NetworkManager modifies /etc/hosts

There is an annoying bug (or feature depends on point of view) every restart/reconnect managed by NetworkManager, restore the original /etc/hosts loaded on startup. I’ve made a 3 line script inspired by visudo to manual edit the hosts file and prevent the other unexpected modifies:

File like (with +x attribute): /usr/sbin/vihosts

sudo chattr -i /etc/hosts
sudo vim /etc/hosts
sudo chattr +i /etc/hosts

Citrix – ICAClient issue on Linux REHL6

Another stupid Citrix ICAClient issue on Redhat linux:

[leo@thinkleo2 ~]$ /usr/lib/ICAClient/wfcmgr -icaroot /usr/lib/ICAClient
Warning: Missing charsets in String to FontSet conversion
Warning: Missing charsets in String to FontSet conversion
Warning: Unable to load any usable fontset
Error: Aborting: no fontset found

Solution 1 force language C (my favourite for any lang problems):

[leo@thinkleo2 ~]$ export LANG=C

Solution 2 remove charset cjkuni:

[leo@thinkleo2 ~]$ sudo yum remove cjkuni*
