What is the point of allowing ssh-keygen to generate empty passphrase keys when it is not recommended to use such keys for remote login? What situations would such keys be useful for?
The passphrase protects the key in its storage on your local computer.
Even without a passphrase, a key is still better than a password, as it can only be "stolen" if someone has physical access to your computer (or at least some kind of network access to the files on your computer), whereas a password can be brute-forced (or leaked from any number of places in case you re-use passwords).

I've set up a TLS server in Go using a custom generated certificate/key pair. Is there an easy way for me to test that the content of my HTTP requests to this server is indeed encrypted when it gets sent out over the network? For my own sanity I'd like to compare and contrast the content of the packets when I use TLS vs normal HTTP.
You can use a sniffer, here are two: Charles Proxy, it has a 30 day free trial period and is easy to use. Or WireShark, it is free and you will hate using it.

I enabled AD authentication for my Linux cluster via SSSD service. One side effect is I'm able to do SSO for the cluster now, but it works for some accounts and doesn't for the others. For example, I have two Linux boxes they all registered to the domain. And two accounts are a domain user, and both have been permitted to access the Linux boxes. One can ssh from one box to the other, but the other account doesn't. Default configures the SSSD and SSHD. I don't know what I have to check?
All right, I figure it out, I sudoed from one account to the other, so there are no password in the keytab for the second account, that's why the SSO doesn't work.

I would like to know if the public key depends on the used account. In other words, do I really have to use the same account on the server and the client when I add my public key (id_rsa.pub) in authorized_keys on the server?
Thanks.
The accounts don't matter. All that matters is that the client key is in the server account's authorized_keys file.

For our company I want to setup a file sharing service such as Dropbox but on our own servers for our corporate information.
It must be only available for employes of our company.
Please suggest me software package.
I suggest you try http://owncloud.org/.
That's what we use in my company and it is quite convenient to sync our working files (similar to what dropbox do), and to share files as well.
Have a look at arXshare (http://www.arxshare.com). You can install it on any server with PHP, it is easy to setup, and it does not require any database and is very lightweight. Furthermore, it does end-to-end encryption, so your shared files on the server are useless without your password.

I'm trying to script a backup system for several servers, some Windows, some Linux. I'd love to be able to use rsync but I can't (at least not in all situations, since some servers I can't install rsync to, and some are Win servers).
I've tested with wget in FTP mode with the "timestamping" option, and it seems to work pretty well regardless of platform. Are there other options that may be more robust/reliable, that will do incremental backups regardless of platform?
Thanks for any ideas
You might try Unison.

You definitely want to have a look at rdiff-backup. And Server Fault. ;)
