I just tried booting SUSE 11.0, but the system stops at the point it shows "initializing random number generator". I have left the system running at that point for almost 2 hrs, with no way to get past that. System isn't locked up. It has never done this before. How do I fix this?I have also tried failsafe booting, but it stops at the same spot also.

View 7 Replies View RelatedI am trying to make a random sentence generator in perl. So far I can loop it x times to make a fixed quantity of words, but I don't want to do that. Or I can let it go on until I hit ctrl-C :/
I want to have it so that when it reaches a word with a sentence terminating punctuation mark it stops.
My attempt to do that was with:
This is doing the woooosh text until ctrl-C thing...
Now however I am not sure how I can cut off everything after the punctuation mark (when it exists).

Quote:
SHELL=/bin/bash
SUBJECT=`formail -xSubject:`
FROM=`formail -xFrom:`
SUBJECT=`echo $SUBJECT | sed -e 's/ /-/g'`
FROM=`echo $FROM | sed -e 's/.*<//g' | sed -e 's/>//g' | sed -e 's/@/AT/g'`
STOREFILE=20`date +%y-%m-%d_%H-%M-%S`_${FROM}_${SUBJECT}_${RANDOM}${RAMDOM}
it works fine except ${RANDOM}${RAMDOM} and I do not want to use mktemp command .
Not only that but I need tons and tons of them generated, and I need it to be totally random each time.
Code:
matthew@mvm:/h/misc> cat a
#!/bin/bash
for i in {1..5}; do
echo $RANDOM
[Code]....
There you can see that it is the same number. It does that every time!! Grrr. The strange thing is each time I manually type [or copy & paste] it into the terminal, it gives random [not static, like I am getting from my script] results.
The reason I want this is because I am making a script where this line will randomly go up or down [depending on if the random number is 1 or 0].
when we type mpd & to bring up ring on a single nodethe output is a random number,like this:>>mpd &>>[1] 5450anybody knows what is this resulting number?ps: i dont think its a port number because when i type >>mpd -eits prints out the port number mpd takes

I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net.

As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

Just noticed this, when I am logged into OpenSuse 11.3 under my default user (autologin) I have 3 of the same user logged in, eg when I run top it shows 3 users and when I run the users command it shows the same user 3 times. Is there any reason for this? Do I need to investigate this at all?

Is it possible to get a file descriptor from the major and minor number. If so, how can this be done? I am trying to see if a port(eg ttyS2) is opened without using the fdopen or open or fopen functions. is there a way to get the file descriptor of file or port that as already been opened, without using the functions I mentioned above. These functions reopens the port. I am trying to avoid that.

View 1 Replies View Relatedi could find is crunch2.9 password generator but at the moment it does not suport the function that i am looking for. My aim is to generate : 10-character combinations of the following characters (lowercase) 23456789abcdef with no more then 3 same letters repeates no metter side by side or within one line (sequence) so lets say
abcdef1234 accept
fabcde1234 accept
ffabcd1234 accept
which is probably permutation with repetable string ( where abc is not equeal to cba etc .so ti speak position does metter)
fffabc1234 not acceptable -----(3 same characters)
ffabcf1234 not acceptable -----( 3 same characters event thought not side by side)
so generally we dont want 3 same characters apper in same line.

I'm recompiling my kernel on a dell latitude c600 running lenny as I type, and it's taking forever, so far upward of 4 hours.I think I'm getting drivers for ever piece of computing hardware since the univac So I googled "a kernel conf creator" and got [URL]... Its a nice, clean method for finding what hardware your using... you just run lspci cpuinfo make xconfig and put in all the info yourself. So I was thinking: this is exactly the kind of dull, repetitive behavior that computers were made for. Is there a program that can find my hardware info, and make the.config itself, with very little user input?Or should I reinstall debian on another partition and steal the .config from it? Or should I man it up and do it myself?

I have never worked with databases before, and would like to create one to be a "workout generator." i.e. have a name of workout, list of equipment, list of exercises, and instructions. Then be able to search by any of the above parameters (for example dumbells and pullups) to get a list of options. I assume a relational database is my best option, but my brief looks at SQL etc they seem quite complicated. A GUI frontend and good documentation are highly desired. GTK is also preferred.
