I just downloaded WinSCP. I’ve tried and tried to get it to connect to the server, but it doesn’t work. I’ve been through the FAQ and all but couldn’t find anything to help. This is the error message that I get:

Timeout detected.

Could not retrieve directory listing

Opening ASCII mode data connection for /bin/ls.

Error listing directory ‘/’.

Can you help me?

I’m not sure what you wanted me to see in the documentation. I’ve uninstalled and re-installed, checked and double checked my settings, host name, passwords, etc., tried both passive and active, and still cannot get through to the server. Here’s the error message I’m getting now:

Could not retrieve directory listing

Can’t open data connection.

It says that it is connected but each time it tries to retrieve the directory it fails. I know that other people are getting through to this server with WinSCP – what is going wrong for me?

Please HELP!

You haven’t posted full log file, so I cannot tell for sure. But from the IP address I suspect this issue is what you are facing.

@Lauri: You cannot fix it. But the problem is tracked already, so it will be resolved eventually.

@Lauri: Are you using PASSIVE (PASV) connection? If so, you’ll need to configure your client accordingly and ensure the proper PASV ports are open on your firewall if you are accessing your FTP server through one. FTP server admin, if other than you, will know the PASSIVE port range.

Hi, this is a bit old however the problem is STILL not solved. It has been getting on my nerves for a while and if there were decent free Windows FTP clients I would have given up on WinSCP a long time ago. Anyway, my rants aside, here is a work around that you might find useful. If you notice, the error message usually suggests that you try passive mode due to inability to open some port. Now there might be any reasons why a port cannot be opened and WinSCP cannot really change that. Nonetheless the software should be able to automatically switch to a passive connection which it currently most definitely does not do.

You have to tick the passive connection box. The way you do this is tick the Advanced options box. Then under Connection tick the passive one. I also selected IPv4 as the internet protocol (might not work in your case) and under Environment > FTP ticked the Force IP … option. I’d suggest you save all that as a session and reuse the setting next time. If you are editing a saved session make sure that you save.

Hope this helps!

Since 4.3 the passive mode is the default one.

Had a problem with this for years.

Forgive my «layman’s» jargon.

Previous dialogues with site Admin & Tech personnel tried to locate a «problem» with my modem. That ceased when exactly the same «problem» arose with a different ADSL2 modem.

Was a problem then with my broadband connection, which used a shared, not dedicated, address at the exchange.

However, the problem was *only* with remote servers run on Microsoft Windows and was dated to a server upgrade ~3.5 years ago.

Other remote servers e.g. Unix didn’t care

Once I changed providers, the problem disappeared altogether.

Until now.

It seems to be a connection speed? issue. I have blown my 2 gigabyte allocation and the transfer speed slows to around 7 kbs.

Logging on to the remote Microsoft Windows FTP server I got no timeout message but:

Could not retrieve directory listing -Can’t open data connection

I deselected passive mode and removed permanent caching and, bingo, got in.

Hope this helps,

Laurie

Re above, deselecting passive mode,

«Auto» is greyed out, but neither IPv4 nor IPv6 are selected.

What’s the story there?

Try disabling passive mode. Probably not all FTP passive ports are not opened.

For example these all ports must be allowed to use passive mode.

This is bit confusing. The numbers in the 227 response are not port numbers! Only the 219 and 190 represent a port number 56254 (219 * 256 + 190). The 202,234,195,227 is an IP address. So there’s only one port number in the message.

Hi All,

This could be caused if the server is in active mode and not in passive mode

Hi,

I am facing this same issue am assuming if it’s because the data channel ports 5000-5005 which i have updated the firewall settings which aren’t open, It connects to the FTP successfully but does not list the folders under the FTP drive created.

Timeout detected. (data connection)

Could not retrieve directory listing

Error listing directory ‘/’.

Appreciate your input in this regard.

Thanks,

Fazil

@Fizzy: Sorry, I do not understand. Can you try to describe your problem again?

Also, can you retrieve the listing using any other FTP client?

After messing around for ages and reading all the useless advice – this is what fixed it for me.

I am using Plesk FTP server with WinSCP connecting on port 21 Passive.

So in Sire settings – Go Advanced > Then FTP under Environment.

Change the following commands that used to be set to AUTO

Use MLSD command — On

Force IP for passive — On

Use HOST command — On

Boom then everything worked.

On a recent case the problem was not the lack of FTP server support for MSLD as log seemed to show cause the connection was lost just after MSLD trying to get the dir listed. The Linux vsftpd server was good:

at file /etc/vsftpd/vsftpd.conf it had both active and passive services OK 

connect_from_port_20=YES
pasv_enable=YES

The issue did not happen all the times, sometimes the connection was established (!)

This was a CentOS 7 policy (SELinux) issue solved by 

setsebool -P ftpd_connect_all_unreserved 1

or just disabling SElinux

By the way old Windows up to version 8 had ftp.exe supporting only active FTP.

For me it was a VPN issue, server was blocking the IP so it was not allowing the directory listing, just check if you something similar kind of setup.

I was trying to connect from USA and server was in India, so may that is why it was blocking for security purpose.

I’m running a FreeDos v1.1 VirtualBox guest on a Windows 7 64-bit host. Today I ran mTCP’s ftpsrv.exe for FTP access and FTP’d into FreeDos using WinSCP. It started me in my last accessed directory, which was /DRIVE_C/RR2. I browsed to the root directory (/DRIVE_C) and uploaded a small file. After the file transfer completed, WinSCP hanged on the file transfer before telling me the connection was broken and that it failed to retrieve the directory listing:

Timeout detected. (data connection)
Could not retrieve directory listing
Error listing directory ‘/DRIVE_C’.

Initially I thought there had been a disk error, but the file was successfully uploaded and everything else seemed to be in order.

Trying to reconnect, however, results in the same error. Clearing the remote directory setting from WinSCP solves nothing. I created a new user and logging in that way still received the same error.

What I can do is manually specify the starting directory to almost any subdirectory other than /DRIVE_C or /DRIVE_C/FDOS. Directories are randomly «not found,» causing WinSCP to disconnect, and WinSCP will randomly choke and disconnect while transferring files. Sometimes I can copy a file in FreeDOS to a different location then download it via FTP, but sometimes not. Uploading a file will usually render its directory invisible to FTP.

The VM has a 2GB disk and is half empty, so the disk isn’t low on space.

After wasting hours trying to troubleshoot this, I finally said «screw it» and installed a FreeDOS 1.2 VM guest. I downloaded as many games files as I could from my FreeDos 1.1 VM, then started uploading them to my new FreeDOS 1.2 VM. I decided to put the game files under /DRIVE_C/GAMES/ and drag-n-dropped them from my host to the guest via WinSCP. WinSCP timed out and resumed a few times before choking on a directory listing error and then quitting with an «abnormal execution» error. I can no longer access /DRIVE_C/GAMES/ via FTP (but have no problem when working directly on the system).

Here’s my ftpsrv user setup on both FreeDOS VMs:

# userid password sandbox_directory incoming_directory permissions
redacted redacted [none]            [any]              all

According to this, my login should have full access with no restrictions.

mTCP configuration on FreeDOS 1.1 (mostly default settings)

packetint 0x60
mtu 1472
DOSRules
ftpsrv_password_file c:FDOSftppass.txt
ftpsrv_log_file c:FDOSftpsrv.log
ftpsrv_filebuffer_size 16
ftpsrv_tcpbuffer_size 16
ftpsrv_packets_per_roll 2

mTCP configuration on FreeDOS 1.2 (mostly default settings)

packetint 0x60
mtu 1500
DOSRules
ftpsrv_password_file c:FDOSftppass.txt
ftpsrv_log_file c:FDOSftpsrv.log
# I forgot to uncomment these, but seems to have made no difference
#ftpsrv_filebuffer_size 16
#ftpsrv_tcpbuffer_size 16
#ftpsrv_packets_per_roll 2

I somehow doubt WinSCP is the culprit here, even though interacting with mTCP seems to be making it wonky. I use WinSCP nearly every day to connect to other systems, and I’ve never encountered this kind of behavior.

WinSCP configuration for both connections:

Protocol: FTP
Encryption: No encryption
Port number: 21
UTF-8 encoding for filenames: Auto
[ ] Trim VMS version numbers
[ ] Synchronize browsing
[x] Remember last used directory (turning this off didn’t help)

I’m inclined to believe the fault lies in an OS permission setting. I can however find no documentation about file permissions in FreeDos. The closest I can find is attributes, which gives me the following information (on FreeDOS 1.1):

[D----] FDOS
[----A] KERNAL.SYS
[----A] AUTOEXEC.BAT
[----A] COMMAND.COM
[----A] FDCONFIG.SYS
[----A] BOOTSECT.BIN
[D----] DUKE3D
[D----] RR2

which clearly have nothing to do with permissions.

Update 2017.04.03: As requested, here are my log files. (WinSCP wasn’t logging, so this is from this morning.)

Update: I tried with Core FTP, and here’s its log:

As you can see, it took just over 60 seconds to retrieve 54 bytes of directory information. Core FTP seems to be more successful, in that it eventually gets the directory listing. Some times it works quickly like you would expect FTP to, like when it transferred 1,279 bytes in 0.001 seconds, but it still seems to be hit and miss.

I thought maybe I just wasn’t letting WinSCP wait long enough, so I increased the timeout to two minutes. The only different behavior was that WinSCP hanged for two full minutes before displaying the error.

The mTCP log from these latest two attempts shows nothing more than «User signed in» and «Disconnect» with 0 timeouts and no errors, just like the full log further up this page.

I started thinking the router might be the issue, so I turned off and back on, but that made no difference. My computer is wired directly to the router by a 3-foot cord, and all other internet usage seems normal, so I’m not likely experiencing network interference.

Maybe its time I file a bug with the developer of mTCP and see what he comes up with.

Are you getting an error like “FTP cannot retrieve directory listing” when you try to access FTP server remotely?

This error is caused due to the bad settings in the FTP server, misconfiguration of FTP client, when passive mode setting disables and much more.

That’s why we often get requests from our customers to solve the error like “FTP cannot retrieve directory listing” as part of our Server Management Services.

Today, we’ll see how our Support Engineers fixed the issue for our customers.

What is “FTP cannot retrieve directory listing” error?

This error “FTP cannot retrieve directory listing” means that the user could not access the files from FTP server.

Users encounter an error message like this.

Error: Failed to retrieve directory listing

Now, let’s see the reasons for the error and the real solution to fix it.

Top 4 reasons and solutions to fix it

Here, we have the top 4 reasons for this error to occur and how we troubleshoot it.

1. Wrong encryption settings in FTP client

For instance, in FileZilla, when you connect to FTP server, you will see something like this.

Response: 227 Entering Passive Mode (11,22,33,44,167,111)
Command: MLSD
Error: Connection timed out
Error: Failed to retrieve directory listing

This happens when encryption is set to “Use explicit FTP over TLS if available” in FTP client settings.

So, we changed the encryption to “only use plain FTP” by executing the below steps.

1. First, we click on the File menu and choose Site Manager.

2. Then add Host and change Encryption to only use plain FTP.

3. Also, change the Logon Type to Normal and enter Username and Password.

4. Finally, click Connect to continue.

2. Problem with Passive mode

FTP operates in both active and passive mode. By default, FTP clients like FileZilla, CuteFTP uses passive as transfer mode.

But, in some cases, you may get an error like “FTP cannot retrieve directory listing” in passive mode. Then, try to change the default transfer mode by simply doing the steps below.

1. Go to Settings > Edit and click on Connection > FTP and choose Active.

2. Then under Active mode IP > select Ask your operating system for the external IP address.

3. Finally, under Passive mode > choose Fall back to active mode and click ok to save.

3. Missing passive port range in FTP server

In most of the cases “FTP cannot retrieve directory listing” error happens when passive port range is not mentioned FTP server configuration.

In cPanel for FTP servers like PureFTP, we perform the following steps.

1. We log in to the server via SSH.

2. Open the /var/cpanel/conf/pureftpd/local file and we add the entry like:

ForcePassiveIP: X.X.X.X

We add these changes to the file because FTP server exists behind the firewall.

3. Then we change the server’s default passive port range, by running the command.

echo "PassivePortRange: 49152 65534" >> /var/cpanel/conf/pureftpd/local
/usr/local/cpanel/scripts/setupftpserver pure-ftpd --force

4. Next, we configure the server to allow the passive port range to pass through the firewall.

5. Finally, restart the PureFTP service.

/usr/local/cpanel/scripts/setupftpserver pure-ftpd --force

4. Lacking Port range in firewall settings

Often this error happens when a firewall blocks passive FTP ports. So, it results in getting an error like “FTP cannot retrieve directory listing”.

We execute the following steps to add the passive port range to the firewall.

1. For firewall like iptables, we open the /etc/sysconfig/iptables file in a text editor.

2. Then add the entry like:

iptables -I INPUT -p tcp --dport 49152:65534 -j ACCEPT

3. Finally, run the command to save.

service iptables save

This is how we fix the error like “FTP cannot retrieve directory listing”.

[Having trouble in “FTP cannot retrieve directory listing” error? We’ll fix it for you.]

Conclusion

In short, “FTP cannot retrieve directory listing” error can happen due to a misconfiguration in firewall settings, incorrect passive port range, and more. Today, we’ve discussed the top 4 reasons for this error and how our Technical Engineers fixed them.

Error listing directory

Hi,

I have not had any problems with QNAP ftp for a quiet a long time and suddenly im unable to access ftp content over winscp or file zilla.
The message I get:

Timeout detected. (data connection)
Could not retrieve directory listing
Error listing directory ‘/xxxxx.com’.

Its stuck to one directory when showing error listing.
Port 21 is enabled and telnet connection is successful.
No changes to QNAP have been made prior this problem.
In QNAP manager i can see that user successfully logs in via winscp, and then connection drops because of time out and error listing directory.

What could be the problem of this?

Thanks in advance.

QTS Version, NAS model, what settings on FTP server are you using?, what ftp program are you using?

is this access from inside your LAN or the internet?

without you giving us information what do you want the community to do? guess?

Error listing directory ‘/xxxxx.com’.

this would suggest your ftp client is looking for a folder called ‘/xxxxx.com’

Thanks for pointing out about additional info in need to provide.

Model — TS-231 P
Firmware version — 4.5.4 1800
Attached ftp settings.

ftp1.png

ftp2.png

Applications Im using to access ftp are, WinSCP and FIleZilla
Attached settings using when connecting via WinScp

winscp.png

Im trying to connect from internet.
Port 21 is answering to telnet, but I don’t see anymore NAS message when connecting to port 21 via telnet, like it was before.
Now if im trying to connect to ftp it just shows Timeout detected, connection failed.

«this would suggest your ftp client is looking for a folder called ‘/xxxxx.com»

The folder was there, i double checked. But Im not sure why it was searching for that specific folder while connection to ftp(anyway now I don’t even get that error message)

Is there anything else that I need to provide?

Thanks in advance.

if your connecting from the internet I take it you have port 21 port forwarded (in your router) to your STATIC IP address of your NAS?

I see your Root folder is set to «/PBN FTP» so the folder called «/xxxxx.com» has to be inside the «/PBN FTP» folder else it would not find it.

personally I would not be opening up port 21 on the internet myself, I’d use a VPN, then ftp to the local ipaddress of the NAS, but each to there own.

im just providing support on this current NAS issue, im unaware of the router configuration, but I would say that it its port forwarded to NAS static ip.

Yes, all the necessary folders are stored in root «/PBN FTP» including «xxxxx.com», but im without clue why it try’s to access it straight away when connection to ftp root folder «Error listing directory ‘/xxxxx.com’.»

And now the bigger confusion is why 21 port is not working on NAS anymore. From router side its still accessible.

Under system status I see that there are some error packages, but don’t know what does that indicate

in WinSCP which I take it you are using do you have anything set for Remote Directory, which is in the advanced setting of Winscp entry for the NAS:

Screenshot 2021-11-05 154039.png

if the directory is there on the NAS then does the username you are logging in with, have the correct permissions to read and/or write to that xxxxx.com folder?

shame on me, there is xxxxx.com root directory specified, unchecked «Remember last used directory». :/

unfortunately I’m unable to test it yet as i have no clue why i cant connect to ftp anymore, ill have to wait till Monday when someone can access router when NAS is located.

I’m trying to use winSCP to FTP my server using FTPs and then synch with a backup folder. I have had this working fine from a PC on my work intranet (i.e. the same domain) however when I try to set it up off site (which is my whole point) the same script fails. The FTP log is as follows..

This fails whether I run from GUI or a previously tested and working scripted version. It looks from the log like theres a problem with a timeout on the directory listing, presumably it works locally as less lag

Any ideas if this is a winSCP setting (and if so where) or on the FTPserver side (Windows Web Server 2008 R2) ?
