I've been working in a program in BASH and would like to measure its efficiency in different machines. Of course I am able to display the date at the beginning and at the end of its execution, but I'd rather use some sort of timer function to measure in seconds its speed. Is there any timer function available through command line?

I'm implementing a TCP protocol. TCP implementation requires to send packets continuously and if the receiver doesnt respond after a particular interval of time it should resend the packet again. I need some method to implement a timer expiry function. How can I implement it? Should i implement threads (If yes can you please give a sample)? or is there any better method? I'm implementing it in a Unix system.

I decided on a whim to pursue certifications in other operating systems (currently 70-620 and 70-290 certified with Microsoft) and bought a book on Fedora 10 and installed it on my extra PC. First issue I ran into was that due to my graphics card being an ATI I needed to run in text mode (based off posts on these forums) then once I finally got everything under control and installed, it loads directly into Command Prompt (you folks call it GRUB right?) I can log in as root but I can't do anything this way.It won't even allow me to do things like accept the end user license agreement or create new users or see the GUI.

View 3 Replies View RelatedI'm experiencing a peculiar problem with Fedora 12. There is a ten-second delay when various command-line applications (e.g. ssh, wget) connect to remote machines for the first time. The delay is also seen when the remote machine name does not exist.Subsequent connections to the same remote machine are immediate.This isn't a DNS delay - the host and dig commands return immediately, for both existing and non-existant hostnames. It's not a reverse DNS lookup by the remote machine either: other Fedora 10 machines do not experience this delay and neither did my two Fedora 12 machines when they were running Fedora 10.
time this was something to do with nscd, the name service caching daemon. Stopping nscd changes the delay to five seconds, but subsequent connections are no longer immediate - there is again a 5 second delay. This implies that nscd is caching the names correctly.The delays are always precisely 10 seconds, or 5 seconds when nscd is not running. I have confirmed this with the time command. There appears to be no odd network traffic (tested with tcpdump) and nscd appears to be running normally. I've confirmed this with a Fedora 12 live CD as well - nscd is not started at boot, but once started, the machine behaves in exactly the way described above.
with that said i burned fedora 8, 10, and 11 checked the sha1 verified everything was fine i had originally installed fedora 8 on an old pc i had from windows XP without any problems messed with it some, upgraded to 10 again no problems. tired to update 11 got a message about ext3 not found ext4 not found, re installed 10 the loader loads up now i have a blank screen with a cursor it the left hand corner
again i had 10 installed fine prior to all this can any one point me in the right direction to solve this issue or am i way over my head trying to figure this stuff out. i have spent 3 days searching these forums.
i'm just not quite sure what i need to do. oh, i tried to install 8 again and it wouldn't take either. i think the 10 problem has something to do with the graphic driver it's a geforce 7400 nvidia and something to do with the grub, but like i said i get a blinking cursor and not quite sure how to access the grub or command line.

View 9 Replies View RelatedI hosed my installation of F14 by installing from some "experimental" repositories. Now I only get XDM at startup and an xterm on login. This would be fine if I could use yum to do some updates, but I have no network connection. I have been over the man page for nmcli dozens of times and none of the options there seems to start anything. I have also tried starting dhclient or using:
ifconfig eth0 up Nothing. So, is there a reliable way I can just connect to the network? This shouldn't be so hard.
