I see one mention in the forums of someone using the CentOS5Web AMI, but I can't find anything about its provenance.

Bug in dhclient-script for ntp.conf in Centos 5?
by Stephen Harris 17 Jun '08

17 Jun '08

I dunno if this is upstream or not since I don't have any RHEL5 % rpm -qf /sbin/dhclient-script dhclient-3.0.5-7.el5 This section of code appears to have a bug (around line 411) elif [ -n "$new_ntp_servers" ] && [ -e /etc/ntp.conf ]; then save_previous /etc/ntp.conf /bin/egrep -v '(^[\ \ ]*(server|fudge))|(generated by /sbin/dhclient-script)'< /etc/ntp.conf.predhclient > /etc/ntp.conf echo '# servers generated by /sbin/dhclient-script' >> /etc/ntp.conf localClocks=(`/bin/egrep '^[\ \ ]*server[\ \ ]+127\.127' /etc/ntp.conf.predhclient | while read s addr rest; do echo $addr; done`) localClockFudge="`/bin/egrep '^[\ \ ]*fudge[\ \ ]+127\.127' /etc/ntp.conf.predhclient`"; for s in $new_ntp_servers ${localClocks[@]}; do echo 'server '$s >> /etc/ntp.conf; done echo "$localClockFudge" >> /etc/ntp.conf; if [ -x /usr/bin/diff ] && /usr/bin/diff -q /etc/ntp.conf /etc/ntp.conf.predhclient >/dev/null 2>&1; then : ; else /sbin/service ntpd condrestart >/dev/null 2>&1 fi; fi fi; The problem is that if there are no "fudge' lines in the existing ntp.conf then localClockFudge will be empty, and this will cause a blank line to be appended to the end of the new ntp.conf; diff will then think the file has changed and so ntpd will be restarted. Over time a large number of blank lines will be prepended to the ntp.conf because of the initial egrep statement. -- rgds Stephen

Semaphore setup on database???
by mcclnx mcc 16 Jun '08

16 Jun '08

we are tried setup CENTOS 4.6 with Informix Dynamic server version 10 UC8 on DELL 6800. The problem we have is while doing bdatabase backup (ontape), we have error happen. I guess the error come from "semaphoe". server semaphore are: # sysctl -a|grep sem kernel.sem = 250 32000 128 128 # sysctl -a|grep shm vm.hugetlb_shm_group = 0 kernel.shmmni = 4096 kernel.shmall = 4194304 kernel.shmmax = 2147483648 Does anyone has ideal what semaphore should setup in Informix?

RE: Re: [CentOS] extremely slow network connection
by Tony Wicks 16 Jun '08

16 Jun '08

The computer is on a local switch together with an older computer, which in turn communicates well at 25 MB/s with all the rest of the world. At Dell's they propose a hardware support, however not for that model. Nevertheless they support officially CentOS. That's why I asked whether anyone had encoutered the same problem already, and could perhaps provide a solution. Yours, Peter I would recommend looking at your network speed/duplex negotiation with your switch. I suspect your switch may be full duplex and your network card half or vice versa. Try forcing your network card to various speed/duplex settings (and your switch if it is a decent managed unit) and re-try your testing. This is the most common cause of network performance issues. cheers

booting usb stick
by Jerry Geis 16 Jun '08

16 Jun '08

Hi all, I have been trying to get a usb stick 8G to boot centos. I am as far a it boots and hangs at "Switching to new root". I take the same USB stick and put it another PC and it boots fine. What might I look for as to why the machine hangs at switching to new root? Of course the machines are different. The one that does not boot is an ebox 2300sx and the one that does boot is an amd 4800+ with all disks unplugged except the USB stick. I am sooooo close. Jerry

Re: Re: [CentOS] extremely slow network connection

Dear Hendrik, Dag and Wealid, thank you for the replies; to be more specific, here is some more info: its a DELL Optiplex 755, with a 2 Gb/s onboard card. I did not write this because the same happens with an additional, elder 3Com card and Fedora 9, with a 2.6.25 kernel. Monitor and SATA disk work fine. The computer is on a local switch together with an older computer, which in turn communicates well at 25 MB/s with all the rest of the world. At Dell's they propose a hardware support, however not for that model. Nevertheless they support officially CentOS.
