• How do I know when my on-board ethernet is dead? (Realtek 8112L LAN controller w/ AI NET2 )

  - by Usagi

  So I have an ASUS P7P55D-E Pro motherboard. It has an on-board Realtek 8112L LAN controller w/ AI NET2. I suspect that my LAN controller is dead but I don't really know for sure. This is what I know thus far: Everything was working, I have a triple booted system and ethernet was functional under Linux, Win7, and OSX. My ethernet is no longer functional under all three of the operating systems. I was experiencing random momentary internet outages before everything finally went dark. I don't know much about the AI NET BIOS tool but I believe it just checks for ethernet problems before you boot into an operating system. In any case, it doesn't find a connection upon boot. I've checked the connection on a couple of other machines and everything worked fine. I think I already know the answer to my question, but are there any other possible explanations, or is it dead?

• How to Install Broadcom Wireless Drivers (BCM43xx)

  - by Fer1805

  I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc. Edit: For the command: "lspci | grep Network", I get the following message: 06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) For the command: iwconfig, i get the following: lo no wireless extensions. eth0 no wireless extensions. When i follow the following steps (from the above link), there are a NO error message at all: open the 'Synaptic Package Manager' and search for bcm uninstall the bcm-kernel-source package make sure that the firmware-b43-installer and the b43-fwcutter packages are installed type into terminal: cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl' (you may want to copy this) and see if the term blacklist bcm43xx is there if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf put a # in front of the line: blacklist bcm43xx then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly). reboot 'End of procedure' Before (not ubuntu 11.04), if i wanted to connect wireles, i just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done. Now, the only options i see are: Wired Network Auto Eth0 Disconnect VPN Enable networking Connection information Edit connection. lspci -vnn | grep Network showed: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] hope above info is enough for your help.

• Oracle 11g network configuration

  - by Kylo

  Hi, I installed Oracle 11g Enterprise Edition on my Windows 7 Pro. My problem is that I cannot log into database from other host (local network). When I connect to database using Oracle SQLdeveloper everything is ok as long as I specify 'localhost' in connection configuration. However, when I change it to '192.168.0.190' which is my host IP address I get 'The Network Adapter could not establish the connection'. I get the same error when logging in from other host in local network. What is the problem?

• IIS + PHP + Page with lots of images = Intermittent 403 errors

  - by samJL

  I am using an up-to-date Server 2008 R2 Datacenter, running IIS 7.5 and PHP 5.3.6/FastCGI On PHP pages with lots of images (60+), some of the images fail to load It is not always the same images-- on each page refresh an image that worked previously may not load, while an image that did not now does Looking at the Net tab in Firebug reveals that the failing image requests are 403 errors All of the images are located on the server in question, and the images directory has the correct permissions I believe this problem is the result of a limit on requests All of my attempts at researching this problem point to maxConnections setting in IIS, yet mine is set at the highest/default of 4294967295 (maxBandwidth too) I am also running a ColdFusion site on the same IIS installation, and it does not suffer from 403's on pages with lots of images I am left thinking that there is another connection limit (in PHP or FastCGI?) overriding the IIS connection limit I don't see anything that looks like a request limit in the php.ini, what am I missing? Any help would be appreciated, thank you

• How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

  - by Timbo

  I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

• How to forward http traffic through a specific network adapter.

  - by user18129

  i have the following scenario. Two laptops are connected via a router through the Ethernet ports. These two computers need to be able to communicate together. One computer also needs to access the internet through a different adapter (i.e. we will taking these two laptops two various sites where by the most common type of internet access will be wireless).In isolation all of the various adapters work fine (i.e. the internal network works fine, and the wireless connects to the internet). However,we try to turn on all of the adapters at the same time,the following occurs: If we bridge the two network connections together on the "Server" -The internet connection doesn't work through the wireless If we don't bridge the connections The internet connections don't work It seems like http traffic is trying to be sent through the Ethernet adapter (which of course is not connected to an internet connection). How can we solve this?

• If Nvidia Shield can stream a game via wifi, why can I not do the same via ethernet to any other PC?

  - by Enigma

  I think it absurd that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth. I can only assume that there must be some reason behind this or a limitation preventing this, but what? 150mbps wifi is in no way superior to a 1000mbps LAN connection aside from well wireless mobility. Not only that but I have a secondary laptop and desktop which should by hardware comparison completely outperform anything the Tegra in the Nvidia Shield can do. Is this all just a marketing scheme to force people to buy the shield for the streaming benefit? Chief among these is that NVIDIA’s Shield handheld game console will be getting a microconsole-like mode, dubbed “Shield Console Mode”, that will allow the handheld to be converted into a more traditional TV-connected console. In console mode Shield can be controlled with a Bluetooth controller, and in accordance with the higher resolution of TVs will accept 1080p game streaming from a suitably equipped PC, versus 720p in handheld mode. With that said 1080p streaming will require additional bandwidth, and while 720p can be done over WiFi NVIDIA will be requiring a hardline GigE connection for 1080p streaming (note that Shield doesn’t have Ethernet, so this is presumably being done over USB). Streaming aside, in console mode Shield will also support its traditional local gaming/application functionality. - http://www.anandtech.com/show/7435/nvidia-consolidates-game-streaming-tech-under-gamestream-brand-announces-shield-console-mode ^ This is not acceptable for me for a number of reasons not to mention the ridiculousness of having a little screen+controller unit sitting there while using a secondary controller and screen instead. That kind of redundant absurdity exemplifies how wrong of a solution that is. They need a second product for this solution without the screen or controller for it to make sense... at which point your just buying a little computer that does what most other larger computers do better. All that is required, by my understanding, is the ability to decode H.264 video compression and transmit control/feedback so by any logical comparison, one (Nvidia especially) should have no difficulty in creating an application for PC's (win32/64 environment) that does the exact same thing their android app does. I have 2 video cards capable of streaming (encoding) H.264 so by right they must be capable of decoding it I would think. I haven't found anything stating plans to allow non-shield owners to do this. Can a third party create this software or does it hinge on some limitation that only Nvidia can overcome? (*) - perhaps this isn't the first but afaik it is the first complete package.

• Server 2003 slow share.

  - by G V

  I am running an 03 box with shares active. When uploading to the share, the speed is average. About 15-20 mbps.. But when you think about it, it is bad because it is a direct connection to a couple machines. When uploading to another server the connection speed is twice that of the direct storage. When uploading s massive folder, 250 GB, the upload will start as normal, but as it progresses it drops in speed. Now it is sitting at around 2-7 Mbps. Any ideas on how i can boost the transfer rate? On a side note, the download speed is great. It is a speed that you would expect from this setup, the main problem is uploading and what is causing the extreme slowness in speeds. Any help would be great.

• How to control messages to the same port from different emitters?

  - by Alex In Paris

  Scene: A company has many factories X, each emits a message to the same receive port in a Biztalk server Y; if all messages are processed without much delay, each will trigger an outgoing message to another system Z. Problem: Sometimes a factory loses its connection for a half-day or more and, when the connection is reestablished, thousands of messages get emitted. Now, the messages still get processed well by Y (Biztalk can easily handle the load) but system Z can't handle the flood and may lock up and severely delay the processing of all other messages from the other X. What is the solution? Creating multiple receive locations that permits us to pause one X or another would lose us information if the factory isn't smart enough to know whether the message was received or not. What is the basic pattern to apply in Biztalk for this problem? Would some throttling parameters help to limit the flow from any one X? Or are their techniques on the end part of Y which I should use instead ? I would prefer this last one since I can be confident that the message box will remember any failures, which could then be resumed.

• How do I use XQuartz with ssh on OS X?

  - by cwd

  I've downloaded the latest stable version of XQuartz on my Snow Leopard machine, and I'm trying to make an ssh connection with X forwarding but X11 keeps opening. How can I get OS X to use XQuartz? I had X11 installed I downloaded and installed XQuartz X11 is not open / running XQuartz is open and running I try and connect to a remote system using iTerm2: ssh user@remote -X X11 opens. XQuartz is still open, but I doubt it is doing anything. I also tried moving X11 to the trash but then the ssh connection will not complete, even though XQuartz is open. I also get the two warnings which I don't understand how to fix, even after reading the ssh man page. Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding.

• eCryptfs on ubuntu server : How to keep the home mounted without being over ssh?

  - by Bebeoix

  I have a daemon program who need to read in a file who is saved somewhere in my home folder. But every time I close my ssh connection, this daemon can't read the file because it appear that eCryptfs unmount the home. Maybe there is an option to force eCryptfs to not only mount with an ssh connection ? I didn't found it. Thanks. PS : I know this thread, http://askubuntu.com/questions/165608/why-is-ecryptfs-only-mounting-private-home-directory-over-ssh, but this is not the proper/good way to deal with the request.

• preloading RSS contents in thunderbird, before actually reading them

  - by Berry Tsakala

  i have thunderbird 3.x, and i'm subscribed to several RSS feeds. How can I tell thunderbird to load/download any new RSS items in the background? The usual behavior with RSS feeds is that it download the headrs, or few introductory lines from the contents, but only when i'm clicking a feed item it starts loading "for real". I really want to receive the feeds and not to wait for them to load, the same way i receive emails in any email client - all messages are fully downloaded at once. there could be several reasons, BTW. - e.g. if i have short connection time, i'd rather connect, sync everything at once, and read it later. - or if i have a slow wifi connection, it's annoying to wait for each and every message, but the computer is idle while reading.. thanks

• Ubuntu Studio 10.4 boots to terminal mode only

  - by Don

  I did clean install from ISO DVD. It boots only to command line asking for login. After I login I enter STARTX and desktop appears and some of the studd actually works, but there are a lot of problems: there is no way to reboot or shut down except to stopx/logoff and enter shutdown sound system doesn't respond pulse audio volume control gives "connection failed, connection refused" DVD drives not available GDebi Package installer is grayed out and so I can't use it (but synaptic package manager works OK) Software Center won't start when clicked -- it just stops trying DBus cant run because it says /usr/local/var/run/dbus/system_bus_socket file not found (also /var/run/dbus/system_bus_socket file not found) There's just a lot of things wrong and I can't help but think something is missing or was mis-coded in the distro so that there are typos in some script somewhere. If anyone can tell me where to begin to untangle this mess I'd appreciate it, but I think it all begins when it can't start the GUI automatically and I need to enter STARTX.

• Blocked Chrome by Company's Proxy

  - by gol.d.ace

  Chrome has just suddenly being blocked by my company for accessing internet. Instead, IE still works fine. It blocks the connection, the error says that my Chrome connection is timeout & the server is not responding Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out). I guess the reason behind this is to standardize all user's browser for only using IE for security reason. I have tried to change the user-agent string (--user-agent="... ") so that the Chrome will pretend to be as IE. and yet, still not working! Could anyone shed my problem here? IE is just not comfortable so-called for surfing the web!

• Why is file sharing over internet still working, despite all firewall exceptions for filesharing being disabled?

  - by Triynko

  Every exception in my windows server firewall that starts with "File and Printer Sharing" is disabled (ordered by name, so that includes domain, public (active), and private profiles). The Network and Sharing Center's options for everything except password protected sharing are off. Why would I still be able to access a network share on that server via an address like "\\my.server.com\" over the internet? The firewall is on for all profiles and blocking incoming connections by default. A "netstat -an" command on the server reveals the share connection is occurring over port 445 (SMB). I restarted the client to ensure it was actually re-establishing a new connection successfully. Is the "Password protected sharing: On" option in Network and Sharing Center bypassing the firewall restrictions, or adding some other exception somewhere that I'm missing? EDIT: "Custom" rules are not the problem. It's the "built-in" rules for Terminal Services that was the problem. Can you believe port 445 (File Sharing Port) has to be wide open to the internet to use Terminal Services Licensing?)

• Extend university wifi network

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want?

• Spawning HTTPD processes

  - by felix001

  Can any confirm how Apache spawns new children ? As in if I connect to a webserver (HTTP 1.0 / no keep alive) and issue a HTTP /GET I will be spawned a new HTTPD child. If then issue another HTTP /GET then a new TCP connection will be built. However will I use the same child process of would I spawn a new one ? Also if I was using HTTP 1.1 (with keep-alive) and reused the same TCP connection, would the httpd process/spawning be any different to that if I wasnt using keepalive ? Thanks,

• How can I restrict my mates to stop downloading?

  - by user239295

  We are sharing an internet broadband connection with 6 users at a place we live. We get 20 gb fup ( Fair usage policy) with 2 mbps speed from the ISP after the 20 gb is consumed the speed comes down to 512 kbps very difficult to browse any page. The problem is we cannot track which user/mate is downloading and ending the FUP. it is very difficult to track so is there something that we can allot per user some amount of space like 2 gb of downloading or restrict all from downloading so that we can utilize all the fup till the end of the month. We are using this connection as wifi configured. A adsl router is configured as wifi and we all using all 6 laptops. No PC. Any help would be appreciated. I apologize if i am not clear with my question.

• Cisco: changing VTP mode server/client to transparent

  - by J. Smith

  I have around 40 L2 switches (2960, 3560, 3500, 3750) running in VTP client mode and one L3 switch (6500) running in VTP server mode, all connected together. I would like to switch everything in VTP transparent mode without any interruption of service. I've already test on a poc version with 3 switches (Catalyst 2950, 3560 and 3750). Using serial and SSH connection, it is seems working but i'm not sure it is enough representative compare to the real network. Knowing that the VTP Pruning is enabled, I am wondering what would be the best procedure to proceed the changement. I've read that we could lost connection by keeping it enabled. Should I change the server or clients first? Is it important to change the VTP domain and VTP Pruning parameters?

• How to connect to internet 2 or more pcs with an usb wifi adapter

  - by bhaoahd

  In one pc I have an USB Wifi adapter (Realtek RTL8187L Chipset), from there a 10 meters cable to an outdoor antenna. With that I connect to a public Access Point. Now I want to be able to connect more computers to internet using that same connection that comes from the outdoor antenna, what options do I have to do this? I do have another usb wifi adapter with a small omni antenna, and a router encore ENHWI-G/A. This router can be used as a Wifi AP, but it needs a modem that works with the RJ45 connector. Is there a way I could take internet from the outdoor antenna, and create another AP indoor using that router to "repeat" that wifi that comes from the outdoor antenna? If creating this second AP is not possible, should I use some sort of local network between computers, connect my main PC with the outdoor antenna, and share the connection through the lan? (I would really prefer to have a second AP indoor so I can connect other devices like a Palm, but I am not sure how could this be possible with this router and the usb wifi adapter)

• Can a consumer wireless router act as both a wireless client and access point?

  - by glibdud

  I'm going to be moving in the future, and integrating my home network into that of my landlord. I wish to maintain an isolated network while using his internet connection, so I'm planning on cascading my router off of his (WAN-to-LAN type configuration). Unfortunately, it looks like it might not be feasible to run a wire between the two. Therefore, I'd like to send my WAN connection over WiFi to his router. At my disposal, I have a WRT54GL (running Shibby's Tomato mod), and I just bought an Asus RT-N66U (I can be flexible with the firmware). My first thought was to set up the WRT as a wireless bridge, then run a wire between that and the N66U's WAN port. I'm reasonably sure I could make that work, but can I eliminate the WRT from the equation altogether? Can the N66U connect to the landlord's WiFi as a client, effectively using that as the WAN port, while simultaneously providing wireless access to my devices on an altogether different WLAN?
