I have an Internet proxy that is running FreeBSD 5.4-RELEASE. This
server has been up and running beautifully for about a year and a
half with no issues.
Just the other day I had a user try to connect to a host on the
Internet and her connection was failing. At first I thought that
it was the receiving host's issue because we were having no other
Internet connection issues through the proxy. However, I ran a
test connection from my home and found that everything worked fine.
After investigating the issue I found that if I ran a "route get
xxx.xxx.xxx.xxx" on my proxy server it would take 1.25 minutes for
the route to come back. This same delay was also experienced if I
tried to use telnet to open a connection to the remote host. After
about 1.25 minutes the session would open successfully.
So I ran "route monitor" and found that when I execute the "route
get" command the RTM_GET returns the appropriate route almost
immediately but there is still a substantial delay in the "route
get" command displaying the response.
I ran this test on three other 5.4 and one 5.5 servers and found
that they all had the same issue. However, if I ran the same
"route get" command on a 5.3 server it works just fine.
After all of my testing I wanted to know exactly what IP address
range was affected and found that it is limited to just 60 address
within a specific range (I can provide the range).
Any help you could provide would be greatly appreciated.
This is almost definitely a DNS issue.
Try "route -n get" or "telnet -N" and see if it still happens.
