>Description:
some how a URL (easymoney.com) was able to change my default webpage to there's.  I did a query on there domain name, and found a entry in there dns zone file.  One of the entry names is *.exitmoney.com.  I wanted to see if I could establish a connection using that hostname.  

Here is what I got:

bash-2.03$ telnet 
telnet> o
(to) *.exitmoney.com
Segmentation fault (core dumped)

Also the same using FTP server (Version 6.00LS) 

bash-2.03$ ftp
ftp> o
(to) *.exitmoney.com
Segmentation fault (core dumped)
bash-2.03$ 

-rw-------    1 liveevil  liveevil   380928 Jun  7 12:41 telnet.core
-rw-------    1 liveevil  liveevil   454656 Jun  7 12:42 ftp.core


>How-To-Repeat:
bash-2.03$ telnet 
telnet> o
(to) *.exitmoney.com
Segmentation fault (core dumped)

Also the same using FTP server (Version 6.00LS) 

bash-2.03$ ftp
ftp> o
(to) *.exitmoney.com
Segmentation fault (core dumped)
bash-2.03$ 

>Fix:
It seems like both ftp and telnet have trouble with input from host names with "*"'s in them.  I have also try to reproduce the same results using ping, nslookup and traceroute without any luck.  I do not know how to fix this problem.
