subscriber state before dial
Hi All
After a Dial() I get:
WARNING[7964][C-000075a8]: app_dial.c:2437 dial_exec_full: Unable to create
channel of type 'SIP' (cause 20 - Subscriber absent)
if the subscriber is not registered.
Is there a way from dialplan to know, *before* Dial(), if a destination
Subscriber is
a) not registered or
b) busy ?
I need to redirect a call to some other Subscriber if (s)he is not there

filtering icmp - second try
Hi All
Is the filter rule bellow supposed to classify icmp request/reply packets?
$TC filter add dev eth2 protocol ip \
parent 1:0 prio 1 u32 \
match ip dst 192.168.0.1 \
match icmp type 8 0xff flowid 100
$TC filter add dev eth2 protocol ip \
parent 1:0 prio 1 u32 \

match icmp type 0 0xff flowid 100
it is accepted by tc but I think it is not

Yet another htb rules generator
Dears
I wrote a small program that converts a ASCII hierarchical HTB model (nice name, no!)
to those nasty bunch of tc statments.
It is a 0.0.0-prealpha code so be gentle! ;-)
This means a lots of buffer overflows and the like. I am not worried with these by now.
My concern is: is this a good idea? any future on that? is it a duplicated effort?
Would somebody tell me if it could be of some

match''ing packets by size
I visited yesican.chsoft.biz and the author proposes a way to match packets by
less than some size .
Here is the thing:
match u16 0x0000 0xffb0 at 2
With this match he says that packet with less than 80 bytes will match the rule.
Well, 0xffb0 translates to 1111 1111 1011 0000 (which is -80 BTW).
So, if I am correct any packet with bits 4 and/or 5 set (together with any of

passive FTP trafic control
Hi All
How to classify packets belonging to a FTP session?
Port 21 session is easy. but what about data transfers? Their port numbers
(both) are above 1024.
I was thinking about ip_conntrack_ftp. Something like:
iptables -A FORWARD -p tcp --sport 1024: --dport 1024: \
-m state --state ESTABLISHED,RELATED -j CLASSIFY --set-class X:Y
But what if I also have ip_conntrack_irc, for instance.

match mark problem still resists
Dear All
I am kinda frustrated with the lack of help some developers are dispensing to this
problem (read ignoring it).
A few days ago (december 22th) I reported a problem with ''tc filter match mark''
against 2.4 kernel series and got no answers that could lead me to any solution.
This is a steady problem that occurs in kernel 2.4 series and match mark (at
least for me).

iptables mark and u32 filter
Hi All
I''d like to use an iptables mark together with u32 filter. Something like this, for instance:
tc filter add dev imq0 protocol ip parent 1:0\
prio 2 handle 55\
u32 match u8 1 0xff at 0x09 flowid 1:22
(all icmp packets marked with 55 goes to class 1:22)
But I got ''Illegal filter ID'' as answer. Is this combination possible?

Dear all
1) Could you happen to know why smbmnt, smbmount and smbumount are not
compiled whem I rum "make" from the source directory?
I found (for example) bin/testparms in the PROGS1 Makefile variable but
no reference to those little fellows.
2) How do I change the config directory to be /etc instead of
/usr/local/samba/lib? I tryed "./configure --sysconfdir=/etc" and it

"x" permission interpretation under Windows
Hi
How does Windows interpret the 'x' attribute for the file's 'other' attribute
field?
If I give a *file* a 0775 permission Windows XP clients cannot see the file.
Not even the group members.
If I change this permission to 0774 the file becomes visible to everyone.
(smbclient sees the file either way).
This file in under a directory which has 2775 as permission and
