Why does WinSCP/F-Secure error/hang after successfully logging in? F-Secure gives the following error: "File transfer server could not be started or it exited unexpectedly. Exit value 0 was returned." WinSCP: "Recieved too large SFTP packet. Max supported packet size is XXXXX bytes. This error is typically caused by message printed from startup script (like .profile). This message may start with..."

Adding certain lockers or running certain programs at login time by changing your UNIX dotfiles (.mycshrc, .cshrc, and .login) can cause SFTP/SCP programs to error/hang.

For example, if the .cshrc file looks like

alias ld 'll | grep "^d" '
# display calender

Remove the lines for cal . Any program which is specified to run on login causes the sftp file transfer to exit abruptly.
