SELECTing a mailbox has nothing to do with FETCHing messages, so above does not make much sense. I don't know dovecot's code, but I

Excellent point. I like it! It can get a bit confusing with round-robin DNS, which can give multiple responses. > But there is that initial

If I want to specify for LAN addresses that I don't want to deal with host keys, how do I do that? Understanding the risks, knowing almost everyone will say not to do this - it's a horrible idea, but deciding I want to do it anyway. Tired of having to remove entries from known_hosts with the multiple VM's I have that often change fingerprints, and am willing to live with the risks.

Thanks for clarification. One question though: As far as I have tested openssh, it logs every unsuccessful authentication attempt on the very moment it becomes unsuccessful, not after the connection is closed (after timeout or when reaching max auth attempts). Is this true or not even for this attack or not? Because if it is true, if there is a IDS system that bans IP after X failed logins,

I read an article today about keyboard interactive auth allowing bruteforcing. I'm afraid I have minimal understanding of what keyboard-interactive really does.

Hi all, authentication forwarding depends much on the environment it is used in, but generally on shared hosts it is considered insecure, as this documentation and common sense tell us: http://unixwiz.net/techtips/ssh-agent-forwarding.html Anyway, I have an auth forwarding security enhancement proposal. I hope I am not duplicating someone else's words/thoughts, please notify me if this is

Hi, is there a particular reason why this feature is "user" based and not "user-pubkey" based? What I mean is that it works for installation with small number of pubkeys per user. But imagine i.e. a GitHub scale - all users logging in as user "git". On each auth request all the keys from database would be fetched and feeded to OpenSSH. Now I am only asking this out

Hello, I haven't found anything useful googling around so I decided to ask here. I have a Linux server running Samba on 100Mbit/s ethernet. If I connect to it using WinXP, mount some share and download files from it it reaches about 9MB/s transfer rate. Using FTP gives even higher transfer rates. BUT when I use linux to connect to (linux!) server, mount shares and download files then

Hello everyone, I would like to ask you for advice on how to approach (or solve) this particular problem. I use Slackware Linux and compile Openssh from source. I prefer to compile it statically so it doesn't get messed up if I update openssl libraries. Up until now this approach was working OK for me. Lately I have been challenged with Slackware64 installations and I have come across a

You need to disable ?ChallengeResponse? (aka keyboard-interactive) authentication, not password authentication, to protect against this attack.

Hello everybody! This is probably going to be a classic question but I cannot find a decent answer on net. I have samba server set up and the following things work flawlessly: - iperf shows 92% link utilization - FTP/SCP/HTTP transfers work in 10MB/s range. However, when I mount samba share with linux client (mount.cifs) the link utilization cannot bypass cca 33%. Transfer speeds constantly

Perfect, thanks. This winds up working for me (as far as I've tested so far.) Match exec "ping -q -c 1 -t 1 %n | grep '192\.168\.'"

How can I ask ActiveRecord to make it''s "has_many" code to work on some arbitrary relationship between two tables? ie neither field is a primary key The situation is that I am writing a Postfix management application and one of the tables to manage is the "alias" table. My primary key in the "mailbox" table is "id", but the alias table is just

Hi again, puppetd started to hang with 100% CPU usage all of the sudden. Strace just keeps repeating these 2 lines: --- SIGVTALRM (Virtual timer expired) @ 0 (0) --- sigreturn() = ?

Hi, Is there a way in Asterisk 11 to use a single voicemailbox for multiple extensions while still hearing each extension's individual greeting? Use case: someone has 2 numbers and wants all voicemail messages for both numbers to end up in one mailbox. So when dialing 1234 and NOANSWER you would hear "the person at extension 1234 is unavailable" and the message would be stored
