Long time, no postings. I've been busy -- more on that another time. Last week I picked up a D-Link DCS-920 wireless IP-Camera on

Amazon for $62 (after rebate). I did not have high hopes for such an affordable camera, but was pleasantly surprised with the installation process and resulting image quality. The last time I bought one of these types of cameras, the installation process was a little complicated. This time, it was far easier. By default, the camera has DHCP enabled, ftp errors and solutions so you plug it into your network using the supplied Ethernet cable and it grabs an address on your network. I looked at my router status page to see that it had added itself. Mine also registered itself on my network as "dcs-920" so I could connect to its admin page at http://dcs-920. Nice! The default login is "admin" and the password is blank. The next step was to add the camera to my wireless home network. Here is how to do that. Go to the Setup>>Wireless page and click the "Site Survey" button. This scans the available wireless networks and shows their signal strength. (My network was right at the top as the strongest.) Select the network. Now, the wireless network password has to be set. This step always seems confusing and error-prone, and I'm not sure why. Perhaps there are too many security options. Before I set up the camera, I went back to my wireless hub and checked its settings. It was set for "WEP, Open System, 64-bits, Hex." I

Article Detail When testing an FTP connection you may receive one of the following errors: Socket Error # 11001, Host not found: Check that the hostname ws_ftp failed to create socket or IP address has been entered correctly. Socket Error # 11004, Unable to connect:

Check to make sure there isn't a trailing or leading space character on the FTP hostname. Also, enter the hostname or IP

address, not a URL, e.g. if you have entered something like ftp://my.hostname.com/ then change it to my.hostname.com Socket Error # 10061, Connection refused: The hostname is correct, but either the FTP server is not listening http://www.tsheffler.com/blog/tag/tcpip-socket-error/ on the port, there is no FTP server running, or a firewall is blocking the connection. Socket Error # 10093: This can happen when the network connection goes down, e.g. the FTP server is no longer connected to the network. Socket Error # 10038: If you are using Serv-U modify your FTP server settings so that the following are unticked: “Block anti time-out schemes”, “Block FTP_bounce attacks and FXP”, and “Block users http://support.2brightsparks.com/knowledgebase/articles/213469-common-ftp-errors-and-socket-error-messages who connect more than 6 times within 60 seconds for 30 minutes.”. You may also want to be sure you are using a passive connection. Socket Error # 10039: There may be a problem getting the IP address for the hostname. Socket Error # 10052: The host you were connected to crashed and rebooted. Try reconnecting at a later time. Unable to connect: Connection time out: The hostname may be incorrect or the FTP server may be behind a firewall. Unable to connect. Not logged in: The username and/or password is not correct. Unable to connect. Error connecting with SSL: The FTP server does not support SSL, or you are using implicit SSL and it only supports explicit, or the wrong port number is being used. If you are using implicit SSL then you probably need to use port 990 instead of port 21. When running a profile that connects to an FTP server you may receive the following errors in the log file: Scan failed (-1): Read Timeout: The connection to the FTP server was lost, and the attempts to reconnect failed, while trying to scan it for changes. Other common problems are: Can connect to the FTP server but when trying to choose the destination directory nothing happens for a very long
can't I relay Internet e-mail through my BBS? Why can't I send Internet e-mail from my BBS? Why can't my BBS receive Internet e-mail or inter-BBS instant messages? http://www.synchro.net/docs/tcpip_faq.html Why can't users connect to my FTP server? Why do FTP clients lock-up or time-out when listing directories or downloading files from my FTP server? Why do external programs that use socket I/O not work http://stackoverflow.com/questions/100841/artificially-create-a-connection-timeout-error on my Windows BBS? Why do some or all of my servers get bind errors when starting or recycling? How many nodes/clients/users can I support with my Internet connection? Question: What inbound ports do I socket error need to open in my firewall? Answer: Depends on which Synchronet servers and services you wish to make available to Internet clients and which ports you have configured those servers and services to listen on. The default Synchronet installation enables servers and services on the following ports: ProtocolTCPUDPComments Telnet23-For Telnet logins (highly recommended) SSH22-For SecureShell logins (recommended) RLogin513-Optional for quick-login from RLogin clients (e.g. SyncTerm) SMTP25-Necessary for receiving Internet e-mail ftp server test and inter-BBS instant messages POP3110-Allows BBS users to check their e-mail using standard Internet mail clients (e.g. Outlook Express) FTP21-Allows access to the BBS file/download areas using a standard FTP client or web browser HTTP80-Required for access to the BBS's web server NNTP119-Allows BBS users to read and post messages using standard news readers/clients Gopher70-Archaic protocol allows reading of messages and other BBS info IRC6667-Allows Internet Relay Chat (IRC) clients to connect to your BBS Finger7979Allows remote querying of BBS user info, who's online, and other BBS info SYSTAT1111Allows remote querying of who's online (aka Active Users) QOTD1717Allows remote querying of the current auto-message (aka Quote Of The Day) MSP1818Allows incoming inter-BBS instant messages without SMTP connectivity Enabling connectivity to Synchronet through your firewall is no different than enabling connectivity to any other TCP/IP server. Follow your firewall documentation for forwarding or opening ports for TCP/IP servers located "behind" the firewall. Your firewall may have the option of placing the entire BBS computer in a "DMZ" (opening all its ports to the public Internet), but doing so is not normally recommended. Question: How come my friends can't connect to my BBS at my 192.168.x.x, 172.[16-31].x.x, or 10.x.x.x IP address? Answer: The IP address ranges listed above are reserved

These errors are very rare (usually when my connection gets dropped by our internal network). How can I generate this kind of effect artificially so I can test our software? If it matters the app is written in C++/MFC using CAsyncSocket classes. Edit: I've tried using a non-existant host, and I get the socket error: WSAEINVAL (10022) Invalid argument My next attempt was to use Alexander's suggestion of connecting to a different port, e.g. 81 (on my own server though). That worked great. Exactly the same as a dropped connection (60 second wait, then error).

I understand this answer didn't intend to suggest using google.com:81 but the point here is to use a different port that is blocked. So you can always use
