Hi John,

Yes, I tried suggestion 2 but that didn't work.  I used the webmin rpm to
upgrade.

Thanks

Re: [webmin-l] Fetchmail Module - No Mailservers Have Been Specified

Yes; I've logged in as a test user I've created as well as myself. The

I would try suggestion 2 from Jamie. Manually configure the OS and 
release within Webmin. Mine is set to CentOS Linux 4.2.

Also, don't forget to check your ACL list. Maybe it's still there but 
somehow was set to unavailable.

Did you use the Webmin RPM or the Dag RPM? I use the Dag repository but 
have Webmin set as an exclude. There are serious conflicts between the 
two versions. Dag says his is the best, Jamie says his is the best. More 
than likely they are both right from their point of view on things. I 
decided to use the Webmin version as it left all the update functions 
available from within Webmin, not an option with the dag version. I had 
a BIG mess going on several machines for a long time due to this issue. 
At the top of the list was ACLs changing after any update, even for root.

Good luck.

Hello John,

It was previously there when I was at 4.1 after upgraging from WBEL 4.  Not
sure when it disappeared.  Probably on the latest upgrade of webmin.  Any
ideas on how to fix it?

Hmmm.... On a CentOS 4 (upgraded to 4.1), upgrade to 4.2, the OS is 
listed as 4.0 in webmin. On a fresh install of CentOS 4.2, it shows up 
as CentOS 4.2 in both redhat-release and webmin. Webmin put the Network 
Configuration module on both systems. But, maybe the fly in the soup 
here is trying to re-install a module that was removed? Looking for 
centos-release on a CentOS 3.5 install, I see the same thing... 
/etc/redhat-release and no /etc/centos-release. That would be the oldest 
I can check. I do recall the Whitebox replaced the redhat-release with 
wbel or whitebox-release. All of this I'm sure due to redhat trademark 
fears. It wouldn't surprise me if centos-release reappeared as so much 
else has been renamed that way, like all the redhat server management 
programs. Would it create various program confusion to have both 
redhat-release and centos-release in /etc? I bet so.

I'm not complaining here.. only providing information.

Re: [webmin-l] Network Configuration Module

[Jamie C. <jca...@we...>]

This happens because Webmin doesn't detect CentOS 4.2 properly, due to the
removal of the /etc/centos-release file that existed on older versions. The best
fix would be to copy /etc/redhat-release to /etc/centos-release , and remove and
re-install Webmin. However, re-installing like that will cause all webmin and virtualmin
settings to be lost, so don't do it if you have any that you want to preserve!

Alternatively, you can just go to the Webmin Configuration module, click on the Operating
System icon and change the OS manually to CentOS 4.2.

[webmin-l] Network Configuration Module

[Thomas E D. <ed...@al...>]

Jamie,

I noticed my network configuration module was missing.  I deleted a few
unused modules a couple of weeks ago and thought I might have inadvertently
deleted it as well.  So I went to the webmin site and downloaded it but was
unable to install it because my OS was not supported??????

I'm running CentOS 4.2 based on RHEL 4.  Whaaaaaaaaaaaaaaaasup?

[webmin-l] Webmin 1.240 released

[Jamie C. <jca...@we...>]

Hi everyone,

Webmin version 1.240 is now available for download from
http://www.webmin.com/ and mirror sites. This release includes
the following changes :

 * Added a module for configuring the popular Dovecot IMAP/POP3
   server.
 * Enhanced the Custom Commands module to support running commands
   on multiple Webmin servers at once.
 * Added a CSV import feature to the PostgreSQL module, and enhanced
   the CSV export feature to allow selection of columns to include.
 * The Sendmail, Postfix and Qmail modules now all prompt for
   confirmation before deleting messages from the mail queue.
 * The idle automatic logout time can be configured on a per-user
   basis in the Webmin Users and Usermin Configuration modules.

Also available is Usermin 1.170, which has only the following changes :

 * Comments can be entered for jobs in the Scheduled Cron Jobs module.
 * The Mail Forwarding module remembers the autoreply message even
   when it is disabled.

As always, please send me any bug reports or feature suggestions that
you might have.

 - Jamie

I'll add a few minor bits of info to this thread:

P4 processors over 3.0 GHz, P4-based Xeon processors (and not the older 
PIII-based Xeons), and a few other Intel processors have a feature 
called hyper-threading.  This is treated by Linux as an additional 
processor and so if you have one of those processors, Linux will treat 
it as a dual processor SMP machine if you boot into an SMP kernel.  This 
isn't a bug, it's a feature, and increases performance by a small amount 
for some types of task (primarily tasks that require multiple 
simultaneous processes rather than a very demanding single process 
task--a server with a database-backed website would see an improvement 
while a Squid caching proxy server would lose performance).  That's not 
to say there aren't some systems that might get misdetected as multi-CPU 
when they don't have hyperthreading or additional physical CPUs, but I'm 
not aware of any that do.  It would be a bug for a non-hyperthread 
cabable single-core single-CPU system to be detected as SMP-capable. 
Intel has an overview of hyper-threading, including a specific list of 
processors that have this feature, here: 
http://www.intel.com/technology/hyperthread/

An SMP kernel should operate on a single CPU machine without disatrous 
consequences.  Performance will likely suffer, as there is additional 
overhead in an SMP system due to the additional locking required to have 
more than one CPU share a single pool of memory.  If you find 
instability when running an SMP kernel on a single CPU system (that is 
stable when run under a uniprocessor kernel), a bug report to that 
effect to your operating system vendor would be appropriate.  But, there 
is also no reason to run an SMP kernel on a machine that does not have 
either multiple CPUs or hyper-threading.  It does not improve 
performance (it does the opposite due to the extra locks), and increases 
memory usage by a small amount.

Finally, kernels are way outside of the scope of the Webmin list (as 
clearly evidenced by the well-meaning but misleading and/or incomplete 
replies to this query to date).  The newbie or general technical 
discussion list of your Linux distribution would be the place to start 
with a problem like this, possibly escalating to a bug report to your OS 
vendor.

Re: [webmin-l] Fetchmail Module - No Mailservers Have Been Specified

[Jamie C. <jca...@we...>]

I would say that the fact that the cron job is run as root is the cause
of the problem .. however, on my system it is always created as the correct user.
I presume that you logged into Usermin as some non-root user, went to the Fetchmail
module and enabled scheduled checking? If you login as root, it will set up a Cron
job that one check root's Fetchmail config.

wouldn't it be easier just to create the machine accounts on the fly?

add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null %u

[webmin-l] Fetchmail Module - No Mailservers Have Been Specified

[Jason S. <jas...@gm...>]

Usermin 1.170 (with Fetchmail updates applied)
Webmin 1.240
Mac OS X Server 10.3.9

Progress is being made. Now fetchmail is actually started
periodically, but returns the error "no mailservers have been
specified" and I think I know why.

Usermin appropriately creates the .fetchmailrc file in my test user's
home directory. When configuring scheduled checking via Usermin,
though, the cron job is created so that ~/.usermin/fetchmail/check.pl
is run by root, and not by the individual user.

The root user doesn't have a .fetchmailrc file so fetchmail spits the
error and bails.

I manually ran ~/.usermin/fetchmail/check.pl as the test user and it
worked correctly. So the solution seems to be installing the cron jobs
as the user that's running fetchmail and not root. Yes? No?

[webmin-l] Mail Queue Module Wish

[John H. <web...@ew...>]

It would be fantastic, if possible, to have the ability to sort the mail 
queue list by to address, from address, and maybe even status. This 
would be a huge help in finding new spammers. If to and from were sorted 
by greatest sender first.. finding the biggest spammer would be easy.

Best,
John Hinton

It appears that somehow, a significant number of the "wrapper" scripts
weren't actually restored when I "recovered" the Webmin configuration...

I definitely have the Pro version on my list of things to evaluate.

Thank you. Have obtained the update. No output, though. The scheduled
checking page is configured to set to send an email after running but no
email is sent. (The option of only sending when an error occurs is set to
"no".) I'm not sure if it's really checking or if it's just that the email
isn't being sent or what.

Subject: [webmin-l] no more recursive clients: quota reached

I posted this question a few days ago and got no response. Does not one know
what it 
means?


I keep getting the following message from Bind and am wondering if anyone
knows 
anything about this:
 
    no more recursive clients: quota reached 
 
I'm running a Fedora Core 3 box with BIND version 9.2.5 and I have read that
version 9 
has limited queries and you need to modify Bind by adding the following:
 
   options {
         recursive-clients 5000;
   };
 
I assume this goes in the /etc/named.conf file, but I am still getting the
message. I 
even uped the value to 21000 and am still having the problem. Anyone?
 
Thanks
 
Vern

It appears that somehow, a significant number of the "wrapper" scripts
weren't actually restored when I "recovered" the Webmin configuration...

I definitely have the Pro version on my list of things to evaluate.

from man yum

      --exclude=package
              Exclude a specific package by name or glob from updates on 
all repositories.
              Configuration Option: exclude

I would think that in /etc/yum.conf an entry on a separate line such as

exclude=kernel

would do the trick.

Re: [webmin-l] Urgent Help Needed - Kernel Issues

I had a similar issue the past week or so where my system suddenly;y was 
hanging. First I thought is was overheating due to heavy load. But 
careful observation told me that wasn't it.

This chi a FC4 system btw.

Eventually I concluded that yum had updated the kernel RPMs when I did 
full updates. There were 4 kernels on my system under /boot. As I wasn't 
really sure when it started getting flaky (I suspect the last 2, but the 
2nd one I am not sure of) I edited my grub.conf file to force the 
original kernel to boot. All seems OK the last 4 days or so, including 
under heavy CPU load, where before it might stay up an hour to a day or so,

I never suspected a SMP problem - sheesh, is that another thing to worry 
about? kernel updates always make me nervous anyway....is there a way to 
tell yum to not update the kernel unless specifically told to?

Best,

Barry

OK, from RedHat

    3.20.4. SMP Motherboards, GRUB, and LILO

This section is specific to SMP motherboards only. SMP, short for=20
Symmetric Multiprocessing, is a computer architecture providing fast=20
performance by making multiple CPUs available to complete individual=20
processes simultaneously (multiprocessing).

If the installation program detects an SMP motherboard on your system,=20
it will automatically create two boot loader entries.

Note 	*Note*
  =09

Intel=AE Pentium=AE 4 systems with hyperthreading will have an SMP kernel=
=20
installed by default.

The two GRUB entries will be Red Hat Linux (/kernel version/) and Red=20
Hat Linux (/kernel version/-smp). The Red Hat Linux (/kernel=20
version/-smp) will boot by default. However, if you have trouble with=20
the SMP kernel, you can elect to boot the Red Hat Linux (/kernel=20
version/) entry instead. You will retain all the functionality as=20
before, but you will only be operating with a single processor.

The two LILO entries will be linux and linux-up. The linux entry will=20
boot by default. However, if you have trouble with the SMP kernel, you=20
can elect to boot the linux-up entry instead. You will retain all the=20
functionality as before, but you will only be operating with a single=20
processor.

------------------------

So, as I read this, and maybe it might work (or at least the machine=20
might start) on other systems, but all I see is "Pentium 4 with=20
hyperthreading" as an exception. The original poster didn't say a word=20
about what his hardware situation was. I was trying to read minds and=20
didn't know about this processor's special properties.

All I have known before today, was just like this from wikipedia.org

-------------------
*Symmetric Multiprocessing*, or *SMP*, is a multiprocessor=20
<http://en.wikipedia.org/wiki/Multiprocessor> computer architecture=20
where two or more identical processors are connected to a single shared=20
main memory <http://en.wikipedia.org/wiki/Main_memory>. Most common=20
multiprocessor systems today use an SMP architecture.

RE: [webmin-l] Urgent Help Needed - Kernel Issues

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

Here is the thing that I have learned years ago when working with smp verses
a standard kernel. When you get the new kernels you need to select the smp
first after the reboot. When you get the new kernels they comply everthing
needed as if it was a fresh boot. If you switch from a single to a multi
then you are going to have errors and it will not boot. If you go from a
multi to a single you are going to get it to boot but some programs will not
work. Somewhat of a catch 22 if you know what I mean. But any less you can
run a single cpu system with a smp kernel as long as when you first get the
kernel version that that it is a new version than the current one you are
using.

Same kernel version swapping is going to have problems on a single cpu
system unless you specify the new kernel first being a smp.

If this doesn't make sense let me know, but under the RHCE/RHCT it can be
done. There are just rules (instructions) on how to make it work.

You can still use smp under a single processor. At times it can help manage
the load of the server.

Ahh.. OK.. so Fedora 'thought' it found a second processor which you do 
not have. Seems this is happening on several particular systems lately. 
The smp of course stands for multi-processor. Set grub (or lilo if 
you're using that)  to boot from the

Fedora Core (2.6.12-1.1378_FC3)

kernel. Then, under software packages, search for kernel and remove any
kernels with the smp. I don't know exactly why this is happening. File a bug
report on the Fedora site.

Things are getting more complicated in the Linux world. Seems there is a
move to support just about everything that comes along and that's not an
easy undertaking. At the same time, older hardware 'work-arounds' seem to be
getting dumped from things like Anaconda. I think we've been from the almost
nothing is supported era of the early 90s, to the almost anything works era
of the 00s and are moving into the time when moving forward is also moving
backwards with regards to hardware. The pendulum swings!

Re: [webmin-l] Urgent Help Needed - Kernel Issues

[Alan D. <We...@Om...>]

The Red Hat document doesn't state anything about running an SMP kernel
on a single processor system, and I'm not sure what you mean about it
helping manage the load of the server, unless you are referring to
hyperthreading, which is a different issue.

However, Google turned up a pertinent message from the Linux kernel list
back in 1999:

http://www.ussg.iu.edu/hypermail/linux/kernel/9911.3/0283.html

BTW, "UP" refers to "uni-processor" (the opposite of multi-processor),
in other words a computer with only one processor, or a kernel that does
not support SMP.

Here's another interesting thread from the FreeBSD list, which also
refers to Linux and Windows:

...no 'reference' but (by accident ;-) ) by lazyness, here is definitely
a single-processor system running with an (SuSE) SMP-Kernel 8-) ?-)

NOT that I would say that there are any (kind of) performance-/load-
issues --> it's just running....
