澳洲的DSS

新到澳洲的同学可以关注一下这个Department of Social Services,里面提供了一些免费的服务。比如文档翻译。我记得去年查的时候我的visa还可以翻译的,今年竟然不行了!

https://translating.dss.gov.au/en/about-this-service/

The Free Translating Service can be used by anyone who holds one of the following visa subclasses:

100, 101, 102, 103, 105, 106, 114, 115, 116, 117, 118, 119, 120, 121, 124, 126, 132, 134, 135, 136, 137, 138, 139, 143, 151, 175, 176, 186, 187, 189, 190, 200, 201, 202, 203, 204, 300, 309, 445, 449, 785, 786, 790, 800, 801, 802, 804, 808, 820, 834, 835, 836, 837, 838, 846, 851, 852, 855, 856, 857, 858, 859, 861, 862, 863, 864, 866, 880, 881, 882, 883, 885, 886, 887, 888, 890, 891, 892, 893

TIS National does not provide a commercial document translation service.

If you need to complete a commercial translation, you can search for a qualified translator through the National Accreditation Authority for Translating and Interpreting (NAATI) website.

使用反向ssh从外网访问内网主机

通过本方法可以从外网通过ssh访问内网的主机,前提是内网的主机要能够访问Internet,还需要一台具有公网地址的主机。

在内网主机上执行以下命令,其中:120.24.3.x是一台公网主机,该主机可以是云主机或者通过路由器端口映射到内网的一台主机,1111是这台公网主机映射的端口。

ssh -NfR 1111:localhost:22 root@120.24.3.x -p 22

执行完毕,会有一个后台进程运行

[root@localhost ~]# ps -ef |grep ssh
root 1115 1 0 10:59 ? 00:00:00 /usr/sbin/sshd
root 1258 1115 0 11:00 ? 00:00:01 sshd: root@pts/0 
root 3604 1 0 11:50 ? 00:00:00 ssh -NfR 1111:localhost:22 root@120.24.3.x -p 22
root 3606 1115 0 11:50 ? 00:00:00 sshd: root@pts/1 
root 3647 3610 0 11:57 pts/1 00:00:00 grep ssh

然后在公网主机上ssh本地的端口1111就可以访问内网的主机了

ssh root@localhost -p 1111
