hi,

  im currently downloading the 4.6 BSD iso images. does this mean that
if the date of the md5sum file in the server im downloading was modified
on or later than july 30 then the image might be compromised? or does
the trojan only affect the individual openssh packages at the ftp sites?

  i know its probably a stupid question but i want to have confirmation. 

ciao!
