  • Server IP must be a LAN IP (Port Forwarding Netgear Router)? [closed]

    - by rphello101
    I'm trying to set up a server (Apache) on my computer (fairly new to it). As I understand it, for it to be accessible to other computers, I need to forward port 80. When I try to forward the port though, I get the error: Server IP must be a LAN IP. I noticed in ipconfig that my default gateway is different than my wireless router. My computer is not hardwired, not on WiFi. Furthermore, I do not, at this point, have a static IP. I read that it should still work with a dynamic IP until it changes. Any ideas on what I can do? I'm using Windows 7 in case it matters.

  • How I can fix this code to allow my AVR to talk over serial port?

    - by samoz
    Hi guys, I've been pulling my hair out lately trying to get an ATmega162 on my STK200 to talk to my computer over RS232. I checked and made sure that the STK200 contains a MAX202CPE chip. I've configured the chip to use its internal 8MHz clock and divided it by 8. I've tried to copy the code out of the data sheet (and made changes where the compiler complained), but to no avail. My code is below, could someone please help me fix the problems that I'm having? I've confirmed that my serial port works on other devices and is not faulty. Thanks! #include <avr/io.h> #include <avr/iom162.h> #define BAUDRATE 4800 void USART_Init(unsigned int baud) { UBRR0H = (unsigned char)(baud >> 8); UBRR0L = (unsigned char)baud; UCSR0B = (1 << RXEN0) | (1 << TXEN0); UCSR0C = (1 << URSEL0) | (1 << USBS0) | (3 << UCSZ00); } void USART_Transmit(unsigned char data) { while(!(UCSR0A & (1 << UDRE0))); UDR0 = data; } unsigned char USART_Receive() { while(!(UCSR0A & (1 << RXC0))); return UDR0; } int main() { USART_Init(BAUDRATE); unsigned char data; // all are 1, all as output DDRB = 0xFF; while(1) { data = USART_Receive(); PORTB = data; USART_Transmit(data); } }

  • Port listening on localhost:8000 but not on ip:8000

    - by Marionette
    Hello I'm running a web application on port 8000. When I access it from the host server localhost:8000 it responds ok, 127.0.0.1:8000 also works, but 192.168.1.7:8000 does not work. 192.168.1.7 is the ip of my server. Also if i try to go to another web application running on port 80 it works 192.168.1.7 I enabled ufw firewall and set ufw default allow. I am using ubuntu server 12.04 Any suggestions on why I can't get to my app on port 8000 using the ip-address:8000? Thanks in advance!

  • HDMI port not recognized on Sony Vaio

    - by julio
    I am running Ubuntu 11.10 64bit with a Sony VAIO VPC F11. It has an NVIDIA GeForce 310M video card, with the latest Nvidia drivers for the 64 bit linux, and a Windows partition with Win7 64bit. NVIDIA driver version is NVIDIA-Linux-x86_64-280.13 External monitor is Samsung SyncMaster P2770 If I boot into the Windows partition, the HDMI works as expected, with sound and video-- under linux, the HDMI port is not recognized at all, apparently, and provides no signal to the attached monitor. The nividia-settings tool does not recognize any monitor connected to the HDMI port. Disper is installed and cannot recognize an attached external monitor. Can anyone help me diagnose this issue and fix it if possible? The laptop has only the one HDMI port to connect any external monitor, so it I can't get this working I'm stuck using either the laptop screen or Windows. Thanks

  • Connecting to VPN / proxy with different port number

    - by user779159
    I have an IP address, port, username, and password for one of those VPN / proxy services that allows you to use an IP address other than what your ISP gives you, but in the 'Edit Connections VPN' GUI I don't see where to enter a port. I enter the IP address under 'Gateway' and the username and password where it asks for it, but it doesn't work. I try to enter it with the IP address ending with a colon, followed by the port, but that doesn't work either (e.g. "1.1.1.1:9999"). Any idea how I could make it work? I'm using Ubuntu 12.04 LTS. Thanks.

  • Re-Route Mail to a port other than 25

    - by Ken
    Is there a way to route mail to another port? I have an email account attached to my laptop that I'd like to be able to send and receive mail from. Due to mobility, I'll be passing through various networks that will probably block this port. My dynamic DNS provider allows me to utilize web-forwards for MX domains; is this possible? where I can web forward to a domain:port which is managed by my DNS provider when I traverse between networks. If not, is there a way? Of course i could use web-mail or relay-forwarding from my home server, but that's not geeky enough.

  • SSH refusing connection after changing default port

    - by wm90
    currently I'm handling 2 server (A and B). In server A I installed Ubuntu 12.10. I changed the SSH port into 1198 and it works fine. In server B it has been installed with Ubuntu 11.04. I tried to change the port number into 1198 as well but it refused the connection when I tried to connect again using Putty. I change the SSH configuration on /etc/ssh/sshd_config and I did restart the SSH using sudo service ssh restart. I was thinking its because of firewall allowed port but the firewall shows inactive when I run sudo ufw status. Any idea why this can happened?

  • Change gui port(8080) utorrent

    - by user87073
    I'm fresh on Ubuntu, still learning how to use it. Recently I've been trying to install utorrent, which I already was able to do so, but I need the port 8080 free to use run tomcat/glassfish and on port 80 php. Briefly, how can I change utorrent port from 8080 to another one? I've been trying to find a solution for this issue for about 3 days now, I saw some solutions, such as create a utserver.config, but I have no clue in how to use it or config it by terminal or on properties, that is something hardly explained by anyone. Any help will be appreciated :D.

  • Comcast SMC Port Forwarding Issue

    - by Zach Fedora
    I have a Comcast SMCD3G modem/router and I've been having issues getting the port to forward - When I check an online "open-port-checker" it says the port is forwarded/they can see the port on my IP. (1 Static IP is assigned to the modem) But when I try to access port 80 for example on a browser, it times out. Also when I try to remote desktop to the server (Windows Server 2008 R2) it doesn't work, yet canyouseeme.org says it is open. Any ideas as to what the problem could be?

  • C# Detect Localhost Port Usage

    - by ThaKidd
    In advance, thank you for your advice. I am currently working on a program which uses Putty to create a SSH connection with a server that uses local port forwarding to enable a client, running my software, to access the service behind the SSH server via localhost. IE: client:20100 - Internet - Remote SSH server exposed via router/firewall - Local Intranet - Intranet Web POP3 Server:110. Cmd Line: "putty -ssh -2 -P 22 -C -L 20100:intranteIP:110 -pw sshpassword sshusername@sshserver" Client would use putty to create a SSH connection with the SSH server specifying in the connection string that it would like to tie port 110 of the Intranet POP3 Server to port 20100 on the client system. Therefore the client would be able to open up a mail client to localhost:20100 and interact with the Internal POP3 server over the SSH tunnel. The above is a general description. I already know what I am trying to do will work without a problem so am not looking for debate on the above. The question is this...How can I ensure the local port (I cannot use dynamic ports, so it must be static) on localhost is not being used or listened to by any other application? I am currently executing this code in my C# app: private bool checkPort(int port) { try { //Create a socket on the current IPv4 address Socket TestSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); // Create an IP end point IPEndPoint localIP = new IPEndPoint(IPAddress.Parse("127.0.0.1"), port); // Bind that port TestSocket.Bind(localIP); // Cleanup TestSocket.Close(); return false; } catch (Exception e) { // Exception occurred. Port is already bound. return true; } } I am currently calling this function starting with a specific port in a for loop to get the 'false' return at the first available port. The first port I try is actually being listened to by uTorrent. The above code does not catch this and my connection fails. What is the best method to ensure a port is truly free? I do understand some other program may grab the port during/after I have tested it. I just need to find something that will ensure it is not currently in use AT ALL when the test is executed. If there is a way to truly reserve the localhost port during the test, I would love to hear about it.

  • Should we increase local port range limit on busy memcached servers

    - by Majid Azimi
    nixcraft has a tutorial on configuring memcached server(link) at the end says: For busy memcached server you need to increase system file descriptor and IP port limits here is the code to do so: # Increase system IP port limits net.ipv4.ip_local_port_range = 2000 65000 why should we do this? memcached is a server and it will respond to clients with its listening port which is 11211 by default. So we shouldn't be limited by local port range.(net.ipv4.ip_local_port_range) The only limit is file descriptors. local port range should be a limit for servers like squid which generate local traffic

  • Windows Server 2008 and port 80

    - by Frank
    Hi experts, I'm having an issue with my Windows Server 2008. I can successfuly connect to it with FTP(port 21), remote desktop(whatever the port number is), https but not with simple http or port 80, from the outside of my LAN. Is there some settings I don't know about regarding this special port on the firewall or on IIS7? For your information, I can connect to port 80 as long as I'm on the same LAN, but as soon as the request come from the outside, I get nothing... Please help Thank you

  • Looking for a small, portable, port-mirroring ethernet switch.

    - by user37244
    I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

  • Using open2300 with Ubuntu

    - by Gawain
    Hello, I am currently running Ubuntu 8.10 and have been trying to use Open2300 to read data from a Lacrosse WS-2310 weather station and report it to the WUnderground server. The program compiles fine but when I try to run it, it does one of two things: usually it pauses for about 4 minutes, then prints "could not reset" to the screen. But sometimes it just hangs forever. It seems like my computer is unable to communicate with the weather station. I have set the serial port as /dev/ttyS0 in the open2300.conf file and i have also tried /dev/ttyS1, /dev/ttyS2, etc with the same result. As far as I can tell, there are no other settings regarding how Open2300 communicates with the device. Is my serial port locked somehow? It could be something as simple as an incorrect configuration for my serial port or something, but I would have no idea how to check that or change the configuration. Any help would be greatly appreciated. thanks, Gawain EDIT: I tried some tests that i found online and everything seems to be working with my serial port... gawain@gawain:~$ ls -l /dev/ttyS* crw-rw---- 1 root dialout 4, 64 2009-07-09 10:01 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 2009-07-09 08:56 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 2009-07-09 08:56 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 2009-07-09 08:56 /dev/ttyS3 gawain@gawain:~$ setserial -a /dev/ttyS0 /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test gawain@gawain:~$ setserial -g /dev/ttyS* /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 8250, Port: 0xd028, IRQ: 18 /dev/ttyS2, UART: 8250, Port: 0xd040, IRQ: 18 /dev/ttyS3, UART: 8250, Port: 0xd050, IRQ: 18 gawain@gawain:~$ echo 12345 > /dev/ttyS0 gawain@gawain:~$ dmesg | tail -3 [ 144.424259] ppdev0: unregistered pardevice [ 145.692199] ppdev0: registered pardevice [ 145.740052] ppdev0: unregistered pardevice I also tried changing the serial port name to /dev/ttys0 (with a lowercase S) and in that case it gave me a different error, "Unable to open serial device." This suggests to me that it is able to open /dev/ttyS0 but something else is preventing it from reading the weather station. Any ideas? thanks.

  • JDBC connections: How to specify the port for data-transfer?

    - by LeO
    I wanto to run my JDBC-connection (either Oracle or MSSQL) through a proxy-server. Reason for this is to have additional controls of the traffic, especially for developing. I know, I could specify the proxy, which runs on my machine, and the port in the connection-string. But the specified connection-settings are only taken as some kind of handshake to agree on which port the data is finally transferred. And this is defenitly not the port which I have under proxy-control. So, does anybody have an idea, how to specify the port for the data-transfer? I would prefer if this could be done in the connection-string. The same issue applies for Oracle and MSSQL. Thx LeO

  • Where has my parallel port gone? ioperm(888,1,1) returns -1.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • subdomain .htaccess redirection via ssh remote port forwarding

    - by Achim
    I ask you to help me URL redirecting a subdomain to a SSH remote forwarded port: The current setup is the following: The server A have a local webserver running on port 80. This server is connected to a DSL line or a GPRS connection where the IP address changes often. To prevent a DynDNS setup we established a SSH remote port forwarding to a server B with a static IP adress. This is done on server A by the following statement: ssh -N -p 80 -g -R 10000:localhost:80 tunneling@<Server B IP> So by accessing the new port 10000 of the servers B IP-adress, all traffic is forwarded to the server A port 80 - this works fine! But to offer a more comfortable url to the user I want to hide the server B IP-adress and offer a subdomain. My domain provider allows to add subdomains and redirections to some other servers. In general, this works, I've tested this with different servers. But it don't work if the destination is the port forwarded port of server B. The initial redirection is done, the request is send to server A and the response are forwarded to server B and shown in the browser - fine. But then the URL within the browser is switched away from the subdomain to the IP:port of server B. So the user don't see the subdomain in the URL string of the browser anymore. I've tried this with my providers subdomain redirection, as well as .htaccess redirect, as well as META refresh, the problem always persist. Is there a parameter in the ssh reverse forwarding setup (I guess this is the place where the fix have to be) to keep the typed in subdomain URL and not show the IP. Thanks Achim

  • I want to establish a TCP/IP connection over a UART connection (Windows XP/7)

    - by michael
    I want to connect two computer via serial but for each to see each other via a TCP/IP connection. Ie, create new ethernet ports on the computers that are in actual fact serial ports. The reason for this is that I am actually testing the medium in which the serial connection is made (wireless), and part of the experiment will be to use TCP/IP. Preferably I would use something that I can configure (max packet size and setting serial delimiters).
