Just for what it is worth because I am very new to this. I am pinging antani
with reliable. I just started regular pinging a few days ago. Antani is
giving me back pings at 100%. Latency is very long though, about 18 hours.
This puzzles me because it seems the echolot pingers show a latency of about
an hour.

However, in all other re-mailer pings, my stats from reliable pretty well
match those generated by the echolot pingers.

SORBS has not been a problem for me. I just don't understand the latency
difference that seems to stand out for antani.

Anybody have a thought on this? I am curious why I would show an 18 hour
latency and the echolot pingers a latency of about an hour.

I don't plan on publishing my stats, they are for my own use to see if my
re-mailer is having problems connecting to others. it is a diagnostic aid to see
if I am doing something wrong. (Which I usually am :(

Sorry to diverge from the SORBS topic.

On second thoughts, maybe I will become a capable remop in the next 200 to
300 years :)   I have so much to learn.
