Login Hangs After CentOS/RedHat Kernel Update

Published by admin-joel on 2015-06-15

June 15, 2015

A second incident of login getting hung after kernel update is found. The first incident was reported on Aug 2, 2014. As usual when users type in user name and password at the login window and hit login the login process gets frozen and cannot get to the desktop. It appeared to only affect tsch (using .cshrc) users.

The solution is to hit ctrl-c and then rm .history to get rid of the .history file. Note that if you do it from ssh, it might cause the host to reboot.

Canopus and Algol got updated over the weekend to kernel version 2.6.32-504.23.4.el6.x86_64. Hence it seems like it is only affecting these two hosts.

compile pgplot in 32bits

Published by admin-joel on 2015-06-09

Since we decided to compile the computing programs in 32 bits to ensure consistencies, pgplot should be compiled in 32 bit as well so that those programs can call it. The build notes are in

/usr/share/astro/psrchive/00READMECarleton

 

The compatibility libraries (with the yum commands) that I had to pull in (which Bruce had a copy):

yum install compat-libgfortran-41.i686
yum install libICE-devel.i686

yum install glibc-devel.i686

yum install zlibrary-devel.i686

yum install libpng-devel.i686

yum install xorg-x11-server-devel.i686

yum install compat-libstdc++-33.i686

yum install compat-libstdc++-296.i686

yum install libxcb-devel.i686

yum install libxcb-devel.i686

yum install zlib-devel.i686

yum install libX11-devel.i686

mingw64-pkg-config.x86_64

Published by admin-joel on 2015-06-09

I installed mingw64-pkg-config.x86_64

It seems like it need to pull in its sister package e2fsprogs before compiling dump by typing in the /root/ directory

$ git clone git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git

$./configure –enable-elf-shlibs

$ make

$ make check

$ make install

$ make install-libs

which puts the binary file in /usr/bin or /usr/local/…

then go to the dump source file, type
