  • Do all web caches understand the "Cache-Control" HTTP header?

    - by chris_l
    I'd like to avoid the "Expires" header, and use "Cache-Control" only - or maybe the other way around. The headers will account for a significant percentage of my traffic, so I'd prefer not to "use both". AFAIK, the "Cache-Control" header was standardized in HTTP 1.1, but are there still web caches/proxies in use, which don't understand it? Note: This could help answering a part of my stackoverflow (bounty) question

  • cluster live postgres 8.3 server

    - by bobinabottle
    Our web application is getting more and more traffic, which is making our poor pg8.3 database server have a little trouble keeping up. I've had a look into using pgpool II for clustering the db to relieve a little strain, and I was wondering how this should be done to minimise downtime considering I would be clustering a live database. Has anyone had experience with this or know of any guides to follow? Cheers :)

  • Setup a vpn server with a static IP with NAT and port forwarding

    - by Lorenzo Pistone
    I have a Debian VPS with an assigned static IP. I want to setup a virtual interface (with an ip like 192.168..) on my laptop (Ubuntu, dynamic IP) linked to the remote VPS, so that if I bind sockets to it the traffic is tunneled to the VPS and sent to the Internet from there. Port forwarding must be available. This looks like a job for a VPN software, but I'm clueless about the pieces of software needed. Any advice?

  • Can Azure host ColdFusion?

    - by mbursill
    A friend has a site developed in ColdFusion with MySQL and is looking for better cost-effective hosting as the traffic scales up rapidly. Azure comes to mind. I haven't used Azure myself, however, I believe it is possible to setup and interact with the web-server via RDP into a hosted Virtual Machine? I am curious if ColdFusion can be installed in the hosted Azure VM. Also, would the site have to be tweaked to run on Azure SQL, or could it continue to use MySQL? Thanks.

  • How do I configure dual WAN links for failover on a Cisco 891?

    - by Donjo
    I have a Cisco 891 that is going to be connected to 2 WAN links, a DSL connection and a cable connection. I'm not so concerned with load balancing between them because the DSL connection speed is a drop in the bucket when compared to the cable speed though it would be nice if it worked that way. I mainly just want to force all traffic through the cable WAN link unless it goes down. I'm not really sure what feature set I should be researching.

  • Are there any routers supporting client-side VPN?

    - by Andreas Hagen
    What I'm asking for is basically what the title says. I need a router that can forward all the data-traffic it receives through a VPN tunnel. Have Google'd a little but I can't seam to find a topic which the links to potential products still are active. The parameters to the specific VPN it is going to be used with is as follows: Sorry it is in Norwegian, but you should be able recognize the relevant parameters like encryption and such.

  • Keep source IP after NAT

    - by John Miller
    Until today I used a cheapy router so I can share my internet connection and keep a webserver online too, while using NAT. Users IP ($_SERVER['REMOTE_ADDR']) was fine, I was seeing class A IPs of users. But as traffic grown up everyday, I had to install a Linux Server (Debian) to share my Internet Connection, because my old router couldn't keep the traffic anymore. I shared the internet via IPTABLES using NAT, but now, after forwarding port 80 to my webserver, now instead of seeing real users IP, I see my Gateway IP (Linux Internal IP) as any user IP Address. How to solve this issue? I edited my post, so I can paste the rules I'm currently using. #!/bin/sh #I made a script to set the rules #I flush everything here. iptables --flush iptables --table nat --flush iptables --delete-chain iptables --table nat --delete-chain iptables -F iptables -X # I drop everything as a general rule, but this is disabled under testing # iptables -P INPUT DROP # iptables -P OUTPUT DROP # these are the loopback rules iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT # here I set the SSH port rules, so I can connect to my server iptables -A INPUT -p tcp --sport 513:65535 --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -p tcp --sport 22 --dport 513:65535 -m state --state ESTABLISHED -j ACCEPT # These are the forwards for 80 port iptables -t nat -A PREROUTING -p tcp -s 0/0 -d xx.xx.xx.xx --dport 80 -j DNAT --to 192.168.42.3:80 iptables -t nat -A POSTROUTING -o eth0 -d xx.xx.xx.xx -j SNAT --to-source 192.168.42.3 iptables -A FORWARD -p tcp -s 192.168.42.3 --sport 80 -j ACCEPT # These are the forwards for bind/dns iptables -t nat -A PREROUTING -p udp -s 0/0 -d xx.xx.xx.xx --dport 53 -j DNAT --to 192.168.42.3:53 iptables -t nat -A POSTROUTING -o eth0 -d xx.xx.xx.xx -j SNAT --to-source 192.168.42.3 iptables -A FORWARD -p udp -s 192.168.42.3 --sport 53 -j ACCEPT # And these are the rules so I can share my internet connection iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A FORWARD -i eth0:1 -j ACCEPT If I delete the MASQUERADE part, I see my real IP while echoing it with PHP, but I don't have internet. How to do, to have internet and see my real IP while ports are forwarded too? ** xx.xx.xx.xx - is my public IP. I hid it for security reasons.

  • nginx rule to capture header and append value as query string

    - by John Schulze
    I have an interesting problem I need to solve in nginx: one of the sites I'm building receives inbound traffic on port 80 (and only port 80) which may have a certain header set in the request. If this header is present I need to capture the value of it and append that as a querystring parameter before doing a temporary redirect (rewrite) to a different (secure) server, while passing the paramater and any other querystring params along. This should be very doable, but how!? Many thanks, JS

  • Unable to telnet out on port 25 on windows server 2008

    - by NickGPS
    Hi All, I just setup a Windows 2008 R2 server and am trying to get a basic mail server up and running so that I can send emails from my applications. I setup a virtual SMTP server in IIS6 and tried doing a local telnet to port 25, which seemed to work fine. There were no errors during this stage and I can see the mail message appear in the Queue folder. The problem is that mail never leaves the Queue folder. I then tried to telnet to a remote mail server on port 25 but couldn't connect:- telnet 209.85.227.27 25 Could not open connection to the host, on port 25: Connection failed) I checked my firewall and there is a default setting to allow all outgoing TCP traffic with no restriction. I even setup a specific rule for outgoing port 25 traffic but to no avail. I then ran a SmtpDiag.exe command .\SmtpDiag.exe [email protected] [email protected] and received the following output Searching for Exchange external DNS settings. Computer name is WIN-SERVERNAME. Failed to connect to the domain controller. Error: 8007054b Checking SOA for gmail.com. Checking external DNS servers. Checking internal DNS servers. SOA serial number match: Passed. Checking local domain records. Checking MX records using TCP: gmail.com. Checking MX records using UDP: gmail.com. Both TCP and UDP queries succeeded. Local DNS test passed. Checking remote domain records. Checking MX records using TCP: gmail.com. Checking MX records using UDP: gmail.com. Both TCP and UDP queries succeeded. Remote DNS test passed. Checking MX servers listed for [email protected]. Connecting to gmail-smtp-in.l.google.com [209.85.227.27] on port 25. Connecting to the server failed. Error: 10060 Failed to submit mail to gmail-smtp-in.l.google.com. Is there any other diagnostics I can do to figure out if it's my firewall or something else? I have removed antivirus to make sure that it wasn't causing the problem. Any ideas would be much appreciated.

  • .NET 4 Shared Hosting

    - by Unknown
    Are there any companies that offer shared .NET 4 hosting? I know its still in beta, but from about hours worth of searching, I only found that ASPHostCentral.com offers it. MaximumASP.com and DiscountASP.net currently only offer sandboxing plans. I don't want to get a dedicated server or VPS since my website has low traffic.

  • Routing all data through an VPN tunnel with ppp

    - by Oliver
    I'm trying to create a VPN tunnel that forwards all data from the local machine to the VPN server. I'm using ppp-2.4.5 for this with the following configuration: pty "pptp <VPNServer> --nolaunchpppd" name <my login name> remotename PPTP usepeerdns require-mppe-128 file /etc/ppp/options.pptp persist maxfail 0 holdoff 5 I have a script in if-up.d with the following content: route del default eth0 route add default dev ppp0 Before starting the VPN tunnel my routing looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 2 0 0 eth0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 After starting the tunnel (via pon) it looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 12.34.56.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 Now the problem is, that the VPN tunnel seems to be looped into itself.

Can someone please help me to fix the routing table, so that the traffic from ppp0 is not send again through ppp0 but instead goes to the remote server?

  • SSH tunneling hangs with many connections

    - by middleofdreams
    I am forced to use SSH tunneling to access many servers (over 100) via one gateway server. To keep connection alive I am using autossh. Everything works pretty well until there is high traffic (people are connecting to most of the servers at once). then ssh process reaches 12% of cpu (which is configured maximum for separate process) and no connection is working anymore - i have to restart autossh script. What could be the possible reason for that?

  • How to make `rm` faster on ext3/linux?

    - by depesz
    I have ext3 filesystem mounted with default options. On it I have some ~ 100GB files. Removal of any of such files takes long time (8 minutes) and causes a lot of io traffic, which increases load on server. Is there any way to make the rm not as disruptive?

  • Pros and Cons of Creating an Internal Cerificate Authority

    - by Chad
    What are the pros and cons of spinning up an internal certificate authority (primarily Windows 2003 CA)? We have the need to encypt server-server traffic on a project that has 20+ certificates. We could buy certs from Verisign, but I was thinking that an internal CA might be a better long term solution. So I was looking to the community to provide a pros/cons list of what we might gain (or lose) by hosting our own CA? Thanks in advance for the help.

  • How Windows Server routes PTP v2 unicast messages?

    - by Bobb
    If my server is placed in PTP v2 enabled network which has grand master clock. And the switch is PTP aware. The server is W2008R2 (soon to be W2012). I also have PTP v2 software client. How does the master clock messages are getting on with Windows Server? Does it need special PTP-aware NIC or it will be treated as normal networking traffic and the software receives it through regular NIC no problem?

  • How to configure an isa server to allow a OPENvpn client to connect to an outside server?

    - by rmarimon
    I'm trying to configure an ISA server (not really my area of expertise) to allow an openvpn client (in the lan) access to an outside openvpn server (in the wan). The openvpn configuration I'm using has worked everywhere. In fact if I take the client outside the lan where the isa server is located, it works perfectly. Inside the isa server lan nothing. The question is what configuration do I need to put on the isa server to allow openvpn traffic to go through?

  • List Squid's internal ip:port to external ip:port mapping table

    - by joshperry
    I'm assuming that squid keeps a list of internal ip:port that a request is made on and the matching external ip:port that the request is fulfilled with. In the case of a long transfer, such as a file download, it would be nice to be able to see which internal ip:port is downloading the file. I am able to see the traffic and get the external ip:port that squid is using easily with tcpdump or iptraf but I can't find a way to map this back to an internal ip:port.
