Ok, i had a problem like that before, so to my setup
Raspberry pi 2, newest updates and upgrades
Its running a Network bridge from lan to wlan
I have 3 interfaces, eth0, br0, wlan0
the bridge is still working fine
pihole is configured to use br0 for connections, working until reboot
Now no SSH access is possible anymore
Had someone the same problems? Internet must be working else the network bridge wouldnt work and i dont want to restore to my old backup all the time and then install everything again when i need to reboot the system....
Pihole is configured with static ip, checked that already
Was not configured to use an IPv6 thingy
Was configured to use the br0 interface since eth0 would kill the interface access for the pi (resolved that on github)
any help maybe why this is happening? and how to resolve that? found no answer anywhere till yet
I have the exact same issue. I cannot access my pi anymore since installing pihole and doing a reboot. SSH tells me that the devices fingerprint changed and this could be something nasty.
What is this? I don't like this.
I found the problem: Pihole will not solve local domains like myserver.fritz.box. I think it tried to login on some internet address. How can I tell pihole that fritz.box is the local network?
There are several posts about Fritz!boxes. I recall seeing some post about upgrading the firmware fixed a lot of issues. Nonetheless, take a look here.
In my case, the super server daemon "inetd" is listening on port 22 and boots up an sshd daemon when a client tries to connect and then forwards the client to the sshd daemon.
Another way of checking if sshd is active is to do:
$ ssh localhost
With later distributions, the sshd daemon wont start default at boot.
Need to do for example below to have the sshd daemon activated at boot:
so on netstat -nltp there are some things, also 2 times sshd
tcp 0 0.0.0.0:22 0.0.0:* Listen 812/sshd
and also this
tcp6 0 :::22 :::* Listen 812/sshd (i assume its ipv6 right?)
ssh localhost works but ping or overall internet access from withing the pi doesnt work,
ping to 8.8.8.8 doesnt work
ping to my computer doesnt work
ping to my fritzbox router doesnt work
@VexMex ,
yes those two entries mean sshd is listening on tcp4 and tcp6 port 22.
Could you run below, paste the output on pastebin.com, and post the pastebin link here please ?
ip link show; echo "---"; ip addr show; echo "---"; ip route show; echo "---"; brctl show;
Ps. run this one as user 'root' to make sure everything is included.
@VexMex ,
If you dont have ssh, you could redirect the output to a file on the '/boot' partition on the SD card as this is a FAT partition that can be read by most any PC.
So you just need to plug the SD card into another PC (remove power from pi first!!!) and look for the file 'network.txt':
(ip link show; echo "---"; ip addr show; echo "---"; ip route show; echo "---"; brctl show;) > /boot/network.txt
ok i have absolutely no clue what was wrong ebsides the static domain_name_servers and here and there few other things, but damn you are good, it now works like a charm, even after a reboot thanks very much for the help!!!
