ssh works well but when you try to copy a file via scp you get this error
1 | no hostkey alg |
Go on your server and check if you have /etc/ssh/ssh_host_rsa_key and /etc/ssh/ssh_host_dsa_key files, if not, generate them
1 2 | ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_keyssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key |
After installing a container with lxc I wasn’t able to connect via ssh to my container, I get the following message :
1 2 | root@ns313:~# ssh 10.50.10.10Read from socket failed: Connection reset by peer |
Network works normally, I can ping, hotst both direction and I can get pages from apache’s container from the dom0.
I tried to connect to ssh from container, in local and I get the same error.
1 2 | root@container:/etc/ssh#ssh 10.50.10.10 -l rootRead from socket failed: Connection reset by peer |
Strange, first time ssh doesn’t work on any machine.
Try restart sshd

SSH keys are missing, to fix it, run this command :
1 | root@container:/etc/ssh# ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N '' |
A classic hack for linux users, connect via ssh without password.
First, on your client, generate public key
1 | ssh-key-gen -t rsa |
keep ~/.ssh/id_rsa by default.
Copy public key (~/.ssh/id_rsa.pub) from your client to the file ~/.ssh/authorized_keys2 on the server with the ssh-copy-id binary.
Then edit your ~/.ssh/config file on client side to custom your params:
1 2 3 4 | Host dev HostName dev.domain.com Port 22 User root |
Finaly, you can add an alias in your ~/.bashrc
1 | alias dev='ssh dev' |
Now, to launche a ssh connection, just run
1 | dev |
After installing Symfony 2 instead of viewing your website, you see this error message :
1 | You need to enable either the SQLite3 or PDO_SQLite extension for the profiler to run properly. |
It probably means you need to install the sqlite extension for php
1 | apt-get install php5-sqlite |
restart apache and that should to the tricks.
