These two scripts are designed to correct this issue and get vsftpd's passive connections work in dynamic IP environment behind the NAT.
Place this script in the file named vsftpd.ip in /usr/sbin/ ============================================ #!/bin/sh # Script is dedicated for setting real (external) IP-address in pasv_address= # parameter in vsftpd.conf. # It's neccessary for running vsftp in dynamic DNS environment # behind NAT in passive mode. It checks external IP every 5 minutes, then sleeps. # Wriiten by: ais77 (http://forum.ubuntu.ru) # Configure these settings: CONFIG_FILE=/etc/vsftpd.conf # Location of vsftpd.conf CONFIG_FILE_TMP=/etc/vsftpd.conf.tmp # Location of temporary file DOMAIN=ais77.homeftp.net # Your external domain (i.e. from DynDNS.com) touch $CONFIG_FILE_TMP realIP=`dig $DOMAIN +short` vsftpdIP=`sed -n "/pasv_address=/s/pasv_address=//p" $CONFIG_FILE` while : do if [ $realIP != $vsftpdIP ]; then sed "s/$vsftpdIP/$realIP/" $CONFIG_FILE > $CONFIG_FILE_TMP mv -f $CONFIG_FILE_TMP $CONFIG_FILE /etc/init.d/vsftpd restart fi sleep 5m done exit 0 ============================================ Make shure to set your data for DOMAIN= and get this file executable: ~$ sudo chmod +x /usr/sbin/vsftpd.ip Second one will be a daemon run wrapper (if you want to your vsftpd.ip run as daemon at startup) Place this one in file named ipftp in etc/init.d/ ============================================ #!/bin/sh # /etc/init.d/ipft # vsftpd.ip daemon script # Written by ais77 <http://forum.ubuntu.ru> set -e DAEMON=/usr/sbin/vsftpd.ip NAME=ipftp PIDFILE=/var/run/vsftpd/vsftpd.ip.pid # Exit if vsftpd.ip is already running test -x $DAEMON || exit 0 . /lib/lsb/init-functions case "$1" in start) log_begin_msg "Starting vsftpd.ip daemon: $NAME" [ -d /var/run/vsftpd ] || mkdir -p /var/run/vsftpd start-stop-daemon --start --background -m --pidfile $PIDFILE --exec $DAEMON && log_end_msg 0 || log_end_msg 1 ;; stop) log_begin_msg "Stopping vsftpd.ip daemon: $NAME" start-stop-daemon --stop --pidfile $PIDFILE --oknodo && log_end_msg 0 || log_end_msg 1 rm -f $PIDFILE ;; restart) $0 stop $0 start ;; *) log_success_msg "Usage: /etc/init.d/$NAME {start|stop|restart}" exit 1 ;; esac exit 0 ============================================ Also make shure to set this file executable: ~$ sudo chmod +x /etc/init.d/ipftp To start daemon execute: ~$ sudo /etc/init.d/ipftp start To set vsftpd.ip daemon run at startup automatically: ~$ sudo update-rc.d ipftp defauts Enjoy. -- Wrong pasv_address behind the NAT in dynamic IP environment https://bugs.launchpad.net/bugs/292384 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
