are you speaking about good ftp server or about secure ftp protocol?

In first case I can recommend vsftpd (default in RH9), in second - you can use ssh suite.

Hi,

openssh has support for sftp-server module enabled by default. For sftp-server to accept connections , sshd daemon should be running.

Load openssh in two unix servers and from one server ( server A )issue this command.

#sftp user@serverB

supply the password. Now a ssh connection is established and a normal ftp command line interface will be seen thru which you can give essential ftp commands. complete connection channel is encrypted.

If the files to be transfered are bulk in size then the sftping will put more load on cpu resources on both the servers bcoz of overhead caused by encryption and decryption for bulk data at both ends.

U.SivaKumar

Dear worapoj,

What is the length of password for that user ?.Try reducing the length of the password.

winscp is a GPL licensed free software for windows to use sftp and scp
