Linux comes with a host based firewall called Netfilter. According to the official project site: This Linux based firewall is controlled by the program called iptables to handles filtering for IPv4, and ip6tables handles filtering for IPv6. I strongly recommend that you first read our quick tutorial that explains how to configure a host-based firewall called Netfilter (iptables) under CentOS / RHEL / Fedora / Redhat Enterprise Linux. This post list most common iptables solutions required by a new Linux user to secure his or her Linux operating system from intruders. IPTABLES Rules Example Most of the actions listed in this post are written with the assumption that they will be executed by the root user running the bash or any other modern shell. Do not type commands on remote system as it will disconnect your access. For demonstration purpose I've used RHEL 6.x, but the following command should work with any modern Linux distro. This is NOT a tutorial on how to set iptables. See tutorial here. It is a quick cheat sheet to common iptables commands. #1: Displaying the Status of Your Firewall Type the following command as root: # iptables -L -n -v Sample outputs: Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Above output indicates that the firewall is not active. The following sample shows an active firewall: # iptables -L -n -v Sample outputs: Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 DROP all -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID 394 43586 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 93 17292 ACCEPT all -- br0 * 0.0.0.0/0 0.0.0.0/0 1 142 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT all -- br0 br0 0.0.0.0/0 0.0.0.0/0 0 0 DROP all -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID 0 0 TCPMSS tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp flags:0x06/0x02 TCPMSS clamp to PMTU 0 0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 0 0 wanin all -- vlan2 * 0.0.0.0/0 0.0.0.0/0 0 0 wanout all -- * vlan2 0.0.0.0/0 0.0.0.0/0 0 0 ACCEPT all -- br0 * 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT 425 packets, 113K bytes) pkts bytes target prot opt in out source destination Chain wanin (1 references) pkts bytes target prot opt in out source destination Chain wanout (1 references) pkts bytes target prot opt in out source destination Where, -L : List rules. -v : Display detailed information. This option makes the list command show the interface name, the rule options, and the TOS masks. The packet and byte counters are also listed, with the suffix 'K', 'M' or 'G' for 1000, 1,000,000 and 1,000,000,000 multipliers respectively. -n : Display IP address and port in numeric format. Do not use DNS to resolve names. This will speed up listing. #1.1: To inspect firewall with line numbers, enter: # iptables -n -L -v --line-numbers Sample outputs: Chain INPUT (policy DROP) num target prot opt source destination 1 DROP all -- 0.0.0.0/0 0.0.0.0/0 state INVALID 2 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 4 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy DROP) num target prot opt source destination 1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 2 DROP all -- 0.0.0.0/0 0.0.0.0/0 state INVALID 3 TCPMSS tcp -- 0.0.0.0/0 0.0.0.0/0 tcp flags:0x06/0x02 TCPMSS clamp to PMTU 4 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 5 wanin all -- 0.0.0.0/0 0.0.0.0/0 6 wanout all -- 0.0.0.0/0 0.0.0.0/0 7 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 Chain OUTPUT (policy ACCEPT) num target prot opt source destination Chain wanin (1 references) num target prot opt source destination Chain wanout (1 references) num target prot opt source destination You can use line numbers to delete or insert new rules into the firewall. #1.2: To display INPUT or OUTPUT chain rules, enter: # iptables -L INPUT -n -v # iptables -L OUTPUT -n -v --line-numbers #2: Stop / Start / Restart the Firewall If you are using CentOS / RHEL / Fedora Linux, enter: # service iptables stop # service iptables start # service iptables restart You can use the iptables command itself to stop the firewall and delete all rules: # iptables -F # iptables -X # iptables -t nat -F # iptables -t nat -X # iptables -t mangle -F # iptables -t mangle -X # iptables -P INPUT ACCEPT # iptables -P OUTPUT ACCEPT # iptables -P FORWARD ACCEPT Where, -F : Deleting (flushing) all the rules. -X : Delete chain. -t table_name : Select table (called nat or mangle) and delete/flush rules. -P : Set the default policy (such as DROP, REJECT, or ACCEPT). #3: Delete Firewall Rules To display line number along with other information for existing rules, enter: # iptables -L INPUT -n --line-numbers # iptables -L OUTPUT -n --line-numbers # iptables -L OUTPUT -n --line-numbers | less # iptables -L OUTPUT -n --line-numbers | grep 202.54.1.1 You will get the list of IP. Look at the number on the left, then use number to delete it. For example delete line number 4, enter: # iptables -D INPUT 4 OR find source IP 202.54.1.1 and delete from rule: # iptables -D INPUT -s 202.54.1.1 -j DROP Where, -D : Delete one or more rules from the selected chain #4: Insert Firewall Rules To insert one or more rules in the selected chain as the given rule number use the following syntax. First find out line numbers, enter: # iptables -L INPUT -n --line-numbers Sample outputs: Chain INPUT (policy DROP) num target prot opt source destination 1 DROP all -- 202.54.1.1 0.0.0.0/0 2 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state NEW,ESTABLISHED To insert rule between 1 and 2, enter: # iptables -I INPUT 2 -s 202.54.1.2 -j DROP To view updated rules, enter: # iptables -L INPUT -n --line-numbers Sample outputs: Chain INPUT (policy DROP) num target prot opt source destination 1 DROP all -- 202.54.1.1 0.0.0.0/0 2 DROP all -- 202.54.1.2 0.0.0.0/0 3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state NEW,ESTABLISHED #5: Save Firewall Rules To save firewall rules under CentOS / RHEL / Fedora Linux, enter: # service iptables save In this example, drop an IP and save firewall rules: # iptables -A INPUT -s 202.5.4.1 -j DROP # service iptables save For all other distros use the iptables-save command: # iptables-save > /root/my.active.firewall.rules # cat /root/my.active.firewall.rules #6: Restore Firewall Rules To restore firewall rules form a file called /root/my.active.firewall.rules, enter: # iptables-restore < /root/my.active.firewall.rules To restore firewall rules under CentOS / RHEL / Fedora Linux, enter: # service iptables restart #7: Set the Default Firewall Policies To drop all traffic: # iptables -P INPUT DROP # iptables -P OUTPUT DROP # iptables -P FORWARD DROP # iptables -L -v -n #### you will not able to connect anywhere as all traffic is dropped ### # ping cyberciti.biz # wget http://www.kernel.org/pub/linux/kernel/v3.0/testing/linux-3.2-rc5.tar.bz2 #7.1: Only Block Incoming Traffic To drop all incoming / forwarded packets, but allow outgoing traffic, enter: # iptables -P INPUT DROP # iptables -P FORWARD DROP # iptables -P OUTPUT ACCEPT # iptables -A INPUT -m state --state NEW,ESTABLISHED -j ACCEPT # iptables -L -v -n ### *** now ping and wget should work *** ### # ping cyberciti.biz # wget http://www.kernel.org/pub/linux/kernel/v3.0/testing/linux-3.2-rc5.tar.bz2 #8: Drop Private Network Address On Public Interface IP spoofing is nothing but to stop the following IPv4 address ranges for private networks on your public interfaces.

For IPv4, this must be a number between (including) 0 and 32. #21: HowTO: Use iptables Like a Pro For more information about iptables, please see the manual page by typing man iptables from the command line: $ man iptables You can see the help using the following syntax too: # iptables -h To see help with specific commands and targets, enter: # iptables -j DROP -h #21.1: Testing Your Firewall Find out if ports are open or not, enter: # netstat -tulpn Find out if tcp port 80 open or not, enter: # netstat -tulpn | grep :80 If port 80 is not open, start the Apache, enter: # service httpd start Make sure iptables allowing access to the port 80: # iptables -L INPUT -v -n | grep 80 Otherwise open port 80 using the iptables for all users: # iptables -A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT # service iptables save Use the telnet command to see if firewall allows to connect to port 80: $ telnet www.cyberciti.biz 80 Sample outputs: Trying 75.126.153.206... Connected to www.cyberciti.biz. Escape character is '^]'. ^] telnet> quit Connection closed. You can use nmap to probe your own server using the following syntax: $ nmap -sS -p 80 www.cyberciti.biz Sample outputs: Starting Nmap 5.00 ( http://nmap.org ) at 2011-12-13 13:19 IST Interesting ports on www.cyberciti.biz (75.126.153.206): PORT STATE SERVICE 80/tcp open http Nmap done: 1 IP address (1 host up) scanned in 1.00 seconds I also recommend you install and use sniffer such as tcpdupm and ngrep to test your firewall settings. Conclusion: This post only list basic rules for new Linux users. You can create and build more complex rules. This requires good understanding of TCP/IP, Linux kernel tuning via sysctl.conf, and good knowledge of your own setup. Stay tuned for next topics: Stateful packet inspection. Using connection tracking helpers. Network address translation. Layer 2 filtering. Firewall testing tools. Dealing with VPNs, DNS, Web, Proxy, and other protocols. Sursa

Am facut un script php care sa ia automat toate linkurile de pe un canal de youtube: Luam de exemplu canalul Viso Trailers: Canalul utilizatorului trailers - YouTube Dam click pe videoclipuri. Mergem jos sa vedem cate pagini are acest canal. Observam ca are 59 de pagini. Copiem linkul din bara Canalul utilizatorului trailers - YouTube. <?php set_time_limit(0); $fisier = fopen('C:\xampp\htdocs\youtube.txt', 'a'); //jos trebuie setate numarul de pagini ex: de la 1 la 59 (59 fiind numarul de pagini pe care il are canalul) for($nr = 1; $nr <= 59; $nr++) { $date = file_get_contents('http://www.youtube.com/user/trailers/videos?sort=dd&view=u&page=' . $nr); //linkul de la canal cu pagini, fara numarul de pagini de la sfarsit $inceput = explode('data-video-ids="', $date); for($i = 1; $i < count($inceput); $i++) { $sfarsit = explode('" data-feature="thumbnail"', $inceput[$i]); $youtube = $sfarsit[0]; fwrite($fisier, 'http://www.youtube.com/watch?v=' . $youtube . "\r\n"); } } fclose($fisier); ?> Apoi va duceti pe http://videobb.com/upload.php Alegem remote upload, si de acolo alegem video hosting, din care alegem Youtube. Copiem cate 500 linkuri din fisier si le uploadam. (de ce doar 500? ca doar atat adminte siteul lor) Puteti sa il modificati sa salveze in alta parte, eu l-am rulat pe xampp. Trebuie sa admit, scriptul e copiat si modificat dupa alt script de al lui NYTRO!
