General :: Difference Between Xtime And Gettimeofday()
Oct 24, 2010
why there is a difference in the time shown by xtime and gettimeofday ? From what I have read I understand that xtime is not frequently updated and gettimeofday is more precise than xtime.
i am trying to print the time in ms using the gettimeofday function, but on execution the shell gives: Segmentation fault (core dumped) error and leaves the program.. here is the code:
Whenever I enable gettimeofday in my code, previous working sendto(raw_eth, buffer, ...)
stopped working and Error: Bad file descriptor. the only thing I'm sure is it's not name pollution. Since all the variable defined in main() works if I make the wrap of gettimeofday an empty function.
The 3.4G is correct because we have removed all non essential file but free space reported by df is not consistent with the actual free space that should be there.
I need to know the exact difference between SCP and SSH can somebody explain please as i am confused as both seem to do the same thing if so let me know what the difference is.

I created 2 virtual machines with VMware Workstation 7. They have identical hardwares. One guest is CentOS 5.6, another is Mandriva 2011. When I try to mount the cdrom in guest OS, in CentOS, I should execute
mount /dev/hdc /path/to/mount
in Mandriva, I should execute
mount /dev/sr0 /path/to/mount
I also remebered in some other Linux variant, I had to use
mount /dev/cdrom /path/to/mount
What's the difference between hdc, sr0 or cdrom? Is there a consistent way to mount cdrom in all Linux variants?

sometimes when I install Centos5 on separate machines, it boots with el5 kernel on one and other with el5PAE. Server models are almost identical to one another. such as identical motherboard, identical cpu, difference in Amount of RAM, different Harddrive manufacturer. I'm assuming this is hardware dependant but what is the difference between these two?
