Re: automating 'fsck -y' after a power failure
Joachim Schipper wrote: make a dump of the partition before going to execute potentially data destroying actions? yes, this is sound advice of course. but what are you going to do with the dump if say, fsck is not able to revive the fs? dump it back, run fsck again and answer no at a couple of fsck prompts? how is it going to change anything in the end? Well, if fsck can't revive your partition, you can always try different tools. Something like fsdb may be able to recover part or all of your filesystem even in cases where fsck loses the plot. Also, fsck may fail in the middle due to lack of memory, so moving the dump to a bigger box to make it run through may be a good solution in that case. Or old fsck fails where a -current fsck won't.

My biggest problem is that I cannot get it to create any error output anywhere, not in the xen logs, not in the qemu logs, not in /var/log/messages (on either dom0 or domu), not with sendmail running in the foreground and not in /var/log/maillog (on domu)... It just dies Very frustrating! I was following the stable branch, and I have actually compiled /usr/src -- twice now, it was about 18-20hrs of compiling but went without a hitch.

I appreciate the input. Thanks. Hardware support, indeed, means something like Pacifica. So apparently that isn't the issue. It's rather disappointing that you don't see any log output at all; that makes it rather hard to debug the issue. Still, it's very surprising that sendmail and only sendmail causes this crash; sendmail isn't *that* special. Just to clarify: have you tried running httpd or sshd on the guest system? httpd, in particular, does the same take things from disk and stuff them onto the network as sendmail. (I fail to see why running the server end on the Xen guest instead of host would make a difference, but...) I hope someone with more knowledge weighs in; I must admit that I don't know what could be wrong. Maybe a Xen list could be of more assistance? Joachim
VirtualBox2.2+OpenBSD4.4 (fail)

I believe if you're just using core Perl, you don't need to bring anything else in. I have a big mod_perl app that runs in chroot and accesses PostgreSQL and uses a number of CPAN modules: I have libc, libz, libm, libpq, libcom_err, libssl, libcrypto, libjpeg, libpng, libiconv, and libgd libraries copied in. I also just bring in all my Perl libraries with local NFS mounts: /etc/exports /usr/local/libdata/perl5 -ro 127.0.0.1 /usr/libdata/perl5 -ro 127.0.0.1 /etc/fstab 127.0.0.1:/usr/local/libdata/perl5 /var/www/usr/local/libdata/perl5 nfs ro 0 0 127.0.0.1:/usr/libdata/perl5 /var/www/usr/libdata/perl5 nfs ro 0 0 I suggest you list out what your dependencies are for your app and run ldd(1) on the binaries and libraries you identify.

Let me clarify my answer a bit. There are times, which I experienced recently with Blogsum, that CPAN modules you use() will import other modules within a certain scope (i.e. within a function). In those cases you might have to ktrace httpd to figure out what it's trying to include so that you can add it to your startup.pl. LWP::UserAgent was a major PITA here. I worked around this by not using the module that depended on LWP and rewriting the functionality (Captcha) in my own code and using p5-HTTP-Lite. It was a little more work but it made the application much cleaner and easier to port. This is just meant as an example, YMMV. None of this affected what I had to copy into the chroot (nothing). Obviously, any non-module files that you open() will need to be in the chroot. -- Jason Dixon DixonGroup Consulting http://www.dixongroup.net/

Re: image editor
As far as I'm aware, you wont get lossless jpeg rotation. There does appear to be an orientation tag of some sort in the jpeg header, so rewriting that could cause a jpeg to be displayed with a different orientation. I'm not aware of any software that will do this however. All editors that I've seen will re-encode a jpeg whenever any change is made. Whenever that happens, you'll lose information. (Actually, lossless jpeg encoding is possible but I've never seen a publicly available app or library that impliments it.) paulm On 8/10/2009, at 10:38 AM, Frank Bax wrote: I'm looking for basic image editor: crop, resize, lossless jpg rotation.

Re: image editor
I should have checked first - Google tells me there are quite a few lossless jpeg rotators. A quick ckeck showed qite a few hits for windows apps, 'lossless jpeg open source' turned up lots of hits too, perhaps there's something there ... sorry for the noise. paulm On 8/10/2009, at 10:38 AM, Frank Bax wrote: I'm looking for basic image editor: crop, resize, lossless jpg rotation.

Andres Probably what you want might be something like this in pf.conf match in on $int_if proto tcp from any to ($ext_if) port www rdr-to 127.0.0.1 port 5000 and in inetd.conf: 127.0.0.1:5000 stream tcp nowait nobody /usr/bin/nc nc -w 20 my.internal.gateway.ip.here 80 I believe this was somewhere in the pf faq, not exactly sure, you should start inetd of course. If I'm right you wanna see what's your home hosted httpd doing on the outside interface using your dyndns fqdn from internal network or similar. Actually there's changes in pf so you might want to specify your version. Regards, Dorian
HP Mini 110-1020NR
I purchased one of these to replace an old first-gen Asus eeePC. It was inexpensive and had a very nice keyboard (feels full-sized) and a sharp display. Nice touchpad and buttons too. Works fine with -current. I use USB 802.11 devices when I need to be online. It's extremely fast compared to the old Asus. I was surprised to see how many bios settings had been removed. I could disable crap like the built-in camera in the eeePC, but not this one. There's only like 3 or 4 settings in the entire bios. Here is the dmesg: http://16systems.com/hp/hp-mini-110-1020NR.txt
Dear friend!
Hi, I bought a TV last week from a website:www.hkeles.com. I have received the product. The quality is very good. They also sell phones,motor,psp and so on. Because of the financial crisis, their products are very cheap. by the way, they only sell new and original products .If you need these products, you can have a look . I think you will get many benefits. Greetings!
Re: PF simple rdr help?
Dorian, Thank you. I take it for granted that match is for 4.6 . Thats fine. What is the difference passing it onto netcat, then doing it directly? Aside from this I also need to redirect a range of ports (1500-2000).. and I think the issue would get more difficult if i do it with this method.. --Andres On Wed, Oct 7, 2009 at 6:38 PM, Dorian B|ttner dorian.buett...@gmx.de wrote: Probably what you want might be something like this in pf.conf match in on $int_if proto tcp from any to ($ext_if) port www rdr-to 127.0.0.1 port 5000 and in inetd.conf: 127.0.0.1:5000 stream tcp nowait nobody /usr/bin/nc nc -w 20 my.internal.gateway.ip.here 80 I believe this was somewhere in the pf faq, not exactly sure, you should start inetd of course.
