Re: dhcp server returns core dump when i define network with mask 8
thanks Frank,
192 is just a sample. if i want to define 125.0.0.0 netmask 255.0.0.0, dhcp
server core dump either. you're right, it is better to use just some
limited addresses to avoid possible troubles. but i want to run my dhcp
server for all possible networks.
now my question is: if i define a network with mask 8, the rang should be
like: 126.0.0.0 126.254.255.255?
and thank you jb but if i define my network like below, server runs
correctly:
log-facility local7;
subnet 192.168.0.0 netmask 255.255.0.0 {
range 192.168.0.1 192.168.255.255;
}
i think 192.168.255.55 is reserved for broadcast too. is it not true? if
yes, why dhcp server works correctly?
please help me to clear my mind.
regards,
SAM

It's definitely bad idea to try to use it, but it doesn't explain the
core dump.
Also, using DHCP to dish out addresses that don't belong to you AND aren't
on a private network (as defined by IANA) will probably lead to trouble.
Valid private address ranges are:
10.0.0.0 - 10.255.255.255 (private class A)
172.16.0.0 - 172.31.255.255 (private class B x 16)
192.168.0.0 - 192.168.255.255 (private class C x 256)
Which block you use is really a matter of taste - classes haven't been
used in routing for quite a while so you can consider them all as straight
blocks but I (for one) still treat them as classed just to help me
visualise what's what. For example, I'll use one class C per site to
prevent conflicts over VPN.
192.0.0.0/24 addresses are allocated to real hosts on the wider internet,
although IIRC some of the lower ones are reserved for use in documentation
(like example.com) - is that where the idea came from?!? :-)

thanks Eugene, you're right but i forgot to say that my client acts like a router. i mean none of interfaces should have ip address in same range (this is conflict for me). i can manage each interface to get ip address from DHCP or manually. so one interface may get ip address from dhcp server whereas all others have ip addresses which are set manually. for this situation, do you have any ideas to avoid ip conflict? thanks again for your attention SAM On Thu, Jul 11, 2013 at 3:06 PM, Eugene ge...@geniechka.ru wrote: Hi Sam, Actually I think this is wrong approach.

That's correct and expected for the MBR partitioning approach (which is considered mostly outdated today). i checked FreeBSD handbook, but it doesn't say anything about defining more partitions. Because you _cannot_ define more partitions than up to 'h'. This is a hard-defined limit of MBR-style partitions (as they are initialized with bsdlabel). my question is: how can i define more partitions on my freebsd? (for example, ad3s1a, ..., ad3s1h, ad3s1i, ad3s1j, ...). You cannot. You need to use the GPT partitioning approach and repartition your disk. With gpart, you can create more than 'h' partitions, but the partitions will have different names, such as ad3s1p1, ad3s1p2, ..., ad3s1p10, ad3s1p11, ... and so on. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ 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

This still won't work if the last sector of the partition is in use by the filesystem You'll need a spare partition of some size to be the journal provider, as in the example.

setup journaling for root partition
hello everybody i want to setup a journal partition for my root partition. but i do not know how to do that. in FreeBSD handbook, it is done in single user mode, unmount the desired partition and assign the journal partition to it. i test this procedure and it is done for /usr partition but for root partition, it can not be unmount in single user mode. i try to do it in fixiit mode, but i can not load gjournal. do i use gpart to partitioning my system and enable journaling for root partition? isn't there any way to setup journaling for my existing root partition? which command should be used (or is better to used) to enable journaling? tunefs, gjournal or newfs? please help me to setup a journal partition for my root. thanks in advance SAM ___ 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

If that's what you're after, then the best approach is probably to pick one subdirectory of /usr (/usr/local would be an obvious choice) and restore everything *but* that to one of your disks, then mount the other disk on the subdirectory and restore the rest onto there.

Allow me to provide an example that I've been using on FreeBSD 4 and 5: # PPP Configuration File # See /usr/share/examples/ppp/ for some examples # $FreeBSD: src/etc/ppp/ppp.conf,v 1.8 2001/06/21 15:42:26 brian Exp $ default: set log Phase Chat LCP IPCP CCP tun command ident user-ppp VERSION (built COMPILATIONDATE) set device /dev/cuaa0 set speed 115200 set dial ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \\ AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT set ifaddr 10.0.0.1/0 10.0.0.2/0 set timeout 180 enable dns papchap: # edit the next three lines and replace the items in caps with # the values which have been assigned by your ISP. set phone PHONE_NUM set authname USERNAME set authkey PASSWORD set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0 add default HISADDR mymodem: set phone 01234567890 set authname myname set authkey mypass add default HISADDR The example name I've chosen here is mymodem. Change it to something meaningful. :-) The essential authorisation data here is the phone number of 01234567890, the username 'myname' and the password 'mypass' Note that today it may be required to change the device name! I haven't tried to do anything with a modem on current FreeBSD, so I can't be more specific, sorry. The device name /dev/cuaa0 will probably need a change. And then set speed 115200 sets the speed you need. If you've done everything properly, you would do something like # ppp mymodem ppp dial Then the modem should dial. With close you close the connection. There are options for /etc/rc.conf (the ppp_* variables) that allow you to automate things, like dial on demand. In contradiction, in /etc/ttys something like ttyd0 /usr/libexec/getty std.9600 dialup on secure would enable you a serial console access (e. g. to connect a serial terminal to) at a speed of 9k6 (e. g. a DEC vt100). When connected via serial cable, you would receive a login prompt. Again, note that ttyd0 might not be valid here. -- Polytropon Magdeburg
getting packets on a specific port by pf
hello guys i have a problem with getting packets which are diverted to a specific port by PF. i mean i diverted my packets to a specific port by IPFW and want to get these packets by PF to change them. i used ipfw add 1000 divert 8000 all form any to any command to divert my packets. how can i get these packets by pf on port number 8000? pf has divert-reply option. should i use it to get packets? how? any comments or hints are really appreciated. thanks, sam ___ 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

marking packets in IPFW and recognize them in PF
hello every body i want to mark some of my packets (by tag, mark, divert or anything else) in IPFW and recognize these packets in PF in the same system. please let me know if it is possible and how i can do that. i have freebsd 8.2. if it is impossible in freebsd 8.2, what about freebsd 9? can we do it in freebsd 9? thanks SAM ___ 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
config multiport serial card
hello everybody i have a moxa 4-port serial card and installed it on freebsd8.2 successfully. i have ttyu2-5 in /dev that are moxa ports. my question is how i can use these ports? i add the following lines to ttys file: ttyu2 /usr/libexec/getty std.9600 vt100 on secure ttyu3 /usr/libexec/getty std.9600 vt100 on secure ttyu4 /usr/libexec/getty std.9600 dialup on secure ttyu5 /usr/libexec/getty std.9600 dialup on secure and restart my system. i connect another system to one of my moxa port by a null modem cable and run putty in both side but i can't see any thing in putty screens and leds on moxa card doesn't turn on. please let me know if i should do some configuration else in order to my ports work correctly. should i use another application instead of putty to work with these ttyus? thanks sam ___ 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
Re: find slot number and number of ports for each card

(pciconf -lv for verbose listing). Two important notes about pciconf -l… 1. It lists more than just cards 2. The type can't always be determined by FreeBSD When looking at the output of pciconf -l, each line represents a component (this can be an integrated component on the mother- board, such as USB port, not necessarily a PCI add-in card). If the line begins with none@ then a driver has not attached to this device (and FreeBSD therefore doesn't know what type it is). In this case, you'll want to look at the chip= portion of the line. The chip= portion of the line gives you two very important pieces of information when it comes to identifying your hardware: a. The 4-digit hexadecimal identifier for the Model of the device b. The 4-digit hexadecimal identifier for the Vendor of the device (in that order from left-to-right) Let's look at a sample line: vgapci0@pci0:2:9:0: class=0x03 card=0x00081002 chip=0x47521002 rev=0x27 hdr=0x00 NOTE: That's my graphics card on an ASUSTek P4B533 motherboard In the above line, see chip=0x47521002. In this case, 4752 is the Model identifier and 1002 is the Vendor identifier. If you're a human and you want to know what these numbers are, you hop on over to pcidatabase.com and punch in the numbers to find out that this is a [particularly ancient] ATI Rage XL graphics card. If you're not a human (i.e., a script), you'll instead reference a local copy of the pci.ids (/usr/local/share/pciids/pci.ids for example): $ grep '1002 4752' /usr/local/share/pciids/pci.ids 1002 4752 Proliant Rage XL the number of ports that each card has That one is near impossible. Since every add-in card is going function differently, you really need a device-specific enumeration method to (for example) count things like PHYs provided by a single NIC. Imagine if you will, the case of the card for which there is no driver loaded in the kernel (where pciconf -l shows a none@ prefix). There really is no way to enumerate the number of ports a card offers in that circumstance. However! You can build logic into your code (if you are scripting something) that takes the description from the pci.ids file (or just the raw hex IDs) and extrapolates based on prior-knowledge how many ports a particular device has. and the slot number which cards are installed. That's provided by pciconf. Also, it's worth mentioning the excellent dmidecode tool from the ports tree. This too can enumerate the slots themselves (and tell you whether they are PCI, PCI-X, PCIe, etc. including voltage. Search for System Slot Information in the dmidecode output for this info. -- Devin This is interesting. I'm glad this question was raised, because i've noticed i've got two none@ lines listed when using pciconf -lv. I've been trying to figure out what these are over the last week but to no avail. They must be there for some purpose and I wondered if i'm missing some important driver because of this. ___ 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 ___ 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
Re: how restore an unencrypted dump on an encrypted file system?
thanks saeedeh OK i try to explain what i have done more in detail. i want to restore unencrypted dump files on an encrypted file system. in order to do that, i encrypted my file system by geli command and sure that is done correctly because when i install base and kernel on it, freebsd start up successfully. problem is here: when i restore my dump files and restart my freebsd, boot PXE menu is shown and i select my freebsd but after that, the error message invalid format occurs and i see this message: FreeBSD/i386 BOOT Default: 0:ad(0,a)/boot/loader boot: it selects the default kernel correctly and after some seconds an error message is shown which consists of some hardware addresses. i don't know how to fix it. any hints that might fix my problem are appreciated.
