Re: NetBSD disk backup over network

The idea is bloody clever but sounds like a bit of a hack right now. You can already do this with GEOM. On your server node, create a sparse file using dd, that is the same size or bigger than the partition you would like to back up. Then set it up with ggated. Now, on your machine with the partition that needs mirroring (backing up), use ggatec to connect to the backup node's shared sparse file you previously created. Then, use gmirror to mirror your partition to the now local ggatec'ed device.

userland access to mountpoint's struct mount
Sorry if this is a very basic question, but I'm trying to extend the struct mount (sys/sys/mount.h) to contain a lot of statistics, and then use a userland tool to read those statistics on a per mounted file system basis. I can't seem to figure out exactly how to do this, and even if this really is what I want. Life might be easier if I wedge it into the struct statfs per file system - but is that ok to do?

sshd (or global) max-connections-per-user setting under FreeBSD ?
I am running a stock FreeBSD 6.0-RELEASE system, with the built-in ssh/sshd. I am interested in limiting the number of ssh connections any particular user can make to the system ... for instance, if limited to 3, they could login interactively, commence an rsync over ssh, and commence an scp file transfer, but could not initiate a fourth ssh transaction of any sort. I don't see an obvious way to do this, and further, I am not particularly interested in running sshd out of inetd, which _might_ help me accomplish this... I am wondering the following: - is there a general max connections per user mechanism in FreeBSD that I could use ? I only allow ssh connections, so I don't need it to be sshd specific - I would be happy with a global max conn mechanism... - (if there isn't a global maxconn) is there an elegant way to limit max connection for sshd ? I feel like I could do this with pam.conf, based on the documentation, but I don't see how, and further, there is no pam.conf in a default install ... so perhaps I add it to /etc/pam.d/sshd (or perhaps /etc/pam.d/system for global ?) I am sorry to ramble - all comments and suggestions are greatly appreciated. thanks. __ Do You Yahoo!? Tired of spam? Yahoo!

You can write your userland code to use whatever files or devices you want. Are you talking about the scs_target.c code in /usr/share/examples? That's just a skeletal example that you can use as a starting point for your own work. No, it's not just a skeletal example. You can point it at a raw device as the backing store file and it will work as a block device (i.e. RBC command set). It has been tested as working at least moderately fast over SCSI, FC, and firewire. I'm finally getting around to playing with this, and I'm having some problems. First, I can't seem to make one isp card in target mode and the other an initiator. I've messed with adding the following to loader.conf: hint.isp.0.role=initiator hint.isp.1.role=target that still doesn't show my currently connected fiber channel devices on the initiator side. I've tried a few different kernel options, currently I have: options ISP_TARGET_MODE=1 device targ I've also tried just: options ISP_TARGET_MODE and that doesn't seem to allow me to select one either. Anyhow, I've compiled scsi_target (from /usr/share/examples/scsi_target), and tried to run it using a 20gb file as the target, and still I can't seem to get it working. Is there a doc somewhere I need to read? Also - as a side note, the Makefile for scsi_target seems like it's missing a path variable in order to do a make install, but that's not a real issue.

We have a serial console set up, I broke to the debugger and got the following. Since the hang is in the disk I/O system, a dump is not possible. The many versions of inetd are likely due to users attempting to POP their email. Any suggestions or tips on how to track this down and get it resolved would be appreciated.
