Currently researching changes in tuning, if any.

Which is ok, if it’s seeded correctly, but I’ll be damned if I am going sit around waiting for a 700MB download at 8k a second when I’m sitting on a 7Mb connect.

I’d love to try it, but screw that.

Everything is back up and running.

One database was corrupted but we were able restore it from this morning’s backup.
Backups will be more frequent during storm season.

7. Repeat step #5
8. lvreduce -LxxG /dev/VolGroup00/LogVol00
Note: “-LxxG” is the same value as xxG in step #6 in this case.

9. Repeat step #5
10. Remove CD and reboot
11. vgdisplay -v | less
12. vgs
13. lvs
14. Create new LV’s to re-use space

(FIXED)1. Text – Links Too dark. The gray is a couple shades too dark for it’s background color.

(FIXED)2. Text – Black text, in text entry areas, is too dark. (search box)

(FIXED)3. Spacing – Spacing on articles and blocks.
There needs to be a CR between the controls of an article teaser and the title of the next.
In blocks, there needs to be a CR at the end.

(MOSTLY)4. Preview – white text on white background. Mostly fixed. You can now see the body but some fields, like author, still have some white text on white background. Comment preview works fine however.

(FIXED)5. Bottom AdSense block not showing properly. (Apparently main page only)

(FIXED)6. Pager black text too dark.

CIALUG, the local linux users group, suggested using firebug to find these issues.

Don’t get me wrong, I’ve had them get loud. Loud to the point I have replaced them to maintain sanity but I’ve never had one report bad sectors… Until now.

I guess I’ve been lucky.

I’ve been having some reliability issues with my firewall and I think I’ve finally traced it down to the hard drive heading south for the winter.

It’s been a rock solid drive. I really like the Barracudas from Seagate. Enough that I will replace this one with another I have sitting in storage.

1111 days + 22 hours run-time is nothing to sneeze at for a PATA drive.

I recently bought a Nuvi 255W for some business travel coming up. I didn’t want to install Map Source since I don’t plan on buying any map packs any time soon. What I found was Garmin Communicator.

Windows:
Straight forward download and install.

Linux (Ubuntu):
apt-get install wine-gecko
Download Garmin Communicator
Download Firefox for Windows
Use wine to install Firefox and the Communicator plugin

Adding Waypoints:
To add waypoints using Google Maps, run the Windows version of Firefox.
Navigate to Google Maps and search for the location you want to add a waypoint for.
Click the “send” link, you should have a GPS selection now.
Select your GPS Manufacturer, in this case “Garmin”. This will send you to my.garmin.com.
At my.garmin.com, select which GPS you want to add the waypoint to.
Click the “Send to GPS” button.

All done.

List of raw FTP commands
(Warning: this is a technical document, not necessary for most FTP use.)

Note that commands marked with a * are not implemented in a number of FTP servers.

Common commands

* ABOR – abort a file transfer

* DELE – delete a remote file
* LIST – list remote files
* MDTM – return the modification time of a file
* MKD – make a remote directory
* NLST – name list of remote directory
* PASS – send password
* PASV – enter passive mode
* PORT – open a data port
* PWD – print working directory
* QUIT – terminate the connection
* RETR – retrieve a remote file
* RMD – remove a remote directory
* RNFR – rename from
* RNTO – rename to
* SITE – site-specific commands
* SIZE – return the size of a file
* STOR – store a file on the remote host
* TYPE – set transfer type
* USER – send username

Less common commands

* ACCT* – send account information
* APPE – append to a remote file
* CDUP – CWD to the parent of the current directory
* HELP – return help on using the server
* MODE – set transfer mode
* NOOP – do nothing
* REIN* – reinitialize the connection
* STAT – return server status
* STOU – store a file uniquely
* STRU – set file transfer structure
* SYST – return system type

ABOR
Syntax: ABOR

Aborts a file transfer currently in progress.

ACCT*
Syntax: ACCT account-info

This command is used to send account information on systems that require it. Typically sent after a PASS command.

ALLO
Syntax: ALLO size [R max-record-size]

Allocates sufficient storage space to receive a file. If the maximum size of a record also needs to be known, that is sent as a second numeric parameter following a space, the capital letter “R”, and another space.

APPE
Syntax: APPE remote-filename

Append data to the end of a file on the remote host. If the file does not already exist, it is created. This command must be preceded by a PORT or PASV command so that the server knows where to receive data from.

CDUP
Syntax: CDUP

Makes the parent of the current directory be the current directory.

CWD
Syntax: CWD remote-directory

Makes the given directory be the current directory on the remote host.

DELE
Syntax: DELE remote-filename

Deletes the given file on the remote host.

HELP
Syntax: HELP [command]

If a command is given, returns help on that command; otherwise, returns general help for the FTP server (usually a list of supported commands).

LIST
Syntax: LIST [remote-filespec]

If remote-filespec refers to a file, sends information about that file. If remote-filespec refers to a directory, sends information about each file in that directory. remote-filespec defaults to the current directory. This command must be preceded by a PORT or PASV command.

MDTM
Syntax: MDTM remote-filename

Returns the last-modified time of the given file on the remote host in the format “YYYYMMDDhhmmss”: YYYY is the four-digit year, MM is the month from 01 to 12, DD is the day of the month from 01 to 31, hh is the hour from 00 to 23, mm is the minute from 00 to 59, and ss is the second from 00 to 59.

MKD
Syntax: MKD remote-directory

Creates the named directory on the remote host.

MODE
Syntax: MODE mode-character

Sets the transfer mode to one of:

* S – Stream
* B – Block
* C – Compressed

The default mode is Stream.

NLST
Syntax: NLST [remote-directory]

Returns a list of filenames in the given directory (defaulting to the current directory), with no other information. Must be preceded by a PORT or PASV command.

NOOP
Syntax: NOOP

Does nothing except return a response.

PASS
Syntax: PASS password

After sending the USER command, send this command to complete the login process. (Note, however, that an ACCT command may have to be used on some systems.)

PASV
Syntax: PASV

Tells the server to enter “passive mode”. In passive mode, the server will wait for the client to establish a connection with it rather than attempting to connect to a client-specified port. The server will respond with the address of the port it is listening on, with a message like:
227 Entering Passive Mode (a1,a2,a3,a4,p1,p2)
where a1.a2.a3.a4 is the IP address and p1*256+p2 is the port number.

PORT
Syntax: PORT a1,a2,a3,a4,p1,p2

Specifies the host and port to which the server should connect for the next file transfer. This is interpreted as IP address a1.a2.a3.a4, port p1*256+p2.

PWD
Syntax: PWD

Returns the name of the current directory on the remote host.

QUIT
Syntax: QUIT

Terminates the command connection.

REIN*
Syntax: REIN

Reinitializes the command connection – cancels the current user/password/account information. Should be followed by a USER command for another login.

REST
Syntax: REST position

Sets the point at which a file transfer should start; useful for resuming interrupted transfers. For nonstructured files, this is simply a decimal number. This command must immediately precede a data transfer command (RETR or STOR only); i.e. it must come after any PORT or PASV command.

RETR
Syntax: RETR remote-filename

Begins transmission of a file from the remote host. Must be preceded by either a PORT command or a PASV command to indicate where the server should send data.

RMD
Syntax: RMD remote-directory

Deletes the named directory on the remote host.

RNFR
Syntax: RNFR from-filename

Used when renaming a file. Use this command to specify the file to be renamed; follow it with an RNTO command to specify the new name for the file.

RNTO
Syntax: RNTO to-filename

Used when renaming a file. After sending an RNFR command to specify the file to rename, send this command to specify the new name for the file.

SITE*
Syntax: SITE site-specific-command

Executes a site-specific command.

SIZE
Syntax: SIZE remote-filename

Returns the size of the remote file as a decimal number.

STAT
Syntax: STAT [remote-filespec]

If invoked without parameters, returns general status information about the FTP server process. If a parameter is given, acts like the LIST command, except that data is sent over the control connection (no PORT or PASV command is required).

STOR
Syntax: STOR remote-filename

Begins transmission of a file to the remote site. Must be preceded by either a PORT command or a PASV command so the server knows where to accept data from.

STOU
Syntax: STOU

Begins transmission of a file to the remote site; the remote filename will be unique in the current directory. The response from the server will include the filename.

STRU
Syntax: STRU structure-character

Sets the file structure for transfer to one of:

* F – File (no structure)
* R – Record structure
* P – Page structure

The default structure is File.

SYST
Syntax: SYST

Returns a word identifying the system, the word “Type:”, and the default transfer type (as would be set by the TYPE command). For example: UNIX Type: L8

TYPE
Syntax: TYPE type-character [second-type-character]

Sets the type of file to be transferred. type-character can be any of:

* A – ASCII text
* E – EBCDIC text
* I – image (binary data)
* L – local format

For A and E, the second-type-character specifies how the text should be interpreted. It can be:

* N – Non-print (not destined for printing). This is the default if second-type-character is omitted.
* T – Telnet format control (, , etc.)
* C – ASA Carriage Control

For L, the second-type-character specifies the number of bits per byte on the local system, and may not be omitted.

USER
Syntax: USER username

Send this command to begin the login process. username should be a valid username on the system, or “anonymous” to initiate an anonymous login.
