Now I didn't know OS can or does limit connection for FTP clients, though I suspected as much after I started getting this error. It's very likely it's an understatement :) Nevertheless, I must use them and I cannot change their configuration :( And since it's possible in Windows, I hope there's a way to make it work with Linux clients too. Yes, based on my previous experience with these servers and their admins, it's very likely they aren't brilliantly configured. I'm going to suggest that the FTP Server in question isn't actually all that brilliantly configuredĪctually there are 2 of them I use frequently, and I get this error with both of them. Are you using FileZilla from Ubuntu Software Centre in Ubuntu 10.04 LTS? I don't think I even looked at those settings when I first grabbed FileZilla. I went and had a poke through my copy of FileZilla and found that the current settings are tamely 'Maximum simultaneous transfers: (1-10). Sorry I am not telling you anything very clever that will fix it for you: Set up a Windows VM and run filezilla in there if you can't correct that FTP server. Please tell me what version of Windows it is you have there - if it's not a server edition and it precedes Windows 7 then it's very likely got the '10 internet sockets' hard limit - I can't speak for Windows 7 but I bet MS still thinks the average home user (including professional) should never need more than 10 sockets and it's probably an internet attack if they ask for them! I'm going to suggest that the FTP Server in question isn't actually all that brilliantly configured and just because you are probably using an edition of Windows that has a hard limit of 10 simultaneous internet connections doesn't make it Linux's fault for granting the 'calling program' as many internet sockets as it asks for, at least to a much a greater limit than the people at MS thought certain editions of their stuff should have. I've had to deselect stuff named with terminology like "Limit connections from individual clients" in both an MS FTP setup and ProFTPD, although it might be an FTP server awfully like ProFTP that I used in CentOS upon a time that I can't find a reference to right now! I configured 3 of the four FTP servers myself and the fourth is configured by someone that I know 'knows about as good as I do'. I use filezilla in both Linux and Windows and I don't get your error, ever. I contact several different FTP servers every week and I sometimes transfer hundreds of files to or from them. and this happens with many different FTP servers. Connection is refused for separate particular files, if I click "Ignore" each time the rest of files are transfered perfectly well, so I assume it's the very same error.Īnything I could do? This really drives me mad, transfering large numbers of files is a part of my everyday job. When I try to use native ftp client (not sure how is it called, the one in Places -> Connect to a server) I get abstract "connection refused" error every time I transfer large number of files. I did try to switch between passive and active modes (not sure if it's related at all, just last desperate attempt), and it didnt change anything either. I did try to limit maximum allowed connections for Filezilla, both in server settings and in global settings, it didnt change anything. At first I thought it's a filezilla bug, however I get the same error basically with every FTP client I've tried, including Total Commander under Wine. Now you should be able to login as root with your SSH keys.I keep getting the "sorry, the maximum allowed clients from your host (10) are already connected" error whenever I try to transfer a large number of files. If the SFTP Protocol is specified, it is possible to specify the Logon Type as "Key File" and specify the location of the private key file ( my-ssh-key). This is done (I believe) in the profile settings in the Site Manager of the FileZilla client. Copy the contents of my-ssh-key.pub into this file: /root/.ssh/authorized_keys (using sudo access).Ĭonfigure FileZilla to use Key logon. Login to Ubuntu with your account with sudo access. Generate an SSH keypair, if you don't have one (can be done with this command: ssh-keygen -t rsa -b 2048 -f my-ssh-key - this will generate 2 files: my-ssh-key and my-ssh-key.pub). In order for you to log in as root with FileZilla (or any other SFTP tool), you need to setup SSH key authentication. Root access with password is disabled by default on Ubuntu. Disclaimer: I'm not an expert on FileZilla, so for specific instructions please refer to FileZilla documentation.
