I knew it was somewhere else, but couldn't find it until now.

Who needs it? I certainly DO NOT! especially if it is FORCED on me,

OK, Lets look at this slightly differently
Any child that is determined enough to view porn, Internet Censorship or 
not, WILL GET PORN!
They may use encrypted bittorrent, or another method, but its not hard to 
get around content filters like these.

Internet Censorship should START and END in the home, and the best thing 
the government can do to help this is EDUCATE the population on the best 
methods to do this.
My favorite two are:
1. Place the computer in a public spot, like the living room, or dining 
room, so the children fear getting caught.
2. Regardless of if you do or not, let you children know that you log all 
website connections, but trust them enough to not have to look at those 
logs.

Social problems (and this is a social problem) CANNOT EVER be solved 
simply with technology. It requires a mix of Education, Technology and 
persiverance.

[SLUG] Flash displays over everything else in webpages on Linux FF

[Scott Ragen]

Hi All,
I'm a little frustrated by web pages that display flash, and their popup 
menus that become hidden behind it.
I know I could block flash, but I don't always want to do this.
I have searched the web and the only solutions I have found are targeted 
for the web admins, and not the client browsers.
Does anyone know any solution to this problem? (and no, emailing the web 
admin is not a solution. Neither is blocking flash).

Thanks,

Scott

One could argue that either server is incorrectly configured. I suspect 
the receiving email server is checking if the sending email is valid in an 
attempt to stop spam.
You could just alias apache@ to your (or another valid) email address, and 
that should stop the problem.

Another good approach to this is make sure your PREFIX is set to 
/usr/local/ (usually the default) when compiling any programs. This will 
keep all custom compiled packages in the /usr/local/ filesystem, and not 
mish-mashed with the distribution specific files.

You have installed Perl Module Compress::Raw::Zlib, you need 
Compress::Zlib.
The RPM package name should start with perl-Compress-Zlib.
I have found it on rpmfind.net here:

I have to disagree. Whilst it may be fast, its not 100% correct.
Most of the time it would probably work, but if there are any blank lines, 
it outputs the current count, and starts again.

Consider the following file contents:
--file contents--
this,is,the,first,line
this,is,the,second

the,above,was,a,blank,line

and,another,blank,line
--end file contents--

On Jeff's original command:
sed 's#[^,]*##g' input.txt | tr -d '\n' | wc -m
15

The perl command:
perl -00 -ne 'print tr/,//' input.txt
753

I'm not skilled enough with perl to correct this, but
If the numbers could easily be added together it would work...

[SLUG] bash script argument passing

[Scott Ragen]

Hi All,
I've got a script that does a few checks, under certain conditions, passes 
the arguments it to awk.
The particular line is simply:
#!/bin/bash
awk "$@"

The few tests I've done work ok, but can anyone see any possible issues, 
with escaping, expansion, etc where it wouldn't behave identical to using 
awk directly?

Thanks,

Scott

Hi Heracles,

Have a look at /var/log/dmesg, any clues in there?
What brand Network card is it? (perhaps posting the lspci -v for the nic

[SLUG] xset force monitor to remain off

[Scott Ragen]

Hey All,
I use synergy at home with my Linux desktop plugged into my monitor via 
dvi, and my laptop via vga. I have configured synergy to do an xset dpms 
force off when I tell it to switch to the laptop, which causes the monitor 
to switch to using the vga port and beings up the laptop- that works well.

The problem I am having is when my laptop also goes into powersaving after 
being in idle for 15 mins, I come back and move my mouse/keyboard - even 
though synergy is sending it to the laptop, my linux box also wakes up, 
and gets the monitors attention first.

My question is, is there a way to "xset dpms force off" (turn monitor off, 
not dpms!) and not wake up on keyboard and mouse events, or wait a few 
seconds before waking? (so the vga connection has a better chance of 
getting the monitors attention first).

TIA,

Scott

Since I don't have a better answer, I should probably keep quiet, but 
there is a flaw in your regex:

my $var = 'a';
if ($var =~ /[EMAIL PROTECTED]|[A-Za-z0-9]+|[EMAIL PROTECTED]/) {

True

$var doesn't match the required 2 out of 3 characters, but still matches.

It could be chomp is removing the newline, but not carriage return(?).
Try instead of chomp this:
$recv =~ s/\r\n//;
or it may be ordered the other way, I can't remember:
$recv =~ s/\n\r//;

Hi Shane,
Can you be a little more specific?
When you chomp, do you get the "Doesn't work" return with nothing from 
$recv variable?
When you don't chomp, do you also get "Doesn't work" returning the string 
from $recv variable?

What I'm asking, is does the hash list also contain a new line, so when 
you chomp, it no longer matches?

There is cygwin, with its Xwin Packages.
Look at http://x.cygwin.com

Another option, especially if its over the net and you don't mind 
installing some server sided software is to use NX.
You can download the free (as in speech) freenx on the server from 
http://freenx.berlios.de/
The free (as in beer) client is downloadable from http://www.nomachine.com

I should've done more investigations; openssh doesn't allow the cipher 
"none" (anymore), the proprietary ssh has the option.
There are patches to enable cipher none in openssh if its really needed.

[SLUG] ADSL Migration from layer 3 to layer 2 with subnet

[Scott Ragen]

Hey Guys,
Internode will be shortly migrating our adsl from layer 3 to layer 2 
pppoe.
I've done pppoe before, so thats not a problem, but we have a 5 ip subnet. 
I'm curious to how I configure the server. (Internode have said we get a 
new ip address for pppoe, but keep the subnet assigned, and will be 
framed-relay through)
As far as I know, I could modify the adsl modem to pppoe, and bridge it 
for the other servers, but I'd prefer the linux server to handle the 
pppoe.

We have 2 machines, and an adsl modem connected to a DMZ, both assigned 
IP's the internode gave us (except the modem of course).
On the main server, is it possible to keep eth0 as its existing ip, and 
configure pppoe through eth0 as well? If so, how do I configure the 
routing on the server? also, what do I need to get it to do to get the 
second server to work? (I assume we don't need to modify the second 
server, but do I need to setup some routing or proxyarp on the main 
server?)

I've googled, but can't find any useful information.

TIA,

Scott

[SLUG] Best place to get assistance with a kernel bug (kernel: unregister_netdevice: waiting for ppp0 to become free. Usage count = 1)

[Scott Ragen]

Hey Guys,
I'm just after a little advice on where the best place to get 
assistance/report a kernel bug, whats the best information to include, and 
any other etiquette to make it as easy for the developers to solve as 
possible.

The issue is we have a multihomed debian server, which I have upgraded to 
kernel 2.6.22.2 in an attempt to solve this problem (I don't think the 
latest kernels 2.6.22.3 and up have fixed the problem after going over the 
changelogs)

Our network setup is as follows:
eth0 - LAN
eth1 - Layer 3 ADSL (This is always on)
eth2 - link for Layer 3 ADSL
ppp0 - Layer 2 ADSL (this tends to go down a few times a day - but comes 
back up on next retry)
tun0 - l2tpns for Windows Roadwarriors.

We have ipsec with multiple peer to peer and roadwarrior setups using 
openswan 2.4.7 with the kernel's ipsec modules (not KLIPS).
I use shorewall for iptables, and traffic control (tc) although I don't do 
any rate limiting, just use tc for routing.
All ipsec communications are routed out eth1 using tc rules.
I have also removed all ipv6 modules from the kernel to make sure that is 
not the cause, with no success.

I can replicate the crash by:
1. bringing up the ppp0 interface.
2. restarting ipsec.
3. having one of our peers make a connection with us. (haven't tried with 
a Roadwarrior yet)
4, bring down ppp0 interface.

This gives the kernel error: kernel: unregister_netdevice: waiting for 
ppp0 to become free. Usage count = 1
It eventually crashes the server, but freezes pppd, ifconfig and ip 
commands with a stat of D (ps describes this as "Uninterruptible sleep").

I can stop the lock, hence freeing up all the commands, including pppd by 
running:
# killall _plutorun _plutoload pluto _pluto_adns

The only the pluto process isn't killed, but then running:
# killall _updown

Corrects the issue.

Any advice or assistance would be welcome.

TIA,

Scott

Try using "-c none". Its undocumented, and may not exist for you, but

I agree that moving the port is security through obscurity, but obscurity 
can compliment good security practises.

For example, a private (login) webpage that doesn't have any referring 
links and the url is obscure, is inherently more secure then the (login) 
being linked from the homepage.

With that said, you would be foolish to ONLY deploy security through 
obscurity.

This is getting a bit further then I've ventured, but afaik, you should be 
able to remove the centrino module and any dependand modules, (mine is 
labelled speedstep_centrino) and inserting the acpi-cpufreq module.

Which driver are you using for the cpufreq?
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

If your using the generic acpi, try the driver specific for your 
cpu/chipset. If not, try using acpi-cpufreq.

Thanks for the response Heracles but its not really an issue for me as I 
was just experimenting with it on a Xeon processor.
I just assumed since its a server processor its not designed for 
powersaving features and put it down to a hardware incompatibility. I 
didn't play audio, but I noticed the user interface was very lagged while 
loading apps and such. I also noticed that under heavy cpu load it didn't 
increase the frequency!
I was just suggesting it to James as a possible issue.

This might be way off, but I had intermittant freezing problems with the

To see what govenor is used, try
# cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Try setting it to performance if its anything but.

Hi Dave,
My guess is you are setting the permissions to 666 on both the directory

Execute is required to recurse into directories.

Sorry, I should have been more clear.
The three SCSI drives are in a raid 5 and raid 1 for the /boot.

The USB drive is a 250GB drive thats sole purpose is for samba sharing 
that doesn't require backups (for example, freely distributable programs 
from the net)

My concern isn't about removal and insertion of the disk on the running 
OS, its that sometimes it may be present on bootup, and other times it may 
not. So therefore the SCSI drives will be assigned different letters if 
the usb drive is not present, which would degrade the array, as they would 
now be sda, b and c, and not sdb, c and d.

On looking at your udev rules, could I apply this to both udev on the OS, 
and udev on initrd, and instead of the USB drive being assigned /dev/sda, 
it will be assigned /dev/usbdisk, and the other SCSI disks would be 
assigned /dev/sda, b and c?

Thanks again.

[SLUG] Debian Sid & USB/SCSI Drive

[Scott Ragen]

Hi Guys,
I recently upgraded our server to Sid & the latest .deb kernel, and I have 
a problem that I'm not sure of the best way to tackle.
We have 3 scsi disks in a software raid, and an external usb drive. Since 
the upgrade of the kernel, the USB drive has become sda, with the scsi 
drives being sdb,c and d.
Its less then ideal to use sda as a usb drive for obvious reasons, and I 
am wondering what is the best way to fix this?

Thanks,

Scott

Hi Bill,
Can you check in /etc/modprobe.d/aliases and see if your old cards module 
is aliased to eth0, and your new cards module is alised to eth1?
If so, just change eth1 to eth0, and remove the other module from the 
alias.
afterwards, run update-modules.

*Note, that I am assuming the modules aliases is setup like debian, if 
not, consult your manual.

They are not always real bounces, spammers are sending spam masking it as

Besides, the rejections I am talking about are no different to the

That is unlikely, as spam programs will not bother creating a bounce 
message for the originating sender, it would just be a waste of its time.

eg:
A spam host connects to my server, attempts to send an email, my server 
rejects it. Since spam hosts are usually designed for maximum output, it 
then simply ignores it. No bounce.
A user sends an email, my server rejects it incorrectly identify it as 
spam. The sending mta sends an email back to the user saying it was 
rejected.

Wheres the spam bounce?

Not bounced, rejected. This means the sending mta sends the rejected email 
back to the user, so it wouldn't get caught in the spam trap[1].

At least if the email is rejected, the user knows that the recipient 
didn't see it. If its lost in the spam box, then the sender wouldn't know 
if it was received or not.

Scott

If you don't see any ham with a score above 5, why not set your reject to

IMHO its better for a sender to get "Your Mail has been rejected due to 
suspected spam", then the email getting lost in the spam box never to be

Really? I have been led to believe that as long as the network 
installation (permanent or not) is not connected directly to the phone 
line, then its OK.
That is, it is possible to use the same cat5e cable for phone (pstn) and 
IP network. This would be illegal to wire up without a license. 
If you simply wire up a LAN, and have an ADSL modem connected to the LAN, 
then you don't need to be licensed. (since the ADSL modem is responsible 
for protecting the PSTN network).

afaik tmpfs automatically resizes depending on how much is used at the

You can specify how much the maximum it can grow to by using size=nbytes 
(default is 1/2 your ram).

Does it have to be fdisk?
cfdisk is recommended over fdisk (at least on my dist), and from the man:
W  Write  partition table to disk (must enter an upper case W).  Since 
this might destroy data on the disk, you must either confirm or deny the 
write by entering `yes' or `no'.  If you enter `yes', cfdisk will write 
the partition table to disk and the tell the kernel to  re-read  the 
partition  table  from the disk.  The re-reading of the partition table 
works is most cases, but I have seen it fail.  Don't panic.  It will be 
correct after you reboot the system.  In all cases, I still recommend 
rebooting the system--just to be safe.

If you need to use fdisk, I guess you could find out what cfdisk does to 
re-read the partition tables and use that.

Cheers,

Scott

Re: [SLUG] Perl/SSH Problem

[Scott Ragen]

Why Choose not to use ssh keys.
The default is to both allow passwords, and/or keys.
You don't need root access to create a passwordless login (providing the 
admin's haven't explicitly changed the default).
All you do on your mail machine is use ssh-keygen to generate the key you 
want, put the private key in ~/.ssh/ (the name depends on what type of key 
you made, man ssh-keygen for details. Then put the public keys on the ssh 
servers in ~/.ssh/authorized_keys

That should basically be it.

Now the reason I suggested that is Net::SSH (Which cannot use passwords 
for login) uses Filehandles for reading and writing, so expect should 
"just work"(tm).

Scott

As far as I know, this states a session was successful via ssh (scp), 
perhaps there is nothing to place on the remote box? (eg, 
/usr/sbin/vmsnap_all didn't work)
What is /usr/sbin/vmsnap_all, is it a shell script? Perhaps it relies on 
environment variables that are not set in the cron.
After it is run from the cron, do the backups exist on the local machine's 
/vminages/localbackup?

Do you have any objections to using gpm in X?
you could try modifying your pointer section in your xorg.conf as such:
Device "/dev/gpmdata"

Restarting gpm as you mentioned might reset it.

Alternatively, if its a usb mouse, you could just unplug and re-plug it in 
each time.
If its a serial mouse, check out:

Hi Howard,
Just a guess, but have you tried overriding the MTU on the ipsec vpn?
To determine if this is the problem, try pinging the other side with a 
packet size of a little less then the ipsec0 mtu size. If you don't get 
replies, its most likely your problem.
If using openswan/freeswan/, use the overridemtu= in the setup section of ipsec.conf

Thanks for the replies. I have just talked to the customer, and they will 
be implementing IPSec shortly, so ssh tunnelling won't be needed :).
I didn't realise openVPN had a windows client, that could have been an 
option. I am not a fan of pptp, so that would only be a last resort.

The main reason I wanted SSH Tunnelling, is the server is already there, 
no installation needed on the server and they already use putty.

[SLUG] Locking down SSH for tunnel access only

[Scott Ragen]

Hi All,
Before I go ahead and suggest SSH tunnelling to a customer, I would like 
to get some suggestions on how to lock ssh down to only allow port 
forwarding. ie. a user ssh's into the gateway, which allows him to tunnel 
through to an internal web server.
I've looked at sshd's man page, and will adding the following to the users 
.authorized_keys (as well as giving the user a /bin/false shell):
no-X11-forwarding, no-agent-forwarding, no-pty, permitopen="host:port" 


I don't want the user to be able to scp, sftp, etc. There arn't any other 
services the user can access (no telnet, ftp, etc).

Thanks for any assistance.

Cheers,

Scott

Note that $ETH1 is the interface that is on subnet 10.0.1.0.
Also, I have excluded your tcp protocol and port, but you can add them if 
you want. You need to make sure you also masquerade dns requests if you do 
not have an internal dns server.

run "shutdown 22:00" to have it shutdown at 10pm tonight only.

I take it /usr/local/bin/perl is a symlink to /usr/local/bin/perl5.8.1?
If this is the case, I would suggest removing /usr/local/bin/perl, and 
reference the new version as /usr/local/bin/perl5.8.1
This will save any confusion if something goes wrong due to $PATH orders 
etc.

Yes, you will mostly need to installed modules them for each version.
You can simply 'perl -MCPAN -e shell' (for current perl)
and 'perl5.8.1 -MCPAN -e shell' (for new perl)

My experience has been that each perl version installs in its own 
directory, and has its own binaries etc.
eg, perl 5.6.1 could be installed in /usr/perl/5.6.1
The binary is /usr/bin/perl5.6.1 (and /usr/bin/perl is symlinked to it).

You should be able to safely install the latest perl from source without 
breaking the current version, or any OS dependancies, providing you keep 
/usr/bin/perl pointing to /usr/bin/perl5.6.1.
To then use the latest version, just put #!/usr/bin/perl5.8.1 (for 
example) in your scripts.
Call perl5.8.1 for any debugging, or installing modules etc.

Don't quote me on it, but I think apache will crash (as in 'stop') on 
reload if you have errors in your configuration.
You should be able to do a 'configtest' to verify your config before doing 
a reload (it may be different on different distro's).

I know I'm not answering your question, as it has already been answered by 
another. but do you need to shutdown apache before a restart?
If all you are doing is reloading a new config, you should be able to run 
'service apache reload'
This sends a HUP signal which tells apache to reread its configuration 
file, this will ensure (providing there is no errors in the config) there 
is no interruption to the service for anyone browsing your site.

Have a look at the cups error.log. On my Debian systems this is in 
/var/log/cups/ 
If that doesn't give enough information, try increasing the verbosity  of 
'Log Level' in cupsd.conf (debug2) restart cups, try printing again, and 
check the logs again.

You could try setting the --timeout= option of rsync to longer delays.
You could also try setting --bwlimit= which will limit the bandwidth

The command "stty olcuc" will give the results you mention.
That shows uppercase for stdout, but stdin is still case sensitive.
eg:

CONSBYCONTRACTORSCHEMA.XML
[EMAIL PROTECTED]:~$ LS
-BASH: LS: COMMAND NOT FOUND

The first command was done with 'ls' as input, the second with 'LS'.

Ohh, Cobol can use stty commands, as well as terminfo instructions.
I can also create a C library if it needs to be done like that - but I 
would like to exaust all other options first.

So does that mean if I include my website in my sigs to mailing lists,

Given that Microsoft have released a patch for the XBox that corrects this 
"feature" (stops you from installing Linux). On top of this, if you are 
online even without a live account, and access any live features in the 
game, it patches your system without permission.

This also depends on what the load the machine is using, If you run out of 
memory and swap, you would need to create more swap, or RAM, depending on 
your funds.
You don't have to re-adjust the swap filesystem, you can just add another 
one. you can even create it on another hard drive if needed.

[SLUG] Software RAID & LVM

[Scott Ragen]

Hi All,
I am considering converting our server to a Software Raid 5 configuration 
with LVM (Linear Mode).
Our server is running Debian woody stable dist.
Just wondering if anyone has had any experience with this kind of setup?
I have looked through the LVM and Software RAID how-to's and it doesn't 
look too complicated, but I won't know till I try it.
I would like to try it on a development machine, but the budget doesn't 
allow us to have one, so my first go is on a live system :(

If this is not possible to install the module, use the sendmail command
`sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED] < /tmp/mailout.$$`

(Remember, you will need to have "Subject: Your subject here" on the first 
line of of /tmp/mailout.$$)

[SLUG] Samba moving files

[Scott Ragen]

Hi All,
I would google search on this problem if I could, but I don't where I 
would start... so any pointers, or the answer would be appreciated.
My problem is:
A client ftp's files to our customer for processing, the connection goes 
as such:
ftp client> win2k-->through samba to Linux (S:\)
(They use the win2k box so the End machine isn't exposed, I know 
ridiculous using IIS as an ftp server...)

What happens is they ftp directly to the processing directory so the 
script is picking up semi completed files, and failing.

My question: What happens if they create a batch file on to the win2k box 
to move them from a temp directory to the processing directory?
Will it have the same effects as mv in Linux, or is this going to be 
pointless?

If this is fruitless, any suggestions on how this could be achieved?

TIA

[SLUG] Dailin from mobile

[Scott Ragen]

Hi all,
Sorry the subject is sketchy, but I don't know how to phrase this, but
anyway on to my question.
I might be reaching here, but is there any software for Linux that
anyone is aware of where it will allow a user to call the Linux box, and
then the user presses a few keys on his phone, for example: #212345 and
this will be dumped to a flatfile as the contents: 12345|$date|$time

I know this is a really sketchy question, and I'm not sure where to look
(Perhaps if someone could even email me the contact of a company that
could do this)

[SLUG] Filesystems....

[Scott Ragen]

Hi guys,
I'm a little confused by this, and although it has never caused any
problems, I am somewhat concerned about it.
I was looking at my partitions through fdisk and comparing them to the
mounted filesystems, and found an oddity (atleast it looks like one to
me)
An fdisk produces two partitions as below:

/dev/hda4   420  1216   6401902+   f  Win95 Ext'd (LBA)
/dev/hda5   420  1216   6401871   83  Linux

If you notice the start and end cylinders, they are both the same.
I have tried mounting hda4 to see what it is, but it comes up with the
wrong fs type etc.

Can anyone put some reasoning into what looks to be a computer
contradicting itself?

Cheers,

Scott

RE: [SLUG] Exchange Replacements

Samsung Contact (Formerly known as HP Openmail) might be the way to go.
It will also do the emails, and shared folders, BBS etc.
Its not free, but its not as expensive as exchange.
The only problem I have with it is it doesn't support Outlook 2002
(yet?).
Go to www.samsungcontact.com for more details.

G'day all,

I'm looking for suggestions/experiences in tersm of replacing exchange.
I've got the mail etc side of it handled, the only bit I'm having a
problem finding a decent replacement is for the calendaring/scheduling.
it needs to have multiple people be able to change appts etc. but some
people only be able to view it. Both public and private "diaries (or
calenders)" basically most of the everyday stuff you can do with
Outlook/Xchange. 

I've looked around and have seen a few, even though primarily they seem
to be web-based, not sure what I think of that at the moment. I was
actually after a bit of feedback in tersm of experiences people have
had. Doesn't matter if it's not free but at the same time don't want to
get caught up in licensing fee hell.

So any suggestions would be gratefully recieved..

Thanks,

Dan.

[SLUG] Perl - CGI: if statement

[Scott Ragen]

Hi all,
I have created this piece of CGI code (its probably bloated, but its my
first time!)
I have a few problems with it:

#!/usr/local/bin/perl
print "Content-Type:text/html\n\n";
print "\n";
if ($ENV{'REQUEST_URI'} = adl ) {
print "no Good\n";}
#print "\n";}
print ""

What I am trying to do is redirect 404 errors to another web server
which in turn goes to another, and could end up looping indefinably.
I want the if statement to say, if REQUEST_URI *CONTAINS* adl then print
"no good" (it will change but this is testing) else continue.

Another problem I have noticed, is it changes the $ENV{REQUEST_URI} to
adl, which is not what I want, I want it to be what it says.

Sorry if this abit hard to understand, but I am confused

Cheers,

Scott

I have two sound cards running in my machine, and both of them work fine,

How do you install over it/get rid of it/tell the computer "I don't

that didn't work.  Maybe I'm asking too much of my system :)

RE: [Re: [SLUG] Cron Weird Problem from a newby]

[Scott Ragen]

Louis,
Are you sure its a crontab problem and not just a path problem?
What I suggest you try is as root type: which crontab
it should give you the full path to the crontab binary, then as the user
type "path-to-crontab" and see if that makes any difference.
If it does, perhaps the users need the path to their crontab in their PATH,
to do this to existing users, edit ~/.bash_profile (~ means their home
directory) and put the path in "PATH=".
To do this for all new users created, place the same in
/etc/skel/.bash_profile

Scott

RE: [SLUG] memory above 64mb.

[Scott Ragen]

Hi Ben,
If they have only heard of MS Exchange and Notes, Notes has a version of
Domino for Linux (as IBM are big supporters of Linux). As for Exchange,
Samsung Contact (formerly HP Openmail) has an exchange like end user
interface. The reason HP sold Openmail was because Microsoft threatened them
as it was directly competing with exchange (These may only be rumours, but I
was told this by the head HP sales guy in Melbourne). It is also a cheaper
alternative.
The websites for these two are: www.samsungcontact.com (new)
www.openmail.com (HP's old website) and
http://www.lotus.com/home.nsf/welcome/domino

Give it a look and see if you can sway them.

They are thinking of putting in either Exchange/Notes/Groupwise as their
email solution. Why not Linux! Anyway i'm building a new box with Postfix at
the moment to see how it handles it. There is still the impression that
"where do you get support from Linux if no one owns it?" type of thing. As I
point out there are heaps of Linux savvy people and companies around that
can support it. Trouble is Linux is unheard of by the "IT steering
committees". They have only heard about Exchange and Notes. Linux needs to
get some credibility with the committees and bean counters before it has a
serious look in. How do you do that?

HI Slugs,

I have a compaq with 96Mb in it. it boots and counts 96Mb as I've just put
in 3x32Mb simms so that is all OK.

running "top" on Debian reports mem: 63352k av,

Does this mean linux is only "seeing" 64Mb?
Is this normal or should top be reporting higher memory available and how do
I fix it?

[SLUG] Failing Hardware - HDA: Lost Interrupt?

[Scott Ragen]

Hi guys,
On one of the boxes I maintain, is having problems with the box. It
mysteriously reboots and freezes (including the network).
The errors I get in the logs are:

Apr 10 19:10:44 fsbris kernel: hda: lost interrupt
Apr 10 19:10:44 fsbris kernel: hda: status error: status=0x58 { DriveReady
SeekComplete DataRequest }
Apr 10 19:10:44 fsbris kernel: hda: drive not ready for command

This happened every now and then, its not constant.
I also checked google, and it mentioned making sure the APM settings are
correct, and perhaps turning DMA off/on, and see if it helps. APM is not
enabled in the bios, or kernel (/proc/apm is not present), and I booted up
with lilo command ide=nodma The lilo command made it worse as when there is
a heavy IDE load the error message is constant, but it doesn't freeze or
reboot!

Could this be a hardware problem, or is there somewhere else I need to look?

Thanks,

Scott

Hi Scott,

Why do you use ghostscript (gs) to print?  Why don't you just pipe the ps
file
straight to lpr to print?

Chris

[SLUG] Printing Postscript

[Scott Ragen]

Hi all,
I converting html source into postscript then printing. (I use htmldoc to
change from html source to ps)
A small problem is when it comes to printing, it takes up to 2 minutes to
process one page with 'gs' before the print actually starts.
I can see the 'gs' process use up to 97% cpu and 5% of 128mb ram. What I
would like to know is there any way to speed up processing to say, a few
seconds? :-)
The reason is that we have customers that could print thousands of pages in
one print, and the speed is unacceptable.
If its important the machine is a Celeron 333Mhz, gs version 7.03, lprng
version 3.7.4 and htmldoc version 1.8.16.

Thanks,

Scott

RE: [SLUG] Copying with exclusions

[Scott Ragen]

To answer my own question, unless someone has a better answer, I could use:
# ls |grep -v ???G.DAT |grep -v ???Z.DAT |xargs cp /backup
Would this be the correct way? Is it suggested that I would tar then move,
is this quicker & safer?

Regards,

Scott

Subject: [SLUG] Copying with exclusions


Hi guys,
Just have a question about copying files from one directory to another with
some soft of exclusion string.
What my goal is, I want to backup all data from one directory in a
filesystem to another file system except ???G.DAT and ???Z.DAT (the
??? can be replaced with a * if necessary but not preferred)
I can do it with the "for i in" command, but is there an easier less
stressful way?
There is about 7-8 gig of data in total, (4 gig needed to be copied), and
approx 6000 files (4000 of which would need to be copied).

Thanks,

Scott

RE: [SLUG] Redhat Linux 7.1

[Scott Ragen]

Are you sure its the System that has a 1MB chip and not the graphics card?
I find it hard to believe a Pentium 100 would have 1MB Ram.
What OS has it been running up until now?

Regards,

Scott

Subject: [SLUG] Redhat Linux 7.1



To those familiar with Redhat Linux 7.1, I was intending to install this
version on my laptop- it's an old piece of hardware, an Acer Note Light. It
houses a Pentium 1 at 100MHz, 1 MB DRAM and a 774 MB hard disk.
Now is it a feasible idea for me to install Redhat Linux 7.1 on this laptop?
Are there any alternatives, any suggestions?

FW: [SLUG] MTU problems ??

[Scott Ragen]

Howard,
This is actually a known freeswan problem, you need to make the packets of
the freeswan ipsec* smaller then the ppp*. To accomplish this, put in your
ipsec.conf `overridemtu=`
Hopefully this will solve your problem.

Cheers,
Scott

RE: [SLUG] sms smash questions

[Scott Ragen]

Hey Steven,

http://www.styx.demon.co.uk/

sms_client is one I have used previously. It is written by people in the UK
and Australia (perhaps elsewhere too)
I think it works with Telstra, Also works with Optus  & Vodafone. (it has a
list of providers it works with on the front page)
Regards,

Scott

hey sluggers,

I am trying to make a sms smash solution atm.  I have configured it
upto the stage where i can get the smash daemon to get a message and
dial the telstra service.  After the handshake, smash does a kamakazi
and dies. It then redials.

What i would like to know is what should the default config of smash
should be to make the call to the default telstra number.
Alternatively, are there any aussie-network compatible sms software
out there that can use a dial up modem to send sms' ? Is Tel$tra the
only dialin point?

Cheers,
Steve

[SLUG] IP Changes

[Scott Ragen]

Hi all,
I've been looking for a good hardy script/program that will run commands I
specify when an ip address on ppp0 (adsl) changes.
I need to run commands like iptables restart, ddclient (to change the
dyndns.org dns) and restart the vpn.
Does anyone have any suggestions, ddclient apparently can, but I couldn't
get it to work because I think it performs the commands after it changes the
domain name, which it can't because of iptables firewall.

Regards,

Scott
