develop small linux firmware for a 4MB ROM / 16MB RAM Wifi router with Netfilter , iptables & WiFidog

We host a server with 13 WordPress sites on it and it is being targeted for a DDoS attack. We have moved the websites to a new server and the attacks followed. We need to determine what is the source and method of the attack and then harden the server to ensure that those are blocked at the firewall and do not bring the server down. We run a firewall (iptables) and fail2ban.

On our anycasted network we need the ability to listen and send traffic over to a remote host via GRE tunnels. This needs to be done without NAT routing (IPTables, etc.) to prevent bottlenecks and needs to be done via a per-listening IP method (or per sub-interface like eth0:10, etc.). It also needs to store the amount of bandwidth used and be able to clear that bandwidth stat on demand without rebooting the program.

Hi, I am looking for a method to whitelist my users IP on multiple servers from a master server. The master server will use a client portal, that has the option to add,remove and modify the client's IP address. Similar to Hidemyvpn or IronSocket. I am looking for someone who can build out the workflow, scripts (bash,python,php, whatever) and intergrate it will my billin system. Ideal workflow: 1) Client enters IP address into website and clicks update. 2) The script will either run it at that moment OR batch it to run in 2 minutes. There is a good chance that multiple users may enter whitelist their IP address at the same time. 3) The script will then reach out to each of my servers via a secure method and perform the update (add/remove/modify). 4) Once the script is d...

Setup Free PBX on a fresh Ubunto 14.04 server. The server is running on DigitalOcean and the image used is a generic Ubuntu 14.04 image.

Once done I will give you details for a DID number (incoming trunk) and a SIP provider (outgoing trunk). You would have to setup both trunks and connect them to an extension for demo purposes. I expect all incoming calls to forward to my extension on Zoiper and all outgoing calls from my Zoiper should use the SIP provider. This has to work flawlessly. CDR reporting should be up and running. Call recording needs to be enabled on b...

As per the attached file. I would like to use iptables to redirect a service to a web portal for registration/authorisation. The IP addresses will be used to authorise access to the service. The addresses will be on a file. Details as follows: User tries to access the service on port 53, if authorised (ie if on the attached file in lets say /usr/local/etc/) they are granted unconditional access, if not redirected to a portal eg 3.3.3.3 port 80 (3.3.3.3:80). Everything else happens there including updating the attached file so you dont have to worry about how that happens. - file will be comma delimited in the following format : username,ipv4 address eg markj, (see attached sample file) - all requests to a specific port (53) will be 'matched / against the file lets
