1, sshfs usrname@172.23.65.122:/home/usrname ./122
在ubunutu 里面使用 sshfs 命令 映射网络上的文件系统时（samba）到本地时遇到read: Connection reset by peer 问题，
利用 sudo sshfs usrname@172.23.65.122:/home/usrname ./122 ,root权限去映射的话，虽然不会报错，但是映射后，只能用root权限去
访问，其他用户无法访问。
xxx@xxx-Lenovo:~$ sshfs usrname@172.23.65.122:/home/usrname
./122
read: Connection reset by peer
xxx@xxx-Lenovo:~$
解决办法：sudo sshfs -o allow_other yanhd@172.23.65.122:/home/yanhd ./122
添加 -o allow_other参数，允许其他用户访问即可。
2, ssh 使用问题。
ssh -v username@172.23.65.122 ，登录远程server 时，报下列错误WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
xxx@xxx-Lenovo:~/122$ ssh -v username@172.23.65.122

IT IS
POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be
eavesdropping on you right now (man-in-the-middle attack)!
It is also
possible that a host key has just been changed.
The fingerprint for the RSA
key sent by the remote host
is
91:65:a8:61:d3:54:eb:6b:b5:a8:07:df:d4:e7:77:27.
Please contact your
system administrator.
Add correct host key in /home/xxx/.ssh/known_hosts to
get rid of this message.
Offending RSA key in
/home/xxx/.ssh/known_hosts:1
remove with: ssh-keygen -f

RSA host key for 172.23.65.122
has changed and you have requested strict checking.
Host key verification
failed.
可能是由于远程server 的用户信息更新，之前已经在本地成功登录过，sever端用户信息更新，如密码变更后，再次登录可能会报此问题。
解决方法 ：sudo mv /home/xxx/.ssh/known_hosts /tmp
备注，以上“xxx” 为本机用户名
