Today we were using nmap to scan our network and when we scanned our Tru64 machines, telnet and ftp froze and timed out. We could not make any connections to those ports and existing connections froze. New connections were denied for about a minute after the scan was finished. I've checked with Compaq and on Securityfocus and neither place has any knowledge of this. We are running Tru64 Unix 4.0D patch kit 3 on Alpha 4100's and 8400's. The nmap command line that was used is: nmap -T Polite -O -p 23,139 -oM /tmp/lst 'xxx.xxx.16-44.*' /Jason Johns
