2007-Nov-23 - Trouble shooting ... (network & apps)
Windows: 1. Domain name resolution error while sending a mail. # ping {domain_name} -> Return corresponding IP1, correct. But # nslookup {domain_name} -> Return IP2, incorrect. Troubleshoot: (>> input ; << output) 1) >> ipconfig /all << Windows IP configuration & Ethernet adapter Local Area Connection 2) >> nslookup << Default Server & address >> server {DNS_IP} -- Here reset the correct DNS server IP. << Default Server & address >> IP1 << The corresponding domain_name -- This step checks whether the DNS is correct. 3) Disable and enable network connection if anything changed. 2. Java Applet load failed. 1) Install MSJav 2) Open Internet Options -> Advanced, uncheck Java (Sun) and check MS VM. 3. HTTP download failed or file not found. a. Check IIS (http server) privilege. Add everyone if necessary. b. Add MIME Types: Open IIS, open Default Web Site Properies -> HTTP Headers -> MIME Types -> New: .* application/octet-stream 4. Failed to connect to http server. (Unauthorized.) a. Open IIS, open Default Web Site -> Properties -> Directory Security -> Authentication and access control. Click Edit. Check Enable anonymous access. Or b. Type username and password in client. 5. Windows 2003 + IIS 6.0 "Service Unavailable" error. Open IIS, then open Web Sites -> Properties -> Service. Check "Run WWW service in IIS 5.0 isolation mode". 6. VMWare failed to launch peer process. Probably caused by low disk space. Free some space, and stop all vmware related processes, then try again. 7. VMWare Station not able to take snapshot (the menu is grayed). It's because the VM is created by old version of VMWare. Select VM->Upgrade Virtual Machine.
8. Application displays junk code.
There are 3 kinds of junk code correspond to different solutions:
a. Displays "???".
Code page for the language version of the application is not installed. Open Control Panel -> Regional Options to install it.
b. Displays tofu.
The font is incorrect. Add the correct font to Fonts in Control Panel.
c. Displays other language codes.
Select the language that match the language version of the application in the Advanced tab of Regional Options in Control Panel.
Linux: 1. "ifconfig" command does not work in Turbo linux when remote access by PuTTY. Change the Keyboard setting in PuTTY: select Control-H, rxvt, SCO. 2. Failed to access Suse linux by PuTTY. Change the SSH authentication type: Config -> SSH -> Auth: check SSH1. 3. Postfix only binds to localhost (127.0.0.1). 1) Open /etc/postfix/main.cf 2) Search for: inet_interfaces = localhost 3) Change it to: inet_interfaces = All 4. Program make/build error: Makefile is older than Makefile.org, Configure or config. (Error code 1) Probably caused by lagging system time. Just change system time to current and try again.
