by Mohd Syakir 22 Feb '07

22 Feb '07

Hi, Sory to bother you with my new-user questions. i've got one redhat 9 box, acting as email server using sendmail. it use local /etc/passwd. last week i've just finished setting up a server, centos 4.4 as a replacement mail server for the red hat 9. i mainly refereing the tutorial at http://www.howtoforge.com/virtual_users_postfix_courier_mailscanner_clamav_…. with some modification, it's now working. i installed postfixadmin as it have freindly interface, because, beside me, other admin does not feel comfortable inserting the data through dump black and white command prompt. there is 2 problems: 1. what should i do so that the user does not have to fill thier full email address (user(a)domain1.com) at the login page of squirellmail. it's moreindly to just put "user" as they used before. 2. how do i convert all the previous email to the new mailbox format. anyone have had an experience doing this? please help me. thanks.

CentOS 4.4 blocking outbound connections?
by Neil Aggarwal 22 Feb '07

22 Feb '07

Hello: When I installed CentOS 4.4 (from the ServerCD) on my server, I told it not to install a firewall and I disabled SELinux. The server is a SuperMicro 5015P-TR. I set up my own /etc/init.d/firewall with these rules: #!/bin/sh # Firewall script # # Source function library . /etc/init.d/functions RETVAL=0 # Some definitions (Will need to change ETH0_IP to match your configuration) ETH0_IP=38.114.192.86 # See how we were called. case "$1" in start) echo -n "Starting firewall: " /sbin/modprobe ip_conntrack_ftp # Set the default policies to drop all packets /sbin/iptables -P INPUT DROP /sbin/iptables -P OUTPUT DROP /sbin/iptables -P FORWARD DROP # Flush any existing rules /sbin/iptables -F # Allow loopback traffic /sbin/iptables -A INPUT -i lo -j ACCEPT /sbin/iptables -A OUTPUT -o lo -j ACCEPT # Allow icmp protocol packets /sbin/iptables -A INPUT -i eth0 -d $ETH0_IP -p icmp -j ACCEPT /sbin/iptables -A OUTPUT -o eth0 -s $ETH0_IP -p icmp -j ACCEPT # Allow ssh connections from the outside world /sbin/iptables -A INPUT -i eth0 -d $ETH0_IP -p tcp --sport 1024: --dport ssh -m state --state NEW,ESTABLISHED -j ACCEPT /sbin/iptables -A OUTPUT -o eth0 -s $ETH0_IP -p tcp --sport ssh --dport 1024: -m state --state ESTABLISHED -j ACCEPT # Allow this sever to access DNS /sbin/iptables -A OUTPUT -o eth0 -s $ETH0_IP -p udp --sport 1024: --dport domain -j ACCEPT /sbin/iptables -A INPUT -i eth0 -d $ETH0_IP -p udp --sport domain --dport 1024: -j ACCEPT # Log any packets that are left /sbin/iptables -A INPUT -j LOG --log-prefix "INPUT " /sbin/iptables -A OUTPUT -j LOG --log-prefix "OUTPUT " /sbin/iptables -A FORWARD -j LOG --log-prefix "FORWARD " RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/firewall ;; stop) echo -n "Shutting down firewall: " # Flush the rules /sbin/iptables -F # Set the default policies to accept /sbin/iptables -P INPUT ACCEPT /sbin/iptables -P OUTPUT ACCEPT /sbin/iptables -P FORWARD ACCEPT RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/firewall ;; *) echo "Usage: firewall {start|stop}" exit 1 esac exit $RETVAL Now, I can ssh to it only from the other machines in the same rack. When I try to ssh to it from outside, I get this error in the /var/log/messages file: Feb 17 23:01:26 tweb kernel: OUTPUT IN= OUT=eth0 SRC=38.114.192.86 DST=24.175.73.85 LEN=48 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=TCP SPT=22 DPT=1118 WINDOW=5840 RES=0x00 ACK SYN URGP=0 If I log into the machine and try to ping an external IP, I get no response and nothing in the messages file. Is there some security setting on CentOS 4.4 that limits connectivity? Thanks, Neil -- Neil Aggarwal, (214)986-3533, www.JAMMConsulting.com FREE! Eliminate junk email and reclaim your inbox.

Re: [CentOS] php version 4.4 / ez publish

I have a silly question... why not install from source? http://www.php.net/downloads.php PHP 4.4.4 ----- Original Message ---- From: Michael Kress <kress(a)hal.saar.de> To: CentOS mailing list <centos(a)centos.org> Sent: Wednesday, February 14, 2007 2:48:37 PM Subject: [CentOS] php version 4.4 / ez publish Hi list, is there any repository on this world where I can stick to and update to a stable and hopefully secure and hopefully long supported version 4.4 of php? EZ publish's software requirements as of the current version tells me that it requires php 4.4 which doesn't meet what Centos 4.4 or its upstream provides. For a certain project I want to use ez publish. Is there any solution you see for that? Install a seperate server for that? (That's the least I wanna do). Or _does_ it work with php 4.3 under centos 4.4? Any experience?

Hello, I would like to replace one of the disks in a raid 1 array (software raid) in centos 4.4 for the purpose of saving the removed drive as a backup of the system. Replace it with a new disk and have the raod resync. That way the removed disk can be used to restore the system to that point in time if something dramatic occured. I have a number of questions, I can’t find the answers to and I don't have a system I can play with to see how the software behaves: 1) Do I need to partition the replacement drive or will the system do it after reboot? 2) Should I break the raid before replacement or just shutdown, replace and reboot? 3) I have also read that acronis 10 rescue CD can be booted and take a system image that way but I have not tried that yet.. In general, are these approaches a good idea for generating an offsite image backup?? Any help or input would be appreciated. Thank you, -ed-

Problem with Cacti and CentOS 4.4
by Matthew Martz 22 Feb '07

22 Feb '07

I just for the first time attempted to install Cacti from the RPMForge repo on CentOS 4.4. And I have to say that it hasn't gone very well at all. I have installed Cacti on Fedora a good 20 times with absolutely no problem. Basically the default rrds/graphs for localhost are generated but no other rrds/graphs are generated. When I look at the poller cache or snmp cache I see all the data. When I turn on Graph Debugging I get the following: RRDTool Command: /usr/bin/rrdtool graph - \ --imgformat=PNG \ --start=-86400 \ --end=-300 \ --title="DCN2948-1 - Traffic - Fa10" \ --rigid \ --base=1000 \ --height=120 \ --width=500 \ --alt-autoscale-max \ --lower-limit=0 \ --vertical-label="bits per second" \ --slope-mode \ DEF:a="/var/www/cacti/rra/dcn29481_traffic_in_19.rrd":traffic_in:AVERAGE \ DEF:b="/var/www/cacti/rra/dcn29481_traffic_in_19.rrd":traffic_out:AVERAGE \ CDEF:cdefa=a,8,* \ CDEF:cdefe=b,8,* \ AREA:cdefa#00CF00:"Inbound" \ GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \ GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \ GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s\n" \ LINE1:cdefe#002A97:"Outbound" \ GPRINT:cdefe:LAST:"Current\:%8.2lf %s" \ GPRINT:cdefe:AVERAGE:"Average\:%8.2lf %s" \ GPRINT:cdefe:MAX:"Maximum\:%8.2lf %s" RRDTool Says: ERROR: opening '/var/www/cacti/rra/dcn29481_traffic_in_19.rrd': No such file or directory When I turn on debug I get the following in the logs (I have added logging for poller.php): poller.log Waiting on 1/1 pollers.

I have also tried installing using the tgz from the cacti.net website with no success. I think the problem is being caused by one of the depenedencies, probably php. The bigest difference between the CentOS install and Fedora in reference to Cacti is the version of php. Centos as you know uses php4 and Fedora uses php5. And yes I have followed the documentation that resides on the CentOS wiki as well as the docs on the Cacti website. I have also tried running the poller as root with no success. Any help would be greatly appreciated. -- Matthew Martz CentOS Mirror Admin mdmartz(a)gflug.net
