Package: polipo
Version: 1.0.4+58-1
Severity: important
File: /etc/network/if-down.d/01polipo
Regularly when I have a network outage -- such as when I unplug my
laptop to take it to a meeting -- polipo switches to "offline mode",
but when I plug the network back in, it doesn't go back into "online
mode". This is also the case for long outages on my wifi interface,
such as when I restart my wireless router.
Today I noticed that this is caused by Debian-specific "cleverness"
that polipo installs by default into /etc/network/if-{up,down}.d/; I
can only assume these scripts have not been properly tested with my
kind of network use cases.
Example symptom:
$ curl -sLI http://fnord.com/ | head -1
HTTP/1.1 502 Disconnected operation and object not in cache
$ env -u http_proxy curl -sLI http://fnord.com/ | head -1
HTTP/1.1 200 OK
This is my /etc/network/interfaces:
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet dhcp
auto ath0
iface ath0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
wpa-roam-default-iface ath0-default
iface ath0-default inet dhcp
My /etc/polipo/options has not been touched:
# See the /usr/share/doc/polipo/README.Debian file for details on this file
method any
#method static
#method manual
#method dhcp
#method bootp
#method ppp
#method wvdial
NetworkManager is *not* installed.
By the way, I suggest you replace
( grep -qsxi '^[[:blank:]]*method[[:blank:]]*any[[:blank:]]*$' $OPTION_FILE
\
|| grep -qsxi '^[[:blank:]]*method[[:blank:]]*$METHOD[[:blank:]]*$'
$OPTION_FILE )
with
grep -qsxi
"^[[:blank:]]*method[[:blank:]]*\\(any\\|$METHOD\\)[[:blank:]]*$' $OPTION_FILE
