sendmail - kmail - lockfile ?
by John Walsh
Hi,
I have a question, see below, which someone was helping me with,
but their answer does not really cover what I want to know, because
they say they don't know how kmail works.
Anyone have a real/better/full answer to my question ?
Which is, in short :- what locking method should I use for Kmail to read a
local mbox file that sendmail is delivering to ?
Extract from below:

Yes, Kmail has an option to read 'local mbox' accounts - but you have to
select the locking method for it - which one should I be using ?
Thanks,
John.

wheel on mouse doesn't do anything after upgrade
by Dr. Michael J. Chudobiak
Hi all,
After upgrading from FC1 to FC2, the wheel on my Logitech MX700 cordless
optical mouse stopped working. In other words, the scrolling feature
doesn't work. The rest of the mouse works. Any suggestions on how can I
fix that?
My modprobe.conf file has:
alias usb-controller uhci-hcd
alias usb-controller1 ehci-hcd
(Do I need "ohci-hcd" too? Or instead?)
I had to completely re-write the sound section of my modprobe.conf file
to make the Intel 8x0 sound chip work...

FC2 doesn't recognize ext3 /home partition
by ali baba
Hi,
I tried updating to FC2. My /home directory was
located on my second harddisk (samsung spinpoint wih
121GB) previously. So I wanted to leave my /home as
is, i.e. not formatting it and not having to backup
everything. But FC2 recognizes my ext3 /home partition
as a win32 partition... what a shame :-)
Help!?!!
Thanks!

Linksys WPC54G and FC2
by Robert Spangler
Hello,
I can seem for the life of me to get the 2 to work together.
I downloaded ndiswrapper and installed it according to the install
instructions.
'make install'
make -C driver install
make[1]: Entering directory `/temp/ndiswrapper-0.8-rc1/driver'
make -C /lib/modules/2.6.5-1.358/build
SUBDIRS=/temp/ndiswrapper-0.8-rc1/driver DRV_VERSION=0
.8-rc1 modules
make[2]: Entering directory `/lib/modules/2.6.5-1.358/build'
Building modules, stage 2.
MODPOST
make[2]: Leaving directory `/lib/modules/2.6.5-1.358/build'
mkdir -p /lib/modules/2.6.5-1.358/misc
install -m 0644 ndiswrapper.ko /lib/modules/2.6.5-1.358/misc
/sbin/depmod -a
make[1]: Leaving directory `/temp/ndiswrapper-0.8-rc1/driver'
make -C utils install
make[1]: Entering directory `/temp/ndiswrapper-0.8-rc1/utils'
install -m 755 loadndisdriver /sbin
install -m 755 ndiswrapper /usr/sbin
install -m 755 wlan_radio_averatec_5110hx /usr/sbin
make[1]: Leaving directory `/temp/ndiswrapper-0.8-rc1/utils'
Then I install the drivers from the CD that came with the card.
'ndiswrapper -i /mnt/cdrom/lsbcmnds.inf''
Then I look at the list.
'ndiswrapper -l'
Installed ndisdrivers:
lsbcmnds present
All looks good to this point. I then run modprobe as instructed
'modprobe ndiswrapper'
It states that there should be no errors which there wasn't. Next I try to
locate the wireless interface.
'iwconfig'
lo no wireless extensions.
sit0 no wireless extensions.
eth0 no wireless extensions.
No wireless. The card is in it's port but nothing. Could some please tell me
what I missed? I would be grateful for any help on this matter.

Re: How to preserve users in new install?

maybe they have a policy of not overwriting a working system - but they
want to get a seperate system (on a second disk) working first. Then if
the new system had problems, they can just go straight back to the old
system - because they did not 'upgrade' it.
This is what I do, having my disks in caddies...
Doing an 'upgrade' would be simpler I'm sure, until something goes wrong.
Then I'm thinking: well, was the new version installed correctly or is there
really a problem in the new version... ?
No, I'd rather start from scratch and know whats on my disks... and have a
spare disk with a known working system on it...
John.
ps. my answer to the original question - I do exactly what you
suggest and it works for me. But I do keep a lot more files:
./etc
./etc/sysconfig
./etc/sysconfig/network-scripts
./etc/sysconfig/network-scripts/ifcfg-eth0
./etc/sysconfig/network-scripts/ifcfg-eth1
./etc/sysconfig/network
./etc/sysconfig/dhcpd
./etc/sysconfig/rhn
./etc/sysconfig/rhn/up2date
./etc/sysconfig/rhn/sources
./etc/sysconfig/rhn/up2date-keyring.gpg
./etc/sysconfig/rhn/systemid
./etc/sysconfig/i18n
./etc/rc.d
./etc/rc.d/init.d
./etc/rc.d/init.d/network
./etc/rc.d/init.d/iptables
./etc/rc.d/init.d/milter-spamc
./etc/rc.d/rc.local
./etc/rc.d/rc.sysinit
./etc/X11
./etc/X11/XF86Config
./etc/httpd
./etc/httpd/conf
./etc/httpd/conf/httpd.conf
./etc/mail
./etc/mail/local-host-names
./etc/mail/sendmail.mc
./etc/mail/virtusertable
./etc/mail/access
./etc/hosts
./etc/hosts.allow
./etc/hosts.deny
./etc/resolv.conf
./etc/dhcpd.conf
./etc/group
./etc/passwd
./etc/shadow
./etc/motd
./etc/crontab
./etc/inittab
./etc/sysctl.conf
./etc/modules.conf
./etc/aliases
./etc/ssh/sshd_config
./etc/profile
./etc/cron.daily
./etc/logrotate.d
./etc/yum.conf
./etc/smartd.conf
./usr/lib/powerchute/powerchute.ini
NB. ignore leading '.'
basically, I keep ALL the config files I ever change.
and then I can use them directly or as a reference in the new system...
and I keep all this (and /home) on a second disk, so I only need to
re-install
over the first 'system' disk.

How odd. I am looking at Fedora Core 2 through a Zonet KVM3004 at this
very moment, on the screen next to this one.
[NumLock][NumLock]2 Now I am looking at Redhat 7.3 .
[NumLock][NumLock]3 Now I am looking at Solaris 9 on an UltraSparc 2.
(connected through an interface converter).
[NumLock][NumLock]4 Now I am looking at Windoze NT (erase, erase!)
[NumLock][NumLock]1 Back to Fedora Core 2.
I suppose what they mean by "not support" is, "if you try to balance
a stack of Fedora Core 2 Install CDs on top of the curved Zonet case,
they will slide off". Alternately, they may be referring to the
difficulty of uploading a distro to run on the KVM hardware itself.
Or possibly, just possibly, Zonet has a blithering idiot answering
email who cannot read the KVM3004 box, which states quite clearly
that it works with Linux (and how could it not?). For a picture of
the back of the box, see http://www.keithl.com/kvm3004.jpg .
Dwaine, thank you for contacting Zonet for us. I'm glad that there
are people on this list who have the gumption to do research. Now,
however, you must contact Zonet management and let them know that
their competitors are hacking their email, or their employee roster.
---
All kidding aside, the Zonet KVM3004 works just fine. It comes with
cables (though you may want some longer ones), the resolution is good,
and it is inexpensive. I can boot computer A while using computer B,
and A will get the necessary info to set up keyboard, display, and
PS/2 mouse. My only (minor) complaint is form factor; it would be
nice to have all those cables running out the back of the case rather
than off the sides, but that would be more expensive to build.
