When you install or upgrade SQL Server, you get the latest version of SQL Server from your configured Microsoft repository. The quickstarts use the SQL Server 2017 Cumulative Update CU repository. But you can instead configure the GDR repository or the Preview (vNext) repository. May 10, 2010 Installation and configuration of inadyn on VTI and VIX images for being able to use service no-ip: 1) Download enigma2-plugin-extensions-inadyn.vuplus_1.2-r0_mipsel.ipk. 2) Copy it with ftp on the receiver in the /tmp folder 3) connect to the receiver in telnet and type the following command: ipkg install /tmp/enigma2-plugin-extensions-inadyn.vuplus_1.2-r0_mipsel.ipk 4) Modify in the receiver.
OPNSense Firewall Like PfSense, OpnSense is a FreeBSD based open source firewall solution. The distribution is free to install on one’s own equipment or the company Decisio, sells pre-configured firewall appliances. OpnSense has a minimal set of requirements and a typical older home tower can easily be setup to run as an OpnSense firewall. The suggested minimum specifications are as follows: Hardware Minimums. 500 mhz CPU. 1 GB of RAM.
4GB of storage. 2 network interface cards Suggested Hardware.
1GHz CPU. 1 GB of RAM. 4GB of storage. 2 or more PCI-e network interface cards. If the reader wishes to utilize some of the more advanced features of OpnSense (, etc) the system should be given better hardware. The more modules the user wishes to enable, the more RAM/CPU/Drive space should be included.
It is suggest that the following minimums be met if there are plans to enable advance modules in OpnSense. Modern multi-core CPU running at least 2.0 GHz. 4GB+ of RAM. 10GB+ of HD space. 2 or more Intel PCI-e network interface cards Installation and Configuration of OpnSense Firewall Regardless of which hardware is chosen, installing OpnSense is a simple process but does require the user to pay close attention to which network interface ports will be used for which purpose (LAN, WAN, Wireless, etc). Part of the installation process will involve prompting the user to begin configuring LAN and WAN interfaces. The author suggests only plugging in the WAN interface until OpnSense has been configured and then proceed to finish the installation by plugging in the LAN interface.
Downloading OpnSense Firewall The first step is to and there are a couple of different options available depending on the device and installation method but this guide will utilize the ‘ OPNsense-18.7-OpenSSL-dvd-amd64.iso.bz2’. The ISO was obtained using the following command: $ wget -c Once the file has been downloaded, it needs to be decompressed utilizing the bunzip tool as follows: $ bunzip OPNsense-18.7-OpenSSL-dvd-amd64.iso.bz2 Once the installer has been downloaded and decompressed, it can either be burned to a CD or it can be copied to a USB drive with the ‘dd’ tool included in most Linux distributions.
The next process is to write the ISO to a USB drive to boot the installer. To accomplish this, use the ‘dd’ tool within Linux. First, the disk name needs to be located with ‘ lsblk‘ though. Find Disk Device Names With the name of the USB drive determined as ‘/dev/sdc’, the OpnSense ISO can be written to the drive with the ‘dd’ tool.
$ sudo dd if=/Downloads/OPNsense-18.7-OpenSSL-dvd-amd64.iso of=/dev/sdc Note: The above command requires root privileges so utilize ‘sudo’ or login as the root user to run the command. Also this command will REMOVE EVERYTHING on the USB drive. Be sure to backup needed data.
Installation of OpnSense Firewall Once dd has finished writing to the USB drive, place the media into the computer that will be setup as the OpnSense firewall. Boot that computer to that media and the following screen will be presented. OpnSense Network Configurations Confirm the changes to the interfaces by typing ‘Y’ in the prompt. This will cause OpnSense to reload many of it’s services to reflect the changes to the interface assignment. Once done, connect a computer with a web browser to the LAN side interface. The LAN interface has a DHCP server listening on the interface for clients so the computer will be able to obtain the necessary addressing information to connect to the OpnSense web configuration page. Once the computer is connected to the LAN interface, open a web browser and navigate to the following url: http://192.168.1.1.
OpnSense DHCP Settings Scroll down to the bottom of the WAN configuration screen to continue.Note. at the bottom of this screen are two default rules to block network ranges that generally shouldn’t be see coming in to the WAN interface. It is recommended to leave these checked unless there is a known reason to allow these networks through the WAN interface!
The next screen is the LAN configuration screen. Most users can simply leave the defaults. Realize there are special network ranges that should be used here, commonly referred to as RFC 1918. Make sure to leave the default or pick a network range from within the RFC1918 range to avoid conflicts/issues!
OpnSense Configure LAN Interface The final screen in the installation will ask if the user would like to update the root password. This is optional but if a strong password wasn’t created during installation, now would be a good time to correct the issue! Once past the password change option, OpnSense will ask for the user to reload the configuration settings. Simply click the ‘Reload’ button and give OpnSense a second to refresh the configuration and current page. When everything is done, OpnSense will welcome the user. To get back to the main dashboard, simply click ‘ Dashboard’ in the upper left corner of the web browser window.
NAME inadyn - a client for open DNS servers. SYNOPSIS inadyn -h -help -u -username username -p - password password -a -alias,hash alias,hash -a -alias,hash anotheralias,theotherhash. -inputfile path/name -ipservername server:port url -dyndnsservername:port server:port -dyndnssystem service -proxyserver:port proxy:port -updateperiod ms -updateperiodsec sec -forcedupdateperiod sec -logfile path/name -background -verbose level -iterations iterations -syslog -changepersona uid:gid DESCRIPTION inadyn is a client for `open' name servers. That is, it let the user have an Internet recognized name for his machine by transferring to him some control over a name server that he does not manage. Some of the services that are offered by those open name servers are free of charge, and work even when the client machine does not have a static IP. The name servers that are supported by inayn are:. Its basic operation is to periodically check whether the actual IP of the client machine is the same one that is recorded in the name server, and update the name server records when there is a mismatch.
OPTIONS -h, -help Print a summary of the options to inadyn and exit.u, -username The username, if applicable. This might be referred to as hash.p, -password The password, if applicable.a, -alias,hash A host name alias.
This option can appear multiple times, for each domain that has the same IP.inputfile The file name that contains inadyn command options exactly as specified in the command line syntax (adds to those already present in the cmd line). The default configuration file name is '/etc/inadyn.conf'. It is looked at automatically if inadyn is called without any command line options. The format is as expected for a.NIX config the hash character is used to comment entire lines. Spaces are ingored.
The long options may be specified without - if placed at the beginning of the line.ipservername:port url The client IP is detected by calling 'url' from this 'ipservername:port'. Defaults to checkip.dyndns.org:80 /.dyndnsservername:port The server that receives the update DNS requests.
When no proxy is specified it is sufficient to set the dyndnssystem so that the default servers will be taken. The option is useful for generic DynDNS services that support HTTP update.dyndnsserverurl name The update path inside the DynDNS server.dyndnssystem An optional DNS service. For the acceptable services are one of dyndns at dyndns.org, statdns at dyndns.org or custom at dyndns.org. There is only one acceptable service for, which is default at freedns.afraid.org.
Other services are: default at zoneedit.com, custom at httpsvrbasicauth. The default service is dyndns at dyndns.org, which is believed to be used by most users, at least initially.proxyserver:port An http proxy server name and port. The default is none.updateperiod How often the IP is checked.
This value denotes millisecond (There are 1000 milliseconds in one second). The default is about 1 minute.
The maximum is 10 days.updateperiodsec How often the IP is checked. Here the value denotes seconds.
The default is about 1 minute. The maximum value is 10 days.forcedupdateperiod How often the IP should be updated even if it is not changed. The time should be given in seconds.logfile The name, including the full path, of a log file.background run in background.
Output is sent to the UNIX syslog facilities or to a log file, if one was specified.verbose Set the debug level, which is an integer between 0 to 5.iterations Set the number of DNS updates. The default is 0, which means infinity.syslog Explicitly sending the output to a syslog like file, such as /var/log/messages.changepersona uid:gid After init changes user ID and group ID to the provided ones. This allows dropping unneeded root privileges after startup.
