Since this is a text mailing list it's better to insert the files into
the email. Many servers will strip out attachments so they
can't be seen.
I've pasted them below.
Before:
10.0.0.1
10.0.0.2
10.0.0.3
10.0.0.4
10.0.0.5
After:
10.0.0.1 localhost
10.0.0.2 remote host
10.0.0.3 No resolution availabe for 10.0.0.3
10.0.0.4 localhost
10.0.0.5 No resolution availabe for 10.0.0.5
So, basically you just want to append the name (or an error message)?
In pseudocode this would be
open in_file
open out_file
for line in in_file:
try:
name = gethostaddr(line.strip())
out_file.write(line + '\t' + name)
except herror:
out_file.write(line + '\t' + errrMsg)
close in_file
close out_file
delete in_file # or rename to .bak
rename out_file to in_file
Can you translate that to Python?
