• Is a "Soft Modem" (i.e. internal) really going to cause incompatibilities?

  - by Farseeker

  Thanks to the fact that our banking industry in Australia... outdated (which is the politest word I could think of when describing the banking industry)... to do a certain kind of transaction our bank requires us to use a dialup modem and send serial data to them. When reading through their documentation (last update: 1995), they state that any "Soft Modems" (by which I assume they mean internal modems, as they refer to a AMR socket on a motherboard, which I haven't seen in donkeys years) should not be used because of "possible incompatibilities" Seeing as buying an external, serial-port modem is actually quite expensive these days and I have a whole box of PCI modems taken out of a bunch of Dells I really don't want to have to buy an external modem. Additionally I think their documentation is simply outdated. Has anyone had experience with internal modems causing issues, where an external modem didn't?

• 2x ATI FireMV 2250 not working

  - by Brett Rigby

  I've just bought 2x ATI FireMV 2250 cards from a reputable seller on ebay... one is a PCI-E x1 and the other is a PCI-E x16. Problem is, neither works in my Dell Vostro 220 PC... Both cards appear to not work. Is there something I'm missing? The seller used an anti-static bag for one of the cards, syaing that: "You Must connect this graphics board to the computer's power supply" but there's no socket for that, nor any indication. I have contacted the seller, but thought I'd raise it here, as it seems strange that two cards can be non-functioning.

• SQL server could not connect: Lacked Sufficient Buffer Space...

  - by chumad

  I recently moved my app to a new server - the app is written in c# against the 3.5 framework. The hardware is faster but the OS is the same (Win Server 2003). No new software is running. On the prior hardware the app would run for months with no problems. Now, in this new install, I get the following error after about 3 days, and the only way to fix it is to reboot: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.) I have yet to find a service I can even shut down to make it work. Anyone had this before and know a solution?

• Hardware question re Hauppauge WinTV-HVR 900 HD video/tv capture unit used with laptop with HDMI output laptop HDMI connection

  - by Bill

  I've ordered a Hauppauge WinTV-HVR 900 HD video/tv capture unit. It is mainly for use with my HP desktop running Windows 7 Professional, but I will want to use it occasionally with my partner's HP laptop running Vista Home Premium. The latter has an HDMI output which works perfectly with my LG 42" LCD TV, enabling display of BBC iPlayer and other catchup services. Will the live or recorded HD signal from the WinTV-HVR 900 HD connected to the laptop's USB input be output on the laptop's HDMI socket as HD? Come to that, will SD content be output? The reason I ask is that I had a problem with a Pinnacle unit which displayed OK on the laptop's screen but not on the TV screen (which did display all the normal Windows material). I've tried the Hauppage website, but it doesn't even acknowledge the existence of the WinTV-HVR 900 HD!

• Firewall blocks FTP PASV response

  - by harper

  I have an FTP server that supports passive server mode (using PASV command). This works fine with Windows XP. When I want to access this server from Windows Vista or Windows 7 with firewall enabled I experience an immediate connection shutdown. A reset packet is sent to the server, and the socket is signaled that the server has reset the connection (which is not true). The problem disappears when the firewall is disabled. Connections to other FTP servers work correctly. The difference is that the server's response to PASV does not enclose the address field with parentheses. This is legal as documented in RFC-959 and RFC-1132. How can I configure the firewall to stop this bad behavior?

• Connect to my virtualbox mysql server

  - by WebweaverD

  I wonder if someone here could help me, this is my set up: I am on a windows 7 machine running a ubuntu virtualbox as my local web server and database server (mysql). I have just got hold of a copy of Komodo which i am running on my windows machine which I would like to hook up to my database. The fields it needs are hostname, port, socket, username and password. I know the username/password but am unsure how to find out what to put for the other fields. The ubuntu vb has an ip of 192.168.0.10, which is in my hosts file as http://swishprint.dev I hope I have asked this in the right place, any help much appreciated.

• netgear GS108TV2 RSTP configuration

  - by jhowland

  I have a large set of GS108TV2 units--my goal is to set up a network which is comprised of several loops for redundancy/fault tolerance. I have a minimal 3 switch loop configured, with RSTP enabled on two ports on each switch. I have my bridge max age set to 6, and my bridge forward delay set to 4, which are the minimum values allowed. Hello time is fixed at 2 seconds. The switches respond to a cable being removed from a socket, but it takes too long. I cannot get the switch to respond to a loss of connection on one of the redundant ports in less than 20 seconds. Is there any way to configure these switches to respond faster than 20 seconds? That is unacceptable for my application. thanks in advance for any help

• Poor TCP loopback throughput on Windows

  - by Yodan Tauber

  I measured the throughput of a locally bound TCP socket connection on my computer (Intel Q9550, 64 GB RAM, Windows XP 64 bit) using iperf. I got dissatisfying results (around 1.6 Gbit/s) each time, no matter how I tweaked the TCP settings (buffer length, window size, max segment size, no delay). I got similar results when I tried netperf. Now, I understand (from sources like these) that the average throughput of a loopback connection should be around 5 Gbit/s. What could be the reasons for such poor performance?

• Firewall blocks outgoing email

  - by Martin Trigaux

  On my Debian server running a Django website, I have an error when I need to send an email. The error received is Exception Type: gaierror Exception Value: [Errno -2] Name or service not known Exception Location: /usr/lib/python2.6/socket.py in create_connection, line 547 You can see the full error log here. After testing, it seems it is my firewall that blocks the request. You can see my iptable file (/etc/init.d/firewall). I think the problem comes from the two commented lines that were supposed to accepts all established connections. When I uncomment them, I have an error iptables: No chain/target/match by that name. Thank you

• Cannot send email from EC2 instance on port 587

  - by Tahsin Mostafiz

  I have written a mail service for our flask application that uses Celery and RabbitMQ to send emails (using gmail). I have got the celery consumer and producer communicating okay but I cannot get to send send emails. I am getting a socket.error: [Errno 101] Network is unreachable. I think this means that AWS is blocking port 587 - even though in my security group I opened both ports 587 and 25 (inbound and outbound). Any reason why this is happening? Any help will be highly appreciated.

• mysql does not start properly

  - by Erik Svenson

  Hi I am using XAMPP on Windows XP. Since I changed the version from 1.73 to 1.77 MySQL does not start properly. That means that the status says, it is started, but the safety check says it is not .

• Starting Apache through XAMPP is not working

  - by nogamo

  I've checked the error logs for this particular problem and it seems no access can be made to port 80. (OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address [::]:80 Turning the Windows firewall off didn't work, so I'm a bit lost. All of this is running on my laptop so I don't have my own "server" per se but I was under the impression that this would work without the need for one independent of my own personal computer. How would I solve this?

• redirecting HTTPS requests to http in lighttpd

  - by chochim

  I have a lighttpd server running which has an SSL certificate installed. I would, due to certain reasons, like to forward all https: //www. requests to http: //www.

Another thing, what is the difference between %1 and $1 ?

• Memcached clustered alternative

  - by Johan Kooijman

  I'm looking to replace memcached. We have a LOT of traffic to our central memcached node which I'd like to split. There's only so much trunking networks I can do. My general idea is to install a memcached-type daemon on every webserver and have the daemons replicate set/delete/updates over all the daemons, so that each webserver connects to a socket or on localhost. All data should be available on all nodes. The alternatives: - repcached (max 2 masters) - redis (single master) - couchdb/mongodb/handlersocket - persistent data on disk, I'd like to remove the disk part to gain more performance. Any hints?

• What alternative is there to Nginx that supports http keep-alive between backends ?

  - by felace

  Hi. I recently asked a question about how to keep a backend connection persistent using Nginx, but found out it wasn't possible anyway, It is an HTTP/1.0 proxy without the ability for keep-alive requests yet. (As a result, backend connections are created and destroyed on every request.) It works all fine right now (since the connection between client and Nginx is kept alive and the result is simply the same), but I don't want to establish a new connection every single time a new request is received ,even if it's on a unix domain socket. So, what software (preferably open-source and not too tedious to configure) do you recommend to accomplish that such connections ?

• How can I set clean urls (enable rewrite) if I don't have a domain ?

  - by Patrick

  In order to enable clean urls in Drupal, I add the lines below to the lighttpd configuration file. However I'm now working on a local server and I don't have a domain available. So I need to work with this address http://local.ip/Sites/mywebsite I've tried to replace ["host"] with ["socket"] and replace the domain with ip and subfolders (see address above), but unsuccessfully. How can I set the configuration file to set clean urls even if I don't have a domain ? thanks $HTTP["host"] =~ "(^|\.)mywebsite\.com" { server.document-root = "/var/www/sites/mywebsite" server.errorlog = "/var/log/lighttpd/mywebsite/error.log" server.name = "mywebsite.com" accesslog.filename = "/var/log/lighttpd/mywebsite/access.log" include_shell "./drupal-lua-conf.sh mywebsite.com" url.access-deny += ( "~", ".inc", ".engine", ".install", ".info", ".module", ".sh", "sql", ".theme", ".tpl.php", ".xtmpl", "Entries", "Repository", "Root" ) # "Fix" for Drupal SA-2006-006, requires lighttpd 1.4.13 or above # Only serve .php files of the drupal base directory $HTTP["url"] =~ "^/.*/.*\.php$" { fastcgi.server = () url.access-deny = ("") } magnet.attract-physical-path-to = ("/etc/lighttpd/drupal-lua-scripts/p-.lua") }

• Restarting nginx backends without losing requests

  - by Oli

  I'm sure it's been asked before in different words but I run several Django sites via uwsgi (emporer mode) behind nginx. It's all a fairly standard configuration but I find that if I restart the central uwsgi process, nginx just bombs out 502s rather than waiting for the socket to become available. I recognise that most of this is probably for a reason but people seeing 502 errors really stings me. It's certainly not something I want a client to see. So... Can I beg nginx to wait/retry backends? Or, Is there anything (other than the obvious) I can do to minimise commercial damage from uwsgi restarts?

• Can I wake up PC/laptop on remote printing request?

  - by dzieciou

  I have an old Epson printer that does not have network adapter, only a USB socket. I have also a computer with network card. I could combine them to put this printer in my local network, but then I would need to keep the computer always up and running. That's definitely not economic. Is there a way to wake up computer when printing request arrives? Something like Wake-on-LAN? Or I am forced to use additional hardware?

• MaxConnections: is it a Client or Request count?

  - by ctacke

  IIS allows me to set a MaxConnections value in the configuration. What is unclear (to me anyway) is what that number means exactly, and I can't find a definitive documented answer. Is this the maximum number of clients that connect simultaneously, or is the maximum number of requests that can be running concurrently? For example, if I have a page that loads up some images, CSS files, scripts and content, each of those could reasonably be on a separate request socket with a modern browser. Is each of those sockets counted against the "max", or is it counted only as 1 since they are all requests from the same client address?

• Bluetooth RFCOMM / SDP connection to a RS232 adapter in android

  - by ThePosey

  Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77_Commands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect() method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine. The below is merged from a similar question which was successfully resolved by the selected answer here: How can one connect to an rfcomm device other than another phone in Android? The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss. Using "sdptool browse" from my Linux host comes up empty, so I surmise that the chip in question simply lacks SDP support.

• Thinking Sphinx not working in test mode

  - by J. Pablo Fernández

  I'm trying to get Thinking Sphinx to work in test mode in Rails. Basically this: ThinkingSphinx::Test.init ThinkingSphinx::Test.start freezes and never comes back. My test and devel configuration is the same for test and devel: dry_setting: &dry_setting adapter: mysql host: localhost encoding: utf8 username: rails password: blahblah development: <<: *dry_setting database: proj_devel socket: /tmp/mysql.sock # sphinx requires it test: <<: *dry_setting database: proj_test socket: /tmp/mysql.sock # sphinx requires it and sphinx.yml development: enable_star: 1 min_infix_len: 2 bin_path: /opt/local/bin test: enable_star: 1 min_infix_len: 2 bin_path: /opt/local/bin production: enable_star: 1 min_infix_len: 2 The generated config files, config/development.sphinx.conf and config/test.sphinx.conf only differ in database names, directories and similar things; nothing functional. Generating the index for devel goes without an issue $ rake ts:in (in /Users/pupeno/proj) default config Generating Configuration to /Users/pupeno/proj/config/development.sphinx.conf Sphinx 0.9.8.1-release (r1533) Copyright (c) 2001-2008, Andrew Aksyonoff using config file '/Users/pupeno/proj/config/development.sphinx.conf'... indexing index 'user_core'... collected 7 docs, 0.0 MB collected 0 attr values sorted 0.0 Mvalues, 100.0% done sorted 0.0 Mhits, 99.8% done total 7 docs, 422 bytes total 0.098 sec, 4320.80 bytes/sec, 71.67 docs/sec indexing index 'user_delta'... collected 0 docs, 0.0 MB collected 0 attr values sorted 0.0 Mvalues, nan% done total 0 docs, 0 bytes total 0.010 sec, 0.00 bytes/sec, 0.00 docs/sec distributed index 'user' can not be directly indexed; skipping. but when I try to do it for test it freezes: $ RAILS_ENV=test rake ts:in (in /Users/pupeno/proj) DEPRECATION WARNING: require "activeresource" is deprecated and will be removed in Rails 3.

Any ideas where to go from here? I can run the command line manually: /opt/local/bin/indexer --config config/test.sphinx.conf --all which generates the output as the rake ts:in, so no help there.
