Why ‘Play Sound’ alert doesn’t work in my browser?
Q: I can hear sound alert file playback, and can hear sound alert when monitoring service executes it. However, i can’t hear sound alert when using Web interface. Why?
A: The most probable cause is Flash Player (which web interface use for playing mp3 sounds for ‘Play Sound’ alert) that blocks any activity on some ports because of the security issues (these ports are reserved for some protocol). The following lists show which ports are blocked in Flash Player:
HTTP: 20 (ftp data), 21 (ftp control)
HTTP and FTP: 1 (tcpmux), 7 (echo), 9 (discard), 11 (systat), 13 (daytime), 15 (netstat), 17 (qotd), 19 (chargen), 22 (ssh), 23 (telnet), 25 (smtp), 37 (time), 42 (name), 43 (nicname), 53 (domain), 77 (priv-rjs), 79 (finger), 87 (ttylink), 95 (supdup), 101 (hostriame), 102 (iso-tsap), 103 (gppitnp), 104 (acr-nema), 109 (pop2), 110 (pop3), 111 (sunrpc), 113 (auth), 115 (sftp), 117 (uucp-path), 119 (nntp), 123 (ntp), 135 (loc-srv / epmap), 139 (netbios), 143 (imap2), 179 (bgp), 389 (ldap), 465 (smtp+ssl), 512 (print / exec), 513 (login), 514 (shell), 515 (printer), 526 (tempo), 530 (courier), 531 (chat), 532 (netnews), 540 (uucp), 556 (remotefs), 563 (nntp+ssl), 587 (smtp), 601 (syslog), 636 (ldap+ssl), 993 (ldap+ssl), 995 (pop3+ssl), 2049 (nfs), 4045 (lockd), 6000 (x11)
