PASV problem

Kyle D. Harris — Fri, 12 Dec 2003 09:33:30 GMT

ftp> put /home/openssh-3.7p1-1.i386.rpm
local: /home/openssh-3.7p1-1.i386.rpm remote: /home/openssh-3.7p1-1.i386.rpm
200 PORT command successful. Consider using PASV.
553 Could not create file.

I'm simply trying to put a file from one server to another and i get the above "could not create file error"... I'm not sure why. Thanks for the help.

Hello,

usually because there is a firewall between the two systems which does not allow you do open the (high numbered) port for the data connection. Follow the suggestion to switch to
passive mode, which was implemented to circumvent this problem.

In my ftp client the command to do this is passive on.

The other obvious possibility is that the user you use to connect with is not allowed to create the new file in /home (which would make sense since /home is not a normal user
directory)
Greetings, Martin

I'd first look at your iptables or ipchains firewall configuration and see if its messing with the transfer.

service iptables stop
or
serivice ipchains stop

try again.

Also, check permissions for the user on the target system.

Sometimes if the user name is the same but the numeric user id is different, the target server gets confused as well.

from ftp prompt just type the following

ftp> passive
Passive mode off.
ftp> passive
Passive mode on.

as you can see this will toggel passive on off

ftp> status
Not connected.
No proxy connection.
Mode: ; Type: ; Form: ; Structure:

ftp> quit
