  • IIS7 - multiple ports for websites, some working, some not.

    - by glasnt
    I have multiple IIS7 websites hanging off 1 IP, using different ports. All three sites use Z.A.B.C:XX, where XX is {100, 200, 300} * There's no web.config settings not making :300 not work, the bindings are set ok. I can even change the ports so 200 becomes 300, but the original 300 still doesn't work. They are all shown by IP, so it's not DNS. There's no SSL setting differences between them. I can't see anything in metabase.xml that would make one behave differently to another. Are there any other settings in IIS7 that I might not be finding, that would fix the issue? * not the real values.

  • Does connecting to the default host via public IP from within its subnet cause any issues?

    - by username
    I'm setting up a small office network with a single public IP (let's say it's 69.16.230.117). I've configured NAT on the router with incoming traffic forwarded to the server (say the server has a private IP of 192.168.0.2). Is it okay to configure the client machines on the same subnet to access the server via the router's public IP (69.16.230.117)? In practice it's never caused me problems, but I've heard, here and there, that it is a bad idea, and one should use the private IP (192.168.0.2). Does connecting to the default host via public IP from within its subnet cause any issues? Please refrain from writing "never! it breaks the intranet!" ;-)

  • Removing DVI connectors stuck in video card ports

    - by thecyclegeek
    I need some help removing a couple of DVI connectors which are stuck in my video card ports. I don't know why they were screwed in so tightly in the first place but they won't move. I need to replace hardware in the machine, but doing so with the cables connected and the box in its current position is nearly impossible. I've tried pliers with grips to loosen the screws holding the cable, and I've tried a screwdriver, the latter ended up breaking off the plastic. Neither worked. I'm at a loss as to what to do and I'm very frustrated. Can I get some suggestions?

  • When I remove the SSL port 443 from IIS my website stops loading, how can I have it just work with only port 80 and no SSL?

    - by shogun
    I am trying to disable SSL, I delete the 443 port so there is only an entry for port 80 and now the site won't load at all. If I re-add the 443 configuration it loads fine. What is causing it to require that? Why can't I set it up to run without SSL? Instead of just failing it should just load the page without HTTPS. If I disable port 443 and then I browse via HTTP, it STILL fails even though I am not trying to use HTTPS. What gives? When/where/how does it decide to use SSL?

  • setting my mysql server - limiting domains that can connect

    - by Alex
    I am trying to setup a mysql server on my machine. I would like to limit the domains that it listens for connections to. My understanding is that you can either have it listen to 1 ip or all ip's. Therefore, if i want to connect remotely I have to say all ips. Then I would like to block all domains but the ones I know should actually be connecting.. I believe this is done through windows firewall. However, how do i do this by domain instead of IP?

  • Does the nginx “upstream” directive have a port setting?

    - by orzzzzz
    moved from:http://stackoverflow.com/questions/3748517/does-nginx-upstream-has-a-port-setting I use upstream and proxy for load balancing. The directive proxy_pass http://upstream_name uses the default port, which is 80. However, if the upstream server does not listen on this port, then the request fails. How do I specify an alternate port? my configuration: http{ #... upstream myups{ server 192.168.1.100:6666; server 192.168.1.101:9999; } #.... server{ listen 81; #..... location ~ /myapp { proxy_pass http://myups:81/; } } nginx -t: [warn]: upstream "myups" may not have port 81 in /opt/nginx/conf/nginx.conf:78.

    - by user160605
    I`m trying to figure out a way to remote into both my servers on the same network. I have a 2008 r2 and a server 2003. Right now i can remote into my server 2003 but I dont know what IP to use for the 2k8 server. They seem to have the same public im. Both servers are behind a fire wall (sonic wall tz170) I rememeber having to to something on the firewall to get into the 2k3 server but forgot what I did... Can anyone give some advice thanks

  • .NET SerialPort DataReceived event not firing

    - by Klay
    I have a WPF test app for evaluating event-based serial port communication (vs. polling the serial port). The problem is that the DataReceived event doesn't seem to be firing at all. I have a very basic WPF form with a TextBox for user input, a TextBlock for output, and a button to write the input to the serial port. Here's the code: public partial class Window1 : Window { SerialPort port; public Window1() { InitializeComponent(); port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); } void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { Debug.Print("receiving!"); string data = port.ReadExisting(); Debug.Print(data); outputText.Text = data; } private void Button_Click(object sender, RoutedEventArgs e) { Debug.Print("sending: " + inputText.Text); port.WriteLine(inputText.Text); } } Now, here are the complicating factors: The laptop I'm working on has no serial ports, so I'm using a piece of software called Virtual Serial Port Emulator to setup a COM2. VSPE has worked admirably in the past, and it's not clear why it would only malfunction with .NET's SerialPort class, but I mention it just in case. When I hit the button on my form to send the data, my Hyperterminal window (connected on COM2) shows that the data is getting through. Yes, I disconnect Hyperterminal when I want to test my form's ability to read the port. I've tried opening the port before wiring up the event. No change. I've read through another post here where someone else is having a similar problem. None of that info has helped me in this case. EDIT: Here's the console version (modified from http://mark.michaelis.net/Blog/TheBasicsOfSystemIOPortsSerialPort.aspx): class Program { static SerialPort port; static void Main(string[] args) { port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); string text; do { text = Console.ReadLine(); port.Write(text + "\r\n"); } while (text.ToLower() != "q"); } public static void port_DataReceived(object sender, SerialDataReceivedEventArgs args) { string text = port.ReadExisting(); Console.WriteLine("received: " + text); } } This should eliminate any concern that it's a Threading issue (I think). This doesn't work either. Again, Hyperterminal reports the data sent through the port, but the console app doesn't seem to fire the DataReceived event. EDIT #2: I realized that I had two separate apps that should both send and receive from the serial port, so I decided to try running them simultaneously... If I type into the console app, the WPF app DataReceived event fires, with the expected threading error (which I know how to deal with). If I type into the WPF app, the console app DataReceived event fires, and it echoes the data. I'm guessing the issue is somewhere in my use of the VSPE software, which is set up to treat one serial port as both input and output. And through some weirdness of the SerialPort class, one instance of a serial port can't be both the sender and receiver. Anyway, I think it's solved.

  • Postfix to deliver mail to a virtual address mailbox

    - by Chloe
    Postfix version 2.6.6, Dovecot Version 2.0.9 I want to setup Postfix + Dovecot. Dovecot seems to be working. I can authenticate. However, the mailbox is empty! Nothing will get delivered! I followed many tutorials on Postfix + Dovecot but they seem to want to complicate things by using Dovecot LDA or MySQL. I just want it to be very simple and having Postfix deliver to the virtual mail boxes are fine. I don't need MySQL either. I already set up a custom password file that Dovecot uses for authentication and I can login to POP3 with SSL. I can see from the logs that Postfix is delivering to the system user accounts (the catch-all), instead of the virtual users that I set up in Dovecot. The SMTP + SSL authentication seems to work also. I can also see from the logs that Dovecot is checking the correct virtual mail folder. I just need to figure out how to get Postfix to deliver to the virtual mail boxes. I have the following which I believe are relevant. Let me know what other settings you need to see: alias_maps = hash:/etc/aliases mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = xxx.com myhostname = mail.xxx.com mynetworks = 99.99.99.99, 99.99.99.99 myorigin = $mydomain relay_domains = $mydestination, xxx.com, domain2.net, domain3.com sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_recipient_restrictions = reject_non_fqdn_sender reject_non_fqdn_recipient reject_unknown_recipient_domain permit_sasl_authenticated check_relay_domains smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_sender_restrictions = check_sender_mx_access cidr:/etc/postfix/bogus_mx reject_invalid_hostname reject_unknown_sender_domain reject_non_fqdn_sender virtual_mailbox_base = /var/spool/vmail virtual_mailbox_domains = xxx.com, domain2.net, domain3.com virtual_minimum_uid = 444 Postfix master.cf: submission inet n - - - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_sasl_security_options=noanonymous -o smtpd_sasl_local_domain=$myhostname -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_sender_login_maps=hash:/etc/postfix/virtual -o smtpd_sender_restrictions=reject_sender_login_mismatch -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject Dovecot related: mail_location = maildir:~/Maildir passdb { args = /etc/dovecot/users.conf driver = passwd-file } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 user = postfix } } The virtual mail user: vmail:x:444:99:virtual mail users:/var/spool/vmail:/sbin/nologin Here is the /var/log/maillog when I try to send something to myself: Oct 25 22:10:05 308321 postfix/smtpd[2200]: connect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:05 308321 postfix/smtpd[2200]: D224BD4753: client=user-999.cable.mindspring.com[99.99.99.99], sasl_method=LOGIN, [email protected] Oct 25 22:10:06 308321 postfix/cleanup[2207]: D224BD4753: message-id=<7DC3C163CFFC483AB6226F8D3D9969D2@dumbopc> Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: from=<[email protected]>, size=1385, nrcpt=1 (queue active) Oct 25 22:10:06 308321 postfix/smtpd[2200]: disconnect from user-999.cable.mindspring.com[99.99.99.99] Oct 25 22:10:06 308321 postfix/local[2208]: D224BD4753: to=<[email protected]>, orig_to=<[email protected]>, relay=local, delay=1.1, delays=0.53/0.02/0/0.51, dsn=2.0.0, status=sent (delivered to mailbox) Oct 25 22:10:06 308321 postfix/qmgr[2168]: D224BD4753: removed

  • Why isn't passwordless ssh working?

    - by Nelson
    I have two Ubuntu Server machines sitting at home. One is 192.168.1.15 (we'll call this 15), and the other is 192.168.1.25 (we'll call this 25). For some reason, when I want to setup passwordless login from 15 to 25, it works like a champ. When I repeat the steps on 25, so that 25 can login without a password on 15, no dice. I have checked both sshd_config files. Both have: RSAAuthentication yes PubkeyAuthentication yes I have checked permissions on both servers: drwx------ 2 bion2 bion2 4096 Dec 4 12:51 .ssh -rw------- 1 bion2 bion2 398 Dec 4 13:10 authorized_keys On 25. drwx------ 2 shimdidly shimdidly 4096 Dec 4 19:15 .ssh -rw------- 1 shimdidly shimdidly 1018 Dec 4 18:54 authorized_keys On 15. I just don't understand when things would work one way and not the other. I know it's probably something obvious just staring me in the face, but for the life of me, I can't figure out what is going on. Here's what ssh -v says when I try to ssh from 25 to 15: ssh -v -p 51337 192.168.1.15 OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 192.168.1.15 [192.168.1.15] port 51337. debug1: Connection established. debug1: identity file /home/shimdidly/.ssh/id_rsa type 1 debug1: Checking blacklist file /usr/share/ssh/blacklist.RSA-2048 debug1: Checking blacklist file /etc/ssh/blacklist.RSA-2048 debug1: identity file /home/shimdidly/.ssh/id_rsa-cert type -1 debug1: identity file /home/shimdidly/.ssh/id_dsa type 2 debug1: Checking blacklist file /usr/share/ssh/blacklist.DSA-1024 debug1: Checking blacklist file /etc/ssh/blacklist.DSA-1024 debug1: identity file /home/shimdidly/.ssh/id_dsa-cert type -1 debug1: identity file /home/shimdidly/.ssh/id_ecdsa type -1 debug1: identity file /home/shimdidly/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.9p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9p1 Debian-5ubuntu1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 54:5c:60:80:74:ab:ab:31:36:a1:d3:9b:db:31:2a:ee debug1: Host '[192.168.1.15]:51337' is known and matches the ECDSA host key. debug1: Found key in /home/shimdidly/.ssh/known_hosts:2 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/shimdidly/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Offering DSA public key: /home/shimdidly/.ssh/id_dsa debug1: Authentications that can continue: publickey,password debug1: Trying private key: /home/shimdidly/.ssh/id_ecdsa debug1: Next authentication method: password

  • Need help accessing PHP DOM elements

    - by Michael Pasqualone
    Hey guys, I have the following HTML structure that I am trying to pull information from: // Product 1 <div class="productName"> <span id="product-name-1">Product Name 1</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse 1, ACT</span> <span class="quantityInStock">25</span> </div> // Product 2 <div class="productName"> <span id="product-name-2">Product Name 2</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse 2, ACT</span> <span class="quantityInStock">25</span> </div> … // Product X <div class="productName"> <span id="product-name-X">Product Name X</span> </div> <div class="productDetail"> <span class="warehouse">Warehouse X, ACT</span> <span class="quantityInStock">25</span> </div> I don't have control of the source html and as you'll see productName and it's accompanying productDetail are not contained within a common element. Now, I am using the following php code to try and parse the page. $html = new DOMDocument(); $html->loadHtmlFile('product_test.html'); $xPath = new DOMXPath($html); $domQuery = '//div[@class="productName"]|//div[@class="productDetail"]'; $entries = $xPath->query($domQuery); foreach ($entries as $entry) { echo "Detail: " . $entry->nodeValue) . "<br />\n"; } Which prints the following: Detail: Product Name 1 Detail: Warehouse 1, ACT Detail: 25 Detail: Product Name 2 Detail: Warehouse 2, ACT Detail: 25 Detail: Product Name X Detail: Warehouse X, ACT Detail: 25 Now, this is close to what I want. But I need to do some processing on each Product, Warehouse and Quantity stock and can't figure out how to parse it out into separate product groups. The final output I am after is something like: Product 1: Name: Product Name 1 Warehouse: Warehouse 1, ACT Stock: 25 Product 2: Name: Product Name 2 Warehouse: Warehouse 2, ACT Stock: 25 I can't just figure it out, and I can't wrap my head around this DOM stuff as the elements don't quite work the same as a standard array. If anyone can assist, or point me in the right direction I will be ever appreciative.

  • VS 2008 debugger: How does it decide what Cassini port to run a web service under?

    - by BDW
    I have a VS 2008 solution that includes a web site and a web service. I'm developing both at once, and it's helpful to be able to debug from one into the other. It occasionally can't find the web service. If I look in the web.config, I find the port number it's looking at is not the port number it auto-runs the service in when I use the debugger. For example, the web.config reference says something like: add key="mynamespace.mywebservice" value="http://localhost:55765/mywebservice.asmx" When I hover over the Cassini port icon, I find that the web service is running in port 55382 (or some other non-55765 port). No wonder it can't find it. Is there a way to enforce that the port number it runs under is the one specified in the web config? And if it's not using the web config port number to figure out where to run it... where does it decide? I know in VS2005, there was a way to specify the port number to use when debugging, but I can't find that anywhere in the web service project in VS 2008. This is really going to cause problems as more developers come on to this project - how can I fix it? Deleting and re-adding the web services to the project fixes it, but I'd literally have to do it a couple times a day, not an ideal solution.

  • How can I close a port that appears to be orphaned by Xvfb?

    - by Jim Fiorato
    I'm running Xvfb on a FC8 Amazon EC2 image. On occasion Xvfb will crash (unable at the moment to find out the reason for the crash), and after crashing the TCP port will appear to be orphaned. I'm unable to get a PID to kill any process that may be using it. I'm starting Xvfb with: Xvfb :7 -screen 0 1024x768x24 & Examples of what I'm working with are below, the Xvfb port is (was) 6007: # netstat -ap Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:ssh *:* LISTEN 1894/sshd tcp 0 0 *:6007 *:* LISTEN - tcp 0 352 ip-10-84-69-165.ec2.int:ssh c-71-194-253-238.hsd1:51689 ESTABLISHED 2981/0 udp 0 0 *:bootpc *:* 1817/dhclient udp 0 0 *:bootpc *:* 1463/dhclient Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node PID/Program name Path unix 2 [ ] DGRAM 871 668/udevd @/org/kernel/udev/udevd unix 2 [ ACC ] STREAM LISTENING 5385 1880/dbus-daemon /var/run/dbus/system_bus_socket unix 6 [ ] DGRAM 5353 1867/rsyslogd /dev/log unix 2 [ ] DGRAM 11861 2981/0 unix 2 [ ] DGRAM 5461 1974/crond unix 2 [ ] DGRAM 5451 1904/console-kit-da unix 3 [ ] STREAM CONNECTED 5438 1880/dbus-daemon /var/run/dbus/system_bus_socket unix 3 [ ] STREAM CONNECTED 5437 1904/console-kit-da unix 3 [ ] STREAM CONNECTED 5396 1880/dbus-daemon unix 3 [ ] STREAM CONNECTED 5395 1880/dbus-daemon unix 2 [ ] DGRAM 5361 1871/rklogd # lsof -i COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME dhclient 1463 root 3u IPv4 4704 UDP *:bootpc dhclient 1817 root 4u IPv4 5173 UDP *:bootpc sshd 1894 root 3u IPv4 5414 TCP *:ssh (LISTEN) sshd 2981 root 3u IPv4 11825 TCP ip-10-84-69-165.ec2.internal:ssh->c-71-194-253-238.hsd1.il.comcast.net:51689 (ESTABLISHED) Attempting to force the port closed with iptables doesn't seem to work either. iptables -A INPUT -p tcp --dport 6007 -j DROP I'm at a loss as to how to reclaim/free the port. From what I can tell, this port will remain in this state until the EC2 instance is shut down. So, how can I close this port so I can restart Xvfb?

  • Non ASCII char in PHP?

    - by domagoj412
    Hello, I am trying to send something to serial port (r232) with PHP. I am using this class: http://www.phpclasses.org/browse/package/3679.html The problem is that I am allowed to send only 1 byte. But if I send something like "1", I am actually sending 49 (ASCII for 1). Instead of send("1"), I tried with send(1) but it is no good, because this is integer which has 2 bytes. So is there a way to send a "real" char, not ASCII equivalent?

  • Java Port Socket Programming Error

    - by atrus-darkstone
    Hi- I have been working on a java client-server program using port sockets. The goal of this program is for the client to take a screenshot of the machine it is running on, break the RGB info of this image down into integers and arrays, then send this info over to the server, where it is reconstructed into a new image file. However, when I run the program I am experiencing the following two bugs: The first number recieved by the server, no matter what its value is according to the client, is always 49. The client only sends(or the server only receives?) the first value, then the program hangs forever. Any ideas as to why this is happening, and what I can do to fix it? The code for both client and server is below. Thanks!

  • Reverse SSH tunnel: how can I send my port number to the server?

    - by Tom
    I have two machines, Client and Server. Client (who is behind a corporate firewall) opens a reverse SSH tunnel to Server, which has a publicly-accessible IP address, using this command: ssh -nNT -R0:localhost:2222 [email protected] In OpenSSH 5.3+, the 0 occurring just after the -R means "pick an available port" rather than explicitly calling for one. The reason I'm doing this is because I don't want to pick a port that's already in use. In truth, there are actually many Clients out there that need to set up similar tunnels. The problem at this point is that the server does not know which Client is which. If we want to connect back to one of these Clients (via localhost) then how do we know which port refers to which client? I'm aware that ssh reports the port number to the command line when used in the above manner. However, I'd also like to use autossh to keep the sessions alive. autossh runs its child process via fork/exec, presumably, so that the output of the actual ssh command is lost in the ether. Furthermore, I can't think of any other way to get the remote port from Client. Thus, I'm wondering if there is a way to determine this port on Server. One idea I have is to somehow use /etc/sshrc, which is supposedly a script that runs for every connection. However, I don't know how one would get the pertinent information here (perhaps the PID of the particular sshd process handling that connection?) I'd love some pointers. Thanks!
