Some effective tools tips on Mac platform

Transfer to Mac platform for many years, some effective tools are very useful at normal work. Some tools can transparent to covert to Mac platform, e.g SecureCRT, UltraEdit. But some of better new tools need to be adapted, so I wrote the article and discussed tips of them. That can help some people easy and effective to use the tools. Certainly, please support genuine software 🙂


I like login to linux server by terminal of MacOS, but that tool function very less and couldn’t auto generate logg, so I found another good free tool – Iterm2, that is good terminal console in MacOS. Let me show some tips on Iterm2.

Auto check share memory utilization for IOX by Python


In some scenario, we need to monitor some data in router/switch by automation. This article will show example that how to check share memory utilization. And you can easy to change the script base on your requirement/scenario.

After installed Centos 6.7 for CISCO WAE, I found python version is 2.6 that is much older, and I need ansible1.9, but Centos default upgrade to ansible2.2… in order to easy management ansible1.9 that is python package, I plan to install PIP. From official website, suggest not use 2.6 under pip, so I need to upgrade python to 2.7 too.

But I found WAE use 2.6 after I succeed upgrade python to 2.7…Summarized the totally steps that will help me review in future.

2. Install python 2.7.9

[root@wae ~]# wget
[root@wae ~]# mv Python-2.7.9.tgz /opt/
[root@wae ~]# cd /opt/
[root@wae opt]# tar -xvf Python-2.7.9.tgz 
[root@wae opt]# cd Python-2.7.9
[root@wae Python-2.7.9]# ./configure --prefix=/usr/local/python2.7
[root@wae Python-2.7.9]# make
