This part shouldn't be a problem as Linux Network UPS Tools have been around since at least 2008 according to this article that explains how to use them. https://www.linux.com/news/adding-ups-desktop-linux-machine/ Out of curiosity I did a few quick searches on "environmentally friendly" battery backup systems. Current UPS models from APC and Tripp Lite have "eco-friendly" ports which power down when the device connected to them is turned off or in sleep mode but they all use SLA batteries. They also have USB charging ports, which if you don't have a battery bank for you cell phone, would be very useful in a many hours / days long power outage. I use a dirt cheap laptop running Debian that doesn't have any life critical data on it that is plugged into a $2 used surge protector that I daily just pull the power plug out of it while it's running and then just plug it in somewhere else. Obviously, if you've got file servers and databases that are being constantly written to then you want a clean shutdown if there's a power outage.
Re: [PLUG] question on how to fix a mysterious DNS address problem
"How do I fix this and how do I discover where this mysterious 10.18.0.1 address is coming from? Your pc is using DHCP to configure networking, including DNS. This ip address is the LAN side of your network gateway and is used for local DNS lookups on your LAN. Which you might only have the 1 pc connected to your ISP's network device and don't have a need for local DNS lookups There's nothing nefarious going on here. This is standard DHCP network configuration. If you don't want this, you'll have to figure out to disable DNS configuration via DHCP in the netconfig script.
Re: [PLUG] LiFePO4 UPS?
I bought an APC 1400 back in the summer of 2014. Worked fine but the last power outage before I replaced the UPS battery my cable modem and router lasted about 20 minutes. It was fine for short outages but not few hours one. I installed a new Lead Gel battery in October of 2022. Now it lasts over 3 hours. But whatever keep the coax up offsite the battery dies so the out cable modem goes down. What I do if my wife other people are online I make my smartphone a wifi hotspot and goes through the cellular network instead. I only tried it when only a few neighborhoods were affected. If we have huge power outage we may get cell calls and SMS only. > On Jan 5, 2023, at 13:22, Keith Lofstrom wrote: > > I have an ancient Tripplite 700VA UPS, which is briefly > triggered maybe twice a year, and needs a new sealed lead > acid (SLA) battery maybe every two years.

Re: [PLUG] question on how to fix a mysterious DNS address problem
As you already discovered 10.0.18.1 is not routable private IP. You ISP (Comcast) does not put cable customers behind GNAT, I believe - so, as already mentioned above it is likely openSuse not your ISP "feature". If you run out of ideas, and following the comments in resolv.conf didn't get you anywhere - you could try to fish for leads by: sudo grep -r 10.0.18.1 /etc This will likely lead you to a systemd service and/or network manager config files, depending which one is managing your DNS config. I am less and less familiar with openSuse these days, moving slowly away to different distro(s), after decades or use Suse is becoming pretty nasty shop in my personal experience. They are unable to provide even the most basic billing support for paying individual customers, blocking emails due to broken infrastructure and abandonment, not even answering their corporate phone numbers, ., leading to completely unnecessary annual legal credit card billing disputes. Hope that helps, Tomas
Re: [PLUG] question on how to fix a mysterious DNS address problem
I’m guessing that your questions might be answered by reading the comments in your resolv.conf file, especially the part about it being autogenerated and the part about a manual page. Usually, personal computers ( contrast with servers ) use DHCP to configure their network settings. I’m guessing that is the case here. See these sources for more details. https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol https://doc.opensuse.org/documentation/leap/reference/html/book-reference/cha-dhcp.html https://learning.oreilly.com/library/view/-/9781119689010/c11.xhtml Regards, - Robert On Thu, Jan 5, 2023 at 5:33 PM American Citizen wrote: > Hello all: > > The past few days I have been trying to fix some problems with internet > tranmissions not going correctly > > I just now discovered a mysterious name server connection in my > resolv.conf file which I have no understanding off.

Re: [PLUG] question on how to fix a mysterious DNS address problem
That's probably coming from your router or networkmanager. I very much doubt your ISP is setting that. resolv.conf is written by networking daemons running on your local system, so I'd start looking at whatever is configuring your network locally first, then work from there. -Ben --- Original Message --- On Thursday, January 5th, 2023 at 4:58 PM, American Citizen wrote: > Some more information here about DNS 10.0.18.1 > > from URL https://www.lookip.net/ip/10.0.18.1 > > 10.0.18.1 > > Here you can find all lookup results for private IP address 10.0.18.1. > If you are trying to find how to login to your internet router, modem, > extender or wireless access point, you can access the built-in HTML > webpage by clicking the following link for http or https. > > The most used default username and password to gain access to the > administrative interface is 'admin' or 'setup' and in case of a TP Link, > Netgear or D-Link wireless (or Wi-Fi) router you can also find the > default settings on the back of the device.

Re: [PLUG] question on how to fix a mysterious DNS address problem
Some more information here about DNS 10.0.18.1 from URL https://www.lookip.net/ip/10.0.18.1 10.0.18.1 Here you can find all lookup results for private IP address 10.0.18.1. If you are trying to find how to login to your internet router, modem, extender or wireless access point, you can access the built-in HTML webpage by clicking the following link for http or https. The most used default username and password to gain access to the administrative interface is 'admin' or 'setup' and in case of a TP Link, Netgear or D-Link wireless (or Wi-Fi) router you can also find the default settings on the back of the device. If this doesn't work or you, then you could choose to reset the router. To do this, you need to press and hold it's reset button for approximately 10 seconds. This will restore the factory settings and enables you to log in with the details specified on the sticker. IP address 10.0.18.1 is registered by the Internet Assigned Numbers Authority (IANA) as a part of private network 10.0.18.0/24. IP addresses in the private space are not assigned to any specific organization, including your ISP (Internet Service Provider), and everyone is allowed to use these IP addresses without the consent of a regional Internet registry as described in RFC 1918, unlike public IP addresses. However, IP packets addressed from a private range cannot be sent through the public Internet, and so if such a private network needs to connect to the Internet, it has to be done through a network address translator (also called NAT) gateway, or a proxy server (usually reachable on port 8080 or 8081 if it doesn't work directly). An example of a NAT gateway would be a wired or wireless router you receive from a broadband provider. A gateway web interface should be available through the HTTP (Hypertext Transfer Protocol) and/or HTTPS (Hypertext Transfer Protocol Secure) protocols. To try this, you should enter 'http://ip address' or 'https://ip address' in the address bar of your favorite web browser like Google Chrome or Mozilla Firefox and log in with the username and password provided by your provider. You can use these types of (private network) IP addresses in your local network and assign it to your devices such as a personal computer, laptop, tablet and/or smartphone. It is also possible to configure a range within a DHCP (Dynamic Host Configuration Protocol) server to do the IP assigning automatically. === does this mean my internet provider is sneaking in this DNS covertly?

My solution is to get and wire external marine deep discharge battery to my UPS when I need to replace its internal SLA battery. They play nicely with the UPS and should last about decade for the similar cost to SLA. Basically, I am kicking the can down the road! Maybe, I will be able to UPS the whole house with an EV if/when I get one some years down the road and forget about these crappy, expensive UPSs. - T >

[PLUG] LiFePO4 UPS?
I have an ancient Tripplite 700VA UPS, which is briefly triggered maybe twice a year, and needs a new sealed lead acid (SLA) battery maybe every two years. Oh boy, more toxic waste, and shopping trips, and disposal trips. Theoretically, it can provide a signal that tells my computers to prepare for shutdown, but it doesn't seem to play nice with Linux. Most of the outages have been less than 30 seconds, so triggered shutdown is not a "must have". However, extra bonus points if the UPS /does/ behave well with more than one Linux machine. The load is two computers (250W) and perhaps one of two screens (another 60W?). Note that 700VA actually means something like 400W continuously delivered - perhaps the VA number covers the peak impulse power at computer startup, or during a power line excursion. New technology LiFePO4 batteries last much longer and are environmentally cleaner than an SLA, and are shape and terminal compatible, but they charge differently. I tried one and failed. Perhaps there is a warranty-voiding retrofit hack for the Tripplite, but for safety's sake I prefer to purchase an Uninterruptable Power Supply designed for LiFePO4.
