Solution I installed network-manager and network-manager-gnome and removed my wlan1 card from /etc/network/interfaces. The card remained stably connected for over 20 hours and only disconnected when I shut down the raspberry pi. The WPA Gui says "cannot get status from wpa_supplicant" but the card works anyway. Looks like nm-applet has problems with ...
To properly secure ssh access, you must not allow authentication free login. Set up an RSA key for authentication, and then the client can use that instead of needing a password.
You need to tell PAM also that you want to allow empty passwords. There is some outdated tutorial describing that. But in short: sudo sed -i 's/nullok_secure/nullok/' /etc/pam.d/common-auth should do the job.
Create a new file /etc/modprobe.d/rt2800usb.conf with the following line : options rt2800usb nohwcrypt=1 Reboot Or blacklist the defaut drivers and use the nl80211driver to connect through wpa_supplicant: nano /etc/modprobe.d/blacklist.conf add the following lines: blacklist rt2800usb blacklist rt2x00lib blacklist rt2x00usb Connect through the ...
In my case, these messages appeared in /var/log/secure when I was experiencing Host key verification failed. errors on the ssh client side. This is one of the cases that would result in a connection without a login attempt.
This does the trick for me, at least in Ubuntu: sudo -u martin-test -s It forces you into the shell of the given user. For users who do not have the su requirement, maybe this is an acceptable alternative.
Check that you can resolve the name of this server with 'nslookup' If not, switch off 'UseDNS' at /etc/ssh/sshd_config, or add your host to /etc/hosts Should help.
Root cause of 98% similar problems is UseDNS parameter in /etc/ssh/sshd_config. Switch its value to no and try again
You can set number of password prompts to zero as below, -oNumberOfPasswordPrompts=0 P.S. Even though this is not relevant to your question, you might also find following useful (especially if you are trying to connect to random IPs). -oStrictHostKeychecking=no This will skip key validation with the knownkeys file in the target machine. I'm using ...
It's good practice to avoid putting passwords directly in /etc/fstab (which is normally world-readable). Instead, put them into a file, and reference the file like: //w.x.y.z/Home$ /mnt/dir cifs credentials=/home/username/cifs.creds,sec=ntlmssp,file_mode=0700,dir_mode=0700 /home/username/cifs.creds is owned by a suitable user (either root, or a user that ...
When you type the mount command, the part password='C' is first handled by the shell and becomes password=C before it gets to the mount command. This is not done with fstab entries, so you must remove the single quotes. If your password contains special characters you can replace them by their octal code, in particular \040 for space.
However if I try to connect from outside the docker conatainter / host I get prompted for a password. Should this happen? My assumption was that since I only configured the Port parameter everything else would be turned of including password authentication. Yes. The password authentication is on by default, because it is sometimes the only method you ...
May others not fall into the same trap. Everything is actually fine. From the testing section of the authd documentation: Execute "telnet localhost auth" and type the two ports separated by a comma. The two ports selected must have a foreign address of localhost, or 127.0.0.1 as well as a matching local address. If they do not, a NO-USER error will be ...
