Lighttpd

If you did not find logs under /var/log/lighttpd/, then check if that exists and if user www-data has permission to write there. Similarly, does /var/cache/lighttpd/uploads exist and is it writable by user www-data?

Check the directory path ls -ld /home/firefall You probably did not give user www-data permission to traverse this directory.

I decided it would be better to host the hosts in default /var/www/ folder. after a little configuration, localhost works, but virtual hosts times out :(
All i changed is:
1. changed virtual host path to /var/www/host.local(didn't worked)
2. server.document-root = "/var/www/html"(localhost works)

Maybe i'm trying to open the vhost in an unproper way? Now i'm trying via "http://host.local", and it doesn't work.

but virtual hosts times out

That sounds like a DNS or name service problem/misconfiguration before requests reach lighttpd.

You might check your lighttpd access log to see if the request are reaching lighttpd.
You might test using a command line client, such as curl, as curl allows you to connect to localhost and pass -H "Host: my.virtual.host"

When i'm reaching http://host.local and it times out, access.log doesn't show the request.
When i tried "curl -H "Host: host.local" http://localhost", and it gave me 404 response, but the request didn't show up in the access.log.

Is there a way to fix this?

There are many possibilities why it did not show up in the access log: you may not have configured lighttpd to enable the access log. You may not have restarted lighttpd after changing the configuration. You may not have configured an appropriate server.document-root for "host.local". ...

There are many, and they are outside the scope of this forum, as they are not related to lighttpd configuration.

If you are having trouble with basic DNS and name services, then perhaps you're not yet ready to use virtual hosts.

Please consider trying one small thing at a time, get it working, and then build your config from there, continuing to add and test one feature at a time.
