Truncating leading zeros in strings
I am new to R. I thing this will be simple, but I don't yet know my way
around.
I am generating character strings from the system clock that represent
integers, and I want to convert them to integer values. Strtoi works
well, except when there are leading zeros on the string. Could anyone
suggest a way to remove those leading zeros?
Thanks
Paul

OpenSSH ControlAllowUsers, et al Patch
Attached (and inline) is a patch to add the following config options:
ControlBindMask
ControlAllowUsers
ControlAllowGroups
ControlDenyUsers
ControlDenyGroups
It pulls the peer credential check from client_process_control() in ssh.c,
and expounds upon it in a new function, client_control_grant().
Supplemental groups are not checked in this patch. I didn't feel comfortable

resource starvation against passwd(1)
Standard apology if old...
This demonstrates a resource starvation attack on the
setuid root passwd(1) program. In the case I tested it was the
Red Hat Linux passwd-0.50-7 program without shadowing.

#include <sys/time.h>

Slow write times to gluster disk
Hi,
We noticed a dramatic slowness when writing to a gluster disk when
compared to writing to an NFS disk. Specifically when using dd (data
duplicator) to write a 4.3 GB file of zeros:
* on NFS disk (/home): 9.5 Gb/s
* on gluster disk (/gdata): 508 Mb/s
The gluser disk is 2 bricks joined together, no replication or anything
else. The hardware is (literally) the same:
* one server with

Re: virtual drive performance
Hi again,
just today an issue I've thought to be resolved popped up again. We backup
the machine by doing:
virsh snapshot-create-as --domain domain --name backup --no-metadata
--atomic --disk-only --diskspec hda,snapshot=external
# backup hda.qcow2
virsh blockcommit domain hda --active --pivot
Every now and then this process fails with the following error message:

Re: 答复: virtual drive performance
Just a little catch-up. This time I was able to resolve the issue by doing:
virsh blockjob domain hda --abort
virsh blockcommit domain hda --active --pivot
Last time I had to shut down the virtual machine and do this while being
offline.
Thanks Wang for your valuable input. As far as the memory goes, there's
plenty of head room:

No increased throughput with SMB Multichannel and two NICs
Hello,
I'm running Samba 4.4.5 with enabled SMB Multichannel. The Linux server
has two 1GBit/s NICs and for testing purposes I've shared a tmpfs
mountpoint with 2GiB and ~2GiB large test-file.
My Windows 10 host has one dual-port 1GBit/s NIC, and if both interfaces
are enabled, Get-SmbMultichannelConnection lists active multichannel
connections to my Linux SMB server.

How to define class type hierarchy of speeds?
Hi
I''m very very new to tc iproute etc and have read the LARTC howto.
What I want to do is create some "master" classes of bandwidth limit and
below that per ip address which "inherits" from this master class.
Example:
one queue for 128Kbps
other queue for 256Kbps
What I want now is that for example in "class" 128Kbps the ip
10.0.0.5, 10.0.0.8 etc. goes
