Bloccare internet alle applicazioni?
sto usando ubuntu 7.04 da un po', e ora che ci penso, come si puo' fare sotto linux a bloccare l'accesso ad internet a determinate applicazioni?
anche app win32 che girano sotto wine... su windows e' facilissimo, basta usare un personal firewall e via, ma su linux non ne ho davvero la piu' pallida idea

si ho visto firestarter, ma a me serve un modo per bloccare la tale applicazione, non interi domini/indirizzi

Puoi sempre emulare un firewall windows
![]() Comunque se è un applicazione di quelle standard blocchi solo la porta in base all' ip ed il gioco è fatto senza problemi. Se poi non è così devi usare qualche regola un po' più specifica che sarà qualcosa tipo (molto tipo diciamo): Codice:
iptables -A OUTPUT -m owner --cmd-owner <NOME_PROGRAMMA> -j DROP (e blocchi la connessione ad un programma) iptables -A OUTPUT -m owner --uid-owner <UTENTE> -j DROP (e dovresti segare giù tutta la roba di quell' utente) |

da man:
Codice:
owner This module attempts to match various characteristics of the packet creator, for locally-generated packets. It is only valid in the OUTPUT chain, and even this some packets (such as ICMP ping responses) may have no owner, and hence never match. --uid-owner userid Matches if the packet was created by a process with the given effective user id. --gid-owner groupid Matches if the packet was created by a process with the given effective group id. --pid-owner processid Matches if the packet was created by a process with the given process id. (Please note: This option requires kernel support that might not be available in official Linux kernel sources or Debian’s pack‐ aged Linux kernel sources. And if support for this option is available for the specific Linux kernel source version, that support might not be enabled in the current Linux kernel binary.) --sid-owner sessionid Matches if the packet was created by a process in the given ses‐ sion group. (Please note: This option requires kernel support that might not be available in official Linux kernel sources or Debian’s pack‐ aged Linux kernel sources. And if support for this option is available for the specific Linux kernel source version, that support might not be enabled in the current Linux kernel binary.) --cmd-owner name Matches if the packet was created by a process with the given command name. (Please note: This option requires kernel support that might not be available in official Linux kernel sources or Debian’s pack‐ aged Linux kernel sources. And if support for this option is available for the specific Linux kernel source version, that support might not be enabled in the current Linux kernel binary.) NOTE: pid, sid and command matching are broken on SMP Non conosco programmi che implementano questa cosa, me lo son scritto come test tempo fa ma è restato molto in test (al solito, una volta che vedo come funziona una cosa la pianto lì ![]()
