I have a directory named:
-2
I want to cd into it but the cd complains:
bash: cd: -2: invalid option
With no success, I've tried:
cd "-2"
cd '-2'
cd \-2
Any solution?
Edit: no file browsers like mc, etc. available on the server.
I have recently started using LVM on some servers for hard drives larger than 1 TB. They're useful, expandable and quite easy to install. However, I could not find any data about the dangers and caveats of LVM.
What are the downsides of using LVM?
I just checked my server's /var/log/auth.log and found that I'm getting over 500 failed password/break-in attempt notifications per day! My site is small, and its URL is obscure. Is this normal? Should I be taking any measures?
This is a question regarding the OpenSSH client on Linux, MacOSX and FreeBSD.
Normally, I log into systems using my SSH key.
Occasionally, I want my SSH client to ignore my SSH key and use a password instead. If I 'ssh hostname', my client prompts me for the Passphrase to my SSH key which is an annoyance. Instead, I want the client to simply ignore my SSH key, so that the server will ask me for my password instead.
I tried the following, but I am still prompted for the passphrase to my SSH key. After this, I am prompted for my password.
ssh -o PreferredAuthentications=password host.example.org
I want to do this on the client side, without any modification of the remote host.
Is there a way to connect to an ssh session that was disconnected? We are having problems with our network connection to a remote site that we are working on separately; however, in the mean time we experience a large number of disconnects due to lost packets while connected to servers at the remote location. Many times the session stays active for a while, and sometimes it happens to be in the middle of some action (file editing, running some process, etc...) that I need to get back to rather than restart if possible.
