Problem with ssh [email protected]

[mnp55]

Hi,
i cannot connect my raspberry with ssh [email protected] by my macbook pro
I have back this message:
"ssh: Could not resolve hostname gmvpi.local: nodename nor servname provided, or not known"
I found by google a lot of solution without success.
Can you gel me?

thanks

[DeeJay]

Can you connect if you try the connection with

Code: Select all

ssh [email protected]

(substituting the numeric IP address of your RPi of course)

Maybe your RPi is not configuring the DNS entry in your home router to allow the mac to look up its .local name

[mnp55]

Thanks Deejay,
with ip number all is ok!

But I would use if possible the host name.
Any suggestion?

[DeeJay]

Here are 2 websites that claim to have solutions. I have not tried them.

Thanks Deejay,

Any suggestion?

Try running the avahi daemon on your RPi? It's the mDNS/Bonjour server that lets your Mac see your pi as http://hostname.local and ssh [email protected].

sudo apt-get install avahi-daemon

[mnp55]

Retanks,
I tried both link suggestion doesn't work.
When I try to ssh or web browser by win machine everything is ok.
I cannot use hostname.local just by my mac ....

[mnp55]

..... I have installed and running avahi ...

[DougieLawson]

Log on to your pi (using it's IP addr)
Then use:

Code: Select all

avahi-browse --all

to see your active avahi configuration. Close that program with CTRL+C.
And use

Code: Select all

avahi-resolve --address w.x.y.z # your RPi IP addr

to be sure it can resolve it.

On your Mac try ping w.x.y.z and ping pihostname.local # using the results from avahi-resolve.

[mnp55]

Tankyou for answer when I try "avahi-browse --all"

I have the answer "-bash: avahi-browse: command not found"
....

Tankyou for answer when I try "avahi-browse --all"

I have the answer "-bash: avahi-browse: command not found"

Ah, sudo apt-get install avahi-utils should fix that.

[mnp55]

ok, thanks

avahi services installed and run :

ssh [email protected]

gmvmac$ ssh [email protected]
ssh: Could not resolve hostname gmvpi.local: nodename nor servname provided, or not known
and i cannot ping ...

any other suggestion will be appreciated ..

[mnp55]

... update ...

in my finder i can see raspberry as hostname and access it.

It just in ssh and in web browser that hostname cannot be solved

ssh [email protected]
and http://gmvpi.local (assuming you're running a web server)
should both work

can you ping gmvmac.local?

To see what services are running

Code: Select all

netstat -tan

Dougie thank for answer.
My system:

Raspberry pi --- Ip 192.168.1.20 hostname gmvpi

On Mac
I can ping Raspberry by Ip
I see Rasberry hostname in shared of finder, and I can access to files
I can Sftp://gmvpi
I can http://192.168.1.20
I cannot ping [email protected]
I cannot http://gmvpi.local

The problem is ssh [email protected] and http://gmvpi.local
any suggestion ...

[FinnAnder]

Try ssh [email protected]
I've a feeling it's because your Mac is .local
Also, try editing /etc/hostname and see if that's the correct host, if it isn't, then change it, write it out and then reboot.
Hope this helps!

[mnp55]

also this not work:

macbookvescovi3:~ gmvmac$ ssh [email protected]
ssh: Could not resolve hostname gmvpi.workgroup: nodename nor servname provided, or not known

[mnp55]

PROBLEM SOLVED!!
thanks to DeeJay, Dougie, Finn.
In my macbook pro
system preference --> Network --> Advanced --> DNS I changed in domain from "Workgroup" to "local"
now i can ping Raspberry as [email protected] and
http://gmvpi.workgroup it's ok also!!
also in ftp as gmvpi.workgroup it's ok

So the problem wasn't the RPi. The problem was in OSX. Am I surprised?

[mnp55]

yes is in osx.
I have erratic behavior ....
so:
some time i can ping gmvpi.workgroup
other time just gmvpi.
never gmvpi.local
the only constant is ping raspberry directly with its ip

[FinnAnder]

Glad you got it working!

[RocketRancher]

Actually there's no problem with OSx.
In the Pi, edit /etc/resolvconf.conf and de-comment "home"
