在Debian上設置FTP服務器的帶寬限制,通常需要使用vsftpd
(Very Secure FTP Daemon)服務器軟件,并結合trickle
或wondershaper
等工具來實現帶寬限制。以下是具體步驟:
trickle
安裝trickle
:
sudo apt update
sudo apt install trickle
配置vsftpd
:
編輯/etc/vsftpd.conf
文件,確保以下配置項存在并正確設置:
local_enable=YES
write_enable=YES
chroot_local_user=YES
allow_writeable_chroot=YES
創建啟動腳本:
創建一個啟動腳本,用于在啟動vsftpd
時使用trickle
限制帶寬。例如,創建文件/etc/init.d/vsftpd-trickle
:
#!/bin/sh
### BEGIN INIT INFO
# Provides: vsftpd-trickle
# Required-Start: $local_fs $network
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: Start vsftpd with trickle bandwidth limiting
### END INIT INFO
PATH=/sbin:/bin:/usr/sbin:/usr/bin
DESC="vsftpd with trickle bandwidth limiting"
NAME=vsftpd-trickle
DAEMON=/usr/sbin/vsftpd
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
test -x $DAEMON || exit 0
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \
--listen_port=21 --user=ftp --group=ftp --chroot_local_user=YES --allow_writeable_chroot=YES
trickle -d 100 -u 100 $DAEMON &
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
killall $DAEMON
killall trickle
echo "$NAME."
;;
restart|force-reload)
$0 stop
$0 start
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
exit 1
;;
esac
exit 0
賦予腳本執行權限:
sudo chmod +x /etc/init.d/vsftpd-trickle
啟動服務:
sudo service vsftpd-trickle start
wondershaper
安裝wondershaper
:
sudo apt update
sudo apt install wondershaper
配置vsftpd
:
編輯/etc/vsftpd.conf
文件,確保以下配置項存在并正確設置:
local_enable=YES
write_enable=YES
chroot_local_user=YES
allow_writeable_chroot=YES
創建啟動腳本:
創建一個啟動腳本,用于在啟動vsftpd
時使用wondershaper
限制帶寬。例如,創建文件/etc/init.d/vsftpd-wondershaper
:
#!/bin/sh
### BEGIN INIT INFO
# Provides: vsftpd-wondershaper
# Required-Start: $local_fs $network
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: Start vsftpd with wondershaper bandwidth limiting
### END INIT INFO
PATH=/sbin:/bin:/usr/sbin:/usr/bin
DESC="vsftpd with wondershaper bandwidth limiting"
NAME=vsftpd-wondershaper
DAEMON=/usr/sbin/vsftpd
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
test -x $DAEMON || exit 0
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \
--listen_port=21 --user=ftp --group=ftp --chroot_local_user=YES --allow_writeable_chroot=YES
wondershaper eth0 100 100 &
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
killall $DAEMON
killall wondershaper
echo "$NAME."
;;
restart|force-reload)
$0 stop
$0 start
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
exit 1
;;
esac
exit 0
賦予腳本執行權限:
sudo chmod +x /etc/init.d/vsftpd-wondershaper
啟動服務:
sudo service vsftpd-wondershaper start
ProFTPD
,并結合SSL/TLS加密傳輸。通過以上步驟,您可以在Debian上成功設置FTP服務器的帶寬限制。
