dhcpd

Hi im trying to configure centos to run as a dhcpd daemon but it simply doesnt work I'm using the default configuration file from dhcdp (and tried multiple alternatives). problem is that pxe clients do not aquire dhcp addresses in the log i can see that there are 3 or 4 dhcp offers per boot atempt but no dhcp requests anyone? i'm going crazy here... .i've tryed 3 diferent machines (servers) and 4 or 5 diferent clients sometimes windows clients are able to catch the ip but only sometimes. maybe this is a route problem? the machine(s) was freshly installed with centos 4.3 please advise!

SCSI drive offline

I’m running centos 4.3 (2.6.9-22.ELsmp) on a box ,and running windows XP on vmware 5.5.1. I have 3 scsi disk on this server,sda for linux system,sdb for vmware disk,and sdc for other. Resently I found that something wrong with the second disk,the guest os windowsxp copying files from a samba server(another box) to it’s disk,and for some time,maybe 5hours,3or1hours, the kernel said that sdb is offline… then I reboot,everything is ok,no filesystem check. but this problem accours every a few hours when the windowsxp copying a lot of files to it’s disk. I’m not sure if it was the heavy load of the disk made this problem. then I run smartctl to see if it’s overheat,but result nothing,smartctl said the temperature is ok (27-29c). is it a hardware problem? cable? disk is dying? kernel problem?vmware problem? and here is the dmesg dump when this problem happening..

Copying user accounts (passwords) to another server
by Nigel Kendrick 29 Nov '06

29 Nov '06

Hi Folks, I am doing a server swap out tomorrow and wondered if there was a utility that will copy user account details and their current passwords from one server to another (both CentOS 4) - there's only about 15 to do so it's not a major issue. Thanks Nigel Kendrick

hostname setting
by MrKiwi 29 Nov '06

29 Nov '06

Can someone with far more knowledge than me help here? I have a co-worker with a question; " Where should i set the server's hostname? There seems to be multiple places and i don't understand the differences. 1. # hostname mailserver.mydomain.com 2. # echo "127.0.0.1 mailserver mailserver.mydomain.com">>/etc/hosts 3. # vi /etc/sysconfig/network, add "HOSTNAME=mailserver.mydomain.com" So far i think i understand that postfix likes to see the hostname in the hosts file, but things i have read imply that postfix is pretty clever at working it out from multiple places. Apache also seems to be clever, but the conf file recommends that you hard code the server name into the config. If you don't, where does apache look? If you set the hostname during an install, where is that written? If i use method 1 above ("hostname mailserver.mydomain.com") i seem to have to do that at every boot (or script it of course) whereas the edit to /etc/hosts or /etc/sysconfig/network would survive restarts. I have read the information in "man hostname" and understand that "hostname -f" gets its info from the hosts file, but where does the function "gethostname" get its info from? Finally - which method do you all use to set you hostname? " Thanks all, MrKiwi

Iptables front-end
by Jordi Espasa Clofent 29 Nov '06

29 Nov '06

Hi all, ¿What iptables do you use to manage iptables? ¿Or maybe not? Simply curiosity, so I'm coming from openSUSE and in that distro there is a YaST module front-end (YaST firewall). TIA. -- Jordi Espasa Clofent PGP id 0xC5ABA76A #http://pgp.mit.edu/ FSF Associate Member id 4281 #http://www.fsf.org/

Disable IPV6
by Tom Brown 29 Nov '06

29 Nov '06

Hi On a CentOS 4.x box how does one disable IPV6? Is adding "alias net-pf-10 off" to the end of modprobe.conf and a reboot still the 'standard' way of doing this ? thanks

by Jerry Geis 29 Nov '06

29 Nov '06

Gents, I am trying to do a "gcc -m32" on a x86_64 box. gcc -m32 /tmp/jj.c /usr/bin/ld: crt1.o: No such file: No such file or directory collect2: ld returned 1 exit status This is the error I get. I did a "yum install glib.i386" successfully. there is no "yum install glib-devel.i386". How can i get a "gcc -m32" compile on my x86_64? THanks, Jerry

29 Nov '06

Hi there.... Has anyone seen a tutorial around for a pptp server (on the same server as the firewall) for centos/rhel 4? I have been following a few general tutorials for POPTOP, but nothing seems to really work as of yet. Thanks!

kernel and iptables with l7-filter
by David Hrbáč 29 Nov '06

29 Nov '06

Hi, those who are interested in l7-filter on C4.4, here is the testing repo. http://homen.vsb.cz/~hrb33/el4/hrb/testing/i386/RPMS/repodata/ Kernels and iptables RPMS are compiled with l7-filter. Feel free to test and send the reports. Packages are not signed, not even with special release version. Should be fixed on final release. New release should also include IMQ, ESFQ. Iproute is the only package compiled with ESFQ for now. Regards. David Hrbáč
