• What is a good solution for an adaptive iptables daemon?

  - by Matt

  I am running a series of web servers and already have a pretty good set of firewall rules set up, however I'm looking for something to monitor the traffic and add rules as needed. I have denyhosts monitoring for bad SSH logins, and that's great - but I'd love something I could apply to the whole machine that would help prevent bute force attacks against my web applications as well, and add rules to block IPs that display evidence of common attacks. I've seen APF, but it looks as though it hasn't been updated in several years. Is it still in use and would it be good for this? Also, what other solutions are out there that would manipulate iptables to behave in some adaptive fashion? I'm running Ubuntu Linux, if that helps.

• Setting up a externally facing server on Windows. How do i setup DNS/Nameservers?

  - by Jason Miesionczek

  So i have a domain name that i would like to host from my static ip internet connection. I have windows server 2008 r2 installed, and dns setup. The dns server is currently behind a firewall, and i have the appropriate rules to allow traffic to reach it. My question is, what entries do i need to create in the DNS so that i can have some nameservers to use at my domain registrar, so that the domain correctly points to the server? I know that most domains have nameservers like ns1.domain.com, ns2.domain.com, etc. What would i point those to in my DNS?

• ASA5500 series logging for management interface in transparent mode

  - by ANervousTwitch

  i have a cisco asa5520 in transparent mode. the interface is on the same subnet as some windows machines, which are generating a lot of broadcast traffic that is filling up the logs. is there any way to have it not log that its blocking those packets? its a bunch of these messages: "through-the-device packet to from management-only network is denied: udp src..." im also seeing some of those zeroconf requests that id like to drop logging for. i tried to just put a rule on the management interface, but apparently thats not allowed.

• What free OS should I use on my VPS?

  - by earlz

  Hello, I looked a bit but didn't see any duplicate of this so my question is which free(open source) OS do you use on servers and why do you use that OS? Background I have a VPS at Linode. There is a broad range of options for which OS I can put on it including both 32 and 64bit OSs. I just use it to run my small blog and for hosting random files. It's very low traffic. I have been using 64bit Arch Linux on my VPS and though I love the OS for general usage, for a server the constant breakage is troublesome. So I'm considering trying something new and am looking for suggestions.

• How can I avoid heroku stopping my dyno?

  - by iwein

  I build MVP's for clients regularly. Often I deploy on Heroku so they can see if the product works and demo it to prospects and investors. Then I have an application deployed on heroku, and it works like a charm, if not for one little thing. The app takes about 30 seconds to start up and heroku has the annoying habit of killing dyno's if they don't get traffic. My client is using the application for demo purposes now, so the load is extremely low and intermittent. I'm looking for a solution that is preferably: cost effective can be applied to multiple apps simultaneously What is the best way to avoid having the first request taking 30 seconds?

• Can a virtual mikrotik box bridge a hyper-v internal network with a hyper-v external network?

  - by mcfrosty

  I am trying to set up a Mikrotik router as a transparent firewall on my network. I got the machine working on a hardware MT box, but my boss wants the MT virtualized. I have been trying the set up where my virtual windows box talks to the Mikrotik via private or internal network on the Hyper-V host. I can get the two machines to talk, but as soon as I set up a bridge on the MT, all traffic ceases between the two. Is it possible to create a bridge for this purpose (having the MT silently in front of my firewalled server)? I could really use some help.

• connect to paltalk server using a proxy

  - by Navid

  Hi I want to use paltalk, which is a kind of chat software, but the ports that this applications uses are closed in my country. What I need to do is to use a proxy server. Unfortunately the software itself does not provide a proxy setting. I though it would be possible to run paltalk on an O.S. installed on a virtual machine (say virtualbox) and configure the network setting of virtual machine to direct all its traffic through a proxy on host Operating system, but I could not find a way to do so neither. can anyone please help me?

• Out Of Memory Error - Magento

  - by robobobobo

  Ok normally I understand when my server is giving me out of memory errors, but this one has me stumped! I'm running a magento based site, with one or two plugins in it and the rest is pretty basic. The site runs and loads fine wiht no issues. However in the backend - Configuration - Payment Methods it gives me the following out of memory error Fatal error: Out of memory (allocated 39059456) (tried to allocate 85 bytes) in ########/Varien/Simplexml/Element.php on line 84 Now this is where I'm confused..it's allocated more than it tried to allocate? Am I correct there? So how is it running out of memory? My server has 6Gb ram, an SSD and 2 CPU's running WHM with a few other low traffic sites on it. I set my php memory limit to 100mb, 1000mb and finally unlimited but all to no avail! I'm completely lost here, would really appreciate some expertise on this Cheers

• Wordpress Installation on Two Servers - Loadbalancing

  - by rihatum

  Hi All, I have to install wordpress (One Blog, one domain, for e.g. mycompany.com/blog) on two servers sharing one database on a different server, these two servers are behind a loadbalancer and the db would be on another server. We are planning this way due to high traffic. I have done standalone wordpress installations on a single server, on windows 2003, 2008 with IIS6, 7 etc I am just researching as to how would I implement this. What would be the steps to achieve this and upon searching I saw some posts regarding the wp-content/uploads directory to be synced at regular intervals ? your help much appreciated Thanks for reading

• Test-service on Internet for testing incoming INVITE

  - by leiflundgren

  I am trying to set up Asterisk at home. I think I'm having trouble configuring my firewall, so that inbound traffic is accepted, but I am not sure. I got the idea that, perhaps, there is a service out on the Internet, where I can, though a web-browser, initiate an incoming call, an INVITE. And then see the SIP-trace that the remote-part experience. Anyone know of such a service? Note. I have a SIP-PSTN provider so I can generate inbound calls. But I cannot see the SIP-logs from my provider...

• NAT Policy Inbound Source Problem on SonicWall TZ-210 with Multiple DSL Lines

  - by HK1

  We recently added three more DSL connections to our SonicWall TZ-210. My NAT Policies work fine as long as I leave them set with an inbound interface of X1, which hosts our original DSL connection. However, I'd like to change some of the NAT Policies to use inbound source/interface X2, X3, X4 or Any. In my initial tests, when I change one of the policies to use an inbound interface of X2, that port forward policy does not work at all. Traffic never makes it to the internal destination. What could be the problem?

• Blocking IP's Nginx behind proxy

  - by FunkyChicken

  I'm running a Nginx 1.2.4 webserver here, and I'm behind a proxy of my hoster to prevent ddos attacks. The downside of being behind this proxy is that I need to get the REAL IP information from an extra header. In PHP it works great by doing $_SERVER[HTTP_X_REAL_IP] for example. Now before I was behind this proxy of my hoster I had a very effective way of blocking certain IP's by doing this: include /etc/nginx/block.conf and to allow/deny IP's there. But now due to the proxy, Nginx sees all traffic coming from 1 IP. Is there a way I can get Nginx to read the IP's like how PHP does, with the X-REAL-IP header?

• Force a browser to load the 'https' edition of a website, not the 'http'?

  - by warren

  This is similar to this previous question, but I believe it's a bit different*. Sites like GMail support a preference that pushes all traffic through the SSL edition of the site rather than the plain-text protocol. For sites that don't offer such preferences (or ones that may, but I have been unable to find, like facebook), is there a way using only the browser (perhaps with a plugin or addon) to always try SSL first, and fall-back to plain-text iff SSL fails? Is that solution available on Windows, Mac OS X, and Linux? Just one? * The previous question was looking for external applications that would accomplish this goal.

• how limit the number of open TCP streams from same IP to a local port?

  - by JMW

  Hi, i would like to limit the number of concurrent open TCP streams from the the same IP to the server's (local) port. Let's say 4 concurrent conncetions. How can this be done with ip tables? the closest thing, that i've found was: In Apache, is there a way to limit the number of new connections per second/hour/day? iptables -A INPUT -p tcp --dport 80 -i eth0 -m state --state NEW -m recent --set iptables -A INPUT -p tcp --dport 80 -i eth0 -m state --state NEW -m recent --update --seconds 86400 --hitcount 100 -j REJECT But this limitation just messures the number of new connections over the time. This might be good for controlling HTTP traffic. But this is not a good solution for me, since my TCP streams usually have a lifetime between 5 minutes and 2 hours. thanks a lot in advance for any reply :)

• Route multiple subdomains on one external ip to multiple internal ips

  - by Abenil

  i have several subdomains(git.example.org, build.example.org, etc.), i have a router with an external ip and i have several virtual machines on a host computer with internal ips. Now i want to route git.example.org to internal ip 10.0.2.1 and build.example.org to internal ip 10.0.2.2. How can I do this? I setup in the Router that all traffic on port 80 is comming to my host computer with internal ip 10.0.2.3 and installed Squid on that computer. I added the following lines to the squid.conf file: cache_peer 10.0.2.1 parent 80 0 no-query originserver name=server_1 cache_peer_domain server_1 git.example.org cache_peer 10.0.2.2 parent 80 0 no-query originserver name=server_2 cache_peer_domain server_2 build.example.org But this is not working for me. :( Any help appreciated.

• load balancing two web servers each on two different isp's?

  - by Scott

  I have two ISP's that provide me hosting via apache / php / mysql. I am running drupal on them. On occasion the mysql server will go away (crash), so I was hoping to find a reasonable way to have a fail over, if server A SQL is down, all traffic is sent to server B. I know traditionally this is handled in DNS where a second alternate ip is given if there is a problem - or similar. But I do not have control over the isp, other than I can run php, perl and the usual apache stuff. Also, I have static ip's on each isp, and I can create dns entries (A/CNAME/TXT). So, I was hoping there might be a way for me to have a script that checks if drupal has a problem, and if so, somehow alter dns, or ? Or, any other ideas? (other than spending lots more $ on a better isp)

• Linux - Block ssh users from accessing other machines on the network

  - by Sam

  I have set up a virtual machine on my network for uni project development. I have 6 team members and I don't want them to SSH in and start sniffing my network traffic. I already have set the firewall on my W7 pcs to ignore any connection attempts from the Virtual Machine, but would like to go a step further and not allow any network access from the VM to other machines on my network. Team members will be access the VM by SSH. The only external port forwarded is to vm:22. The VM is running in VirtualBox on a bridged network connection. Running latest Debian. If someone could tell me how to do this I would be much obliged.

• Cheapest High Available Web Server [closed]

  - by xyz

  I would like to create a high-available setup (e.g. a small cluster) for a webserver, i.e. it will run Apache, PHP and MySQL. There will be between 2-8 small websites running with only very little traffic and workload. High availability is however very important. I don't want to be dependent on 1 datacenter, so there must be a minimum of 2 servers placed in different datacenters, and if one server goes down, the user must experience no or only a minimum of downtime - and no data loss. I have considered Amazon AWS using their Elastic Load Balancing, since it is possible to buy 2 EC2 instances in 2 availability zones and set up load balancing and RDS (Multi-AZ). However this seems rather expensive. Using the AWS price calculator http://calculator.s3.amazonaws.com/calc5.html it totals to 185$/month the first year (including the free tier). Are my calculations incorrect or is there a cheaper way to make this HA setup? Best regards

  I am working on a system having multiple servers. I am interested in monitoring some server specific data like CPU/memory usage, disk/filesystem usage, network traffic, system load etc. and some other my process specific data. What are available open source that can serve my purpose? If it provides to customize the parameter to be monitored and monitor your own data by creating plugin / agent. Any suggestions?

• Web Site Monitoring/Tracking Freeware

  - by jsmith

  I need to be able to track Web Sites visited on a computer and send them to an email address on a daily basis. Keylogger software seems like too much, I want something lightweight that simply monitors websites visited and forwards them on. I was hoping for freeware, but if it's cheap/simple and easy to use I'm willing to pay. I know similar questions have been asked about website traffic monitoring, but it's not quite the same thing, and I can't seem to find an answer to this question anywhere. Thank you ahead of time.

• scp to remote servers stalls, unable to isolate cause

  - by Rolf

  When I copy a large file (100+mb) to a remote server using scp it slows down from 2.7 mb/s to 100 kb/s and downward and then stalls. The problem is that I can't seem to isolate the problem. I've tried 2 different remote servers, using 2 local machines (1 osx, 1 windows/cygwin), using 2 different networks/isps and 2 different scp clients. All combinations give the problem except when I copy between the two remote servers (scp). Using wireshark I could not detect any traffic volume that would congest the network (although about 7 packets/sec with NBNS requests from the osx machine). What in the world could be going on? Given the combinations I've used there doesn't seem to be any overlap in the thing that could be causing the trouble.

• Apt Stalls When Using HTTP Sources

  - by UltraNurd

  I was getting some to me inexplicable behavior from apt-get/aptitude on an admittedly crusty old webserver. While it was otherwise running fine, as soon as I tried a package upgrade, after a downloading a few updates it would stall completely, then my SSH session hung (and I was unable to reconnect), thus requiring a hard restart. First, I switched to a different package source in /etc/apt/sources.list, but still got the same behavior. At this point I was assuming the NIC was dying in some weird way... but as soon as I changed the package source to use FTP instead of HTTP, everything worked fine, and I was able to upgrade. For now I'm not too concerned since I have an easy work around, but it implies that there's something very weird with my network setup, since it seems to be protocol (or port?) specific. I didn't think any of my NAT setup would affect outbound traffic, but I could be crazy. Any ideas what I should try to look for?

• Remote Software Solution that Acts as a Client

  - by Richard

  I am looking for something that I am not sure exists. I have a remote computer that will not allow incoming traffic due to ISP blocking of ports(basically double NAT situation that I am unable to get around). I am wondering if I have a computer acting as a client, is there any solution out there that will allow remote access to the computer. I do have other servers on the net that have static IP's that the computer could initiate a connection with. I am thinking of using Debian Linux, However computer is not built yet so OS is not overly important at this point.

• Windows Proxy Server advice

  - by Scott

  I have a webserver that currently has about 10 IP addresses. I have various clients that require a proxy server to route their internal traffic through. The load is not that great, so I'd like to have this ONE server act as a proxy server for 10 different clients, each client having their own unique IP on the server. The hardware is already setup, but I'm wondering what software solutions you guys recommend? I've looked at WinGate, Squid-Proxy, etc...but am pretty green with this. Maybe there's even a way to have Windows do this natively? I'm running Windows Server 2008, 32 bit.

• How to do port forwarding in D-link Glb802c?

  - by Manish

  I have some questions about port forwarding on my D-Link Router GLB-802C. For example: My local machine's IP is 117.1.1.81 My router's IP is 117.1.1.1 My Public (Web) IP is 117.16.1.1 My questions are: What will be my Global Address 'To'? What will be my Global Address 'From'? In Destination Port "From" and "To" what do I select in the drop down list and port no for forwarding HTTP traffic (for my website)? In Local Port, what do I select in drop down list and port no?
