• 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.

• 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

• 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

• 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.

• 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.

• 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?

• 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 :)

• 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?

• 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.

• 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.

• 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?

• 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...

• 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.

• 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.

• ASA Slow IPSec Performance

  - by Brent

  I have a IPSec link between two sites over ASA 5520s running 8.4(3) and I am getting extremly poor performance when traffic passes over the VPN. CPU on the device is 13%, Memory at 408 MB, and active VPN sessions 2 so the load on the device is particularly low. Screenshot of wireshark file transfer between the two hosts over the VPN: The large amount of Header checksum failures is alarming, but I am not sure what to check now. I perf is showing around 4-5 Mbit/sec with differing TCP window sizes. Show Run on the ASA http://pastebin.com/uKM4Jh76 Show cry accelerator stats http://pastebin.com/xQahnqK3

• 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?

• VPN service for 4in6

  - by Deshene

  I have a local network with internet access. But unfortunately IPv4 internet connection speed is limited to 1mbps, which is realy sad. Fortunately I have a native IPv6, and there is no connection speed limit over IPv6. So, in order to get a good internet connection I made a plan: connect to the VPN-service over IPv6, and pass all IPv4 traffic through IPv6 tunnel, or something like that, I think you get the idea. I suggested to use service like HideMyAss.com, but unfortunately they don't support IPv6. The question is: Is there any existing VPN service that will make my dreams come true, and is easy to use, which I could connect over PPTP or OpenVPN (I want to set up connection to VPN in my router settings).

• Redundant Router and Load Balancing vs. DDoS attack

  - by colgatta

  With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?

• startup cassandra layout

  - by davidkomer

  We've got a relatively low-traffic site (~1K pageviews/day) hosted on a single server, and expect it to grow significantly over the next few years. I'm thinking of moving over to Rackspace CloudServer or EC2 and firing up 3 nodes (all on CentOS): 2 x Web (Apache) - with loadbalancer 1 x MySQL (for the Wordpress powered part) The question is where to put Cassandra right now... Should it sit on each Web node, or the MySQL node? My thought right now is to put it on Web nodes. It's my understanding that Cassandra has the benefits of fault-tolerance (i.e. if we take a node down, the site is still operational). So even with only 2 nodes, we'd have that benefit as opposed to just putting it on the MySQL node. Also, as we scale up and add another node, a cassandra instance can come along with it and the php can always run its queries on localhost. Is this a good idea?

• EC2 hostname ubuntu and ejabberd

  - by aelbaz

  I have questions related to the host name in Ubuntu EC2 instances. I have a IPS elastics for hosts that want to be seen from the internet and I have pointed out in the DNS entries with the computer name to those ips. For example, for elastic IP 11.11.11.11 DNS I added my computer name www.example.com. But I also want to rename the machines which they have, because it is a parameter of the service running on them (ejabberd server). EC2 instances are restarted when changing the host name, and seen on the client requesting dhcp hostname to dhcp Amazon. My question is ... What is the safest method to change the hostname: dhcp client modify, insert the command in rc.local, etc. ..? Could I have a problem with the internal resolution of traffic between EC2 instances? thanks

• 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 RRAS multi-network routing

  - by Brent Pabst

  I am looking for advice, comments and suggestions from anyone who has used Windows RRAS (2008 R2 Pref.) as the primary routers for our multiple offices. We have multiple physical office locations and are looking into utilizing Windows Server 2008 R2 Core as redundant Active/Active routers/gateways for our network as opposed to a physical router from Cisco or Juniper, it costs a lot less! Any problems, issues or documentation anyone would recommend? We will still most likely have a firewall on the edge but the majority of our traffic will be inter-office with some external services. We will be using multiple Class B networks across our two offices.
