hi,

this doc seems to indicate more patches (if they are not already in the server).

please check and reply if the patches indicated r already in place.

I have checked and patches indicated already installed on my server.

Hi,

What is the o/p of "netstat -an" command? Look out for local address similar to 10.1.81.24.20.

I think port no. 20 is already being used.

[yuli_3]

i just checked with "netstat -an" and o/p is port 20 is not being used.hmm..

[Suraj Singh_1]

WHat is the speed setting of the network card? Check the o/p of 'lanadmin -x '.

Try changing the duplex settings..

I found this suggestion on net..

ls works using passive mode because your firewall restrictions, that mean your network admin is restricting your network to use the same port to send and receive information when you open an ftp session, then you need to include always the passive command or tell to you network admin change the firewall restrictions.
