Hi. I've been playing a bit with "use sound card as an entropy source" idea. This simple program does what I wanted: http://people.freebsd.org/~pjd/misc/sndrand.tbz The program is very simple, it should be run with two arguments: % sndtest /dev/dspW 1048576 > rand.data This command will generate 1MB of random data. With my sound card: pcm0: <Intel ICH3 (82801CA)>

Is anyone successfully using some sort of hardware crypto solution to combat the overhead of SSL in http transactions?

Hi guys We at ZKS were also interested in yarrow under unix. However the implementation that counterpane have on their web page doesn't correspond to the paper -- it is a pretty different design. Also the windows code is hairy in the extreme -- I decided to reimplement it from scratch from the paper, rather than try to look at that windows code too much (yeuch!). And in writing from the

Over the holidays, I intend to finally rid portable OpenSSH of the builtin entropy collection code. Here's what I intend to do: When init_rng is called, we'll check OpenSSL's RAND_status(). If this indicates that their PRNG is already seeded, we'll do nothing. This effectively detects platforms which have /dev/urandom (or similar) configured into OpenSSL. If OpenSSL isn't

What would be a good POP daemon to use? I know there are a few in the mail ports. Are they any good? What I mean by good is 'secure as possible' (is there really such thing as being totally secure / invulnerable?) Cheers

Hi, I was looking at the crypt(3) manpage, and I'm having a hard time figuring out what the allowed characters are for the salt in md5 and blowfish encryption. For DES, it clearly states that only numbers, letters and digits may be used. Does anyone know the rules for md5/blowfish salt characters? Thanks, Charles -- Charles Sprickman spork@inch.com

Now that ssh-rand-helper has been segregated into a separate program, I'd like to revisit an old question about its entropy gathering. - would it be desirable to make it possible for ssh-rand-helper to fall back to external commands if PRNGD cannot be reached, instead of choosing one or the other at compile time? - When using PRNGD, the program gets 48 bytes of entropy from PRNGD,

Using OpenSSL, is there a preferred/recommended rate of rekeying an encrypted stream of data? Does OpenSSL handle this for developers behind the scenes? Does it even need to be rekeyed?

In FreeBSD 5.x only telnet/telnetd works 'out of box' with kerberos. Why ftp/ftpd, ssh/sshd and cvs do not support kerberos ? Thanks!

I'm constructing a Web server which may require restricted areas of the site to be used from public places where a password might be sniffed. The damage that could be done by taking snapshots of the content from one session with a spy program is minimal. What the owner of the server does NOT want, though, is to allow unauthorized parties to gain unfettered access by stealing the password via

It seems that glances is not in EPEL for CentOS 8. Is that coming at some point, or has it been deprecated in favor of some other tool?

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

Hello, I am interested in a port of OpenSSH to the Win32 plattform, using Cygwin for a start. Is anyone already working on it? Regards, Marc

I was doing some regression testing in 5.5: Specifically testing booting up a 'virgin' hard disk from a clean install. I was testing what happened if the 300 second timeout happened vs hitting <return> for 'fast+insecure' startup and punching in a bunch of random garbage. I found that for some reason, on a 2.4Ghz Celeron, the 'sysctl -a' and 'date' seeding

I''d like to be able to dynamically read external configuration files within a dtrace script. I know dtrace allows inclusion of C header files but only at the preprocessing stage. What we need to do is dynamically enable/disable probes based on current application settings. I''d rather not have a bunch of independant scripts running and being started and killed whenever the

Nico-- SSH is trying to "get entropy" by taking the (somewhat-deterministic) output of a bunch of system commands, on those OSs that don't provide a /dev/random or its equivalent. The commands that it uses are in /etc/ssh_prng_cmds or its equivalent on your system; just comment out any of the lines (and stop/restart SSHd) in order to change which system commands are used as inputs

Greets to all, Recently, I was given the task of setting up a Samba server where I work, to accept domain logons for Win9x machines and also NT-based machines, which consist of mostly XP boxes, with a couple 2K machines as well. This domain would be replacing an older one, that was using a very out of date Samba (from RedHat 6.1) that couldn't do XP/2K at all. The new one is from
