Re: OT : Small home rack

[Stephen]

something to consider with making a home multi-machine network is the small
size and relative performance of Nettops (dual core with Hyper-threading and
a Gforce 9200 with 2gb ram in a form factor of a largish paperback.

alternatively would be to look at the size/shape of printer carts and 2u-3u
cases from Compucase, and essentially convert a regular desk into a desk and
integrated rack. but for most home users unless developers or higher end
geeks this combination is unlikely to catch on. (although media servers in
high end homes can catch on if you want to research Linux MCE).

I have planned and thought about allot of these designs and can give you
some really good bits to look at if you want to go on. but if whatever you
produce does not become a real space saver and look at least
somewhat aesthetically pleasing it is likely to not be very popular. contact
me off list if you want and we can discuss this more.

Thanks to all who responded.  The combination of single-quoting some variables 
and changing my delimiter solved most of the problems I was having, though, 
sadly, not all.

Re: perl or sed s/// problem

[Kevin Brown]

line="passwordrequisite /lib/security/$ISA/pam_cracklib.so
newline="password required /lib/security/$ISA/pam_cracklib.so
I need to maintain whitespace

perl -p -i -e s/"$line"/"$newline"/  file

That tosses out all kinds of errors


Modern regexp engines allow you to use an arbitrary char as the pattern
delimiter.  If I've got slashes in my patterns, I tend to use # as the
delimiter, which allows you to avoid Leaning Toothpick Syndrome.  Other people
may use | .  # is visually distinctive and not as common as / in some
string-replace contexts, though:

perl -p -i -e 's#"$line"#"$newline"#'  file


The | sits right under the \ on the keyboard, so it is easy to put into 
scripts. The # may seem like a reasonable delimiter unless the lines 
being read in have comments in them. In which case most files I've seen 
use the # to denote a comment or a comment line...

Re: Qmail on CentOS

[Eric Shubert]

I just tested this, and it appears that register_globals don't even need 
to be on to change the password. I'm not sure why that's in the 
instructions any more.


Thanks for bringing this up. We're looking into it.

Now that I look a little closer, the instructions say to set
register_globals On only to initially set the admin password. Right
after that it says to turn it back off.

I'm sure that QMT will have a proper fix for this in due time.

Closer to 4 hours probably, depending on how you do it, and your level 
of expertise. There is even an ISO available that loads the whole thing. 
That way is trivial, but there's a nominal fee associated with the 
latest ISO.


I'd be glad to help anyone build a QMT at an installfest. I won't be 
able to make the IF this month though.


I recall reading about the Qmail Toaster maybe 6 years ago maybe 
longer.  And at that time there was a control panel that could be used 
once the install was complete.  Is that still the case.


Yes. All admin functions are not GUI (yet), although managing accounts 
is all web based.

I've been running qmail-toaster for years, and am active in the
community. I know that qmail has its drawbacks, but QMT far
outweighs them. Do check it out.

If anyone's interested, I could do a presentation at a meeting about
QMT. You can build one from scratch in nearly that amount of time
(once you know what to do, of course).

Re: Qmail on CentOS

[keith smith]

So basically once you know what you are doing it is an hour exercise.  the 
first time it is an 8 hour project.

I recall reading about the Qmail Toaster maybe 6 years ago maybe longer.  And 
at that time there was a control panel that could be used once the install was 
complete.  Is that still the case.

I've been running qmail-toaster for years, and am active in the community. I 
know that qmail has its drawbacks, but QMT far outweighs them. Do check it out.

If anyone's interested, I could do a presentation at a meeting about QMT. You 
can build one from scratch in nearly that amount of time (once you know what to 
do, of course).

That wiki page should be updated. I've been running with register_globals off 
since I don't know when. No problem.

Re: OT : Small home rack

[keith smith]

Okay, so lets go another route.  I could make do with two laptops.  I would 
like a little more.  Raid 1 for my Linux Dev Box.  So two desktop boxes would 
work.  Then I could just stack one on the other, add a KVM and I get about the 
same effect.

I have all towers now however that is because that is how they come from Dell.  
When I used to build my own I used to always use desktop cases to maximize the 
room and to lift my monitor up a few more inches.  My monitor could be higher, 
by about 4 inches.

So I also agree with towers instead of racks. My ex-roomate had a 2 u rack 
server and was loud and sounded like a leaf blower. Now if you go with a 1u 
then storage will also be an issue because of the height (and i think 4 drives 
at most). With towers, as brian said, are much quieter and if you get a server 
type case, then you can fit a lot more drives in the machine before resorting 
to external raid device. With that said, i do have a tower myself and am quiet 
content with it with the noise and performance. Another thing to note is that 
it is easier to add add-on cards to the machine such as a raid controller or 
lan card.

Like yourself, I expect that most geeky types would prefer to "roll their own".

Personally, I have 4 VM hosts (1 prod, 3 test/devel) in my closet (literally). 
They're on shelves with the rear facing out. They all run headless most of the 
time, but I have a monitor and kb I can easily attach when there's a problem. 
I've also wired the closet with appropriate power (UPS for prod) and 
networking. Everything's out of sight, very quiet, and relatively low power 
consumption. I also added a vent at the top of the closet to allow whatever 
heat to
 dissipate.

Yes, this is a common solution to this problem.  I've often seen, and
have occasionally used, the control-A character used as a delimiter.
It works fine and control-A is unlikely to occur in text.  The challenge
then becomes finding how to enter control-A into a script with your
favorite text editor.

Qmail on CentOS

[keith smith]

Hi,

I have a backup server that I want to also run as a backup mail server.  It is 
running Qmail.  Running a mail server is all new to me.

What is the best way to get started.  Book, Man Page,...?

Bind, Mail, and Apache to a lesser degree have kept me from running a web 
server from the command line.   I've been able to get by with Apache however I 
know I need to learn a bunch more.

Any help is much appreciated.

Re: OT : Small home rack

[Eric Shubert]

Like yourself, I expect that most geeky types would prefer to "roll 
their own".


Personally, I have 4 VM hosts (1 prod, 3 test/devel) in my closet 
(literally). They're on shelves with the rear facing out. They all run 
headless most of the time, but I have a monitor and kb I can easily 
attach when there's a problem. I've also wired the closet with 
appropriate power (UPS for prod) and networking. Everything's out of 
sight, very quiet, and relatively low power consumption. I also added a 
vent at the top of the closet to allow whatever heat to dissipate.

I think that a tower would suffice in SB/home environments. With
virtual hosts, of course. ;) I'm personally using an old
(retired/reprovisioned) P4 SFF workstation (w/ 5 VM guests) as a server.

I'm thinking tech folks like us.  I sure would find it beneficial.  By building 
your own you can control the price and performance.  It may not be cheaper 
initially however once one does an upgrade the benefits are there.

Racks are an issue of space - most people have the space for a big
tower in there home and would rather have one tower that ran quieter
and had twice the performance specks of the equivalent cost rack
server. I have a 2 U (clients) rack behind me now that I don't run
because of the noise. Instead It is all VM'ed and I copied the VM's to

.) you should probably have quotes around the -e argument, as in:
perl -p -i -e "s/$line/$newline/" file

.) I'm not positive, but I believe that the character immediately after 
the s becomes the separator, so you could use s|from|to| or s^from^to^ 
or whatever. Otherwise, simply use \ before the special character to 
escape it from being interpreted as being special (iow, treat it literally).

Try something like

$ sed -e "s|$line|$newline|" file

You probably also want to define your variables like line='password ...'
so that the shell preserves the literal value of $.

Modern regexp engines allow you to use an arbitrary char as the pattern
delimiter.  If I've got slashes in my patterns, I tend to use # as the
delimiter, which allows you to avoid Leaning Toothpick Syndrome.  Other people
may use | .  # is visually distinctive and not as common as / in some
string-replace contexts, though:

perl -p -i -e 's#"$line"#"$newline"#'  file

I was wondering if there would be a need or market for a small simple rack for

servers.  I'm thinking it would stand about 3 ft.  I would think there would be 
a need for wheels on the bottom or a way to swivel the servers to get to the

You might try your city's parks and recreation center.
