问题 How do I get command line utilities like ping to use the default proxy in Windows XP. proxycfg -u sets the proxy to the default (IE) proxy alright, but it doesn't seem to be working. Update : I am behind a proxy and would like a way to check if a site is up or not hence trying to use ping! Also would like a way to telnet (without using Putty) to a specific site and port to check connectivity. 回答1: A proxy is usually used for web (HTTP) traffic, ping uses ICMP, which is a completely separate

问题 I am using Windows 7 x64. Using a bat script, I need to check whether I am able to connect to some specific ports on a server using telnet. If successfully connected, the server displays a menu, or else a message like this : Connecting To xxxxx...Could not open connection to the host, on port xxxxx: Connect failed. For my purpose, the server has several ports to be tested and I don't want to complicate things by logging in or navigating menus. I just want a simple output indicating whether

问题 I'm trying to write a script to allow me to log in to a console servers 48 ports so that I can quickly determine what devices are connected to each serial line.

The problem I'm facing is that if I start a telnet

问题 I have a VBA library that does FTP, I'd like to do telnet as well. At the moment I'm shelling out to a Perl script that does the telnet based on a text file, but I'd like to drive the telnet connection natively from within the VBA. Does anyone have any source for this? I don't want to use an add-in, I need the code to be self-contained. 回答1: If you can use the MS WinSock control (also see using winsock in VBA) More resources: MSDN Library: Using the Winsock Control (Visual Basic) Winsock
