Re: USB-Serial adapter, how to make /dev/cuad* appear? [Solved]
I finally figured this out. Turns out the FreeBSD side of things worked from the start, and it was the hardware that was broken. A replacement adapter works like a charm. Oh and yes, Oliver, you're perfectly right, /dev/cuaU0 is indeed created by ucom. I was confused by the device having the creation date of when the system was booted, even though it was dynamically created a couple of days later. Thanks for all your help!

You enable ip forwarding with the net.inet.ip.forwarding and net.inet6.ip6.forwarding sysctls. However, if your gateway already works for the internal net, I strongly suspect those sysctls are already set to 1. I'd have a look at your firewall ruleset.

IP broadcasts
Hello, I've been playing around with IP packets tonight, and I've noticed a peculiar behaviour in FreeBSD that I can't explain. Can someone provide some insight? Specifically, I've been sending IP packets to broadcast addresses, once to 10.0.0.255, which is the local subnet's broadcast address, and once to 255.255.255.255, which as I understand it, is a general broadcast address. The first broadcast (to 10.0.0.255) works, the second (to 255.255.255.255) doesn't. Looking at it with tcpdump on the sending machine, I see this: 05:46:52.057994 00:12:17:5a:b3:b6 ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 136: 10.0.0.1 10.0.0.255: ip-proto-255 102 05:47:16.472315 00:12:17:5a:b3:b6 00:40:63:d9:a9:28, ethertype IPv4 (0x0800), length 136: 10.0.0.1 255.255.255.255: ip-proto-255 102 In other words, the packet to 10.0.0.255 is has a destination MAC address of ff:ff:ff:ff:ff:ff, so all machines on the subnet receive it. The second packet has the destination MAC of my gateway, so only that machine receives it, the other machines on the net don't see it (the ethernet uses a switch). Things work as expected when sending the packets from a Linux machine. Maybe there's some socket option or sysctl I need to set? Cheers Benjamin pgpfiAPFRsTKa.pgp Description: PGP signature

It appears that the only way to upgrade in binary form is to use pkg_delete -f to remove each package, e.g., expat 1.98, and then pkg_add to get the newer (2.0) version. And then you have to be extra careful with dependencies between packages. [...] portupgrade actually does support packages as well. Use the --use-packages switch.

First, here's the relevant section in the handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/config-network-setup.html Now, for network connectivity to work properly, you need three things: The interface must have an IP assigned to it, you need routing information (usually that means that you need to set a default route yourself, routing for your subnet is configured automatically when you set an IP), and last you'll probably want to have a DNS server set. If you are using DHCP, you need this entry in /etc/rc.conf: ifconfig_rl0=DHCP and everything should work. If you don't have DHCP, or you wish to check the settings you got through DHCP, do this: * You can see your current IP by typing ifconfig. You can assign a new IP with ifconfig rl0 1.2.3.4. You can automatically assign an IP on startup by adding the following line to your /etc/rc.conf: ifconfig_rl0=inet 1.2.3.4 netmask 0xff00 * You can see the current default route (also referred to as default gateway) by typing netstat -rn. The line starting with default (or 0.0.0.0 on Non-FreeBSD systems) is your default route. If you don't have one, you can set one with route add default 1.2.3.4. The IP you specify there should be the IP of your firewall or router. To make this setting apply on startup, add this line to your /etc/rc.conf: defaultrouter=1.2.3.4 Again, the IP there is your router's IP. * You can see the currently set DNS server by looking at /etc/resolv.conf. You can add DNS servers my modifying that file. A correct entry looks like this: nameserver 4.2.2.4 If these settings are all correct, and you still don't have connectivity, the cause is one of the following: * Your networking card is broken. Your Realtek card is of extremely low quality, and they break frequently in unexpected ways. I know, I've had it happen to me too. * You have a firewall active on your FreeBSD system. FreeBSD ships with three different firewalls. The simplest thing is to disable them for now. PF you can disable with the pfctl -d command. IPFW you can disable with ipfw disable firewall. And last, ipf you can disable with ipf -D. * Your IP settings are simply incorrect, but you don't recognize that. If you still haven't solved the problem by now, post some more details, like the output of the ifconfig and netstat -rn commands as well as the general layout of your LAN. Hope this helps!

Even if it were so, for me it is too much trouble to import every key into my key-database from a key-server. I sign emails for the same reason I sign my snail-mail letters with a pen. I like providing authenticity. Whether the recipient actually checks the signatures is not that important, important is that if the need or desire arises, he can. I don't import every key I come across either, usually only those keys for which I get signatures on a regular basis. On the other hand, those who aren't able to read singed messages are confronted with a lot of carbage tekst wich makes the posting harder to read. Most people use PGP/Mime these days. If your mail client does not support PGP, the signature will be surpressed or maybe shown as attachment. Either way, that doesn't make the mail content harder to read. And if your Mail client doesn't support Mime yet, well, that's your choice, and seeing the signature plaintext is far from the worst inconvience you'll have to put up with in that case. We don't send postings in .html for that same reason. That's different. Html text means there's no readable content at all for non-HTML mail readers. And these are quite common. I sign my emails for two other reasons. First, I'm advocating adoption of PGP by everyone. I wish to sensitize people for the facts that standard emails are neither private nor authenticated, and that you can achieve these very important things with PGP. Frankly, I find it staggering how many people send around confidential information in emails over the public internet, without thinking of the consequences. The second reason is very personal. It takes some effort on my part to sign email. I am not using any key agent, which means I enter my keyphrase every time I send an email. This makes the process of sending an email more conscious for me: I think twice whether I really want to send it. Sometimes times I've stopped myself from sending an email I would later regret (a flame, or an angry answer, something like that) at the signing stage. It means that sending an email is not as much of a fire-and-forget thing for me. I like that. Cheers Benjamin pgpXG3LWRXQln.pgp Description: PGP signature

Right now, we are only two in this very big team. :-) I'm just wondering if I will ever gonna finish this project or not. I have a lot of stuffs mixed up in my mind right now but I really don't know where to start. If you don't have it already, I'd start cleaning up the old system without changing it's structure. Remove the redudancies, eg unnecessary cascading switches, or computers that are no longer used. This will give you a clear idea of what the current layout looks like, making it easier to plan changes, and with some luck it'll also give you a hardware stockpile that you can then recycle for your new LAN. I have these in my mind right now: Connectivity 1. wired 2. wireless I see no place for a wireless network in a professional network. It's hard to secure it (it's possible, encrypted-VPN-over-WLAN works, but it's difficult and expensive to set up). Stick with a wired LAN, and there'll be one security threat less that you have to worry about. Machines being hooked into the network: 1. servers 2. workstations Make a list of the servers you have, and which user groups need them. Make a list of which logical user groups there are. Then design a network layout to match those needs. You could, for example, put each use group into its own subnet, including the servers it needs. Access between user groups could then be restricted at will*. Alternatively, put some or all servers into a dedicated subnet. This will also allow protecting them better. I realize I'm being very unspecific, but you didn't give us all that much information. 3. testbeds If there are users accessing those, treat them as servers. Otherwise, isolate them from the production network. 4. personal (laptops etc.) This is a difficult one. Personal laptops are machines you have no direct control over (you cannot control what software is installed on it), and as such they are a high risk factor when they are connected to your network. They might introduce malware into the company, or evade your file storage procedures. This is a matter of policy basically. Try to restrict personal machines as much as you can. Forbid connecting them to the LAN. If you can't do that, maybe have specialized laptop ports that are firewalled off from the rest of the network. Will use DHCP Keep in mind that a DHCP server needs to be in the same subnet it serves. Other services do not have this requirement. Will use centralized directory service Will use centralized authentication Sounds good. Personal laptops will undermine this though, another reason to try to keep them away. We have at most 150 employees... We don't have that much to spend on equipments like managed switches, powerful servers, etc. We have a lot of political issues that needs to be resolved regarding network usage policies You don't need powerful hardware to manage a network with just 150 employees. Some gigabit hardware for popular servers would be nice, but the network management will use very little CPU resources (unless of course you decide to play around with VPNs).

I really have no idea where to start aside from creating a purchase request for a new PC router and a multiple port lan card, which I already did a week ago..And it has not arrived yet. :-) It sounds like you're planning to have all subnets connected through this one FreeBSD box. This is not necessary. You can put a router in between subnets, and have that one located elsewhere, where it's more convenient. It can also make perfect sense to have firewalls on these routers. If you isolate user groups that need to communicate with each other into different subnets and block traffic between them, it'll be easier to contain a worm outbreak. And oh yeah: in my opinion, the firewall, ie the outermost machine that's connected to the internet, should have 2 or 3 interfaces only, and carry data only on 2 of them. Do not give it several interfaces for the purpose of routing your LAN. It'll make creating an airtight firewall ruleset much more difficult. Instead, have one or several routers inside your LAN that handle it, that don't need to deal with malicious outside traffic too. Please help me.

I tried PC-BSD a couple of weeks ago. What they seem to do is include all the necessary libs with a program, and install each program into a dedicated library. So while there is bloat, a library hell there shouldn't be. Cheers Benjamin pgptKaoLS1aOB.pgp Description: PGP signature

assigned symbols in /usr/X11R6/lib/X11/xkb/keycodes, and those symbols
are then assigned Keysyms in /usr/X11R6/lib/X11/xkb/symbols.

device numbering / glabel
Hello, I've run into a little problem with device numbering. My boot device is a SATA RAID5 array, which normally shows up at /dev/da0. Now I've connected an external USB HD, which showed up at /dev/da1. So far so good. The next time I booted, I was surprised to see the USB disk now having /dev/da0, and the RAID array having /dev/da1. The machine dropped me into single user mode because /etc/fstab was now wrong. Now, it's clearly not a good thing to have one's boot device name change depending on whether an USB HD is connected or not. I figured I could use glabel(8) to set a label, and then use that. Setting the label for both RAID array and USB disk worked. For the RAID array, dmesg does say: GEOM_LABEL: Label for provider da0 is label/raid5. However, the label doesn't show up in /dev/label, there's only the label for the USB disk. Any idea how I can solve this? Connecting the USB disk after booting is not an option, since this system's supposed to be headless, and I'd like to be able to remote reboot it.

Re: How to properly mount a DVD-R/W drive and how to use it from the command line?

To mount both CDs and DVDs use either: mount_cd9660 /dev/acd0 /cdrom (The system must know what kind of filesystem you want to mount. It does not figure it out on its own like Linux does.) If you have an /etc/fstab entry for the file system you wish to mount (which you do, in this case), alternatively you can use the short version: mount /cdrom This fetches the necessary information from /etc/fstab. However: what should the proper settings be for a DVD-RW drive? Surely at least the 'ro' flag is incorrect, but is that all? No, that is correct. I don't think FreeBSD supports packet writing. In other words: If you wish to (re)write a DVD, you need to use a proper burning program (eg the somewhat misnamed growisofs), you can't just copy files to it by mounting it. Also: are there other locations where I should tell FBSD (and if so: how) about the presence of the new drive? FreeBSD will automatically detect any drives. Under FreeBSD 4.x, and with exotic configurations, it was sometimes necessary to manually create devices nodes. Finally: I do not intent to run X on the machine, as it'll be a webserver only (well, incl. DB stuff etc.), and the drive is intended for being used to make remote back-ups on DVD-RW (yes: someone will physically swap the DVDs when necessary ;) ). What I'd like to know is what the easiest/best ways are to do so from the command-line. Does anyone have some scripts for this? Or perhaps some pointers to a good (preferrably free) program or tutorial? Use some program to produce an iso image of the files you want to burn (check the cdrtools port), then use growisofs to burn that iso.

Re: Gnome install in FreeBSD?

However, there is a problem: all my previous softwares were installed manually, could ports check it out to avoid install some dependencies (like GTK+) twice? Yes and no. The ports checks their dependencies by looking for files installed by other ports. If you installed all your software in the same place that the ports would have installed them (ie, /usr/local for most, /usr/X11R6 for some), the gnome ports will not rebuild that software. Of course, it'll just record that dependency port as installed even though it isn't, which might give you problems later on. Cheers Benjamin signature.asc Description: OpenPGP digital signature

Problems with make -j
Hello,
As a pet project I've started to change /etc/rc so it uses make(1) to
execute the scripts in /etc/rc.d instead of executing them one after the
other like the standard /etc/rc does. The goal of the project is to speed
up boot time by executing rc.d scripts in parallel.
Now, if I don't specify a -j parameter this works just fine. I've written
a script that generates a Makefile with all the rc.d dependencies in it,
and using that the system boots just fine.
As soon as I add a -j parameter to make, even -j 1, things break though.
Scripts (eg, rc.subr) are being spewed to the screen several times, and
execution hangs at /etc/rc.d/adjkerntz (I think). I can pipe all this to
a log file with make.log 21. By the time make gets to adjkerntz and I
ctrl-c it, the logfile is slightly above 3MB.
Can anyone tell me why make behaves like this? If I had to guess I'd say
something's happening to the file descriptors, or something that make
needs for -j to work has not been set up. Btw, I have set up a memory
disk in /etc/tmp that make can use for -j (and I've patched make to use
that patch).
Here's what I use in /etc/rc now:
= SNIPPET START =
RC_MAKE=1
if [ -z $RC_MAKE ]; then
skip=-s nostart
[ `/sbin/sysctl -n security.jail.jailed` -eq 1 ] \
skip=$skip -s nojail
files=`rcorder ${skip} /etc/rc.d/* 2/dev/null`
for _rc_elem in ${files}; do
run_rc_script ${_rc_elem} ${_boot}
done
else
skip=-DSKIP -DNOSTART
[ `/sbin/sysctl -n security.jail.jailed` -eq 1 ] \
skip=$skip -DNOJAIL
/sbin/mdmfs -M -S -o sync -s 5m md0 /etc/tmp
/bin/rc_make -i -f /etc/Makefile ${skip} PARAM=${_boot}
/sbin/umount /dev/md0
/sbin/mdconfig -d -u md0
fi
= SNIPPET END =
Here's two example targets from the /etc/Makefile:
= SNIPPET START =
abi! LOGIN archdep
.ifdef !KEEP || NOJAIL
.ifdef !SKIP || (!NOJAIL)
. /etc/rc.subr run_rc_script /etc/rc.d/abi ${PARAM}
.endif
.endif
accounting! mountcritremote
.ifdef !KEEP || NOJAIL
.ifdef !SKIP || (!NOJAIL)
. /etc/rc.subr run_rc_script /etc/rc.d/accounting ${PARAM}
.endif
.endif
= SNIPPET END =
This currently works. As soon as I add -j 1 or -j 2 to the rc_make
call above, I get the behaviour described above.
Note that rc_make is standard make(1) except that TMPPAT has been changed
from /tmp to /etc/tmp.

In combination with IMAP_EMPTYTRASH=Trash:7, which removes mails from the trash folder after 7 days, this solution is comfortable, as long as the mail client has support for deleting/expunging in one step (I use sylpheed with X, which does this well, and mutt does it well enough too. I have not used evolution). Basically I don't use the classical IMAP way of deleting mails (just marking them with the deleted flag) at all. - Benjamin pgp0.pgp Description: PGP signature
where is late (scheduler testing tool)
I've been reading Jeff Roberson's ULE paper - very interesting. He uses a tool called late for testing. Where can I find this tool? He says that it should be available in FreeBSDs source repository, but I'm unable to find it. Can anyone point me towards it? Thanks. - Benjamin pgp0.pgp Description: PGP signature
memory categories
I'm trying to understand what FreeBSD uses its memory for. Unfortunately, I've not been able to find documentation that answers all my questions, so I'm hoping someone on this list can answer them. Let's start with top(1)'s memory categories: Free: Not used for any purpose. (vm.stats.vm.v_free_count) Active: Used by userland programs. (vm.stats.vm.v_active_count) Cache: Well, this obviously caches something... but what? Filesystem? (vm.stats.vm.v_cache_count) Inactive: This seems to be the biggest chunk of memory on my system. What exactly is the meaning of this? Someone explained it as memory that a program has grabbed that isn't currently being used. It can be swapped to disk if RAM is needed by other programs.. How does the system know that this memory is not being used? Is this the difference between the RES and SIZE colums in top(1)'s output? (vm.stats.vm.v_inactive_count) Wired: I've only been able to figure out that this is memory that's being actively used and that cannot be relocated in any way. Could someone explain this in a bit more detail? What exactly is the difference between active and wired memory? (vm.stats.vm.v_wired_count) Buf: I'm puzzled... If I add up Free, Active, Cache, Inactive, Wired and Buf, I get more memory than I have physically installed. I could not find a sysctl that represents this value. Also, .v_free_count, v_active_count, v_cache_count, v_inactive_count and v_wired_count add up to vm.stats.vm.v_page_count... where does this Buf come from? And some more questions: On my system, these sysctls have these values: hw.physmem = 1064734720 = 1015.410MB hw.usermem: 947351552 = 903.465MB hw.availpages = 259945 vm.stats.vm.v_page_count: 255299 vm.stats.vm.v_page_size: 4096 hw.availpages * .v_page_size = 1064734720 = 1015.410MB .v_page_count * .v_page_size = 1045704704 = 997.262MB I have 1024MB of RAM installed. Why is hw.physmem inaccurate? And why is .v_page_count * .v_page_size less than hw.physmem? Is the difference between hw.physmem and hw.usermem used for the kernel? If yes, 112MB seems to be a huge amount? Phew... quite a few questions... Let's see what answers you can give me! Benjamin pgp0.pgp Description: PGP signature
Re: FreeBSD Version...
I am wondering why there was 4.9 release if the newest one it 5.1. Whick is better I am currently on 5.1. It's a little confusing. Well there be a 4.10 and 5.2 release at the same time? 4.9 is the stable production release, while 5.1 (and in a few weeks, 5.2) is the development release that will eventually become the stable release. FreeBSD 4 will be developed (well, maintained, since few new features are added to it at this time, mostly driver updates from what I've seen) until the development team thinks FreeBSD 5 at least as fast and rock solid as FreeBSD 4. This is planned to happen when FreeBSD 5.3 released; at that point, active development for FreeBSD 4 will halt. FreeBSD 5.1 is a development release. While it runs OK for most people, some architectural things are going to change with 5.2 and 5.3, and you're advised not to rely on it with your critical stuff, but use 4.9 instead. Hope this clears things up. Greetings Benjamin pgp0.pgp Description: PGP signature
lockup in FreeBSD 5.1
Hi, I have a friend for whom I installed FreeBSD 5.1. Recently, the box has started acting up... programs like dhclient would freeze, driving the load up to above 3. If killed, some other program would freeze minutes later. I've been puzzled by this behaviour, since I run 5.1 on two other machines without problems, and I haven't heard anything like this from others running 5.1. Maybe someone has an insight? The interesting thing is - today I was watching the machine with top, while she used it normaly (me = maxlor, her = theres). Below you find what top displayed before the machine went offline (I assume she powercycled it). The interesting thing is that multiple processes seem to be locked in Giant... could this be a driver issue? On the hardware side, we have an old K6 machine, with some NIC that uses the vr driver; the other stuff I can't remember right now. Anyone have an idea what I can do about this?

Re: modern (usb) webcam support?
My searches for information on webcam have not found much, except for some sites which say FreeBSD does not support USB web cameras. My Creative Labs USB Webcam (older Model, Webcam Plus or something it was called) runs ok with /usr/ports/graphics/vid, which supports Webcams with the OV511 and OV511+ chipsets. I don't know for sure if the newer webcams still have this chipset, but I guess they do. Oh, you'll need to code some glue to make vid be useful; all it does is grab an image and write it to stdout, no configurables.

dc NIC: mac address gets reset (5.0-REL)
I just installed FreeBSD 5.0-RELEASE on a machine that was running 4.7-RELEASE-p3 before. I've got a problem with my network card: After rebooting the system, it's MAC address is reset to C0:00:C0:00:C0:00. The card works fine otherwise (apart from some dc: failed to force tx and rx to idle state messages that are, as far as the mailing lists tell me, uncritical). This of course makes the DHCP server give me another than my standard IP. Also, if I install FreeBSD 5.0 on another machine in my LAN, and it shows the same behaviour, i'll run into problems. I can manually change the MAC address back to its old value, then restart dhclient, and it works. However, I don't want to have to do that after every reboot... Here's the relevant lines from dmesg: - PASTE START - dc0: Davicom DM9102A 10/100BaseTX port 0xd000-0xd0ff mem 0xef00-0xefff irq 11 at device 11.0 on pci0 dc0: Ethernet address: c0:00:c0:00:c0:00 miibus0: MII bus on dc0 dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state dc0: failed to force tx and rx to idle state - PASTE END - Any ideas?
