ghostdog, i'm actually being a client for this one server.
what i do is to telnet a server, then from there i go into ftp server to do downloading certain files. in order to go into the ftp server and thus do downloading, i usually run a prepared script saved in ftp client. again, my command line is sumthing like below:
telnet XXX.XXXX.XXXX.XXXX [ip address of server]
script.sh
usually, files will appear in the ftp client and i can download it into my pc.
but now, what happened was that i couldnt even run the script as error saying "permission denied" appears.
hopefully u can get what i mean.
