Messing around with iptables
Hello all, I am messing around with iptables, trying to learn how it works so that I can build my self a router/firewall and mabey a VPN. Anyway I tried to use a command on my Desktop CentOS3 machine. "iptables -A INPUT -s 127.0.0.1 -p icmp -j DROP" now the command seems to have went through because I didn't get any errors, but when I go to ping 127.0.0.1 I am getting a response

NFS with UCARP vs. GlusterFS mount question
Morning Folks, should I prefer NFS with UCARP or native GlusterFS mounts for serving the system images to XCP? Which one performes better over 1G network links? NFS is probaby easier to setup due to existing tools like rpcinfo and showmount, both are used inside the storage container code, and there is some code for NFS, not for GlusterFS, except I write one. UCARP has the disadvantage that

CTDB: Clustered NFS, reboot, requires me to exportfs -r(a)
Hi Samba, I hope you are doing well. I run a cifs / nfs CTDB clustered NAS solution, and I find that when I reboot any of the nodes in the cluster, I must re-export the nfs mounts so they show up properly. Perhaps this is a general linux nfs bug and I am barking up the wrong tree, but I haven't found any problem / solution mentioning this as of yet besides my own known workaround

NFS issue with ZFS
I have Solaris 10 U7 that is exporting ZFS filesytem. The client is Solaris 9 U7. I can mount the filesytem just fine but I am unable to write to it. showmount -e shows my mount is set for everyone. the dfstab file has option rw set. So what gives?

I''m using shorewall 2.0.x at home as an Internet gateway for family. However my brother always plays online games overnight, so my parents asked whether I can do something on the gateway to control the time of accessing the Internet. I planned to put a script on crontab to schedule which it will execute say at 12:00 night daily, the script will execute a command will deny my brother

disabling showmount -e behaviour
I must admit that this question originates in the context of Sun''s Storage 7210 product, which impose additional restrictions on the kind of knobs I can turn. But here''s the question: suppose I have an installation where ZFS is the storage for user home directories. Since I need quotas, each directory gets to be its own filesystem. Since I also need these homes to be accessible

NFS question (and Best Practices)
I saw in another post that a best practices doc will be coming, but I figured I would try to get this working. I''m trying to understand why zfs uses so many "zfs create" so I can use it better. What makes sense is that each zfs fs can have it''s own options (compression, nfs, atime, quota, etc). I really love this because it is so tuneable -- compression on these

glusterfs over rdma ... not.
OK - finished some tests over tcp and ironed out a lot of problems. rdma is next; should be snap now.... [I must admit that this is my 1st foray into the land of IB, so some of the following may be obvious to a non-naive admin..] except that while I can create and start the volume with rdma as transport: ================================== root at pbs3:~ 622 $ gluster volume info glrdma

NFSv4 on CentOS 5.5
Hi, What is the magic juju that I have to put in /etc/sysconfig/autofs to get autofs to default to using NFSv4, rather than NFSv3, for mounting file systems? I don't want to place these flags into the automount maps themselves because we have a varied network with Sun, CentOS, RedHat and Macintosh systems, and the flags that have to get added to automount maps (which we distribute centrally

Disabling NFS
Howdy, With 3.1.3 the option was added to disable the builtin Gluster NFS. Does that mean that the following scenario should work: 1. Disable Gluster NFS "gluster volume set <VOLUME> nfs.disable on" 2. Restart the gluster servers for good measure 3. On one of the gluster servers, mount the volume using the gluster fuse client: mkdir /export/users # In /etc/fstab add

Dropping established connections
Hello, I have searched the list but couldn''t find the right answer. I want to drop an established DNAT connection but could not manage it yet. Someone earlier said to bring down the public interfaces, stop shorewall, bring up the public interface and then start shorewall again but this won''t work. I also saw a message from Tom that someone then should unload all iptables
