VirtualBox or Genymotion Emulator blocks program protocols through host's port proxy -

-

something blocks program protocols (for example, ftp) when connect through port proxy server (server_ip:port) started on genymotion android emulator. telnet connects server_ip:port successfully, browser or other programs, can't. direct connection, not through port proxy, works perfectly.

i switched off firewalls , antiviruses ann anythig can block network data.

scenario:

1) on emulator - start ftp server of es explorer (or other listening server)

2) on host's browser locate - ftp_:_//_emulator_ip_:_emulator_port

3) , operate emulator files on ftp.

then make:

4) on host command line - netsh interface portproxy add v4tov4 emulator_port emulator_ip emulator_port

5) on host - telnet host_ip emulator_port or telnet 127.0.0.1 emulator_port

6) , telnet connected

7) on host's browser or other ftp-programms - ftp_:_//_host_ip_:_emulator_port_ or ftp_:_//127.0.0.1:_emulator_port or ftp_:_//_host_name_:_emulator_port

8) , cannot access ftp service @ all

i hade

who guilty? virtualbox or genymotion emulator? blocking programm protocols (such ftp) on port proxy?

what should access genymotion emulator via port proxy?

thank you!

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
