swelltech.com/support/virtual-servers/index.html#quotas


Quotas Setup

Quotas on Linux are tricky, not because they are difficult to setup, but
because they are so poorly documented, and what documentation exists is =
more
often than not incorrect to the point of not working. If you are using a
relatively recent Linux version, the following instructions should work
without difficulty.
Guidelines for Quotas

Virtualmin uses standard system disk quotas to limit user disk usage.
Because of this, all user data must reside on the same disk partition so
that the system can maintain an accurate accounting of disk use. The =
/home
partition is an excellent choice for the user data directory, due to =
UNIX
tradition and user expectations. This is why we moved the mail spool to =
a
directory on the /home partition in the mail server sections, so that =
all
mail will reside on the same partition.
Editing fstab

The first step to enabling quotas is to turn them on in the /etc/fstab
configuration file. You can do this in Webmin by browsing to the =
System:Disk
and Network Filesystems module. Then click on the /home partition link.
Finally, locate the Use Quotas? option and select User and Group from =
the
dropdown list. Save your changes.

You can also make this change manually, by editing the /etc/fstab in =
your
favorite editor, and modifying the /home mount point entry to look =
something
like this:

/dev/hda2      /home           ext3    defaults,usrquota,grpquota 1 1

The important bit of the above example is the addition of the usrquota =
and
grpquota directives. These two items enable both user and group quotas.

After adding quota support to your fstab, you'll need to remount the
filesystem, or reboot the system, to make the changes take effect.

that's a rather extreme metaphor Mr. Jones ;-)

the fact is that mailboxes, seen messages, duplicate message supression
etc. are indeed indexed using db's which make it so darn fast. I have no
test data comparing dovecot performance to cyrus so I let your 5%
performance claim go since I have no way of proving or disproving and I
suspect that your 5% claim was just simply a uswag.

Likewise using cyrus-imapd, sieve scripts are all previously bytecoded
(compiled) for faster performance rather than shell execution of
procmail. Perhaps Joe wants to toss another 5% figure at that too.

While you probably can use UserMin to access maildir stores, you aren't
going to benefit from subscription lists, seen state or imap flags
without an IMAP login and if you had an IMAP login, then cyrus-imapd
would work as well...but an IMAP login isn't part of the feature set of
UserMin.

[Joe C. <jo...@sw...>]

Yes.  Dovecot is not a "drink the Kool-aid" kind of server, the way 
Cyrus is.  You don't have to use an alternate mail spool format, no 
outside databases are used, and nothing complicated goes on in a Dovecot 
environment.

I use Dovecot with Maildir spools on all of my servers, and Usermin 
works very well.

What about dovecot as an IMAP daemon? Does it play well with Usermin?

Seconded - even if you don't run BIND for your DNS service, it's still
an excellent reference on how DNS is supposed to work.

[webmin-l] Need advice

[Enrique T. <enr...@gm...>]

Hi Jamie and the rest of the list:

I need some advice in a module I'm developing, so I think you'll be so
kind to help me.
I have many hosts (more than 200) monitorized with the status module
of webmin. Now, I want to show the status of all the computers in one
master host, showing them in a map, and giving them a color in
function of his actual status, with a new module.
I think this can be done with the module reading a local file than
contents the status of all the hosts that have alarms.
But, what do you think it's the best way to put the status of all the
hosts in one file of the master host?
I'm using the onup and ondown commands, but I think it's not the best way.

Thanks

Re: [webmin-l] installed perl modules and version numbers

[Obantec S. <su...@ob...>]

Hi Jamie

i thought you would.

a module i was checking has
our $VERSION = '0.15';

which i guess blocks your check as it does not expect to see *our* in front
of $VERSION = '0.15';

Re: [webmin-l] installed perl modules and version numbers

I get the version by checking for a special definition in the module's .pm file ($VERSION I think). However, not all Perl modules define it, and it is not mandatory.

Hi Jamie

FC3 dev 1.225 of webmin

while checking for latest versions i came across a minor issue, how do you
get the version number of perl modules installed. a few are not listing
their versions.

or is it not *required* for all modules to reveal their version.

RE: [webmin-l] Understanding daily "LogWatch"?

[Vernon J. S. <ve...@ve...>]

Okay I had to do some updating on my site (FAQ) and on the script to handle
some issues but here it is SSH Brute Force Black List v1.9

Please take note this is not a plug in to Webmin or Virtualmin this is
strictly a Perl script that will help you against brute force attacks under
ssh. You can modify it to work as an FTP Brute Force Black List. If you are
unable to make that modification then I can make a separate mod for that
purpose just post it on the forums and I will get around to it.

You can download it at.

Bear in mind this will not block your attacks, it will only block an
attacker from 
logging into Webmin, it is better to block the IP from your box all
together.

Unfortunately, you didn't exactly do anything wrong - rather you, ran
into a possible mis-feature of webmin that causes config files to be
removed when un-installing. For most modules this doesn't matter much,
but for virtualmin it is annoying because it has quite a lot of it's own
configuration data.

If you have a backup of the /etc/webmin directory, you could just
restore /etc/webmin/virtual-server to get back all your sites. Ideally
the built-in virtualmin backup feature would be able to restore from
this kind of problem, but it cannot at the moment .. although I will
certainly fix that in future.

The easier solution to the problem of a restart failing is to use the
Bootup and Shutdown module to create a new action called 'webmin' that
runs /etc/webmin/start at boot time.

RE: [webmin-l] Understanding daily "LogWatch"?

[<dav...@da...>]

I recently recovered from a server hack.  They got in through a SimpleBlog
hack that a user had uploaded onto their directory [Web hosting obviously].

The Hacker [they were talked to via IM] took over the box and was very...
strange... he kept the box running for about 4 days and then one night 'rm
-fr /' the whole box.  We figure he was waiting for us to offer a dollar
amount to fix... perhaps so we couldn't get him for extortion?  

The box took over 24 hours to recover and wasn't fun.  Personally if I was
"you" I'd make sure the firewall is configured and also consider if you can
not set the "allow connections only from" certain IP's to SSH etc, (due to a
dynamic ip address) set up some MAX connection situation to block
connections when they are getting dictionary hacked.

Now another method is door knocking to open the SSH port, but quiet honest
this appears to be quiet above your current skill level.

BTW: You can "turn off" SSH in Webmin, and only turn it on when you need to.
Personally most people do it the other way around... but hey ;)

I see.

Thanks for that information.

Sorry to ask such a dumb question but:

What can anyone gain by getting into my server by this method?

Is it simply vandalism, or is there some sort of point to it?

For instance, does it allow the "hackers" to use my server to
run their own websites or email/spam programs?
