Re: [CentOS] Routing issue

I'm mostly sure that if you mark the *connection* to the FTP server, the related data will follow its path. Again, multipath routing is complex, and Shorewall will do it properly. At the very least, I recommend building a working configuration with Shorewall and then reading the rules that it compiles to understand why it handles routing the way that it does.

Cannot get kvm guests to connect to network
by James B. Byrne 11 Oct '12

11 Oct '12

I installed a new CentOS-6.3 kvm guest on a recently provisioned kvm host also running CentOS-6.3. This guest will not connect to the network and the host cannot connect to it via its public IP address. I had previously installed a guest system on thst same kvm host using the same ISO and that system connects to the network without problem. I next created a third guest isntance and this too does not connect with either the kvm host or the gateway. I have installed litterally dozens of kvm guests this past year and I have never encountered this situation. Has anyone else? Does anyone have any idea what might be going on? ip addr 1: lo <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 52:54:00:a0:26:47 brd ff:ff:ff:ff:ff:ff inet 216.185.71.243/24 brd 216.185.71.255 scope global eth0 inet6 fe80::5054:ff:fea0:2647/64 scope link vaslid_lft forever preferred_lft forever ip route 216.185.71.0/24 dev eth0 proto kernel scope link scr 216.185.71.243 169.254.0.0/16 dev eth0 scope link metric 1002 default via 216.185.71.1 dev eth0 netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 216.185.71.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 0 0 0 eth0 default 216.185.71.1 0.0.0.0 UG 0 0 0 eth0 service iptables stop . . . ping 216.185.71.1 PING 216.185.71.1 (216.185.71.1) 56(84) bytes of data. >From 216.185.71.243 icmp_seq=2 Destination Host Unreachable >From 216.185.71.243 icmp_seq=3 Destination Host Unreachable >From 216.185.71.243 icmp_seq=4 Destination Host Unreachable ^C -- *** E-Mail is NOT a SECURE channel *** James B.

Hostname
by Phil Dobbin 11 Oct '12

11 Oct '12

Hi, all. A very basic question but I'm wondering if anyone could give me a definitive answer. I recently installed CentOS 6.3 x86_64 on a Dell Poweredge 1850 (minimal desktop) & after setting the hostname during the install, when bringing up a terminal prompt, I'm still getting `localhost.localdomain` instead of the hostname I set during install (interestingly enough both parted & fdisk both show the correct hostname). After Googling the subject somewhat, it seems to be no definitive, correct way that everybody agreed upon. I'm away from my CentOS boxes for the morning (including the one in question) but on my Fedora 17 laptop, I notice that the given hostname is set in `/etc/sysconfig/network` but in `/etc/hosts`, it's `localhost.localdomain` & `localhost`. If I set my errant CentOS box the same way (all the others I have are OK), will this do the trick? Sorry for the basicness of the question but I'll be disabling the screen capabilities of the server this afternoon & putting her in situ & would like to get it right. Any help appreciated, Cheers, Phil... -- currently (ab)using CentOS 6.3, Debian Squeeze, Fedora Beefy, OS X Snow Leopard, Ubuntu Precise

Quota system over NFS
by Dave Ulrick 11 Oct '12

11 Oct '12

I've been trying to implement the quota system for a Linux cluster. I'm trying it out on a mini-cluster of 4 CentOS 6.3 VMs. I've named them: lion-login lion-sn1 lion-cn01 lion-cn02 All nodes are on the virtual subnet 192.168.56.0/24. lion-sn1 (storage node 1) is the NFS server and the other three nodes are the NFS clients. /etc/exports on lion-sn1: /home 192.168.56.0/24(rw) /etc/fstab on the other nodes: lion-sn1:/home /home nfs defaults,usrquota 0 2 User quotas are enabled on /home. rpc.rquotad is running on all 4 nodes. I'm having two problems: 1. I've confirmed that /etc/init.d/halt is running 'quotaoff -aug' before the file systems are unmounted but the shutdown of lion-sn1 is usually delayed for half a minute because a process is supposedly using /home. Any suggestions on how I could troubleshoot this? 2. Quotas work fine on lion-sn1 (the NFS server). Here's what happens when I copy several large ISOs into a user's home directory: 2. Quotas work fine on lion-sn1 (the NFS server). Here's what happens when I copy several large ISOs into a user's home directory who's logged onto that server: $ quota Disk quotas for user ulrick (uid 1000): Filesystem blocks quota limit grace files quota limit grace /dev/sdc1 68896 921600 1048576 3147 0 0 $ cp -v /mnt/home/images/CentOS-6.* . `/mnt/home/images/CentOS-6.2-i386-netinstall.iso' -> `./CentOS-6.2-i386-netinstall.iso' `/mnt/home/images/CentOS-6.3-i386-bin-DVD1.iso' -> `./CentOS-6.3-i386-bin-DVD1.iso' sdc1: warning, user block quota exceeded. sdc1: write failed, user block limit reached. cp: writing `./CentOS-6.3-i386-bin-DVD1.iso': Disk quota exceeded `/mnt/home/images/CentOS-6.3-x86_64-bin-DVD1.iso' -> `./CentOS-6.3-x86_64-bin-DVD1.iso' cp: writing `./CentOS-6.3-x86_64-bin-DVD1.iso': Disk quota exceeded $ quota Disk quotas for user ulrick (uid 1000): Filesystem blocks quota limit grace files quota limit grace /dev/sdc1 1048576* 921600 1048576 7days 3150 0 0 On the NFS client nodes, the attempt to use space beyond the hard quota limit is prevented but no warning is given for exceeding the soft limit, and the message issued for the hard limit excession is 'Input/output error' rather than 'Disk quota exceeded'.

Any suggestions on how I might resolve this issue? Thanks, Dave -- Dave Ulrick d-ulrick(a)comcast.net

Perl - strict.pm not found
by John Horne 11 Oct '12

11 Oct '12

Hello, I installed the ClamAV package onto a CentOS 6.3 server using yum. I then modified the /etc/freshclam.conf file to run a perl script whenever the ClamAV databases were updated: OnUpdateExecute /usr/local/bin/xymon_event ... The 'xymon_event' command is used on several servers, and generally works with no problems. However, on this server when the /etc/cron.daily/freshclam script runs in the early morning, I get sent an email error message: ===================================== /etc/cron.daily/freshclam: Can't locate strict.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/bin/xymon_event line 15. BEGIN failed--compilation aborted at /usr/local/bin/xymon_event line 15. ===================================== The problem is that 'strict.pm' is located in /usr/share/perl5 (as it is on our other servers), and /usr/share/perl5 is specified in @INC. So I am a bit lost as to why perl seems to think that strict.pm cannot be found. Anyone any ideas? We run ClamAV, with the freshclam cron job and xymon_event, on other servers (albeit CentOS 5.8) with no problems. Thanks, John. -- John Horne Tel: +44 (0)1752 587287 Plymouth University, UK Fax: +44 (0)1752 587001
