  • Configuration Manager sub site codes

    - by NA Slacker
    I have two sub-sites set up in configuration manager. When the SCCM agent installs on the client machines within the boundaries of those sub sites they are assigned the site code of the Primary site, not the sub site code. As a result their management server remains the main server not the sub site server. I am setting up thes sub sites on cross WAN locations to cut down on traffic. What could be preventing the clients from getting associated with the proper sub site code.

  • PPTP VPN Not Working - Peer failed CHAP authentication, PTY read or GRE write failed

    - by armani
    Brand-new install of CentOS 6.3. Followed this guide: http://www.members.optushome.com.au/~wskwok/poptop_ads_howto_1.htm And I got PPTPd running [v1.3.4]. I got the VPN to authenticate users against our Active Directory using winbind, smb, etc. All my tests to see if I'm still authenticated to the AD server pass ["kinit -V [email protected]", "smbclient", "wbinfo -t"]. VPN users were able to connect for like . . . an hour. I tried connecting from my Android phone using domain credentials and saw that I got an IP allocated for internal VPN users [which I've since changed the range, but even setting it back to the initial doesn't work]. Ever since then, no matter what settings I try, I pretty much consistently get this in my /var/log/messages [and the VPN client fails]: [root@vpn2 ~]# tail /var/log/messages Aug 31 15:57:22 vpn2 pppd[18386]: pppd 2.4.5 started by root, uid 0 Aug 31 15:57:22 vpn2 pppd[18386]: Using interface ppp0 Aug 31 15:57:22 vpn2 pppd[18386]: Connect: ppp0 <--> /dev/pts/1 Aug 31 15:57:22 vpn2 pptpd[18385]: GRE: Bad checksum from pppd.

We're using a Juniper SSG-5 Gateway, and I've assigned a WAN IP to the VPN box itself, zoned into the DMZ zone. Then, I have full "Any IP / Any Protocol" open traffic rules between DMZ<--Untrust Zone, and DMZ<--Trust Zone. I'll limit this later to just the authenticating traffic it needs, but for now I think we can rule out the firewall blocking anything. Here's my /etc/pptpd.conf [omitting comments]: option /etc/ppp/options.pptpd logwtmp localip [EXTERNAL_IP_ADDRESS] remoteip [ANOTHER_EXTERNAL_IP_ADDRESS, AND HAVE TRIED AN ARBITRARY GROUP LIKE 5.5.0.0-100] Here's my /etc/ppp/options.pptpd.conf [omitting comments]: name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 192.168.200.42 # This is our internal domain controller ms-wins 192.168.200.42 proxyarp lock nobsdcomp novj novjccomp nologfd auth nodefaultroute plugin winbind.so ntlm_auth-helper "/usr/bin/ntlm_auth --helper-protocol=ntlm-server-1" Any help is GREATLY appreciated. I can give you any more info you need to know, and it's a new test server, so I can perform any tests/reboots required to get it up and going. Thanks a ton.

  • Multi-site email relay based on email address (in AD?)

    - by MarkRobinson
    We have a multi site setup currently based around Exchange 2003, but we are getting a lot of traffic over the vpn as only one server has an internet facing IP. Is there such a product that could sit on a hosted rack somewhere that would look at an incoming email and from information in AD determine which mail server to relay the message to?

  • HAProxy redirect HTTPS to HTTP

    - by tarnfeld
    I'm using HAProxy as a load balancer and i'd like to redirect any traffic that comes in on 443 (HTTPS) to 80 (HTTP). My site doesn't support HTTPS at all and i'd rather just redirect users than cause any SSL warnings in browsers. All I can find is using the redirect location <to> syntax, but as far as I can tell that requires me to hard code the hostname. The load balancer receives connections for various hostnames so would like to keep it relative.

  • 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

  • Accessing local resources over wifi with a BES-connected Blackberry

    - by bshacklett
    I'm trying to get to a local web site on my LAN at 192.168.1.10 with my Blackberry, but I'm getting a message saying the server did not respond. I know that some, if not all, internet traffic on a BES-connected blackberry goes through the BES. This is clear because I can access internal resources on my employers network via the mobile network. Is there any way for me to specify that the device should attempt to route directly over wifi before it tries to connect via the BES server at work?

  • 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 :)

  • Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

    - by Alexander
    I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

  • 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.

  • "The connection to the server was reset while the page was loading"

    - by andygeers
    I've just taken over managing the network for a small charity, and am finding internet access very flaky - we keep getting "The connection to the server was reset while the page was loading." errors (HTTP Error 12031 according to the Windows network diagnostic tool). It doesn't seem to be anything to do with our ISP since it also affects internal traffic (even requests to an Apache instance on my localhost!) Adjusting the MTU setting in the Windows XP registry sometimes seems to help for a few minutes after rebooting, but the problem always returns.

  • Port forwarding using a BT Home Hub 2.0 (Supplied to new BT Infinity Customers in the UK)

    - by Jasarien
    I don't usually have trouble with port forwarding, I've been able to do it successfully on a number of different routers, including Linksys, Belkin, Netgear and Apple (Time Capsule / Airport Extreme). So I'm quite confused here. I had been using my Apple Time Capsule as my router for a few years now, with several port mappings all working fine. But it died recently, so I've had to resort to using the BT Home Hub 2.0 that was supplied with my BT Infinity broadband subscription. The forwarding interface for the Home Hub is simplified for the most part, allowing you to select an application or game and assign it to a particular computer on the network which you choose from a list that the Home Hub has 'discovered'. My Mac Pro has a manually assigned static IP 192.168.1.4 and my router is static at 192.168.1. I have chosen SSH from the list of applications and assigned it to my Mac Pro (the only computer in the list currently). The Home Hub also has a feature to keep a DNS service updated, and I have set it to keep my external IP address updated on my hostname. This is how I had it setup in the past with other routers and not had trouble before. I am able to ping my hostname (and external IP) from outside the network and get a response. But when I try to connect using SSH, the connection times out. The Home Hub also has "Firewall settings". The currently selected setting is: Default: Allow all outgoing connections and block all incoming traffic. Games and application sharing is allowed. But I've tried changing it to: Disabled: All traffic is allowed to pass through your BT Home Hub to your devices. Note: you’ll still need to use the games and application sharing feature to make sure that certain applications work properly. And the connection still times out... So frustrating. The OS X firewall on my Mac is disabled, so I don't think that's in the way. I have tried setting the port forwarding manually, instead of relying on the preset "SSH" option (incase it's not using the port I expect). So I set up my own "application" (as the Home Hub calls it) and forwarded external port 22 TCP to internal port 22 TCP to 192.168.1.4 - but that just gives the same result - unable to connect. Next, with the router's firewall disabled and OS X's firewall disabled, I ran the Shields Up test (https://www.grc.com/x/ne.dll?bh0bkyd2) and the result was that all my service ports (0 - 1055) are in 'Stealth' mode. I.e. nothing even exists at my IP as far as any outsider is concerned... Strange. The only thing that seems to work is setting my Mac Pro as the DMZ - which I don't want to do for obvious reasons. Any help with this would be extremely appreciated, thanks.

  • Determine who is opening a .PST file from a network drive on the local network?

    - by hypoxide
    Our system admin has been struggling with the issue of our network getting completely locked up when users open PST files from network drives. Apparently Microsoft is aware of this problem but there is no fix for it. The entire local network is unable to use Outlook while this file is being opened (which may take hours). Is there a way to determine which user is opening the file instead of forcing everyone in the office to close outlook (like a traffic monitor or something)?

  • 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?

  • Transient network dropout for Xen DomU's

    - by Stephen C
    We've got a CentOS server running a cluster of virtuals. Occasionally the cluster's internal network drops out for a minute or so ... and then comes back. The problem is somehow related to the actual network traffic, but it is not a simple load issue. (The system is generally lightly loaded, and the problem occurs irrespective of actual load.) The setup: CentOS 5.6 on Dom0, various CentOS on the DomU's Hardware - a Dell R710 with a BroadCom NextXpress 2 NIC (sigh) using the latest drivers for the NIC from BroadCom Xen configured to use network-bridge and vif-bridge Some iptable tweaks to route an unrelated port to one of the virtuals. The system has one externally visible IP address, and Dom0 runs an Apache httpd configured with a number of virtual hosts each of which reverse proxies to web servers running on the virtuals. (The virtuals have to be NAT'ed, primarily because we don't have enough allocated public IP addresses.) The symptoms: Works fine most of the time. When someone tries to UPLOAD a large file to one virtuals, the internal network drops out ... for all virtuals: The Dom0 httpd sees a network timeout talking to the backend server on the virtual and reports a 502. A previously established ssh connection from Dom0 to any of the DomU's freezes. Our monitoring shows ping failures for traffic between virtuals. The Xen consoles to the DomU's do not freeze. No log messages in any log files that I can see, on either Dom0 or the DomU's ... apart from the Dom0 httpd logs. After a minute or so, the problem clears by itself. This is 100% reproducible. What we've tried: Downloading, building and installing the latest BNX2 driver on Dom0 Turning off MSI on the NIC - adding "options bnx2 disable_msi=1" to /etc/modprobe.conf Turning off tcp segmentation offload - "ethtool -K eth0 tso off". Sacrificing a black rooster at midnight. I've exhausted all my options apart from switching to KVM ... or slaughtering more roosters. Any suggestions?

  • 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.

  • 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.

  • 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.

  • .NET 4 Shared Hosting

    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.
