Partial HOSTS file read

  • 772

I've a new entry that I put in the HOSTS file:

10.7.4.94 COMMRTU7 commrtu7 commRTU7

The first two entries ping, but the third one won't ping. I have a list of entries like this that work fine, any ideas why this won't?

  1. make your entry just:

    10.7.4.94 commrtu7

    and then try to ping all three

    ping COMMRTU7 
ping commrtu7 
ping commRTU7

    They are all the same.

    Thank you to the answerers who gave me good information.

    The problem turned out to be that there was a '^M' after the line (right after the entry in question), that didn't show when you CATed a file, but you could see in VI. After removing the '^M' it worked as normal.

    The reason it came out wrong was that I edited the HOSTS file on Windows in Notepad. The way to do it right is to use a Unix editor, or use TextPad on Windows and Save to a UNIX file format.

  3. I have no idea why it doesn't work, I am actually surprised that it appears to be case sensitive, even though RFC 952 dictates otherwise. Are you sure that the tru64 implementation is case sensitive to begin with?
