Hello Byung-kwan Kim, Here is a link to the Dell Unity Family Security Configuration Guide which states which ports can be disabled and which should be left open.  The guide also has our best practices for security settings as well. [URL]
Hello all,   I'd like to disable some TCP ports (ex. 139, 445) for security reasons (caught on internal port scan during security audit) I know I can disable it on NAS configuration via web management but, I want to make these ports can't be scanned.   I've checked all svc_* commands but nothing seemed to be make that happen. 1. svc_firewall only supports for UDP 2. tcp_wrapper(hosts.deny) doesn't support for smb/cifs 3. no parameters for svc_nas param cifs facility   Is there any methods I can try? Thanks in advance.   Kind Regards,
