I realise purists would say "use the command-line" but this is the age of Ubuntu and since I spend most of my time behind a proxy server I find it easier to configure and use PuTTY on Windows than configure ssh with connect.c I also realise PuTTY is available on Linux but it seems to use some weird GUI widget set that is rather nasty t...
How do I setup Public-Key Authentication for SSH? ...
I'd like to allow a user to set up an SSH tunnel to a particular machine on a particular port (say, 5000), but I don't want to restrict this user as much as possible. (Authentication will be with public/private keypair). I know I need to edit the relevant ~/.ssh/authorized_keys file, but I'm not sure exactly what content to put in there...
I absolutely love the Keep Remote Directory Up-to-date feature in Winscp. Unfortunately, I can't find anything as simple to use in OS X or Linux. I know the same thing can theoretically be accomplished using changedfiles or rsync, but I've always found the tutorials for both tools to be lacking and/or contradictory. I basically just ne...
Trying to setup an SSH server on windows server 03. What are some good ones? Preferably open source. I plan on using WinSPC as a client so a server which supports the advanced features implemented by that client would be great. ...
I have recently started having problems with TortoiseCVS, or more specifically with plink, the SSH application that comes with it. The IP address it tries to connect to can not be changed and is stuck with the old CVS repository's IP. Downloading plink from it's home site and calling from the command line still has this problem. Tortois...
I heard that if you use port 443 (the port usually used for https) for ssh, the encrypted packets look the same to your isp. Could this be a way to avoid traffic shaping/throttling? ...
When I try to use an ssh command in a shell script, the command just sits there. Do you have an example of how to use ssh in a shell script? ...
This is a follow-on question to the How do you use ssh in a shell script? question. If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return? When I try to just include the ampersand (&) at the end of the command it just hangs. The exact form of the comman...
I need to launch a server on the remote machine and retrieve the port number that the server process is lsitening on. When invoked, the server will listen on a random port and output the port number on stderr. I want to automate the process of logging on to the remote machine, launching the process, and retrieving the port number. I wr...
When I log into a remote machine using ssh X11 forwarding, Vista pops up a box complaining about a process that died unexpectedly. Once I dismiss the box, everything is fine. So I really don't care if some process died. How do I get Vista to shut up about it? Specifically, the message reads: sh.exe has stopped working So it's no...
I've had a FTP server (Mac OS X, but not the server version) set up for a while where the users are virtual, i.e. they are not actual user accounts in the server's OS, but accounts handled by the FTP server software -- to the OS they all look like the ftp user account. I'd like to retire the FTP server software and go SFTP instead. Is t...
I have a small local network. Only one of the machines is available to the outside world (this is not easily changeable). I'd like to be able to set it up such that ssh requests that don't come in on the standard port go to another machine. Is this possible? If so, how? Oh and all of these machines are running either Ubuntu or OS X. ...
When connecting to remote hosts via ssh, I frequently want to bring a file on that system to the local system for viewing or processing. Is there a way to copy the file over without (a) opening a new terminal/pausing the ssh session (b) authenticating again to either the local or remote hosts which works (c) even when one or both of the...
Are asymmetrical cryptographic keys fundamentally inter-convertible between the major key container formats? For example, can I convert an X.509 key file into a PGP or OpenGPG key file? And--assuming the answer is yes--is it "security neutral" to keep one key pair in whatever format and convert into whichever container file format is n...
What is the easiest way to manage the authorized_keys file for openssh across a large number of hosts? If I need to add or revoke a new key to an account on 10 hosts say, I must login and add the public key manually, or through a clumsy shell script, which is time consuming. Ideally there would be a central database linking keys to acc...
ssh will look for its keys by default in the ~/.ssh folder. I want to force it to always look in another location. The workaround I'm using is to add the keys from the non-standard location to the agent: ssh-agent ssh-add /path/to/where/keys/really/are/id_rsa (on Linux and MingW32 shell on Windows) ...
Is there a technical reason why IOS requires the device's domain-name to be set (via ip domain-name) before an SSH key can be generated? Is the domain-name used in any way in the generation of the key? Is there any way to force the generation of a key before the domain name is set? UPDATE: Myself (before I posted this question) and o...
I use ssh-agent with password-protected keys on Linux. Every time I log into a certain machine, I do this: eval `ssh-agent` && ssh-add This works well enough, but every time I log in and do this, I create another ssh-agent. Once in a while, I will do a killall ssh-agent to reap them. Is there a simple way to reuse the same ssh-agent p...
I set a passphrase when creating a new SSH key on my laptop. But, as I realise now, this is quite a PITA when you are trying to commit(git,svn) to a remote location over SSH many times in an hour. One way I can think of is, delete my SSH keys and create new. Is there a way to remove the passphrase, while still keeping the same keys? A...
