Is 17 dB ERLE normal?
...ing PJSIP and Speex Speech processing API on an ARM platform. Currently we have spent about a month on getting the AEC to work properly and we have worked through the most common causes of problems (such as clock drift, synchronization problems and non-linearity's in echo path). Now we achieve ERLE of about 17 dB which tells me that the AEC is doing something however we are subjectively not satisfied. Some references of ERLE taken from this mailing list tells that 15 dB [1,2] is not good enough and that 30 dB would be fine [3]. My question is if 17 dB is in line with what is expected from t...

Octasic echo cancellation
Hi, I'm currently testing SoftEcho, an echo cancellation software for Asterisk from Octasic. I noticed an important increase of the quality of my coms, but I still have a few echo problems. There is an ERL parameter which corresponds to an initial ERL value probably to optimize the echo training or something in that kind. Is there a way to monitor, using one of the zttools, the instant

Default password hash
We still have MD5 as our default password hash, even though known-hash attacks against MD5 are relatively easy these days. We've supported SHA256 and SHA512 for many years now, so how about making SHA512 the default instead of MD5, like on most Linux distributions?

ERLE Measurement
Hi, I was wondering if someone can share their experiences about how to measure ERLE in the SpeeX AEC. I have been trying to understand some of the implementation in mdf.c, and have been using the RER ( Residual Error Ratio) as an estimate of the performance of the echo canceler. Any suggestions would be much appreciated. Thanks, Bud -------------- next part -------------- An HTM...

OpenPAM/SSHD privacy hole (FreeBSD 9.2+ affected)
Hello, I found that in the new FreeBSD 9.2 (probably in 10 also) updated OpenPAM sources. The big embarrassment was in pam_get_authtok.c. The problem is that even without a valid SSH login it's possible to know the server's hostname. az at az:/home/az % ssh 1.2.3.4 Password for az at real.hostname.com: Changes made by "des":

HEADS UP: OpenSSH 3.8p1
Take the usual precautions when upgrading. Also note that I have changed some configuration defaults: the server no longer accepts protocol version 1 nor password authentication by default. If your ssh client does not support ssh protocol version 2 or keyboard-interactive authentication, the recommended measures are: 1) get a better client 2) get a better client (I mean it) 3) get a better

Strange behaviour of R graphics copied to PowerPoint
Hello, I am using R to create graphics, especially to plot time series charts. These charts are then copied as metafiles (for best quality) to a PowerPoint presentation and then saved to PDF (via the "Save As" dialog"). Attached is two pictures. The first picture shows how my chart looks like in the R Graphics window, and the second picture shows how the chart becomes after saving

[PATCH] php: add a simple bindtests test
Generate a simple bindtests test for the PHP binding, so it is possible to easily test all the argument types. Unlike the bindtests for other languages, optional arguments are not tested, due to the limitations of optional arguments in PHP (or maybe they way we implement them). --- .gitignore | 1 + generator/bindtests.ml | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++

loginmsg bug
Cf. http://seclists.org/fulldisclosure/2008/Jul/0090.html This Mrdkaaa character claims to have exploited this, but does not say how. The issue is that if do_pam_account() fails, do_authloop() will call packet_disconnect() with loginmsg as the format string (classic printf(foo) instead of printf("%s", foo) bug). The stuff that do_authloop() appends to loginmsg is harmless (the user

Collecting entropy from device_attach() times.
Hi. I experimented a bit with collecting entropy from the time it takes for device_attach() to run (in CPU cycles). It seems that those times have enough variation that we can use it for entropy harvesting. It happens even before root is mounted, so pretty early. On the machine I'm testing it, which has minimal kernel plus NIC driver I see 75 device_attach() calls. I'm being very careful

SSH Command Line Password Support
Hello, I am interested in an ssh that is not interactive in requesting the password, i.e, whereas I can specify the password in the command line when calling SSH. I have wondered how such a feature has not been included in such a good client, as it seems there are many (and I have searched for this) people require this capability for their scripts/automation. I understand the possibility of

I copied the appropriate binaries and libraries into my chroot, I can chroot -u test -g test /home/test /usr/local/bin/bash and it works perfectly. So now I am trying to get the pam module to work.

nx-bit and TPM
Hello, I'm was looking through handbook and wikipedia and it appears FreeBSD doesn't support hardware (nor software) nx bit. There also doesn't seem to be any support for TPM (Trusted Platform Module). I was wondering if it is due to a general lack of interest and/or personal preference (gcc?) or are there other issues. The reason I'm asking is I'm currently doing a MSc degree
