hello everyone. i am concerned about security to the PBX and i would like to discuss different fraud detection methods. Apart from making everything to secure the PBX (latest patches, iptables, firewalls, no outside users, strongs passwds,...) i would like to find out if there are any fraud detection techniques. As for my setup i do have a PBX running asterisk 11.4 and it has 3 sip trunks (over

hello everyone. I am running asterisk and all of my CDRs are in the default csv. the system is so limited to ram (only 256) and I cannot run MySQL or any other program to give CDRs a fancy view. at the moment the only other software running is nginx for a static webpage with guidance on the system. I do now want to move to sql or similar databases because the machine cannot handle it (I have

Hello I didn't find the answer in the ATOF 2nd Ed: When using the Record() application, I need to know how it ended: Did the user leave a message, or did he hang up? If the latter, Asterisk stops right there, while I need to run some other commands before hanging up: ======== exten => _[1-4],n,Playback(/root/asterisk_sound_files/leave_msg) exten =>

Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more

We upgraded to the latest version of asterisk (because we needed some newer features), only to find all our PIN applications accepting any number the caller makes up! I traced this to the System application completely changing the way it deals with success or failure of the program it calls. Previously, if the PIN was completely bogus, we exited with -1, which caused asterisk to jump to priority

Many of you are interested in and have used or recommended fail2ban for your linux boxes. I finally installed it on our FreeBSD server (no asterisk, hence the OT) with the help of a friend from the VoIP Users Conference and Asterisk community. After a lot of new learning about regex, I extended the actions and filters to look at our mail server, plagued by spammers - who isn't? Our server has

Hi there, I am configuring a small voicemail server and I am facing the following problem. Executing this command: exten => 1234,1,VoiceMail(${NUMBER}@test) When a user does not have a customized temporary greeting vm-intro message is played asking for the message to the user but when the user has already a temporary greeting both the temporary greeting and vm-intro are played. Basically

I got some spam emails after my last post to the list, and the emails did not seem to go through r-help. The spammers may be subscribed to the r-help, or they get the poster emails from some of the web copies of this list (nabble or similar).

Looking at http://www.fontconfig.org/wiki/TitleIndex I see it's around 99.9% pure spam. Other than the front page, virtually everything else is the moin-moin boilerplate or the hundreds of pages of spam. Even the Recent Changes & Find Page links have been overwritten by spammers hundreds of times, with the spammers fighting each other to crap on it most recently. (I restored them both

Hi guys, My site ( http://shunya.in ) recently started receiving some spam and I had ignored the issue till it became a problem, and I guess it is becoming a problem now. I looked around on suggested ways to address the problem and found two systems - CAPTCH and Akismet. I consider both of them in this email along with the reasons why I am debating using neither of them. Then I ask for your

I asked the moderators about it. This is the reply "Other moderators have looked into this a bit and may be able to shed more light on it. This is a "new" tactic where the spammers appear to reply to the r-help post. They are not, however, going through the r-help server. It also seems that this does not happen to everyone. I am not sure how you can automatically block the

hello everyone. I am running plain asterisk and I am using asterisk's internal database for: -phonebook -blacklist numbers instead of having to update the database of new entry or delete an entry, is it possible to have it in an external file such as txt? so every new entry/deletion will take place there. -------------- next part -------------- An HTML attachment was scrubbed...

Hi! This happened to me also! I just got a spam email just after posting and then in following days I got obnoxious spam emails in my spam filter. As the others, I think that there is some kind of bot subscribed to the list, but also perhaps a spider or crawler monitoring the R-Help archive and getting email addresses there. Nabble is a possibility too. > On 17 Apr 2018, at 21:50, Peter

Just an observation. I have not seen the spam you are discussing.

Hi, FYI, I started receiving spam to the email address I use only for this mailing-list, about one week after I posted a couple messages onto it. So the nut mailing-list is definitely used by spammers for email addresses harvesting :-( -- Michel Bouissou <michel at bouissou.net> OpenPGP ID 0xEB04D09C

In trying to track down how spammers are finding my email address, it has come to my attention that past postings are being archived at http://forum.winehq.org/ which reveals mine and other posters email address. I do not know who to address this to, but hopefully one of the list maintainers will see this posting. Please stop this practice (most mail lists archives do take steps to thwart spammers
