I'm having an odd behavior with vsftp on all CentOS 4 servers... maybe 3 too, but I'm not on those much. I am transferring in port mode as I've never managed to get passive to work with a firewall running. Anyway, this is what happens. During normal transfers with few files.. it works perfectly. During the transfer of like a large website with hundreds of files in various

Seems the script kiddies are now hitting vsftp with dictionary attacks. I had three boxes showing around 12000 attempts from one IP yesterday. My thoughts are that there should be an upstream solution for this which is then supported by the upstream vendor. Yes, I know there are several 'other' solutions, but I'd really like to stay mainstream and use a supported method for

Hi - I have a ftp server running version 2.0.7 of vsftpd on a CentSO 5.2 server using iptables behind a Linksys router. The setup works for UNIX machines on either side of the Linksys router. For the Windows machines it only works if they're behind the Linksys router - ftp does NOT work if they're outside the Linksys router. I'd like to solve two problems: (1) make ftp work

I have a vsftp server hosted on custom dyndns site. We have a 4mb ADSL connection. When I tried to download the files from the ftp server with wan IP address or the dyndns address it downloads some files and disconnects. Please find below an extract from the log file (ace ftp client). I would appreciate if someone could guide me, possibly with a solution for this problem. Many thanks

Hi, I want to setup vsftp on centos 4.5. 2 types of ftp. they are active and pasive. What is the default type ftp type o CentOS ? Is is PASIVE ftp? in /etc/vsftpd/vsftpd.conf, I found below line. What should I do for below line? # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES Should I COMMENT it out? I need a very secure ftp service. YOUR

Centos 6, stock installation, no additional repos added. vsftp works fine in regular mode, going to ssl I got issues. I get as far as 'directory listing' and it dies. It times out and disconnects. file: /etc/sysconfig/iptables-config added: IPTABLES_MODULES="ip_conntrack_ftp" (without this line, ftp normally fails, afraid it may be causing issues with the ssl) iptables -A

Hi, I use for a customer a Linux router/firewall with 1 internal interface connected to the LAN and 3 external interfaces connected to 3 different ISP. I use a kernel 2.6.17 with a routes patch from Julian Anastasov. I mark outgoing FTP traffic for the routing. With the rules below I do not have a problem with the active/normal FTP to connect on FTP server. But the passive FTP does not pass

I'm having a heck of a time getting vsftpd to work properly. When Iptables are OFF, it works fine, and when iptables is on, it dies. When I try ftp from a command line, here's what the session looks looks like: [root at mylaptop ~]# ftp ftp.server.com Connected to ftp.server.com. 220 Welcome to My Company FTP 530 Please login with USER and PASS. 530 Please login with USER and PASS.

Hi, I'm currently setting up a local FTP server, to receive disk images sent with G4L (Ghost4Linux). This server has been running Slackware Linux before, and the Vsftpd setup was relatively simple. With CentOS things seem to be slightly different, so I'm currently trying to work things out. For the moment, two things seem to be creating problems, the simple iptables firewall and

Hi all, With SELinux in permissive mode and iptables running, I'm unable to retrieve directory listings with ftp. stop iptables, and all appears again. This seems to be unrelated to passive/port modes for ftp client. If this is off topic, please let me know offlist and I'll take my question elsewhere. Otherwise I'll repost with output of # iptables status TIA, ~Ray

I just installed CentOS4 on my main server. It runs proftpd and is not NATted.. When I did the install I said to allow FTP and HTTP. I can ftp from windows dos ftp client. In IE I get "Unable to build data connection: No route to host" ncftp I get.. Data connection timed out. Falling back to PORT instead of PASV mode. List failed. Wget and FireFox just time out. Anything I need

Hi, I''m using the same set of firewall rules of 2.0.x (sorry, I can''t remember the exact minor version) and put it to work with 2.0.9. And now I can''t do passive ftp (was working before). I see that my NEWNOTSYN is set to Yes, and the loc->net rule is blocking 1024:65535. But I believe with the ip_conntrack_ftp, the passive mode would be allowed, since

I have Centos 5.7 64bit; I have installed vsftpd as standalone service and using it for two years now with no problem. Suddenly; only it works with active mode. The passive mode stops working and gives time out. Firewall is disabled and SELinux is set to permissive. I ran tcpdump and I noticed that only first three packets reached the FTP for passive mode and no more packets on other ports #

I was not sure why vsftp (or any other ftp software) was installed as part of the webserver. some quick notes, hope it helps anyone else having an issue. So I yum installed it. I had a bear of a time. But I finally got it to work doing the following. I had to add ip_conntrack_ftp to my iptables-config file or it would not work IPTABLES_MODULES="ip_conntrack_ftp" I had to add this

I am moving from a server from running Red Hat 7.2 (with ProFTP) to Centos 3 (with vsFTP). There is a setting in ProFTP that lets me set the default ftp login directory for a specific user and I would like to do the same with vsFTP. The reason being is I have a 'webadmin' user that I use for uploading web content. I am thinking I could make the home directory of the webadmin /var/www in

Will the following rules work to mark and shape OUTBOUND ftp speed (passive ftp ports 50000-60000) on my linux server?
