issue with fail2ban letting IP's through
by David Mehler 16 May '11

16 May '11

Hello, I'm using fail2ban to block bots in conjunction with existing iptables rules. Here's a few rules from my iptables configuration: # # Set up a temporary pass rule so we don't lock ourselves out when #doing remote ssh iptables -P INPUT ACCEPT # # flush the current rules iptables -F # # Allow SSH connections on tcp port 22 iptables -A INPUT -p tcp --dport 22 -j ACCEPT # # Set default policies for INPUT, FORWARD and OUTPUT chains iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT iptables -A INPUT -s 202.0.0.0/8 -j DROP This morning the ssh fail2ban jail blocked this: 202.205.176.125 and the email sent gave me this ip range: inetnum: 202.205.176.0 - 202.205.191.255 That shouldn't have even been seen it should have been blocked by the 202/8 drop rule before fail2ban even saw it. Is that not so? Suggestions welcome. Thanks. Dave.

Apache in chroot reporting every client is 16.0.0.0
by Jason Pyeron 15 May '11

15 May '11

Not sure where to start on this. I went to examine a log file today and noticed a password protected internal file was being accessed from 16.0.0.0. Upon further review every log entry has the same IP. Accessing apache from localhost also reports 16.0.0.0. Google is not being my friend right now, any advice? Kernel: 2.6.9-89.0.29.Elsmp In the chroot: httpd-suexec-2.0.52-41.ent.7.centos4 httpd-devel-2.0.52-41.ent.7.centos4 httpd-2.0.52-41.ent.7.centos4 -jason -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.

Centos 5.5 mmap.c and mmap hints
by Frank Chang 15 May '11

15 May '11

Good morning, We are trying to figure out how to properly provide adresss hints to mmap on 32-bit Centos 5.5. Does any documentation exist about to how to provide address hints to mmap on 32-bit Centos 5.5? If so, where can we find this documentation. In order to understand mmap better, we decided to try to find the Centos 5.5 source code for mmap.c. We already installed the kernel source code using the following commands : # cd /tmp # wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/kernel… # rpm -ivh kernel-2.6.18-8.1.8.el5.src.rpm However, we can't find the source code for the functions: void *mmap(void *start, size_t length, int prot, int flags, int fd, off_t offset); and int munmap(void *start, size_t length); Where could we obtain the source code for the system function: void *mmap(void *start, size_t length, int prot, int flags, int fd, off_t offset)? Thank you. We have already run the following commands $ su # vi /etc/sysctl.conf ...and append vm.vdso_enabled = 0 vm.mmap_min_addr = 4096 # # /sbin/sysctl -p ... vm.vdso_enabled = 0 vm.mmap_min_addr = 4096 # exit Thank you.

ApacheDS vs OpenLDAP
by aurfalien＠gmail.com 14 May '11

14 May '11

Hi all, Wondering if any of you have thoughts/experiences with ApacheDS? We've all had trials and tribulations regarding OpenLDAP and while its basically working pretty well in a master/slave relationship, ApacheDS claims more robust replication, etc... Granted I am working with the version bundled with CentOS, I do understand that the latest OpenLDAP is wayyyyyyy betterrrr :) - Aurf

Or is ClearOS the only thing sensible enough for that? Are you talking about IPA, Les? mark
