RHEL7 Install/Use Freeradius




TigerVNC on RHEL7

From RHEL7/Centos7, chkconfig was removed, and replaced by systemctl, that combine with chkconfig and service, and powerful. But I found that have some issue when interactive with tigervnc, that maybe tigervnc issue, i use default rpm for “tigervnc-server-1.2.80”.

When you install the TigerVNC on RHEL7/Centos7, maybe work normal by  follow step:

[root@frank yum.repos.d]# yum install tigervnc-server.x86_64 
[root@frank yum.repos.d]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
[root@frank yum.repos.d]# vim /etc/systemd/system/vncserver@:1.service 
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i -geometry 1024x768"
[root@frank yum.repos.d]# systemctl disable firewalld.service

Compiling Wireshark 1.12

Same topic I had posted at stack overflow, that include more detail output:
Qt is not available error while compiling a wireshark 1.12

Now move it to my blog for review.
I have a issue on rhel6.3, and I download all qt47 rpm:

-rw-r--r--.  1 root root  4282888 Sep 22 06:32 qt47-4.7.1-3_15.el6.x86_64.rpm
