Bonjour,



J'ai un soucis avec syslog-ng et mes logs iptables, non seulement syslog-ng destine les logs vers /var/log/firewall mais je les trouve aussi dans ma console et à la sortie de la commande dmesg malgré un dmesg -n 1. J'ai essayé tout les niveaux (info, warning, ...) de log et c'est tjrs le même résultat. :o



ma règle iptables:

iptables -A INPUT -m state --state INVALID -m limit --limit 3/s -j LOG --log-tcp-option --log-ip-options --log-level warning --log-prefix "## INVALID INPUT ## "



mon fichier de conf syslog-ng.conf:





#

# Configuration file for syslog-ng under Debian

#

# attempts at reproducing default syslog behavior



# the standard syslog levels are (in descending order of priority):

# emerg alert crit err warning notice info debug

# the aliases "error", "panic", and "warn" are deprecated

# the "none" priority found in the original syslogd configuration is

# only used in internal messages created by syslogd





######

# options



options {

long_hostnames(0);

# (default is 60)

time_reopen(10);



# the time to wait before an idle destination file is closed

# (default is 60)

# the number of lines buffered before written to file

# you might want to increase this if your disk isn't catching with

# all the log messages you get or if you want less disk activity

# (say on a laptop)

# (default is 0)

#sync(0);



# the number of lines fitting in the output queue

log_fifo_size(2048);

# (defaults are 0, 0, 0700)

#dir_owner(root);

# enable or disable DNS usage

# syslog-ng blocks on DNS queries, so enabling DNS may lead to

# a Denial of Service attack

# (default is yes)

use_dns(no);



# maximum length of message in bytes

# this is only limited by the program listening on the /dev/log Unix

# socket, glibc can handle arbitrary length log messages, but -- for

# example -- syslogd accepts only 1024 bytes

# (default is 2048)
