Replying to myself... Just in case if someone has similar problem.
The proxy configuration script did not work because myIpAddress()
incorrectly returned IPv4 localhost address: "127.0.0.1" (in google-
chrome) or IPv6 "::1" (in firefox). I don't know if this is a bug in
myIpAddress(), or the reason was in /etc/hosts file which was
overwritten by NetworkManager as follows:
# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.1.66 realhostname # Added by NetworkManager
127.0.0.1 localhost.localdomain localhost
::1 realhostname localhost6.localdomain6 localhost6
The workaround is to add the following script in
/etc/NetworkManager/dispatcher.d:
************ cut here **********
#!/bin/sh
export PATH=/sbin:/usr/sbin:$PATH
rewrite_hosts ()
{
tmphosts="/tmp/02-nm-tmp.hosts"
cp /etc/hosts "$tmphosts"
cat "$tmphosts" | sed \
's/^::1\t.*$/::1\tlocalhost6.localdomain6\tlocalhost6/' > /etc/hosts
}
if [ "$2" = "up" ]
then
rewrite_hosts
fi
************ cut here **********
