System Advanced Options
To view or adjust Advanced System Options click the “SYSTEM” Tab then select “ADVANCED”. The System|Advanced Setup page will open as shown below. There are several Tabs on this page that allow you change many XigmaNAS settings. Some Tabs are briefly described below and each is discussed in more detail later in this section of the Setup & User Guide.
Console Menu
This option is useful to prevent unauthorized access to the console menu and the shell, note that if this option is enabled only the shell will be accessible after pressing Alt+F2/F3.
Console Screensaver
After enabling this option the user will be able to specify the time in seconds before the console screen goes to standby/blank mode during no input activity.
Firmware Version Check
Firmware Version Check does check when enabled, if there is a newer firmware version ready for download when you use firmware upgrade option on embedded system installs.
System Beep
If your XigmaNAS server has a speaker or audio capabilities, XigmaNAS provides tones to the user when shutting down and when boot up is complete. These are provided for XigmaNAS installations that are ‘headless’, that is, where no screen or keyboard is left connected to the server. Tones may be disabled via the System/Advanced page using System Beep option as shown in the image above.
Kernel Tuning
Tuning will permit advanced users to tune some FreeBSD kernel parameters. This option toggles some kernel parameter settings to alternate values. Some Tuning example values for the Tuning option being selected (checked or de-selected (unchecked) are shown in the table below.
| Tuning Unchecked | Tuning Checked |
|---|---|
| net.inet.tcp.delayed_ack: 1 | net.inet.tcp.delayed_ack=0 |
| net.inet.tcp.sendspace: 32768 | net.inet.tcp.sendspace=65536 |
| net.inet.tcp.recvspace: 65536 | net.inet.tcp.recvspace=65536 |
| net.inet.udp.recvspace: 42080 | net.inet.udp.recvspace=65536 |
| net.inet.udp.maxdgram: 9216 | net.inet.udp.maxdgram=57344 |
| net.local.stream.recvspace: 8192 | net.local.stream.recvspace=65535 |
| net.local.stream.sendspace : 8192 | net.local.stream.sendspace=65535 |
| kern.ipc.maxsockbuf: 262144 | kern.ipc.maxsockbuf=2097152 |
| kern.ipc.somaxconn: 128 | kern.ipc.somaxconn=8192 |
| kern.ipc.maxsockets: 3072 | kern.ipc.maxsockets=16424 |
| kern.ipc.nmbclusters: 3072 | kern.ipc.nmbclusters=60000 |
| kern.maxfiles: 1064 | kern.maxfiles=65536 |
| kern.maxfilesperproc: 957 | kern.maxfilesperproc=32768 |

Power Daemon
The Power Daemon and Power Mode options configure the FreeBSD powerd Daemon. According to the powerd wiki page:
Regarding the power modes:
maximum Choose the highest performance values. May be abbreviated as max.
minimum Choose the lowest performance values to get the most power savings. May be abbreviated as min.
adaptive Attempt to strike a balance by degrading performance when the system appears idle and increasing it when the system is busy. It offers a good balance between a small performance loss for greatly increased power savings. May be abbreviated as adp.
hiadaptive Like adaptive mode, but tuned for systems where performance and interactivity are more important than power consumption. It increases frequency faster, reduces frequency less aggres- sively, and will maintain full frequency for longer. May be abbreviated as hadp.
ZeroConf/Bonjour mDNS
About ZeroConf:
By default, XigmaNAS will announce this available service (multicast) with the Zeroconf protocol. This will permit other computers to detect that there is a computer that provide FTP, SSH, SAMBA, AFP, etc…. services. Zeroconf/Bonjour is used by Apple computer and newer Linux distributions.
