I need someone who can preform various tasks on my linux web servers that are running web based proxies. I'm specifically looking for someone who is able to install mod_ruid2 to work with Apache and track down my current bottleneck. But other tasks might include: firewall setup and security against minor DOS attacks or bots trying to scrap content through the proxy. Good communication is a must.

I am working on a project that allows wired users get redirected to a web portal for web base authentication or simply accepting terms and conditions. I try to explain my project as details as possible. Please let me know if you can do any part of this project. Here is the project: Current implementation : My gateway is a linux(Debian) box running DHCP server using dnsmasq. The linux server has two interfaces; one to Internet one to the LAN (let say eth0 for LAN and eth1 for Internet). When users turn on their PCs they get IP address from the Linux box and their traffic will be NATed (using iptables) for Internet access. What I want: when they get IP address , their traffic get redirected to an external web portal which is on the internet. For example, I want their traffic gets redirected to myownportal.com for authentication or simply accepting terms and conditions. This happens when they open a browser and try to open any websites. This is similar to linux hotspot solutions lik...

I have a Dialer and a IP-PBX that need to send and receive Sip traffic independently from the same Sip Provider. The IP-PBX is currently working, I now need to route the Dialer to a second External Nic on the firewall so we and the Sip Provider can distinguish Sip traffic. External interfaces are eth0(xxx.xxx.xxx.161) and eth2(xxx.xxx.xxx.167. So the default Gateway is eth0 and we need the Dialer to go out eth2(xxx.xxx.xxx.167) and receive Established, Related traffic back from eth2 to the Dialer. Sip Provider is using Port: 5060 and for the second connection they can use 5070 if that will help.

Looking for someone TODAY to configure two Router OS machines. It's really simple stuff .... In China we have 3 WAN connections and 6 other LAN connections. Each LAN connection needs to be routed via a separate WAN. (eg, eth4~6 to route to wan1/eth1 -- then eth7~8 to route through eth2/wan2 -- then ) All P2P (torrent) traffic needs to be blocked on eth 1~2 (wan1 & 2) but since we use a software called BitTorrent SYNC (professional file syncing platform), all local computers need to block the P2P SYNC connection. There is a server SYNC on eth9 that these computers will SYNC locally with, and that SYNC connection needs to route through eth3 (eth3/wan3 will allow the P2P traffic and all internal traffic needs to have P2P traffic). Also, we need a dedicated VPN Link setup between one WAN port (eth3/wan3) to another MikroTik router in the USA. I'll be available all day China time to assist in the configuration, we can use remote desktop or QQ to connect to the routers via Winbox....

I need a system administrator who is available when needed. There will not be much work on a consistent basis, but you will definitely have hours throughout the week to check on things, give me explanations on what happened and where, along with other maintenance stuff. The biggest reason I need you is that I have a very large system that runs with iptables that was created by my old system admin. I need you to learn this system and understand how it works exactly, so if it ever goes down or stops working you can go in and fix things or know what's going on. Price is not an issue if you know your system administration.... I only want someone who is professional and can jump right in and start learning that large system. Freelancer must be fairly good with Perl as the automation of the iptables is controlled by Perl, along with some other Perl scripts. Knowledge of Perl is required! I run a distributed network of proxies used by customers for SEO link-building efforts. My developer...

I have an existing server that runs an older version of Apache Solr. I have a new server that has a newer version of Java. I need the same version of Solr to be setup on the new server if possible. I believe the version of Solr on the existing server has also been modified and these modifications will need to be migrated and documented. As well, the Solr data store will need to be migrated to the new server. If the older version of Solr doesn't work with the newer version of Java, we can downgrade Java or upgrade Solr.

I need someone to give me a few hours support with some of the more complex parts of Sophos UTM -Setting up captive portal so that a user is mapped to a device (not on wireless, on the LAN) -Explaining what the masquerading section is under NAT. It appears to be used to define the outbound WAN link and IP address to use. However my experiments in flicking people between different WAN links has not worked. (is there some caching of these settings so it is not instant - like states in the states table?) -Assistance in best practices to define groups and users and then set up traffic shaping rules for groups and exceptions for users so that it is easy for someone to manage. -Assistance in best practices for naming definitions, hosts, etc so that it is easier to know what stuff is in different interfaces. There is probably some more.
