I use ispell in irssi, and it's not that good at unravelling the noodliness
of my mind and guessing what I meant to spell.

If one character is wrong, it will make the right suggestion, but if
two characters are wrong, forget about it. If ispell can't make a
suggestion, I then I google it, and google always knows what I meant
to spell. Pretty scary.

here's a weird example:

dribl

ispell says

& dribl 5 0: drib, dribs, drib l, drib-l, drill

aspell says

& dribl 19 0: dribble, drably, tribal, drill, dribbler, drivel, drub,
durable, durably, dbl, driblet, droll, drool, drab, treble, drawl,
trial, tribe, trill

I have heard in the past aspell is better, and I would concur.

I have no idea aboot secure boot, it might be the problem, no idea.
I have seen a linux appliance that wouldn't work after being dd'd
because the mac address changed and the ethernet device
became eth1, and the appliance had hard coded eth0 in it.

I can't see how that would matter in this scenario, but thought
I would mention it.

nice write up. thanks for that. laptops and SSDs are getting so cheap now.

I recently replaced my 2.4G wifi with a 5G on my dell inspiron something
or other laptop,
and it was a major pain. Granted no ribbon cables need to be removed to
replace the HDD,
but to replace the wifi I had 5 delicate ribbon connectors to deal with. I
only broke one. oops, but a piece of cardboard and it's as good as new.

I believe dnsmasq lets you change host addresses of single hosts in
a large domain with a 1 line entry, not a bind solution, but it's really
easy to do with dnsmasq, i have no idea how to do it with bind.

dnsmasq has this functionality for things like blocking ads, but you
can use it for any purpose

# Add domains which you want to force to an IP address here.
# The example below send any host in double-click.net to a local
# web-server.
#address=/double-click.net/127.0.0.1

# --address (and --server) work with IPv6 addresses too.
#address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83

# Add the IPs of all queries to yahoo.com, google.com, and their
# subdomains to the vpn and search ipsets:

I think apt-cacher listens on a port and you can connect
to it with a web browser to fix it. see /etc/apt-cacher-ng/security.conf
to set a password also try restarting the apt-cacher daemon

http://david:3142/acng-report.html

I had no end of problems with it, constantly had to restart it and 
delete/ //var/lib/apt/lists/partial/*
and often /var/lib/apt/lists/* too

I just use squid now, you just have to increase the maximum file size that's
saved to disk so debs get saved.

/root/.profile is only going to be read for root login shells, like sudo
-i or su -
you can set environment variables in supervisord config which will just
affect
the supervised program, or set it system wide which amos is going tell
you how

you'll have to check the docs, but I believe in your [program:x] section
you add

Did you install the 32 bit or 64 bit 12.04 LTS version?
if you're not sure, paste the output of uname -a

There's no downgrade option, you can restore from backups, but I would
recommend fixing the problem rather than going backwards.

The server runs on LAMP, so I guess WAMP and MAMP would work too, the

windows, linux, os x, android and ios and anything that supports a web
browser and or webdav. The server
also works with nginx, which is what I run it on. there are two .htaccess
files that someone has
converted to nginx

No experience, but dump the mysql db, the webserver config and backup a

held broken packages? I'm not sure what that means exactly, if it means they
were held manually, unhold them I would suggest.

I haven't fixed a broken debian package system for a while, but first I
would
disable any third party sources, then apt-get update.

if
dpkg --get-selections | grep 'hold$'
is blank, then try

apt-get -f install

also,

dpkg remove --force-depends somepackage
apt-get -f install

force depends to fix a broken system is fine, it's just not fine to use it
to install a package
on a working system though. (hello red hat of old)

find a nice area of space and run something like

#!/bin/bash
dmesg -c
cd /some/nice/area/of/space
while true; do
  d=`date +%s`
  tcpdump blah options -c 1 -w tout-$d
  if dmesg | grep "Bogus PPPoE length"; then
echo omg i think i found something | mail -s OMG y...@there.com
exit
  fi
  find -name "tout-*" -mmin +1440 -delete
done

run it in screen so it doesn't get hup'd if the ssh session closes.

completely untested, what it might do is
1. destroy your system.
2.
clear the contents of dmesg
write the contents of tcpdump to a file until it receives 1 packets
(adjust number to suit)
then tcpdump will exit and then grep to see if the error message is present
on your system,
if it is, email you and exit the script. I'm guessing the error is present
in dmesg,
then delete files starting with tout- that are over a day or two old
then goto beginning of while

also, to possibly trigger the error, try scping a multi meg file to and
from the location, the point being to
get a full sized packet going over the link in both directions, not
necessarily at the same time.

show the support people your evidence of high IO wait.

Also if they have a public forum, ask for help on their public forum
with the output showing high IO. If they're an au company, ask
for help on whirlpool in the appropriate forum, they probably watch

I know it's resolved, but look at the 6th column in the original post.
90+% iowait, 90% of the time, the cpu is waiting for IO.

now what you should do is run the same command when everything

Then when you have another problem, you can compare with

Re: [SLUG] Happy 20th birthday Debian!

Since we are being nostalgic, today (the 25th of August for those
earthlings living in the past),
22 years ago, Linus sent a message to the minix newsgroup announcing a free
OS that he had
been working on since April.

Linus today announced 3.11-rc7 as a homage to that famous message.
Also Linux 3.11 is code named Linux for workgroups, and rc5  was
released  the same day as windows for workgroups 3.11 was in '93.

eth0 is your lan cable interface, it has no ip address
wlan0 is your wifi, and it has no ip address.

So the question on the tip of my chicken lips is, what happened
to your router? In a typical home network, the adsl, or the wifi router
hands out the ip addresses.

Do you have the international symbol for radio waves at the top of your
screen? that's network manager, click that and go into it and see if
your wifi is connected.

what's your usual mode of connection, lan cable or wifi?

That will come in handy. I've got a dell/samsung(I think) printer connected
to my
odroid, which is arm. Unfortunately it seems to require a binary driver
which is
only available for i386 and amd64.

I tried using qemu to emulate i386, and with debian's multiarch support it
was surprisingly
simple to get going, unfortunately arm qemu is missing a piece of
functionality (futex) that
the binary driver needs. So usbip might be the way to go.

Re: [SLUG] python in linux mint

[Michael Chesterton]

Have you looked at the raspberry pi? it's designed for the classroom to
teach kids about programming and computers.

The ipython shell is nicer than the plain python shell and I'm sure there
are other GUI apps that I'm not aware of that do what you want, so stay
tuned ;)

You can run rsync twice on the one server

rsync -options server1:/dir1 /dir1
rsync -options /dir1 server1:/dir1

with the rsync options, you probably want

-u, --updateskip files that are newer on the receiver

you could also play with git-annex for a smarter sync. In a nutshell the
file metadata is
kept under version control, not the files.

There's also ceph, there was a talk on ceph at slug, i think, a few months

centos is good for somethings, but if you're going to add unsupported

a) it's an unsupportable mess. b) it's still centos

that is if you are using centos, i don't think you mentioned, I don't

Re: [SLUG] Fwd: Re: Smallest and Cheapest Linux Computer ?

[Michael Chesterton]

I use an odroid u2 as a server at home. It has the same problem as the pi
with usb ethernet and disk.
but it's fast enough to watch videos over wifi, so that's all I care about.

there are pi like boards that have sata, but the one I saw around the same
time I bought the odroid
had only one sata port, and I needed 2 or more. If i was going to use it
for a small business server,
i would want 2 sata ports for raid1.

odroid u2 is about $100 usd, quad core arm cpu, quad core gpu, and 2GB ram.
looks awesome, very few
cases available for it, but that wasn't important to me. It's basically a
short business card size pcb
mounted onto a heatsink. has an option for a fan for hot environments and
overclocking, but it runs fine without,
and has an option for what I think they call emmc storage, which from what
I can gather is really fast storage
with a micro sd interface. With emmc it compiles a kernel in a few minutes.

It runs on 5v 1amp (needs a 2amp PS for headroom and to power usb devices)

My first install was in about 95-96, there was some distro starting with y
that i have no idea how to pronounce or spell, I think slackware was
my first install, but I ordered a midnight magic cd and tried them all.
A colleague recommended debian and I switch to that.
Full time linux at home was pretty quick afterwards, and full time at
work as a desktop was probably sometime in the naughties.
I ran lotus notes under wine, which ran really well.

I'm not sure about using the remote hosts MIBs, I think the snmp protocol
is all numbers, and the client uses the MIBs to map numbers to names,
like DNS. But, it's been 5 years since I played with snmp, so I'm in no
way saying you're wrong and I'm right, I'm just offering what I remember.

   -m MIBLIST
  Specifies a colon separated list of MIB modules (not files)
to load for this application.   This  over‐
  rides  (or  augments) the environment variable MIBS, the
snmp.conf directive mibs, and the list of MIBs
  hardcoded into the Net-SNMP library.

  If MIBLIST has a leading '-' or '+' character, then the MIB
modules listed are loaded  in  addition  to
  the  default  list,  coming  before or after this list
respectively.  Otherwise, the specified MIBs are
  loaded instead of this default list.

  The special keyword ALL is used to load all MIB modules in
the MIB directory search list.   Every  file
  whose name does not begin with "." will be parsed as if it
were a MIB file.

   -M DIRLIST
  Specifies  a  colon separated list of directories to search
for MIBs.  This overrides (or augments) the
  environment variable MIBDIRS, the snmp.conf directive
mibdirs, and the default directory hardcoded into
  the Net-SNMP library (/usr/share/snmp/mibs).

  If  DIRLIST  has  a  leading  '-' or '+' character, then the
given directories are added to the default
  list, being searched before or after the directories on this
list respectively.  Otherwise, the  speci‐
  fied directories are searched instead of this default list.

  Note that the directories appearing later in the list have
have precedence over earlier ones.  To avoid
  searching any MIB directories, set the MIBDIRS environment
variable to the empty string ("").

  Note that MIBs specified using the -m option or the mibs
configuration directive will  be  loaded  from
  one  of  the  directories listed by the -M option (or
equivalents).  The mibfile directive takes a full
  path to the specified MIB file, so this does not need to be
in the MIB directory search list.

Use those options above, and if it works, then you might have a typo in the
snmp config file, or maybe it's in the wrong location.
strace -o /tmp/snmpwalk.out snmpwalk blah to see what config file it's
trying to open.

Sydney trains have been planning to computerise since the waterfall
accident. There will be constant monitoring of speed and position and
overrides if something goes out of whack, too fast, too close, or whatever.
Its primary goal is safety though, not efficiency.

I want to add a linux angle, but can't think of one.

Others have answered your question, I thought I'd chip in with why they are
saying it's a file system/disk issue.

That line above is the key, the 8th column is a D, that means the process
is in an un-interruptible state waiting on I/O.
You can't kill it, root can't even kill it. The ps man page has the text
book definition of processes in D, but D doesn't mean disk, it's any I/O,
it could be network, like an nfs mount.

if you ran dmesg before rebooting you might have seen some disk errors,
they still might be in a syslog file now.

It's mainly used for daemons like web servers and mail servers, so if you

If you don't have a valid fqdn just make something up, like

127.0.1.1 mycell.home mycell

or whatever, you could even leave the fqdn out and just have 127.0.1.1

It wasn't the cause of your problem, but it's not the best idea to put
my_hostname on the localhost line.
If you have a static ip for eth0 add a separate line like

1.2.3.4 my_hostname.my_domain my_hostname

where 1.2.3.4 is your eth0/wlan0/whatever address. If you don't have a
static ip, say a roaming laptop, use

127.0.1.1 my_hostname.my_domain my_hostname

That way forward and reverse lookups will make sense. If you do that, don't
forget to remove my_hostname from the localhost{,6} line.

Two things to check. When it doesn't work, check you can resolve hosts, ie
host google.com
also check your routing table for a default gateway and try a traceroute.

I could also be a duplicate ip or something weird like that.

when it's not working, try tcpdump -nvei eth0 and try ping google to see

LPS interests me, and from the very little I know about LPS and tiny core
linux (TCL) they seem similar in that they have a file system blob that gets
loaded into memory, so any malware can affect the files in memory, but if
you reboot, you get a clean slate.

The idea is if you want to do some (eg) banking, you reboot, do your banking
on a known clean environment, then after you've finished, you reboot again.

One of these days I will try TCL. TCL is run by the guy who was the work
horse behind DSL.

Ah, I maybe you need to run ldconfig manually after adding libraries to
/usr/local/lib?
I would try running as root on the command line
ldconfig

actually, before you do that run
ldconfig.real --print-cache | grep grits
then
sudo ldconfig
then
ldconfig.real --print-cache | grep grits

It's most likely included by default, but to double check, run

grep local /etc/ld.so.conf.d/*
(i get this as the output)
/etc/ld.so.conf.d/libc.conf:/usr/local/lib

Which means it's looking in /usr/local/lib for libraries.

run as a normal user, it will just print information, not make any changes.
It should be pretty clear if it finds a problem.

Here's an example I made up, I can't remember the exact wording.

ldd /usr/lib/libxml2.so.2
linux-gate.so.1 =>  (0x00d12000)
libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0x00cd9000)
libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0x00c5a000)
libm.so.6 => (missing)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x00e57000)
/lib/ld-linux.so.2 (0x004c)

So in my made up example, libm.so.6 is missing, and will need to be
installed before libxml2.so.2 can be used.

 and do the same to aweather while you're at it.

It's not what you asked for, but I like logcheck, it runs syslog through a

Brilliant, I never would have guessed, even though I have run into a similar
situation with start up scripts running before home was ready. If it was me,
I would put the authorized_key file in /home/sonia/.ssh while home is
unmounted. You just have to remember it's living in both places, it's there
when you aren't logged into the console, when you log into the console, it
gets hidden by the mounted encrypted drive and is inaccessible, but it's
already on your encrypted drive so both cases will work.

It's just a little fragile, because you have to remember if you update the
file you have to update it twice. But I could live with that.

You should file a bug with libreoffice. Oracle fired all the 100+ developers

I find packages for ubuntu by googling for the software name ppa, ie google

You could also try a libre office ppa, it might have a later version with

The trouble with that approach is the backup doesn't contain the mount
points for the excluded file systems. So when you restore, you have to
create the mount points manually.
IMO, it's better to list all file systems you want to backup, and then
backup with --one-file-system or equivalent.

 I believe the old stable 2.6.18 kernel on linode doesn't support ipv6
connection tracking. If you're running that kernel, swapping to the new
linode kernel will solve that.

I know you recommended not to do it, but I wouldn't have even mentioned
the possibility.

There's one semi good reason that I know of to use force-deps on 
a working system, it's otherwise there for emergencies like 
a broken dpkg database. 

Occasionally you might use it to purge a package temporarily, 
and reinstall it straight away, if the package has other packages
depending on it, and you don't want to purge them too. 

In the old days, it was standard to see instructions using no-deps on
rpm based systems, and it caused a lot of pain. Basically once you've
used no-deps once, you have to use it every time.

Yeah, that's one way, or look around in backports or ppa repositories.
If you back port it yourself, it's up to you to keep it updated, if you
can find it in a ppa or backport repository, someone else will do it
for you (you hope).

Not really, maybe that's not the best first step, anyway.

Try playing with ping and mtr, change the size of the ping packets,
A ping -s 1472 will give a 1500 byte packet. It's a bit hard to
workout the speed based on rtt because your link is asymmetric,
but you can compare rtt between different distros. Ping your gateway
for a test, rather than mirror.aarnet.edu.au.
 
There are tools that works out the speed of an asymmetric link, though

The IPv6 issues where mainly with firefox, and the symptoms were different
to yours, mainly a page would take ages before it started to load, then it
would load fast.

Some issues that can cause problems are MTU and duplex mismatch.

I don't think it's one of those, but they are easy to test.

Run ifconfig and look at the traffic stats on eth0 (or whatever your network
interface is), see if there are any errors or collisions.

run ifconfig eth0 mtu 1000 and then try a download. ifconfig eth0 mtu 1500
to reset (if it was 1500 to begin with)

It could be some weird tcp setting, have a look at /etc/sysctl.conf to see
if kernel parameters are being set. If you're up for it, have a look
at /proc/sys/net/ipv4 and compare between knoppix and debian to see if there
are any differences. There's lots of files though, you can cat them to see
the settings.

Lastly, run
tcpdump -nvvvi eth0 -s0 -c100 >/tmp/tcpdump.out
then do a download, maybe use a pastebin to upload the data and link to it
in a follow up post rather than pasting it into a message to the list.

I personally don't think it's worth the hassle these days. Years ago it used to

very effective, now, not so much. Some spam now retries, or they just send it

I rely on RBLs and spamassassin, and they are effective for me. The spam that 
did
get through were to poker sites, and I fixed that up by adding rules to 
spamassassin.

I think spamassassin has a db that needs daily updating, is that happening?

I've configured my servers to only allow 3 ssh connections a minute.
It stops most brute force password attacks, but not all. When they start
timing out, they usually move on. Some just slow down.

There's other software like fail2ban and at least one other i've forgotten
the name of. They run as root, and periodically scan the logs and insert 
rules to block ip addresses if they have too many failed password attempts. 

I decided against fail2ban in favour of rate limiting ssh connections.

I've thought about doing the same, but it's only a bandaid. It might stop the 
zombie
probes, but won't stop a targeted attack, which will use a compromised host in
australia to relay through and probably break in through the web server.

What sort of attacks are you seeing? A lot of the attacks I see are harmless 
zombie
probes looking for old and well know exploits on unpatched systems, or brute 
force
password attacks on ssh.

ie if you keep your system up to date, and use good passwords, or better, keys, 
you
shouldn't be bothered by the probes.

The biggest risk as I see it is the web software, sql injection, xss, etc. As 
far as iptables
is concerned, it's legitimate traffic, you need to look inside the web requests 
coming
in, ie deep packet inspection. Also do penetration testing. 

If you're running apache, look at mod_security.

yes.

Take your time and learn both. I take it you're looking to get experience for
work? Both are handy to know. 

If you have, say, a gig+ of ram, you can install virtual machines of centos for
playing on, get bored with it, delete it and install debian, etc.

If you have $20/month to spend, you could get a vps from linode which you
can play with email and web servers. But of course you can do all that from
home without spending money, but if you have a dynamic ip it's not going to
be the same experience as an internet connected vps.

I don't think crazydomains offer a dns service, at least not for free. Whereas
the slightly more expensive registrars sometimes do. 

There are some free dns servers out there, but IMHO the best one got bought
out and I don't think it's as good as it was anymore. I'll leave it up to you 
to google
for them.

Basically, you need 2 or more dns servers (which have static ip addresses) to 
point your crazydomain to, then you set up the dns with whatever you want with 
a short ttl, say 300 seconds, and update the dns (not crazydomain) every time 
your ip changes, presumably programmatically and automatically.

I hear you. I think it's possible, though, to filter direct mails
into the list folder. Obviously not with the List-Id, but some

You might end up with duplicate emails in the list folder,

I think because we've always done it this way, it won't change. Also, we are 
open source
advocates (don't look at my useragent) and open source mail clients supports 
lists very
well. There's usually a list reply button or key press that does the right 
thing.

We are also fast learners, so if we make a mistake in list etiquette, someone 
(or five) will
let us know. Like top posting. (but that's a losing battle) 

Personally I find lists and people setting reply-to annoying. I mean how 
important are you
that you can't be disturbed by an email in your in box. There's also the option 
of filtering the direct emails so you never have to see them. 

How you want your replies handled on lists can be done with the Mail-Followup-To
header. Then you (and everyone else) use the followup function of your mail 
client, 
rather than reply.

Both google and yahoo have firefox plugins that might help diagnose the

Does the page wait for a few seconds on a blank screen and then download

Does that fix all protocols, or just tcp?

Google released a study to suggest heat didn't affect the life of a disk much.

I don't think multiples disks in a machine affect failure rate, it's just that 
the more
disks you have, the more likely you are of having a dud one that will fail. 

It doesn't matter how the disks are arranged, if a company has 1000 PCs with 
a single disk in each spread throughout Australia, they're more likely to see a 
disk fail than if you have one PC with one disk.

Do you get that with both fedora and ubuntu.

The only thing i can think of is the icmp message is being blocked.
Do you have any iptables rules, filter and/or nat?

i guess that's mount / -o remount,ro

I'm curious about the order of the read-only command, and the syncs. I did

there would be nothing to sync on a read-only file system, but I take it sync 
works
below the file system level?

I had a similar issue with 9.10, but different brand video card.
(it was fixed a day or to after release)

The way I "fixed" it was to ssh into the box and kill gdm, the old behaviour 
was if X died a few times in a row, to stop trying to restart it. Didn't seem
to be the case this time.

If you can't ssh in, at the grub prompt when you first turn on the computer 
there 
should  be at least 2 linux boot options, the second one should be safe or 
rescue mode, I forget the exact term. Try that to see if you can then access 
the console and look at the logs.

I've heard with some types of failures, sealing the drive in air tight

I think there's a tafe course run from granville that covers LPI.

Everything looks a little out of date, but Geoffrey Robertson looks

Re: [SLUG] comparing domain registrar prices

Dear Lazy Web,

I did actually try to find this on my own, honest!

Is there an equivalent to whirlpool.net.au for domain name registrars?
I.e. a single site which allows me to compare pricing over all of the
Australian domain name registrars?


In the fine tradition of not answering the question asked.
name.com does $6 domain names. I don't believe they
do au domains, though.

Now, one last question :))

In the DSL-502T, there is nothing that comments on MTU *but* there  
is a option to change the MRU' which is currently 1492 (when  
Columbus sailed the ocean blue)...are these related? Errr, not  
Columbus but MTU/MRU


I've had trouble finding if they are the same or different elements.



From memory, MRU maximum receive unit, I've seen it with PPP.

Sure, minus 36 from it and see what happens, you're not going to hurt
anything. Change it back if it doesn't have the desired result.

For the more sensitive of our members, please accept my apologies

Thanks Michael.

sudo ifconfig eth0 mtu 1464

was the sweet spot. My problem with uploading and sending large/ 
long e-mails is now resolved.


It might be that adjusting settings in the VoIP or router will fix it  
too. Lowering the MTU
on the router adsl interface by 36 bytes might work, too. Then it's  
fixed in one place,

you won't have to touch your desktops.

One last question. How do I fix the MTU setting so I don't have to  
reset it each time I reboot. For my desktop this is not really a  
problem - it's on 24/7, but I'd rather just have it sorted.


It depends, it depends on the distro, how new it is or how it's  
already configured.

I guess I would probably edit /etc/network/interfaces and add

up ifconfig eth0 mtu 1464

to the eth0 stanza. I'm not sure if the interfaces file supports  
setting MTU or whether
you need to do it like I did above with an up command. Also,  
NetworkManager

complicates things.

Yes, should have at least tried to look first :)

Given (as below) the current MTU is 1500 and you're suggesting  
changing this to 576, what are the consequences I should be aware of?



It's just a temporary change, next reboot will reset it, it  
determines how big packets
leaving your interface will be. But if you get it wrong it could  
cause your NIC to

catch on fire (I'm joking, there's nothing to worry about)

sudo ifconfig eth0 mtu 576

to reset

sudo ifconfig eth0 mtu 1500

but you don't even need to change the MTU, you can test the same  
thing with ping


ping -s 100 google.com
ping -s 512 google.com
ping s 1472 google.com

(1472 will give you a packet (frame i guess) size of 1500)

Re: VoIP adapter configuration was /Re: [SLUG] Thunderbird send problems

[Michael Chesterton]

sorry, another brain fart

it's

ifconfig eth0 mtu 576

but try the pings, see if you can find the maximum size that gets  
through.

Well, that's assuming it's an MTU problem.

PS. This problem exists on all three machines (desktop x2 and

MTU I mean, sorry.

ifconfig mtu 576 eth0


you could also try

ping -s 1472 google.com
ping -s 512 google.com

etc
