Interesting.  I had a similar experience with the Ubiquiti AirControl2 and 
Cisco ASDM software, which is so slow as to be unusable, but other applications 
run perfectly fine.

NetBeans, Eclipse, AirControl2, and Cisco ASDM are all Java–based, so possibly 
some correlation there.

So far I haven’t found a direct cause, although I have an NVIDIA–based system 
where they run smoothly, but all the machines that have issues are Intel–based. 
 I don’t have any Radeon–based systems, I’m afraid.

Re: [SLUG] ubuntu unity slow

[Amos Shapira]

Sounds like you have correlation between Java and slowness.
What's the Java configuration like? Do you tweaked the JVM settings to take
advantage of the larger RAM, for instance?

Re: [SLUG] ubuntu unity slow

[David]

if I wasn't so committed to Ubuntu I would have ditched it by now... 
it's painfully slow


I stayed with Unity because that's what Ubuntu is doing and I didn't 
want to be Canute, but I have no idea what they were thinking with Unity.


Sorry... that doesn't help debug it :(

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
what happens.

When I start up my system (Athalon ii X4, 8GB, Ubuntu 12.04) it will

I know that the net is working as my other computers will happily
connect to the net using my wireless lan and what makes it even more
wierd is that:
a.  If I boot my computer using PCLinuxOS it connects to the lan and
works perfectly every time,
b. My laptop ( i3 4GB ACER) runs on Ubuntu 12.04 and always connects
without a problem.

My laptop and desktop have identical setups (barring the appropriate
drivers for their devices).

As my desktop will talk to the router I assume the problem must be in
the way that they communicate but am having trouble finding the problem
as it seems to fix itself randomly. The problem did not exist with
earlier versions of Ubuntu.

Could be DNS.

Try setting the DNS servers manually, not to the address of your router.
You can do this in the network settings of your machine having issues, 
or you can set your router to give the actual DNS server addresses when 
handing out addresses in DHCP rather than the router address and passing 
through to DNS servers. This is an issue I have encountered in the past, 
so is worth a go.


Ultimately the best solution is to use Mageia for everything, always :-P
Let the distro wars begin :-)

When you upgrade from one version of Ubuntu/Debian/... you are asked, 
during the set-up phase of each relevant package, if you want to replace 
your old configuration file with the one provided by the maintainer of 
the package. If you say yes then you lose your old configuration file 
for the package in question and a new one is provided.
Often this is no problem, but if you have personalised the package - 
such as setting up your network - then you need to either retain your 
old configuration file OR go through the process (of setting up your 
network) again, from scratch.


Hope that helps.

Hi Nico,

I loaded 12.04 onto my laptop and all went well. I use wireless access
to the net constantly and it works perfectly.

I can only guess that something went wrong with the load.

Firstly check the set-up in your network manager. You may have
accidentally replaced your old configuration file with the new "network
configuration file provided by the developer" and may need to go through
the set-up process again.

If you installed/upgraded over the net you may also need to do an
"apt-get -f install" to fix anything that did not install properly. This
happened to me when I upgraded.

Oh , and make sure that you have rebooted at least twice since the
upgrade. I don't know why but this helps.

Did the reboot and, on a whim, put the MAC address of the router (BSSID)
and that of my WiFi card and all now works.

ifconfig, route and /etc/network/interfaces were all identical to the
working system.

Not sure why the BSSID had to be there but it now works.

Re: [SLUG] Ubuntu touchpad issues

[Edwin Humphries]

OK, this is weird. I did as you suggested (thanks, Peter), and the 
mouse-related output in the log looked reasonably similar to the 
touchpad output- and whilst I was comparing the two, the touchpad 
started to work! So I unplugged the mouse and rebooted, and after  
logging in, the touchpad didn't work - for about three minutes, and then 
it was OK again. So there's some weird delay going on.

A USB wireless mouse plugged in to the Acer works fine; however nothing

The "Synaptics TouchPad driver for X.Org server" is installed and after

the device and provides for its configuration. But neither actually do

I've added 'GRUB_CMDLINE_LINUX="i8042.nopnp"' to the grub conf, and the

I'm on a T-series ThinkPad too and there were simple things that just
flat out didn't work after the upgrade e.g. I couldn't maximise a
window, it'd just vertical maximise to one side of the screen.

However, this morning things are looking really good with my multiple
monitor setup and working how I would expect - I think I know why.

Before the upgrade (and for some time) I've had a few bits of custom
Compiz config, nothing crazy although I guess some people call wobbly
windows crazy :) My hypothesis is that this custom config was
interfering with Compiz/Unity and that was the source of my post
upgrade woes.

Why do I think this? Well yesterday I was using my notebook with no
additional screen and I needed to just Get Stuff Done so I battled
with Unity to try and get a working environment. This involved a bit
of research and resulted in running `unity --reset`, which resets
(amongst other things?) your Compiz config.

Hopefully that might help others. If all else fails and you want to
give Unity a red hot go, try running `unity --reset` and
restarting/logging back in.

Cheers,

Henare

If you installed without fiddling, then you need apt-get install gnome
before Ken's 'just click' will work.

I just tried all the gnome options but was unable to get right-click the panel 
(task bar) to offer the usual Add-Widgets etc.
I will spelunk, does xfce off weather and cpu-freq aplets?

But ... it seems to me that Heracles' advice is ummm sound!

My colleague had a new install of 11.04 for about two weeks and
upgraded to 11.10 yesterday, on new T-Series Lenovo laptop.

Took me a while.

Click on you user name.

A gear will appear near your name,  you can then select classic Gnome
from the start up.

Personally I have moved to XUbuntu and xfce.  Seems to work OK for me so
far.  I did this by installing xubuntu and then using the gear wheel to
select xfce.

I don't mind Unity but I DO mind that (as it appears from the 2
minutes I had to look at it) NetworkManager fails to find dbus and
takes the network down with it, so now there is no network until I
find time to figure this out...

My Twitter feed has been a torrent of rage and bile since I made the
mistake of thinking this was 2011 and I could safely upgrade my distro
without it being a catastrophic 90s-grade failure.

Ahh, that feels slightly better ;)

In all seriousness it's been OK fighting^Wusing it today but that's
because I'm not using "advanced" features like two whole monitors.
Since it took Linux about 10 years to get multi-monitor working last
time I'm guessing it'll be another 10 until Unity sorts that out too.

Yours grumbly,

Just for the record

A simple upgrade to the 10.10 using the Synaptic GUI worked perfectly 
first time. I'm not sure why the release notes were so cautionary. Maybe 
any problem had been fixed in the meantime.

Hi,

I have the 8800GT, and have had no problems with 10.04, 10.10 and 11.04

Not sure of the differences.

My way of upgrading that gets a machine back to what it was fairly 
easily, and also gives a recovery point. Used multiple times with good 
results while some dist upgrades failed, sometimes a contents of chair 
problem.


http://www.cyberciti.biz/tips/linux-get-list-installed-software-reinstallation-restore.html

Hardware and Software failures are part of Life. That is why you need to 
have a backup. I have already written about backing files and MySQL 
databases. You need not to backup all installed binaries (mostly 
software) with following tips. It will not just save your time but both 
Debian and RHEL distro can update them instantly.


In order to reinstall or restore your installed software you need to 
have a list of all installed software.

Task: Backup list of installed software

Debian Linux
If you are using Debian Linux use dpkg command to list installed software:
$ dpkg --get-selections

Store list of installed software to a file called 
/backup/installed-software.log

$ dpkg --get-selections > /backup/installed-software.log

RPM based distributions (RHEL, Fedora Core, Cent OS, Suse Linux etc)
Use rpm command to get list of all installed software:
$ rpm -qa
OR
$ rpm -qa > /backup/installed-software.log
Task: Restore installed software from backup list

Now you have a list of installed software. After installing base system 
you can immediately install all software.


Debian Linux
Debian Linux makes your life easy. All you have to do is type following 
two commands:

# dpkg --set-selections < /backup/installed-software.log
Now your list is imported use dselect or other tools to install the package.
# dselect

Select 'i' for install the software.

RPM based distro
As far as I know RPM based distro does not offers dpkg kind of facility. 
But with little shell scripting technquie you can easily install all 
software:

# LIST="$( cat /backup/installed-software.log )"

If you are using yum, type the following for loop to install all software:
# for s in $LIST; do yum install $s; done
Update try out following command (thanks to gt):
# yum -y install $(cat /backup/installed-software.log)

OR if you are using RHEL (RHN subscriber) :
# for s in $LIST; do up2date -i $s; done

Alternatively you use following command:
# up2date -i $(cat /backup/installed-software.log)




If you want to repeat installation of all packages from your computer to 
another one their is ideal solution to create list of all installed 
packages on your computer. Open shell and type:


sudo dpkg --get-selections >
installed-programs

File"installed-programs" will be written inside your Home folder and you 
can copy this folder. On another computer (computer on which you want to 
import this list) type:


sudo dpkg --set-selections <
installed-programs
sudo dselect

This procedure will mark all inside list for download, and then it will 
start will downloading and installation. Note that you also need to copy 
file /etc/apt/sources.list. You also need to refresh files database with 
command


sudo apt-get update

I recently upgraded from 10.10 to 11.04. It was the smoothest upgrade I've 
ever had with Ubuntu, or windows for that matter. Only Issue I had was 
something funny with the task manager causing it to flash - very anoying. 
Solved by a partial profile reset, wihich solved a heap of other niggles as 
well. Even my multiseat kept working. Oh and one of my DVB tuners dropped out 
of existance, but another one came back, why can I only get 2 out of 3 
working?

What are you backing up? anything that you can't afford to loose over an 
upgrade should have already been backed up!

cheers

It’s not like even officially supported upgrade scenarios go remotely
smoothly.

Fortunately dist-upgrades rarely eat *all* of your data.

Try in System/Administration/Software Sources select tab "Updates" and
change "Release Upgrade" option from "LTS release only" to "Normal
releases". Perhaps this change return upgrade-to-new-distribution

I'll throw my 2c in the mix for a little alternate perspective.

Firstly, the only times I've had any significant problems upgrading Ubuntu was 
when I went from Hardy 8.04LTS directly to Lucid 10.04LTS (which was/is a 
supported upgrade mind you).  This really was a collossal cluster fsck...but 
probably my doing; I had some custom repos in /etc/apt/sources.list, simply 
changed all references of "hardy" to "lucid" and did an "apt-get update && 
apt-get -u dist-upgrade".  This resulted in a completely neutered weekend and 
is NOT the way to upgrade (read about it here: 
http://gray.net.au/article.php/2010100401).  The correct way is to use the 
upgrade manager (full details here: 
http://www.ubuntu.com/download/ubuntu/upgrade):

1. sudo apt-get install update-manager-core
2. sudo do-release-upgrade

The only other upgrade hell I entered was when I went from Hoary (5.04) to 
Breezy (5.10) which left some KDE packages in a mess (read about it here - 
http://gray.net.au/article.php/20051016111619198).  Given the age of the whole 
Ubuntu (and especially Kubuntu) platform in 2005, I'm not entirely surprised.

So one borked upgrade as a result of PICNIC (Problem In Chair, Not In 
Computer), and the second probably due to immaturity in the platform (Kubuntu), 
I haven't had any problems since.  In fact I recently upgraded ALL my 10.10 
systems to 11.04 (some desktops, some servers, some virtual/guest, some 
physical) and NOT ONE has had any problems...and I absolutely slam my machines 
;)

Ubuntu is now quite a robust distro and the upgrade manager makes the whole 
process relative painless.  As always, backup before upgrade.  Personally, I'm 
quite happy with the 11.04 release and I'm enjoying the version bumps on a 
number of packages which have made a whole new set of goodies available.

Have fun.  Usual disclaimers apply.

Cheers,

James

10.04 is the LTS version, so he may want to take that into account

Not that I'm any Ubuntu expert, but from many accounts on the Ubuntu forums, 
you apparently want to avoid going to 11.04 just yet. 

And I personally had problem with 10.04. So go to 10.10 direct.

I have never experienced a seamless upgrade of any Ubuntu
distribution, so I second the recommendation to do a full backup
before attempting the upgrade. Ubuntu does some fairly vast changes
between revisions, and seeing as you're skipping a whole major release
in the upgrade, bad things could happen.

As for what to backup with, I use ddrescue as it has a nicer interface
for showing copying speed and error rate.

Do proper, full backup (dd is my personal favorite, but I guess there
are more sophisticated tools nowdays), do the upgrade and test if
anything went wrong?

If it is 'complicated' unlikely that anyone can answer your question
(although you may get some misleading 'everything went fine' emails) ,
so full backup is a must anyway.

Good luck!

My mate, a lecturer at curtin uni uses and likes evolution because it works 
with the uni's exchange server.
I find it a help to know a thing can be done, I hope this inspires you.

Replacing drives with smart errors and reinstalling seems to have fixed 
things, and the machine boots much faster now.

Thanks all

Check that your SATA cable is properly seated at both ends and check the
connector ends for cracks, particularly the end that plugs into the hard
drive.  Also Check the SMART status of your hard drive for possible faults.

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?

The ubuntu 10.04 and fedora 13 workstations connect thru a Netcomm

Tried #tracerouter --mtu gmail,com on both workstations.


Ubuntu 10.04 failed with same problem, before using launchpad, what

The 3G infrastructure and the BigPond infrastructure are not the same.

In any case, it's an Ubuntu bug.  Disconnect from the 3G service.
Edit /etc/resolv.conf to add
   server 10.11.12.13
(or any IPv4 address) and then reconnect to the 3G service. For
some reason Notwork Mangler doesn't like editing an empty

DJB made it Public Domain AFAIK, so I made a git repo from it and added
some of the published patches as well as my own work.

Yes, that's really nasty, but that's the exact problem I fixed recently
(i.e. about 6 months ago). The fix is that although dnscache is resending,
it should still accept late replies from the original requests it sent.

Performance starts to degrade as soon as the average request latency
exceeds 1 second. See http://www.nick-andrew.net/ actually it is my
most recent news item (I don't update it all that often).

Negative unfortunately; I discovered this problem on a modern day Mobile

iView uses the following config file for redirecting you to a special
unmetered video source:



The server it is on, www2b.abc.net.au, resolves to the same IP address
from home, as well as from Fremont, CA.

So in that particular example, it's IP-based, not DNS-based, thank goodness.

www2b.abc.net.au appears to be the ABC's "Windows box" from what I've
seen from the outside. It's the box that runs their tacky message board,
as well as serving out various stuff from hidden URLs, usually that are
quite hard to get to.

Really?  That bites.  Most CDN networks have arrangements so that this works
regardless of which DNS server you use.

Can you point to an official document stating that?  I checked, and I found
some unofficial comments on Whirlpool, but nothing I consider authoritative
from Internode. :(

Oh, cool.  Someone talked DJB into relicensing dnscache so that it can be
distributed patched, rather than requiring the original.  That must make life
better for folks like you who want to use it.


Anyway, I have a bit of an aversion to the software: aside from the (formerly)
awful license conditions, I had a couple of clients who ended up with really
nasty problems from dnscache.

(Executive summary: probably not a problem any more. ;)


Way back when a 256/64 kbit ADSL connection was fast and expensive, a couple
of places I supported used software that incorporated dnscache, and had the
ability to use DNS RBLs for inbound email.

So, it turns out that dnscache had a fixed ten second timeout for a response
from the upstream DNS server.  If it receives a reply outside that window it
will reject the reply; it also resends queries if they time out.


Apparently, though, if you manage to list enough RBLs you can get in a
situation where dnscache is sending requests, which all time out because the
link RTT is more than ten seconds — just from the load of sending
retransmitted queries.

Which meant that two or three emails inbound at once could result in a
situation where their network link got saturated, and stayed that way until
dnscache gave up on all the queries.

Gosh, was that fun.


Anyway, these days that is unlikely to be a problem: either the code will be
patched to play nice, or the increase in bandwidth makes the odds of breaking
pretty slim.

I use '8.8.8.8' as my DNS resolver in network-manager for my Next-G
connection, and it appears to work fine.

The reason why I set a manual one at all is because actually getting the
autoconfigured DNS addresses is flaky. Either Telstra doesn't bother to
serve me the DNS servers half the time, or something isn't picking them
up correctly.

Re: [SLUG] ubuntu network manager dns

[Martin Visser]

Also be aware that there some ISPs tend to a few things with DNS

1. Some do block access to their DNS from outside of their network. I think
this is mainly because they don't want to provide a service to the wider
Internet that potentially means their own customers get impacted by DNS DOS
attacks or simply heavy load. Certainly Telstra did do this as their DNS
became well-known in Australia.

I recently implemented a fairly large enterprise and Internet facing DNS
environment for a telecommunications customer recently and the legacy
environment was being impacted quite heavily by non-customer load.

So while you may have some Telstra DNS server addresses, they may be being
blocked from their mobile/3G network to minimise unplanned load.

2. DNS can be used to help direct the subsequent application traffic to
particular managed servers. For instance, Internode provide unmetered
content to their customers, one of which is the ABC iView service. However
at least in some part, probably because of the use of content-delivery
networks, Internode ask to make you use their DNS. I presume if you don't
their is a risk that your ABC iVIew traffic gets directed to servers other
than those Internode can provide unmetered traffic for, and hence you think
your iView is unmetered but is in fact coming from outside servers. And as
James Gray has said DNS can also be used as a poor-mans way of filtering
traffic - by giving NXDOMAIN or other redirections when you try to resolve
the name of an "undesired" service. (And of course hijacking legitimate DNS
services, through cache poisoning and the like, is one way the bad guys can
you fool you to visit them instead of your regular programmed service).

Most Interrnet service providers do list what their recommended DNS is for
their service. Usually you can implement your own or choose your own DNS
service, but you need to be aware a little of what you are doing.

Unless Senator Conroy gets his way, then we will all be forced to use the ISP's 
DNS servers, or fall-back to using some sort of VPN/tunnelling to get out of Oz.

FWIW, I got very sick of this years and years ago, so I took to installing the
distribution packaged version of bind on my machine and configuring the system
to use localhost for name resolution.

That gives a pretty solid resolver that just works(tm) anywhere, and while
there is a tiny increase in first-access latency to sites I can't say it has
any significant practical drawbacks.

Just a thought but I put my DNS addresses in the prepend statement in
dhcp.conf and all works fine. I use a BLiNK usb modem on Ubuntu 9.10
when I'm using my laptop, not telstra but the systems should be similar.

 What do you mean by "pinging a web address", the name of the server? If you
can ping a DNS server by it's IP address, but not by it's fully-qualified
domain name (FQDN), then you can stop right there as your DNS
configuration/connection is not working. (Being able to reach a site using
PING only really tests that you can reach it with the ICMP protocol over IP.
It doesn't test anything more about reachability to a particular host, the
initial DNS lookup done by ping if needed is really just a side effect).

To test DNS, once you think you have resolv.conf correct, use "host ".
If this returns nothing, then DNS is broken. You can make it more verbose
with "host -v ".

You can also use "host" to force it use a particular DNS. For instance
Google have magnanimously made available 8.8.8.8 as a freely available and
easily remembered DNS. To test it you can do something like "host
www.google.com 8.8.8.8" to get the following result.

$ host www.google.com 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

www.google.com is an alias for www.l.google.com.
www.l.google.com has address 74.125.19.106
www.l.google.com has address 74.125.19.147
www.l.google.com has address 74.125.19.99
www.l.google.com has address 74.125.19.103
www.l.google.com has address 74.125.19.104
www.l.google.com has address 74.125.19.105

Of course you could test that you can directly reach the Telstra DNS (using
DNS) by this method. If explicitly doing a DNS lookup against those servers
does work with say "host www.google.com 1.2.3.4" where 1.2.3.4 is the DNS
server you are hoping to use, but plain "host www.google.com" doesn't then
your DNS config is broken.

ping only works for IP addresses or properly formed DNS names - never URLs.

I don't experience with Ubuntu Server LTS so will try to avoid a flame
war by commenting on it.

I'll try to help you focus on what I believe to be the question which
should matter to you the most - which distribution and version will
help you spend the least amount of time on active support and you
expect things to "just work" for you?

This is a relatively personal question - it depends a lot on your
personal experience and in which distro you feel most comfortable that
"you can tuckle anything in the quickest way".

If you want to install Distro X at a remote client site, I think you
better gain some time of hands-on experience with it, its community,
nomenclature, terminology, time lines and record in supporting the
version you are going to install.

Remember that unless the customers are Linux system admins themselves
(even most "professional programmer" do not count), they wouldn't care
less if the filesystem is ext4 or Reiser5, or that the system can boot
a minute faster or has glibc 2.10-1. All they care is that the server
will "be there" and be up every time they try to use it. For your own
sanity, you should care about things like stability and security
updates - again in the name of spending the least amount of time
keeping it up to date and resistant to security attacks.

Hope this helps,

I ran my server (LAMP Mail and DNS) on ubuntu for a couple of years without 
problems and with quite positive impressions. Eventually I needed new compiler 
and qt4 support for my mythtv and at that time I let my preference for yast 
prevail.
The advantage of LTS was a quite nice LTS-LTS++ upgrade where as upgrading 
version to version was much more iffy - sometimes OK, not always
So if you were going ubuntu i'd install the last lts then upgrade and not 9.10 
to next LTS.

yeah go 9.10, it seems pretty spiffy from a desktop POV.

I have found ubuntu server upgrades to be much nicer than the average 
desktop upgrade, I spose there is less stuff on a server and hence less 
to go wrong.


I wouldn't be too worried about tracking the current release on a 
server, give it a month or two after release to make sure any kinks are 
worked out and go for it ;->


But then I have only updated as needed for hardware support and feature 
additions, like somebody said if it ain't broke.

An upgrade from Ubuntu 8.04 LTS (ext3) to Ubuntu 10.04 LTS will in all
likelihood continue to use the existing filesystems as ext3, and not
'upgrade' them to ext4.

There are two upgrade paths to 10.04 LTS: from 8.04, and from 9.10. If
it were me, I'd deploy with 9.10, and upgrade from there when 10.04
comes out.

Why? I don't have a scientific reason for it, but a step from 9.10 to
10.04 will be more 'incremental' than from 8.04 to 10.04. Take ext4 for
example. 9.10 uses ext4 by default, so there will be no worries there.

Re: [SLUG] Ubuntu Server LTS

[david]

I'm using Ubuntu Hardy on servers (one mail, one web/database/dns of mine, plus one fileserver run 
by my son-in-law) and we have not found the need to upgrade. I'm waiting for the next LTS.


I don't think this is viable on desktop but on server I think it's more than desirable. If it ain't 
broke, don't fix it.


A little bird told me that the latest Ubuntu does ext4 by default (is this so? should you care?) so 
that may be a factor for you. Changing filesystems is probably something you would rather avoid.


Ironically, I started using Ubuntu because I like the Debian paradigm but didn't want to wait so 
long for upgrades! Except for the PulseAudio debacle (see previous thread) I have had no real reason 
to dislike Ubuntu. Naturally PulseAudio doesn't relate to servers.


OTOH, I haven't used Redhat since V.7 so maybe it's much better than Debian now.. who knows? It 
strikes me that Distros are like modern cars.. they all work pretty well and they are all pretty 
reliable, but that's just an impression I have.

Re: [SLUG] Ubuntu friendly 12' netbook

[Dean Hamstead]

I would certainly not consider running gentoo or freebsd and rebuilding 
world.


However my aspire one serves as a very chep, v small, v quiet and low 
power dhcp/dns/monitoring server. Add one usb2ps2 converter, and one 
connection to a kvm or an ssh connection, and its crapped keyboard is no 
longer a problem :)

Re: [SLUG] Ubuntu friendly 12' netbook

[Dean Hamstead]

I have a ~$1000 acer laptop and an acer aspire one.

The former is utter garbage, the later is really nice.

I suspect this aspire one goodness, rests mainly on an intel developed 
reference board which has had minimal customization. The cheapy one has

all sorts of strange quirks.

The sluggishness is almost certainly related to the video driver performance
regression in Ubuntu 9.04. There are some half-fixes which introduce new
problems, but for most users I recommend going back to 8.10 for now. Easiest
way around it, sadly.

Your audio issue I'm not so sure about (Skype works okay here whether I have
pulseaudio running or not, so, hrm).

Thanks everyone, I'll go with that.

Reason I still use Gutsy is that the visor module (for Palm/JPilot)
appears to have broken after Gutsy. Admittedly I spent about 3
nanoseconds troubleshooting it and really should try to solve the
problem or lodge a proper bug report... (Reminds me of the story given in
management classes about the guy too busy chopping down a tree to stop
for 5 minutes and sharpen his axe so he can chop the tree down faster).

You can use

All the old releases are archived there all the way back to warty if
you're that desparate :)

But as Marty said I'd also recommend moving to Hardy.

as https://help.ubuntu.com/ notes, gutsy is no longer receiving security
updates - or any changes at all.

Given the continual stream of security updates I see for my machines, I
really encourage you to upgrade. I suggest that hardy, a
long-term-support release is probably easiest and best - it will stay
supported for quite some time.

Re: [SLUG] Ubuntu, Network Manager, USB 3G, ZTE Support, How to Help?

[Tom Deckert]

Thanks to Sridhar - I have posted that information to 
the support forum.

Glen's post is great information.  As I understand it,
I need to set up a udev rule to load the proper productID,
and an XML HAL entry to ensure NetworkManager gets notified
when the device is plugged in.  After that, I'm hoping 
NetworkManager "just works" and connects me.  (I'm hoping
it isn't fatal that I/NM do not know the NMEA 'sentences'.)
  
Thanks,
Tom

Re: [SLUG] Ubuntu, Network Manager, USB 3G, ZTE Support, How to Help?

[Glen Turner]

Tom Deckert wrote:

Hi,

The 3G USBModem I purchase does not work when I plug it
in to Ubuntu Intrepid Ibex.  I want it to "just work".
I emailed here, and Ubuntu Forums, and then finally thought 
to contact the manufacturer, ZTE.


I told them adding Linux support would be easy, all they needed
to do was provide information about their devices to the Linux
community.

On their support forum, they responded: "What information do you need?"


So, what information do I need?  To whom do I need to provide it?
I know:

Model: MF626

VendorID = 0x19d2
ProductID = 0x2000  (Storage) 
ProductID = 0x0031  (modem)


A person at the ZTE forums reported the Device Map:

DIAG VID=0x19D2,PID=0x0031 MI=00
NMEA VID=0x19D2,PID=0x0031 MI=01
TCard VID=0x19D2,PID=0x0031 MI=02
Modem VID=0x19D2,PID=0x0031 MI=03

The modem commands are:
AT+ZOPRT=5 - makes the device to stay in online mode
AT+ZCDRUN=8 - disables auto-run
AT+CGDCONT - configures the correct APN profile


These devices look like a modem to Linux. Like a modem
you issue AT commands and use PPP to establish the Internet
link.

That's an illusion of course, since the PPP connection
terminates on the card itself, and the card communicates
with the telco infrastructure using another set of protocols.

You can get a view of that world from the DIAG port, and the
protocol for that port is vendor-specific.  Usefully, the DIAG
port will cough up received signal strength information.

The NMEA port is a USB serial device view of an artificial
NMEA device (NMEA is the serial protocol used to network
boat electronics). The NMEA protocol could be used to access
the timing signal of the GSM protocol, or there might be a
full GPS receiver in the USB stick.  You'll need to ask, and
you'll need specs on what NMEA "sentences" activate which
features.

The Tcard is your USB storage device. Typically manufacturers are including
these to give distributors a simple way to distribute their driver
software with the device.  I've only ever seen one device where this
also held the firmware for the device -- more typically the firmware
is upgraded through the DIAG port.



I'm not sure who's job it is to figure out that when a
MF626 is plugged in, it should ignore the USB Mass Storage
and just set up the modem to run.


You want all of the on-board devices to come up: you just
need to push the IDs into the USB serial driver (there's
module options if you want to experiment prior to coding).

For the modem and NMEA serial devices you want the features
and the AT commands or NMEA sentences to use those features.
Sierra Wireless gives these out in their manuals, and they
are a nice example to provide your manufacturer.


Question:  Should I file A) HAL bug report,  B)NetworkManager
bug report,  C) HAL and NetworkManager bug reports?
D) Something else?


If the serial driver doesn't automatically load, then it needs
IDs added, and this involves udev.

If it does load then it's up to HAL to organise the correct
user-space response. For the GSM modem that's sending a
D-Bus message with the serial device ID, which Network
Manager receives.  Later NM understands GSM modems.
Although that sounds a lot of work, copying the XML
HAL configuration from another GSM modem is simple.

As you can see, udev and HAL duplicate some functions,
and there's a move to combine the two.

For the NMEA device, HAL doesn't understand these at all.
Which is a shame, as there's a growing need for applications
to share info from location and time devices.  Without
developing all that, ensuring udev loads the USB serial
driver and you can see the sentences in a terminal emulator
is about all which can be done.

The DIAG port will need a driver.  From what I've seen to
date, this can be a trivial module layered over USB serial.

The storage works, as it should. Would be worthwhile seeing
if there's a HAL option to hint to the desktop system not
to bring this device to the user's immediate attention
(ie, create desktop icon, but don't open the file manager).
