Hi Johnathan, I have found that older hardware is best supported by the more recent versions of RedHat. As Linux goes forward support for more and more devices are added to the system. I have one machine with almost exactly the configuration as yours and it is running RH8 with XWindows! Admittedly, Xwindows is slow. I mostly use the virtual text consoles because they are much more responsive/less frustrating. If I had to I would remove the default "bluecurve" GUI setup and replace the X-Windows config with one of the lightweight window managers like fwwm. I use my machine as a web server and also do some development on it. You may want to install your system without X-Windows and just use the virtual consoles. It will be more responsive that way. -- Jeff Kinz, Emergent Research, Hudson, MA. "[EMAIL PROTECTED]" "[EMAIL PROTECTED]" copyright 2003. Use is restricted.

When you are in X-windows (and I assume you are) you have to use "Ctrl-Alt-F1" to get to virtual console 1 which is normally reached by pressing "Alt-F1". You can return to X-windows from there by pressing "Alt-F7" "Ctrl-Alt-" will get you to that virtual console from X-windows, but ordinary installs will not have anything on F7 - f12 console so all you will get is a blank screen on those upper end consoles. -- Jeff Kinz, Emergent Research, Hudson, MA.

Unsubscribing from RedHat List
Hi all The problem of folks posting unsubscribe messages has existed on the RedHat install list for a long time and at a higher rate than here. It has been partially solved thru the use of an automated responder which emails an informative (and non-hostile :-) ) message directly to the person needing a clue. It does not post to the list and currently tries not to respond to the same individual more than once. I'll turn it on for this list as well. If it turns out to be disruptive I'll turn it off.

POLLIT Poll results for RedHat 8.0
The results of the POLLIT poll for RedHat 8.0 are in. In answer to the poll question : "Please rate the RedHat 8.0 release from 1 to 10 compared to Any RedHat 7.X release. 1 is poor, 5 is neutral, 10 is excellent." The cumulative rating for RH 8.0 compared to RH 7.X was 4 out of 10. Generally it appears that most of those who responded were people who had some problems with 8.0. People who did not have problems did not respond. (or there are NO people who didn't have problems with 8.0 ? ) Here are the comments: (there were three) looks & behave awful, almost like Bill's unfullfilled dumbed down, configuration options are missing Much better overall but still have some problems ie bug #77467 Anyone who wishes to respond to the poll may do so by replying or forwarding this email directly to me after appending their response to the end of the #two lines labeled "response:" and "comment:"below.

This change of directory would only affect the spawned subshell which
would die immediately, having no affect on your current process.
This would mean that your next call to system would start off in the
same directory you started in, no change. If you want the change of
directories to have any affect on the environment your script is going to
run in you must do the cd within the subshell, eg. - within your script.
OR you could use a call to "chdir" within your program (see "man 2
chdir") to change the directory your current process is actually in.
that state would then be inherited bu the subshell which the "system"
call would spawn off.

"system" actually performs "/bin/sh -c ". The assumptions inherent
here can cause problems.
The "system" man page actually warns against using it for SUID or SGID
scripts. Here is the relevant text from the "man 3 system" page:
Do not use system() from a program with suid or sgid privileges, because
strange values for some environment variables might be used to subvert
system integrity. Use the exec(3) family of functions instead, but not
execlp(3) or execvp(3). system() will not, in fact, work properly from
programs with suid or sgid privileges on systems on which /bin/sh is
bash version 2, since bash 2 drops privileges on startup.
The check for the availability of /bin/sh is not actually performed;
it is always assumed to be available. ISO C specifies the
check, but POSIX.2 specifies that the return shall always be non-zero,
since a system without the shell is not conforming, and it
is this that is implemented.
This is why I use execl. My example (posted yesterday), was cut down from a
much larger program which had a specific purpose. It can be made smaller, and
I like the way you presented the system call in your example. I recommend
using the execl call but implement the small single purpose program in the
fashion you have constructed your example.

There is a problem with this, see the man page: "man 2 execve" Near the end of the page is the following (in the Notes section): "Linux ignores the SUID and SGID bits on scripts." This means you cannot create a script based SUID wrapper. It can still be done with a very small c program.

Hi, Linux ignores setuid to root on scripts so you can't wrap
your script with another one that is setuid to root which is the first
obvious solution assuming you need your script to run with root
privileges.
Here is one solution : An executable wrapper.
# BEGIN FILE
/*
*/
#include
#include
#include
#include
#include
#include
#include
extern char **environ;
int main () {
int stat;
char * nuttin = 0;
stat = execl("/usr/local/bin/myscript", nuttin );
}
# END ###
Save this text to a file named "anything.c"
In the text file change the string /usr/local/myscript to the name of your script.
Make sure your script has #! as the first
line of the script.
compile it with "cc -o anything anything.c"
Setuid the resulting executable to suid root (man chown and chmod)
Change the ownership of the script to be owned by root. (chown 0

If you can't get access to the system at all you are worse off then when you have a less secure access. telnet is easy to turn in RH8 and in RH7.X. You could : 1. email them a script to run to turn telnet on. 2. email files to install to turn it on 3. some combo of the above. 4. "teletype" them thru it - eg. - "Now press the enter key, OK what do you see now?" You'll have to test whatever method you want to use before you do it live, Even the "teletyping" will go better if you dry run it yourself before trying it with them.

Hi All,
I remember having seen a web page which explained why its a bad idea to create
a web page for a specific browser. I beleive it was posted in this list but I
can't find the link to the article.
The basic point of the article was something like you are telling your
customers to go away if you restrict your web page to a certain kind of
browser.
Does anyone know where this page is? I tried google but got googlewhelmed.
("googlewhelmed" DEF: to be flooded with so much information that the reader
is unable to make any significant progress in processing the information.)

Re: * Span multiple partitions with root filesystem
Hi, To Nate and John Slivko who both responded, Thanks! I've used RAID before but I just didn't think about it this way.

* Span multiple partitions with root filesystem
Hi, I'm looking for information about whether it is possible to span multiple partitions with a root filesystem. I found this item in some coursework I am looking at and (No its not an assignment.) As far as my experiences with Unix/Linux have gone it isn't possible to have a single file system span multiple partitions. I have always believed it could be done, but that no one had ever implemented the necessary code to make it doable. Has this now changed? Is it now possible to have a single filesystem spanning multiple partitions? I looked in Google for Linux and didn't find anything so I'm skeptical, but I would like to be enlightened (bows eastward 3 times). Anyone have thoughts on this either way ?

On the RedHat Install List there are more folks "new" to the net so there is a more "mixed" level of posting styles. We decided to deal with it by publishing this guide: http://www.rps2.net/rhil-guide.htm The guide clarifies existing Usenet/email practices so that everyone can understand what is and is not a good way to "post" to an email list. Since the RedHat list already follows these guidelines, (hey, with just a few exceptions 'dis here is a high quality list! :-) ) anyone who wants to understand what they should be doing can read this guide to clear up any muddy areas.

This is a nice clean solution.

Hi Doug, the explicit instructions for recompiling the kernel are in the "Kernel HOW-TO" document available at : http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Kernel-HOWTO.html But you probably don't need to recompile the kernel to add your driver. You may only need to compile your driver and re-link the kernel, then re-install it. This is probably a lot less work. You may want to investigate it to see if thats an approach you can take.

Its a superbly helpful document and it can be found here: http://www.tuxedo.org/~esr/faqs/smart-questions.html This is a quote from that paper: ... "Community standards do not maintain themselves: They're maintained by people actively applying them, visibly, in public. Don't whine that all criticism should have been conveyed via private mail: That's not how it works. Nor is it useful to insist you've been personally insulted when someone comments that one of your claims was wrong, or that his views differ. " Also I note that the tone of that suggestion was pretty polite. David is clearly an Ok guy and probably just needs to know that he should post in text only. There are very good reasons for not using html when posting to an email list some of which are explained below: Quoted from the RedHat Install Email List Guide: Email formatting is very simple. Plain text, around 72 columns wide. Please avoid posting in HTML or MIME. Here's why - As the author of an email you have no idea what kind of email client, (the program email gets read in), the people who get your email will be using. This means there is no way of knowing if their email program can display your email. If it can't - they can't help you. With the new wireless devices and PDA's that are becoming popular, (yes, with Linux too), this problem is becoming even more of an issue. Plain text is the only email format you can use that guarantees it will readable by all the people who receive it. Many of the most helpful and knowledgeable people on this list won't even read your email if its in HTML or MIME format. Sorry, its nothing personal, just too much of a hassle and a security danger for them. (HTML|MIME mail can have embedded info gathering or virus dangers). Many people around the world have metered internet access where they pay for each byte of data they receive, including their email, on a per-byte basis. MIME and HTML formatting increase the size of messages but don't add any information to them. Many Linux users won't even open HTML/MIME email messages because of the extra security dangers and work involved. Because of these issues you should not send HTML or MIME based email to this list. (and you should avoid it whenever possible in general). As a further benefit - not using HTML or MIME when you don't have to will actually speed up how fast your email goes out. Whats that you say? Your email program does the HTML or MIME formatting automatically and you don't know how to stop it ? . SNIPPED Section IV.

It is a built-in bash shell command. The preferred way to set it, is to add a umask command to the .profile or .bashrc file in your home directory. To change it system wide there is a file in the etc directory hierarchy where the default values for user shells are set. Its is "/etc/bashrc" but I recommend not setting umask there. Its current default value is probably the best one for system wide use. For specific groups of users you may want a slightly more open value but it shouldn't be needed most of the time. >From the bash man page: == umask [-p] [-S] [mode] The user file-creation mask is set to mode. If mode begins with a digit, it is interpreted as an octal number; otherwise it is interpreted as a symbolic mode mask similar to that accepted by chmod(1). If mode is omitted, the current value of the mask is printed. The -S option causes the mask to be printed in symbolic form; the default output is an octal number. If the -p option is supplied, and mode is omitted, the output is in a form that may be reused as input. The return status is 0 if the mode was successfully changed or if no mode argument was supplied, and false otherwise. == > THX > > Shmulik > > > > -- > redhat-list mailing list > unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe > https://listman.redhat.com/mailman/listinfo/redhat-list > -- Jeff Kinz, Emergent Research, Hudson, MA.

try compiling it with g++ instead of gcc. Its a C++ program,
not a 'C' program.
Leastways, it works on my system. RH 7.2
cat foo.cpp

The error says it all: it's spawning processes faster than the threshold
allows and closes service for 10 minutes (and yes, it will come back if you
let
it sit there for awhile).
>From the man page ("man 5 inetd.conf"):
The optional ``max'' suffix (separated from ``wait'' or ``nowait'' by a dot)
specifies the maximum number of server instances that may be spawned from
inetd within an interval of 60 seconds. When omitted, ``max'' defaults to 40.
The 40 connections/minute acts as an emergency brake to limit the damage a
DoS'd service can do. However, if you run a busy mail server, it is possible
to
exceed 40 connections/minute of legitimate traffic. If you see this warning
in normal operation, up the limit. In inetd.conf, look for this line:
pop-3 stream tcp nowait root
change nowait to nowait.## such as:
pop-3 stream tcp nowait.80 root

I know Perl is much better > and gives more control, but I want to do it first en bash script just for > fun :) Any suggestion? The best tool for this type of work is "expect". It is explicitly designed for creating scripts that allow one program to interact with another. The problem with your script above is that it send all of your text to the smtp host immediately without waiting for the SMTP program to get ready for it. As a result the SMTP program drops all your text on the floor. Here is an example of a program which gets the count of messages for a user on a pop host. #!/usr/bin/expect # turn off trace output log_user 0 # launch the telnet program, specifying host and port number eval spawn telnet -l myname pop.mydomain.com 110 # Wait until the pop host sends back the ready string expect "ready." # Send the login sequence to the pop host send "user myname\r" # Wait for the pop host prompt for a password expect "PASS" send "pass mypassword\r" expect "welcome" send "stat\r" expect "+OK " # Yes -expect can use wildcards and can even use a "case" statement to respond # to variable output in variable ways. expect -re "\[0-9]* " # Save data for some future use. set answer $expect_out(0,string) # Send_user sends the text to the user terminal, instead of the interacting # program. send_user "$answer \r\n" expect -re "\[0-9]*\r\n" send "quit\r" expect "signing off" exit # # -- Jeff Kinz, Director, Emergent Research, Hudson, MA.

What DOES the 1.28 reflect? FDrom the man page: uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes. so from your output you had a utilization of 128% for the past 1 minute, 109 % for the last five, abd 106 % for the last 15 minutes.

(&& = AND, || = OR ) So the only part you have to look at is: true || echo 3 && echo 4 && echo 5 Which is better understood as : ( true || echo 3) && (echo 4 && echo 5) or (X) && (Y) As soon as "true" is encountered in (X) it stops evaluating that part of the statement, (so the "echo 3" is never evaluated), and goes to the && separating the two paren groups. Since its an && statement the (Y) has to be evaluated to determine if the entire statement is true. Since the (Y) expression is also an "AND" statement both subexpressions "echo 4" and "echo 5" have to be evaluated. Next question - How does bash determine precedence in an expression ?
