Hi all
it's a while that when i login i cannot connect to internet, at first i thought twas a router/modem issue, even because i can access modem and router ips while internet no
but to be short, i've tried to disable cabled connection from panel thingy and re enable it and i can go to the internet
i think there's some conflict or maybe some demon which has to be delayed a bit.. any hint?
Try to up the interface manually:
su
ifconfig
Find what is your device (e.g. eth0, eth1, or so), then:
ifdown eth0
ifup eth0
If no success, reboot your router and your machine after.
uh..... i don-t think i-ve had the feedback i should have had.,...
$ su

Unknown interface eth0
Your eth0 interface is up, it recived some packages, no errors.
The problem must be somwhere else...
Are you sure your router is fine?
i mean
first it told me:
root@linuxschifo:/home/carlo# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
then
root@linuxschifo:/home/carlo# ifdown eth0
Unknown interface eth0
now that i-ve rebooted i-ve tried again and this is the outcome:

useless to add that i couldn-t link to the internet and hat to turn cabled connection off and on from the cinnamon panel thingy
QuoteAre you sure your router is fine?
i-m not very sure cause besides linux things i have updated router firmare as well lately, but even reverting to an older fw didnt help
what i-ve noticed is that from this very computer linux behaves this way, even with different accounts, if i start windows internet worlks properly, if i link wireless to the router it works as well
Show me:
cat /etc/network/interfaces
cat /etc/resolv.conf
systemctl status network-manager
lspci -v
dmesg | grep net
this is what i get after i have done the trick with the utility, tell me if you need me to do it as soon as i reboot as well, here you gooo!

(what did i do to my computer?)
What kernel?
Have installed Sparky kernel or just default's Debian?
i-ve got not a clue,
this is my uname -a:
Linux linuxschifo 4.4.0-1-amd64 #1 SMP Debian 4.4.6-1 (2016-03-17) x86_64 GNU/Linux
half a good new:
i-ve activated sparky testing repos,
installed the kernel package, rebooted and goodbye X (i think it could be nvidia drivers fault)
i logged from textual and could upgrade whole system
the i've rebooted and X didn't start either
so
now i've used the "old" debian kernel and X works and Net as well!
no.. debian testing kernel, graphic session, but somehow locked internet connection yet
Hi Carlo,
If your problem isn't solved by now, I would throw in my own suggestions, even though I am no Linux/Network pro...
My question is pretty simple : have you entered a DNS server ?
I can't tell with this distro, but I know of some OS'es that will refuse to the internet until you have specified the correct DNS server (maybe your router or something more general, like 8.8.8.8 and "google.com" as a domain...).
Regards.
actually i didn't touch the dns settings at all
the onlu thing i did was installing privoxy, but so far it gave no problem
i suspect there's some conflict between desktop environments tools......
odd thing is that one time out of ten connection works without any intervention of mine (like now)
Hi Carlo,
OK. But it's an easy check, so maybe it's worth giving it a look even if you didn't touch anything.
I reckon you probably have other devices that are networked : a printer, a NAS, a router or an ISP box.
Are you able to reach those ?
It's just to check if it's a LAN or WAN problem...
Regards.
FRED
just turned this machine on:
i could access the nas, the modem, the router and the printer, but not the outer world
while my mobile, linked in wifi, nicely reaches the outer world
Hi Carlo,
OK... so definitely a WAN problem and not a LAN problem.
How do you access the internet ? With a router or with a deivce directly plugged into your computer ?
Regards.
there's the modem, which is linked with a cable to the router, and my pc is linked to the router with a cable
actually:
the modem is a very loosy one, provided by my isp, i cannot change it and it's working as a router as well, otherwise the nas is not reachable form the outer world
i had to add a router who works as an access point to that thingy because the modem isn't supporting many cabled connections at once and because the modem doesn't seem to appreciate the powerlines...
hope i've been celar enough
Hi Carlo,
Well, can't say that I understood what your config looks like really...
But that is not important.
The important part is that your machine does not seem to be connected to your modem directly.
I would try to connect the modem directly into the computer to see eliminate the possible causes of problems one after the other...
And of course, if your modem also has a router, make sure I can ping that and that the router is correctly configured...
Here's an example : my machine just froze (really, not Sparky though).
On reboot, my openssh-server did not start again ?
Why ? Because it seems the freeze screwed my network config a little... so had to reconfigure the router to redirect the ports as it should...
Regards.
FRED
actually it all went ok till i have updated the router and had to hard reset the modem
i actually do not know how i should modify routers' settings, maybe i should try to make some mess when i'm not linked to the outer world?
what really pisses me off is that on the very same machine if i start windows or puzzle linux it works, if i start sparky not
Hi Carlo,
If you can access the outer world with Windows or another Linux Distro, and if your problems arose after you had to hard reset the router, then we're moving forwards.
Go to your other Linux machine and check it's connection settings... and you shoud find out if it connects to the router over DHCP or if you entered the LAN IP address locally.
Write down those settings and apply them into Sparky.
If you're connected with DHCP, look down the router address and try to access it with your browser. And look at the router's settings. That may help also.
In case it's needed, simply clear your Ethernet connection, and replace it with a spanking new one :-)
Regards.
hi Nexus, thank you for your concernment
problem isn't with this machine, but with sparky on this machine only: all of the other machines, and puzzle linux and windows which are installed on this computer can access the internet without issues
i've never set an ip manually at home, though i tried to do it with the modem, but it's impossible as far as i can tell
now i've run from terminal sudo dhclient and connection started working
i have a little suspect:
on the modem there's my ip 192.168.1.64 which says it's dchp lease infinite
on the router i've clicked on lock this address to my mac so that i hope to keep that address even if the modem dhcp reboots or whatever
now i start thinking this might give some issues between modem and router
maybe pav was right and it's kernel fault:
i have started some kernel version which conflicted with nvidia, and from the terminal i had to give dhclinet, nevertheless i've upgraded the system and i've installed the new 4.5.0.2 kernel
i've booted it twice, and internet started working from the very beginning.. let's hope!
EDIT:
All vain.. i think quickest solution is to format, but i'm too lazy to do it right now.., so i'll bear this issue for some more
MAYBE the solution has come
yesterday i've updated cinnamon control center, and since then seems like lan is working fairly from the very boot now..
i've tried to reboot four or five times so far and it hasn't failed yet.. let's hope
EDIT 25th of MAY:
Things have improved but not solved: so far it failed "only" twice
and i'm too lazy to format
