Why no TCP_HITS using squid-deb-proxy

  • 772

I've followed all the advice here and the server log file updates when I do an update on another computer on the network.

However, I never see any TCP_HITs. I even grepped for them. This is some of the tail -f output.

It may be worth mentioning that the server is running Lubuntu 14.04, while the clients are running Ubuntu 14.04. However, I made sure I added the missing repos ("updates", I think) to the server's sources.list

What am I missing?

EDIT: My allowed-networks-src.acl looks like this:

# allowed-networks-src.conf
# 
# network sources that you want to allow access to the cache

# private networks
10.0.0.0/8 
172.16.0.0/12
192.168.0.0/16
192.168.1.0/255.255.0.0
192.168.1.202
192.168.1.201
192.168.1.200
127.0.0.1

# IPv6 private addresses
fe80::/64
::1/128

# additional non-private networks can be added to the directory:
#  /etc/squid-deb-proxy/allowed-networks-src.acl.d

  1. I had the same problem for several days after a fresh install, using all the default settings except adding dl.google.com to mirror-dstdomain.acl. I'd always get TCP_MISS.

    The solution (after many many tries) was to add the exact network to allowed-networks-src.acl (don't forget to restart squid3 && restart squid-deb-proxy). Since then I see the beautiful TCP_MEM_HIT on every package.

    (My network is 10.10.10.0/24, which is part of the 10.0.0.0/8 allowed in allowed-networks-src.acl. I do think this behaviour is not nice in a system calling itself zero config.)
