To fix this, make sure the server does not listen on IPv6 address (what is the default behavior, which you are overriding by setting listen_ipv6=YES): listen_ipv6=NO *resp* '227 Entering Passive Mode (0,0,0,0,50,245).'ĬonnectionRefusedError: Connection refusedįrom the code it looks like, it will always send the 0,0,0,0, if the public pasv_address is set, but the server has a (local) IPv6 address. Test through Python ftplib from ftplib import FTP ![]() However, with it works with EPSV (with IPV6 checkbox selected), the log as below: 220 (vsFTPd 3.0.3)Ģ29 Entering Extended Passive Mode (|||13082|)Ĥ. With PASV mode, I cannot connect to FTP server, the log is: 220 (vsFTPd 3.0.3) I searched around but find no answers, any body can help me with this? However, it works with EPSV, don't know why. When I view my server logs I don't see much other than this every once in a while. My ec2 security group has port 50000 - 50100 open When I view the local port range on the server, /proc/sys/net/ipv4/ip_local_port_range the following are open. #Symbolic host names are also accepted for gateways with dynamic IPįorcePassiveIP `` "my cname record is mapped to my ec2 public dns" PASV IP #Force an IP address in PASV/EPSV/SPSV replies. Port Range #Port range for passive connections replies. I have the following pureftp configuration The odd part is some people are unable to log in while others are. Status: Directory listing of "/" successful Status: Server sent passive reply with unroutable address. I'm receiving the following error in FileZilla Status: Connected I'm trying to get it to run in passive mode which I thought was working, however I'm finding it may not be working correctly. I have pureftp running on an AWS ec2 instance.
