hi all
not sure if this is the right forum but i got a redhat with nfs automounted. I want to use iozone to test the performance of the nfs. What I can't figure out is if the test is happening over the nfs or not. I am running this command:
./iozone -Rac -i 0 -i 1 -g 4G -b output.xls > logfile_may6
Does anyone have experience with this tool and can help me out?
Thanks
Dear all,
I don't know how I can figure this problem out.
I tried to execute iozone with clustered mode but it didn't work. It stalled after executing the last line (see below!)
What do you think the problem is?
Please let me know if you have similar experience to me.
Best regards,
Jeongsook.

Hello,
I'm looking for options/tools where I can get server performance counters for Linux OS (having Java application on it). For windows based platforms, we have PerfMon that provides this data. I'm looking for a similar tool for Linux platform java apps. Could you please help me in identifying the best options to get the performance related data like Perfmon?
Thanks,

Hi All,
I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:
0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl
But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.
But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test
Still nothing. if I run it as /usr/bin/perl script.pl it runs though
Thanks in advance.
Hi Forum,
I have a network printer (HP) running on 192.168.85.24 and I wish to install something that enables me to just shoot pdf och ps files directly to it from the command line, however, it has been hard finding something that describes how to make a bare bones setup like that, the most info I find talk about user interfaces, clicking menues opening web browsers etc, I want things incredibly simple, then they are more robust.
Do you have a tutorial on how to just get an HP-printer to accept ps och or pdf files from the command line?
I run Debian with LXDE and have contact with the printer. (I tested with ping.)
Another question I have is for this forum, do you have a search function? If I had had a search function I would have searched for an answer to the question before posting it.
Kind regards
Johnny
Hi,
I have been trying to get information on how to process the output of a tcl file (aodv and leach protocol using mannasim) which I got on my command line Iinterface. Actually, I don't even know the keywords to search as I am new to this and other minor attempts haven't yielded positive results., I know there is usually a trace file but I can't see any. All I see is on my command line.
I also observe that it took the space on the entire screen and I can't copy the output from the start ( I could only copy from node 19 out of 30 nodes) because of the huge number of output lines.
The last thing I havent been able to figure ou is whether temperature is equivalent to energy Iin mannasim as mannasim has only temperature and carbon dioxide?
Thanks
hi experts
I got a bit of problem with the below situation:
Code:
root@kvm_host1:/mnt/nfs# virt-manager &
[1] 4663
root@kvm_host1:/mnt/nfs# X11 connection rejected because of wrong authentication.
[1]+ Done virt-manager
root@kvm_host1:/mnt/nfs# su test
test@kvm_host1:/mnt/nfs$ virt-manager &
[1] 4679
As you can see, I ssh into my ubuntu host with user test, but during some nfs config I su into root, then try to launch virt-manager GUI via X11. Which obviously fails I guess since root wants to launch X11 session but I established the session as user test.
My question is this: Is there a way to stop this from happening? to allow my root to launch the GUI as well?
Thanks
Hi Forum members,
I'm interested to get the date on which particular command was ran.
I've below in my .bashrc
Code:
export HISTTIMEFORMAT="%d/%m/%y %T "
I ran history | grep "cp" | less
I get an output like:
Quote:
1288 27/05/15 09:12:55 sacct -j 767151 --format=elapsed,ncpus,state
27/05 is today's date. But I'm interested for the date, the above output was ran.
What am I missing?
Hello all, I am new to Linux (apparently) and am taking a intro course to the OS. My terminal does not support info or man for the cd command and I would like to know: If you won't find the cd command in either /bin or /usr/bin, or in any directory listed in the PATH setting. How is it executed then? (That is, if there is no cd executable, why doesn't this command cause a “command not found” error?)
Thanks for any help!
Hi,
Apologies if this is in the wrong forum, wasn't sure which was most appropriate...
I've built a Redhat 7 VM from an ISO and I've carried out various configuration on it and for some reason when I now run ip commands (for examnple 'ip addr show') I no longer get any output on screen.
Example...
[root@rhel-7-xx2 ~]# ip addr show
[root@rhel-7-xx2 ~]#
Version I'm using is:
Red Hat Enterprise Linux Server release 7.0 (Maipo)
I built another server and had the same problem and managed to fix it by yum updating all packages so it looks like a package needs to be updated but not sure which one.
If I pipe the output to a text file I can see the output okay in the file.
I have a ticket open with Redhat but it's taking a while to troubleshoot with them so thought I'd see if anyone else had seen this in the meantime...
Thanks
James
