Hi all, I updated nessus today, did a nessus-update-plugin as well, restarted nessusd manually (as I suffer from bug #1284 as well).
to my amazement nessus cannot identify an (my) smtp server anymore (which otherwise runs fine). It reports an unknown service on port 25. I watched the smtp's log (exim) and had repeatedly lines in it starting with: SMTP protocol violation: synchronization error (next input sent too soon): rejected "HELO example.com" H=[...] same lines with "EHLO there" "GET / ..." a.s.o. as if (my interpretation without checking any code) find_services is faulty in that it sends too many lines without waiting for replies or sending CRLF as NL instead of LF only, which is in breach with RFCs and therefor rejected by "well-behaved" smtps. sendmail and most other smtps swallows these lines afaik. hope this helps finding a bug Mit freundlichen Grüßen / regards Hartmut Steffin _______________________________________________ Nessus mailing list [email protected] http://mail.nessus.org/mailman/listinfo/nessus
