ssh命令
适用命令及方案如下：
【远程连接及执行命令】
ssh -p22 [email protected].0.0.19
ssh -p22 [email protected].0.0.19 /sbin/ifconfig
【远程拷贝：推送及拉取】
scp -P22 -r -p /etc [email protected].0.0.19:/tmp/
scp -P22 -r -p [email protected].0.0.19:/tmp/ /etc
【安全的FTP功能】
sftp -oPort=22 [email protected].0.0.19
利用ssh-v的调试功能查找慢的原因
windows上传下载需要在CRT文件下找到sftp就可以重本地上传东西了
put 上传
get 下载
检查openssh和openssl是否安装

rpm -qa opensshopenssl 1>>~/ssh.ok 2>>ssh.bug
限制外网IP
优化：
以下各项开机时已经实现优化：
Port52113
PermitRootLogin no
PermitEmptyPasswords no
UseDNS no
GSSAPIAuthentication no
只允许内网IP172.16.1.61登录
echo ‘###限制登录内网IP###‘1>>~/ssh.ok 2>>ssh.bug
cp /etc/ssh/sshd_config{,.ssh.ori}
ls /etc/ssh/sshd_config.ssh.ori 1>>~/ssh.ok 2>>ssh.bug
sed -i ‘13a ListenAddress 172.16.1.61:52311‘/etc/ssh/sshd_config
sed -n ‘13,18p‘/etc/ssh/sshd_config 1>>~/ssh.ok 2>>ssh.bug
ssh实现批量管理
一键生成密钥：
法一：
ssh-keygen -t dsa -P ‘‘ -f ~/.ssh/id_dsa >/dev/null 2>&1
法二：
echo -e "\n"|ssh-keygen -t dsa -N "" >/dev/null 2>&1
echo ‘###查看生成密钥情况###‘1>>~/ssh.ok 2>>ssh.bug
ls -l ~/.ssh 1>>~/ssh.ok 2>>ssh.bug
分发密钥
echo ‘###查看生成密钥情况###‘1>>~/ssh.ok 2>>ssh.bug
ssh-copy-id -i ~/.ssh/id_dsa.pub [email protected] （默认22端口使用）
ssh-copy-id -i ~/.ssh/id_dsa.pub "-p [email protected]" （改端口使用）
批量分发密钥
批量分发文件
