Re: Problems with X in OpenBSD (3.9) -current with LCD WideScreen Monitor
Please give some details about the actual model number of the monitor, the exact model of display card etc. If you are using the radeon driver for instance specifying the radeon option for DDC is a good way of getting the mode information correct. Man radeon discusses the DDCMode parameter. Otherwise it may require that you need a ModeLine parameter in the monitor section. I needed to do this on my laptop to get 1920x1200 widescreen mode.

Under 'Section Screen', add/alter a couple lines: Default Depth 24 and under 'SubSection Display' add: Modes 1280x1024 (correct the Depth and Modes to the values you want, of course). You may be in business. You may not be, if your video card or X driver is incapable of driving your monitor at the desired depth and resolution, or if there is some other quirk in your hardware we can't see.

How to find memory leak in library/OS?
Is there some simple way to find a memory leak in some OS supplied library? I have a (constantly running) application that grows in a week from 5MB to 15MB in size (VSZ and RSS as reported by ps). The application can be compiled with an optional debugging memory allocator that tracks all (de)allocations to check whether any of its malloc()/free() calls leak memory; according to that tool the application behaves fine. Hence I'm wondering whether there is a memory leak in some library or the OS, which also could be triggered by the way my application uses it (see the recent thread about telldir()/seekdir()). My application uses pthreads and the DNS resolver, the latter by contacting it via UDP: sendto(), recvfrom(). Note: the memory leak seems to be unique to OpenBSD (3.8 and earlier), I can't reproduce it on SunOS 5.9 and others. That's why I'm asking for hints where to look for the leak: is there some simple way to show the allocated memory in the debugger or via system calls and to find out which functions made those allocations?

Hence I'm wondering whether there is a memory leak in some library or the OS, which also could be triggered by the way my application uses it (see the recent thread about telldir()/seekdir()). The approach that I used with smbd to find the telldir()/seekdir() leaks wasn't simple, and it did involve some patience and trial and error, but I'm not sure it was particularly complicated either. Basically, I recompiled smbd to link with the dmalloc library which is designed to augment the system malloc()-type calls. The samba devel team thoughtfully includes developer code to support this -- I simply needed to recompile the app and turn it on. Then I ran the program with the test case that caused it to leak memory and watched the dmalloc output as smbd exitted. This confirmed the leak; dmalloc catches leaks even if the underlying leaking malloc() is buried in a system call -- or at least it did in this case. Unfortunately, dmalloc only reported a stack return address to identify the culprit, so I ended up having to trace through the code and narrow the issue using dmalloc mark and reporting calls. If this is your own code, then this should be significantly easier than tracing samba code -- but I had to go through this step to understand what part of samba was leaking memory. At this point, my assumption was that it was something odd that samba was doing for my particular install. Eventually, once I'd narrowed the leaking code in samba, I ended up attaching to the process using gdb and determing where the return address on the stack was pointing. In my case, that was in the middle of telldir(). If you choose to try dmalloc (dmalloc.com), there are some very nice tutorials on their website for using a debugger to help track memory issues. I also used the internal libc malloc() debug options to help confirm the memory leak, though I wasn't as successful at identifying the leak with it. It did provide another avenue to confirm that the app was leaking. There is test code floating around on the telldir() threads in tech@ that might give you a template for using it, though this may require a recompile of libc to turn on the MALLOC_STATS option. It may be simpler to man malloc to see the easiest method for enabling the memory debugging code buried in libc. Maybe someone else on the list can give some insight into the dump results of the malloc() stats to see if there is a way to determine the caller, maybe in conjunction with gbd? So, that's the approach that worked for me. There may be much simpler approaches and/or tools depending on the code you are working on. I'm far from an expert at this ...

The application (it's the sendmail X address resolver) uses a new mutex/condition variable for every request in the test that triggers the leaks. Thanks for your answer! I recently went through a similar exercise looking for leaks in the jvm thread creation and destruction code. The process is simple but tedious. Build a debug version of libc, libpthread and your application. Put a break point on malloc, realloc free. When malloc and realloc are hit, do the finish gdb command and note the returned address on a pad and where it was called from. When free is called cross off the matching address from the list. Whatever is left is the source of your leak. There are things you could do help the process along, like using gdb's 'commands' feature. If you suspect the pthreads library is leaking you could place break points at the malloc / realloc / free calls that your application hits in pthreads (ie break at the calls to malloc in the pthread code, not at malloc itself). -Kurt

The application (it's the sendmail X address resolver) uses a new mutex/condition variable for every request in the test that triggers the leaks. Thanks for your answer! I recently went through a similar exercise looking for leaks in the jvm thread creation and destruction code. The process is simple but tedious. Build a debug version of libc, libpthread and your application. Put a break point on malloc, realloc free. When malloc and realloc are hit, do the finish gdb command and note the returned address on a pad and where it was called from. When free is called cross off the matching address from the list. Whatever is left is the source of your leak. There are things you could do help the process along, like using gdb's 'commands' feature. If you suspect the pthreads library is leaking you could place break points at the malloc / realloc / free calls that your application hits in pthreads (ie break at the calls to malloc in the pthread code, not at malloc itself). -Kurt This tedious book-keeping process is exactly the thing computers are supposed to be good at doing. I've had a special version of malloc that I've used for years which does this and a few other tricks. It's not exactly elegant, because it requires relinking and usually additional hooks in the application to take full advantage of the leak detection, but when all else fails, I find it worth the trouble. I had forgotten it had pthread locking logic - it might even be thread safe: /afs/umich.edu/group/itd/build/mdw/xmalloc/src/ No real documentation, sorry. -Marcus Watts

openssh public auth and permissions
OpenBSD 3.7 GENERIC#0 i386 OpenSSH_4.1, OpenSSL 0.9.7d Doing public authentication for a user with example home directory: /var/www/home/myhomedir if there is no public read permissions for home directory example home is set 0751 rwxrwx--x or even 1711 or 1751 the daemon fails reading the file in ~/.ssh/authorized__keys even if the dir .ssh is chmod 755 and the file has world read permissions. The public authentication fails with the error permission denied to read the above file in /var/log/authlog and ssh requests a password. Can u please tell me why Openssh needs read permissions to home + home dir other than x to read a specified world readable file? Any workaround or an answer to this? -Chris

Re: Sys-Admin vs Network Admin
I think it depends on the size of the environment. Large corporate environments will naturally tend to segment and break up into discrete groups (operating systems groups, networking groups, security groups) In smaller environments, it's more natural that admins would need to know something about everything. $.02 PG -- Original message -- From: Deanna Phillips [EMAIL PROTECTED] Qwerty [EMAIL PROTECTED] writes: Would it be fair to say that a Systems Administrator and a Network Administrator are no longer two seperate entities but have become one and the same.

After sitting down to watch said user, realised she was saving files into a folder already containing 22,000 files. Avoiding that folder solved the problem totally.

OpenBSD 3.8 on HP NC6000
I've recently acquired a NC6000 laptop from HP, which I was going to setup with OpenBSD. My first attempt worked perfectly, had X configured and running as well as a few apps under it. However when I tried to get APM to read the battery status, it simply was not able to do so. I figured the problem had to do with the older BIOS on the laptop, so I download and installed the latest version from the HP web site. The new BIOS now has a battery info page whereas it did not before. This is where things get fun... I tried to boot up my system but OpenBSD crashed almost immediately after the initial boot prompt. Obviously I figured that the BIOS update had something to do with it, but as a test I tried to boot with single user mode - still crashed. Ok, big deal I can just reinstall it... Even when booting off the install CD gives me a crash nearly immediately after startup I don't have any way of capturing the screen, but here are the last few lines: Uhub1 at usb1 Uhub1: Intel UHCI root hub, rev 1.00/1.00, addr 1 Uhub1: 2 ports with 2 removable, self powered Uhci2 at pci0 dev 29 function 2 Intel 82801DB USB rev 0x03: irq 10 Uvm_fault(0xd0gga340, 0x0, 0, 1) - e Fatal page fault in supervisor mode Trap type 6 code 0 eip d02ceebf cs 50 eflags 10202 cr2 4 cpl 40 Panic: trap type 6, code=0, pc=d02ceebf The operating system has halted. Press any key to reboot. The hardware is fine, I've done a test install of Windows XP and Fedora Core 5 on it both of which installed and ran fine... I've been meaning to play with and learn Fedore, so I suppose I could live with it, but frankly I'd rather run OpenBSD... Any ideas as to what this error means and what caused it? Better yet, is there any way to work around it? Thanks, Peter

Network management has very little to do with the day to day maintenance of unix systems. The two can easily be separated. But can you separate unix administration and unix security so easily? The problem I've been seeing is more like this: IT department structures where there are teams for doing nothing managing the web server processes and document roots, teams only for handling identity management and account creation, teams for security, DBA teams that own their special slice of the OS. All teams that never meet or collaborate. I've also worked for a couple of very large organizations that did it the right way - they split teams of sysadmins off according to the projects that they were responsible for, and let them have complete control over them. My suggestion, in the article I linked to previously, was to get rid of this rigid compartmentalization and to pay more attention to systems as a whole. Some single entity, be it a person or a team, needs to have full knowledge and control and ownership of the systems they are responsible for -- and this means security -- or those systems are going to be out of control. To me, the worst part is taking the security responsibility out of the hands of the system administrators and giving it to people who have no responsibility for the systems they are evaluating. This creates an adversarial relationship between the teams, and (this is the part dear to me) it strongly devalues the role of the system administrator. The competent ones will leave, and their replacements will be ever more incompetent, even dangerously so. -- deanna

Re: Sys-Admin vs Network Admin
In the small business I am working for, I am both. I administer the firewall and the BSD box which will replace the current windows file server. Unfortunately, because I am new, he wants a professional. I think it's because I constantly remind him that his security needs improvement: better passwords (they're all 4 numbers with 2 lower-case letters at the end), better organization of data for backing up, etc. But boy, will he be shocked to find out how much a professional will charge him per hour! He only paid me 7.50 USD/hour. Where I live, the statistics for network administrators show that the average pay is 30 USD/hour. Sorry, I got off topic.

Re: Firefox with Java and Flash
do a search of the list archives; I remember somebody asking the same question a few weeks ago and getting flamed for it. The answer was also in there too ;) A Joco Salvatti wrote: Hi all, I have installed in my machine both firefox web browser and java plugin (compiled on my own machine).

rotating apache logs
Hi. What is the best way to rotate apache logs on OpenBSD? Ideally I would like to create a new one at the beginning of each month. I searched my system for logrotate and could not find it. Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Worked well, except Samba panicked regularly - one specific user. After sitting down to watch said user, realised she was saving files into a folder already containing 22,000 files. Avoiding that folder solved the problem totally. I can replicate it on my test boxen here. I believe the issue is related - if not, ignore me, as I am clearly clueless.) Contact me off-list if I can help. Taking the liberty to reply on-list, to draw some attention to this. Yes, the diff is supposed to fix the many files in dir problem in samba. From your post it is not clear if you actually tested the diff (or have used a snapshot, the diff is included in recent snaps). So please try to reproduce this, and report back. While the memroy leak should be gone, there might still be a performance problem with large dirs. I have something up my sleave to solve the potential performance problem as well. -Otto
Re: ADSL with pppoa (over ATM)
My ADSL connection is PPPoA only, which is just PPPoE with ATM. They work at different layers so if you bridge your adsl modem and handle only the ATM part, then openbsd pppoe can do the rest. So this means your ADSL modem will have no public facing IP and reconnecting to it may be tricky once you have set it up. So be careful how you set it up. Can you please post your ppp configuration file? So on the Dlink modem all you just did was to set it on bridge mode. Why it shouldn't work with the 1-port version? I have this (300t) :-( but I upgraded the firmware
