A test app does a fork, creates children processes.
Is there a way to view the procTBL "ps" to be able to see that a
process is a "child" process?
I know you can see when a child has stopped, but the parent is still
running.. but is there a way to see if there are "running" children,
some attribute that denotes i'm a child?
Or, is there some attribute that denotes the process has running children?
I am using CentOS 6 and grub 0.97
1. Launched a Virtual Machine (VM) with CentOS 6. (This step is done.)
2. After the VM comes up, copy latest kernel and initrd from remote
server to /boot
through a script present at /etc/init.d/ (This step is done)
3. How to edit grub config file either by command or by script (but
not manually), to update
the new kernel and initrd so that next time it boots up with the
new kernel ?
Fedora 20 x86_64, gnome shell
I'm recording off my line input and it's coming in a bit hot so I'm using
the gnome-shell control to drop it from 100% to "unamplified". It stays as
long as the program runs but as soon as I close it (or when I reload the
program, haven't checked) it resets to 100%.
These are the only versions of Fedora I have handy...
I use enscript to print IETF docs off in 2up/duplex:
enscript -2r --margins=:::45 -DDuplex:true -P HP8600
Worked fine last fall, then stopped working when I installed F20; I
don't recall what I was running prior, I think F19. What stopped was
the Duplex feature. I put up with this for the past year, no 2-sided
printing. So I tried it on the F21 beta today, and still no duplex.
Then I remembered I have an Asus EE 4g Surf with F17 on it. I set up
the printer and this version DOES do duplex.
So some point, I think with F20 something changed, perhaps in hplip such
that the Duplex option is no longer working.
Any ideas on how to figure this out? Printing IETF docs nicely is not
so easy. They are exactly formated to page size, and you can't pay
around with that so easily. It took me a bit to figure out the margins
to get it to fit.
Oh, Libre office, Firefox, and Thunderbird all do duplex printing just
fine to the HP8600. There is a nice dialog to select 2-sided printing.
Ok, I recently installed the new to be release Fedora 21 on my server
(client been testing for months now). I have rsync setup to mirror some
Fedora sites (fedora, beta releases, updates, updates-testing, etc..)
that I mirror every day, usually every 4-6 depending on which script
runs. This has run flawelessly up until the server had F21. It would
mirror, delete and downloaded what was needed just fine.
Now, for some reason, everyday it looks like the mirrors are all deleted
and packages downlaoded from scratch. The only thing I can find that
seems related is when I do a yum update (client side mostly, and I have
the mirrored dir's mounted via nfs, as is same as when was on F20), it's
after that it seems the dir's get deleted. And I don't mean the dir
itself, but the contents of them.
For example, I have /rsync/fedora-test/ as my prerelease dir and all the
branches of F21 (release, updates, updates-testing, rpmfusion stuff) are
in there. All of the dir names are listed as always, but the sub's are
removed and then redownloaded again. I have tried 2 different mirrors
and both happen the same.
It's like when yum tries to upgrade (and it may be when I do a yum clean
all), then something happens to the dir's (and it may not be exactly
that, but right after) then next time rsync checks, it downloads it all
from scratch again. I can say, up to the point of it downloading again,
before that, when rsync checks the mirrors, it only deletes/downloads
what was changed, not the whole thing.
I don't get it nor can find what is happening. Wondering if the
harddrive itself is going bad somehow, as the rsync/mirror stuff is on
sep HD and mounted that way from install?
Any thoughts on what to look for, or any other details to show you or
give you that might help decide what to do or how to do it?

Is anyone successfully running NFS over RDMA on Fedora 20+?
I've edited /etc/sysconfig/nfs and set the the following config paramter.
Upon restarting the nfs server I get the following:
modprobe: FATAL: Module svcrdma not found
/usr/libexec/nfs-utils/scripts/nfs-server.postconfig: line 12: echo:
write error: Protocol not supported
So it looks like the kernel module svcrdma is missing and the last
kernel to have it was 3.11.10-301.fc20. The postconfig script belongs to
Is svcrdma intentionally not built in the current kernels or has it been
replaced by something else?
Query regarding Booting Linux VM (Virtual Machine) from a network server
I am interested to boot my VM with PXE BOOT through command line (not
After doing google I found many docs on this topic but all explains
about server side configuration I hardly find any doc which explains
client side configuration that needs to be done for VM .
What configurations / steps should I follow on the client side so
that my VM will be enabled for NET boot ?
Please remember I am interested to do everything on command line. No GUI.
I would like to boot my VM with Centos / Fedora linux. Suppose
server side configuration is done. Now what should I do on client
side (through command line, no GUI), so that VM will come up with NET
boot shell prompt ? after that it will download CENTOS / Fedora image

That's good, at least F20 is on 3.17+ now.

Thanks for that. I'll enable it any give it a go anyway. It's not a
mission critical system, just a home network so it's worth the risk.
