e1000 gig nic howto?
We have a 10Gbps connection to our server so I need to be able to create VMs using the faster e1000 nics instead of the default Realtek 100Mbps ones but I''m not sure how to go about it.
Is there a walkthrough or "howto" or can someone point me at some simple instructions?
I''m using xen-3.0.3-105.el5_5.5 and Centos 5.5 kernel 2.6.18-194.32.1.el5.centos.plusxen

rsync question
I'm trying to rsync a 8TB data folder containing squillions of small files and it's taking forever (i.e. weeks) to get anywhere.
I'm assuming the slow bit is check-summing everything with a single CPU (even though it's on a 12-core server ;-( )
Is it possible to do something simple like scp the whole dir in one go so they're duplicates in the first instance, then get rsync to

nic bonding
I've just setup nic bonding on our server (DL585-G7 running Centos 5.5 x86_64) as detailed on the wiki: http://wiki.centos.org/TipsAndTricks/BondingInterfaces and all seems fine but from other "howto's" I've seen on the web, they're should be a /proc/net/bond0/info
As far as I can see, I don't have one and I'm not sure if it should be there or its absence is a

mount NFS share over specific nic?
I have a new server with multiple nics running Centos 6.2 and I'd like to force all NFS traffic over one nic.
We're using FreeNAS to dish out NFS shares and I have different IPs on my 2 nics but how can I get the server to mount the share over one particular nic?
Or is there a better way to do it?
Thanx,

~/.forward file?
Hi all,
I'm just poking thru our previous sysadmin's user adding script and saw reference to a ~/.forward file containing the users email address.
Any idea what it might be for?
It's a tricky one to Google ;-)

NIC bonding - missing eth0?
I have nic bonding (mode=802.3ad) setup on 2 servers, both running Centos 5.5
In the "Active Aggregator Info", on one reports 4 ports - which is correct - but the other only reports 3 ports.
It''s always eth0 that shows a different aggregator ID. Changing the cables around so it hits a different port on the switch makes no difference. The switch is correctly configured for the

windbind and AD authentication - UPPER CASE usernames?
We're looking at using windbind and AD for our user account details but have run into a small snag. All user accounts in AD are upper case but our linux accounts are lower-case.
Is there a simple solution we've overlooked?
We really don't want to have to hack this...

preventing symlinks?
This may be more of a general linux question but is there a simple way of preventing users from creating symlinks to or from certain directories?
I have a /scratch dir that's a single 27TB volume and I don't want users linking their home dirs as there's a chance it will screw up our external backups.
Is this a job for SELinux?
Any ideas?
Thanx,

LVM overhead? Does it cripple I/O?
For a high-performance system (64-cores, 512GB RAM, 5TB local disk, 110TB NFS-mounted storage) is there any advantage of dropping lvm and mounting partitions directly?
We're not planning on changing partition sizes, but if we did we'd probably do a full rebuild.
Has anyone done performance testing to show that lvm isn't crippling I/O?
Thanx,

not using LVM for Linux VM guests?
I came across an old post comment yesterday (from http://echenh.blogspot.com/2010/04/how-to-extend-lvm-on-vmware-guest-os.html ) discussing the "hack" of LVM on Linux VM guests and whether it's better not to use it to simplify disk management.
I've re-posted the comment below, does it sound reasonable? Is it better to not use LVM on Linux VM guests?

reading vdump files?
I have a lot of data in some vdump files backed up from a Tru64 system that I now need to recover to a Centos server.
We no longer have any servers running Tru64, is there any way to extract/convert them on a "standard" linux system?
Ideally converting in bulk to a tar would do.
Any ideas?

Xen on Centos 5.5 vs 5.3 and stability issues
I've recently upgraded a Centos 5.3 machine to Centos 5.5. The
hardware isn't HVM capabile so I'm only running para-virt guests.
Using a vanilla i386 kernel boots without, but the newer kernel-xen
locks up the Dom0 after a couple of minute. I'm only booting into
single user mode for these tests so no VMs are active.

Documentation of R Version 2 binary file format (.rda)
Is there a document available that gives a clear description
of the layout of data in a version 2 .RDA file. I have a free
program (http://www.vsn-intl.com/genstat/downloads/datald.htm)
(Windows/Linux/Sun MOTIF exes available) that reads and writes
a wide range of file formats, and have been requested by my users
to add R to this. It already does S+.

Repair Filesystem prompt , after inode has illegal blocks
hi All,
A fault on our SAN dropped us down to a read-only filesystem and after reboot,
we have an "Unexpected Inconsistency" and I am being instructed by the boot to run fsck manually
without -a or -p (this was after I think processing around 15% of the filesystem)
The specific message is "inode 27344909 has illegal blocks"

IPTables GUIs
Hi,
This is semi-OT, but is Centos-related.
I'm looking for an IPTables GUI to help us with our expanding
network configuration. I know there's plenty out there, but most of
them seem to manage the firewall on the computer on which they run, or
only handle one firewall at a time. I need one that can easily manage
multiple firewalls from some sort of central location/repository, i.e.
