sancho cannot run Mldonkey

[i2000s]

as the title shows, I cannot run Sancho to load Mlnet or Mldonkey.
It always shows me to configure the host settings. 127.0.0.1:4000 and the like do not work for me!
How can I do next?

Sorry for missing my Chinese input method...

[到处看看]

在终端里运行mlnet，再打开Sancho。
