• WRT54G - how use port forwarding and VNC

  - by unknown (yahoo)

  Since I have my home network behind a WRT54G, the router has an external "real" IP address, and the PCs behind it have 192.168.xxx.xxx addresses. I would like to be able to control one of them remotely - preferably using UltraVNC, but I am open to suggestions. Since I can't directly address that PC from the internet, I figured I could address a port on my router and have the traffic forwarded to the PC (and the same in the reverse direction). Is that feasible? Can anyone tell me how to do it (or point me to an URL that does)? Thanks

• an attempt was made to logon, but the network logon service was not started

  - by RodH257

  We've recently had a catastrophic raid failure on our servers, which were being backed up with shadow protect. After 3 days of copying I finally got our file server back in a VM. As we used a 'virtualboot' for the file server in the meantime, I effectively had two copies of the server on the network at once. In order to copy back the files that changed, I tried to rename the file server, and change its IP address (I should also mention, the file server is a backup DC). When I renamed it, it came up with an error, so I rebooted. Now I can't login, it says "an attempt was made to logon, but the network logon service was not started" I don't care if I have to recreate the Vm and reinstall windows, but I would like to be able to get the files off this VM. How can I get access to it?

• Network printing -- setting up and printing over network using Mac OS X

  - by crippledlambda

  I've connected a USB printer to a Mac OS X (10.4) machine -- this computer is connected to a network with a registered IP address -- and enabled sharing through the System Preferences setting (under "Shared" and "Print & Fax". Is this printer shared through the Bonjour or CUPS protocol (does it matter that I know)? How do I sent a print job to this computer (also from a 10.4 OS X machine)? It does not show up in the list of printers in the Default Network when I go to "add printer"; do I need to do anything else (on either machine)? Thanks much!

• Access virtualhosts over LAN (Also in xpmode (Virtual PC))

  - by Pheter

  Hi, I am running Wamp on my computer (the host). I have set up several virtualhosts in apache and they are working fine when I access them from the same computer (host). I have installed Windows XPMode on my computer (which is running windows 7). XPMode (which uses Virtual PC) is set up to use a NAT network. The network in XPMode is working fine, and I can access the host PC via the IP address 192.168.1.5, just as I would if I was using any physical computer on the same network. I can view all the web pages at 192.168.1.5 and it's subdirectories. However, I cannot access any of the subdomains that are configured in the virtualhosts of the host computer. How can I access the subdomains? I don't think that the fact that I am using XPMode and am using a virtualized OS has anything to do with it, but I thought that it was worth mentioning.

• Error: "failed to connect to wpa_supplicant - wpa_ctrl_open no such file or directory" using netcfg with wpa_supplicant

  - by user1576628

  I'm trying to set up netcfg so that I can finish installing Arch Linux (using the instructions from the Beginners' Guide and netcfg) and I passed over what was meant to be a short step. Open wifi-menu, select network, enter password. After multiple attempts, I decided to edit the profile manually, which yielded no improvement. Eventually I decided to use netfcg with the more familiar wpa_supplicant. My /etc/wpa_supplicant.conf file is as follows: network={ ssid="my_ssid" #psk="my_wireless_passcode" psk="my_wireless_passcode_hex" } (Replacing generic names with my actual ssid and psk.) And my /etc/network.d/wpa_suppl file reads: CONNECTION='wireless' DESCRIPTION='A wpa_supplicant configuration based wireless connection' INTERFACE='wlan0' SECURITY='wpa-config' WPA_CONF='/etc/wpa_supplicant.conf' IP='dhcp' My ssid is not hidden, wlan0 is the proper interface, and wpa_supplicant works fine on its own, but using netcfg wpa_suppl, it returns failed to connect to wpa_supplicant - wpa_ctrl_open no such file or directory about twelve times before finally telling me the authentication failed. What can I do to fix this?

• Fedora to Fedora remote desktop does not work (connection closed error, even after setting everything up)

  - by jonderry

  I'm trying to use remote desktop on my laptop (running Fedora) to my desktop (also running Fedora) on the same local network. I configured Remote Desktop on my desktop via System - Preferences - Remote Desktop, verified that the port is open by nmap, and attempted to connect from my laptop via vinagre (also tried appending :5900 for the port, and using the ip address). In all cases, the connection fails with a popup that says "Connection closed\n Connection to host was closed." EDIT: I am able to use vinagre from the desktop to remote desktop into itself, just not from one machine to the other. I tried vncviewer and a similar problem occurs (unable connect to socket: No route to host (113))

• Windows Network Load Balancing on ESX Cluster with Dell PowerConnect stacks

  - by dunxd

  We recently switched out our Cisco 6500 core switch for a pair of Dell PowerConnect 6248 stacks. Since then, our Network Load Balanced Sharepoint, which runs on two virtual machines on an ESX cluster has been behaving very poorly. The symptoms are that opening and saving documents stored in sharepoint takes a very very long time. There are no errors showing up on the Sharepoint servers or SQL server, just a lot of annoyed users. Initially I thought there was no way NLB could cause this, but as soon as we repointed the DNS records for our intranet to the ip address of one of the web front ends, the problems disappeared. We suspect there is an issue related to multicast in the Dell configs - NLB is configured for multicast, but not IGMP. Has anyone got a similar set up to us and fixed this sort of issue? Sharepoint on VMware ESX, with Dell PowerConnect switches.

• TMG Forefront Proxy blocking internal HTTP requests

  - by Pascal

  I have TMG Forefront with Proxy installed and configured. However, whenever I make internal HTTP requested to servers on the internal network with a fully qualified dns name, the proxy denies the connection. Denied Connection FRW-02 18/03/2011 20:06:37 Log type: Web Proxy (Forward) Status: 12202 Forefront TMG denied the specified Uniform Resource Locator (URL). Rule: Default rule Source: Internal (10.50.75.21:21492) Destination: Internal (10.50.75.10:8080) Request: GET http://app-01.mydomain.com.br:9871/internalwebserver_deploy/MyServiceService.svc?wsdl Filter information: Req ID: 0a157279; Compression: client=No, server=No, compress rate=0% decompress rate=0% Protocol: http User: anonymous How can I get around this block? This is an internal call, so it should block it. If I use only http://app-01:9871/internalwebserver_deploy/MyServiceService.svc?wsdl, without the domain after the server name, then it doesn't get blocked. 10.50.75.10 is the firewall's ip, and the internal network's gateway.

• What's required for a nameserver to be registered?

  - by Lin

  I'm trying to change nameservers for some of my domains at GoDaddy, but I occasionally run into "Nameserver not registered" problems, and then I'm not allowed to set the nameservers. Here are the cases I've tried, and I still don't understand what it takes to have a registered nameserver. With ns1 and ns2 pointing to my nameservers, I can set the nameservers successfully when I set up domains as follows: Host Summary entries for ns1 and ns2 at GoDaddy .co.cc domains with A records for ONLY ns1 and ns2 Hosted with other nameservers. Have only A records for ns1 and ns2 But these do NOT work (nameserver not registered error): .info domains at GoDaddy with A records for ONLY ns1 and ns2 Hosts with dyndns.org that point to IP of nameservers Also, when I dig any domains hosted at my nameservers using any of the above, I get the correct response. So what's the deal here? Why do the last two cases get "nameserver not registered errors"? Thanks!

• Looking for a manual/how-to for installing a Canon iRunner 210s network printer

  - by Ssvarc

  A client has a Canon iRunner210S and is complaining about slow print speeds. I've searched for a install manual online but came up empty. A call to Canon technical referred me to their dealer network for service, as as informing me that there isn't a manual available on their website. Anyone know how to install these and/or have a link to a manual? The current setup has the printers on a LAN Manager printer port instead of on straight IP ports. Is this normal for this printer? And what exactly are Lan Manager ports (based on my research, they appear to be a way to authenticate a connection)?

• Double default gateway ubuntu server

  - by Elena

  Hi, I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy When I restart /etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway. But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network. I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?

• How to make xxx.one.com load content from yyy.two.com

  - by Roy Peleg

  Hello, I'm currently in need to have xxx.one.com load the content of yyy.two.com. That means that when someone will enter xxx.one.com they'll actually see the content of yyy.two.com (URL in the browser won't change and will remain xxx.one.com). The domains are hosted on separate hosting company. yyy.two.com is on a cPanel and xxx.one.com is on an unknown hosting plan, though I can get its details. yyy.two.com have the same IP of www.two.com and this cannot be changed (as the hosting company told me). Any ideas on how do I tackle this issue? Thanks, Roy

• Installing OpenSSL that supports SNI along with previous version of OpenSSL

  - by gh0sT

  So I learned that to host multiple HTTPS websites on the same IP address you need an OpenSSL version that supports SNI (0.9.8f and higher). My RHEL5 box currently has 0.9.8e and Apache version httpd-2.2.26-2.el5. According to a same question here it's not a good idea to replace the original version of OpenSSL and instead to have a parallel installation. It however doesn't explicitly mention how to achieve this. So my questions are: How do I have an alternate installation of OpenSSL without breaking the system? How do I make Apache to use this version of OpenSSL and not the original one? A detailed guide would be extremely helpful.

• Wireless Repeating with Netgear N750 (WNDR4300)

  - by jomo1911

  I have a Netgear N750 as my main router, which connects to the internet via a modem. I have a second Netgear N750 which I want to use to repeat the wireless signal of the main router. I logged in to routerlogin of my main router (192.168.1.1) and set up the "Wireless Repeating Function". I set it as the "Wireless Base Station" and filled in the MAC adress of my second Netgear N750. Then I logged in to routerlogn of my second router and set it up as the "Wireless Repeater", I gave it the IP 192.168.1.11 and filled in the MAC adress of the base station. During the setup of the second router (Repeater) I had to disable all security functions. If I connect to the repeaters' WLAN signal, I get no internet connection. Maybe you can help me, thanks

• Setup Exchange 2007 ActiveSync web application on a separate server

  - by mwillmott

  Hello, I have Exchange 2007 installed on SBS 2008. I also run a web server on the network. I only have one static IP and all traffic trough port 443 is routed to the webserver. I would like to publish the ActiveSync application externally. If i temporarily route 443 traffic to the SBS then it is published (along with owa and everything else which i don't want). Is there a way to host the ActiveSync application on the web server (Server 2008 with IIS7) or to get it to route traffic meant for the ActiveSync application? I have tried creating a site on the webserver which uses the ActiveSync folder on the SBS but that does not seem to work. Thanks, Michael

• MySQL replication Slave_IO_Running: No

  - by Christy

  Hi all, I have two servers that I am trying to get replication of one database between. I found a setup guide on sourceforge that I followed and I have tried various other settings since then, but no matter what I do, when I start the slave, the 'Slave_IO_Running' setting is always No.... I have no idea why or what to look at, any suggestions are appreciated. The slave setup was: CHANGE MASTER TO MASTER_HOST='myserver.mydomain.net', MASTER_USER='slave_user', 'MASTER_PASSWORD='mypassword', 'MASTER_LOG_FILE='mysql-bin.000011', MASTER_LOG_POS=1368363 (last data from today, trying to do setup again. I deleted and recreated the database on the slave from a new dump and tried to redo the setup.) I have slave_user setup for %, localhost, and the specific IP of the slave computer but nothing seems to be working... Thanks in advance for any advice or suggestions

• Specify IPSEC port range using ipsec-tools

  - by Sandman4

  Is it possible to require IPSEC on a port range ? I want to require IPSEC for all incoming connections except a few public ports like 80 and 443, but don't want to restrict outgoing connections. My SPD rules would look like: spdadd 0.0.0.0/0 0.0.0.0/0[80] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[443] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[0....32767] tcp -P in esp/require/transport; In setkey manpage I see IP ranges, but no mention of port ranges. (The idea is to use IPSEC as a sort of VPN to protect internal communications between multiple servers. Instead of configuring permissions basing on source IPs, or configuring specific ports, I want to demand IPSEC on anything which is not meant to be public - I feel it's less error-prone this way.)

• Dynamic DNS at freedns.afraid.org using a Fritz!Box

  - by kai

  I am having some trouble setting up Dynamic DNS with my Fritz!Box 7360. I have set up the Dynamic DNS page with (this is translated from German, so might be worded a bit differently): [x] Use dynamic DNS Dynamic DNS Provider: User defined Update-URL: https://freedns.afraid.org/dynamic/update.php?MY-DIRECT-URL-KEY Domain Name: mydomain.crabdance.com User Name: myusername Password: mypassword Now on the FritzBox status page, it says: Dynamic DNS: activated, mydomain.crabdance.com, Status: Account temprarily deactivated When I check back on http://freedns.afraid.org, my IP address never changes. Is there any way to fix this? Note my router is on an IPv6 network (m-net), with IPv4 only through DS-Lite. I'm not sure whether this affects anything. Update: Following the guide here (putting myusername instead of MY-DIRECT-URL-KEY) hasn't given any succes. However, the status field has changed slightly: Dynamic DNS: activated, mydomain.crabdance.com, Status: unknown

• Unknown and strange RDP successful logins in EventViewer

  - by Yousef

  I have a Windows Server 2008 R2 with a valid IP, and recently I've found hundreds of unknown and strange RDP successful logins logged in EventViewer. Here are some details: They are not similar to normal logins, they happen like every second in a while even when I myself am logged in to the server. Event reads "Remote Desktop Services: User authentication succeeded" in "Microsoft-Windows-TerminalServices-RemoteConnectionManager/Operational", Event ID 1149 They seem to use some random user accounts without a domain name. I'm pretty sure that I don't have those local user accounts, and the server doesn't belong to any domain. Legitimate RDP logins have a valid user account and workgroup name, but those logins use unknown user names without any workgroup. Support staff couldn't help me and I'm very curious what are these strange logins. Are they some sort of brute force attack? so why does it read "Successful"? Am I being hacked? Why do they keep happening continually?

• DD-WRT VPN error 800?

  - by MrZombie

  I have set up a router with DD-WRT Mega on my Asus WL-500gP V2, and I can't connect to the VPN service. I have set it up according to the configuration on the DD-WRT wiki, so the server IP is set to 192.168.1.1, which is the address of the router, and I set up the client addresses to be 192.168.1.20-29. My chap secrets are set up correctly, and still, I get an error 800 on windows XP. As far as I can tell, it means my network is unreachable. The server responds to ping.

• WAMP, DD-WRT, Using DNSMasq to access multiple virtual hosts via aliases on local network

  - by christian

  I've updated my question to coincide with my progress I am attempting to configure WAMP on my development machine. I would like to use it in conjunction with DD-WRT's DNSMasq feature to access multiple virtual hosts via aliases (dev1.local,dev2.local,etc.) over my local wireless network. I have followed the following tutorial which allows me to setup virtual hosts and access on local network by ip addresses. http://www.logicspot.com/web-development-2/viewing-a-locally-hosted-website-with-your-smartphone/ I've got this up and running. For simplicity sake I'd still like to setup DNSMasq to connect via aliases. I have followed the following tutorial http://www.question-defense.com/2008/12/29/add-static-dns-entries-to-dd-wrt-router-firmware And the aliases load on my development machine, but I can not access via the aliases on my mobile devices connected to the local network. I can however access via IPs. Thanks for any help you can provide

• Lighttpd proxy module - use with hostname

  - by k_wave

  I have to proxy a site which is hosted on an external webspace through my lighty on example.org. My config so far: $HTTP["url"] =~ "^/webmail" { proxy.server = ("/webmail/" => ( # this entry should link to example2.org ("host" => "1.2.3.4", "port" => 80) )) } The webspace provider has configured my domain as vhost. So if i access http://1.2.3.4/webmail/ lighttpd will only deliver the main site of the webspace provider which says "Site example.org was not found on our server." Any suggestions how i have to configure lighty to proxy sites that are only hosted as vhost (and do not have an ip on their own)?
