A NIC can have multiple IP addresses and this is easiest to do with ifconfig.
ifconfig eth0:0 10.0.0.12 netmask 255.255.0.0
To delete the alias:
ifconfig eth0:0 down
I loaded the development app on the mac.
I tried to configure glib-2.34.3, but it required gettext. So, I got gettext. The only problem I has was the file stpncpy.c had a weak_alias macro that allowed stpncpy.c to declare a function. However, since Mac already had that function, there was a problem. I had to define weak_alias in that file:
#define weak_alias(a,b) /* */
Of course, the right way to do this would be to check if stpncpy.c is defined. The test failed on bash. Everything else passed.
On to the build of glib2.
I had to define export LIBFFI_LIBS=-lffi and export LIBFFI-CFLAGS=-I/usr/include/ffi
Then, config did not put these values into the make file so I had to invoke make with “-e” option.
The package I wanted to compile needed pkg-config, so I went to http://www.freedesktop.org/wiki/Software/pkg-config to get it. I needed to put in the variables from /usr/local/lib/pkgconfig/glib-2.0.pc from Libs: and Cflags: as
GLIB_LIBS="-L/usr/local/lib -lglib-2.0 -lintl"
It often happens that after dd or win32image an ISO to a USB drive, it makes partitions much smaller than the drive itself. Here are some steps to wipe out those partitions and start over:
- Run an elevated command prompt (shift-right click run as adminstrator)
- Find your drive (look for size)
create partition primary
select partition 1
format fs=exFAT quick
Here is how to get Linux to talk to a APC UPS via USB port.
sudo apt-get install apcupsd
Set device to usb (Leave DEVICE blank)
set ISCONFIGURED to yes
sudo service apcupsd start
To remove the “windows 10” upgrade notification, uninstall KB3035583. Then hide the KB3035583 so it does not get installed again.
Here is a way to identify files that have duplicates.
find dir -type f -print0 | xargs -0 md5sum > filelist.txt sort filelist.txt > filesort.txt uniq -w 33 -D filesort.txt # more legible uniq -w 33 --all-repeated=separate filesort.txt # also --all-rep=sep works
This will show which files have duplicates. I saved the results in a file instead of piping everything so one can go back to filesort.txt and identify the other files which have the same md5.
Make sure you actually compare the files. Some files could possibly have the same md5sum without being the same. They will likely have a different size. It is possible for two files of the same size to have the same md5sum.For better positive hits, use sha256 (slower).
Here is how to analyze a kernel crash dump in CentOs
First, to install vmlinux with debugging symbols strings /var/crash/127.0.0.1-2013-06-22-18\:15\:01/vmcore | less Look for the kernel version. In this case: OSRELEASE=2.6.32-220.el6.x86_64 Go to http://debuginfo.centos.org/6/x86_64/ and download kernel-debuginfo-2.6.32-220.el6.x86_64.rpm and kernel-debuginfo-common-x86_64-2.6.32-220.el6.x86_64.rpm Install on target machine with rpm -ivh kernel-debuginfo-common-x86_64-2.6.32-220.el6.x86_64.rpm rpm -ivh kernel-debuginfo-2.6.32-220.el6.x86_64.rpm Finally, the crash dump analysis: crash /usr/lib/debug/lib/modules/2.6.32-220.el6.x86_64/vmlinux ./vmcore
Use the “bt” command to pull up a backtrace. It will tell you what program was running and what happened to cause the crash.
