<pstyle="box-sizing:inherit;margin-top:0px;margin-bottom:16px;white-space-collapse:preserve;color:#606468;font-family:-apple-system,BlinkMacSystemFont,'SegoeUI','NotoSans',Helvetica,Arial,sans-serif,'AppleColorEmoji','SegoeUIEmoji';font-size:16px;background-color:#f7f7f8;">方法一:使用iptables命令打开终端,并以root权限登录。输入以下命令以禁止所有的出站连接:bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">iptables-AOUTPUT-jDROP这将在防火墙规则中添加一条规则,将所有的出站连接都丢弃掉。<pstyle="box-sizing:inherit;margin-top:0px;margin-bottom:16px;white-space-collapse:preserve;color:#606468;font-family:-apple-system,BlinkMacSystemFont,'SegoeUI','NotoSans',Helvetica,Arial,sans-serif,'AppleColorEmoji','SegoeUIEmoji';font-size:16px;background-color:#f7f7f8;">方法二:使用ufw命令(基于iptables的简化接口)打开终端,并以root权限登录。输入以下命令以禁用ufw:bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">ufwdisable这将禁用ufw防火墙,从而阻止所有的网络连接。<pstyle="box-sizing:inherit;margin-top:0px;margin-bottom:16px;white-space-collapse:preserve;color:#606468;font-family:-apple-system,BlinkMacSystemFont,'SegoeUI','NotoSans',Helvetica,Arial,sans-serif,'AppleColorEmoji','SegoeUIEmoji';font-size:16px;background-color:#f7f7f8;">无论您使用哪种方法,一旦禁止了Linux访问外网,您将无法访问互联网上的任何资源。如果您需要特定的访问权限或允许某些连接访问外网,可以根据需要进行相应的配置。<pstyle="box-sizing:inherit;margin-top:0px;margin-bottom:0px;white-space-collapse:preserve;color:#606468;font-family:-apple-system,BlinkMacSystemFont,'SegoeUI','NotoSans',Helvetica,Arial,sans-serif,'AppleColorEmoji','SegoeUIEmoji';font-size:16px;background-color:#f7f7f8;">请注意,禁止Linux访问外网可能会对系统的功能和服务造成影响,请谨慎操作。如果您还有其他问题,请随时咨询衡天云。
