existing mht file format converter ?
Hi, I'm looking for some mht converter that can put a .mht file into pure html files , and also has abilities to handle unicodes .. So anyone know some cool stuffs that could help ? I know opera could read those shits , besides i found this project: http://www.loganowen.com/mht-rip/ It just received segment fault and dead .. would take some time to debug if no better solution came up ;-) Thanks in advance ! -- Best Regards, Aaron Lewis - PGP: 0xDFE6C29E ( http://keyserver.veridis.com ) Finger Print: 9482 448F C7C3 896C 1DFE 7DD3 2492 A7D0 DFE6 C29E

RAMDISK_CD-based MP kernel hangs when activating secondary CPUs (4.8)
We use a custom i386 RAMDISK_CD kernel: basically we add most options from GENERIC and GENERIC.MP. Upgrading from 4.6 to 4.8, this kernel hangs forever after: root on rd0a swap on rd0b dump on rd0b The problem turns out to be MP; activation of the secondary processors. The custom kernel works fine on a single-core machine, and a recompiled kernel without config lines option MULTIPROCESSOR cpu* at mainbus? also works fine everywhere. -- The problem can be reproduced by simply adding those two MP config lines to the standard RAMDISK_CD kernel config. -- Experiments with adding printf()s on a Dell 1950 (2 CPUs, 8 cores) suggest that the hang happens during: cpu_boot_secondary(cpu_info[2]) pmap_tlb_shootrange() i386_fast_ipi() But treat that as an inconclusive hint: we don't know whether the printf()s are 100% reliable, and VirtualBox (2 CPU, IOAPIC) seems to make it past that point and hang somewhere after init_main() has entered its intentional infinite waiting loop, and another computer (Core 2 Duo) doesn't hang but reboots immediately around that point. -- Are we overlooking an option/driver that's needed for MP on i386? Or is this a kernel regression from 4.6 -- 4.8? +++chefren

You probably have another NameVirtualHost *:80 directive set in another included config file. You can also check http://httpd.apache.org/docs/2.2/vhosts/name-based.html for more information.

softraid - best practice?
Just had a problem with softraid on a 4.6 box. No, I don't ask to solve it, it needed urgent replacement, and so I did. What I would like to ask for, is advice on best practices for softraid under OpenBSD, to prevent similar things from happening again; getting hints on how to set it up better, and mostly: how to recover it better. What happened, was that some slices in a softraid simply went away after some power surge. In detail: sd1 and sd2 were set to RAID, and the ensuing RAID1 (sd3) sliced up into a number of /usr/, /var, /home/, /var/www, /var/mail, swap. After the reboot after a power surge, two of the slices (/var/mail, sd3g and /home, sd3h) were simply unavailable, couldn't be 'mount -a'-ed at reboot, and the system fell back to '/' only being mounted (on sd0). Strangely, though, disklabel sd3 showed the slices, as sd3g, sd3h. But they could not be accessed at all; and were not visible under /dev/. Still, an unexpected bahaviour as far as I am concerned, even more so since sysctl and bioctl showed an 'OK' and 'Online' softraid. I tried a few things, like fsck_ffs on these two disappeared slices, as well as the 'good' ones. The good ones were good, also with fsck_ffs -f. But the two gone missing were just not available (as devices). Then I made, I guess, a big mistake, and instead of ripping out one of the drives, I bioctl -d -ed sd3; leaving 2 drives with RAID file system on them. Over. Now, please, any suggestions on how to do better next time something like this happens? Thanks in advance, Uwe

Re: 1gbit LAN/NIC performance, queue speed bug?
this is very illuminating. it says that initially, tcp send/receive window is your bottleneck. when you increase them to 131072, the cpu becomes your bottleneck and remains that way no matter what else you tweak (idle drops to 0.0% and stays there). the next question is, of course, why is your cpu spending all its time in system and interrupt? is it doing unnecessary work, or is the work necessary and your cpu just isn't fast enough? I don't have ready answers to these questions. -ken Hello, I see, that while I am testing network speed by iperf, 100% CPU is being used, but is that normal for default install of OpenBSD 4.8 with default pf.conf?? I have second computer exactly like that one (IBM ThinkCentre A51P), on which i am running this tests but with P4 3Ghz CPU 2mb cache (not celeron 2.8) and the same is happening (100% CPU). LAN interface is Intel PRO/1000 PT Desktop Adapter (PCIe, model: EXPI9300PTBLK) and this is the only pcie adapter in computer (maybe broadcom integrated nic is also pcie but is not used) So the conclusion might be: - there is problem with my Intel NIC model/cheapset - there is problem with em driver - there is problem with my hardware (I need serwer motherboard with pcie and pci 64bit 66mhz) - I need faster CPU than P4 3GHz ?? or - there is a problem with iperf :) How about measuring with something else? Did you try tcpbench? Or something even simpler, like scp-ing from /dev/null to /dev/null? With pf and queues enabled you can monitor the B/S rate.

The `bioctl -d` command is non-destructive for softraid - it will detach the softraid volume and you should be able to reconstruct it again with `bioctl -c`. Now, please, any suggestions on how to do better next time something like this happens? Without further information it is hard to tell what has actually occurred - if you have indeed lost device nodes then it is likely that fsck reported that it made corrections to sd0a (possibly even after it asked you to confirm those changes). Regardless of any hardware or software RAID you will still potentially face filesystem level problems with sudden power outages - the best solution is probably to get yourself a good UPS. -- Stop assuming that systems are secure unless demonstrated insecure; start assuming that systems are insecure unless designed securely. - Bruce Schneier

OpenBSD EOF characer?

A Ctrl-D on a new line should (and does) do the job.

Gnome running slow
Hi, I experience a dsktop running quite slow, I have seen it running well sometimes. Gnome is simply slow and I have no idea why, after login, it is not always that slow, sometimes is runs well. Apparently, with top I see Xorg consuming many resources. I have no idea how to solve this. Do you have any experience with this ? Thanks
Re: An OpenBSD smartphone
You're looking at this from a programmer's perspective and not from a business one. let's look at the basic Unix-like/descended systems: All were developed because each founder- or founders- saw a niche, necessity, or challenge. Nokia, Google, and Apple are business entities whose purpose is to create revenue by selling products or services. You're going to wait until 15,000 or more people demand/ask for pf on a smart phone? Neither the mainframe nor the desktop nor the cell phone were created because the public wanted them. Look at advertising and how it works. 1) Create a need for a product by using two or more of the appeals. Culture, society, ethnicity, family, etc. 2) PR is important. If you're a programmer and you want the product out: 1) I'm not sure how ARM is but I do know that the company designs chips. 2) You'll have to build the system and take gtk and qt sources to build on it. What won't sell to the public is the conversations on the mailing lists or between programmers. What will sell are key points such as: 1) It is two to four times faster than other smartphones and uses half of the memory. People like it when extra shit runs smooth on their tablets and phones. 2) It can be used as a router for other devices and still work as a phone. What? I can make a call, browse the web, and still hook up my netbook? 3) The system is stable. Your personal information remains as such. 4) And for the hackers... You can do what you want with it. The programmers are for support, development, and design. Yes, I am a business major. I have experience in selling futures. I am certified in management. You can see this as a business opportunity and a challenge or you can continue as before. Those of you who do have a working understanding of the basic business model will have no trouble following this post.

killing states in pf
Hello, Using pf on -current doing nat and I want to kill all of the states related to a specific internal IP address but I'm having an issue doing so. I have as an example (79.39.147.11 is outside IP from ISP): # pfctl -ss |grep '1\.100' all tcp 79.39.147.11:53190 (192.168.1.100:58853) - 67.2.45.22:12510 ESTABLISHED:ESTABLISHED all tcp 79.39.147.11:62777 (192.168.1.100:40664) - 26.217.28.131:25794 ESTABLISHED:ESTABLISHED all tcp 79.39.147.11:58425 (192.168.1.100:39548) - 33.127.87.221:24324 ESTABLISHED:ESTABLISHED None of the wildcard scenarios associated with internal address will kill the above states: pfctl -k 192.168.1.100 -k 0.0.0.0/0 pfctl -k 0.0.0.0/0 -k 192.168.1.100 I can use: pfctl -k 79.39.147.11 -k 67.2.45.22 or: pfctl -k 0.0.0.0/0 -k 67.2.45.22 each connected outside IP address must be specifically specified. Not so bad if it was only 3 addresses but that's not the case. I'm not even quite sure what those states mean - why is the internal address in (). If memory serves (be kind it doesn't always) the old pf had states like: all tcp 192.168.1.100:58853 - 67.2.45.22:12510 all tcp 67.2.45.22:12510 - 192.168.1.100 where the internal address didn't show up in parens, and it was easy to kill all of the states related to a specific internal IP address. It seems that is now impossible (at least I haven't figured it out yet). Thanks for any assistance, Chris

Book of PF 2nd Ed. Kindle edition validity
