Retaining ping response
I'm looking to see if an email server exists.
I type in 'ping' and its name in the Run dialog. Three responses come up very briefly, then the display disappears. How can I get it to remain on the screen? I used to know how but have forgotten. TIA to those with better memories, or at least younger memories. -- I love a good meal! That's why I don't cook. |

Start a Command Prompt via "cmd" in Start : Run then type the "ping www.some.com" in the new Command window ? ******* Or using Start : Run cmd /k ping www.sun.com and the Command window will remain open until you dismiss it. Typing cmd /? will give a long help page with the options. When constructing long commands with paths having spaces, you'll need copious usage of double quotes around things, to make it work well. In the above, I got away without them. Paul |

They use the console window (stdout) of the shell in which they run. If you run a DOS-mode program by having the OS invoke a shell for it, the shell loads, the program runs, and then the shell unloads which takes its console window with it. If you want to continue viewing the output of the program, you need to keep the shell open - so load the shell yourself. Run: cmd.exe Then enter the DOS-mode program you want to run, like ping.exe. If you want to run programs that require administrator privileges, you need to load the command shell with admin privs. Note that not all servers will respond to ping. Many consider it a waste of their resources to be spending time communicating with a client that just wants to see if the server is both reachable and responsive. The admin of the server or boundary host (to their server farm) may disable ICMP 0 and 8 for echo and reply (ping) in their firewall. ICMP packets can be variable in size, and ping has been abused in [D]DOS ([Distributed] Denial of Service) attacks to overload a server and to create covert channels (ICMP tunnels) for communication. Perhaps a better way to see if you can reach and connected to an e-mail server is to start a session with it. Use telnet to connect to the server. Even if it uses SSL/TSL, you can still check if a simple non-encrypted session can be started. Run: telnet hostname port This is a DOS-mode program whose stdout is the shell's console window. So load a shell and then run the command, so you can continue seeing the output of the program. You are looking for the server to connect and to respond with a status, not to actually perform a mail session. hostname is whatever is the hostname for the mail server; e.g., mail.domain.tld. port depends on what type of mail server to which you are connecting. You didn't say if you are trying to connect to a POP or IMAP server (for you to receive e-mail) or to an SMTP server (for you to send e-mail). For ports, use whatever port your e-mail provider says to use. Typically the port numbers a POP = 110, POPS = 995, IMAP = 143, IMAPS = 993, SMTP = 587 or 25, and SMTPS = 465. All ping will tell you is if you reached the server host, not if the server software is running on that host. IMCP will return responses if the networking is working on that host. It does not involve the server programs. Many server programs can run on the same host hence the differentiation by using different port numbers to distinguish which listening process (server) to which you want to connect on the same host. If you want to check you can reach the server host *and* that the server program (POP, IMAP, SMTP) is actually running and responsive, then telnet to the host to establish a session with the listener there. |

Ping -t hostname or ip address i.e. ping -t google.com Just X out of command prompt when your done. Hope this helps. JT -- |
