Thanks. I'll add that to my documents on this subject.
The hotspot has been stable for several days, now.
Thanks, again, to all who contributed.

Beating a very old horse here, but I've been intending to respond to
this. The reason these commands are failing is that redirection ('>')
is performed by your original shell, not sudo. Your rsteff account
doesn't have permission to write to files in the /proc directory, hence
the error. Others have shown that you can just get a root shell and
then issue the echo command, but I wanted to point out that you can do
this from a single command.
This command invokes a root shell and then passes the desired command,
including redirection, to that shell.
sudo /bin/sh -c 'echo 1 > /proc/sys/net/ipv4/conf/all/forwarding'

There are some things that require a root login shell rather than root access from a user shell. I don't know the details, but I learned a long time ago that when I build a Slackware package from the source tarball to do so from a login shell. Apparently, writing to the /proc filesystem requires the same attributes. Does PLUG have a wiki where solutions like this can be posted for posterity?

Okay. I'm starting to try this. I have a Thinkpad X200 laptop talking to my Verizon Ellipsis 8 hotspot. I'm looking at how to set the X200 eth0 to static, so I can connect it to my Buffalo WZR 600 DHP router. From: http://askubuntu.com/questions/470237/assigning-a-static-ip-to-ubuntu-server-14-04-lts it recommends putting the following into /etc/network/interfaces, with addresses suited to my situation: __ auto eth0 iface eth0 inet static address 10.253.0.50 netmask 255.255.255.0 network 10.253.0.0 gateway 10.253.0.1 dns-nameservers 8.8.8.8 __ The Buffalo router will be serving addresses in the 192.168.0.xxx range, so I assume I should use an address in a different range for the X200's eth0. ifconfig on the X200 shows the address of wlan0 as 192.168.43.206. I assume that's the address provided by the Ellipsis 8 hotspot. Does that mean that the X200's eth0 should be in that range? Or should I use something like 192.168.1.100? The netmask entry looks like every other netmask entry I've ever seen, so that's probably okay. What should the network entry be? Should it be 192.168.43.0, or 192.168.1.0, or something else? Am I correct in assuming the gateway is the address assigned by the hotspot? I know dns-nameservers 8.8.8.8 is Google's, and I assume that's okay. So, should /etc/network/interfaces look something like this? __ auto eth0 iface eth0 inet static address 192.168.1.100 netmask 255.255.255.0 network ??? gateway 192.168.43.206 dns-nameservers 8.8.8.8 __ I know I have to install isc-dhcp-server on the X200 before I can connect the router to it.

From there you might be able to set up wireless bridging. Russell's laptop idea or Rich's wireless adapters would be much easier to configure.

How long do you need it for? Probably a few days to a couple of weeks. When I get to it, I'll give the laptop option a try.

Oh, and yes (actually reading what you wrote), running it through a laptop can work. Laptop wifi connects to your mobile hotspot, ethernet connects your laptop to the WAN port on a router (or directly to a switch or desktop machine), give the ethernet interface a static IP on a different network from the mobile hotspot, e.g. 192.168.11.1/24, then run the command: iptables -t nat -I POSTROUTING -o wlan0 -j MASQUERADE (where wlan0 is your laptop's wireless interface connecting to the mobile hotspot). Then you'll need to run a DHCP server providing leases on the ethernet interface only, and you are done. You could do something similar with a router running OpenWrt in place of the laptop, with the radio in client mode, acting as the WAN interface. There, you have the nice advantage that the router already has a DHCP server built in. The key is to avoid trying to put a client-mode interface into a network bridge with anything. That is disaster, don't go there. Routing works fine, so use it and MASQUERADE'ing (i.e. NAT). -- Russell Senior, President russ...@personaltelco.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

It's not totally simple, though there may be off-the-shelf solutions too, but if you have an access point that is supported by OpenWrt/LEDE that also has a USB host port (many modern ones do), you can install kmod-usbnet and plug your USB dongle or USB tethered phone into the access point's USB port, and away you go, wifi and/or wired but with WAN provided over the USB connected device. PTP has built such things before. We had one at OSCON a few years ago, as a party-trick. Wifi is/was horrible in the exhibit hall, but it worked. -- Russell Senior, President russ...@personaltelco.net ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

[PLUG] How do I use a tablet WiFi hotspot for my desktop machine?
I may need to be without Comcast for a time. Is there a way to use a tablet WiFi hotspot and a laptop to feed my router so I can support two desktops? We got a small tablet from Verizon before going on a trip in June. It works well as a WiFi hotspot to connect our laptops. But since our desktops don't have radios, I'm hoping there's a way to make one of my laptops serve my router so I can continue to serve our desktops. I assume I'll need to install and configure something to be a DCHP server so the router can get an address from the laptop. To save on Verizon data usage, I probably won't leave the tablet connected to Verizon all the time. Is there something I'll need to do on the laptop so that it doesn't try to connect to the router when the tablet is off? Or maybe I don't actually turn the tablet off, but just disconnect it from Verizon. Advice appreciated. -- Regards, Dick Steffens ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
