I am trying to ssh to my home router from local network, to explore it's internals.
shh myaccount#192.168.1.1
returns an error:
Unable to negotiate with 192.168.1.1 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1
To fix it, I ssh with -o option:
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 myaccount#192.168.1.1 -v
At first, ssh hangs for around 5 minutes and than quits.
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 myaccount#192.168.1.1 -v

What is going on? I don't see any error message. This is my first time trying to ssh to home router, so it might not be possible at all. Whats your experience with ssh-ing to home routers?

https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/SingleCluster.html
I have set up a Kerberos cluster with docker containers as such:
One container runs the KDC.
One container has SSH server.
One container has SSH client.
Server setup
I create a service principal host/krb5-service.myexample.com for the server, create a keytab with that principal and places it in the krb5-server container.
I also created a user in the krb-server container named "yoav" - Don't know if that's necessary..
Client setup
I also create a client principal john. Then I run kinit yoav inside the krb5-client container.
Now I try to connect with SSH from the client to the server
$ ssh yoav#krb5-server.myexample.com
That's what I get as output:
# KRB5_TRACE=/dev/stdout ssh -vvv -o PreferredAuthentications=gssapi-with-mic yoav#krb5-server.myexample.com

I'm trying to use Gitlab for the first time, and have been trying to set up my account to automatically ssh in. I've followed instructions and tried many different times, but no matter what, I can't ssh to gitlab properly.
I've tried deleting my id_rsa and id_rsa.pub files and regenerating keys, using the command line to copy the contents of id_rsa.pub to my Gitlab user settings (both with a newline and no newline at the end of the paste). I added my key using ssh-add. I'm running ssh -vvvv git#gitlab.com for verbosity and I just cannot connect succesfully for the life of me.

Permission denied (publickey).
It has to be some small dumb mistake somewhere, but I just can't figure it out. If it helps, when I do ssh-add -l, my fingerprints look like a hash for some reason.
Do check that:
when you copy the public key in your GitLab settings profile, it is copied as one line
when you generate your RSA SSH key, you use the old legacy profile (in case the new OPENSSH one with 70 chars per line is not well interpreted)
That is
ssh-keygen -m PEM -t rsa -P "
I carefully follow official documentation how to connect to self-hosted GitLab from Windows (tried with VisualStudio and Tower).
But connection is not established.
From Troubleshooting section I run ssh -Tv git#gitlab.mydomain.com and get this:

git#gitlab.mydomain.com's password:
It outputs
No such file or directory
, but my id_rsa.pub exists:
I added my public key to my profile in GitLab: cat ~/.ssh/id_rsa.pub | clip.
My repository https url is: https://gitlab.mydoamin.com:3000/web/oppis.git and it works (not sure if port matters), but not with SSH.
Edited:
I know path is strange for Windows environment, but I don't know how to fix this. Also when executing ssh-keygen -t rsa -C "your.email#example.com" -b 4096 suggested path for saving keys are "strange": /c/Users/matjaz.cof/.ssh, but files are saved. So I though this should work.

I found something strange:

Strange is I have id_rsa.pub and id_rsa files. (They were create with GitBash ssh-keygen -t rsa -C "your.email#example.com" -b 4096)
So I change id_rsa.pub to id_rsa and id_rsa to id_dsa.

Problem was in firewall. I forget to set Harpin NAT.
My firewall allowed me to connect to port 22. I also route port 22 to GitLab machine IP. But forget to set Harpin NAT.
That means If my public IP is 1.2.3.4(gitlab.mydomain.com) I could connect to gitlab.mydomain.com from any public IP except (1.2.3.4).
Router didn't know what to do with packets, because LAN machine tries to connect to another LAN machine via the external IP address. (WIKI)
As discussed on chat, this turns out to be a firewall problem at your office. Your firewall probably blocks outgoing connections on port 22 to other server.
This is the main reason for not being able to reach to the SSH server and that is why it works from your home network and not from office
I am able to login to my virtual server as root as well as username naveed through password-less SSH. I have to run Hadoop on it, for that purpose I have created private and public keys in my remote ssh directory and also added public key to authorized_keys file.
But when I do ssh comquest it asks for password. Comquest is hostname of my remote server.
Below are my permissions info:
naveed#comquest:~$ stat -c "%a %n" ~/.ssh
755 /home/naveed/.ssh
naveed#comquest:~$ stat -c "%a %n" ~/.ssh/authorized_keys
644 /home/naveed/.ssh/authorized_keys
Below is the error I got with naveed#comquest:$ ssh -vvv comquest
naveed#comquest:/usr/local/hadoop$ ssh -vvv comquest

authorized_keys known_hosts local local.pub
local and local.pub are keys generated by naveed#comquest to access comquest. local.pub is added to authorized_keys.
Your private key is in a file named local, but that's not a name that ssh looks for (by default). Your ssh -vvv output shows that it's only looking for the default key filenames, such as id_rsa and id_dsa.
Either rename your local and local.pub files to match the expected naming convention (e.g. id_rsa or whatever, depending on what type of key it is), or add -o IdentityFile=~/.ssh/local to your ssh command line.
