RE: youtube-dl

[Carruth, Rusty]

First, unless you update your packages list (if using synaptic its 'reload db' 
or something) you will NEVER know if a newer package is out there.

 

Second, I use those firefox (and mumble mumble (seamonkey? And other)) browser 
plugins.  DTA (down them all), ant, and something else.  They've worked fine 
for me..

 

Third, 2006 seems REALLY old for something like this.  Indeed, if you go to 
http://rg3.github.com/youtube-dl/ you'll see in the download section 
2012.10.09. (which is also the only version, which seems mildly incongruous. Of 
course, the thing you download seems to be a binary file interpreted by python, 
which launches me into a 'huh?  Gotta go figure THAT out sometime' mode ;-)

Mine shows the same copyright test although the package I got this am from the 
ubuntu software center installed 
/var/cache/apt/archives/youtube-dl_2012.02.27-1_all.deb.  I get the same result 
as Michael although I can certainly play the video directly from the link 
included in the command line.

Mike, most programs have an option to display the version.  According to the 
youtube-dl man page it should be -v but it does not work.  It reacts as if you 
have provided wrong or insufficient parameters.  I would say maybe look for a 
different package to download youtube videos which have better or more uptodate 
maintenance.  Another option is to volunteer to help with the maintenance 
and/or documentation.

RE: Spam control? (was RE: virus)

[Carruth, Rusty]

As I remember (but remember whose memory we are talking about :-) -

I had 3 lists - those known to be spammers, those known to be ok, and
anybody else.  (Ok, so the 'anybody else' wasn't actually a LIST, it was
anybody not in the first 2 lists)

Known spammers got some huge delay (I think I finally ended up with 24
hours!), known safe senders got zero delay, and unknown got a few
seconds (or maybe I made it zero, I don't remember).

So non spammers got either zero or minimal delay.

If I can remember, I'll see if I still have that config file somewhere,
cause now you got me curious!

I should mention that there IS one 'small' downside - if you get ALL
your internet sockets tied up with spammers then you cannot receive (or
send) email (or do anything else network-related until one of the
sockets frees up).  I don't think I ever hit that limit, but then I only
do email for my family...

Spam control? (was RE: virus)

[Carruth, Rusty]

Some time back I thought the best solution would be to form a co-op.  Members 
of the co-op would run some sort of program to detect spammers, and then join 
together in a DOS attack on the spammer's MTA.  Detection should be pretty 
easy, I'd think, with minimal false positives.

When I thought of that, it wasn't illegal.  It is now, so I've dropped thinking 
about it, but it would have reduced the spam.  Of course, the collateral damage 
(to clueless users whose machines had been 0wn3d, as a minimum) would have been 
pretty high, and I'm not sure they would have been able to figure out why their 
systems broke down.  Probably would have required a pretty big education 
program, as it were, to get people to either (1) stop using the primary virus 
propagator of the universe (I am, of course, referring to a certain operating 
system); (2) get off the internet; or, (3) keep their virus scanners up to 
date.  Assuming, of course, that most spam comes from 0wn3d machines.  Not sure 
that's a valid assumption.

I've tried running that thing that keeps spammers busy trying to deliver the 
email (tarpit?  I cannot remember - the idea is you keep telling unknown MTAs 
'hold on a moment' for a while - say an hour or more, thus keeping their 
delivery rate low.  I should mention that at home I run my own MTA, so it was 
an option for me.  Anybody using their ISP's MTA (or gmail, or...) cannot do 
this).  The problem is that you need a LOT of people running that for it to do 
much good in spam reduction overall, and I don't' know if it reduced mine (but 
it was satisfying to look at the headers and see that couple of hour delay).  

I finally gave up and just kept changing my email address (and I also used the 
spam detector in my email program).

Subject: Bash script with env variables

 

Hello all,

I was not sure how to google this, so any pointers is appreciated.

 

I have a file, $FILELIST with an absolute file path on every line, with the 
caveat that the first portion of the path is an environment variable. For 
example:

 

$PROJ_ROOT/path/to/file.txt

$PROJ_ROOT/path/to/another/file.txt

 

My script looks like this:

 

for file in  `cat $FILELIST`

do

if [ -f $file ]

then

echo "Copying $file"

cp -f `echo $file` $DEST/.

else

echo "file not found: $file"

fi

done

 

The problem is that the $file is not evaluated to the path. I just get 
"$PROJ_ROOT/path/to/file.txt' not found.

 

If I copy the text and run "more $PROJ_ROOT/path/to/file.txt" I see it just 
fine.

 

How do I get Bash to evaluate the $PROJ_ROOT env variable for the -f $file?

Thanks,

Eric

RE: why /var/log/messages went crazy?

[Carruth, Rusty]

I will guess that this is just as you were shutting down, so the avahi daemon 
shutdown is 'normal'.

So, it looks to me like something is funny with acpi.  Have you google'd for 
all or part of the error message?  Did you add or remove some hardware between 
the time it always worked fine and the time it started to die?  I forget it you 
upgraded between those points - please remind us.

I don't know enough about ACPI to know what to suggest, and if turning it off 
is semi-irrevocable (if not, i'd try turning it off and see if the system stays 
'non-spewing' for a 'long time' (relative to past experiences).

Just a few thunks

Subject: why /var/log/messages went crazy? 
 
Several days ago, my /var/log/messages (and syslog and user.log) went
crazy adding entries so fast that my system crashed due to the root
partition filling up and giving a "no space left" message.

Thanks to help from plug and another forum, I was able to delete enough
files to regain enough file space to get the system restarted, and I then
flushed the overloaded error message files and for several days, no
messages were added in /var/log/messages , syslog, and user.log for about
a week. I was checking for new messages every day or two and all seemed to
be okay until today, something caused the /var/log/messages and syslog
files to start filling up rapidly again.  This time I saved 1,000 of the
most recent entries in the messages file (several thousand messages were
added today), shut the system down, and rebooted.  After that, the
messages and syslog files slowed down to a trickle ... but how can I
figure out what is causing a flare-up like this?

I've posted the last 1,000 entries at this link:
http://www.upquick.com/temp/messages.last1000

As you can see, messages were being added at a rate of 15 to 20 per second
before I shut the system down.  After reboot, messages were only added
every couple of minutes or so.

Can anyone please tell me what might be causing these message flare-ups
and how to stop it.

Did you tell synaptic to update.. oh, sorry, 'Reload'... its database
first?  Please try that and then try the download of permagic.  In fact,
I can almost guarantee you that will fix it, as I just tried to download
perlmagic using synaptic, and it failed.  THEN I did 'Reload' and tried
again, and viola', it worked.  (You may also then have to update qt4,
but oh, well J)

 

(BTW, I said default 'route' (I hope!), not 'root'.  Say 'route ' to see
if you have a default one. ;-)  It is likely that you do, since you can
do web browsing and email (and since the pings worked), but just wanted
to clarify that.  Since ping worked, you can skip the 'check your
default route' step :-)

Lets diagnose your network connection and other random things first:

 

Are you connected to the internet?  Why do you give the answer you give?
("Because web browsing (works/fails)", etc)  If web browsing works, does
it have a proxy set up?  If so, is the proxy set up system-wide or just

Do you have a default route?

 

What happens when you say 'ping inficad.com'?  How about ''?

 

What does 'traceroute -n archive.ubuntu.com' say?

 

Also, let's look at apt. have you used synaptic (it's a gui over apt-get
and friends)?  Try that, tell it to update the files list, select
perlmagick to install, say 'apply', and see what happens.

 

Also, what version of ubuntu are you using (ok, I see its precise, but I
don't remember the mapping from name to number, sorry)?  If its
unsupported you won't find any packages - you'll have to fix your
repositories...

RE: perlmagick

[Carruth, Rusty]

First, if you cannot download stuff using apt-get, you first need to
find out why, or you need to use your web browser to manually download
all the files it wants...

 

Lets diagnose your network connection and other random things first:

 

Are you connected to the internet?  Why do you give the answer you give?
("Because web browsing (works/fails)", etc)  If web browsing works, does
it have a proxy set up?  If so, is the proxy set up system-wide or just
for the web browser?

 

Do you have a default route?

 

What happens when you say 'ping inficad.com'?  How about 'ping
archive.ubuntu.com'?

 

What does 'traceroute -n archive.ubuntu.com' say?

 

Also, let's look at apt. have you used synaptic (it's a gui over apt-get
and friends)?  Try that, tell it to update the files list, select
perlmagick to install, say 'apply', and see what happens.

 

Also, what version of ubuntu are you using (ok, I see its precise, but I
don't remember the mapping from name to number, sorry)?  If its
unsupported you won't find any packages - you'll have to fix your
repositories...

 

Just a few random and wild guesses...

RE: System crash - now shows "no space on device"

[Carruth, Rusty]

I don't know if this will fix your running out of space issue (mine is
usually a disk drive spewing error messages at a VERY high rate of speed
- like gigabytes of messages per hour), but:

Your SNMP (simple network management protocol) daemon is complaining
about something - a lot (Google is your friend, probably)

That message from klogd about ACPI is disconcerting, I'd search Google
about that even though there aren't that many entries in the log about
it.

In any case, get SNMP to stop complaining and your log will be smaller.


IMHO, Adding 682 entries upon bootup is nothing to worry about, really
(unless you boot every few hours :-) - in which case I'd say don't boot
every few hours :-)) - it's the ones that keep on coming that eat up
space.

RE: System crash - now shows "no space on device"

[Carruth, Rusty]

Unfortunately, once you've deleted /var/log/messages and /var/log/syslog (and 
/var/log/kern*) any chance of knowing what happened is probably lost, because 
those logs contained the spewing that was either the cause of the failure, or 
the information about the failure. 

Next time I would advise booting on a standalone boot cd and taking a look at 
the log files above to see if it's something that you're going to need to 
'worry about' (like a disk drive going bad).  Just for 'grins' you might want 
to check the 'S.M.A.R.T.' information to see if your drive is getting tired.

(Disclaimer - I did not read the entire thread, someone may have already said 
all this.  Sorry!)

Side note - why some variants of Linux have messages, syslog, and kern.log when 
they are ALMOST identical (and when things 'go bad' take 3x the disk space), 
I'm not sure.  I have noticed that Linux Mint only has syslog and not messages 
(haven't checked for kern)...  It may be possible to tune the assignemt of 
messages to files such that you minimize the duplication, but I've not felt the 
need to (even though there have been more than a few times that a disk drive 
'going bad' has filled up the root partition here at work).

And yet another 'by the way' - this whole 'running out of space in /var' thing 
is why some people put /var into its own partition.

RE: text file needs a carriage return

[Carruth, Rusty]

If you want a script to enter data from inside the script as if you had
typed it, you use the '<<' input redirect like so:

 

#!/bin/bash

echo Put stuff into a_file:

cat << EOFEOF > a_file

This line goes in to the file

So does this

This does too, but the next line tells the shell to stop reading and
give an EOF to 'cat' so it will stop.  

EOFEOF

echo This is the next line of the script to execute.

 

Execution of this script results in 'a_file' having 3 lines, and your
screen would look like this:

 

~> ./my_Script

Put stuff into a_file:

This is the next line of the script to execute.

~> 

 

Typing ^C or an actual control-c in the file would not work, I think.

wait a second... I don't need a carriage return  but rather cntrl-c.
would typing '^C' have the desired effect?

Then the script would look like:

  cd linux-3.2.6

  make mrproper

  make headers_check

  make INSTALL_HDR_PATH=dest headers_install

  find dest/include \( -name .install -o -name ..install.cmd \) -delete

  cp -rv dest/include/* /usr/include

  ^C

  .  2>1|tee 

 

But I still need the carriage return symbol so I can enter the script
and then:

 

  cat | grep  uh. what text appears in errors in this
case?

so I can find errors before I move on to the next tar file w/o hiting

RE: dhcp question.

[Carruth, Rusty]

I just searched the canon site, and I could not find any way that that crazy 
printer could be set for static IP address!

Good GRIEF!  How stupid!  Yet another reason to avoid Canon like the plague!  
(Or at least I've had bad luck with canon printers, so they are not on my 
'first to consider' list.  Indeed, they are on my 'last to consider' list.  I'm 
appreciating my Epson more every day!).

I think you're toast.  You'll either need to set up a DHCP server that WILL 
allow you to set a 'fixed' IP address to a MAC address, or you'll have to get a 
different printer, or (if the thing has USB like one manual said) you'll have 
to hook it up via USB.

Sorry!  Maybe someone else can give you a more hopeful suggestion, but I'm 
fresh out.

RE: dhcp question.

[Carruth, Rusty]

Looks like the DHCP server doesn't do staically-assigned dynamic addresses (it 
only SOUNDS like an oxymoron!).

So, you need to tell your printer to have a static ip address.  Go to the 
printer and set it up with an ip address not inside the DHCP range your DHCP 
server gives out.

I've not looked at the logs, but you may need to try more than an IPP protocol. 
 Also try this:

http://www.usa.canon.com/cusa/sna/consumer/printers_multifunction/pixma_mx_series/pixma_mx439?selectedName=DriversAndSoftware

and select linux as your os, see if that gets you anywhere.

This should've been sent to the list, not just to me.  The list can solve
problems in parallel, while one person can only solve them serially.  I'm also
not a printer guru; the last time I had a printer at home was 2006.

Neither of those is what you actually need to assign that MAC to a static IP
addr.  I'm not sure, but that router may not actually have that capability. 
No real worries though.

Yikes, that's a lot of text.  

> printer-uri = "ipp://192.168.0.68:631/ipp/printer"'

This shows that CUPS got the right IP address for the printer and is trying to
talk to it on port 631 using IPP.  CUPS thinks that the job was submitted
successfully, as in "[Job 278] Set job-printer-state-message to "Print file
accepted - job ID 1."  It thinks the job was completed successfully too.

Lines 685..694 in the logfile show things complaining about color profiles. 
I'm not sure what this is about, or whether it's worth looking at.

> It is terribly frustrating that something like this should be so
> enormously complicated.

Canon has never been terribly Linux-friendly.  When buying hardware for a
Linux system, the *first* thing to do is do some research on the Net.  If you
can't find one or two reports of "I bought a FOO-1234 and got it working with
Linux pretty quickly, here's what I did!" then buying a FOO-1234 for use with
a Linux system is *not* a good idea unless you're experienced.

Printer trouble has been with us for a very long time.  (What inspired Richard
Stallman to get serious about Free Software?  A recalcitrant printer)

RE: how to transfer files

[Carruth, Rusty]

First, you need a way to know your dynamic ip.  DYNDNS is probably what
you want there.  Or scripts on your home machine to email you whenever
the ip address changes, or something.  (google for dynamic dns:
http://www.google.com/url?sa=t&rct=j&q=dynamic%20dns&source=web&cd=1&ved
=0CF8QFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FDynamic_DNS&ei=E9o
qUNSwJKazigKx44CoDg&usg=AFQjCNHmZFYaxBiTegkz4DtZfZ87o2OGgg&cad=rja AS AN
EXAMPLE)


Then, ssh or scp to the machine, assuming you allow those ports to the
world, which probably is not a great idea.  Others can surely give a
more secure approach!

RE: print from computer attached to another computer

[Carruth, Rusty]

Tell the computer with the printer to share the printer to other
computers (system/administration/printing then right-click on the
printer and make sure 'shared' is selected)

Then tell the computer without the printer to find a network printer, or
maybe you'll have to give the IP address of the first computer, I
forget.  (ISTR that it was almost trivial, once the server knew to share
the printer).

speakeasy/megapath (was RE: CenturyLink/DirectTV)

[Carruth, Rusty]

I use what used to be Speakeasy, now is megapath (bought out).

I was VERY happy with Speakeasy - you call their tech line, they are
TECHNICAL folks.  I could talk routers, NAT, whatever with them and they
knew it.

I have what I call the 'sysadmin at home' DSL package - 2 static IP
addresses, telnet access to a server there on their site, almost all
ports open, and 'minimal' tech support for $60 a month (I think I'm at
2.5Mb/s down, but I'd have to look - a while back they did a 'free'
upgrade from the 1.4 or whatever that I had before that).

I end up calling them for something about once a year - usually because
I forgot a password.  Last week I had to call them because I was
installing a new firewall and the hard drive of the previous one died so
I had no idea of my static IP addresses OR my default route! (oops) They
weren't quite as quick and techy as I remembered, but then all they had
to do was look up my static ip addresses and default gw, so it really
didn't matter.

I run mail server at home (which is why I chose them), I have run a web
server there (plan to set it back up 'real soon now' :-) ), both with no
issues.

However, you guys talking about 'outages' make me go - huh?  Outage?
I'm sure we've had some, but I haven't seen anything but the periodic
lockup of my DSL modem such that I have to power cycle it (no more than
once a month - in fact the last time I did that was probably 4 months
ago) - and I'm not sure I can blame them for that (it's my own modem -
previous one died and I just threw my own in there).  Well, ok I
remember there have been scheduled outages at times, but their scheduled
maintenance is almost always between midnight and 6am, as far as I
remember, so I don't remember ever being offline due to them.  I may
have been, but I don't remember it...)

Overall I've been very happy with them.  But then I've not had to really
deal with them since the MegaPath switch.

RE: Laptop Battery Life

[Carruth, Rusty]

Warning - what you are about to read is from the "king of rechargeable
battery killers", so take it with a few metric tons of salt!

 

I have recently been told that, for newer-technology batteries:

 

1 - you do not want to overcharge them - a sure killer

2 - charging to 100% all the time risks overcharging.  Charge to 90-98%
instead.

3 - discharging to some point below 20% reduces battery life, avoid it.
(I'm not sure what the lower bound is)

 

However, I have also been told:

 

A - always fully a discharge new battery and recharge fully 3 times
before use - this is supposed to make batteries more prepared or
something.

Vs

B - never fully discharge a battery.

 

Do we have anyone who works in the battery industry who can give us some
real insight?

Both are taking a charge.  After they are fully charged I will put them

I've have had poor performance from laptop batteries and did not want to

RE: g++

[Carruth, Rusty]

Call me a , but I like the kitchen sink editor.  Which is to
say 'emacs'.  You can even use it as something of an IDE, if you wish.
(And it has syntax highlighting, all that sort of stuff).  To compile,
just 'Macro-x compile' (IIRC, and I think I do), then you can visit each
error/warning, edit, and go to the next.  It will keep track of your
line insertions and deletions such that it will go to the next error
correctly.  If you have the x-enabled version, once your focus is inside
the compilation output window, you even have buttons for 'goto next
error', 'recompile', etc.

 

Others love VI/VIM/VI.  But let's not get into a flame war
over kitchen sinks vs VI ;-)

 

Or one of the IDEs you mention might work also.  But beware - my (very
limitd) experience with eclipse is that it makes the kitchen sink editor
look small J

 

Um, you are using ubuntu?  Isn't the plugin there in synaptic?  Yeah,
there it is - eclipse-cdt.  So: "sudo apt-get install eclipse-cdt" if
you don't want to use synaptic.  (I've not used eclipse on linux, so I
have no idea if eclipse-cdt will work with g++, but I'd be a bit
surprised if it didn't)

RE: Looking for Router Suggestions

[Carruth, Rusty]

Actually, Mike brings up a good point - unless your interenet provider is 
faster than 100Mb/s then the best you can do from the 'net to the entire rest 
of your inside network is 100Mb/s or less.

so a gig switch connected to your firewall/internet router, which has a 100Mb/s 
link, is probably fast enough.  I assume you want the gigE from machine to 
machine, so you should budget for a higher-end gigE switch (or router) than for 
an internet-facing box with multiple gigE.  Or at least consider the speeds, 
and try to get a gigE switch/router that can give full data rate (full duplex) 
between all ports at once.

If you really want a router with 2 interfaces for "outside" and

RE: OT: Is it possible to make a printer wireless?

[Carruth, Rusty]

WHOA!  I bought mine a few years back for under $100, AFAIR!  Wow!

On the inkjet vs laser - I was a died-in-the-wool Laser fan for years
(still have a soft spot in my heart for a good old laser printer - and
indeed I even have a color laser printer at home that someone threw away
some years back.  Replacement set of toner thingies is about $120 - but
very nice to not have to worry about them drying out!)

And up till recently I've spent more on new ink cartridges for inkjets
than the crazy printer was worth!  Until a friend mentioned that new
printers keep track of when they need to print to avoid drying out the
print head (as long as you keep them powered up), and that he's had
great luck with refillable cartridges.

My cost on the refillables is amazingly low.  Bought one set of
refillable carts a year or 3 ago (to replace the previous set I'd had
that died) (cost was under $40 (And ISTR under $20) for all 4), and 2
sets of refill ink (about $10 per set) since then.  And my family prints
a fair amount...

My only complaint is that the stupid Epson printer every once in a while
decides that it doesn't like the non-Epson cartridges, and you have to
fiddle with the stupid thing to get it to like them again.  I'm not
completely happy, and if I die my wife will be out of luck (probably
switch back to the laser printer)...

2 - figure a way to run an etherhose from the nearest network location
(assuming it's a network printer - or from the nearest network pc if
not) to the printer location (its not always as hard as you think to do
that J)

3 - get an old PC with wireless, install Linux, set it up as print
server.

Kenn,

Thanks for the suggestion. The servers do have static IPs, and the box
in question got its IP from my DHCP server. I looked for possible IP
collision and didn't find any. I also tried giving the box a fixed IP,
and no change.

Could it be using an IP already in use, or the wrong subnet, or grabbing
an IP from a range you've reserved? It probably wouldn't work at all if
it was, just thought I'd throw it out there.

I have a 100baseT network with several Debian servers, a mac book, and
some virtual windows. I just picked up a Western Digital My Book Live
(MBL) 2TB NAS at Costco, and powered it up on my network. The unit is
just sitting with its green light on, and the web interface is really
slow. When I ping the device, it shows somewhere from 50% to 86% packet
loss. If I ping any other computer on the network I have 0% packet loss.
I have tried moving the device to different physical plugs, and I get
the same results. 

ping results for the MBL from server A:
--- 192.168.25.213 ping statistics ---
330 packets transmitted, 152 received, 53% packet loss, time 329555ms
rtt min/avg/max/mdev = 0.208/0.273/0.650/0.048 ms

--- 192.168.25.213 ping statistics from server B ---
254 packets transmitted, 120 received, 52% packet loss, time 252998ms
rtt min/avg/max/mdev = 0.196/0.264/2.499/0.206 ms


ping results for  server A to B:
--- 192.168.25.130 ping statistics ---
340 packets transmitted, 340 received, 0% packet loss, time 338996ms
rtt min/avg/max/mdev = 0.080/0.177/0.246/0.030 ms

The device says gigabit Ethernet next to the Ethernet port. Is there any
reason I can't connect a gigabit Ethernet device to a 100baseT network
other than the obvious speed difference? Should I see all this packet
loss? This is actually the second unit I have tried - the first one
acted the same way, so I took it back. I am now wondering if I am doing
something wrong.


Thanks!

Mark

RE: Strange Server Behavior

[Carruth, Rusty]

Well, I had to ask J

 

I'd say its 'divide and conquer time' like I suggested earlier - enable
half (approx) of the services and run the test.  If it passes, turn
those off and then turn on the other half, rerun test.  If it passes,
life gets hard, and I'm going to ignore that possibility for now!
Whichever test fails, repeat the above with that reduced set of
services.

 

If both halves pass, then there is some interaction between the
services, and it's not so easy as divide and conquer.   (but of course,
if a service depends upon another one to be fully functional (apache and
mysql are likely examples) then you'll have to keep those services
together till the bitter end (as it were)).

 

However, there is still hope someone here has another idea...

Rusty,

The test was run from 11 PM to 7 AM, so no one in my house was doing
anything but sawing logs, as far as I know. Yes, teenagers tend to stay
up late, but I would have heard the tv. I don't think any of the other
machines are really doing anything at that time as well. 

I don't think anyone is using my wifiI have a 64 character key for
AES and mac address filter for security. Yes, I know one can eaily spoof
the mac address thing, but it keeps some out. I also have not seen
anything strange in the logs.

Rsync is a good idea, but I agree - fragile, lots to set up, but maybe
worth a thought if nfs tends to be the problem. Maybe a script to check
if a local folder has changed, and then rsync it

RE: Strange Server Behavior

[Carruth, Rusty]

Personal guesses, YMMV, YKWYPFI (you know what you paid for it), etc:

 

If you don't need NFS, leave it off.  When I saw it in  there I thought
- oh, my.  For NFS clients, I know you can freeze a system when the
server goes unresponsive.  Or I think I know that J

 

Of all those things, are there any you are NOT using?

 

Besides the ping test mentioned earlier, I suppose you could start
dividing and conquering (turn back on half the items below, run the
test.  If passes, run the other half to verify that the mix of the other
half will fail, THEN split the failing half in half and repeat).

 

I can't recall if I've ever seen a hung printer hang cups enough to hang
the entire system.  It will hang printing, of course, but...

 

In any case, yes it sounds like some sort of hw/sw interaction or maybe
just sw.

 

Good luck, Mr Phelps!  ;-)

RE: Strange Server Behavior

[Carruth, Rusty]

Curious how your test turned out.

 

You may also want to run an iostat to a file and see if that correlates
to the slow responses.

 

However, that 'bulging capacitor' thing others have mentioned sounds
like a pretty convincing coincidence, as it were

 

(I will say that USUALLY I'd agree with JD - Iobound or low RAM (and
thus iobound on swap space) are the only things I've seen that cause
unresponsiveness (never seen an overheat slow it down, usually it just
dies suddenly.  I probably get fast overheating and not slow increases
in heat levels J)

 

OH!  WAIT!  I just remembered another event - and it WON'T show up in
normal performance logs.  If 'you' send a command to a disk drive, and
it goes busy for a long time, your system can become totally locked
until the timeout happens and the kernel gives up.  (If that happens,
there SHOULD be a timeout recorded in the syslog or /var/log/messages.
Check there for timeouts on disk drives or hard resets or such).  (I
know this because of where I work J)  (Disk drives are supposed to
acknowledge the command almost immediately.  It is almost always a bad
thing when the drive takes the command but does not finish the initial
command handshake sequence...  You might want to look at the S.M.A.R.T.
attributes for your drives as well to see if any of them are showing
'pre-fail' conditions)

RE: Need Help setting up a VPN Connection to my LAN

[Carruth, Rusty]

Actually, using VNC you can even get GUI access with a 'local' ssh
forward of the VNC port.

Been there, done that, it works.

Check out these 2 ssh command lines:

ssh -L 5902:there:5902 me@overthere

This will ssh into 'overthere' as 'me', and once you are logged in
'overthere' it will forward port 5902 from the machine on which you
STARTED the ssh session to the VNC server (port 5902) on machine 'there'
- which for best results is over on the same subnet as 'overthere' :-)

In other words, say "ssh -L 5902:vncserver:5902 me@vncserver" then, once
you are logged in, from the same machine on which you did the ssh,
connect to 'localhost' using VNC client - and you are instead talking to
the vncserver's VNC (:2 or :1, I think).

ssh -R 9283:there2:9283 me@overthere

As before, once you have gotten logged in as 'me' 'overthere', it
forwards a port, but this time from the 'overthere' side back to your
side, so that 'there2' should be on the same subnet as the machine from
which you started the ssh.

Note that there is NO requirement for the two port numbers to be the
same value.

If that's confusing, sorry, but ssh DOES tend to be a bit of a swiss
army knife!

RE: OT: Dell disks

[Carruth, Rusty]

Disclaimer time:  I work for an SSD manufacturer.  We sell high-end 
'enterprise' SSDs.

However, while some of what I say is based upon my experience there, NONE of it 
is official, and all of it is my personal opinion.  Just remember what you paid 
for it! ;-)

There are at least 2 levels of 'SSD' - enterprise and consumer.  Contrary to 
what was said about rotating drives and that weird 'error fast' thing, in 
SSD-land there is a large difference between 'enterprise' and 'consumer'.  
Enterprise drives are designed to run at very near full rated TPS and/or MB/S 
continuously 24x7x365.  Consumer drives won't last anywhere near that.  
(Consumer drives are often implemented using the same technlogy (and expected 
lifetime) that is used in memory sticks.  If that doesn't scare you to death 
nothing will :-))

In any case, I'd look at the smart attributes.  Use smartctl -a and see if 
anything is nearing the threshold.  Send the output to me personally if you 
want me to look at it, I'll be happy to.  (As long as I don't get 2,000 of 
those tomorrow, anyway! ;-)

And some other day I'll say what I think of RAID 5 :-)

So yeah, no raid is perfect...



To its testament, it rebooted, both disks reported healthy (hdparm, 
ubuntu disk utility), I re-added each partition, let it rebuild, and 
works again.  Still worries me as my last set of ssd disks got unstable 
on one after less than 9 months of use and I'm probably about there with 
these that are known to get cranky.  Smart reports them as ok, so I 
wonder how bad ati taints the kernel space that it causes disk 
controller/driver exceptions.

Moral of story: know when/how to repair whatever raid, as software and 
hardware are seemingly still prone to exception from unlikely places. 
Last time a disk died with md, I just mounted the secondary in an 
enclosure, copied off data as pluggable, and copied to the new pair of 
raid disks.  Hardware is never this easy, especially fakeraids.

RE: Which linux distro

[Carruth, Rusty]

Yeah, I'm still at ubuntu 10.04 *entirely* due to Unity.  Gag me - I have a 
COMPUTER, people, this is NOT a phone!

Oh, sorry, I'm back on that soapbox! :-)

But, anyway, yes, I *can* use just about any distro, but I use Ubuntu because I 
want it to work and I don't need to prove I can do hard stuff.  But then, I'm a 
native Unix/Linux speaker..., so YMMV!

RE: What's the best high speed internet option?

[Carruth, Rusty]

Tmobile has a sort-of unlimited option.  You decide how much 'high speed
capable' internet you want per month 500M, 1G, 2G, IIRC).  When you
exceed that, you 'automatically' fall back to slow (I'm guessing 56K).

 

Beware that even if you force your phone (or whatever) to slow speed
TMobile still counts the usage as 'high speed capable'

syslog stuff (was RE: wireless stoped working)

[Carruth, Rusty]

I didn't know it all, but I do know that /etc/logrotate.conf and
/etc/logrotate.d control, well, log rotation.

 

ISTR that "In the old days" syslogd would use 2 criteria to decide
whether to rotate the log - size of file and how long it had been since
last rotation.

 

I don't remember all the rules (like, if the file is zero length, does
the rotation happen anyway, or not), but do remember that you could get
a log rotated either because of size OR time.  A perusal of
/etc/logrotate.d/* will reveal a lot of interesting stuff...  (Along
with a man page perusal J)

 

Notice that there are nifty 'commands' like 'rotate 10' and 'weekly'
which tell syslogd to keep 10 's copies of the
logs ('rotate 10'), and rotate the log files once per week ('weekly'),
regardless of size.  There are others, like 'compress' (to compress
them), and 'delaycompress' which apparently does not compress the 2 most
recent backup log files.

 

So, this means that somewhere in the configuration you should find
'daily', 'compress', 'delaycompress', and 'rotate 8' being applied to
/var/log/syslog.

 

On a slightly different topic, I have found that some versions of 'less'
will automatically decompress compressed files to text.  Or at least,
one time I mistakenly said 'less /var/log/syslog*' when some of them
were zipped, and LO! I didn't see any binary junk - it decompressed them
for me.  YMMV!

RE: merge documents with scp

[Carruth, Rusty]

The thing that MH said, without explicitly saying it, was that having
the / at the end of the source 'file' tells rsync to sync the
directory's CONTENTS, not the directory.

 

That is to say that this:

 

rsync -av ~ someone@somewhere:/home/someone

 

And this:

 

rsync -av ~/ someone@somewhere:/home/someone

 

Are seriously different.  The former will place '~' inside /home/someone
(if current user is 'me', then there will be a directory called 'me' in
/home/someone which is a copy of '~'), whereas the latter will result in
the CONTENTS of '~' on the local machine being copied to /home/someone
on the remote machine.  At least, if I remember the rsync man page right
J.

 

One further note.  This:

 

rsync -av ~ someone@somewhere:/home/someone

 

and this:

 

rsync -av ~ someone@somewhere:

 

Should result in the identical results, assuming that 'someone's home
directory on 'somewhere' is /home/someone.

RE: Ubuntu Desktop vrs Server versions

[Carruth, Rusty]

Cannot answer the question, but I can tell you where to look to see why
the system is no longer on the network.

 

On the box which is no longer seen by the rest of your network:

 

First, check to see that the Ethernet device you are connecting to the
network is up and configured.  Use ifconfig for that.

Next, make  sure the routing tables are correct.  Use route for that.

Next, make sure you can get outside.  Easiest way is to go to a remote
web page.

Next, instead of using 'localhost' as the name for the machine, try
using its externally-visible IP address.  E.G. if it is 10.5.1.2 then
use 10.5.1.2 instead of localhost for one of your 'inside the box'
tests.

 

All that will verify that the box is on your network and listening to
the external IP address to serve requests.

 

Now, from a remote machine, try to ping that machine.  If it answers,
then you can reach it and things should have been working.  Note also
that pinging or tracerouting with a port number can reveal listening
issues as well.

 

If you know when the change from working to not working happened, do a
find from /etc for any files which have changed since that 'known time'
(e.g. find /etc -newer )

 

Of course, this is all generic stuff, Lisa just said something very
ubuntu-specific.  See her info first, but for everyone else the above
might help in time of need J

Subject: Ubuntu Desktop vrs Server versions

 



Hi

 

I have a small Dell box that I have been using off and on for misc work
related sw testing (started with v 9.x Desktop).

 

I need to ramp up my personal training (as I am looking for work at the
moment) and have a question for the group.

 

Currently I am running 12.04 Desktop version with Apache, MySQL, OpenSSh
and some other server packages installed. I will be installing Oracle
next week for my next training project. However after the 12.04 upgrade
I find that I can not access the Desktop Ubuntu machine from anything on
the local network. I can access apache, mysql locally. A local ssh
connections works just fine. Just can't do any of them from outside the
box from anything on my home/local network.  I don't think there are any
running firewalls, so I am discounting that as an issue. 

 

Would a fresh install of the Server version be a better long term
solution for working with those type of packages, or should I stick with
my 4x upgraded Desktop version?

 

and

 

Does anyone have any suggestions as to what I can look into to resolve
my network connection issue ?

 

Thanks

Joe Gibbs

The remote machine's /etc/ssh/sshd_config file must have "X11Forwarding
yes"
in it, I thought.  sshd's default is to set that to no, isn't it?

> Then, 'ssh -X me@overthere'

And if that doesn't work, try "ssh -Y remotemachine" since -X can run
afoul of
one of X's security extensions.  At least that's what the man page said,
and I
had some trouble using -X a while back while -Y worked.

RE: hard drive won't shut off

[Carruth, Rusty]

One quick way to tell if any partition is currently 'dead' is to do an
ls of each mounted directory (e.g. if /dev/sdb2 is mounte on /mnt/foo,
then ls /mnt/foo)

 

Let us assume you have 10 partitions mounted, spread all over the
various disks, but they are not all someplace handy like /mnt.

 

So, for a quick 'hey, is it dead' sanity check, do this:

 

ls `df -kh|grep -v 'Mounted on' | awk '{print $NF}'`

 

If you get no errors, it is not QUITE time to panic J

 

If you do, you probably found the offending partition(s).  Also, check
/var/log/messages after that to see if you see any error messages
pointing at a certain drive (even if you don't see any errors in your ls
trick above).

 

And to the great suggestion of using smartctl (wish *I*'d thought of
it!) - if the drive supports SMART that's the first line of defense -
use smartctl.  If not, and the drive is making funny noises, try the
above.
