The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

-= SSH and FTP =- HELP NEEDED - !!!

Asked by moe10 in Unix Network Security

Tags: , , ,

I am useing SSH Client and i have two accounts on two different UNIX SSH servers.  These servers are named:

  sparc.nic.bc.ca

and

  cs2.nic.bc.ca

From one account i would like to form a ftp connection to the other useing a SSH tunnel. This is the command i use to start the connection from sparc.nic.bc.ca to the second server, cs2.nic.bc.ca:

  ssh -f -L 4321:cs2.nic.bc.ca:21 cs2.nic.bc.ca sleep 20

and this is the command i use to start the ftp connection:

  ftp localhost 4321

I can then use the "status" command and verify that i am connected. however, if i try to do a simple directory listing with the "ls" command i get this error message:

ftp> ls
500 'EPSV': command not understood.
Passive mode refused. Try EPRT500 'EPRT |2|::1|35665|': command not understood.
500 'LPRT 6,16,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,2,139,81': command not understood.
425 Can't build data connection: Connection refused.

Why would i be getting this error message? and how would i solve this problem?

I have read many posts stating that i should enter the "passive" command while within the ftp connection, but this does not work because it does not seem to recognize the "passive" command.

I have tried createing .shosts files on both of my accounts on those servers, but that does not seem to help.

Does anyone know what i'm doing wrong?
