机房电脑,通过远程端口映射,使得VPS:2222 映射到机房电脑:22:
ssh -N -f -R 2222:127.0.0.1:22 root@vpsIP
VPS则可以ssh到机房电脑:
ssh -p 2222 username@localhost
用ssh代理来浏览内网:
在校外电脑上,通过本地端口映射,使得校外电脑:2222 映射到VPS: 2222
ssh -N -f -L 2222:127.0.0.1:2222 root@vpsIP
现在可以登录机房电脑了:
ssh -p 2222 username@localhost
也可设置7070端口,使得浏览器通过代理访问资源:
ssh -qTfnN -D 7070 username@localhost -p 2222
chrome设置:
socks5,127.0.0.1,7070
添加一行到~/.ssh/config对应的host下,即可连接hpc:
ProxyCommand nc -X 5 -x 127.0.0.1:7070 %h %p
这样就可以愉快的登录校内大型机和下载图书馆文献啦~
