Re: after youtube .swf, black xterm text => transparent
23.11.2012 06:22, Gary Aitken: Do you have a nvidia card ? If yes right click on the youtube image and disable hardware acceleration, it will probably solve it (solved for me) I'm seeing this too. nvidia-driver is installed. I'm using E17 without opengl. While this should work for flash plugin I was always hit by another bug - < I can't use mouse on flash settings dialog unless flash is maximized. Hmmm. Seems to work for me whether normal sized, large sized, or full screen. So the menu comes up on the right click, and you can select "Settings..." and the settings dialog comes up, but you cannot change any of the settings? I can navigate partially by keyboard. But you can close the dialog using the "close" button using the mouse? Mouse doesn't work at all. And you can switch tabs in the settings dialog using the mouse?

PF and tables for disabling network

Then, if you want to kill the active connections from people in the table, you might want to "script" a bit, like: for i in `pfctl -t closed -T show` do pfctl -kK $i done Would that do the trick for you ? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
newfs -m for large filesystem
Hello, are the remarks given for the -m option in tunefs(8) and newfs(8) still the same for very large filesystems, or the free-space margin might be safely reduced in these cases? For instance, when I have a 12TB filesystem then the default 8% margin gets close to the value of 1TB, which seems like a waste of capacity.

You can use pkg_cutleaves with pkgng in this sort of situation. The autoremove flags don't get set by pkg2ng unfortunately, as it can't tell what you installed explicitly by name and what was pulled in as a dependency. As you keep using pkgng, the autoremove flags will get set to more sane values and that feature will become more useful.

I ended up booting from rescue media, removing one drive and stopping the gmirror, creating a new gmirror on the removed drive to place the UFS partition first, and performing a dump/restore to transfer the system. Then I was able to boot from the new gmitrror and add the second drive to it. One of the complications was getting old metadata off of the drive. After trying a couple of 'dd' invocations: # overwriting the first sector dd if=/dev/zero of=/dev/ada0 bs=512 count=1 # also tried overwriting the last sector diskinfo ada0 | cut -f4 3907029168 (subtract 34, per WB) (I actually just subtracted the trailing 68) dd if=/dev/zero of=/dev/ada0 seek=3907029100 This would still seem to not delete all of the metadata, since after issuing: gmirror label -b split gm0 /dev/ada0 gmirror load # repartition new mirror gpart create -s MBR mirror/gm0 # ignore "mirror/gm0s1 added, but partition is not aligned on 4096 bytes" after add gpart add -t freebsd -a 4k mirror/gm0 # create the bsdlabel partitions in slice 1 (s1) gpart create -s BSD mirror/gm0s1 I would see that the old gm0s1a and gm0s1b had reappeared, even though I had not yet issued the 'add -t freebsd-ufs'. I'm not sure if they came back with the 'add -t freebsd' or the 'create -s BSD'. The only thing that seemed to fix it was: gpart destroy -F /dev/ada0 I also tried at one point: gpart destroy -F ada0 gpart create -s gpt ada0 gpart destroy -F ada0 After that I could create the new partitions within the slice, with freebsd-ufs first: # size of ufs partition must be calculated, from 'diskinfo -v /dev/ada0': 2000398934016 # media size in bytes (1.8T) ; 1024*1024*1024 1073741824 ; 2000398934016/1073741824 1863.01668548583984375 # subtract 8G from 1863 = 1855G gpart add -t freebsd-ufs -a 4k -s 1855G mirror/gm0s1 gpart add -t freebsd-swap -a 4k mirror/gm0s1 Everything looks good with 4K alignment, and freebsd-ufs first: gpart show =>63 3907029104 mirror/gm0 MBR (1.8T) 63 63 - free - (31k) 126 3907028979 1 freebsd [active] (1.8T) 3907029105 62 - free - (31k) => 0 3907028979 mirror/gm0s1 BSD (1.8T) 0 2- free - (1.0k) 2 3890216960 1 freebsd-ufs (1.8T) 389021696216812016 2 freebsd-swap (8.0G) 3907028978 1- free - (512B) After newfs, I was able to dump/restore to transfer the installed system from ada1 to gm0 (which is 9.1-RC3 now). The thing I wonder about now: Should newfs include -S 4096? I used: newfs -U /dev/mirror/gm0s1a Will this lead to 512 byte sector access to the disk through the file system? Will this impact performance or longevity of the mirror?

Odd X11 over SSH issue
I am seeing very poor response time running the VitrualBox GUI via X11
tunneled over SSH via the Internet. The issue _appears_ to be limited
to the VBox GUI as Firefox is reasonable. I am well aware of the
latency issues tunneling X11 over SSH across the Internet, but that is
what we are stuck with for the moment. The server is running FreeBSD 9
and is patched as of about 4 weeks ago.
Observations:
1. When I first SSH into the box I see a long delay after the SSH
tunnel is setup before being prompted for a password, and I do not
know if this delay is related to the VBox issue. Details below.
2. When I fire up VirtualBox it takes _minutes_ before the window
opens and each action (drawing contents, mouse clicks) takes
additional _minutes_. Looking at the VirtualBox process with truss I
see many, many errors of the form:
read(7,0x80193a02c,4096) ERR#35 'Resource temporarily
unavailable'
where fd 7 is a socket. I would chock it up to network slowness, but I
do not see the same behavior with Firefox, xload, or xclock. An xterm
is even pretty snappy. Timing firefox, it takes under 10 seconds to
draw the window and fill it. It takes about 2 to 3 seconds to draw the
menu after clicking on the menu widget. With VirtualBox is takes
_minutes_ for every action, so it is clearly a call that VirtualBox is
making, but I can't figure it out from the truss output. The
VirtualBox GUI works fine when run on the console or on the local
network (not via SSH). I have a local system that I think is
configured the same way (but much slower hardware) and the VirtualBox
GUI is reasonable via SSH about 10-20 seconds to open the window and
5-10 second response time to mouse clicks). It is only when it is
tunneled over SSH via the Internet that the problem appears.
Details below.
Any suggestions where to look ? Or am I barking up the wrong tree ?

No, in general you can't assume that you'll be able to browse the repo using a web browser or similar. Even if you could, all you'ld see is a lot of pkg tarballs which would tell you the package names and versions and how much data you'll need to download and not a lot else. Use the repo catalogue. It can tell you almost anything you might want to know about the available packages in the repo. Cheers, Matthew [*] Note: the default URL uses an SRV record in the DNS, which typical web browsers don't know how to handle. You'll just get NXDOMAIN if you try and point Firefox at it.

Compatability for various USB 3.0 / PCIe cards ?
Well friends, it's that time of year again... yep, it's shop till you drop time! This year it appears that everybody and his brother is having a sale on compact (mostly 2.5 inch) external drives, and most of them nowadays have a USB 3.0 connection. That's swell, and there are some really good bargains on these things out there... especially today... but there is a fly in the ointment. My older motherboards don't have built-in USB 3.0 support, so I'll need to add that. So I'd like to know what (if any) USB 3.0 / PCIe adapter cards are known to work well with FreeBSD at this time. The cheapest one I found on Newegg was about thirteen bucks, but of course they don't say anything about what chips are on that exactly. There's also a Syba branded one on mazon for about fourteen bucks, and in this case it explicitly says "Asmedia Chipset". So? What works with FreeBSD? (Keep in mind that I don't want to spend much. Oddly enough, some of these things are priced in the low teens, as I've said, but others cost as much as fifty bucks.

Yes. poudriere uses the cloning and snapshotting abilities of ZFS as a fundamental part of the way it works. You can use tinderbox instead if you only have conventional filesystems, but that isn't so easy to use as poudriere. > Second question: At the moment I'm using 'pkg create' to generate > packages from conventionally built ports, 'pkg repo' to create/update the > tarred repo file, and a tiny Python script for HTTP serving.

Basically what the package building software does is take the repetitive chore of typing 'make buildpackage' over and over again, and automates it. Pkg repos built 'by hand' have exactly the functionality as those built using poudriere. You only need a very basic webserver to publish the packages, or you can just use a file:// URL and no HTTP server at all if you're creating packages to be used on the same machine.

This could be a red herring. Or not. But you can't tell without tracing down exactly what the socket is, and what is expected to be read from it. Probably not the first path worth exploring, although you may need to go there eventually. > I would chock it up to network slowness, but I > do not see the same behavior with Firefox, xload, or xclock. That's not a fair comparison, because tunneling a whole X server involves passing a lot more events than tunneling an application to run on your local server. This is particularly painful because the X protocols are highly serial. Is there any particular reason you don't let the X server run remotely and attach to it with something more latency-friendly, like vnc? I would expect that to work vastly better on any OS, just because you get X (specifically, its tendency to head-of-line blocking) out of its own way.

Yup, I just have not had a chance to chase that one down, and
given that it happens once per SSH session, has not been a high
priority. I mentioned it in the spirit of full disclosure.

The VIrtualBox GUI (not the underlying VM console) should be
comparable to Firefox in terms of network load. Yes, xclock and xload
are much lower overhead as they are simpler apps. The difference
between Firefox (measured at under 10 seconds to open the window) and
VirtualBox (measured at 157 seconds to open the window) indicates that
_something_ is wrong.
Sorry if I was unclear. I am running 3 different VMs on this
server (soon to be more :-). One is WIn 2008 server as an RDP host for
a specific application, the others ar FreeBSD VMs, one for DNS and
DHCP, and the other for email / webmail. I manage the underlying Win
2008 instance via RDP (and that is how the end users connect), the two
FreeBSD VMs do not run a window manager at all and they are managed
via SSH connections. I use the VBoxHeadless executable to run the VMs
for production use. Normally I make config changes with the command
line tool VBoxManage, but in this case I had a FreeBSD VM that was not
booting so I needed the console (and to make various changes to the
config).
It is running the VBox management GUI on the physical layer server
that I am having fits with.

The short answer to why X11 via SSH and not VNC for the management
is that I have not found a very clean way to have the VNC service
running for root without manual intervention to start it. Yes, I know
I could script it, but that adds one additional layer that needs to be
supported.
P.S. I did get my VM repaired, very slowly and painfully, but I still
need to track down the VBox GUI issue.
