[squid-users] I have found this Squid-Cache designed blacklist, anyone seen it?

[Eliezer Croitoru]

Hey,

 

While I was wondering around github I stumbled upon this repository:

https://github.com/maravento/blackweb

 

Which claims to centralize many blacklists and designed for the use with
Squid-Cache.

Anyone have seen or tried this list?

 

I have seen it and thinking about writing an enhancement to this blacklist
scripts.


Can anyone help with this?

 

Eliezer

Re: [squid-users] Squid SNMP remote monitoring and IP fragmentation

[Peter Viskup]

Communication is ok. Problem was with pcap filtering based on port
number. Only the first fragment of the packet have this information.
All others have port fields empty. More information in tcpdump man
page in IP Fragmentation section.

In new packet capture the request for 87 OIDs is replied with 87
corresponding values.

Issue with not consistent data values in Zabbix are related to Zabbix
server post-processing.

OID *.1.5.2.2 is the mgr:client_list table data, excluding the TCP_*
code breakdown for responses given.

Is this SNMP value present in the cache-manager pages?
If so it would be pretty simple to write a script that will extract the 
relevant data via http.

You do know there is a difference between binary and textual
representations of these things right?

The packets contain the full OID binary data, and the snmpwalk output is
abbreviated down to textual names which may be half or even a third the
size. Then there is the protocol headers in packets which in the case of
single SNMP queries like these are much larger than the OID and data itself.
