![]() ![]() Since after disabling most of us are able to work fine. There was one system which even after disabling firewall was stuck at directory listing, this might be an issue within that system or the connections are being blocked by an external factor. I checked the same on my end after creating the firewall rule, issues were resolved. We disabled the firewall and the everything started working as expected. We checked why the 'dir' command is not working from the devices after the successful authentication, we got to see that the windows firewall is blocking the connection. I tried testing with WinSCP and FileZilla and got to see Passive mode connections are working fine and Active not which is an expected behavior. Also while initiating connection to 11.22.33.44 from Commad promt the session freezes after you give 'dir' command however the same is working with other ftp clients like FileZilla and Winscp. We were unable to see that the Passive mode works here. Initially, We also found that the FTP connections to 11.22.33.44 was working fine and these connections were Active connections. However, the DNS was resolving to the secondary FTP IP instead of Primary IP addresses 11.22.33.44 and 44.33.22.11 are both configured on the same Machine. Trying to initiate a connection to which was resolving to 11.22.33.44 and not to the actual FTP Server 44.33.22.11 ![]() We found that the ftp connection is not working from the command prompt. (we configure primary IP and secondary IP on the server) The packet capture doesn’t states weather is it passive or active mode and source IP is correct. Installed Wireshark on server and on my laptop to capture packetsĬreated a filter on wireshark with “ftp” and “IP” 7 opened on by Caenhorn 2 no winding sound in v 1. 9 opened on by easior 1 Chocolatey package 8 opened on by jnm2 Timer window not showing if taskbar is positioned on the left side of screen. We are able to connect with testuser but not able see the directory/List tomighty-windows-1.0.0.0-beta04 can't run on win7. Issue: Client cannot connect to ftp from command line and Powershell Most other support passive mode.įor example WinSCP defaults to passive mode and there's a guide available for converting Windows FTP script to WinSCP script. Use any other Windows FTP command-line client instead. Unfortunately Windows FTP command-line client (the ftp.exe) does not support passive mode at all. If possible, you should use a passive mode as it typically requires no additional setup on a client-side. See my article Network Configuration for Active Mode. Or your client is not aware of its external IP address and provides an internal address instead to the server (in PORT command), which the server is obviously not able to use. It's likely because of your local firewall or NAT that the server was not able to connect back to your client to establish data transfer connection for the directory listing ( ls or dir commands). Setting up the FTP in the active mode can be cumbersome nowadays due to firewalls and NATs. Windows FTP command-line client ftp.exe supports an active FTP mode only. ![]()
