1.Xftp連接配接出錯

2.解決方案

# 1.編輯檔案
vim /etc/ssh/sshd_config
# 2.修改以下内容
Subsystem sftp /usr/libexec/openssh/sftp-server
# 3.重新加載
/etc/init.d/sshd reload
# 4.重新開機即可
/etc/init.d/sshd restart      

出現下圖表示成功

3.遇到的問題

​

​找不到sshd檔案​

​

-bash: /etc/init.d/sshd: No such file or directory      

在​

​/etc/init.d/​

​​下建立一個sshd檔案

輸入以下内容：

#!/bin/sh
# Start/stop/restart the secure shell server:

sshd_start() {
  # Create host keys if needed.
  if [ ! -r /etc/ssh/ssh_host_key ]; then
    /usr/bin/ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_key -N '' 
  fi
  if [ ! -f /etc/ssh/ssh_host_dsa_key ]; then
    /usr/bin/ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N ''
  fi
  if [ ! -f /etc/ssh/ssh_host_rsa_key ]; then
    /usr/bin/ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N ''
  fi
  /usr/sbin/sshd
}

sshd_stop() {
  killall sshd
}

sshd_restart() {
  if [ -r /var/run/sshd.pid ]; then
    echo "WARNING: killing listener process only.  To kill every sshd process, you must"
    echo "         use 'rc.sshd stop'.  'rc.sshd restart' kills only the parent sshd to"
    echo "         allow an admin logged in through sshd to use 'rc.sshd restart' without"
    echo "         being cut off.  If sshd has been upgraded, new connections will now"
    echo "         use the new version, which should be a safe enough approach."
    kill `cat /var/run/sshd.pid`
  else
    killall sshd
  fi
  sleep 1
  sshd_start
}

case "$1" in
'start')
  sshd_start
  ;;
'stop')
  sshd_stop
  ;;
'restart')
  sshd_restart
  ;;
*)
  echo "usage $0 start|stop|restart"
esac      

然後修改權限：

# 沒有修改權限通路會報錯
-bash: /etc/init.d/sshd: Permission denied

# 修改通路權限
chmod 755 sshd
