I don't remember exactly... I think that the message in the log file
appears each time I log-out/log-in. Recently I uninstalled the
portmapper RPM package and some others which I thought are not in use.
After that I noticed that message in the secure log file.
I start up Linux at init level 3. It means no graphics until I type
"startx".

As with most OS upgrades (as the one you're facing), I'd rather do a
backup, wipe the disk and start from scratch with the new distro.
You could leave /home and possibly others in place (I usually do) but
it's all up to you.

Try reading the Ethernet HOWTO, the Net HOWTOs, and try the command

Subject: Problems setting date
Date: Sun, 13 Aug 2000 13:27:23 -0500
I'm using RH6.2, and I have a real problem getting the date display sorted.
If I set the date using
date -u -s 'Sun Aug 13 17:23:00 GMT 2000'
Sun Aug 13 17:23:00 UTC 2000
that seems to work fine. But my date always displays in EDT, and all
applications pick that up. I want it to display in GMT (actually
GMT+1, or BST - British Summer Time)
[root@lake log]# date
Sun Aug 13 13:23:15 EDT 2000
timetool doesn't do it for me either. Any ideas?
many thanks,
Dave

First, always start crontab by typing crontab -e. To disable the automatic
mailer, include the following line as the first line of the crontab:
MAILTO=""
Then exit out of the editor to install the new crontab. It is not
necessary to restart the cron daemon. To verify the contents of the
crontab, run crontab -l.

Make sure that you also install the mySQL client which includes the
mysqladmin binary. The server does not include such functions. Also, make
sure you run db_install in your /local/bin directory to init the databases.

Date: Sun, 13 Aug 2000 16:29:51 GMT
If sendmail hangs, this is almost always because it cannot establish a dns
query of the machine's hostname. A workaround that works on some systems
is to include the "order hosts,bind" line in your /etc/resolv.conf and/or
add your ip for localhost as the primary DNS server and provide a local
loopback for that ip query.

Subject: Network speed problem
Date: Sun, 13 Aug 2000 16:36:14 GMT
Hello!
I wonder if anyone could help me about a problem i have with my RH6.2 box.
The problem is that the speed of the network is slow. If i copy a huge file
from my NT or
Win98 to the Linux box it takes very long time to complete that. For
example, a 35 000 KB file take over 20 - 30 minuts! I have measuring the
speed with Iptraf and that shows a total rates off between 80 - 120
kbits/sec. I use a 3Com 3C509-TPO card.
Anyone have an idea what the problem could be?

I am planning to install RedHat in my PC, which has installed Win2000. To
avoid incompatibilities. What should I notice?
Also, which one (RedHat or Win2000) should be installed first if I would
like to install them in the new PC?
Thanks.

That will only work if you want a generic DOS MBR. What if you want to recover
the MBR after Linux has been installed and overwritten the MBR to use with
LILO?

Swapspace is (usually) kept on a partition instead of in the filesystem
because doing so results in a performance increase. The swapper doesn't
have to deal with the filesystem and can just write to the raw disk, you
see... Since partitions must have a fixed size, that *can* mean that
your swap space is fixed in size.
Naturally, it doesn't have to. You can do this to add 128M of swap to a
system that needs it:
# dd if=/dev/zero of=/swapfile bs=1M count=128
# sync && sync
# mkswap /swapfile && swapon /swapfile
Remove it by doing
# swapoff /swapfile && rm /swapfile
You *can* have a Linux box without any swap space at all. It's a really
bad idea on machines with < 128M, and it's not really a good idea even
on machines with a lot of RAM. Basically, if there's swap space, things
that don't get used will be shuffled off to the swap, leaving more room
in RAM for heavily used things and/or disk caching.
