Consider using a 2.4 kernal so that you can take advantage of iptables which is easier and more powerful. You can do a lot of things in iptable much more simply than ipchains, and since it is session...

It's not an excutable file. It's a text file so you need to be able to read and write to use it as a history file.

Sorry above was for Linux and doesn't work on my Solaris box. This works on Solaris

ls -1 | grep -v `ls -1 *.Z` > templs ; compress `cat templs`;rm templs

Try:

gzip `ls -I *.z|cat`

I was unable to get this to work with compress for some reason.
If you don't mind using gzip insead of compression this is workable.

Certainly points to the accounting solution once again, espcially if you have a savy user who knows he is being monitored in this way. Of course, the user would need to suspect that he was being...

True, this is also true for SSH using a public key with a null password or equivalence file. You are basically relying on the security setup of you local computer to shield your remote computer.

Actually, no offense taken, I just realized that I didn't explain enough.

As mentioned it was not the most secure decision. Perhaps I should metion that these were completely secured boxes and on an internal, network that was not accessable from outside. Also, even if...

To adjust your resolution on Red Hat try <b>setup</b> which is a front end for a few setup programs such as <b>XConfigurator</b>. You might have to use this outside of X for best results. As for...

Does <b>boot -s</b> at the <b>ok</b> promopt work in SCO? I know that this works to boot a computer running SUN Open Boot, which in my experience is just Sparc hardware. Does SCO use this convention...

There is a way you can do this with rlogin, telnet, ftp, ssh by writing a script in Expect. Expect if a great way to automate any task, and you can write an extremely basic login script in Expect...

I never liked Hyper-Terminal for use as a video terminal (e.g. vt100). I would look into something like Tera Term if you can't get Hyper-Terminal to work....

Usually if the login shell cannot be found (eg. /bin/noshell) then the account will not be logged in. Check to see that /bin/bash is not just a link to /bin/sh. You might want to type /bin/bash when...

From the man page on Solaris 8:

<b> Users: Access to crontab is denied:

o if /etc/cron.d/cron.allow exists and the user's name
is not in it.

o if...

Thanks, that could be it. I don't remember the file permissions exactly since it's been a while. I do remember the Unix servers we used had no problems so I will try this next time.

I am aware of at least 3 major problems with OpenSSH recently. These I believe are 2.x versions. 1.x versions have problems associated with SSH1 which have been addressed by SSH2, but the OpenSSH...

Just a quick note on ftp from Windows to Unix:

If you need to copy ACSII files make sure your ftp is in ASCII transfere mode and not binary or you will get the ^m character at the end of each...

You can't really have a person updating a file like .bash_history and then disallow them to edit it (both actions require write premissions). Unfortunately Unix doesn't have as finely granuated file...

I found in some cases even with a .rhosts file on Red Hat that it was still prompting for user name and password which was a major problem for automated transfer programs that I needed to run rcp. If...

I would advise against telnet at all costs if it can be avoided. The username and password get transmitted in clear text. Try ssh2 or even ssh (but ssh and openssh have problems with security) if at...

The problem you just described often happens when you tell Unix/Linux that your hardware time is GMT rather than local time. CDT is -5 GMT so this looks suspecious to me, try changing your hadware...

Check out the sound HOWTO's and MINI-HOWTO's at the linux documentation project <i>www.linuxdoc.org</i>. I had the same problem and found the answer there. Basically, my BIOS settings had to be...

I just had a similar problem on SuSE Linux. The man page makes reference to an allow and deny file. On my system they are located at <b>/var/spool/cron</b> The deny file is supposed to deny only...

You should still be able to manually install your 3Com card. Check your manual that came with your OS and look for the <b>modprobe</b> command for your particular adapter. This will probably be...

Didn't realize <b> > $file</b> was possible. Thx
