Hi List,

I wrote a simple script that import a file list of hosts and try to  
connect.  
Before the end of the file the script exits with this error:

/usr/lib/ruby/1.8/net/protocol.rb:133:in `sysread’: end of file reached  
(EOFError)

I using this code to import list:

file = File.new(list,“r”)  
begin  
while (line = file.gets)  
line.chomp!  
iplist.push line  
end  
rescue EOFError  
f.close  
end

Can you help me please?  
Thank you very much

Al

It looks like the error is in the part of the script where you’re  
connecting to hosts, since it’s in the net code.
