Hi list, i noticed from the cli my asterisk box is accepting unauthenticated calls how can i prevent this?

Dear OpenSSH developers, a publicly accessible sshd on port 22 generates a lot of log clutter from unauthenticated connections. For an exemplary host on a university network, sshd accumulates 5~20k log lines on a single day (more than 90% of the total amount of syslog lines). That is despite the host having a restricted configuration (no SSH password authentication, firewall rate limit for

modern syslog daemons (including rsyslog, which is default on just about every linux system) allow you to filter efficiently on the message contents, not just the severity, so you can opt to throw out the messages you don't want. I advocate for a slightly different way of dealing with it, filter these messages from your main logstream, but put them into either a script directly, or a

Hello, given the 2015 revision date, I was curious if anyone can confirm https://wiki2.dovecot.org/Timeouts is still accurate where the 'before login' IMAP timeout remains hard coded? We're having an issue where blocks of IP's from China and similar locations are crawling IP ranges trying common login credentials, and hanging the connections open in the process. We have clients

I am seeing a recent increase in SSH harvesting attempts and brute forcing in the log of my system. I'm interested in opening up some discussion around what OpenSSH can do itself to counter measure against: * DoS attack where too many unauthenticated connections are open. I'm not interested in stopping the professional saboteur but the casual script kiddie (to use IRC terms) from

Hi, I've configured my samba server as a PDC and joint some windowsXP clients to it. So far so good. However I'm able to login into windows even when the domain controller refuses to authenticate the user. The user is not able to access the shares but can use the local machine. How can I prevent windows to login the user locally when the domain controller refuses authentication? thankz,

In your sip.conf file allowguest defaults to yes. This means that anyone that can reach the SIP ports on that system has access to make unauthenticated calls, by default. The administrator actually has to go in and turn it off to prevent unauthenticated SIP calls (in whatever context [general] points at). Does anyone else agree with me that this is a poor default? I'd like to see the

I need some help understanding SIP dialog. Some actor is trying to access my server, but I can't figure out what he's trying to do ,or how. I'm getting a lot of these warnings.

I am having an issue adding new clients to puppet. The master is not accepting connections from unauthenticated clients, even though my auth.conf that worked with v3.1.1 has not changed. If I test ssl via curl -k, the puppet master returns "can''t convert nil into String" to the client. The http log on the master shows a 400 return code. Also note, I''m using

To radically cut down on SSH log spam you can also hide it completely behind a firewall, and allow access only by some port knocking sequence. I quite like having a process listen on port 53 and wait for a dns query containing a totp string to grant (temporary) access; that's a 2fa, and doing a "host 123456. my-ip" is easily automated in a shell script as well...
