dnssec-keygen on slackware
Hello,
I have a slackware system that I am been having issues using the ISC bind 9.3.1 dnssec-keygen utility.
On my REDHAT ES 3.0 box I have the following strace
Now that one works. However when I go and do the same on my slackware box I get the followingCode:execve("/usr/sbin/dnssec-keygen", ["dnssec-keygen", "-a", "HMAC-MD5", "-b", "512", "-n", "HOST", "chris"], [/* 20 vars

I have tried to use the standard packages on Slackware and compiled my own but neither resolved the issue. Im at a loss I have openssl on both systems and I have not had any problems in the past using other key gen software products.Code:stat /dev/random File: `/dev/random' Size: 0 Blocks: 0 IO Block: 131072 character special file Device: 3001h/12289d Inode: 12266 Links: 1 Device type: 1,8 Access: (0444/cr--r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2005-05-18 13:22:31.000000000 +0100 Modify: 2005-05-18 13:22:31.000000000 +0100 Change: 2005-05-18 13:22:31.000000000 +0100
Can anyone shed any light on this!?
Further information about the bind config
The BIND 9.3.1 compiled and setup in a chroot environment in the jail I have these files in the dev folder
root@localhost:/named/dev# ls -al
total 0
drwxr-xr-x 2 named named 144 May 18 13:49 ./

crw-rw-rw- 1 root root 1, 8 Jun 18 2004 random
crw-r--r-- 1 root root 1, 5 May 18 13:49 zero
I felt that should be enough but I maybe missing another node. However Im not seeing any alternative dev calls. But I may have missed something!

Well, I've looked over what you've got there pretty carefully. Apparently on slackware, the tool is having trouble reading from the /dev/random device as you've probably guessed. On redhat, it sets the file handle to non-blocking and starts reading away. On slackware, it sets the file handle to non-blocking and attempts a read but gets the EAGAIN error which means the handle is not yet ready to be read. Appropriately, the slackware version uses the select() function to wait for readable data for infinity. Apparently, the data is never readable from /dev/random.
The device that is being used is /dev/random. Not the named/dev/random that is in your chroot. The permissions are properly set, which was proven by the successful open on slackware's part. The file also has the correct nodes defined for it as was proven by the successful requirements check made by the slackware on this line:
stat64("/dev/random", {st_mode=S_IFCHR|0444, st_rdev=makedev(1, 8), ...}) = 0
That's how you stand. You may have already known all this. At this point I would be writing a program to see if I can read from /dev/random. If not, then I would be looking at the kernel why I am not able to read from /dev/random.
Course, I'm not an expert on special character files either.
This document discusses EAGAIN and the random device:

random number generator
Hello,
I feel that is the problem. I can use /dev/urandom without any problems. However If I try and use /dev/random I get nothing. as seen by this
vsCode:dd if=/dev/urandom of=/root/random-seed count=5 5+0 records in 5+0 records out
the /dev/random one was ctrl c'ed after 5minutes with no luck. I can type cat /dev/random on my laptop but not my server. The device nodes appear to be correct based on man urandom that shows the minor number should be 1 and the major number 8.Code:dd if=/dev/random of=/root/random-seed count=1 0+0 records in 0+0 records out
If i go and view the /proc/sys/kernel/random/*
On my Laptop
On my Server with the problem I getCode:/proc/sys/kernel/random$ cat entropy_avail 3375
Any ideas?Code:cat /proc/sys/kernel/random/entropy_avail 3

According to the definition of entropy here:
http://www.answers.com/entropy&r=67
I'm assuming that your entropy level is an indicator of how random the output is from the random device. I wouldn't think having a low value like 3 would prevent the device from being read, but then, as I said, I'm not an expert on special device files. I just know how to look things up mostly.
I do not know how to fix this problem. I'm mostly good for programming or BIND related issues.
