Extend ServerInfo to Support FreeBSD

[ghost]

FreeBSD doesn't use /proc/ to store system information, so multiple functions needed to be modified to support FreeBSD,

Modified Os.php to include new Class FreeBSD added check for when FreeBSD is the OS.

Created FreeBSD.php based on DefaultOS.php

Functions modified from DefaultOS.php

• Added constructor to use phpIni
• getMemory - use sysctl - mirror logic from SystemStatistics.php
• getCPUName - use sysctl -n hw.model
• getUptime - return kern.bootime subtracted from current time
• getTimeServers - remove /etc/systemd/timesyncd.conf as does not exist in FreeBSD
• getNetworkInfo - add gateway using netstat
• getNetworkInterfaces - modified to use ifconfig instead of /sys/class/net/*
• readContent - removed as now unused

Thank you 👍

Small change to get all ipv6 addresses in the loopback address

[kesselb]

Looks good. Did not test it.

[kesselb]

Mind to share some of the command outputs here (like https://github.com/nextcloud/serverinfo/tree/master/tests/data)? I can add some tests later with it. Just post it as comments here. No need to add it as files yet ;) Thanks 👍

#
# Default NTP servers for the FreeBSD operating system.
#
# Don't forget to enable ntpd in /etc/rc.conf with:
# ntpd_enable="YES"
#
# The driftfile is by default /var/db/ntpd.drift, check
# /etc/defaults/rc.conf on how to change the location.
#

#
# Set the target and limit for adding servers configured via pool statements
# or discovered dynamically via mechanisms such as broadcast and manycast.
# Ntpd automatically adds maxclock-1 servers from configured pools, and may
# add as many as maxclock*2 if necessary to ensure that at least minclock
# servers are providing good consistant time.
#
tos minclock 3 maxclock 6

#
# The following pool statement will give you a random set of NTP servers
# geographically close to you.  A single pool statement adds multiple
# servers from the pool, according to the tos minclock/maxclock targets.
# See http://www.pool.ntp.org/ for details.  Note, pool.ntp.org encourages
# users with a static IP and good upstream NTP servers to add a server
# to the pool. See http://www.pool.ntp.org/join.html if you are interested.
#
# The option `iburst' is used for faster initial synchronization.
#
pool 0.freebsd.pool.ntp.org iburst

#
# If you want to pick yourself which country's public NTP server
# you want to sync against, comment out the above pool, uncomment
# the next one, and replace CC with the country's abbreviation.
# Make sure that the hostname resolves to a proper IP address!
#
# pool 0.CC.pool.ntp.org iburst

#
# To configure a specific server, such as an organization-wide local
# server, add lines similar to the following.  One or more specific
# servers can be configured in addition to, or instead of, any server
# pools specified above.  When both are configured, ntpd first adds all
# the specific servers, then adds servers from the pool until the tos
# minclock/maxclock targets are met.

# Security:
#
# By default, only allow time queries and block all other requests
# from unauthenticated clients.
#
# The "restrict source" line allows peers to be mobilized when added by
# ntpd from a pool, but does not enable mobilizing a new peer association
# by other dynamic means (broadcast, manycast, ntpq commands, etc).
#
# See http://support.ntp.org/bin/view/Support/AccessRestrictions
# for more information.

#
# Alternatively, the following rules would block all unauthorized access.
#
#restrict default ignore
#
# In this case, all remote NTP time servers also need to be explicitly
# allowed or they would not be able to exchange time information with
# this server.
#
# Please note that this example doesn't work for the servers in
# the pool.ntp.org domain since they return multiple A records.

#
# If a server loses sync with all upstream servers, NTP clients
# no longer follow that server. The local clock can be configured
# to provide a time source when this happens, but it should usually
# be configured on just one server on a network. For more details see
# http://support.ntp.org/bin/view/Support/UndisciplinedLocalClock
# The use of Orphan Mode may be preferable.

Oops closed by accident. I cannot merge it myself.

[ghost]

#172 #203 Should resolve both

[kesselb]

Thanks 👍

[VVD]

1. "df -TP" use 512 bytes blocks size - correct command is "df -TPk".
2. No MTU - check 1st line:

ixl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9198
        options=e507bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>

        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

3. No CPU cores count: "sysctl -n kern.smp.cpus".
4. Total RAM is hw.realmem, but not hw.physmem.

[ghost]

Issues 1, 3 and 4 are resolved in #215
Adding mtu is an enhancement and needs to be added to the default OS and the template first. I have no interest in adding mtu so I suggest you create a pull yourself @VVD

[ghost]

For the record the change is simple for FreeBSD.php

preg_match("/(?<=mtu ).*/m", $intface, $mtu);
$iface['mtu'] = $mtu[0];

[VVD]

5. swapinfo need -k same as df: "/usr/sbin/swapinfo -k".

@constrict, I wrote patch 2 months ago: #203.

[ghost]

Does not seem to be an issue on my box but I have added -k to swapinfo, so that it is always shown in 1k-blocks.

Issue is actually in SystemStatistics.php. The swap return is unused in FreeBSD.php.

Hi all,

I have FreeNAS (FreeBSD) system running Nextcloud 18.0.6
Is there anything I can help with?

Thanks,

I'm still getting an 'Internal Server Error' when I try to access settings/admin/serverinfo on FreeBSD 12.1 with NC20.
Shouldn't this already work?

Same problem for me, with FreeBSD 12 and NC20...
