FTP: connection speed – F-E and exponent

by admin on Oct.25, 2008, under FTP

 

This post is a little off topic from what I normally post on this site. But I believe it will be very helpful to some of the techie people online.

Recently I was doing some FTP connection speed test to check my ISP upstream. The results were as follows

28463104 bytes sent in 49 seconds (5.7e+02 Kbytes/s)

what in the heck is 5.7e+02 i said. I have been out of school for some time now and forgot all about power of formulas. so this post my help someone that ran into the same issue as myself.

5.7e is a scientific calculation of 5.7, +02 means add 2 zero and move the decimal point over to the right which will convert 570.0 but you can drop off the last zero which means 570Kb .
You will see this statement when using the FTP client in dos or linux mostly .

 

Step Action Calculator display
1 Make sure the Windows calculator is in Scientific mode by selecting Scientific from the View menu. 0.
2 Enter 3. 3.
3 Click the Exp button which you will find in the left half of the calculator keyboard. (‘Exp’ stands for ‘exponent’.) This tells the calculator that the next number you enter will be a power of 10 and that you are working in scientific notation. The ‘e’ now showing on the display indicates that the number you have entered is displayed in scientific notation. 3.e + 0
4 Enter 4. The display is now showing the equivalent of 3×104.You have now finished entering the term in the first set of brackets. 3.e + 4
5 Click the multiply (*) button. This tells the calculator that you want to multiply the number showing in the display by some other number. The display now changes to show the number you have entered in its full form (3×104= 30000). 30000.
6 You will now start to enter the term in the second set of brackets. Enter 2. 2.
7 Click the Exp button. 2.e+0
8 Enter 3. The display is now showing the equivalent of 2×103. You have now finished entering the term in the second set of brackets. 2.e+3
9 Click the equal (=) button. This tells the calculator that you want it to display the result of the calculation. This is shown in its full form. 60000000.
10 Finally, you can force the calculator to display the result of the calculation in scientific notation. Do this by clicking the F-E button which you will find in the left half of the calculator keyboard. (‘F-E’ stands for ‘fixed to exponent’) The display is now showing the result in the ‘shorthand’ form which you can interpret as 6×107

ftp error 553 Requested action not taken. File name not allowed.

by admin on Dec.06, 2007, under FTP

it basically means the user does not have write permissions to directory your viewing .

on linux you would want to login into ssh with superuser .. and change the ownership of the diretory

chown uer | directory

take out the | when using the above syntax
