One more important thing about cron: it has no ENV set.

I think you can have more ports than 2, just make sure you pick free ones. Besides traffic from all instances can use the one and only port.

Not only solaris, HP-UX has them as well :)

By preference you should use lower case only in hostnames.

the script reads all hostnames that have 'cisco' in it from the /etc/hosts (so we are probably talking routers here) and then performs a 'ping' to see if they are 'alive' or not. This is done every 3...

Assuming you are using jetadmin to setup and manage your network printer, go into jetadmin screen and change the spooler queue options not to include the banner page etc.

Secure Copy can transfer files like the 'rcp' command but uses an encrypted 'tunnel' to send the data through. It is thus safe from intruders and snoopers. You need SSH software for it (OpenSSH) and...

You have to kill the parent process of the zombies indeed. Normally zombies are not something you should worry about as they do not take up any resources (or little) in the kernel.

You can program your scripts in Windows Notepad for all you like but it needs an incarnation of a UNIX shell to run. That does not particularly mean that you need a UNIX system, alot of the UNIX...

How about using SCP: secure copy?

You should read the release notes, readme files and installation guide of Oracle 9i software. I wouldn't expect any major changes except for possibly some kernel tweaks.

Obviously, you might want...

find / -name "file name" -print

It means that either your server is down or the FTP service is not running.

You can start by checking whether your printer was set up with an IP alias in /etc/hosts or not. If so it's just a matter of changing the entry in /etc/hosts.

The -g option stands for a numeric sort. It works in Linux, possibly the Solaris 'sort' has different options. Check with man sort which option matches a numeric sort in Solaris and use that.

The...

You could use a du on all the /home subdirectories (or where their home directories are located):


cd /home
du -k -s * | sort -k1 -g -r

Did you check the cron log to see if the command was executed and the exit code? The cron log file is typically in /var/adm/cron/log

Also check your FTP transfer mode: ASCII or binary. In this case I'd assume binary is the appropriate setting.

I am not an AIX guy but surely you can take a simple backup using standard UNIX tools like cpio or tar. Both offline and online backups are possible with these granted you put the the tablespaces in...

Obviously, RAID is there to protect you from disasters. The various RAID levels present you each a mix of disk space and safety level. If the server is critical I would definatively recommend RAID 1...

Yep, I already tried it myself, but the - excellent - info you gave can be useful to other people as well. I am not a developer so I rarely wander outside the '1m' man world. Thanks for the quote...

Mmm, let's picture this: you change exactly 1 character in an ASCII text file, thus not changing the file size. Does this change the ctime as well? I always thought not?

Another package to consider is Unix for WINdows:

You can also use:

find /search/path -mtime +30 | xargs rm -i

ctime indicates inode data change: ie. when you do chmod. chown on the file or when the file size changes. Not the contents of the...

ncftp is the nicest tool for that
