EDUP Realtek Semicondutor Corp. RTL8192CU/RTL8188CU 802.11n WLAN

2013-08-10T03:51:00.000+01:00

Using a cheap usb wifi dongle EDUP on Fedora.

For newer kernel versions (3.+) there is included the module rtl8192cu which activates the device and allows to detect the wireless networks, but I couldn't connect to any network despite no visible error occurred.

Instead, since I got it, I've used the official driver from realtek. One just needed to be aware to blacklist rtl8192cu:

echo 'blacklist rtl8192cu' >> /etc/modprobe.d/blacklist.conf

To install the driver just unzip the contents and on a terminal

sh install.sh

Enter the sudo password whenever it is prompted.

However since kernel 3.7+ I couldn't compile the driver because some functions cease to exist on the newer kernels versions, and so I was stuck to keep my older kernel.

Fortunately some awesome person ported it and shared with everyone:

git clone https://github.com/dz0ny/rt8192cu.git
cd rt8192cu
make
sudo make install

Possible errors

compiling driver error
osdep_service.h:575:2: error: implicit declaration of function "daemonize"
possible to comment out the daemonize call in osdep_service.h, though the driver will compile will get an error when trying to load it

loading module error
8192cu: Unknown symbol kernel_thread (err 0)
This could occur if using a module compiled for a different kernel (3.6-) or if compiled without properly porting the driver to kernel 3.7+

Use the ported module, tested on kernel 3.9.10-100.fc17
Another mirror to the ported driver : rt8192cu.tar.gz

dovecot+ispconfig - authenticate user with alias domain

2012-06-20T13:55:00.001+01:00

For anyone using ispconfig3 with dovecot ( imap/pop server), the default auth mechanism only allows the user to authenticate with e-mails from the main domain.

If one domain is @domain.com and we configure @domain.pt to be an alias of the first one, we can only login with:

username: user@domain.com
passwd: *******

To allow the login to be made with user@domain.pt, we have to change the query made by dovecot. Just replace the user_query and password_query in dovecot-sql.conf:

user_query = SELECT email as user, maildir as home, CONCAT('maildir:', maildir, '/Maildir') as mail, uid, gid, CONCAT('*:storage=', quota, 'B') AS quota_rule, CONCAT(maildir, '/.sieve') as sieve FROM mail_user WHERE disable%Ls = 'n' AND (email = '%u' OR email = CONCAT ( SUBSTRING_INDEX('%u', '@', 1), (select mail_forwarding.destination FROM mail_forwarding where source = CONCAT ('@',  SUBSTRING_INDEX('%u', '@', -1)))))

password_query = SELECT password FROM mail_user WHERE disable%Ls = 'n' AND ( email = '%u' OR email = CONCAT ( SUBSTRING_INDEX('%u', '@', 1),(select mail_forwarding.destination FROM mail_forwarding where source = CONCAT ('@',  SUBSTRING_INDEX('%u','@', -1)))))

Twinkle: USB Headset Microphone (Fedora/Linux)

2010-12-09T16:17:00.003+00:00

My usb heaset (Halfmman Cobra HS-87, which are the same as the ozone oxid) worked perfectly in my Fedora Core 13 (2.6.34.7-63.fc13.x86_64) KDE 4.5.3, both output(speakers) as well as the input(microphone). That was until I've tried to use it with twinkle.
Didn't have any problems getting it to work in skype, just plugged it in and it was automatically detected and added to the system.
Went to System Settings -> Multimedia -> Phono and could see it there. Gave it higher priority over the other devices, and after that it worked perfectly in my system.

The problem appeared when I tried to use it in twinkle, though I could ear perfectly, it wasn't using my headset's microphone, instead it was using my laptop's.

Since I use pulse audio (default in Fedora) I noticed that twinkle uses directly alsa. So after a litle search (not so little) I came across this thread, and it saved me =)

Since I only needed the micro to work, I created the following .asoundrc in my home directory:


pcm.usb_in {
        type pulse
        device alsa_input.usb-04d9_0020_832R-00-U0x4d90x20.analog-mono
        hint {
                description "halfmman Cobra Micro"
        }
}

To find the device value use:
pactl list
And search for the device you want, which in my case was: alsa_input.usb-04d9_0020_832R-00-U0x4d90x20.analog-mono.

After that open twinkle -> Edit -> System Settings -> Audio

On the Microphone select ALSA: other device
and on the other device field put: usb_in

It should be working now!

kde - network manger plasmoid and wpa-wpa2

2010-08-05T11:24:00.005+01:00

I had a problem connecting to my enterprise wireless network. They use WPA-WPA2 Enterprise with TTLS authentication and PAP as inner authentication.

I use the plasma widget of network manager, running on kubuntu 10.04

I figured it was a problem with reading/parsing the certificate file, from my syslog i got this message:


Aug  5 10:31:46 namikaze wpa_supplicant[848]: OpenSSL: tls_connection_ca_cert - Failed to parse ca_cert_blob error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag

I got on-line...with other means =)

and got to this bug report:

Bug 209673 - knetworkmanager applet (NOT THE PLASMOID) can't connect to WPA PEAP when validating by CA certificate

Well...they do say it's not related to the plasmoid...but i figured it should be similar...

They say it has something to do with network manager not feeding the certificate to the wpa_supplicant in the correct form/way (comment #21).

I've tried their workaround (comment #25)...well i failed...

~ #cat cacert.pem | grep -v "CERTIFICATE" | base64 -d > cacert.dem
base64: dados de entrada inválidos

so I thought to use openssl to convert the certificate to dem:

openssl x509 -in cacert.pem -outform der > cacert.dem

...and that did work!

I've just changed the configuration of the network...to point to the new certificate....and that actually did the trick =)

After adding a new group to user, getent showed user on the group, but wbinfo -r user, didn't:

# wbinfo -a [domain\\]user%password

then

# wbinfo -r user

it should now print all the same groups as getent

SpeedTouch - modem vulnerability

2009-10-01T18:32:00.003+01:00

Something I just found out:

How to access to a SpeedTouch Administration Web Page!

You need to have access to one speedtouch web administration page.
Once you access it through you web browser just exit or, don't exit at all, without logging out. that is the important part.
After that you have to access the network where the other speedtouch is in, and which you want to access and don't know the password. Just type de web adminstration url and you're in.

Some notes:

this is probably because of a cookie validation that is not being done
just tested on 2 different speedtouch
used the url: http://speedtouch.lan for this

Poledit - Screen Saver template

2009-07-01T15:49:00.003+01:00

This is a template created to use with poledit.exe which allows one to define in a policy the screen saver options.

- activating it
- prompt for password
- idle time
The idle time is pre-defined as 5 min., to change just edit the template, which is pretty much self explanatory.

VMWare 2.0.x web interface - remote console access

2009-06-26T10:29:00.003+01:00

Problem:
Unable to connect to the MKS: Cannot connect to host localhost: Connection refused.

In order to use the the console provided in VMWare's web interface using an ssh tunnel, one needs to forward both port 8333 (web interface) and 902 (authentication daemon), assuming your using the default ports. Also note that you'll need to forward them as root, since they are privileged ports.
Example:

~# ssh _host_on_same_network_ -L 8333:vmware_host:8333 -L902:vmware_host:902

Then fire up your browser and access https://localhost:8333 and now you can freely use the console.
