• A switch and router between the printer and PC that want to print but cannot

  - by Robert Memo

  IP 192.168.1.5 has a wireless connection to a Linksys router (192.168.1.1) which then is connected to a switch. The switch is connected to a server (192.168.0.2). My printer has IP address of 192.168.0.8. Internet connection is fine on 192.168.1.5. Problem 1: IP 192.168.1.5 can not print using printer 192.168.0.8. Problem 2: IP 192.168.1.2 can not access a shared folder on the the server. The reason for connecting this way is that, the server does not release wireless signal. In order to get wireless signal the Router is connected to the switch. The server is a computer server that only has one outgoing LAN port. Plus, due to inconvinience physical locations, I do not have option to change the physical locations and the way it is connected already. I just want the labtops that only have wireless connection to communicate with the printer and the server. I have tried to change the router IP address to 192.168.0.x like the server and printer. It caused problem for the laptop. The router no longer release internet signals. The router does have IP address from the server 192.168.0.5.

  - by Sebastian

  Hi, I have a SBS2003 runing Exchange Server 2003 SP2. My OWA has a godaddy certificate valid for 3 years to come installed. HTTPS works fine for OWA. The certificate has also been copied into the Nokia E95 I am trying to syncronize my Nokia E75 via Mail for Exchange to my mail account on the Exchange server. These are the steps i use: Menu Email New Start Select Internet Gateway Than i enter the details: [email protected] I select company email Mail for Exchange In the domain menu i enter : mydomain In the username/password menu i enter : myusername/mypassword In the server menu i enter : mail.mydomain.com (where the DNS resolves into the server's IP address) In the secure access i select : Internet / Secure / 443 NOTE : port 443 has been opened on my SBOX and forwarded to the exchange server. On IIS default website properties directory security secure communications edit the "Require Secure Channel SSL" is enabled.

• Cannot install windows. Compaq Presario CQ62

  - by Matthew

  I bought a used Compaq Presario CQ62 for cheap, and went to install windows on it. I formatted the partition and went to install when I got this error.... Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error code: 0x80070017 I have used this disk before with no problems, but internet searching suggested I burn one at 2x speed because that helps for some reason... I'm burning one now, but my question is, why would I get this error, OTHER than the disc being bad? I'm pretty certain this one isn't as I have used it before... (ok so the slowly burned cd (using imgburn) didn't work either so it's DEFINITELY not the disc) Thanks in advanced for any answers Also I took one stick of ram out because internet searching also suggested that, but it didn't make a difference. Also I ran memory and hard drive checks and they passed fine. Also I reset the motherboard options to default What could it be!? Help I'm completely stumped...

• Linux as a gateway (no NAT)

  - by Hugo

  I'm trying to configure a linux server as a gateway/router, but I can't get it to work, and all information I've managed to find is NAT-related. I have a public IP block for the gateway and devices behind it, so I want the gateway to simply route packets to the internet - again: no NATing! I've managed to get the gateway to access the internet successfully (that was just a matter of configuring the IP and GW), and the computers behind it can communicate with it. [EDIT: more info] This is actually an IPv6 block (2800:40:403::0/48) (but I've found that most utilities and instructions can be easily adapted from IPv4 to IPv6 with little hastle). The server has too ports: wan: 2800:40:403::1/48 lan: 2800:40:403::3/48 One of the computers behind it is connected to it via a switch; 2800:40:403::7/48 The wan interface on the server can ping6 www.google.com without issues. The lan interface on the server and the client can mutually ping each other without issues (as well as SSH, etc). I've tried setting the server as a default gateway for the client, with no luck: client # route -A inet6 add default gw 2800:40:403::3 dev eth1 server # cat /proc/sys/net/ipv6/conf/all/forwarding 1 I don't want any filtering/firewalling/etc, just plain routing. Thanks.

• I just got a virus 6 mins ago, how? Situation.

  - by acidzombie24

  -Edit- for the people who say it isn't a virus. Norton does detect it as a virus, an icon was placed on my system tray and rkpg.exe is in my C: which was placed 6 min ago around the time my computer rebooted on its own causing me to lose data :@. Situation I on Windows XP, behind a Linksys router, I don't have DMZ on so nothing should be connecting to me. I had Firefox, MSN and Visual Studio opened. With C# I programmed a quick application to scan some pages with Internet Explorer. The site it was scanning was deviantART (which is pretty trustworthy), I doubt any banners there would hold a virus. I went to a suspicious site called freetxt.com but that was on Firefox and it didn't load the site. With an extra check I ping it and got this message "Ping request could not find host freetxt.com." The virus seems to be called braviax. Right now it brought up a message saying my computer may be infected? How on earth did it get in? I don't have uTorrent installed or any torrent or p2p applications. Nothing is installed on my computer that I haven't installed before and I know the exact time it installed because I see rkpg.exe on my C drive and my computer restarted on its own around the same time. For the previous 30 minutes actually the previous hour all I did was talk on MSN, not click any links (I went to freetxt on my own) and had that Internet Explorer thing running (which I programmed). How did it get in? I really doubt it came from a banner on deviantART and installed when I loaded the page with the webbrowser-control so something else may have happened? Is there any system defaults I should turn off? I have remote assistance off but even if it was on I shouldn't be infected due to the router not forwarding any ports?

• Connecting to network device behind NAT from local LAN using the external port and IP

  - by lumbric

  I noticed at several different LANs connected to the Internet through a NAT the following phenomena. There is a server in the LAN and there is a port forwarding to reach this server also from outside the LAN through the NAT. E.g. consider a LAN with the address 192.168.0.* and a SSH server at 192.168.0.2 with port 22 and a forwarding from port 2222 at the NAT 192.168.0.1 to 192.168.0.2:22. If the NAT's external IP is 44.33.22.11, one can connect to the SSH server through 44.33.22.11:2222. Surprisingly this works only from outside the LAN. If one tries to connect to 44.33.22.11:2222 from behind the NAT, there is no answer. Of course one could simply use 192.168.0.2:22, but often it is simpler to use the external IP. The typical use case for me is the configuration on a laptop computer. Usually the user uses any arbitrary Internet connection to connect to his home or office server, but sometimes he will use also the LAN to connect to it and it would be annoying to have to different configurations or bookmarks. Why does it fail to connect from inside the LAN? Is there any good work around?

• Curious enigma of a network cable / connection / quality

  - by Foo Bar

  So, the situation is like this: I'm renting an apartment in a large house and I'm sharing internet with the landlord who lives downstairs. The internet is (in my best guess) optical 20/20Mbit. I don't know how it's all wired in his flat (haven't been there / seen it). Anyway, in my flat comes a cable which seems to be connected directly to the optic to ethernet router (and the password is the default one, so I have access, he he). There was a switch connected to that and to wires that go around the flat, and the wiring is terrible. It's even mixing phone and ethernet, and from what I see some cables are even interconnected!? Anyways, this cable that comes to my flat is very short. I can barely connect my computer on it, but if I do, I seem to get decent speed / performance. Not great, but decent. If, however, I connect switch to it (tried 2 different switches and a wifi switch) it's all blinking but I can't even connect to 192.168.1.1 (the router). DHCP fails, ping is losing 80-100% of replies. So I connected this cable directly to the other cable which goes to my work room, with a connector that has two female jacks and no electronics. Now when I connect my computer in my room, again, the performance is decent. When I connect WRT54GL (with tomato, DHCP disabled) to it and I plug a cable in this WRT and to my computer... the performance is gone. Download seems okay on Speedtest, but upload is .2Mbps and it's connecting forever. So what kind cable troll am I having here? Any ideas?

• exchange server 2010 with multiple domains

  - by air

  i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server. Thanks

• Two network adapters in one WindowsXP PC, how to make them work?

  - by Deele

  I have a need to set up network so I can use two ethernet cards inside one Windows (Windows XP SP2) based PC, one for internet connection, second, for internal LAN. How should I configure each NIC, with what IP's, subnet masks and gateways, so I can use inernet on my PC and get in touch with devices on my LAN? I have found that there are some sort of re routing nessesary inside my PC, but how does it work? I have already set up some configuration already, but I can't use it together with PC #1 NIC #1 connected. I need to disconnect, to access NIC WEB interface. Current configuration: Switch #1 and PC #1 NAS #2 are gigabit one's, so I could access NAS with gigabit speed. PC #1 NIC #1 IP XX.XXX.162.106 SN 255.255.255.248 GW XX.XXX.162.105 PC #1 NIC #2 IP 10.0.0.1 SN 255.255.0.0 GW 0.0.0.0 NAS #1 NIC #1 IP 10.0.0.12 SN 255.255.0.0 GW 0.0.0.0 My question is - what exact configuration should I do for every NIC in this LAN, so it would work? Is it possible to achieve internet access for Laptop, that is inside that NIC #2 LAN (should I just set up basic ICS)?

• VPN: Disable class based route addition for Windows XP/Vista

  - by brgsousa

  Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)

• System With Two Network Adapters [closed]

  - by Synetech inc.

  Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

• Windows 7: resizing the 'Save As' window

  - by Mark Miller

  I do not know whether my question is appropriate for this forum. Apologies if it is not. I am running Windows 7 Professional with Service Pack 1 on a Dell Vostro 460 PC. I am downloading journal articles from the internet and saving them as *.pdf files. Somehow I unintentionally clicked a button that resulted in the 'Save as' window filling the entire screen of my computer, except for the toolbar at the very bottom. How can I resize the 'Save as' window so it only fills perhaps somewhere around 25% of the computer screen, or whatever the default size for that window is? I have searched the internet extensively and found one or two threads about this problem, but no specific solutions were posted there. One suggestion was to grab the bottom of the window with the mouse and scroll upward until the window was the desired size. That does not appear to be possible in my case. Another suggestion was to click on the window with the middle mouse button before attempting to resize the window, but that does not appear to help in my case either. Thank you for any help. If I should post this question in a different forum here please let me know, or kindly migrate the question to the appropriate forum. If additional information is necessary before a solution can be attempted, please let me know that as well.

• How to stop my wireless adapter from received dhcp from router (windows)

  - by baobeiii

  Hi, I have a windows 7 computer which is connected via vpn to an OpenVpn server which happens to be in another country. I have all internet traffic being routed from my computer through the vpn to the server. However dns queries are not going through the vpn, but are instead going directly to my isp's dns via a route outside of the vpn tunnel. This is happening because my wireless adapter is configured to obtain DNS server address automatically. The router that stands between my computer and the internet happens to have a DCHP server running on it that is assinging my computer with the DNS addresses of the isp. The issue is, i haven't been able to stop my wireless adapter on my computer from receiving the dns settings from the router. I've tried selecting 'use the following dns server addresses' and then just leaving them blank, but ipconfig /all shows me that this hasn't worked and i'm still getting dns form the router. So is there any way to completely stop my windows wireless adapter from receiving these settings from the router? I have the OpenVpn server pushing to my computer's tun adapter the dns that it should be using. I'd rather solve this in a way that doesn't involve disabling the dhcp server on the router or fiddling with the router. The reason is i'm on a laptop and i want my vpn to not leak dns even when i'm out, for example in wireless hotspots. I know if i could just force the wireless adapter to ignore the router's dhcp server then my dns queries would go through the tunnel to the dns address pushed by the OpenVpn server. Sorry, i know thats long winded, if you have any idea's please do tell me. Thanks and merry xmas.

• iptables (DNAT)

  - by user1126425

  I have a host that acts as a gateway for other hosts. The configuration is such that eth0(192.168.1.3) is connected to internet via a router and eth1(172.16.2.50) is connected to internal network via switch. Given that, this host is also running a service that is bound to eth1 and serves the internal network. I want to extend this service to the outside world as well and was trying to manipulate iptables so that any request that comes to this host via eth0 and is directed to 192.168.1.3:80 is send to 172.16.2.50 and internet users can also make use of the service. Here are my iptable rules for setting up the host as gateway (and these work fine): sudo iptables -t nat -A POSTROUTING -s 172.16.2.0/16 -o eth0 -j MASQUERADE sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth1 -j MASQUERADE sudo iptables -A FORWARD -s 172.16.2.0/16 -o eth0 -j ACCEPT sudo iptables -A FORWARD -d 172.16.2.0/16 -m state --state ESTABLISHED,RELATED -i eth0 -j ACCEPT And these are the rules that I am trying to add to the iptables to achieve my ends: sudo iptables -A INPUT -d 192.168.1.3 -p tcp -dport 80 -i eth0 -j ACCEPT sudo iptables -t nat -A PREROUTING -d 192.168.1.3 -p tcp -dport 80 -j DNAT --to-destination 172.16.2.50:80 sudo iptables -t nat -A PREROUTING -s 172.16.2.50 -p tcp -sport 80 -j SNAT --to-source 192.168.1.3:80 sudo iptables -A FORWARD -d 192.168.1.3 -p tcp -dport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT When I do so, I get error like : "multiple -d flags not allowed" ... Can someone tell me how to resolve this error... and do the entries that I want to add will serve my purpose ? Thanks!

• Is it possible to add a WiFi HotSpot to an already established LAN, keep the two separate, and not modify the primary router?

  - by user12844

  I have a set up where my Cisco ASA is sitting in one facility, providing access to the Internet for two buildings. The two buildings are geographically separated by a Wireless Bridge spanning about 10 miles. All computers and equipment inside the LAN are on the same subnet (its pretty small) and we have WiFi AP's in both locations providing Wired and Wireless access to the LAN. Given all the BYOD (Ipods, and SmartPhones etc...) coming into the office as well as Visiting reps etc... we would like to also provide a non-secure, device independent (the devices cannot see or communicate with each other), and LAN independent (the devices cannot see or use anything on the LAN) HotSpot that anyone could use for their Devices that gives them access to the Internet ONLY without needing a password. I get that this could be possible at the facility with my Cisco if I messed with it and created VLANs etc... but then I would need to get it across my Bridge as well and don't think that would be possible without serious reconfiguration of everything. Would really like some kind of magic drop in solution that can kind of piggy back on my LAN without really needing to do very many if any changes to the current set up.

• Bypass insane corporate security system

  - by user1665154

  I'm searching for a posibility to bypass the "Firewall" for 3-4 days. I've tried everything I know, so I ask here for a answer. We have no admin rights and the OS is Windows Vista There is an HTTP Proxy with NTML Authentication (only way to access the internet) It requires a username and password We use smart cards, in fact I have only a user number and a pin. Port 80 and 443 are open - I have an SSH server at home which is listening on port 443 The problem is that I need this proxy to connect to anything. Internet access only works in IE, Chrome, Firefox when I set the proxy settings to "use system proxy settings", "proxy-autoconfig (proxy.pac)" or when I enter the proxy inside the proxy.pac file. However I can't understand where they take the username and password which the Proxy requires. What I've tried was using cntlm to connect to the proxy with authentication (altought I have no PW and username) and PuTTY to create the SSH tunnel over port 443 whit the SOCKS Proxy which I've created with cntml. I've never found some SSH client which includes a "use system proxy settings" function.

• Intranet machines refuse to talk anymore

  - by ashes999

  I have two machines on the local intranet. They used to be able to talk to each other (ping, share files, etc.). Both are not successfully connected to the internet. The problem machine (lets call it test machine) can't talk to my main machine. The test machine can ping other machines on the intranet (at least one of my coworkers), but not mine. Odd. When I try to ping it from my machine, by machine name, I get Destination host unreachable. Both machines are on the intranet, with the network configured as Work Both machines have Windows Firewall disabled temporarily Both machines can talk to the internet (Google, SO, etc.) Neither machine can ping the other I need help resolving this. What I really want to achieve, is to remote into the test machine from my main machine, like I used to be able to do a few weeks ago. Some notes: Tried arp -a on both machines. I don't see the other machine's IP listed. Both machines have stable IPs; neither seems to have an IP conflict The configuration under ipconfig /all on my main machine mathces my coworker's machine. The test machine can ping his machine, but not my machine. The target machine times out trying to ping the main machine; the main machine gives me Destination host unreachable. I have rebooted both machines (several times) to no avail I have /release and /renewed both machines several times

• Windows 7, network transmit (send) not working

  - by user326287

  My Win 7 works 2 years without problem. But now, I can't transmit (send) big data on LAN/Internet. I can: - Ping anything - Browse Internet, download files at full speed - Send e-mails with very small attachments. - Testing download speed on Speedtest.net, measure stable full speed. I can't: - Testing upload speed on Speedtest.net. Upload stuck.. - Save/send email messages with big (128k) attachment, independent from e-mail provider or e-mail box. THIS IS NOT A HARDWARE/CABLE/CARD OR OTHER NETWORK DEVICES PROBLEM! When I boot from a Linux Live CD, without ANY hardware change, all data sending, testing works correctly, at full speed. I have tried already in Win 7: - Disable Windows/3rd party Firewall completely - Reset IP stack parameters (netsh int ip reset c:\resetlog.txt) - Computer restore - Reinstall LAN driver When I inspect the packets in Wireshark in Windows, I see lot's of (maybe 60% of sent packets) "TCP Retransmission". Sometimes receive "TCP Dup Ack" or "TCP Out-of-Order". Linux don't do this. Thank you for the help.

• One workstation gets slow access to the server, but others are fast

  - by Mike Hanson

  I've just setup a machine with Windows Server 2008. It hosts various services, like IIS, POP3, SMTP, Music for Squeezeboxes, VNC. All was working well for the first week or so. One day I needed to create a mapped drive on the server, so it could access files on my workstation. Windows indicated that Network Discovery was needed, so I turned it on with the "Home / Office" option (rather than "Public"). This may be coincidence, but since that time I've been having troubles accessing various services from my main workstation (running Windows 7/64): POP3 continued working correctly, but SMTP was delayed or failed entirely. (Telnet took 20 seconds to connect, but Outlook would never send messages.) VNC failed entirely. I reinstalled it on the server, and now it works but feels sluggish. The music web server was extremely delayed and usually failed. I tried reinstalling, and now it takes about 30 seconds to show the page name on the browser tab, and another 30 seconds to display any page contents. Other machines on the local network seem fine, as do machines connected via the Internet. I don't believe I changed anything on my own machine that would cause this. I considered the possibility that my anti-virus was involved, so I uninstalled AVG (commercial version), but that didn't help. I installed Norton 360 after that, and it didn't complain of viruses on my machine, and the delays remained. Because only my machine is affect, I'm tempted to blame it, except that reinstalling software on the server improved the situation, so there is almost certainly something going on with the server too. The firewall has all the necessary ports open, and it works fine for the other workstations (including external machines connected via the Internet), which indicates that it should be OK. Any ideas?

• Linux: Three default gateways?

  - by Daniel

  My server has three default gateways, how can that be? Shouldn't there be one default gw? I have three NICs, each attached to a separate subnet: server1:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.5.0.0 * 255.255.255.224 U 0 0 0 eth3 localnet * 255.255.255.224 U 0 0 0 eth0 192.168.8.0 * 255.255.255.192 U 0 0 0 eth1 default 10.5.0.1 0.0.0.0 UG 0 0 0 eth3 default 192.168.8.1 0.0.0.0 UG 0 0 0 eth1 default 10.1.0.1 0.0.0.0 UG 0 0 0 eth0 Sometimes, I can't ping a host on the Internet, sometimes I can. What I want is traffic to the Internet (0.0.0.0) routed through a specific NIC. Can I just add a route for 0.0.0.0 and default gw to one of the eth0-3 interfaces? Will it break my connection? I'm using Debian, here is my /etc/network/interfaces: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 iface eth0 inet static address 10.1.0.4 netmask 255.255.255.224 network 10.1.0.0 broadcast 10.1.0.31 gateway 10.1.0.1 allow-hotplug eth1 iface eth1 inet static address 192.168.8.4 netmask 255.255.255.192 network 192.168.8.0 broadcast 192.168.8.63 gateway 192.168.8.1 allow-hotplug eth3 iface eth3 inet static address 10.5.0.4 netmask 255.255.255.224 network 10.5.0.0 broadcast 10.5.0.31 gateway 10.5.0.1

• OSX server setup suggestions

  - by Tom

  I am looking into the possibility to setup an OSX server for my employees, and would like some input on what is the best approach to meet my needs, and perhaps some suggestions if I am moving in the wrong direction. I am thinking of a Mac Mini OSX server, and are not sure if my needs will be met, and what possibilities are out there. I want these capabilities: - Groups/Users managed on server - Shared folders and private folders for users/groups - Access to activated services - Server hosting software for the users (developing tools ++) - Similar to Windows Terminal Server - Virtual desktop environment (both local and over internet/VPN) - Possible to access trough Mac and Windows The reason I am looking at OSX server is that my employees almost only work in OSX environment, and I want to offer the capabilities to logon to the server trough some kind of terminal software, and have full access to their work OSX environment and software on their mac or pc, from anywhere they might be. Instead of having to have multiple setups and need for spending alot of time installing and setting up needed software on every client. This is a small business, where some work on local network, and others from the internet, preferably trough VPN. But a terminal server solution, that are fast and easy to manage would be perfect for our needs. So if anyone have any experience with a similar setup, please let me know what you did, and your experiences with your setup.

• IPtables and Remote Desktop with Proxy

  - by Sebastian

  So I setup a windows 2008 web server R2 on VirtualBox. Currently using Bridged Network. I can remote desktop to the machine hosting the VM (10.0.0.183) but cannot remote desktop to the VM itself (10.0.0.195). The remote port on the VM set to 5003. VM setup to accept remote connections (windows side). We also use a proxy for our internet, and I added these rules under NAT. (centOS 5) on our proxy box. -A INPUT -p tcp --dport 3389 -j ACCEPT -A REROUTING -i ppp0 -p tcp --dport 3389 -j REDIRECT --to-port 5003 -A FORWARD -d 10.0.0.195 --dport 5003 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT I've been trying for hours and hours and just cannot get it to work. I also used freedns so that we can use a domain name to connect too this VM over the internet. (the DNS points to our external IP address). If we don't get this right we will have to purchase a PPoE from an ISP to connect to this VM remotely, but I know that there is an alternative route if I can just get this port forwarding right!

• Server taking too long to respond error

  - by DCJones

  Hi, This is my first post on serverFault and my first entry in to web server configuration. The hardware and software. CPU: GenuineIntel, Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz OS: Linux 2.6.18-128.el5 Memory: 2Gb Background. I am running a small database (MySQL), around 1000 records with each record containing 44 fields. At the start of each day “00:01” the tables are cleared and populated with fresh data. The are 10 remote PCs all running Winodws XP and Firefox internet browser. All remote PC’s are connected to the internet using a min 4Gb broadband connection. Each remote PC runs a URL which displays a dynamic page of data which is refreshed every 20 seconds. This is a continual process 24 hours a day. I problem I am having is on odd occasions throughout the day the PC browser error with “Server taking too long to respond error”. What I am trying to find our is if I have the correct setting in the httpd.conf file on the server. Any help or advice anyone can provide would be very helpful. Best regards Dereck Server config file: httpd.conf ServerRoot "/etc/httpd" PidFile run/httpd.pid Timeout 120 KeepAlive On MaxKeepAliveRequests 200 KeepAliveTimeout 5 StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 256 MaxClients 254 MaxRequestsPerChild 4000 StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 150 ThreadsPerChild 25 MaxRequestsPerChild 0

• Local traffic through VPN, global traffic through WAN

  - by ikonoma

  I have an issue with my internet connection. I am using VPN (Aventail Client) to access the local resources. When connected to VPN the Internet traffic passes through it, not through my LAN or Wi-Fi network. I would like to change the routing table to use the Wi-Fi adapter of the PC for WAN traffic. I have routing file, which works very well and routes the traffic in this way, but only when I am physically connected to the local network through LAN. But I can't set it to work with the VPN connection, because I have no gateway when I am connected to it. Etc this in bold is missing. What to do? route change 0.0.0.0 mask 0.0.0.0 172.16.76.1 metric 200 if 12 route change 0.0.0.0 mask 0.0.0.0 10.44.2.1 metric 400 if 11 route add 150.251.0.0 mask 255.255.0.0 10.44.2.1 metric 100 if 11 route add 10.0.0.0 mask 255.0.0.0 10.44.2.1 metric 100 if 11 pause
