Re: [Debian-NYC] debugging network slowness [was: Thanks for yesterday!]



OK Sorry about that!  Here goes again:

steve@francisco:~$ time dig +short @208.59.247 nytimes.com
;; connection timed out; no servers could be reached

real    0m15.022s
user    0m0.016s
sys    0m0.008s
steve@francisco:~$


steve@francisco:~$ time dig +short @192.168.2.1 nytimes.com
199.239.136.200

real    0m0.020s
user    0m0.004s
sys    0m0.012s
steve@francisco:~$


I hope this is what you asked for.

Steve

When cutting and pasting transcripts from the shell, it's useful to show
the leading prompt, the command you ran, the full output from the
command, and the trailing prompt.  For a series of commands like this,
you don't need to interleave it with english asides; the transcript will
speak for itself.

You might be interested in these suggestions for future troubleshooting
like this:

(feel free to edit and add your own suggestions!)


so i'm not entirely sure i'm reading your transcript right; it looks
like you ran:

  time dig tshort @208.59.247.45 nytimes.com 199.239.136.200

but i had suggested that you run:

  time dig +short @208.59.247.45 nytimes.com

( +short is quite different from tshort, and the extra IP address you
added to the command appears to be actually the output of the command i
had run )

Also, i didn't see any timing or queries against the first IP address
you had listed as a resolver for both systems: 192.168.2.1.

Can you try again?
