Changing your hosts file in Vista

By default, if you try to modify your hosts file in windows Vista, it will not let you save it. It tells you that you don't have permission. To successfully modify the hosts file, run notepad.exe as an administrator open the file. This is a windows vista and windows 7 issue and does not need to run in windows XP

1 ) Browse to Start -> All Programs -> Accessories
2 ) Right click "Notepad" and select "Run as administrator"
3 ) Click "Continue" on the UAC prompt
4 ) Click File -> Open
5 ) Browse to "C:\Windows\System32\Drivers\etc"
6 ) Change the file filter drop down box from "Text Documents (*.txt)" to "All Files (*.*)"
7 ) Select "hosts" and click "Open"
8 ) Make the needed changes and close Notepad. Save when prompted.

Here is a sample of what the hosts file looks like
I added 3 banner sites at the bottom as an example of what you can add.
In this example, everytime your browser tries to go to or
your computer will answer with nothing... which causes no banners to come up!

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

mod_wsgi apache freebsd python

The version of Apache on older versions of FreeBSD is not compiled with support for multithreading but Python itself is. Normally this would be where Apache 1.3 is being used. The result is that when starting up Apache with mod_wsgi, an error similar to the following can occur:

Syntax error on line 37 of /usr/local/apache2/conf/httpd.conf: \
Cannot load /usr/local/apache2/modules/ into server: \
/usr/local/apache2/modules/ Undefined symbol \

You may also get this Error with apache 1.3

Syntax error on line 244 of /usr/local/etc/apache/httpd.conf:
Cannot load /usr/local/libexec/apache/ into server: \
/usr/local/lib/ Undefined symbol "pthread_attr_destroy"

The solution is to force Apache to preload the reentrant version of the C runtime library which contains the POSIX thread library functions. This can be done by modifying the 'envvars' script, if it exists and is used, contained in the same directory as where the Apache 'httpd' binary is installed, or the Apache startup script, and add the lines:


Step 1.

Set the library to system environment.

# LD_PRELOAD=/usr/lib/
# export LD_PRELOAD

Step 2.

Stop apache then start it up again

[email protected] rc.d # ./apache stop
Stopping apache.
Waiting for PIDS: 35117.

[email protected] rc.d # ./apache start
Starting apache.

sqlite error trac install

While trying to install trac on freebsd 7.0 I had an error with sqlite.
The problem was that I had an old version already installed, but the system didn't tell me that!

# cd /usr/ports/www/trac
# make install clean

Installed /usr/local/lib/python2.5/site-packages/pytz-2009r-py2.5.egg

I thought to myself, maybe I need to update the system.

# cvsup -g -L 2 /root/cvs-supfile

# make install clean

That did nothing, I get this same error. Maybe if I install it manually

cd /usr/ports/databases/py-sqlite3

[email protected] py-sqlite3 # make install clean

*** Error code 1

Stop in /usr/ports/databases/py-sqlite3.

that didn't work either, so I tried

# pkg_add -R sqlite3

But the ftp server was wrong to get the correct port...

for sh you type in

for bash you update the ftp location by typing

# pkg_add -r trac

That worked but this is where the Error shows me I have an old version of sqlite already installed!

Fetching Done.
pkg_add: warning: package 'py26-sqlite3-2.6.4_1' requires 'sqlite3-3.6.19', but 'sqlite3-3.5.6' is installed

so I upgrade my port that I do have.
# /usr/local/sbin/portupgrade -R sqlite3

[email protected] sqlite3 # cd /usr/ports/www/trac
[email protected] trac # make install clean

mysql replication error

MySQL replication broke after a server crash. When trying to start it backup this error shows up.

100303 10:09:54 [ERROR] Slave: Query caused different errors on master and slave. Error on master: 'Invalid error code' (126), Error on slave: 'no error' (0). Default database: 'db_name'. Query: 'INSERT DELAYED INTO stats (clientID, date_accessed, current_url, referred_by, unique_id)
VALUES (0, now(), '/index.php', '', '076c47a32066f611d60e107b3c6be475')', Error_code: 0
100303 10:09:54 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'mysql-bin.000463' position 207592

After a little searching, in order to fix the problem I just have to repair the table with the following command.

mysql> repair table stats;

In my case the query is fine, the reason why it is failing may be
index file is crashed or file format is wrong. Here is a list of error codes that may be helpful to other people.
126 = Index file is crashed / Wrong file format
127 = Record-file is crashed
132 = Old database file
134 = Record was already deleted (or record file crashed)
135 = No more room in record file
136 = No more room in index file
141 = Duplicate unique key or constraint on write or update
144 = Table is crashed and last repair failed
145 = Table was marked as crashed and should be repaired
28 = You ran out of disk space. Delete unnecesary files, or move the MySQL data files to another partition.
1045: Access denied for user: = You forgot to specify a password, or you used the wrong one. Use the -u and -p options when starting the client. (use mysql --help to see how)
1046: No Database Selected = You must use the command USE database_name or the mysql_select_db() function to select a database to use.
1062: Duplicate entry 'x' for key n = You have attempted to insert or update data that would break the integrity of a UNIQUE index (most likely the primary key). You must redefine either the data you're trying to insert, or the indexes which you have imposed on the table.
1064: Syntax error = You wrote something that doesn't match the syntax definitions in the manual. When you have checked everything else, here's something to consider: A common error is to put a space between a function name and its opening parenthesis '('. Another common error is to use a reserved word out of its normal context.
2000: parse error near ... = see explanation for 1064: Syntax error
2002: Can't connect to local MySQL server = The MySQL socket file (usually, /tmp/mysql.sock) is missing. See the notes on connecting to the server.
