I can't comment on the ResierFS or AcceleRAID support but I can comment on the stability of the 2.4.2 kernel. We have been running 2.4.2 on our Web servers which also do DNS, mail, mysql and FTP for 50 days now, without a problem. The 2.4.x kernel is definitely faster then 2.2.x (no I didn't benchmark it :-) and it is perfectly stable. We have also run 2.4.3 on a test box and have subject that to some ugly situations without harm. However, be aware of the security hole (security cavern!) in iptables, so don't use the firewalling features. The problem is supposed to be fixed in 2.4.5. Also be sure to read the kernel source as you must upgrade modutils and few other packages from woody to get 2.4.x to work. Pete -- http://www.elbnet.com ELB Internet Service, Inc.

Re: system mirror

We use rsync ( http://rsync.samba.org ) to keep our backup servers in
sync with the front line ones. Some reasons we chose rsync was:
- Transfers only the changed portion of files so it significantly
reduces network traffic
- Allows great flexibility in what files to transfer or ignore
- Can use ssh as the transfer agent so no snooping on the transfer
- Supported on multiple platforms including NT {shiver}

That would depend on how much changes from mirror to mirror and what
you mirror (i.e. mail changes a lot but the files are small).
To givbe you an idea we mirror a server (user accounts with
htdocs,mail,MySQl, etc) last night with about 30GB of "stuff" over a
local network using full-duplex 100Mbs in just over 4 minutes. Only
about 5MB of that 30GB was actually transfered. the rest hadn't changed.

I'd be glad to send you the pin outs if you go with this particular unit otherwise genpowerd come with a tool to help you figure it out on your own. The Back-UPS is a "dumb" ups. It only tells when power fails/restores and allows you to shut down the ups. A smart ups will tell you bunches of info like battery charge state, current draw, current P/E of Cisco...:-) There are also the packages apcupsd and apcd which handles a number of APC ups.

Re: Auto 10/100Mb card fallback from 100 to 10 on 100Mb network
> Please... ANY suggestions and help would be greatly appreciated. I'm sure you've already tried these but: Are you sure it is not a noisy cable problem? - Try a different cable - Try a crossover cable directly from card to card to eliminate the possibility of a card to switch problem. - You are running a *switch* and not a *hub* right? (I had to ask!) - Did you look at the 8139too.txt in the 2.4.x Documentation? I'm running SMC cards with the 8139 chip in 100Mbs mode on 2.4.2, 2.4.3 and 2.2.18 without trouble. I compiled the driver into the kernel instead of as a module but that shouldn't matter. I'm sure that this was of no help! :-) -- http://www.elbnet.com ELB Internet Service, Inc.

FTP creates two connections: an outbound connection and a return connection. The outbound conection is easy: from the clients unprivledged ports to the server port 21 and back. The return connection is a problem. You have to allow *anyone* to connect to your port 20. The reason that you do not get a login prompt is that the firewall is rejecting the inbound connection. Often you can get around this problem by using passive mode FTP (which is probably why they can connect to the M$ box) which connects to one of your unprivledged ports instead of 20. Another way around the problem if your client doesn't want to mess with their firewall is to offer HTTP based FTP. Pete -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
