I used to work at a place that only allowed port 80 connections and did 
(I can't recall as that was several years ago) need to be "Tricked" into 
port forwarding ssh to port 80 on the local workstation. I used putty to 
do this but for the life of me I can't remember how I did it. I'll ask 
another ex-employee if he remembers. It sucks getting old! 8*))But you 
said you can or can not ssh into your box from work? Maybe Jamie knows 
how to fool those silly proxy work sites.

i used the easiest option, at the bottom, without a virtual host.

Re: [webmin-l] Webmin telnet/ssh application and starting/stopping daemons

[<fl...@ma...>]

Doc,

One thing I did change, was that I'm coming into Webmin using a mod-proxy
arrangement.  I cannot use regular ports, only port 80 at work, so I
proxied the  x.x.com/webmin directory through localhost:10000, and the
reverse as well.  Does this preclude me from using the app?

I *NEED* to SSH to my box, but the firewall here only allows inbound and
outbound  traffic on port 80.

Is there perhaps a different solution I should look into?

Re: [webmin-l] Webmin telnet/ssh application and starting/stopping daemons

[<fl...@ma...>]

Doc,

Yah, its running, and SHOULD be configured to allow my ID access.  As I
say, I can access it through the regular port from Putty or SecureCrt.  A
buddy of mine can too, from Fl. .  I'm coming at it from the internet. 
And on my laptop, connected via regular DSL (wireless local connection), I
have no problem.

You do know for certain SSH is running and configured correctly on the 
boxen? Sounds like it either isn't running or could be something like 
your hosts.deny is set to deny ssh to any connection.

Is this server on a local network? Or are you trying to come in through 
the Internet?

I'd check those and let us know what you find.

Ok,

Shutting down firefox allowed me to "see" the login script.  Now I get : 
Sorry, could not connect. Java.net  connectexception: connection timed
out: connect

Yet if I connect using SecureCrt, it works.  I appologize in advance for
being such a nnoob at this, but I'm not all that SSHish.

[webmin-l] Shorewall module feature change

[Ivica G. <ivi...@la...>]

Hi Jamie

Searching trough mail list i've found out that you maintain Shorewall =
Webmin module as core module, so here is my question:

Is it possible in Shorewall Firewall Rules screen to have Source and =
Destination hosts (IP addresses) separated with space when displayed? If =
you put for example 40 IP addresses in either one of those fields, table =
becomes so wide that it's hardly readable even on extremely high screen =
resolutions as IP addresses make table very wide. If they would be =
separated with space, browser would automatically wrap contents of those =
columns and it would become readable so we wouldn't have to scroll right =
to see rest of the firewall rule.

I took another look at the code for this module, and it seems that even
though Webmin just calls the Net::LDAP module's search function, this
takes a long time to respond on large LDAP databases even though no
actual results are requested!

However, I managed to find another way to reduce the search size, by
specifying a maximum result size to the LDAP server. This will go into
the next (1.330) Webmin release.

If it does things in the sequential manner then I am not sure why it is
so slow for me.  There is nothing wrong with the performance of the ldap
server.  I can do an ldapsearch from a client machine and dump the whole
list of users into a text file in less than a second.  Going into the
first ldap users and groups screen with the list of users takes > 10
secs even with the amount of users to display set to 0. I am not sure

This can indeed be done, typically be setting up an Apache virtual host
to proxy port 80 to port 10000. See http://www.webmin.com/apache.html for
the details - just make sure you read the section on using ProxyPass.

[webmin-l] webmin access through port 80?

[<fl...@ma...>]

Hello,

I am at a contract with a client that only allows traffic inbound and
outbound through their firewall for port 80.  I cannot access my webmin at
URL:10000 like I usually can.

Is there a way to configure webmin to respond to requests on port 80, but
use a different directory?  Say : http://www.mydomain.com/webmin  ????

I cannot SSH into the machine either, or I would simply do my admin via
SSH.  Maybe there is an SSH client/server solution that uses a webserver?

My needs are a bit urgent, so any assistance is appreciated.

Actually, that is what the module already does. The main page does an
LDAP search for matching users, and then checks the number of results available.
If this is higher than the maximum set on the Module Config page, it just
displays the search form without fetching the full user list.

Of course, for this to be useful I assume that the LDAP server doesn't
fetch users from it's database until actually asked to..

[webmin-l] LDAP Users and Groups module performance

[Murray T. <mtr...@ce...>]

Hi Jamie

We now have over 1000 users we manage with the LDAP Users module.  I
have noticed lately that it is becoming very slow bringing up the
initial screen.  I can imagine things only getting worse as the
directory gets larger.  I haven't checked the queries My guess is that
the module tries to search the LDAP directory for the whole list of
users, then after realising there are too many, it then says there are
too many to display and fails.  Even if I set the maximum number of
users or groups to display to 0 or 1 it still takes a fair few seconds
to display the opening screen.  

The recommed method is to process each LDAP user entry one at a time as
they are returned. The module would stop when it reached the limit of
users for that page which could be a configuration value.  The module
appears to be using the NET::LDAP library.  I had a look at the
documentation below and they recommend processing each entry as it is
returned:  

http://search.cpan.org/~gbarr/perl-ldap-0.33/lib/Net/LDAP/FAQ.pod#USING_THE_CALLBACK_SUBROUTINE_APPROACH

If we want 100 users to be displayed on the page we print the first 100
entries then quit.  If we want users 100-200 we would ignore the first
hundred entries and print the second hundred, and so on.

Hope the above idea has merit and its possible for you to implement at
some stage.

Thanks
