It has been a few years since I worked on Sun

hme0  is an ethernet interface on a card with a single interface.  The 
second card would be hme1, of course.

qfe0is port 0 of a 4 interface ethernet module

I don't know what eri0 isbut more than likely a person using Sun 
hardware on a regular basis will know.  And, to my knowledge, their 
numbering system hasn't changed.

My "santa-list" for Fedora-14.. & is there a file-wash program?..

[Linda McLeod]

I run Fedora-14, mostly for a pix editing hobby like some use electronic
card-solitaire to relax, & music, & writing in "focuswriter"...  I'm not
on the Net at home.. The demons destroy my PC's OS twice a week..  Me
thinks it's a "hungry falling libido thing" for them...

I note a few little glitchy areas in this OS, which seem to "slap &
destroy" sensitive writers rolls..  I can't use Fedora, or any OS to
write when I'm one, two, or three, "rungs-up in intellect for topic
rolls"..  The glitches irritate me out of my fleeting extreme focuses
I wish those thht-glitches weren't so in my face, like "a bad smell"...  
I've posted in forums about them..  All I get is flamers "pissing in my
face" and people who really don't have a tiny clue even what my
questions are about...


My "santa-list" for Fedora-14:  

There should be user controls to config everything about the desktop
screensaver slide-show..  Time-period pix's change..  sizes on screen.. 
maybe a "custom sized screen on screen"..  customizable background
colors.. slide intensities..  Hey! maybe even an OS systems link into
gimp via screensaver..? 
What would it take to have screensaver married to gimp..?
What can you do to screensaver slide show, or to a slide show, to make
it more interesting and enjoyable and fun, even funny?..  Is there a way
to make the PC project a slide show on the adjacent wall..?  What would
it take?..  
What would it take to have the PC project a slide show in the middle of
the room, without screen in the air..?

Controls to delete a pix from the OS should an unwanted screensaver pix
come up on screen.. and even edit it via a link to Gimp's wonderful
pix-laboratory...

User tools to config desktop:  simple r-click tool options to save
programs that are up on desktop, to be up on boot...

Fedora should have a base install of programs to show all Web activity
in & out, in real-time, with strong controls to block any and all
gorilla and demon activity...

I click up "home file" twice..  One window runs "pix file thumbs"..  the
other file window runs "home file".. to drop edited pix into various in
progress files and/or various theme files...
The problem is that home file pops-up in the middle of the screen when I
wants it to be snug at top & right screen..  
And second file drops right over top the first, thht!.. not at the
bottom right an inch from the bottom screen, showing only the top row of
files..  

"autospell" resets upon close..  I wishes it would stay clicked.. as I
wish "keep aligned" would stay clicked...

I don't connect my personal PC to the Web..  When I do, "government and
corporate brain-suckers are into it like bluebottle-flies on
fresh-poop", "tossing my room like it's their gilded-toilet", desperate
to steal the new technologies I say I have, after I offered to build it
for them for free..  

So, given this computer isn't pest connected, I don't usually need the
login password, mostly because I remove the hd, and take it, when I
leave the house..  There should be a timed control for the user to
disable login-password, so the computer goes from "press the button", to
"OS loaded".. because when I'm on a roll I needs physical-realm things
to run themselves, so I can hold the roll intact while the computer gets
started..  It ain't fun loosing a cosmical-roll because the computer was
off, and requires an easy babysitter to get it on.. User should have
option to disable boot hangups, by making "autoboot" an option...  Maybe
even add a timer that turns the PC on in a schedule..?

Ailurus should be in desktop r-click...  Ailurus and Gimp should tackle
some of these requests...

I wish the mouse was a lot faster..  I'm running a logitech marble mouse
for pix editing..  Over the years conditioned my flip of the marble to
land the cursor on any chosen common button.. but the cursor is way too
slow at fastest mouse settings.. makes me feel like the world is built
for "dead-turtles" and "tater-heads" and "bad-liquid people"..  If
artisans want different atmosphere they gotta die, or make it better, in
the war...

I really wish the cursor was a half inch cutlass.. metallic maroon...
I downloaded a sword-cursor once in W98.. It installed with 75
spy-trojans.. I had to format C, and lost my sword, cuz I didn't know
how to clean the crap that download set in the OS for their unscrupulous
project...  Their kind makes the Internet be dirdy and stinky, like a
sewer...

DBAN should be part and option of every Linux distro CD...

With a click of the mouse, user should be able to make an ISO of the
customized/personalized OS as it is for to install fully updated OS
without a Net connection, and without any grief...

I’m finding too much “ram slowdown” while I edit pix...  
Seems a few of these Web-pix have nasty snoop-bugs in them, which attach
themselves to running programs for zombie-class unkind preditorial
purposes against innocent targets..?  
Is there such a program as a “file scrubber”..?  ..sort of like how "cat
owners mu

There is something wrong with ethp2p3? What KIND of device is easier to fathom
if it is part of the name, ya know.

Seems new doggies have to prove they are big doggies by peeing on the
old dogs' work. "eth0" makes sense. "p4pl" sounds like an amateur radio
call sign from Aruba. It tells you nothing about the interface you're
dealing with. 'ix operating systems are already hard enough to use well.
Is there something hairy chested manly about making it worse rather than
better?

There's quite a good explanation of that somewhere, I think in the
bash manual. It boils down to:
X=A
is an assignment (to X)
X =A
is a command (run X, argument, '=A')
X= A
is an assignment (X="") followed by a command (A) run with that
assignment in effect (normally you need to export the value for it to
affect the child process).

Exercise left for the reader as to what
X = A
is.

 On my f14 I ran  'system-config-firewall' and checked the  IPP box,
 Network Printing Server (IPP)

as I responded to emilio, I am now stuck on 'paused printing'.
I guess this is better than 'busy'

 uhh, my iMac is the client trying to print to a printer on the f14 server.
 So my iMac doesnt have network printing clients, the iMac is the client.
 Are you  saying that in this case
 my iMac needs 'firewall opened to allow network printing clients'?

 My previous rececent experience [on my older version of
f14(preupgrade from f12)]
 says I _do_ need to do some configuring of CUPS on the iMac:
 (shown to me by Ted Roche on this list):
 need on iMac for 'cupsctl BrowseRemoteProtocols=cups';
 without that, the iMac then couldn't even see the f14 printer.

I don't mean to insist, but I had a similar problem and I was able to
replicate the old drive along with the partition table and LVM onto
the replacement drive using ddrescue. The procedure is documented in
this post.



Just thought this might be an appropriate (and simple) way to tackle

Yes.  In fact, I'm fairly sure that this is exactly what it was written 
for in the first place.  Using it in place of su for general system 
administration is a later adaptation[1] of the command.  I'm presuming 
that you want certain users to have access to all of the regular 
commands plus a small subset of administrative commands.  If so, sudo is 
the best way to go.

yeah...things were b0rked so badly I couldn't CTL+ALT+F2. I did manage to 
SSH in from another box on the LAN and went to runlevel 3, deleted the 
config file and went back to runlevel 5. Switching to the nVidia driver 
helped a LOT. I don't know the noveau driver was updated recently or not, 
but something was definitely hosed. Also, the nVidia driver didn't fix it 
100%. I'm still having issues with the keyboard and mouse not responding 
100% in xfce4. I wish I knew where that config file was kept as I might try 
renaming the config file and doing a repair install and see if that came with 
a new config file. I did find some default settings files for xfce, but I don't 
know if there is a per-user file somewhere that might be more important.

Re: restricted shell

[Hugh Caley]

Not precisely what you are requesting, but the "sudo" command could be 
used to allow your admin root access to certain commands only.

See "man sudo" and "man visudo".  The /etc/sudoers file has examples of 
this sort of functionality, but should only be edited using the visudo 
utility.

You can look into "chroot"ing, where the other person has a different
root directory, and all the sub-directories, and you copy the commands
that they're allowed to use into their directory tree.

Of course, to do this properly, you also need to make sure that they
can't use a compiler, else they can create their own commands.

Exactly.  Back when I did tech support for an ISP, I used to tell 
callers that having a dynamic IP address made their computer more 
secure, especially on dial-up.  Why?  Well, even if somebody managed to 
get into their computer they'd never be able to find it again once the 
owner had logged off the net because next time they'd have a different 
IP.  Yes, I knew about rootkits back then, but it was a case of KISS. 
Hell, I can also remember assuring callers that email viruses were 
impossible right up until the day the first one hit.

Re: OT: need bash help [solved]

[Pete Travis]

Backticks for a subshell are 'depricated' though the convention is still in
wide use.  I use the $() method because `su - user 'command --opt="foo"'`
and such can get a bit confusing,  and the alternative is much easier to
pick out of a mass of text.

Thanks. It's not that bad. Yet. I just know that SMARTD is apparently 
telling me that the drive is failing. I don't have a replacement yet, but 
hopefully I'll have one in the next day or so. Then I have to figure out how 
to get the data to the new drive and make it the boot drive (my boot drive 
is a small PATA drive and it's the one that is failing!)

Try wrapping your command to make a subshell:

LINES=$(ps x| grep mongod | wc -l)

You can use:

LINES=`ps x | grep mongod | wc -l`

(using back ticks to bracket the command)

Aaargh!  Doesn't like the spaces around the = sign.

LINES=`ps x | grep mongod | wc -l` is a way to write it.

OT: need bash help

[Mike Wright]

Hi all,

I'm trying to write a bash script and having problems.

If I execute this:

   ps x | grep mongod | wc -l

it returns a value.

OTOH, if I execute this:

   LINES = ps x | grep mongod | wc -l

it returns "command not found".

How does one assign the output of a command to an environment variable?

TIA,
Mike Wright

your understanding of security is simply broken

security is always a bundle of preventions and not a single thing
MAC filter is not thought as the only security layer
it is an additional one in a multiple secured network

it prevents 90% of all users out there to connect and if you
get only one of them in your network with malicious software
on it this one can not send spam over his zombies

all the little pieces and optimizations in summary give you
security, not any single configuration alone

if you have 5 easy to break security barriers in front you make it
real hard for most people without enough knowledge of all these
barrieres to break them all - nobody said these are the only
preventions - these are ADDITIONAL ONES

What I was trying to view is:

... and FF says it needs a plugin which it cannot find

so why do you not install the adobe-repo and after that "yum install 
flash-plugin"
in the meantime there is even a x86_64 plugin and yes it works on F14 also as 
on F15

Re: Remote access

peopole like you are a real nightmare because you are enforcing

the same for recommend to setup openvpn
you can do that at your home but NOT in a company

the company may have well tested rollozts and security checks on all

why?

On my f14, I did  'system-config-firewall'
and checked
Network Printing Server (IPP)

now I get  a different response when trying to print from the iMac

initially it acts like it is starting, but then goes into 'paused' state
I can click on resume printing, it again seems to start,
but immediately again goes into 'paused', and I can't break out of this cycle.


I do have the 'sharing' and 'internet' boxes checked on the admin page.

I bought an adapter to connect the headset (3.5mm jacks) to USB. Works.

Could be part of my disk is trashed. I logged into Gnome as a test (didn't 
like the lack of desktop icons, another reason I don't use KDE any more!) 
and got notification of a hard drive error. I'm working on getting a new 
hard drive, so hopefully I'll be up and running 100% in a few days. Might 
have to do a refresh install of xfce4 or something and see if that helps.

F14 misbehavior of gnome-session-properties

[Beartooth]

F14 fully updated has been failing, on cold boot, to restore my 
gnome terminal, which is 2.32.0. I have the gnome-session-properties 
option set to remember running applications when logging out, and it does 
always come up on Workspace 1. But that workspace, where I keep a 
terminal with six or eight tabs open to three or four different profiles, 
boots up blank. 

This morning, in fact, all workspaces were blank. (I have 16 at 
present.) There should've been another terminal on another space, a 
couple of browsers, VirtualBox, and Pan 0.133 on still others. 

Is this something I've done, or a bug?

So either it's something in Fedora (probably something old), or 
in Linux even more generally. Anybody know what other distros it shows up 
in, if any?

I had another cursor incident yesterday evening, maybe related, 
maybe not. I keep my cursor set to be as big as I can get it; when it is 
on the desktop, it's mostly (not inside some apps) pretty conspicuous. 
Yesterday, while the cursor was both conspicuous and moving, almost 
everything in the display suddenly froze. 

It didn't respond to Ctrl-Alt-Backspace, nor even to Ctrl-Alt-
Delete. This machine doesn't have a reset button separate from the power 
button; so I tried giving that one a quick punch. No joy there, either.

I have System Monitor 2.32.0 set to display two blocks on my 
bottom panel, one for the processor and one for the network. Both 
continued to show movement, and neither was anywhere near maxxed out. But 
that big cursor just sat there and scoffed at me.

I finally held the power button till the whole machine shut down, 
and left it overnight.

Updating F14 will soon stop. And no attempt has occurred yet to update
Firefox passed firefox-3.6.23-1.fc14.i686. While Firefox has gone to
version 4, 5, 6 and 7. When do you predict firefox will be updated in

VNC apparently correctly anticipates what's on the other end.  Your
system is confused about either your video card or the monitor for
your console.  Were it me, I'd be plugging in other video cards and/or
monitors just to see what happens.  I would also take seriously the
possibility that part of your disk is trashed.

And the answer from the link is no, Fedora 14 doesn't have a packaged version 
of Firefox 7. You have to use the remi repo for that, which is a 3rd party 
repo. So if you have F14, there is no such thing as
"Fedora packaged Firefox 7".

But what I would like to know (and Rahul's link doesn't explain) is *why* F14 
doesn't have FF7? At this point F14 will be EOL'd soon, so it doesn't make 
sense to update FF now, but it did make sense several months ago. Why wasn't 
it done?

Best, :-)

That is true. But I run what I can get. Does Fedora have a packaged
version for Firefox 7.
The latest version in F14 repos is: firefox-3.6.23-1.fc14.i686

Suppose you have a server with a two-port ethernet PCI card plugged into the 
second PCI slot on the motherboard. The biosdevname names are p2p1 and p2p2. 
By your definition, they would map to eth0 and eth1, right?

Now, at some point you decide to upgrade your hardware by adding an aditional 
two-port ethernet card in PCI slot 1. The biosdevname names for the new ports 
are p1p1 and p1p2, while p2p1 and p2p2 stay the same, as before. But this 
time, according to your proposal, eth0 and eth1 would not correspond to p2p1 
and p2p2, but to the new ports, p1p1 and p1p2, while the p2p1 and p2p2 would 
be renamed eth2 and eth3. Assuming that you plug all the cables back to their 
original positions, every script that refers to eth0 and eth1 is now broken, 
while every script that refers to p2p1 and p2p2 still works.

IIUC, this is one of the problems that biosdevname is meant to fix. The concept 
of physical location is a well-defined one, while the concept of linearly 
ordered (lexicographically or otherwise) location is ill-defined. Hence the 
names are given according to the physial location rather than to any 
particular ordering.

Best, :-)

network printing clients.  This allows UDP traffic over port 631.
Fedora has a preset option for this in its firewall control panel.

The CUPS server needs configuring to allow sharing of its printers, and
the setting up of the printer connected to it.  If it can print a test
page, then any client should be able to.

The CUPS clients shouldn't need any configuring of their CUPS service,
and attempting to do so can cause problems.  They should simply find the
available printers on the network, when the above three conditions are
set up.  The only printing configuring that should be necessary, is
choosing a printer to print to, when you try printing from a program.
But, if there's only one printer on the network, it should get
automatically chosen as the printer to use.

Not knowing how the iMac reports its errors.  I couldn't say whether its
"it's busy" error message means it couldn't get any TCP/IP traffic
through the network to try and print, or it has got through to the print
server, and the message is that the printer (or printer server) is busy.

You can look at the print servers logs, to see if some attempt is
getting through to it.

Right... if I go into "systemsettings" and try and specify any of the 
settings, it creates an xorg.conf file which pretty much messes everything 
up... no X, etc.
What happened was I'm on a KVM, and I let the system boot up while the KVM 
was switched to another computer. As usually happens the screen was HUGE! I 
tried rebooting, I tried specifying the settings, nothing worked. Now my 
best resolution is 1024x768 and I need to go to 1280x1024.
Any time I try and specify any settings in systemsettings, it messes things 
up as mentioned, so I'm at a loss.
Any suggestions?

Except you often can't tell the difference. Not all hardware exposes the
connection interface, and then you have things like SATA devices in USB
boxes - so which of your naming is those.

Instead they are named by transport type but how that is presented is up
to the udev userspace.

I would have gone down the route of calling USB devices with a usb
device name.  So a USB device doesn't become sda and shuffle device
names around for *other* devices.

And I would have left IDE style devices as hd, SCSI as sd, SATA as sa,
and so on, and so forth...

That way when I have a computer with an internal IDE drive, an external
USB, and an external SATA, I could tell them instantly apart from each
other as they would be /dev/hda, /dev/usb1, /dev/sa1.  Rather
than /dev/sda, /dev/sdb, and /dev/sdc, where I could guess that the
internal drive was *probably* /dev/sda, but could never guess what
either of the other two were.

System-wide profiles don't seem to find debug information since Fedora 15

[Clemens Eisserer]

Hi,

I have been using Sysprof for quite some time, but with Fedora 15 it
stopped working properly.
Where it presented pretty stack-traces including timings in Fedora 14
when debuginfo-packages where installed, it just presents very cryptic
and less informative information since F15 - usually this was only the
case when debuginfo-packages were not installed.

Today I tried oprofile instead, but got the same results - I just get
results with binary granularity:

Run palimpset, click the disk, click "SMART data", then tick "Don't

Red Hat seems to like to ship tools with the slightly questionable view
that a disk reporting plenty of bad blocks is 'failing' when in fact what
actually matters is whether the lists are growing and what the drive
smart data reports.

hdparm can give you a much more honest appraisal of your disk, and
usually modern BIOSes check whether the drive thinks it is failing on
boot (make sure SMART is enabled in the BIOS)

Turning Off GNOME Warnings

[Dave Cross]

GNOME seems to think that my laptop has a dodgy hard disk. It's been
telling me that for over a year. I'm not sure that it's correct, but
I'm keeping a close eye on the situation anyway.

Under GNOME 2 I would get a notification of this problem each time I
restarted the computer. A pop-up would tell me there was a problem and
I'd close the pop-up and forget about it.

Under GNOME 3 this notification is rather more persistent. GNOME
insists on repeating the pop-up every twenty minutes or so. This isn't
realyl very helpful.

Is there any way to get GNOME to revert to the previous behaviour
where I'm only told about a problem once?

Cheers,

Dave...

In which case there is no such thing as 'security' because if 500 US
marines with automatic weapons crash through your windows your security
model fails.

It sounds like port 631 is closed in Fedora Firewall. Did you check that?

You should see cups admin page at http:\\your-fedora-ip:631

Right, so PackageKit thinks you've got a high speed LAN connection. I
don't think there's anyway of telling NM that "This network is high
cost" manually, other than keying off the connection type.

I'd say the fact that it *cannot* be used to "secure" a system, means
that it does have nothing to do with security.  There is no way, shape,
or form, that you can enforce security using MAC filtering.

Yes, it can be useful in basic network management, but that's not
security.  I stand by my analogy, that's all the effect it has.

Turning the power off to the VDU may make it harder for me to mess up
your computer, but it's *not* securing it.  There's a whole pile of
things that may be small obstacles, but none of them are security.

Usually, you can CTRL+ALT+F2 (or one of the other F keys), over to a
text console, on the same computer, to use the command line.  If that
works, then it saves you a bit of hassle to work through this problem.
Though, it can happen that the graphics system gets so screwed up you
will have to SSH in.

You should probably post the xorg.conf file for some other people to
look for anything wrong with it.

The other suggestion of removing and reinstalling X is usually bad
advice.  If there's a problem with the package, you'll be back at square
one.  The re-install will fail, just the same.

Likewise, if the package is fine, but a configuration file isn't.  Most
configuration files that are not provided directly in the package, such
as ones created later on, or ones that were modified, will not be
removed during a package removal.  A re-install will use the same
configuration file.

If you think the installation of a package is broken, you can check for
that using the rpm tools own verification options.

Please don't do that, I would thing that would cause you a whole lot
of more troubles. I would first try to boot by removing the old
xorg.conf out of the way (I'm assuming you use xorg.conf since you
mention nvidia-xconfig). Xorg these days doesn't need an xorg.conf, so
might as well start with that. Also have you run fsck on your disk? As
root `touch /forcefsck` and reboot to do that.

Hopefully that gets you started.
