On one of my servers running CentOS 6 I had iptraf not displaying the boxes in dialogues correctly.  It’s usually fixed by updating the session configuration on putty to translate to utf-8 but in this case that did not work.
While the system is a clone from another machine where it works well (puppet confirms) all I had to do is create an alias in my ./bashrc for iptraf to NCURSES_NO_UTF8_ACS=1  iptraf as such :
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
alias iftop='NCURSES_NO_UTF8_ACS=1 iftop'
alias iptraf='NCURSES_NO_UTF8_ACS=1 iptraf'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
As you can deduce the same issue and solution happened with iftop. 🙂
Oh the result :
