Now I have to merge all these mail folders. I copy everything onto my laptop so that when it becomes the active mail machine, it's also the master keeper of all mail files. I manually set which system is in charge of mail, and its files clobber the ones on the other system when I sync them. When I just go out for a day or two and leave my home machine on and pulling my mail down, my laptop isn't the master of my mail, so I Bcc myself (with fully-qualified, non-local address) to archive outgoing mail I write while offline. There are two drawbacks to my setup: 1) When I go out for the day, I may make changes to my mail folders and spools. When I return, those changes are lost. I do this because it's critical that I not lose new mail in the spools at home, and I'm happy being overly cautious in this case. 2) If I pull down mail on my laptop and resync with my desktop machine without setting my laptop to be the master mail machine, I will lose mail. Similarly, if after I return and sync I forget to set my desktop machine to be the mail master, I'll lose mail when I sync with the laptop. I haven't had any problems yet because I've been careful enough and don't fetch mail from my laptop often. The vulnerability could be fixed with some locks and script changes, but as I'm ditching my desktop machine in a couple weeks, I won't have to worry about it anymore.
using nfs on install
I'm trying to reinstall debian on my laptop since I was having trouble getting potatoe to install. Anyway, I was able to find a 2.1 cd and I picked up a 3com Etherlink III network/33.6 pcmcia card. The question is, how can I bet the install program to bring up the network so I can nfs install the base system? Before I started trying to reinstall, the network was up and running (and I had not done anything since replacing my 14.4 modem with the new card). Ideas on what to do? Thanks, Chris

Since I use Netscape Messenger as my e-mail client, I handle this case by just using Compose, then saving unsent messages in the Drafts folder. I can later command Netscape to send the queued messages. Sendmail is really not good to use on laptops. It very strongly assumes that you are always connected and DNS is always available; it simply wasn't designed to work in an environment where DNS is not available, so I wouldn't recommend trying to use it in one. --Greg

You need to eject the card before you suspend. That is true even on Windoze. What I do is eject the card, then suspend, and when I reactivate, I reinsert the card and then run my DHCP restart script which reconfigures the Ethernet interface. This does, however, require that a DHCP server be available on the networks you connect to. --Greg
Re: using nfs on install
After you install the driver disk (installing the nfs module of course), go to the "Configure PCMCIA" option, then do the network config, telling it you will use a pcmcia network device. Then when you install the base system, tell it you will use nfs. I just did it today. -Jim Jensen [EMAIL PROTECTED]

On my laptop, I've installed the nfs module I've setup the network at 192.168.1.10 and told it to use pcmcia. On my other box I've setup the /etc/exports file with /mnt/cdrom 192.168.1.10(rw).. When I tell the install to mount 192.168.1.3:/mnt/cdrom it gives me "Error mounting NFS filesystem 192.168.1.3/mnt/cdrom , please try again". What am I doing wrong? When I load up a second console on my laptop and run ifconfig, it justs lists lo. Why is the pcmcia network not being listed??? thanks, chris
