If you’re like me and recently upgraded to Verizon FiOS and you have your PS3 on the wired segment and the Media Server (such as PS3 Media Server, TVersity, etc.) on the wireless segment, you’re in for a ride with the configuration.
By default, you can’t route the traffic between the wired and wireless segments over UDP! You can send ICMP echo packets (i.e., ping) but the PS3 just won’t detect the Media server. You may disable the Host-based firewall (e.g., Norton, Kaspersky, McAfee, etc.) but it still won’t work.

If you happen to read posts like these, you will see that you have to disable “IGMP proxy”. IGMP Proxy basically reduces the traffic on the multicast addresses to a bare minimum. Unfortunately for you, this causes the traffic between PS3 Media Server and PS3 to drop.

So you log into your FiOS router’s administration console typically located at 192.168.1.1. Click on Advanced -> Yes -> Firmware Upgrade and check the firmware version. You will see that it is an ActionTec router (based on the Auto-update URL). But nowhere do you see the option to update the “IGMP Proxy” settings. That’s because that feature is “hidden” in the latest firmwares.

So you just need to copy/paste the following URL into the browser address bar and you will see the option to disable “IGMP proxy”.

http://192.168.1.1/index.cgi?active_page=6059

Disable it and Voila! The PS3 Media Server and PS3 can now talk to each other.

While compiling socat-2.0.0-b5 on cygwin (Windows) I got a few errors and here’s how I fixed it:
xioopts.c: In function 'applyopts_single':
xioopts.c:3998: error: 'struct single' has no member named 'fd1'
xioopts.c:4000: error: 'struct single' has no member named 'fd1'
make[1]: *** [xioopts.o] Error 1
Edit the file xioopts.c in your favorite editor and replace ‘fd1′ by ‘rfd’ in both lines (3998 & 4000). That fixed this error but then I got my next error.

xio-ip.c:480: error: structure has no member named `ipi_spec_dst'
Edit xio-ip.c and comment out the entire snprintf statement in xio-ip.c line 480.

Continue compilation and it should now work fine.

I was getting CUPSD errors when trying to use my Laser Brother HL 2040 printer. But, you can install Brother HL-2040 by going to the brother website and downloading the linux drivers located here:

http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html#HL-2040

I just installed the lpd driver using the command as follows:
$ sudo dpkg -i brhl2070nlpr-2.0.1-1.i386.deb
When printing now, just select local lpd and then select brother-HL2070 printer from the list (the drivers for both versions are same).

Over this weekend I decided to download the Android source tree on my computer (Backtrack 4 R2). The BT4R2 is no longer supported by the Offsec/Backtrack guys (mutt, purehate, etc.).
To start off with I tried to follow the instructions listed here.
The first error I got was with Git, I was using a version earlier than 1.5.4. So I downloaded git version 1.7.4, compiled it and installed it. Then I got the error:
fatal: unable to find remote handler for 'https'
Too bad, I tried recompiling and what not, and I did have openssl…so what was the problem?
The problem was not having libcurl-devel library. So I downloaded the library and launched configure, make clean, make and make install to reinstall git. Now the error was gone.

On the step where I am supposed to execute the following:
$ repo init -u https://android.googlesource.com/platform/manifest
I got the following error:

error: Exited sync due to fetch errors


Seems like this error is caused because the content-length http header is not sent by the repository. If you upgrade to Python 2.7.x you can resolve this error.
Now if you are compiling Python from source, it doesn’t come by default with SSL support. So to add SSL support you should edit the Python-2.7/Modules/Setup file and uncomment four lines:
_socket socketmodule.c
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
Of course, then you can do the standard steps to compile and install python:
$ ./configure
$ make
$ sudo make install

repo sync would work very well thereafter.

I kept getting the following errors on my AD domain in the event viewer and accounts kept locking out:
Pre-authentication failed:

In the Directory Service logs I see the following entry:
[snip]
Active Directory could not update the following object with changes
received from the domain controller at the following network address
because Active Directory was busy processing information.

Turns out this happens if you have samba/winbind/AD type infrastructure. If someone has some processes running (Even if they us sudo) and happen to change their password while the process is running on unix (and using kerberos authentication), the accounts lockout because the kerberos ticket granting ticket (krbtgt) is not current and any object access is considered to be a failed login attempt. This locks out the accounts if you have account lockout implemented in your AD domain security policy.
