• Multi sim GSM modem or alternative

  - by Ando

  I'm trying to administer the SMS trafic of my businesss centrally through a web portal. In Europe (except UK) we don't have a numbers/SMS trafic provider like Twilio or Clickatell, nor any build in way to administer the SMS traffic for a number via http, so I will have to buy the long numbers and administer the SMS traffic myself. For this I was looking into a hardware solution for hosting all my SIM cards - I have like 400 sims cards (= numbers). I saw that GSM modems might fit in but they don't seem to scale up very well. Could you recommend me a GSM modem? If this is not the best way to approach this, what would my alternatives be? Thanks in advance

• Recommendations for VMWare web server environment with load balancer.

  - by Ben

  We run IIS websites on a VMWare production server that pull image content and video content from a separate IIS instance on another server (media server). The media calls (images and video) are straight http:// calls and not using a streaming application. During peak traffic periods, we clone the production server five times and have a load balancer distribute traffic to all five production servers. The media server does not get ramped up. We noticed that the processing and resources on the media server gets very taxed during this period. Would it make sense to run the IIS instance for the media server locally on the production server and have it cloned with the production servers, then have a rule on the load balancer negotiating these media calls from the website? Would it be better to allocate more resources (memory and CPUs) to the media server VM and not clone it with the production servers? Recommendations are sincerely appreciated.

• setting up delegate or smtp forwarding

  - by cotiso

  for work we have a remote dedicated server to run our webservice that also runs our email services, at home(comcast residential internet) i cannot send mail using the dedicated server's SMTP, comcast spits back a error saying i can only use their SMTP server for sending mail at work(comcast business internet) we can use our dedicated server for sending mail with no problem so i set up a box at work to forward smtp traffic, i'm new to all this networking stuff by the way i used delegate to forward smtp traffic, can someone point me in the right direction on how to use this program(delegate) to fix our issue the delegate command i used to test is : delegated -P25 SERVER="smtp://dedicated.server.com:25" PERMIT=":::" -v i also opened up port 25 on the router so it points to my boxes ip are there any other ways to fool comcast into thinking im using my works ip to send mail, my coworkers and i are unable to send mail from home for some time now thanks

• Java application server behind IIS 7.5 on Windows Server 2008

  - by perissf

  I have a Java application server (GlassFish, indeed, but the problem is the same for any other application server, I guess), running on port 8080. And I have IIS 7.5 listening on port 80 as by default configuration. I want to avoid people typing the port because it's unprofessional. So I want that when somebody types http://myserver the traffic is directed to IIS. And this is how it already works now. But I also want that when somebody types http://myserver/java the traffic is directed to port 8080 and consequently my GlassFish splash screen is displayed. If I have deployed an application on GlassFish under context root app1, typing http://myserver/java/app1 should access the application. How can I do this? I have tried with adding some rules with the URL Rewrite utility from IIS7.5 UI, but this shows the port after the rule has rewritten the url, and I want to avoid it.

• windows firewall and network location switch after establishing a vpn connection

  - by Konrads

  I am looking for a reasonable solution for network location switching after VPN connection is established for Windows 7. The scenario is as follows: For location public (employee plugging in his laptop in hotel, public wi-fi,etc) all inbound connections are restricted, only outbound VPN + www is enabled. Employee then initiates a VPN connection, VPN pushes routes to 10.0.0.0/8 subnet Now I would like to have lax security rules for traffic from/to 10.0.0.0/8 that comes through the VPN interface, while still protecting the laptop from traffic that comes via uplink interface as if it was private. How to achieve this switching and duality? One option I see is switching to IPSec...

• Should I Use PHP as FastCGI?

  - by Synetech inc.

  Hi, I am running an Apache webserver on my Windows machine. It is not generally a public server (most of the little bit of traffic comes from the machine itself, and most of the public traffic comes from crawlers). Basically, it is mostly just for use as a test-bed, development system. I have read about how running PHP as FastCGI is better (ie faster and more stable) than as an Apache module. However, I really don’t like the idea of multiple PHP.exe processes (I don’t like that Apache has two processes and I’m not even too thrilled with Chromium’s multi-process model). So I’m wondering if it would be worthwhile to change PHP to FastCGI for this scenario. If it is, how would I configure it? Pretty much all of the information I have seen has been either for non-Windows or for IIS. As I said, I’m running Windows+Apache. Thanks a lot.

• Hosting 3 domains on 3 PC (1 domain per PC) with only 1 static IP address

  - by StealthRT

  Hey all i am trying to figure this out here. I have 3 PC's that are hooked into my router which i have a static IP for. I am currently hosting a web site (ex: blah1.com) on the 1st PC but have yet to connect PC 2 and 3 up to the network. That one PC thats online is using port 77. I direct all 80 traffic to port 77 using that servers IP address (192.168.x.xxx) My question is, how can i direct traffic for my other 2 domains (ex: blah2.com and blah3.com) to the 2 individual PC's (ip's) as i already am doing with the 1st PC if i can only use one port 80 to direct taffic to the website in?

• Blocking a country (mass iP Ranges), best practice for the actual block

  - by kwiksand

  Hi all, This question has obviously been asked many times in many different forms, but I can't find an actual answer to the specific plan I've got. We run a popular European Commercial deals site, and are getting a large amount of incoming registrations/traffic from countries who cannot even take part in the deals we offer (and many of the retailers aren't even known outside Western Europe). I've identified the problem area to block a lot of this traffic, but (as expected) there are thousands of ip ranges required. My question now (finally!). On a test server, I created a script to block each range within iptables, but the amount of time it took to add the rules was large, and then iptables was unresponsive after this (especially when attempting a iptables -L). What is the most efficient way of blocking large numbers of ip ranges: iptables? Or a plugin where I can preload them efficiantly? hosts.deny? .htaccess (nasty as I'd be running it in apache on every load balanced web server)? Cheers

• VPN, routing, specified application

  - by Adrian

  Details: eth0 = current internet port pptp1 = VPN connection, if I connect to my provider, he give me an IP address, which is accessible from the internet. This is what I need. I want to connect through this IP back to my PC. I want to keep my primary internet connection (eth0) on my PC for all traffic, but route traffic to VPN for specified application/or port, to access application/port from the IP, which I given from the pptp provider. Huhh? Difficult but, it is possible? If yes, how? Incoming port will be always: 33340 Outgoing port can be change, but usually it is 33330

• Public Facing Recursive DNS Servers - iptables rules

  - by David Schwartz

  We run public-facing recursive DNS servers on Linux machines. We've been used for DNS amplification attacks. Are there any recommended iptables rules that would help mitigate these attacks? The obvious solution is just to limit outbound DNS packets to a certain traffic level. But I was hoping to find something a little bit more clever so that an attack just blocks off traffic to the victim IP address. I've searched for advice and suggestions, but they all seem to be "don't run public-facing recursive name servers". Unfortunately, we are backed into a situation where things that are not easy to change will break if we don't do so, and this is due to decisions made more than a decade ago before these attacks were an issue.

• Elastic Load Balancer & SSL termination

  - by Aaron Scruggs

  I am setting up a Rails app on AWS that: 1) all traffic must ssl encrypted 2) will highly fluctuate in traffic on a weekly basis 3) will by maintained by someone that is a stronger coder than sysadmin, but will be responsible for both I am thinking that SSL termination on an elastic load balancer backed by small ec2 instances running nginx and unicorn A small subset of the requests will take longer than 10s, because of this I am also debating using 'thin' instead of 'unicorn'. My question is this: Is this sane? I am stepping into a quagmire of cost, maintainability, security or performance problems?

• Smart subdomain routing via reverse proxy

  - by Trevor Hartman

  I have two servers on my home network: OSX Server and an Ubuntu Server. I'd love to have external subdomains osx.mydomain.com point to osx and ubuntu.mydomain.com point to ubuntu. I know the normal way to do this is to have a static external IP address for each, but that's not an option as this is just my home setup. My question is: is there a way to do this with some reverse proxy trickery? OSX is currently the default entry point for all traffic. I was able to setup a reverse proxy on OSX for ubuntu.mydomain.com on port 80, so web traffic was correctly being proxied to my ubuntu. I'd like to ssh and do a bunch of other stuff though!

• Can a device (WAP or switch) be configured as an 802.1x supplicant?

  - by Allan Ross

  We are looking at implementing 802.1x on a wired/wireless network. What I am looking for is a device that can act as a supplicant and once authenticated on the network, is able to pass traffic from any downstream connected device. The point of doing this would be to allow a properly pre-configured device to be provided to a client user who could then connect any device on the downstream side of the device. We will be able to manage the aggregate traffic on the device without concern for what is connected on the far side. Am I dreaming; does every device out there support this and I just don't know it or is reality fall somewhere in the middle?

• HA Proxy and Disaster Recovery - Only access server if others are down?

  - by ben2004uk

  Why I expect this is not the best way to solve the problem, I got thinking tonight. I'm thinking about geo-locating servers. Given we have a load balancer + two servers to handle traffic in NA (North America) and one server in the EU. If the two US servers die, is it possible to get HAProxy to direct traffic automatically to the EU one. However, I don't want to use a roundrobin approach for the EU - just the two US ones. The EU should only be hit when the other two are down. Does anyone know how to configure HAProxy to do this? Thanks Ben

• Is there any way to limit my Internet connection to a per program basis?

  - by Igoru

  My Linux connection is REALLY free. I live in Brazil, so where I live I can only have 1 Mbit/s. Yes I know it's sad, but it's not the point. Everytime I'm updating my Ubuntu 9.04 or downloading something, it does eat all my bandwidth. Like, while update-manager is downloading the packages, I can see by netspeed applet in my panel that the incoming traffic goes to 110 kB/s. And then, my Emesene suddenly goes disconnected, and I can't navigate. As you can imagine, I can't use my Internet connection again until the packages are all downloaded or I cancel the update in the middle. As I said, same thing happens when I'm dowloading something, but less intrusive and immediate. The question is: is there any way to limit that APT/downloads traffic to some way I can still use my other Internet services, or to reserve some bandwidth for common navigation tasks (like we have on Windows, but I forgot this thing's name, it's like "something packages".

• How do I configure pfsense as an outbound VPN client?

  - by Avery Chan

  We use pfsense as a router/firewall. Because we're based in China, it is useful for us to have VPN access for all our internal clients. Instead of each individual client connecting to a VPN server stateside, I'd like to configure pfsense as a VPN client and have all the network traffic be routed through it. Most of the posts I've seen regarding pfsense and VPN are concerning connecting to the LAN from outside; this is not what I want to do. Another option would be for an SSH tunnel to be initiated on the pfsense box with the LAN traffic routed through it. How do I configure pfsense to be able to do either of these? One huge caveat is that OpenVPN cannot be used. The solution I am looking for needs to use one of the other VPN protocols.

• Measuring cumulative network statistics per user or per process

  - by zsimpson

  I've been googling for hours -- Under Linux I want to know the cumulative bytes sent and received by user or by process over all ip protocols. The best I've found in my searches is that it's possible to use iptables to mark packets for a user, for example: iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner test -j MARK --set-mark 1 It appears that "tc" can then shape traffic with that but I just want the statistic -- I don't want to shape the traffic. I want something like: "user U has transmitted used XMB since time Y". I can't figure out how to get statistics from these marked packets. Also, I've looked at nethogs but they seem to be measuring the instantaneous flow and I need cumulative counts. Anyone have ideas?

• Help with Apache rewriteengine rules

  - by Vinay

  Hello - I am trying to write a simple rewrite rule using the rewriteengine in apache. I want to redirect all traffic destined to a website unless the traffic originates from a specific IP address and the URI contains two specific strings. RewriteEngine On RewriteLog /var/log/apache2/rewrite_kudithipudi.log RewriteLogLevel 1 RewriteCond %{REMOTE_ADDR} ^199\.27\.130\.105 RewriteCond %{REQUEST_URI} !/StringOne [NC, OR] RewriteCond %{REQUEST_URI} !/StringTwo [NC] RewriteRule ^/(.*) http://www.google.com [R=302,L] I put these statements in my virtual host configuration. But the rewriteengine seems to be redirect all requests, whether they match the condition or not. Am I missing something? Thank you. Vinay.

• multiple vlans routed on one nic? trunk?General? or Access?

  - by Aceth

  ok for the last week I've tried racking my head around this... I have a SRW208P with 802.1q support, and a virtual endian appliance. I would like to be able to have 3 vlans having everything routed through the endian appliance.. i.e. The Virtual server has 2 bridged NIC's to the switch. This is where I'm getting confused .. On the 8 port switch I've got the 3 vlans set up ok (all being untagged as they are not going to be vlan aware), it's the port I'm connecting the endian firewall to the switch I'm having trouble with (second nic goes to the adsl modem and NAT'd) Is it meant to be a trunk, "Genereal" or "Access" then untagged or tagged? the end goal is to have vlan traffic routing through the single NIC and have endian route vlan traffic according to the rules. Any one have any ideas on the cisco small business stuff? Thanks

• SSH Socks Proxy wiith iptables REDIRECT

  - by Radium

  I have googled and haven`t found the answer on my question. Help me please. There are two servers: serverA with public IP 12.0.0.10 and an private IP 10.0.0.5 serverB with public IP 20.0.0.11 I have setup SOCKS proxy on serverB to serverA: ssh -D20.0.0.11:2222 [email protected] So when on my local machine in a browser i specify SOCKS proxy 20.0.0.11:2222 (serverB:2222) as external IP while browsing i get 12.0.0.10 (serverA IP). That is ok. As well if i go onto http://10.0.0.5 (serverA private IP) it is also reachable. That is what i need. I want to make servers A private IP to be available through servers B public IP on certain ports but without specifying SOCKS in my browser. I could use ssh port forward but the problem is - i need to forward many ports and do not know which exactly - i know only the range. So when i connect to 20.0.0.11 to any port , for example, from 3000:4000 range, i want that traffic to be redirected to 10.0.0.5 on the same port. That is why i`ve decided maybe SOCKS proxy via SSH and iptables REDIRECT could help me. Client - serverBPublicIP (any port from range 3000:4000) - serverAPublicIP - serverAPrivateIP (the port was requested on serverBPublicIP) On serverB i do: ssh -D20.0.0.11:2222 [email protected] iptables -t nat -A PREROUTING -d 20.0.0.11 -p tcp --dport 3000:4000 -j REDIRECT --to-port 2222 But that does not work - when i telnet on 20.0.0.11:3001 for example i do not see any proxied traffic on the serverA. What should i do else? I have tried tcpsocks like this (in example i am telneting to 20.0.0.11:3001) Client -> 20.0.0.11:3001 -> iptables REDIRECT from 3001 --to-port 1111 -> tcpsocks from 1111 to 2222 -> SOCKS proxy from serverB to serverA on port 2222 -> serverA But i do not know what to do with the traffic on serverA. How to route it to its private IP. Help me please. I know, VPN removes all the hell i am trying to create, but i have no ability to use tun/tap device. It is disabled.

• Can admins monitor my activity locally even when I use a VPN?

  - by Arjun Create

  My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

• On Mikrotik RouterOS, is it possible to get Netflow information from a bridged connection?

  - by Tim

  I have a RouterOS box set up to bridge two ethernet connections. I have use-ip-firewall=yes in the bridge configuration, so that the ports go through the firewall. I've enabled netflow reporting via ip/traffic-flow, but the only packets I see reported are broadcast and multicast packets, not the packets that are flowing through the bridge. The documentation indicates that traffic flow logging happens after firewall processing and that it won't work with bridged connections by default, but I would have thought that use-ip-firewall=yes ought to address this. Is it possible to make this work somehow?

• Firewalling a Cisco ASA Split tunnel

  - by dunxd

  I have a Cisco ASA 5510 at head office, and Cisco ASA 5505 in remote offices. The remote offices are connected over a split tunnelled VPN - the ASA 5505s use "Easy VPN" Client type VPN in Network Extension Mode (NEM). I'd like to set firewall rules for the non-tunnelled traffic only. Traffic over the VPN to head office should not have any firewall rules applied. I might want to apply different firewall rules to different remote offices. All the documentation I have been able to find assumes the Client VPN is a software endpoint, and all the configuration is done at the 5510. When using a Cisco 5505 as the VPN client, is it possible to configure any firewalling at the Client end, or does it all have to come from the 5510? Are there any other issues to look out for when split-tunnelling a VPN by this method?

• IIS Reverse Proxy support for multiple protocols

  - by Abraxas

  I have a server 2012 machine running IIS. It's in my DMZ and I would like to use it to do reverse proxy for several services. I can get it to route traffic on port 80 to 2 separate internal servers running web apps but there are some issues when I try to forward SSH (not port 80/443) and then when I try to forward OWA (Micrsoft exchange's 'webmail' services) to the internal mail server I run in to issues with guides (like this: http://blogs.technet.com/b/exchange/archive/2013/07/19/reverse-proxy-for-exchange-server-2013-using-iis-arr-part-1.aspx) when they say to have all traffic forwarded to the server farm created for OWA. My question for you all is this - given that there is no more Threat Management Gateway (only runs on server 2008) and ISA 2006 is also dead - is it possible to support multiple types of reverse proxies with different protocols (ftp, ssh, web, ssl-web) in IIS, or would it be better to install a different DMZ OS like a nginx server and use linux firewalls + nginx reverse proxy? Thanks for any help!

• Dual-WAN router

  - by aix

  I am looking for a router that would fit the following requirements: Two WAN interfaces: the primary is PPPoE, the secondary will link to a GigE port on another router (a 100Mbps link will suffice); Two (ideally four) GigE LAN ports; No requirement for a firewall; No requirement for Wi-Fi; Inexpensive. The plan for the two WAN interfaces is as follows. All outbound traffic will go to the primary, with exceptions based on destination IP/subnet or possibly on src+dest IPs/subnets. Such exceptions should be routed to the secondary. It would be very nice if, should the primary go down, the secondary would automatically take over for all outbound traffic. I am reasonably sure that I can put something together based on dd-wrt. However, I'd like to hear from you what alternatives are out there (especially something easier to set up for my use case, even if it means paying more for the hardware.)
