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 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.

I have a website that is hosted on Rackspace Cloud. It is a custom php CMS. Rackspace says that the site has been compromised. Their comments are below: Your server does appear to be compromised and making outbound DNS requests to our DNS servers on port 53. While this would normally be ok, it seems that the amount of traffic is high which has potential to get your server blocked from our DNS resolvers. You can add this line (iptables -A OUTPUT -o eth0 --dport 53 -j DROP) to your iptables firewall rules to prevent this but, it will cause you to be unable to request DNS unless you remove it or turn off your firewall (not recommended). The client went ahead and added this line to the iptables as a temporary fix but it is just a bandaid fix and is causing the site to not be able to send emails. I need this job completed within 48 hours.

We need a highly available firewall software/service that checks first 75 bytes of each message (layer7), logs it and only if certain string pattern matching criteria is met, forwards the remainder of the packet (bytes 76 and onwards) to its intended destination IP address. l7-filter seems like a good match, the service will run on ubuntu 14.04.

Need help securing our 3 servers and fixing some problems. Server 1: We're not able to connect to the server via SSH and the email server is not responding. This server hosts a custom website and back office application that are both unaffected by the current issues. Since the problems started we noticed a large spike in inbound bandwidth on this server (prior to the issue, 98% of our traffic was outbound & 2% inbound, now overall traffic is doubled with inbound & outbound @ 50/50). 1. Look into the SSH issue and if it could be a custom SSH port, or a firewall rule that is blocking the connection. 2. Assess if iptables blocked SSH and if there are any current hacks 3. Fix the current issues with ssh & email Server Config: - dedicated linux/centos server running apache - custom api, email server, php - csf firewall Server 2: We noticed a large spike in traffic on this server and found one of our wordpress websites was hacked and is hosting torrents downloads. 1.

Hi, I have two VPC's on AWS (with CIDRS 172.14.0.0/16 and 20.0.0.0/16) that are peering. I need to do 1 to 1 NAT from instances on 20.0.0.0/16 to specific ec2 instances on 172.14.0.0/16 All the traffic is private, both VPC and its subnets do not have internet connectivity. Currently I have an EC2 instance with private IP 20.0.0.22 where I do need to set properly iptables to do this NAT. Basically I need iptables guidance to configure : all the traffic that arrives into 20.0.0.22 gets forwarded to 172.14.0.22.
