Why proxy-chains doesn't works ? Is there any full proof mathos to use local proxy on Linux ?
by Navdeep Singh Sidhu
Hello friends,
I'm kinda in a trouble right now. I'm using internet behind my university's
firewall & there is a client management software (Cyberroam's Corporate
Client )is installed on our Internet system through which we access
internet. They have blocked many sites like packages.medibuntu.com & other
many sites like social networking sites. Actually i can access all these
sites using proxifier on windows using a local proxy & open port. But on
Linux i have no luck , i have tried all the methods like firefox proxy
setting, fedora's network proxy setting & even proxy chains. But still no
progress. Only tor is a successful way to access all these sites but it
gives poor perfomance with our network config. in comparision with
proxifier on windows. By using local proxy i can bypass speed limits also.
By the way this proxy is https proxy on proxifier but i can't find https
setting in proxy chain. Now i want to use this local proxy on Linux. Is
there any possible way to use it ?
Regards,
Navdeep Singh

by Mickey
f17/kde
Libreoffice-writer-3.5.6.2-2 will print the header line in a document.
I have gone through the LibreOffice-Writer settings and can find nothing
that would cause this Header Line to be printed on a document.
I have even uninstalled LibreOffice and reinstalled to no avail.
Any Ideals ?

hdmi and sound to a tv on F16
by Gregory P. Ennis
Everyone,
I have an HP Pavilion g7-1117cl Notebook PC with F16-x64 as the os. I
have finally had the time to debug the TV interface with an hdmi
connection. I had F15 on this same unit, and was able to have both
sound and video via the hdmi interface. The F16 install was not an
upgrade, but rather a new install.
I had difficulty synchronizing the screen resolution, but solved that
problem with the installation of :
Installed: akmod-catalyst-12.4-4.fc16.x86_64
Installed: xorg-x11-drv-catalyst-libs-12.4-1.fc16.x86_64
Installed: xorg-x11-drv-catalyst-12.4-1.fc16.x86_64
I am still unable to get the sound activated through the hdmi
interface.
Any help you can give me would be appreciated. I am loosing a love war
with my wife who plugged the hdmi cable into her MS Windows 7 machine
and it worked immediately.

Understanding my network
by Arthur Dent
Hello all,
I am part-way through a bare-metal rebuild of my small home server (it
was F15, I am rebuilding as F17). This machine serves up my IMAP mail
with Dovecot and Squirrelmail and hosts my small (mainly static)
website.
The machine in question sits on my home network at 192.168.2.2. I have
opened port 993 on the firewall. I have a domain name (let's call it
example.org) with dyndns.org which points to my IP address (let's call
that 123.456.789.123) and my router forwards port 993 to 192.168.2.2.
So here's the thing - and I don't remember having this problem with F15
(or previous):
I can access my mail using a client on another machine in my network if
I configure it to use 192.168.2.2, but for my mobile devices I configure
the email client to point to example.org. If I am outside of my network
they can access mail fine, but if I am at home and they are connecting
via my own wi-fi... no joy...
The same by the way is true of SSH. Although I use a non-standard port
for SSH the principle is the same.
I have obviously messed up or missed out some configuration step, but I
can't understand where I have gone wrong.
Can anyone help me to fix this?
Thanks

Locking the screen with ctrl+alt+l
by Joachim Backes
Hi, having since some days (??) from time to time the following problem
on my fully updated F17:
If I lock the screen with ctrl+alt+l, it becomes dark (that's OK), but
since some days from time to time, the "darkness" disappears, and I see
the prompt for releasing the screen (as if somebody moves or clicks the
mouse).
But I'm sure that nobody is touching or moving the mouse, and there's no
earthquake ;-)
Anybody sees this too?
Kind regards

Guys, consider something for a moment. There are CERT advisories against
Linux (and most anything else) from time to time. Now, how were these
discovered? Was it experts pouring over the code, was it somebody got
cracked, discovered it, and reported it, or was it somebody noticed some
odd packets and analyzed the vulnerability they were designed to exploit?
Only one of those cases involves a Linux machine that was not cracked.
The rest mean a vulnerability has been found one way or another and
subsequently exploited or at least attempted in the wild.
Deploying more than a minimalist defense gives you a better chance of
not owning the first few systems that get exploited before the hole is
plugged. Even if the chances are one in a million you'll face an exploit
there if every person in Los Angeles owned a Linux machine that means
several people in Los Angeles would suffer a bad case of computer flu.
I have a "thing" about people who say you don't need an AV or other
defense with Linux, "It's safe." That's been a mantra of the know
nothings for nearly 20 years now. I've disagreed with it for nearly 20
years now. So when this juxtaposition of an attempted exploit coupled
with an advertisement on the site from which the attack took place
touting Fedora it sort of amused me leading me to share my amusement
with the list.
(And, as noted, passwords are the easiest hole to exploit on Linux if
the person leaves an SSH port "too open to the world." Thank heavens
for my iptables defensive trick. Only two people have figured out how
they can get more than one shot at logging into my system. And those I
found before they'd had even 100 tries. I locked out their entire
domain with a hard lock instead of the soft lockout that happens
automatically. And I STILL worry. I am paranoid, perhaps. "They"
certainly are out to get me. But it's not personal. They are out
to get anybody they can.)

Isn't it the infamous balance between "safe" and "usable"?
"they" made windows installable for ordinary end-lusers, and applications so they can do funny things in case something goes wrong. And script-kiddies and alike are using all that available power against users.
Until recently, people who were able to do a decent installation of Linux were wise enough to know a thing or two about security, and what to do when you are exposing ports (ssh, mail, sip) to the bad outside world.
Nowadays, you come across distro's (no, I don't name them) that give a you a single-click install.
The fact that you do not see malicious viruses targeted at Linux systems that often give them a false sense of security.

Kernel Logging
by Marvin Kosmal
Hi...
Hoping to get some help with my Ubuntu upgrade. I know this is NOT
the Ubuntu list but, you guys are smart.
I just upgraded from 10.4 to 12.4.
And my Kernel logging stopped.
I have Googled and looked around and I am guessing I am using Upstart.
Not Klogd or syslogd.
Any help would be appreciated.
TIA

Default web browser
by Suvayu Ali
Hello eveyone,
I have a weird problem; I have both Firefox and Google Chrome installed
and Firefox is my default browser. However for some reason html files
are always opened in Google Chrome when opened with exo-open or
xdg-open.
$ xdg-settings get default-web-browser
firefox.desktop
$ exo-open --launch WebBrowser # this opens Firefox
However,
$ exo-open /path/to/local/file.html
$ xdg-open /path/to/local/file.html
opens /path/to/local/file.html in Google Chrome.
Any ideas?

Joe, thanks for that "startxfce4", it completely changed what i was getting
for the graphical display, now clearly in XFCE.
So that is a big advance for me.
I am still stuck on the reboot forcing me to go to console and "startxfce4".
The boot process looks really barren, with a single blue-white bar
with "fedora 16" in blue at far right,
at the bottom of a black screen.
Possibly this problem caused by cruft from the preupgrade,
run from f14, which itself is a preupgrade from f12.
Or, I did something weird during the preupgrade.
