Sto accedendo a Internet utilizzando il proxy del mio ISP che blocca molti servizi come netcat. Così ho installato proxychain e ora posso usare netcat.
Non ho aggiunto alcun IP proxy esterno al file di configurazione di proxychains. Ho appena aggiunto il mio proxy ISP su di esso. Posso vedere i pacchetti inviati direttamente al mio proxy ISP.
Quindi come funziona?
proxychains.conf:
# proxychains.conf VER 3.1
#
# HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS.
#
# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
#dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see chain_len) from the list.
# this option is good to test your IDS :)
# Make sense only if random_chain
#chain_len = 2
# Quiet mode (no output from library)
#quiet_mode
# Proxy DNS requests - no leak for DNS data
proxy_dns
# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000
# ProxyList format
# type host port [user pass]
# (values separated by 'tab' or 'blank')
