  • Axel --max-speed=x, -s x You can specify a speed (bytes per second) here and Axel will try to keep the average speed around this speed. Useful if you don?t want the program to suck up all of your bandwidth.

  • Say I have configured a fully optimized squid server A listen on [xxxx:xxxx::xxxx]:3128, within ISP_foo. But when I was with ISP_bar , I can not access the proxy with full speed due to ISP's limit upon the normal clients among different ISP. If you are curious where the ridiculous ISPs are, I'll tell you the truth --that's CHINA. However, servers' network connection is not enslaved to that limitation, especially with IPv6. So, I can do this socat linefu on a server B of ISP_bar. me >> B(ISP_bar)>> A(ISP_foo)

    socat TCP4-LISTEN:3128,reuseaddr,fork TCP6:[xxxx:xxxx::xxxx]:3128
