PuTTY and WinSCP fail but xFx shows activity

Have I missed soemthing...... I've recently set up a HAHub(HAH9) as a clone of my fully working home system Hub(HAH1), and put it onto a remote LAN.... I've tried to remotely access HAH9 and can't get onto it, so I'm using LogMeIn to access a PC on the remote LAN and try and play with HAH9 'locally' - but PuTTy opens up, shows a cursor and halts with no login, whereas WinSCP will open up, Say 'Searching for Host' then 'Connecting to Host' then error out with 'Host not communicating' and I have to abort out... xFx viewer works fine and shows that HAH9 is active but the Pachube instance only refreshes every 2.5 mins not 60 seconds like all the others...CurrentCost ch1, 2 and 3 and total and temp are all picking up data correctly, but nothing is getting through to Pachube!

Any ideas, please!!!

Sounds like you have duplicate MAC address issue.  Did you adjust this for your 2nd unit?  A UDP broadcast will work regardless of this issue (even if its very bad condition) everthing else that uses TCP will just bomb.

Its on a separate LAN

Hi Brett

The other HAHub is on a physically different LAN, with only a router and a PC on it.....I'm linking to the rempte PC and trying to PuTTy onto the hub from that PC - no joy!

The part that throws me is the Pachube heartbeat is 2.5 mins between beats, but the xFx viewer shows interval=60 - and nothing is being posted onto Pachube even though the CurrentCost ch's are valid and active...!

I've changed the MAC addresses again - no better.....

Still no joy...

Hi Brett et al.....

I've physically re-booted everything and the problem persists...... I have just noticed that the HAHub displays Jan 1 even after re-boot.... does this indicate it's not getting through to t'Internet?

PuTTY and WinSCP fail to log into the hub, but I can get the web gui fine!

I've DMZ'd the hub if you want to have a look I can PM you the url!

Failing that, I've got another hub to try on Sunday......

Ta!

I could be a long shot, but have you check you've enabled SSH through the web GUI?

Without a valid timestamp on

Without a valid timestamp on your box SSL will fail.  Its a requirement that clocks be no more than 2-3min out otherwise SSL will fail.  Enable telnet that will get you in.

If the clock isnt' synching the you have a DNS lookup issue on the livebox.

UPDATE: Also make sure that the NTP host that is configured is a valid NTP time source and that you can resolve this hostname once you have TELNET access on your box enabled.

See the screenshot -> http://www.dbzoo.com/livebox/webserver#network_services

Thanks Brett - the NTP is the same as on my working hub (but I've re-entered it and saved and re-booted...no fix)

I've not used telnet so I'm going to read up and have a go.... otherwise, is there anything I can do to resolve the DNS lookup issue?

I'll PM my dnyalias if it'll help....

Regards....EJ

Putty has a TELNET option

Putty has a TELNET option just do you what you normally do but change the RADIO button selection and enable TELNET as a service on the web gui which you said is working.

Once on the livebox use

# nslookup <host>

See telnet using putty screenshot below.

Are both the gateway and DNS

Are both the gateway and DNS set correctly in the web interface.  You could also try changing the DNS to an external server and not your local router.  Reboot if you change these.

Thanks KarlThat sorted it...I

Thanks Karl

That sorted it...I pointed to an external server and re-booted and everything is working perfectly...

except - when I look at the remote hub's GUI tab it shows the readings from my local iserver!  Its getting late so I'll take another look tomorrow.....

Thanks all - night nite

Did you recently upgrade your

Did you recently upgrade your cable modem/router?   As this would mean that its no longer acting as a DNS proxy.  I think virgin's new super duper cable modem does this as I noticed that when Derek got his new one DNS things started breaking too.  As instead of proxying via the cable modem now it prefers to pass along the external DNS server IP's.

Karl was on the money thou, set the DNS IP to be the external IP addresses instead.  That should be enough.  Telnet is handy which is why I've not removed this service, and why I indeed have it  :)

No, I took a pre-configured

No, I took a pre-configured hub to a new location that had a Virgin super duper cable modem for his Internet access.....changing the DNS server's IP to the external values cured the problems....

Now - when I link to his hub over t'Internet I can see the hub (responds very quickly) but when I click the GUI tab, after a couple of seconds I get the correct GUI interface screen (I've put an ID button onto his screen, so I know its his GUI I'm looking at) - BUT all the values shown are from my LOCAL i-server not from his (remote) i-server....how can I get his GUI to show his values?  Or have I done something wrong again?

Thanks for all the help, I really appreciate it....

EJ

PS Just had a thought - the remote hub has no Instance and the UID's are the same as my local hub....could that be the conflict?  I'll change the UID's on the remote and see if that helps!! EJ

PPS Didn't have any effect!  Changed the UID's on the remote hub and it still shows my local data on the GUI!!!!
