I agree with you in principle.
But it is very difficult to pin down a problem that only arises
from time to time.
In my experience NM starts on this laptop about 60% of the time,
after one re-boot about 25% of the time,as 
and after two re-boots about 10% of the time.


I don't find anything that helps except a complete reboot.
I wish I could get NM connecting before login;
then I could tell if it wasn't working,
and start again in that case.

My experience is that the checkbox for enabling at boot time is there for a 
reason, unfortunately the reason doesn't seem to be so that the network will 
actually be connected before login. I have it checked but the light on the USB 
WiFi doesn't even blink until I log in, at which point it suddenly negotiates a 
connection.


And if you need to use it remotely, better just write a script, if there's a way 
to tell it to connect to the AP *first* then start the VPN to the home office, I 
haven't found it, and of course writing usable documentation, as Mathew says "is 
not a good use of developer time." Which is a polite way of saying that "if it 
was hard to write it should be hard to use."

Not so.
I use Linux (Fedora and Centos) 95% of the time, by choice.

But I find your instinctive denigration of Windows
just as annoying as the opposite denigration of Linux.

I think that any reasonably objective person will agree
that many things are done better in Fedora,
and many things (eg WiFi) are done better in Windows.

I just hope that Linux developers look at Windows with open eyes,
and imitate what Windows does better
(and do not imitate what it does worse).

> For a lot of people Fedora does work without needing twiddling,

I can't believe there is a single such person, let alone lots of them.

One need only say "KDE 3 to 4" to realize how unlikely it is
that anyone could use Fedora with no "twiddling" at all.
Is there anyone in the world who has found Fedora
sound and multimedia worked first time without any "twiddling"?

In my experience, Windows screws up far less often than Fedora.
But when it does screw up the problem is usually insoluble,
at least by me.
I have absolutely no idea why my Asus Athlon64 machine
re-boots endlessly in Windows XP Home,
but works faultlessly under Fedora-10.

I have similar feelings.  I view being asked to fix up someone else's
computer with the same amount of enthusiasm as if I'd been asked to
unblock their toilet with my bare hands.

I don't know why people who're really uninterested in computers want
one, much less why those who're useless with them continue at it.  I

practising it.

Make a computer that an idiot can use, and idiots will use it (and then
they'll cause merry hell for everyone else).  Oh, hang on, Microsoft's
already catering for that demographic, and all the viruses, scams, etc,
spread about by computer morons have made life hell for everyone.  You
have a Fisher Price interface, and limited functionality in an expensive
gadget that should really have nearly unlimited capability, yet it's a
Pandora's box that's all too easily exploited to spread its evils unto
all and sundry (viruses, owned boxes of zombies, and commercial
crapware).

It's a "magic box".  Some people (including some that I have to
regularly deal with), think that putting a computer in will solve all
their problems.  Problems that they don't understand in the first place,
never mind trying to understand a computer, as well, to manage their
situation.

Do you see what I mean?  There is no end.

Fedora is open ended, as are most Linux distributions. 

Windows and OSX, on the other hand, are closed systems, meaning that if 
you cannot buy a program to do what you want, your computer cannot do it.


Sure, you can buy a compiler and write your own, but what if that nifty 
app that you do buy is almost perfect?  You are stuck.


With every app in the Fedora repos, you have access to the source!  Is 
it almost perfect?  Fix it and submit your modifications upstream.


But here we are again at that barrier of technical ability.  And that

Use what you are given, or become technical.

I'm afraid you are viewing Fedora with rose-tinted spectacles.

Just consider WiFi, which is what this thread is nominally about.
Under Windows there is a straightforward and intelligible route
to setting up a WiFi connection -
one clicks on "Connect to" and "View all connections"
(I may have the titles wrong)
and then right-clicks on the WiFi icon,
and follows instructions.

In my experience this works 98% of the time,
and if it does not work I give up and use a different machine,
or try to get an ethernet connection.
I probably do not try to read up on the matter,
as experience tells me this is unlikely to be rewarding
on a Windows system;
while if I follows the Troubleshooter I am almost certain
to find myself in a circular loop.

If I don't have a driver for the WiFi device I am using
this is fairly obvious, and getting an appropriate driver
and installing it is fairly straightfoward.

Under Fedora, NM works eventually for me
about 95% of the time,
after an average of 1.4 re-boots.

The point is, when I ask about this
I get an enormous amount of information,
among which is probably the nugget I need.
But the process involves investigation and mild research.

This is not necessarily a criticism of Fedora (or Linux).
It is simply a description of the difference from Windows.

I think one should be honest and tell anyone
thinking of using Fedora that they are going to have to
spend quite a lot of time and energy getting it
to do what they want, whether connect to WiFi
or listen to music.

The suggestion that they will be able to solve their problems
by posting log files to "technicians" is laughably inaccurate.

Unfortunately, I don't think Fedora - which I explicitly mentioned -
is a good OS to recommend to someone who just wants a system to work.
I wish it were, but you would have to be blind to reality to believe it is.

I think someone who just wanted a system that works,
and wasn't willing to experiment and read about the system,
would find Fedora very frustrating.

But I was replying to a poster who said, in effect,
that "ordinary users" should not bother with logs
but should just send them to "technicians" if they had a problem.

My view is that logs should be intelligible to the interested user,
and developers should make some effort to make them intelligible,
in particular by documenting what they mean (eg in NM)
by "state2 -> state 3", etc.

I don't really understand the attitude of the NM developers
to documentation.
I would have thought anyone who had put in that much time
in developing an application would want to explain to people
how best to use it.

> So, I really should tell my 86yr old dad to stop using Linux?

It's not a matter of age, it's a matter of attitude and temperament.
Many 80-year olds are eager to learn.
Many 20-year olds only want to get from A to B.

When did I say you shouldn't learn?  Look at the message /you just
quoted/.  I said if you "don't want to look them up" or do anything else
productive, you should stop complaining.  Nowhere did I suggest you take
an apathetic approach, or ignore everything and send it to tech support.
 In fact what I recommend is that you take initiative for your own
system and learn what you can about it.  However, I would not claim that
I can figure out everything without seeking help either.

Mine takes quite some time finding my dlink DIR-300 access point (around
twenty seconds), and a little bit longer logging on (around ten to
fifteen seconds), it's not the same each time (sometimes it takes ages,
sometimes even requiring restarting NetworkManager, but I suspect that's
down to NetworkManager or the wireless interface not waking up well
after the laptop was suspended).  It finds the neighbours, much weaker
signal strength, access points almost immediately (some encrypted, some
open).  I don't know what brands they have, I've never asked them.

My access point is set to announce itself, and the polling interval is
fractions of seconds, so I expect it to be quick to find, though it's
not.

Thanks for the compliment. I'm not related to Emory. I'm just a simple
technician.

I've been on the Fedora list for a long while and expect to remain on
it. I've been somewhat undiplomatic at times but I eventually learned to
shy away from flame wars and not get involved. The real satisfaction for
me is often the learning process I go through when implementing the
advice I'm given here by others, and I finish feeling one step  closer
to having expertise.

I agree that whatever a process can send to a system log, for purposes
of error output, the better. If a URL could be supplied by a log message
pointing to a resource that can help explain the meaning of the exact
error code, that would be a great help too, because it saves the
technician's time in tracking down the error.

Speaking as someone who fixes other people's computers for money,  I
wish that "regular users" of every flavor would get accustomed to
looking at log messages. Or at least email them to me on request. Doing
so could save both of us a lot of time and money. I wouldn't have to
charge so much, and my time is conserved for focusing on the really
tough issues.

I don't really draw any line between a "regular user" and someone with
perhaps additional skills or training. In real life, working with real
customers, I've seen a lot of variation here. Some customers have great
technical skills,  some don't. Some have a lot of smarts and can be
coached to find and email a resource to me. Some are driven by time
constraints that have to be appreciated and understood by technicians
like me. Most are a lot smarter than they seem. What they have in common
is a problem they all want fixed quickly and quietly. If that person can
sift through log messages, and email them to me it helps a lot.

So the more log output pertinent to an error, the better.

By the way my Network Manager implementation works okay with my wireless
hardware. I've discovered that it needs an amazingly long time to build
a connection to the access point -- I think there is some sort of timing
issue with it. But generally within 3-5 minutes of my logging on to my
user account, the machine does connect to the access point. I just get a
few more gray hairs waiting for this to happen.

That's another valid option, if you really think the logs are harming
your performance (the impact is usually negligible for desktop machines
and small-scale servers).  Otherwise, just ignore them.

If you never want to see the error messages, then turn off sending
them to the log files. You can configure (r)syslog to throw them
away. I like the fact that I can go digging in the logs when

That's a ridiculous statement. /var/log/messages is not something
regular users are supposed to be looking at constantly.  In normal use,
messages get printed there and ignored.  That's okay.

However, when an error occurs, it is vital the user be able to go to the
logs and copy relevant information.  Having a "enable output to
/var/log" option would make it very hard to find intermittent errors.

If you're an ordinary user and don't plan to file a bug report, just
ignore the logs and go on your way.

What you and Mikkel say make me realize I'm the one who is the dummy
here. I was assuming that NetWorkManager will automatically connect to
my hidden wireless network after I did the setup work after choosing
System --> Administration --> Network, and supplying my network details.
Maybe that GUI has nothing to do with NetworkManager. But I didn't think
of this at the time. I saved the settings in that GUI, got a message
indicating I may want to restart my network, and without thinking that
the 'network' service is turned off in chkconfig for all runlevels
anyhow, I merrily typed away 'service network restart'. Ouch.

It looks like I have to click the gui icon on the top right of my
desktop showing two computer monitors and then select either a visible
network name, or 'Connect to hidden network...' for the first time one
does a wireless connection. I'll reboot soon to see if it connects
automatically from here on.

Apparently there is a settings file in
/etc/NetworkManager/nm-system-settings.conf that one can work with, but
mine only has the text

[main]
plugins=ifcfg-fedora

and there seems very little NetworkManager documentation to start with.
Maybe it is all in the wiki.

This is only true if you don't have a systemwide configuration set up. The
current NetworkManager can also use configuration from
system-config-network, just as the old network service does.

Part of the problem here is understanding the difference between the
network service and the NetworkManager service. The network service
will connect before you log in, while the NetworkManager service
connects after you log in. You normally want to run only one of
these services. I like the network service for servers and desktops,
and the NetworkManager service for laptops. (I need to be able to
connect to my desktop even if nobody is logged in.) You can have
both services running at the same time, but you have to make sure
you have the interfaces that you do not want NetworkManager to

Re: NM: the usual rant

2009-03-01 Thread Robert L Cochran
I too am having a problem with Network Manager, and like Anne, I should
file a bug and provide feedback if requested. In my case Network Manager
seems to have a terribly difficult time connecting to my wireless
network before I login. I always have to force a restart of the network
service in order to get the magic "Connection Established" gui popup
message and the connectivity bars icon showing at the top right of my
screen. I think it may have something to do with a problem in ifup-eth
and dhclient.

[r...@deafeng3 ~]# service network restart

(At this point, if I see the line about ifup-eth, the "Connection

regardless of the failure messages mentioned above.)

Maybe I ought to be using a different kernel driver...

I agree with you in principle.
But it is very difficult to pin down a problem that only arises
from time to time.
In my experience NM starts on this laptop about 60% of the time,
after one re-boot about 25% of the time,
and after two re-boots about 10% of the time.

I don't find anything that helps except a complete reboot.
I wish I could get NM connecting before login;
then I could tell if it wasn't working,
and start again in that case.

I probably shouldn't have said "error message".

Surely it would take very little effort to explain what

My impression is that NM does not wait long enough at some point,
which if true could be reported in normal English.

In the good old days one could understand why They said "error 478",
because space was so short.
Nowadays everyone has acres of space.
Even if the kernel error messages are kept secret,
I think the NM messages, "stage 6 -> stage 7", etc,
could be made intelligible with very few extra bytes.
Eg "Contacted dhcp server. Response: unknown device."
This would at least suggest where to look.

Oh there is no doubt of that. I downloaded the source for gdm
to try and understand how I might fix bug 451562, and it boggles
the mind. An app who's one job is to validate a user and let
him login has become a vast series of interlocking dbus connected
apps, shuffling around information like some con artist running
a shell game.

If I were to try for years, I couldn't manage to make such a

If you want to look at poor practice then gdm is a far better example -
that *used* to be a usable piece of software then it got "improved" and
nobody bothered to finish the job and make the UI configurable or remote
management configurable by mere mortals.

Network Manager at least goes in a forward direction but horribly slowly
- especially considering the Nokia maemo devices shipped with equivalent
  functionality to that aspired to by NM and has done so for years now.

Didn't I agree NM was a nightmare?  But your problem is not NM.  Your
problem is you don't have a realistic view of software development
practices.

Hmm - I had a problem with NM.  I reported it.  I gave feedback as and when 
requested.  The problem is solved.  I'm not complaining :-)

It's not "completely non-functional" for everybody. I for one have no
problems with it (DHCP and wired LAN, one of the simplest cases of
course). Hyperbole just alienates people and doesn't help get it fixed.

What you're seeing are bugs in the _driver_, not in NM!

Too bad the NM developers didn't feel like doing that
to fix the problems with network instead of deciding
to just chuck everything and write a completely
non-functional incompatible "replacement".

No, it's not.  Note that I didn't say, "Email the error codes the
developers personally."  File a /thorough/ bug report on a bug tracker
or developer mailing list, or ask for advice from users, such as here.

You're a fool.  What do you think this magical commercial support does
when confronted with a problem?They read the source and developer
documentation and solve the problem themselves, or they report a bug
once they have enough information.

Exactly the same thing you could do if you weren't busy whining.

Yes, it is a far better use of developer time to be inundated
by folks asking what the hell obscure messages and behaviour means.
But, not to worry, it won't be the actual NM developers
who get that grief, but instead the poor fools who
offer commercial linux support.

It's probably a bug in your network (wireless?) driver rather than NM. What
driver are you using?

A kernel error code.

There's an enum somewhere in the kernel.

Another kernel error code.

They're intended solely for driver developers, there's nothing you can do
about these errors anyway if you're not a kernel driver developer. Just
file a bug against the network driver you're using.

Some are for end users, some are for gurus (meant for posting on bug
reports and mailing lists).  "Translating" every error message is not a
good use of developer time.

Use The Source, or be patient.

True.
