• MediaTemple Django Bad Gateway

  - by Eeyore

  I have a site running on GS server on MediaTemple. It's Django/PostgreSQL setup. For some reason from time to time I get Bad Gateway error and I can't figure out what's causing it. What can cause this error? What else can I do to find the cause of the problem? url.access-deny = ( "~", ".inc" ) fastcgi.server = ( "/main.fcgi" => ( "main" => ( "socket" => "/var/tmp/" + appname + ".sock", # don't change this "check-local" => "disable", ) ) ) alias.url = ( "/media/" => "/home/xxx/data/python/django/django/contrib/admin/media/", "/static/" => "/home/xxx/containers/django/site/static/", ) url.rewrite-once = ( "^(/media.*)$" => "$1", "^(/static.*)$" => "$1", "^/favicon\.ico$" => "/media/favicon.ico", "^(/.*)$" => "/main.fcgi$1", ) server.error-handler-404 = "/main.fcgi"

• Load Testing a Security/Gateway Appliance

  - by Joel Coel

  In a couple weeks I will load testing a security/gateway appliance. We're a small residential college, and that "residential" means the traffic moving through the appliance is a bit like the Wild West. We have everything from Facebook to World of Warcraft, BitTorrent to Netflix, or Halo to YouTube... basically anything you might find in the home of a high-school or college aged person. Somewhere in there some real academic work gets done as well. We rely on our current appliance for traffic shaping, antivirus, malware filtering, intrusion detection on our servers, logging and abuse reporting, and even some content filtering. All this puts a decent load when we have students around, and I'm concerned about the ability of the new candidate to keep up. On paper it should handle things, but I'm worried. Prior experience is that vendors greatly over-report what an appliance can handle. The product also includes a licensed session limit, and I'm also worried that just a few misbehaving students could unwittingly bring us to that limit and cause service disruptions. I need to know this will work for our campus in order to commit to it. Going a performance level higher in that product takes the pricing way out of line with what we expect and have done in the past. What I need is a good way to load test this guy. My problem is that our current level of summer traffic is less than one percent of what it will be when students come back just six weeks from now. Any ideas on how to really stress this thing and see what it can do, in a way that will give me some clear ideas o. How that will scale for our campus? For the curious, I'm looking at a Watchguard 515, but it could be anything. If I were evaluating a competitor, I'd ask the same question.

• openvpn& iptables -- portforwarding and gateway

  - by Smith.Lai

  The problem is similar to this scenario: iptables rule still take effect after deleted Scenario: There are several clients(C1~C10) providing some services, such as SSH,HTTP..... The clients are actually a personal computer behind NAT. Their IP might be 192.168.0.x For easily access these machines through internet, I built a OpenVPN server(S1). All the C1~C10 connect to S1 with VPN address 10.8.0.x If A user(U1) wanna access C1 SSH through internet, he can connect to S1 with port "55555", and S1 port forward 55555 to 10.8.0.6:22 echo 1 /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 55555 -j DNAT --to-destination 10.8.0.6:22 It works well until I mark the following in the openvpn server.conf: I marked this because I think this will make all connection go through S1 ;push "redirect-gateway" |-------(NAT)--------| (C1)--| (INTERNET)----(U1) |-----(VPN)----(S1)--| The C1~C10 have their own path to access internet resource through NAT . The server loading would be heavy if all C1~C10 connection go through S1 (for example, C1 is sending data to C2, or C1 is downloading data from a FTP site). Is there a way to solve this quandary?

• transparent git-svn gateway

  - by azatoth

  Currently we have an subversion repository with the following layout: /trunc /group1 /proj1 /proj2 group2 /proj3 /etc.. /tags /group1 /proj1 /proj2 group2 /proj3 /etc.. /branch /anything temporary I believe this is an rather bad layout, but at the moment it's difficult to change it fully. Personally I dislike subversion, due mostly the long time it takes to check history, and also that branching and merging are cumbersome etc. so I really want to use git instead. Sadly we cant just switch to git as the mental capacity for some might be to overwhelming, so I was looking into git-svn to see if I could practically use that to solve the issue. Sadly that directly ends up in a bad situation as I want to break down each project into one git repo, and I don't want to have to recreate the git-svn checkout on each computer I work on. so I though perhaps there is an possibility to create some sort of transparent git ?? svn proxy/gateway, so that an push to that repo "commits" to the svn repo, and an commit to the svn repo updates the git repo. Google hasn't been my friend, have only found generic usage help to use git-svn, so I ask you if you have some good ideas to accomplish this.

• Choosing gateway router/firewall for small datacenter network [closed]

  - by rvs

  I'm choosing a gateway router/firewall for small internal network for medium-sized web service. Currently there are 5 servers in internal network, up to 50 http(s) requests/second, up to 1000 simultaneous connections, uplink is 100 Mbit. So, network is relatively small and not very busy and we don't like to buy some pricey monster like cisco or jupiper for this site. Instead we'd like to buy two affordable devices (one for spare), which can handle our workload now and some time in future (it might be up to 2x more in 1 year). I had some experience with Sonicwall NSA, but it seems to be too complex for this site (we don't need most of its features) and even too pricey when buying two of them. So, after some research I've come up with following options: Netgear Prosecure UTM Series (probably UTM25) Zyxel ZyWall Series (USG100 or USG200) Sonicwall TZ 210 Is this a good idea? All of the above seems to be more office products, not datacenter ones. Or we should stick with Sonicwall NSA? Does anyone have any hands-on experience with this models? Maybe some other advices? Thanks.

• Already have Merchant Account, what info will my Gateway need?

  - by Anonymous Coward

  I have a client who already has a merchant account for their physical store. What specific information about the merchant account will my client need to get from his bank to link it up to an online payment gateway that we will be using for the store? -----edits below -"my merchant account" changed to "the merchant account" -It is noted that my client will need to get a "high-risk" merchant account separate from his existing physical stores merchant account. -Though the question is essentially answered, for clarification: We plan to minimize our PCI compliance needs by utilizing something like Braintree's Transparent Redirect or the CRESecure iForm. So the gateway we would need to give the merchant account info to would be either of those two. Though, the CRESecure method would have yet one more step added into the mix since they would forward data to another payment provider. It is now assumed that the best place to field this question is to the support team at Braintree or CRESecure.

• Connecting a LAN to an OpenVPN server via a windows 7 client gateway

  - by user705142

  I've got OpenVPN set up between my windows 7 client and linux server. The goal is that I'll get secure access to a webapp running on the server from any computer on the client LAN. I'm using ccd to assign static ip addresses to each client connection, with key authentication. It's working on my client machine (10.83.41.9), and when you go to the gateway IP address (10.83.41.1), it loads up the webapp. Now I really need the other computers on the client LAN to be able to connect to the webapp as well, via the windows machine. The client has a static IP address of 192.168.2.100 on the LAN, and I've enabled IP forwarding in windows (confirmed by ipconfig /all). In my router I've forwarded 10.83.41.1 / 255.255.255.255 to 192.168.2.100. In server.conf I have.. route 192.168.2.0 255.255.255.0 And in the office ccd.. ifconfig-push 10.83.41.9 10.83.41.10 iroute 192.168.2.0 255.255.255.0 The client log is as follows: Thu Mar 15 20:19:56 2012 OpenVPN 2.2.2 Win32-MSVC++ [SSL] [LZO2] [PKCS11] built on Dec 15 2011 Thu Mar 15 20:19:56 2012 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Thu Mar 15 20:19:56 2012 Control Channel Authentication: using 'ta.key' as a OpenVPN static key file Thu Mar 15 20:19:56 2012 Outgoing Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Incoming Control Channel Authentication: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 LZO compression initialized Thu Mar 15 20:19:56 2012 Control Channel MTU parms [ L:1558 D:166 EF:66 EB:0 ET:0 EL:0 ] Thu Mar 15 20:19:56 2012 Socket Buffers: R=[8192->8192] S=[64512->64512] Thu Mar 15 20:19:56 2012 Data Channel MTU parms [ L:1558 D:1450 EF:58 EB:135 ET:0 EL:0 AF:3/1 ] Thu Mar 15 20:19:56 2012 Local Options hash (VER=V4): '9e7066d2' Thu Mar 15 20:19:56 2012 Expected Remote Options hash (VER=V4): '162b04de' Thu Mar 15 20:19:56 2012 UDPv4 link local: [undef] Thu Mar 15 20:19:56 2012 UDPv4 link remote: 111.65.224.202:1194 Thu Mar 15 20:19:56 2012 TLS: Initial packet from 111.65.224.202:1194, sid=ceb04c22 8cc6d151 Thu Mar 15 20:19:56 2012 VERIFY OK: depth=1, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 VERIFY OK: nsCertType=SERVER Thu Mar 15 20:19:56 2012 VERIFY OK: depth=0, /C=NZ/O=XXX./CN=XXX Thu Mar 15 20:19:56 2012 Replay-window backtrack occurred [1] Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Cipher 'AES-256-CBC' initialized with 256 bit key Thu Mar 15 20:19:56 2012 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Thu Mar 15 20:19:56 2012 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 1024 bit RSA Thu Mar 15 20:19:56 2012 [server] Peer Connection Initiated with 111.65.224.202:1194 Thu Mar 15 20:19:58 2012 SENT CONTROL [server]: 'PUSH_REQUEST' (status=1) Thu Mar 15 20:19:59 2012 PUSH: Received control message: 'PUSH_REPLY,route 10.83.41.1,topology net30,ping 10,ping-restart 120,ifconfig 10.83.41.9 10.83.41.10' Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: timers and/or timeouts modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: --ifconfig/up options modified Thu Mar 15 20:19:59 2012 OPTIONS IMPORT: route options modified Thu Mar 15 20:19:59 2012 ROUTE default_gateway=192.168.2.1 Thu Mar 15 20:19:59 2012 TAP-WIN32 device [OpenVPN] opened: \\.\Global\{B32D85C9-1942-42E2-80BA-7E0B5BB5185F}.tap Thu Mar 15 20:19:59 2012 TAP-Win32 Driver Version 9.9 Thu Mar 15 20:19:59 2012 TAP-Win32 MTU=1500 Thu Mar 15 20:19:59 2012 Notified TAP-Win32 driver to set a DHCP IP/netmask of 10.83.41.9/255.255.255.252 on interface {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} [DHCP-serv: 10.83.41.10, lease-time: 31536000] Thu Mar 15 20:19:59 2012 Successful ARP Flush on interface [45] {B32D85C9-1942-42E2-80BA-7E0B5BB5185F} Thu Mar 15 20:20:04 2012 TEST ROUTES: 1/1 succeeded len=1 ret=1 a=0 u/d=up Thu Mar 15 20:20:04 2012 C:\WINDOWS\system32\route.exe ADD 10.83.41.1 MASK 255.255.255.255 10.83.41.10 Thu Mar 15 20:20:04 2012 ROUTE: CreateIpForwardEntry succeeded with dwForwardMetric1=30 and dwForwardType=4 Thu Mar 15 20:20:04 2012 Route addition via IPAPI succeeded [adaptive] Thu Mar 15 20:20:04 2012 Initialization Sequence Completed From the other machines I can ping 192.169.2.100, but not 10.83.41.1.

Is there something I'm missing, or anything I should need to know?

• how to fix gateway timeout error in php???

  - by developer

  Iam having a php file that sends text messages on mobile to all the users that i have in my database's particular table. Now the entries are like 2000 or so in number and this number will keep on increasing. On my page there is a small form that selects a list of the users to whom message is to be sent from a drop down and then user writes the text to be sent in a textarea and then on clicking the submit button php script stars sending the messages to mobile numbers. Now while trying to send messages my browser has shown gateway timeout error but the script kept on running and messages are sent to the mobiles but not once but 6 times. I checked my script my query and all the code is correct.This all happened coz of that gateway timeout. Now does this gateway timeout kepts the script running again and again till the browser is not closed?? is this was the reason that a single message was sent 6 times to mobile numbers?? I mean how can i escape my file from getting this gateway error so that one message is sent only one time to a number??

• SMS Gateway Suggestions Needed

  - by SidC

  Hi All, Our website is written using PHP and is powered by a hosted Linux web server. We want to allow our users to receive SMS messages when they've received intranet-site messages from fellow users - SMS Notification. What is required to implement this functionality? Are there open source (free?) server applications that address this? Do we need to contract with wireless carriers to send messages to their networks? What, if any fees, must be paid to them? Thanks, Sid

• Fully secured gateway web sites

  - by SeaShore

  Hello, Are there any web sites that serve as gateways for fully encrypted communication? I mean sites with which I can open a secured session, and then to exchange through them with other sites in a secure way both URLs and content? Thanks in advance. UPDATE Sorry for not being clear. I was wondering if there was a way to access any site over the Internet (http or https) without letting any Intranet-proxy read the requested URL or the received content. My question is whether such a site exists, e.g.: I am connected to that site via https, I send it a URL in a secured way, the site gets the content from the target site (possibly in a non-secured way) and returns to me the requested content in a secured way.

  i have tp-link wireless router 192.168.10.188, i was can make it function as DHCP provider(range 192.168.10.100 to 192.168.10.109). the only thing that i cannot make it work as intended, is for it to provide different gateway (192.168.10.1), the computers that obtain IP from that router properly get everything(dynamic IP and dns IP), but there is no function on that router to provide different gateway, the computers always get the router's address(192.168.10.188) as gateway. is there a router that can provide different gateway other than its own address? or the question should be, is the dhcp of a router can provide different gateway other than its own address? note: i cannot make the wireless router address as 192.168.10.1, we have main router(non-wireless, address is 192.168.10.1) that is connected directly to internet

• How to get past black screen with mouse icon while installing on Gateway MX6920?

  - by tom kruse

  I have an old Gateway MX6920 laptop that got a virus on its hard drive so I put in a new one from another laptop. When i turn it on it tries to load Windows but fails so I'm going to try to put Ubuntu on it (because I heard it's a good OS). I downloaded the 32-bit desktop version of Ubuntu and burned it to a CD. I put the CD in the computer, went to the boot menu, and selected CD-ROM. The computer tries to boot but stops at a black screen with a mouse icon sitting in the middle of the display. I have no idea what's going on, so please help.

• Discovering the default gateway without DHCP

  - by JavaRocky

  A crazy question, but is there anyway to discover the default gateway without DHCP? This would be for a device on a network which does not use DHCP which does not have an IP address as yet. I was thinking if I could discover the default gateway, then i could try to guess an unused ip address then broadcast on the network to see if it's being used. I may be asking for trouble i understand. E.g. if there is already a computer which has a static IP and is shutdown.

• Android as SIP to GSM gateway

  - by user346034

  Soon I could use a SIP to GSM gateway, because I'll need to make phone calls from Germany to a mobile phone in Czech Republik. Hence, I thought about implementing one. Now, the questions are: Does such a solution already exist (for a reasonable price)? Is it possible to redirect a (voice) stream to a GSM connection with the available Android APIs (SDK or NDK)? Ideas, suggestions, comments are highly welcome.

• Unlimited SMS API/Gateway (Sending and Receiving)

  - by Naif

  I am creating a chat application which requires that users be able to send and receive sms messages through a web interface. It would be somewhat similar to the text messaging service available in yahoo mail or in aol instant messenger. The situation is this: Given the high quantity of messages that would be sent and received, paying on a per message basis is not economically feasible. How is it that sites such as yahoo, aim, and twitter can send and receive unlimited sms messages? Essentially, I am looking for a way to send and receive unlimited sms from my computer. Below is a list of some approaches I've come up with but have run into problems with as well. If just one of the approaches can be utilized effectively, then I am fine. As a note on the nature of my application: I will only be sending messages to users that explicitly sign up for the service and permit the receiving of messages. They can unsubscribe at any time. This is to prevent spam. I am aware of software such as Kannel which allows one to connect to a providers smsc gateway. However, this adds the risk of not being approved by the provider which would be unacceptable. Is there any way to significantly mitigate this risk? Utilizing a gateway provider eliminates this risk, but adds the issue of per message pricing. I am also aware of email to sms. However, I have done some testing with that and it appears that this method results in many messages being undelivered or delivered VERY late. If it weren't for that, this approach would have been ideal. Is there any way to negotiate with carriers to remove me from their filters (considering the nature of my service as stated before)? I could use a gsm modem, but even with an "unilimited" plan on a sim card, there are still limits (around 100,000 messages or so). Furthermore, from my understanding, gsm modems are capable of only sending out around a dozen messages per minute. I need to be able to send out as much as several hundred messages per second. During the first 2 months, around 10 messages per second would suffice. There are ways to send out ads with messages to cover the per message costs. However, this is a deal-breaker since it has a high chance of tarnishing the quality of service. Furthermore, I know it is possible to do it without such ads since yahoo, aim, and twitter do not send ads with their messages.

• How do I configure a secondary gateway in RHEL5?

  - by Brett Ryan

  Greetings, we have been experiencing a random timeout issue with VPN users connecting to one of our servers which is causing a problem. My network administrator has instructed me to configure a secondary gateway to include the VPN connection. My current connection resides as follows, 10.1.9.1 is the internal gateway to the internet, I'd like to add 10.1.1.20 as the VPN gateway. # Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet DEVICE=eth0 BOOTPROTO=none BROADCAST=10.1.255.255 IPADDR=10.1.1.22 IPV6_AUTOCONF=yes NETMASK=255.255.0.0 NETWORK=10.1.0.0 ONBOOT=yes GATEWAY=10.1.9.1 TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes

• SMS Gateway Devices

  - by u07ch

  Can anyone recommend a good SMS Gateway device that sends and receives messages and has a reasonable API. We are looking for a hardware device that a Sim Card and works with Windows / .Net. I am working with about 50 different countries (Right now 50 will only become more in the future) and dealing with that many SMS suppliers and their various methods for billing and sending / responding to messages is proving unmanageable. It may be much easier to have a single method and call it by country. We do bulk send messages but from the logs this is at most 500 messages at a time (though it could be up-to about 1500 at a time) - mostly its small numbers far less than 500 messages. Ideally would like to get message delivery data and error handling type messages back from the device. I am not interested in a hosted solution unless it has the ability to receive a message to a local number in EVERY country.

• Building a complete online payment gateway like Paypal

  - by John Stewart

  So this question isn't about integrating an existing payment gateway into my site. This is more of a architectural question. I want to build a system similar to Paypal. Now I understand that Paypal offers a lot of features under the roof and I can't implement all of them at once. I want to implement the core functionality of Paypal and other such services. So my question is (rather discussion is) around how would one go about building such a system. Some points to discuss: Handle payments through existing banks. I am guessing that I would need access to local bank protocols to get this. Allow users to securely store and process their payments How does Paypal handle the transactions? Thoughts?

• Payment Gateway Question

  - by Sphynx

  Hi, My question is not exactly about coding, and I'm not sure if I can ask it here. Nevertheless, it's somewhat related to the payment integration process. I'm going to establish a service, and deliver it through a website. When you accept payments through PayPal, they display your actual name to every client, and I'm not that comfortable with such lack of privacy. Is there any way around that? Perhaps an alternative payment gateway that doesn't display your personal info to everyone? Any suggestions welcome! Thanks
