Sorry Ed,

I didn't mean to be rude in not replying, but I got hit with a problem
in $REALLIFE.

What I meant by this was what settings should I use in /etc/msmtprchttp?

What I had at that point was in the bit of my mail that you trimmed in
your reply:
> > logfile /var/log/msmtp.log
> > tls on

> > tls_starttls off

I tried taking out (commenting out) the tls stuff. No joy. I tried
altering the "from"... Success! I changed it to be "m...@mydomain.org".
"mark" is a valid user on this machine. Is that what the problem was? If
that is the case I didn't spot anywhere that it was a requirement that
the "from" be a "valid" user.

Anyhow - it now works. The strange thing is that I had not re-enabled
the tls settings and - even though Blueyonder insist that connections
should be made with SSL - it still works!

Thanks for all your your help.

Mark

Try using -x or -y options with the ssh command.  It's the usual culprit
when you want to use a graphical tool over ssh.

Thank you very much.
You were quite right - after changing the command to
  ssh -Y grover knode
all works well.

I'm using this method now, with a KDE button
(created by right-clicking on the K icon)
to start knode on my server.

There are one or two quirks to iron out,
but they are probably due to the fact that knode is running under CentOS,
the OS of my server.

At the moment I am short on time, so cannot experiment with sage.  That
said, Fedora has a long standing packaging effort for SAGE[1].  It seems
to me sage needs a TeXLive-like distribution model to be not so
intimidating for new users.  This however does not make the effort
required to include it in Linux distribution respositories any simpler.

I'll try compiling my own in a few weeks when I have some more time and
report back.

I have a similar build system for SLC 5.7.  Our software can also be
deployed in a VM; I have tried that but found the overhead of using a VM
(build times, test job run times and the fact that you have to have a
working virtualisation setup) rather large.  Instead now I (and many of
my colleagues) use a few scripts to maintain the chroot system for our
software.  This also seems easier to implement across multiple linux
distros without much fiddling (it's after all a few scripts that uses
chroot to setup the environment).  To give you an idea about the "easy
on various" distros bit, we have tried this on Arch, Ubuntu, Fedora and
Debian.  Getting it to work on Fedora required some extra effort to get
the SELinux labels for the chroot'ed directory hierarchy correct.

Hope that answers your question.

There seems to be a lot of hatred here (even in this thread) for the
multi-window interface. But I, for one, wish that *more* applications
implemented it.

It is seriously the only way to go when you have multiple monitors and
edit a lot of images simultaneously. (Try to imagine stretching a
single-window interface across three screens. Ick.)

The flipside to this would be only having a small laptop screen to work

Byobu

Hi, all.

After the last kernel upgrade (=> 3.5.3-1) notifications in Byobu ceased
to work (amongst other things: an existing kvm machine no longer works
as Nautilus keeps crashing when it's launched so I had to re-install that).

I've tried reverting back to 5.17 with no luck (both via Yum & compiling
it myself), newt-python which is what Byobu uses for notifications, is
all present & correct & I can't find anyone in the same position as
myself on Google.

Has anybody on the list seen this anomaly?

Cheers,

  Phil...

When is the last time you had to type the ".exe" in order to run a file

Try editing GRUB_CMDLINE_LINUX in /etc/default/grub. Remember to update
grub configuration with: grub2-mkconfig -o /boot/grub2/grub.cfg.

You may also try to pass nomodeset as command line parameter in grub's
boot menu to see if it works.

Just reading through this thread, I’d thought I’d make a couple of
comments.

One is that whenever you’re sending email through someone else’s server,
there’s the possibility that email might fall foul of a counter-spam
measure, and you can’t tell what those measures really are.

This is still the case when you’re sending as an authenticated user and
you have some sort of relationship (business, for example) with the
server’s owner. A system like smtp.blueyonder.co.uk is unlikely to be
blocked even if it does send the occasional email. That makes it
valuable to spammers, who can obtain valid login details from
compromised Windows systems (or phishing, or using stolen credit card
details, or a number of other routes). Once they’ve done that, they’ll
try to send as many emails through as possible before they get caught.
There should be systems in place to try to minimise the damage when that
happens.

I think that’s what you’re experiencing: changing minor details like the
from name doesn’t affect whether the SMTP conversation works (the
recipient has no business checking whether the “from” user is “valid”),
but it can affect the spam filter logic. If smtp.blueyonder.co.uk is
expecting only real users using end-user MTAs to relay through it, then
it might be configured to treat noreply@ and other signs of “this has
come from a PHP script” as spam indicators (quite possibly in a
scoring-based system similar to SpamAssassin).

And the key point here is that you’ve only “fixed” one of the possible
spam indicators, the weighting may well change in future (so it may well
break when you haven’t changed anything), and the number of emails sent
per hour may well be factored in to the filter.

If this is for home use, you might well decide just to live with all this.

The second point is why you didn’t need SSL/TLS. I suspect this is just
because you may have turned TLS off, but you might not have turned
authentication (passwords) off: msmtp will use secure login methods over
unencrypted connections.

Alternatively, if smtp.blueyonder.co.uk is configured for incoming email
as well as relaying to the outside world, it could use the presence of
SSL or TLS to select what it does, and even without a login it might
accept email for your domain in the same way as it would from any other
server.

(Does dig -t mx +short mydomain.org mention smtp.blueyonder.co.uk at
all?)

Hope this helps,

James.

P.S.: if you ever plan to send email from web pages to random addresses
on the wider Internet, please think about how that could be misused!

You can also use the old chkconfig and service commands -- they forward to
the systemctl actions.

The new system is certainly more wordy, and the user interface could
probably stand some refinement for real-world users. For this simple action,
it seems particularly over-wordy. This supports a more flexible system, but
when you're just trying to enable ssh you probably don't really care.

As eventually everything is converted to systemctl, making 'service' be the
more user-friendly interface for the simple case may be the best way to go.
What do you think?

HUH! it's so obvious! nevertheless, I'd have thought that would change the
property for only that one file. but it seems to do what I wanted.

Hi, Suvayu.  It's possible I was just lucky enough to have all the required 
dependencies already installed, but in my case it took less than a minute of my 
own time to download and build sage (e.g., "wget ...; make").  It did take a 
lot of time for the file to download and the build to complete, but I didn't 
have to do anything while these were ongoing.

It is seriously the only way to go when you have multiple monitors and

The flipside to this would be only having a small laptop screen to 
work with and not wanting to switch to various windows constantly in 
order to get something done in GIMP.



EGO II
Not so at all, There is no hatred, just discussion of merit one way or 
another.


Both my daughters use multi window Gimp, as is, on 3 or 4 laptops, they 
also do not see any reason to change to a one size fits all prospect.
I use Gimp on a multi monitor desktop and on an old Dell 1520 laptop and 
have no problem with multi screen.


An analogy would be that on my work bench in my shed, a real life 
situation, I could not work if the periphery was taken up by all of my 
tools of which I use one at a time, no! they get put back on hooks, on 
racks, in drawers. This is Gimp, putting the tools away until needed 
once again.

Gimp multi window is for me, like my hard copy work bench. A delight to use.

Alienating Photoshop users is an entirely different subject, not related 
to Gimp single or multi screen use. It really should not be part of this 
discussion. It implies that they have a mental block prevention from 
learning new ways. I do not believe that to be the case.
Photoshop users will not and have no reason to change. They are happy 
with their expensive image manipulation software.
There are millions of new users out there who do not want photoshop and 
it is those who need to be told about Gimp. They will learn multi window 
quickly.


One of my daughters, mentioned above, is a secondary teacher at a 
private college. She used photoshop for a few days because her students did.
Removed it and went to Gimp, as did all of her students who no longer 
complain loud and long about having to use such a crap application that 
broke continuously.


There are reasons for and against every GUI, but from my experience, no 
one I know wants to revert to photoshop because it is too difficult to 
use when compared to Gimp with it's multi screen.

I have built Sage on Fedora 17 and RHEL 6 with no difficulty.  It is a
big ugly package, but it is self contained.  It would be nice to have a
package setup like TeXLive, but I have seen the discussions about the
challenges involved.

Booting Grub2 on F17

[Jim]

Fedora 17

This is a dual boot computer Fedora and Windows 7

How would I edit /boot/grub2/grub.cfg to get the the boot process to 
stop at the Menu to be able to select Fedora or Windows7.


I do not want to have to hit "Return" or "Tab" to get it to stop at the 
Selection Menu.
A new User to Linux will be operating this computer and I do not want to 
put him in a position to have to hit extra keys, to make his selection.

Marc, I have to ask why you are doing that as opposed to just creating a VM
and running Fedora in that. It just seems so much easier. And I have friends
running fc17 in VM on both Mac and Windows7, so it's pretty sure Ubuntu
would do so as well.

Just curious why you took that approach.



I have a similar build system for SLC 5.7.  Our software can also be
deployed in a VM; I have tried that but found the overhead of using a VM
(build times, test job run times and the fact that you have to have a
working virtualisation setup) rather large.  Instead now I (and many of
my colleagues) use a few scripts to maintain the chroot system for our
software.  This also seems easier to implement across multiple linux
distros without much fiddling (it's after all a few scripts that uses
chroot to setup the environment).  To give you an idea about the "easy
on various" distros bit, we have tried this on Arch, Ubuntu, Fedora and
Debian.  Getting it to work on Fedora required some extra effort to get
the SELinux labels for the chroot'ed directory hierarchy correct.

Your last sentence sums up some of the issues I hit with chroot, but I'm glad it 
works well enough for your needs. I don't like to worry about the build options 
of the kernel I run vs. the environment of another distribution, so I went the 
VM route using a raw disk image. It runs on either of my home hosting machines, 
or my laptop in a pinch, and at least the MINT VM I built for testing reportedly 
runs under Mac VM, whatever comes with Windows7, and VMware (I think on VISTA).


Whatever works for you, either way will work, but I don't want to ever find out 
that an update to SElinux changed behavior, or glibc was patched to a "more 
correct" but non-working state. The right solution is the one which uses the 
least of your time in this case.

Installing MATE

[Bill Davidsen]

I got some questions about MATE and wanted to install it and actually see how it 
worked. I started with a machine on fc17, which had Cinnamon and XFCE installed. 
After doing the yum install, I don't see MATE in the list of managers available 
at login. Before I spend a lot of time in documentation, it this normal? Does it 
not drop in like KDE, etc?

MATE is not currently in the Fedora repositories.

To install, follow the instructions at http://wiki.mate-desktop.org/download  
  Which are...

yum install 
https://dl.dropbox.com/u/49862637/Mate-desktop/mate-desktop-fedora-updates/16/noarch/mate-desktop-release-16-6.fc16.noarch.rpm

yum groupinstall MATE-Desktop

FYI http://fedoraproject.org/wiki/Features/MATE-Desktop  contains the 
status for inclusion of MATE in F18.

set root=(hd0,msdos1)

will often do the thing, may need to change the numbers.  These are
often hidden inside a
grub2 find statement.
This sets the boot partition, and names used in the "linux" kernel;
specification are given
in realation to this root.

Then in the "linux" kernel line, the root=/dev/sd?? is used to set the
system root.

linux vmlinxuz- ro root=/dev/sda3 []*

I erred in giving you the instructions for F16  So, just replace 6 with 7 
or go to their instructions.  :-)
