raspberry pi networking

In trying to network my raspberry pi I’ve hit a ‘brick’ wall – removed one brick anyway.

FIRST BRICK REMOVED: Using an ethernet adapter (VOnets – from ebay – listed as
Wifi Bridge Dongle Wireless For Dreambox Xbox PS3) powered from a powered hub the startup commences and before the desktop the ‘barbers pole’ pauses with the following message in the task window:
Contacting DHCP server for ethernet over USB interface

After ten or fifteen seconds it goes on and the desktop appears with the following:
Machine startup has not completed successfully:’Route: add net default: gateway 192.168.61.1: Network is unreachable

I’ve done a check via status and LMTransport is set as IP

I’ve also checked the network files and entered the details for the hosts file. When I tell it to Save the network configuration it responds with Message from Internet Setup:
“RISCOSpi” is not in your Hosts file

NOTE: rechecked and made sure return was pressed at the end of the Hosts file and it then saved, shut down and then booted up correctly.

From Task window sent ping 192.168.61.1 and successfully transmitted and received. Network is at least operational.

SECOND BRICK

Next problem: Netsurf won’t connect with the Netsurf Configuration-Connection set to No Proxy I get: warning from Netsurf:
Could not resolve host: www.denmarkwa.biz/flora
(Could not contact DNS servers)

If I set Connection to Simple Proxy
Host 192.168.61.1 (my router connected to the internet and which has pinged successfully)

Warning from Netsurf:
Failed to connect to 192.168.61.1: Permission denied

Has anyone struck this problem and if so how did you solve it please?

edited to add details of ethernet adapter seeing as this one seems to work on raspberry pi

From Task window sent ping 192.168.61.1 and successfully transmitted and received. Network is at least operational.

I assume 192.168.61.1 is the gateway address on the wifi device or the address of your main gateway.

If that succeeds then try to ping 8.8.8.8 (or 8.8.4.4) if those don’t respond you aren’t connecting to the internet and Netsurf is of no use. 8.8.8.8 and 8.8.4.4 are googles DNS servers so they aren’t likely to disappear…

We have a satellite connection for our internet and this is connected to a wired/wireless router acting as the main gateway (192.168.61.1)

Thanks for the suggestion to ping 8.8.8.8 or 8.8.4.4

Neither works so it must be something to do with my gateway setup.

I am no expert but this article about putting Elite on the Raspberry pi under RISC OS has some useful pictorial information about how to get Internet running:

Give me a shout if you need help to swap files with a Windows p.c.

Thanks for that link Peter. It is the type of clear and concise instructions I like. I’ve still got no joy but wonder if it is a wifi problem. Tomorrow I’ll get out the ladder and run a Cat5 cable from the router to the RPi and check out my settings to ensure that I eliminate that element.

Will update this tomorrow.

If you have a PeeCee available then download and run this with a hub in the link between the test point and the gateway:
http://www.wireshark.org/download.html
It looks a bit opaque when you first start (years on I still recall the first steps in packet capture)
If you put in a filter for the source IP you are interested in and check the content of the packets you will probably spot the problem.

WireSalmon for RISC OS http://www.cp15.org/networking/ is something I haven’t tried, but should give similar results but probably not as refined.
Edit: Capture only on RO …

Are you sure that RISC OS actually supports a wireless dongle? I was under the impression that new drivers would be required to implement wireless networking.

Looks like a cheap ethernet to wireless bridge to me. From the info it looks to be doing at least part of the job already.

That would be for a USB connected wireless device where the specific control of the device came from the computer end

Thanks, Steve, for the clarification.

Thanks for the advice Steve. I’ve re-run my cat5 cable to reach the pi but still have problems. I suspect the mice may have chewed through the cable where it passes through the wall cavity. I’ll have to move things to get to the router and use a short, working cable.

If I can verify that the cable results in a stable connection I’ll be able to eliminate the on-board connector as a fault and label the wireless ethernet adapter as ‘iffy’ – it may not be able to handle the distance.

It is a cheap wireless ethernet adapter/bridge and it looks like I’ve got what I paid for. I may have to bite the bullet and buy a better quality one – I didn’t initially as it seemed a bit over the top paying nearly twice the price of the RPi for an attachment. All is not lost! My grandson can have the cheap bridge :-)

This would be a better product to use http://www.netgear.com.au/home/products/powerline give it a try

Thanks for all the advice. My basic trouble shooting instinct was correct. The mice had chewed through the cover of the cable and severed two cables and left others exposed. I cut out the damaged section, stripped and rejoined and “voila” it now pings consistently and Netsurf operates.

After I dragged all the bits and pieces to my monitor I discovered it didn’t have an HDMI input! Doh!

I’ve taken the plunge and purchased a $AU59 ethernet-wireless adapter and now have to wait for it to arrive. Not living in the city I’m an on-line shopper. I fancied the netgear option but when they asked for $20 shipping (within Aust) I went for a Belkin that wasn’t going to cost anything for delivery.

Will keep this updated when the new adapter arrives. I will have it before Christmas ;-)

If there are rodents around I’d say using a data delivery over power lines is a good idea to defend your connection. zzzztt! :-)

No chance of rodents in this house – toys like that don’t live long with three furry people to play with them. The rabbits in the local wood have to be fast too.

I’m glad your furries are productive. Recently a mouse fell into the back kitchen where the furballs live and I think it saw them and died of a heart attack. Meanwhile the furries just sat there, probably thinking “Isn’t my human supposed to be shaking this toy? Come stroke me, human!”.

My tip – snap-trap baited with peanut butter for the mice, and furries as wannabe hot water bottles. (^_^)

UPDATE:

Received a Belkin Universal Wireless HDTV Adapter SCREENLINK this afternoon. Connected it up and lost the mouse, then the keyboard. After mucking around switching the USB attachments back and fro decided to get the $AU50 powered hub. Then read the instructions. Went back to Networking and told it to DHCP and I now have an operational network.

Through the wall I have gone with a number of lessons learnt (who said you can’t teach an old dog new tricks!)

Not only is the raspberry pi finicky about its power supply it needs good quality peripherals. Cheap powered USB hub now replaced with $50 unit. Cheap Wi-fi bridge/adapter now replaced with $59 unit. The $48 Logitech 520 cordless mouse and keyboard combo is now functioning without the freezes common on the cheap USB hub.

It would seem that any problem with the RPi can initially be checked by making sure you have quality attached. :-)

I’ve also got fedora remix for RPi operating successfully with this set up.

Re creatures great and small

Our mouse problem is not one I want to solve with a furry creature as we have a few other residents who would object. Four nights in the past ten I’ve had a phascogale wandering the verandah illuminated by Christmas lights seeking any hapless insect that might come his way.

We also have quendas and abundant reptiles and bird life now our beloved Burmese has left – checked out after 17 years. The locals now have priority.

Not only is the raspberry pi finicky about its power supply it needs good quality peripherals.

My Pi… plugged into the eeePC’s USB port, works fine. The mouse is an old generic thing rescued from a bin at work. The keyboard “has quirks” but this problem happens with Linux too. USB flash, generic 1GiB thing. SD card, Verbatim or SanDisk. Not tried anything else, but I don’t necessarily agree that you need quality – just an awareness that there’s cheap and there’s cheap. For instance, a hub bought at “PoundLand”…sorry, I wouldn’t lower myself to even attempt to connect it.

Point taken Rick. Perhaps I should have clarified that point – but generally one gets what one pays for. The difficulty is knowing which of the lower priced items is better quality realising that the most expensive is not necessarily the best. You’ll see from my prices I’ve gone for middle of the road and names that have a better or known reputation. The range available to me living in the country some 440km from the city is also limited (for hands on shopping that is).

Once again I’d like to thank everyone for their advice. :-)

I have two Pi’s. Pi1 is already in a network (wired, switch) and sees my Iyonix and VRPC (Mac). I configured Pi2 yesterday and attached it (wired, same switch). Pi2 doesn’t see Pi1, Pi1 doesn’t see Pi2. I renamed the harddrive of Pi1 and reconfigured the network settings. No succes. The name of the drive on the ibar is still :0, although the name in the title bar of a window is SDFS::Pi1.$. Both have a working connection to internet.

What can I do to make a meet Pi?

Have you try a *ping [ip] and have you try ShareFS at first?

Maybe your router is configured to disallow communication between connected devices? My router does this by default if you work via the “guest” connection.

I configured Pi2 yesterday and attached it (wired, same switch). Pi2 doesn’t see Pi1, Pi1 doesn’t see Pi2.

What devices on the local network can the Pi2 see?

What devices on the local network can the Pi2 see?

None.

I have Pi1, Pi2 and the Iyonix active.
Pi1 and Pi2 see the Iyonix,
Pi1 doesn’t see Pi2,
Pi2 doesn’t see Pi1
Iyonix doesn’t see Pi1 or Pi2.
In all machines in Network configuration Access is enabled.

The traffic is done by a switch, the router is not involved.
