  • Setting up 802.1X wireless connection on OSX

    - by hizki
    I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort (version 5.5.2). I am trying to connect to my university's wireless network, but it has a 802.1x security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my Mac? I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort (to version 5.5.2) it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password. Update: I have already tried to create a new "location", removed all the 802.1x user profiles and all the remembered networks, and made sure the in the TCP/IP tab 'Configure IPv4' is set to "Using DHCP". I also moved /Library/Preferences/SystemConfiguration/preferences.plist to my desktop in attempt to force the system to create a new set of settings. Still I can define the connection to work.

  • Different versions of iperf for windows give totally different results

    - by Albert Mata
    Measuring TCP output from a Windows client to Solaris server: WXP SP3 with iperf 1.7.0 -- returns an average around 90Mbit Same client, same server but iperf 2.0.5 for windows -- returns an average of 8.5 Mbit Similar discrepancies have been observed connecting to other servers (W2008, W2003) It's difficult to get to some conclusions when different versions of the same tool provide vastly different results. Example below: C:\tempiperf -v (from iperf.fr) iperf version 2.0.5 (08 Jul 2010) pthreads C:\tempiperf -c solaris10 Client connecting to solaris10, TCP port 5001 TCP window size: 64.0 KByte (default) [ 3] local 10.172.181.159 port 2124 connected with 10.172.180.209 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.2 sec 10.6 MBytes 8.74 Mbits/sec Abysmal perfomance, but now I test from the same host (Windows XP SP3 32bit and 100Mbit) to the same server (Solaris 10/sparc 64bit and 1Gbit running iperf 2.0.5 with default window of 48k) with the old iperf C:\temp1iperf -v iperf version 1.7.0 (13 Mar 2003) win32 threads C:\temp1iperf.exe -c solaris10 -w64k Client connecting to solaris10, TCP port 5001 TCP window size: 64.0 KByte [1208] local 10.172.181.159 port 2128 connected with 10.172.180.209 port 5001 [ ID] Interval Transfer Bandwidth [1208] 0.0-10.0 sec 112 MBytes 94.0 Mbits/sec So one iperf with a 64k window says 8.75Mbit and the old iperf with the same window size says 94.0Mbit. These results are constant through repeated tests. From my testing launching iperf(old) with window size "x" and iperf(new) with window size "x" instead of producing the same or very close results produce totally different results. The only difference I see is the old compiled as win32 threads vs. pthreads but parallelism (-P 10) appears to work in both. Anyone has a clue or can recommend a tool that gives results I can trust?? EDIT: Looking at traces from (old) iperf it sets the TCP Window Scale flag to 3 in the SYN packet, when I run the (new) iperf this is set to 0 in the initial packet. A quick analysis of the window size through the exchange shows the (old) iperf moving back and forth but mostly at 32k while the (new) iperf mostly keeps at 64k. Maybe it will help somebody to connect the dots.

  • Blender refuses to start

    - by Sekhemty
    I'm trying to run Blender under Linux, but I'm unable to do that, whenever I try I get some errors. I'm using Kubuntu 12.04 with KDE 4.11.1. This is my video card: ~$ lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV610/M74 [Mobility Radeon HD 2400 XT] I used to have installed the fglrx proprietary Catalyst drivers, but lately they gave me some system-wide problems and I had to revert to the open source Mesa drivers (I don't think that these details are important, but just in case, the whole story is here). Whit the fglrx drivers Blender was running fine, but now, whenever I try to start it, I get this error message (some parts are in italian, but I think that they are easily understandable): ~$ blender connect failed: No such file or directory Writing: /tmp/blender.crash.txt Errore di segmentazione (core dump creato) The content of /tmp/blender.crash.txt is as follows: # Blender 2.68 (sub 5), Revision: 60150 # backtrace /usr/lib/blender/blender() [0x877a41f] [0xb7756400] /usr/lib/i386-linux-gnu/libLLVM-3.0.so.1(_ZN4llvm3ARM8SPRClassC1Ev+0x15) [0xa8f4a9d5] /usr/lib/i386-linux-gnu/libLLVM-3.0.so.1(+0x25ca48) [0xa8eefa48] /lib/ld-linux.so.2(+0xeeab) [0xb7765eab] /lib/ld-linux.so.2(+0xef94) [0xb7765f94] /lib/ld-linux.so.2(+0x12fa6) [0xb7769fa6] /lib/ld-linux.so.2(+0xeccf) [0xb7765ccf] /lib/ld-linux.so.2(+0x127f4) [0xb77697f4] /lib/i386-linux-gnu/libdl.so.2(+0xbe9) [0xb4ff9be9] /lib/ld-linux.so.2(+0xeccf) [0xb7765ccf] /lib/i386-linux-gnu/libdl.so.2(+0x133a) [0xb4ffa33a] /lib/i386-linux-gnu/libdl.so.2(dlopen+0x47) [0xb4ff9c97] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x3cbf0) [0xb7717bf0] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x4079d) [0xb771b79d] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(+0x1a3aa) [0xb76f53aa] /usr/lib/i386-linux-gnu/mesa/libGL.so.1(glXQueryVersion+0x2e) [0xb76f0cee] /usr/lib/blender/blender(_ZN15GHOST_WindowX11C1EP15GHOST_SystemX11P9_XDisplayRK10STR_Stringiijj18GHOST_TWindowStatei25GHOST_TDrawingContextTypebbt+0x11c) [0x8f54aec] /usr/lib/blender/blender(_ZN15GHOST_SystemX1112createWindowERK10STR_Stringiijj18GHOST_TWindowState25GHOST_TDrawingContextTypebbti+0xd7) [0x8f4f4a7] /usr/lib/blender/blender(GHOST_CreateWindow+0xb6) [0x8f4cf86] /usr/lib/blender/blender(wm_window_add_ghostwindows+0x205) [0x8799be5] /usr/lib/blender/blender(WM_check+0x50) [0x877b670] /usr/lib/blender/blender(wm_homefile_read+0x111) [0x87859f1] /usr/lib/blender/blender(WM_init+0xd2) [0x8787872] /usr/lib/blender/blender(main+0xe6e) [0x873848e] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0xb4e694d3] /usr/lib/blender/blender() [0x8778a99] The only thing that I can guess from this report is that the mesa drivers are somewhat involved, as I already suspected, but I don't have a clue on what I need to do to try to solve the issue.

  • GNU screen multiuser mode is broken in OS X 10.6 (Snow Leopard)

    - by schustafa
    I'm using GNU screen for remote pair programming. Let's call the local account for the remote user 'pairpair'. I have the following lines in my .screenrc: multiuser on acladd pairpair I have run sudo chmod u+s /usr/bin/screen. However, when the remote user tries to connect to my screen with the command screen -r [my_account_name]/[pid_of_screen] I receive the following message: Attach attempt with bad pid(xxx) The pid listed in the error message matches the pid of the screen process run by the remote user. The remote user's screen process hangs; my screen session continues happily along after the error message disappears. I've tried using both the built-in screen (at /usr/bin/screen) and the screen available from MacPorts, but I get the same error in both cases. This worked on OS X 10.5 (Leopard). I've googled around for the error message, but most of the hits relate to some BSD bug from 2003 or so (which was fixed). Has anyone else seen this behavior? Does anyone have any idea how to make multiuser support in screen work in SL?

  • HP Officejet 4500 G510n-z Not Showing up in Remote Desktop (Terminal Services)

    - by Greg_the_Ant
    I installed this printer on a windows XP machine. First using the wireless option, and later using USB. In both cases when I connect to my other computer (also Windows XP) via terminal services and check printers in the local resources tab it does not show up on the remote session. I used to have a Samsung connected to my local computer over USB and and that worked fine over terminal services. Things I tried so far: I did read this page and installed the software fix on both computers: (Printers that use ports that do not begin with...) I installed the minimum HP software install on the remote computer and that didn't help either. I also tried running the add new printer wizard on the remote computer: I selected "local printer attached to this computer" and did not check the "automatically.." option. On the next page of the wizard I can select an option for "use the following port". I see options for TS001 through TS009 there. I'm assuming those are coming from the local machine. I tried clicking each one and then checking "have disk" and pointing it to C:\3be8dc611b11322e8ddf8a67\i386\msxpsdrv.inf 1 but for every single TS00.. port it says "The specified location does not contain information about your hardware." Any help would be greatly appreciated. I'm pretty stuck at this point. 1 C:\3be8dc611b11322e8ddf8a67 is the folder I extracted the HP driver software to after I downloaded it.

  • Error when connecting to shared Windows Printers

    - by TrueDuality
    I'm replacing our Windows 2003 print server with one running on Windows 2008 R2. I have connected and configured all of our printers and can successfully print to them from the server itself. All of the printers are shared and user's have permission to print on all of them. Whenever one of our clients attempts to connect through the shares they receive the following error message: Operation could not be completed (error 0x0000709). Double check the printer name and make sure that the printer is connected to the network. No messages are generated on the client Event Log nor is anything generated on the server. I have reinstalled the drivers as suggested by a few forum posts I came across and it didn't solve the issue. There are twelve different printer drivers and they are all experiencing this issue so I believe it is unrelated to the driver. I have disabled UAC on both the client and server since that has caused so many headaches before, but it too did not solve this problem. Does anyone have any idea what may be causing this?

  • New Computer won't boot up

    - by Reggie
    I brought new components and put a computer together. I installed win7(32bit) and everything was working as it should. However my case came with two USB3 front ports I could not connect because of motherboard did not support USB3, so I swapped out the board for a new motherboad with USB3 connection. Now I put everything back together but it won't bootup. "Memory Ok" light stay on. Motherboad LED is on. There is power, all fans are on but I got no display. There is no activity in back of the systems, none of the peripheral connection in the back are working. I have tried the following but to no avail. Reboot multiple times Unplug power and plug the power back Reset the CMOS battery..let it stays out for 10 minutes or more. Unplug all peripheral device but no luck Reset memory..... nothing happen The only thing I did not do was remove the cpu...but I unplug everything else. Please help, thank you.

  • Cisco VPN endpoints disconnecting from a VLAN

    - by dunxd
    I have a number of Cisco ASA 5505 and PIX 506e around the world acting as VPN endpoints. They connect to a Cisco VPN Concentrator 3000 at HQ. I am using EZVPN to set up the VPN (i.e. most of the config is central on the VPN Concentrator) The majority of endpoints work absolutely fine. However, there are three that do not. 2 ASAs and 1 PIX get disconnected from one of the VLANs on our network. This is the VLAN that my monitoring server runs on - so those endpoints look as if they have gone down. However, I can still ping the endpoints from our user VLAN. If I then SSH onto the endpoint, and do a ping to my monitoring server, the connection comes back. Then after about 10 minutes it stops working again. I've looked at the configuration of my endpoints, and I can't see any significant differences. One common feature is that the affected endpoints are connecting to the internet via retail quality routers. However, I don't see how this could affect traffic within a VPN tunnel. Any ideas or suggestions? I've also got a thread on Cisco's forums at https://supportforums.cisco.com/thread/344638. One other person has reported the same problem.

  • ownCloud WebDAV interface seems to be broken

  • Mysql can not resolve hostnames when checking privileges

    - by Fabio
    I'm going crazy to solve this. I have a mysql installation (on machine db.example.org) which doesn't resolve a given hostname. I gave privileges using hostnames i.e. GRANT USAGE ON *.* TO 'user'@'host1.example.org' IDENTIFIED BY PASSWORD 'secret' GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX ON `my_database`.* TO 'user'@'host1.example.org' However when I try to connect using mysql -u user -p -h db.example.org I obtain ERROR 1045 (28000): Access denied for user 'user'@'192.168.11.244' (using password: YES) I already checked for correct name resolution in the dns system: $ dig -x 192.168.11.244 ;; ANSWER SECTION: 244.11.168.192.in-addr.arpa. 68900 IN PTR host1.example.org. I've also checked for skip-name-resolve option in mysql variables in fact if I can access from another machine on the same subnet using hostname privileges. The only difference is that host1.example.org and db.example.org point the same ip on the same machine i.e. both db.example.org and host1.example.org have ip 192.168.11.244. In this way all the applications using that database can use the name db.example.org and we can move the data on other hosts (if needed) just by changing the dns record, leaving the application code unchanged. What should I do to solve this or at least to understand what's happening?

  • Lose internet connection, yet online games continue

    - by Mike
    For the past week or so, my internet connection has been anything but stable. Restarting my modem/router always fixes the problems, but since it has occurred so often, I'm noticing confusing patterns which I was hoping someone could help answer. My internet connection kicks out about 4-5 times a day. The sure-fire way to fix it is to restart my all-in-one modem/router. Sometimes I can diagnose the problem on my laptop which resets my wireless network adapter and fixes the problem, but not always. If that doesn't fix the problem, it usually reports that the connection between the modem and internet is the problem which requires a restart of the router. The odd thing which baffles me is that my connection is supposedly lost such that no browsers can connect to sites, yet things like online games still continue to play without issue. How is this possible? I thought maybe the game was running locally on my PC but that couldn't be the answer because I was still getting messages from other players. So my real question is: How can my internet browsers (firefox, chrome, even IE) lose connection to the internet, but other applications like online games not? Am I actually losing connection or am I mistaken? Edit: I'd also like to add that netflix on my PS3 which is directly connected to the same access point will also lose connection. So internet browsers and netflix lose their internet connection while online games continue without an issue.

  • Instant connection to wireless network but delayed internet access on Mediacom with Windows 7

    - by David
    I have Mediacom cable internet and their provided modem/wireless router a Cisco DPC3825. Each of the laptops experiencing the trouble have Windows 7 64-bit. When connecting to the wireless network each computer will take a second or two to connect and then toggle from "no internet access" to "internet access" however, no websites are accessible for about five minutes after connecting. After that, there aren't any problems. It happens on all 3 of the laptops I have available and none of them have problems on any other network. It seems like my phone doesn't have the delay issue when it connects. I've power cycled the modem/router along with a DNS flush. I have some of the DNS servers manually set to Google DNS addresses and one just default. I've contacted and had Mediacom support try all its tricks. They changed the SSID and password along with resetting the thing remotely a handful of times. It was installed just this month and seemed to pass the tech's checks upon installation. Nothing in the settings has been changed, but it's been exhibiting this problem from the get go. This guy seems to be having the same problem, but no solution was posted. http://www.dslreports.com/forum/r27372861-IA-Connection-to-Mediacom-wireless-Modem-no-internet- Help greatly appreciated.

  • Cisco Multi-DMZ firewall

    - by BParker
    I need to find a firewall that will give me 1 LAN port, and 5-7 DMZ ports. I have a requirement to replace some FreeBSD systems that are used to run some testing equipment. It is essential that the DMZ ports cannot communicate with each other, but the LAN port can communicate with everyone. That way a user on the LAN can connect to the test systems, but the test systems are isolated entirely and cannot interfere with each other. One of the DMZ's will be connected to a VMWare ESXi server, one to a standard server, and the rest to various types of equipment. The lan port will be connected to the corporate LAN switch. Sorry if i am a little vague, I am just trying to work all this out myself! Currently we have a FreeBSD configured, but the quad port NIC's are pretty expensive, and the PC itself is old, so i would prefer to replace it with a dedicate piece of kit which can do the same job, but more reliably! These test rigs are used all over the place, and get moved quite often, so i am aiming for Cisco kit for ease of configuration and reliability of the hardware itself. Thanks

  • ash scripting: space-containing variable refuses to be grepped

    - by Luci Sandor
    I am trying to run the script listed at http://talk.maemo.org/showthread.php?t=70866&page=2 on its intended hardware, a Nokia Linux phone running BusyBox ash. The script receives the name of WiFi network as a parameter, and tries to connect the phone to it. I suspect the script works, but my SSID, BU (802.1x), has space and parentheses in it. So when I type at the command prompt autoconnect.sh BU\ \(802.1x\) I get various errors. First, LIST=`iwconfig wlan0 | awk -F":" '/ESSID/{print $2}'` if [ $LIST = "\"$1\"" ]; then ...fails, even I am connected to the network. The error is not avoided by using single or double quotes instead of escaping characters at the command prompt. Second, if [ -z `iwlist wlan0 scan | grep -m 1 -o \"$1\"` ]; then echo SSID \"$1\" not found; shows that grep does not find the string, although the same grep, typed directly into the command prompt, does find 'BU (802.1x)'. How do I quote $1 in the two circumstances above so that it will work with my network SSID, containing spaces and parentheses? Thank you.

  • Xvnc4 started from xinetd only displays empty gray X screen

    - by Scott Thomason
    I'm attempting to setup an Ubuntu 10.10 box so that anyone can connect to port 5900 and be greeted by the gdm login manager. To do so, I added a vnc entry in /etc/services and I am starting Xvnc4 using this xinetd config file: service vnc { protocol = tcp socket_type = stream wait = no user = nobody server = /usr/bin/Xvnc server_args = -geometry 1000x700 -depth 24 -broadcast -inetd -once -securitytypes None } This kind of works...I can start multiple sessions all to port 5900, and I get an X screen. The problem is that I only get an empty, gray X screen with no applications started. I know when you run vncserver from the command line it will look to your ~/.vnc/ directory for your passwd and xstartup files, and I think what I want to do is put "gnome-session" into the xstart file. However, which xstartup file? The running user is "nobody" who obviously doesn't have a ~/.vnc/ directory. I tried a /root/.vnc/xstartup file and a ~scott/.vnc/xstartup file and it doesn't look like they were even read. I changed the xinetd vnc service so that it would "strace" Xvnc4. I looked thru all the "open" lines and didn't get a clue as to what file it was trying to read for xstart. Can anyone help? I just want a terminal server where the user is presented with a gdm login screen.

  • VPN being blocked somewhere between either my BT2700HGV and DLink DFL-210

    - by Dom
    Hi, For some time I have been unable to get VPN working through my set up. I have a BT2700HGV Router (2 Wire Model) and as a firewall I have the Dlink DFL-210. You can't turn the firewall completely off on the BT2700HGV so I have it set to DMZplus mode for the Firewall. In theory this should then allow the VPN ports through. On the Firewall I have a series of rules set up and one is the pptp-allow rule which should allow access on the correct ports also. When I try to connect via VPN however the client machine gets an error 809. If I check the log on the Dlink firewall, I see this record: http://dl.dropbox.com/u/1041315/packetdrop.PNG The laptop I am testing the vpn with is connected directly to the BT2700HGV router and I am trying to VPN from it onto 81.138.86.217. I can't work out whether I have some sort of problem in the set up of the rules on my firewall or if the BT router (even though it's in DMZplus mode) is still blocking port 1723. I read somewhere that there where problems because BTs Openzone held onto this port for some reason. Any help would be greatly appreciated. If you need further screen shots or information then please let me know. I wasn't able to create new tags for the router and firewall name or insert the picture in as I am new to the forum. Dom :-)

  • Copying SD Cards with "LaCie d2 Network"

    - by rjstelling
    The LaCie d2 Network has a feature where by you can attach a USB drive and press the blue button at the from and it will copy the drive contents (no computer required). (See this review for more info). USB 2.0 and eSATA ports are also provided but these are not designed for extending the d2 Network's storage. Rather, they allow you to connect portable drives for uploading their data to the d2 Network directly. The process is quite slick, too: just plug in a drive and press the big blue button on the front of the unit to trigger an immediate upload. This copies over everything on the external device and seems ideal for camera use. Is it possible to use an microSD or SD card adapter (like the Kingston MobileLite 9-in-1) and copy the contents of the card? I'm assuming the card reader just "looks like" a normal USB flash drive the computer or (in this case) LaCie d2 Network. Is this assumption correct? Do you know any reason why this won't work?

  • make local only daemon listening on different interface (using iptables port forwarding)?

    - by UniIsland
    i have a daemon program which listens on 127.0.0.1:8000. i need to access it when i connect to my box with vpn. so i want it to listen on the ppp0 interface too. i've tried the "ssh -L" method. it works, but i don't think it's the right way to do that, having an extra ssh process running in the background. i tried the "netcat" method. it exits when the connection is closed. so not a valid way for "listening". i also tried several iptables rules. none of them worked. i'm not listing here all the rules i've used. iptables -A FORWARD -j ACCEPT iptables -t nat -A PREROUTING -i ppp+ -p tcp --dport 8000 -j DNAT --to-destination 127.0.0.1:8000 the above ruleset doesn't work. i have net.ipv4.ip_forward set to 1. anyone knows how to redirect traffic from ppp interface to lo? say, listen on "192.168.45.1:8000 (ppp0)" as well as "127.0.0.1:8000 (lo)" there's no need to alter the port. thanx

  • FreeNAS AFP Doesn't Authenticate

    - by Timothy R. Butler
    I just set up a FreeNAS 8.0.3 server and am trying to use its AFP (Netatalk) service to access it via a Mac OS X Lion system. I created the ZFS volume, set its permissions to include my user in its owner group (and set group write permissions), created an AFP share with AFP3 and told that share to "allow" @uninet (my group). I have a user on the server named tbutler, matching the user on my Mac. I can see the server, "Beatrice," in Finder. When I try to login in Finder using "Connect As...," the user "tbutler" and the proper password, I am returned to the main Finder window with the black bar now saying "Connection Failed." Here's the most recent data from /var/messages on the server, which shows me trying to login both as a "Registered User" and a "Guest": Jul 30 00:29:07 freenas afpd[8972]: AFP3.3 Login by nobody Jul 30 00:29:08 freenas afpd[8972]: AFP logout by nobody Jul 30 00:29:08 freenas afpd[8972]: dsi_stream_read: len:0, unexpected EOF Jul 30 00:29:08 freenas afpd[8972]: afp_over_dsi: client logged out, terminating DSI session Jul 30 00:29:08 freenas afpd[8972]: AFP statistics: 0.14 KB read, 0.12 KB written Jul 30 00:29:14 freenas afpd[8975]: AFP3.3 Login by tbutler Jul 30 00:29:14 freenas afpd[8975]: AFP logout by tbutler Jul 30 00:29:14 freenas afpd[8975]: dsi_stream_read: len:0, unexpected EOF Jul 30 00:29:14 freenas afpd[8975]: afp_over_dsi: client logged out, terminating DSI session Jul 30 00:29:14 freenas afpd[8975]: AFP statistics: 0.62 KB read, 0.48 KB written Jul 30 00:29:20 freenas afpd[8978]: AFP3.3 Login by tbutler Jul 30 00:29:20 freenas afpd[8978]: AFP logout by tbutler Jul 30 00:29:20 freenas afpd[8978]: dsi_stream_read: len:0, unexpected EOF Jul 30 00:29:20 freenas afpd[8978]: afp_over_dsi: client logged out, terminating DSI session Jul 30 00:29:20 freenas afpd[8978]: AFP statistics: 0.62 KB read, 0.48 KB written Jul 30 00:29:27 freenas afpd[8983]: AFP3.3 Login by nobody (My clock is clearly not properly set, but be that as it may...) Any suggestions? UPDATE: Apparently this problem occurs if one gives the AFP share a password in the AFP share settings box. When I removed the password and tried to login using a user account again, it worked just fine.

  • Exchange 2003 IMAP not working for some users

    - by John Gardeniers
    We normally don't have a need for IMAP connections from outside the company network but in order to allow a one user to use IMAP on a portable device I've turned it on and opened port 993 on the firewall. When the user in question was unable to get connected I tested this using Outlook remotely. Start by creating a new IMAP account in Outlook using a test account. No problems, it worked perfectly. Now try the same thing using the account of the user who actually needs to connect and it's a no-go. Outlook simply keeps prompting for logon credentials. Next I tried using my own account and that too failed. Testing with a couple of other accounts worked perfectly. Interestingly enough, with my own account I've used IMAP on a MAC before (internally) without a problem and I'm not aware of anything that has changed which could affect IMAP on my account. Checking the user settings in ADUC showed that all accounts have the same Exchange protocol settings. Specifically, IMAP is enabled. A check of the event logs on the server reveals no entries for the connection attempts, making this kind of difficult to debug. Has anyone here encountered such a situation and, even more importantly, what caused it?

  • How do I get netcat to accept connections from outside the LAN?

    - by Chris
    I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?
