Re: AAC driver. No kernel error messages for failed raid5?

I was expecting kernel messages about it, but got nothing. This is missing functionality in the aac(4) driver. For now about the best you can do is regularly poll the status using Adaptec's CLI tool arcconf. -ED The tool you need to look into is: sysutils/aaccli . I think arctool is only for arcmsr-devices. unfortunately aaccli doesn't provide the possibility to use it with parameters, so you probably need to use it with an expect-script. On the adaptec 2410SA I activated the alarm feature in the controller bios, which helps me, because its a home server but this will not help you if your server is sitting somewhere else. Because of this limitation (and a few other things with the controller) I'm certainly looking for an other solution. In my case a ZFS-based software RAID will suffice, but this might not be desirable for you.

Re: ZFS + gmirror: how?
On 27/04/2008 20:44 Guus Houtzager wrote: Hi, I'm rather new to FreeBSD and I'm having trouble with ZFS and gmirror. I've used this guide to install FreeBSD 7 on ZFS: http://www.ish.com.au/solutions/articles/freebsdzfs This goes flawless, however, the /bootdir is still just /dev/ad01sa (in my case), so if that disk breaks, I still can't boot from ad1. So I thought I could just make a gmirror containing /dev/ad0s1a and ad1s1a and use that for /bootdir. This however does not work. What I did is: - gmirror load - gmirror label -v -b round-robin gm0 /dev/ad1s1a - newfs /dev/mirror/gm0 - mount /dev/mirror/gm0 /mnt/tmp - dump -L -0 -f- /bootdir | (cd /mnt/tmp restore -r -v -f-) - edit /etc/fstab and /mnt/root/etc/fstab: change all references to ad0s1a by /dev/mirror/gm0 - echo 'geom_mirror_load=YES' /boot/loader.conf - echo 'geom_mirror_load=YES' /mnt/tmp/boot/loader.conf - reboot However: I can see the bootprocess starting first ZFS followed by a message saying it's waiting for GEOM gmirror to start, which it does after a little while and then I get a prompt where I can manually tell the system where the root filesystem is. And if I tell it zfs:system/root it does not work (my zpool is named system). Anyone know what I'm doing wrong and what's the best way to do this? Thanks in advance! PS: please CC me in any reply, as I'm not subscribed to this list. Thanks! Regards, I'm not sure if this is the cause, but it looks like /boot/zfs/zpool.cache might not be up to date or missing. Once I had the same issue. You should boot up somehow (you can even use the 7.0 install CD). Make sure you have the directory /boot/zfs and do a zpool import. After this you should have a valid zpool.cache file which you need to copy to your mirror device. PLMK if this works for you as this is also my desired setup. I only need to make the gmirror step tough ;-) br, Robert ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: SCSI network

I'm more concerned about SCSI bus addressing being a problem. Perhaps the statement above means that each card can have a distinct ID on the bus. My experience with SCSI is pretty much limited to systems where the host computer is hardwired as device 0. If these cards are like that, they'll likely be pretty confused about who's who. Usually you should be able to change the Host-ID (which is 7 per default), but the real issue with SCSI is, that there is always an initiator which connects to a target, although this can change (as you state) its not as easy as opening an other network port. Think of it as usb, you cannot hook 2 PC's together without some special device in between (ok SCSI is a bit more flexible tough). The only things that popped up on google were pretty much outdated (around 1998), so this will not really help you. It looks like the guys played with this to overcome the fast- ethernet limit. If you really need something fast, grab some used FC switches (Brocade) with GBIC's equipped and some cheap HBA's (e.g. emulex or qlogic). In this scenario you can run FC-IP which works well. There you can choose between 1/2/4G per sec depending on the money you want to spend (4G is way off limits!) Personally I think this is a little overkill, although nice to play with. :-) If you need a cheap solution why don't you equip you PC's with FireWire cards? But ask somebody about the limitations there (IMHO you can make some sort of bus connection, but worst case it would be one-to-one connections). br, Robert ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Hi,
Is there a quick/easy (cookbook?) way to do port

I'm using ipfw for some other things so it has to
work and play well with that.
Thanks, Tuc
In case you want to try transparent proxying you need to look into
firewalling.
I can only tell you how this would work with OpebBSD's PF since I use it
myself and quite like it. :-)
Have a look at pf.conf(5), but it should work like this (in /etc/
pf.conf):
+
int_if = em0
rdr on $int_if proto tcp from $int_if:network port { 80 } -
192.168.0.1 port 87
+
In this example you need to specify your network interface as int_if
(in my case it is em0)
If this doesn't suit your situation, you probably need to give us more
information: The
kind of network setup you use (eg internal - firewall - external)
and what needs to connect
to and from where. do you have a firewall solution in place (PF,
ipfilter, ipfw)? And what do
you need to achieve?
br good luck,

Re: Understanding Flags, Refs, Use, Expire in Routing Table
Hi Daniel, you find mostl of you questions answered in man netstat (the relevant passage is posted below) The missing part is the expiry, which IMHO are the seconds, the ARP entry is valid (after this time a new arp request would be issued) I hope this is the information you needed. br, Robert +++ The routing table display indicates the available routes and their sta- tus. Each route consists of a destination host or network, and a gateway to use in forwarding packets. The flags field shows a collection of information about the route stored as binary choices. The individual flags are discussed in more detail in the route(8) and route(4) manual pages. The mapping between letters and flags is: 1RTF_PROTO1 Protocol specific routing flag #1 2RTF_PROTO2 Protocol specific routing flag #2 3RTF_PROTO3 Protocol specific routing flag #3 BRTF_BLACKHOLEJust discard pkts (during updates) bRTF_BROADCASTThe route represents a broadcast address CRTF_CLONING Generate new routes on use cRTF_PRCLONINGProtocol-specified generate new routes on use DRTF_DYNAMIC Created dynamically (by redirect) GRTF_GATEWAY Destination requires forwarding by intermediary HRTF_HOST Host entry (net otherwise) LRTF_LLINFO Valid protocol to link address translation MRTF_MODIFIED Modified dynamically (by redirect) RRTF_REJECT Host or net unreachable SRTF_STATIC Manually added URTF_UP Route usable WRTF_WASCLONEDRoute was generated as a result of cloning XRTF_XRESOLVE External daemon translates proto to link address Direct routes are created for each interface attached to the local host; the gateway field for such entries shows the address of the outgoing interface. The refcnt field gives the current number of active uses of the route. Connection oriented protocols normally hold on to a single route for the duration of a connection while connectionless protocols obtain a route while sending to the same destination. The use field pro- vides a count of the number of packets sent using that route.

Re: A general purpose LDAP solution?
You could follow one of the general purpose samba-ldap documentations out there, because AFAIK samba is the most influencing service to depend on ldap. I cannot recall what I used but you can have a look at: http://gentoo-wiki.com/HOWTO_LDAP_SAMBA_PDC_Basic_Setup http://www.samba-ldap.de/samba-3-pdc-mit-ldap.html the first one covers gentoo, the latter is written in german... but you get the point. One suggestion from my side is to use a OU base instead of DC based if you are using multiple (internet-)domains. To specify who can use what service, you can use ldap query-filters (eg. for apache create a group webusers and so on) At tme moment I use openldap for web, mail (Postfix cyrus-imap), samba and a per user address-book. Kerberos (heimdal) and radius is also possible, but I do not use it at the moment. If you require it, I can provide you with more information or even relevant parts of the config-files. br, Robert Jesacher On 25/03/2008 14:38 Outback Dingo wrote: As would I also like to On Tue, Mar 25, 2008 at 8:11 PM, Trey Sizemore [EMAIL PROTECTED] wrote: On Mon Mar 24, 2008 04:58PM, Tim Judd wrote: Jon Theil Nielsen wrote: I asked this on freebsd-net@ but got no replies.

I liked the virtual part of everything, so I stopped after getting email working. I didn't want to open up my system to all sorts of unix/samba logins that might exploit or give me problems. The email system I documented isn't ready for publishing. I'm having some select friends review it and proofread it first.
