RMySQL integer range bug (PR#1400)
...ssion from: (NULL) (131.220.6.43)
There is a bug when retrieving values out of MySQL (3.23.36) which are of type
UNSIGNED INTEGER(10). The values can vary between 0 and 2^32 but R only accepts
those below 2^31-1. Anything above goes as 2^31-1.
thats what one gets:
print(quickSQL(con,"select ip_dst from iphdr where ip_dst>=2212233216 limit
5"))
ip_dst
1 2147483647
2 2147483647
3 2147483647
4 2147483647
5 2147483647
and thats what the numbers really are (conversion to character type first):
print(quickSQL(con,"select concat(ip_dst) from iphdr where ip_dst>=2212233216

TCNG HTB Branching the class not working. (bug or what)
...I find tcng somewhat easy to use (although
lack proper doc. of its usage).
I want to control traffic of several IP Addresses connected to my LANSIDE.
What I want is , i want to separate certain bandwidth to all my clients.

htb() {
class ( rate 400kbps, ceil 400kbps) if ip_dst == 192.168.0.9

It compiles and work well with no syntax error.
However For each IP I want to prioritize the traffic. Say, priority 1 for
http traffic and priority 2 for other, each host limiting withi...

TCNG HTB priority and bandwidth
Hi,
I have several users on the lanside each allocated separate IP addresses.
I need to allocate th traffic to each IP addresses certain portion of
total uplink.
Say, 192.168.0.2 rate 128kbps, ceil 128kbps.
192.168.0.3 rate 65kbps, ceil 128kbps
129.168.0.4 rate 64kbps, ceil 64kbps.
and so on....
Also, for each user i would like to prioritize the traffic within the
allocated bandwidth.

[patch] Raw sockets in jails
Although RAW sockets can be used when specifying the source
address of packets (defeating one of the aspects of the jail)
some people may find it usefull to use utilities like ping(8)
or traceroute(8) from inside jails.
Enclosed is a patch I have written which gives you the option
of allowing prison-root to create raw sockets inside the prison,

Re: did you manage to solve dst cache overflow ?
...happen. If it
doesn''t help go keep mailing me :).
No i didn''t overcome my problem yet. But I''m close. I did what i sad in the
first line of my mail and it help for some time.
I think htb has some kind of defect when using ds_mark. When I were shaping
download only using ip_dst it were working great but when i started using
ds_mark to shape upload this bad things started to happen. Today I''ve
splitted making NAT and shaping on two boxes so I can do ip_src in htb and
then when the traffic is already shaped I can NAT it. If it works we will

Good luck.

PPPoE and shaping
Hi all,
I have a little problem with my home-made slackware linux server.
Here is the scenario:
1. I have a local wifi network
2. my server do masquerading and exit in internet via a PPPoE connection
Goals:
1. not use SQUID
2. shaping the traffic with classes
3. emule connection must have minimum priority and a band-limit of
10KBytes/s in uplink (server--->internet)
Any idea?
Thx,
Diego
