Re: Backspace
Thanks for helping everybody. But actually I'm using Bourne shell on FreeBSD 6.1 just like the Solaris in lab, and the FreeBSD is freshly installed, I have checked .shrc and .profile, but nothing related to key bindings or stty's there, so what I thought it should be is: after I login - [press backspace] - ^H appears - [press DEL] - ^? appears in emacs - [press backspace] - oops, help appears I think Solaris was just like the above. But in my FreeBSD, things go like: after I login - [press backspace will erase last char] - [press DEL does the same thing] no matter what have I done to stty like stty erase ^H and stty erase2 ^H, the result is just the same, backspace and DEL still can be used to erase last char in shell. The only difference is in emacs, but I searched the net and found that emacs relies on its own definition of key bindings in ~/.emacs file (it is empty in this case), rather than the terminal key bindings. Totally confused. Any idea? Thanks again for you kind people. 2007/8/13, Jerry McAllister [EMAIL PROTECTED]: On Sun, Aug 12, 2007 at 01:31:36PM -0500, Derek Ragona wrote: At 10:54 PM 8/11/2007, d.Z. wrote: Hello, I'm a new user to FreeBSD and Unix. I used Solaris 10 last week in lab, and found there is a difference between them. When Solaris is installed, press backspace will give you ^H, you'll have to stty erase ^H to solve this problem. But with FreeBSD 6.1, when first installed, backspace is always bounded to erase last character, even I have stty erase ^? and stty erase2 ^?, backspace still deletes last character input. Does any body know why is this happening? Solaris by default uses csh for user accounts. The backspace key assignment and for that matter, all key assignments are dependent on the both the shell and terminal definition. Reassigning keys is typical for your shell's startup profile file .cshrc for csh and .bashrc for bash. And strange thing is with default setting (before stty erase and erase2 to ^?), when I use Emacs, C-h will give me back space, instead of help. I know this is desirable for experts, but I'm really new so just want to follow the instruction first. Applications like the shell you use interpret the terminal definition and may or may not use the same key assignments. Most applications like the shells in UNIX environments have startup files to customize the key assignments and in the case of editors even define macros. And those startup files are: For csh and tcsh (tcsh is the most common one in FreeBSD) the startup file is .cshrc in one's home directory. You can also create a system-wide one. For SH and bash it is .profile and for them don't forget to export any variables. jerry Hope this helps. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

uncalled for reboot
Greetings to all, I am attempting to run cvsup-without-gui on a Dell Inspiron 1501, with amd64x2 processor and 2GbRAM. I am using the ports-supfile modified to suit location and RELENG_6_1. The process begins, and starts deleting the old stuff...no problem. Then, about 10 minutes into it, the system reboots all by itself - no apparent reason. Any ideas? Season's Greetings, Z.

FreeBSD version, hardware data, etc ... Thanks Bill. I'll keep that in mind. I think I have the problem figured out. *base=/var/db was set in the supfile. After changing it to /usr, the problem went away. Regards, ZWH However, spontaneous reboots are almost always hardware problems. Have you verified that your RAM, hard drive, cooling, power, and all other hardware factors are in proper operation? That would be the first logical step in diagnosing this. -Bill ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
nonstandard ports
Hello to all, Not long ago, I ran cvsup successfully. In the example cvs-supfile, the following opening lines exist: # base=/var/db # This specifies the root where CVSup will store information # about the collections you have transferred to your system. # A setting of /var/db will generate this information in # /var/db/sup. Even if you are CVSupping a large number of # collections, you will be hard pressed to generate more than # ~1MB of data in this directory. You can override the # base setting on the command line with cvsup's -b base # option. This directory must exist in order to run CVSup. # # prefix=/home/ncvs # This specifies where to place the requested files. A # setting of /home/ncvs will place all of the files # requested in /home/ncvs (e.g., /home/ncvs/src/bin, # /home/ncvs/ports/archivers). The prefix directory # must exist in order to run CVSup. I attempted running cvsup with base and prefix locations other than the ones stated above; and, it did not work. However, when I edited the supfile as described above, the whole process ran to completion, successfully. Well, now I have an updated ports tree in /home/ncvs/ports instead of /usr/ports. So, my question this morning is what do I do with that? Do I treat /home/ncvs/ports as if it were /usr/ports? Do I copy the entire /home/ncvs/ports directory to /usr/ports for updated ports? Thank you in advance for directives. Z.

cvsup and amd64
Greetings to all, I'm running a dell 1501 laptop with amd64x2 processor. I got a disk from a guru specifically for this architecture, booted it, and installed 6.1 via FTP. Yesterday I ran cvsup successfully. Today I did make buildworld successfully. Now, I have a little paranoia about buildkernel. Please tell me, did I need to specify anything specifically about the amd64 architecture when running cvsup? Did I possibly get a GENERIC kernel file through cvsup that is not compatible with amd?

strange events
Greetings to all, And, please forgive me if this is a bone-head question(s). I'm running, once again after 4 years, freebsd 4.2. In KDE, with netscape or kfm I can only access my own web domain, which is www.oldpathsbaptistchurch.org No matter what else I put into the URL box and submit, it trys to find the other URLs, but then resorts back to www.oldpathsbaptistchurch.org. I must have done something wrong in initial setup/config, but after checking through lots of stuff, I see no reason for this to happen. Also, I get STOP error code 1s when I try to make lynx from the ports collection. Could someone have a little pity on this old stoner from the 60's and lend some advice? Thanks in advance, Z.

ccd usage
Greetings, I'm planning a new install and my question regards the usage of ccd. I have two disks of 30G and 20G. Is it possible to use ccd to create a single /usr partition across these two disks? How might this be done? Can it be done from the sysinstall menu off the boot disk or will I need to do some toying around after initial install is completed? Also, while not part of the ccd question, if I'm not mistaken, I can create multiple swap partitions to spread swap usage across multiple drives. Is this true? Thanks in advance.

NAT / ipfw / GW - FreeBSD 4.10 to Linux Private Network???
Hello All, So with the help of all of you I have configure my FreeBSD 4.10 gateway. I am able to ping, tracerout, ssh and call webpages with a fully functioning DHCP client. I thank all of you from the bottom of my heart, those of you that helped me out... its been hardwork and late nights (or early mornings) building these computers from scratch and then introducing them with Linux and FreeBSD OS's which I have only a combined year of experience. With that said I have come to the final component of my network... the NAT component. I was trying to play around with it until I found out that I really didn't know what I was doing... so here I am again. I'm trying to configure one box through NAT via my FreeBSD gateway. I figure after I do it once I'll be able to tweak it for the rest of my machines. This is my set up [internet] - [firewall/gateway] -- [ linux box ] 24.199.105.0-- 192.168.1.1 - 192.168.1.3 ( dc0 ) ( txp0 ) ( eth0 ) I'm trying to get internet connection for my linux box, and I also want all pop3, smtp and http passed to my linux box as well. The freebsd box is setup to be headless once I get this configured properly. In addition I would like SSH2 to be able to tunnel from box to box as well as SSH2 outside my network with my Linux box. I have attached my config files for ipfw.rules, rc.conf, and natd.conf however natd.conf is where I am lost I don't exactly know the rules for natd.conf. I reviewed my resources: The Complete FreeBSD by Greg Lehey and Absolute BSD by Michael Lucas however there was not much on the actual syntax. If someone could help me in these areas it would be greatly appreciated. Thanks in advance... Hakim Z.

Re: DHCP and rc Questions For FreeBSD 4.10???
Bill FreeBSD-Questions,
This configuration is not as intuitive as I thought it would be.
In /etc/rc.conf I added the following strings:
network_interfaces=lo0 dc0
ifconfig_dc0=DHCP
Then I deleted the entries in dhclient.conf and relied on the
default. I started the daemon by [dhclient dc0] and it
seemed to be processing. However, that was all that
happened. When I [ifconfig dc0] I get this return:
#
[EMAIL PROTECTED] ifconfig dc0
dc0 flags = 8843UP, BROADCAST, RUNNING, SIMPLEX,
MULTICAST MTU 1500
inet6 fe:80::2c0:f0ff:fe79:4ab7%dc0 prefixlen 64 scopeid 0x1
inet 0.0.0.0 net mask 0xff00 broadcast 255.255.255.255
ether 00:01:02:c3:40:1a
media Ethernet auto select (100basefull duplex)
status: active
###
Then I tried to ping a host...
###
[EMAIL PROTECTED] ping www.yahoo.com
[EMAIL PROTECTED] ping 24.199.105.1
[EMAIL PROTECTED] ping www.absolutebsd.org
Ping: Cannot resolve www.yahoo.com
hostname lookup failure, etc.
###
However somehow when I run a report the system
indicates that UDP packets are being transmitted but the
statistics are highly skewed at a rate of
11290 IKPTS : 38 OPKTS
I was reading Greg Lehey's book The Complete
FreeBSD which happens to have more information on
DHCP,DNS, BIND than Absolute BSD by Michael Lucas and
Greg says that in order for dhcp to work you must start dhcpd,
am I reading this correctly. I assumed that dhcpd would provide
DHCP for the private network (in my case), I did not think that
my default gateway would rely on dhcpd in order to function.
Now I have 2 questions:
*must I configure dhcpd now?
*must I configure dns (resolv.conf, named, etc.)?
*does DHCP rely on the two configurations list above to data?
Thank you in advance for your help?

Wrap your likes around 72 characters.
All you need in /etc/rc.conf is:
network_interfaces=lo0 dc0
ifconfig_dc0=DHCP
Everything else you added is just re-affirming the default values.

Hi All,
I've been researching this issue although it may be minor I don't like to rely on
the [EMAIL PROTECTED] unless I have to. I'm sure you understand...anyway,
http:www.freebsddiary.com has a tutorial that with info I could not find in The
Complete FreeBSD or Absolute BSD. It described two entries; one in dhclient.conf
and the other in rc.conf. See Below:
###
dhclient.conf
###
interface dc0{
send host-name redgate;
request subnet-mask, broadcast-address, routers, domain-name-servers, domain-name,
time-servers;
require domain-name-servers;
###
rc.conf
###
ifconfig_dc0=DHCP #IS THIS VARIABLE DECLARATION CASE SENSITIVE???
hostname=redgate
###
The question I have now is if this is all I have to do to get dhcp running at
startup? I anyone else has any suggestions they are welcome. Unfortunately I cannot
test this until the evening so feedback will be very helpful and will save me some
time researching. Thanks in advance.

Subject: DHCP and rc Questions For FreeBSD 4.10???
Hi All,
I have installed FreeBSD 4.10 to serve as a headless gateway/router/firewall/NAT.
The first problem that I have run into can probably be resolved easily. I tried to
configure my NIC card via sysinstaller. However, rc.conf does not have a startup
variable for dc0. Therefore dhclient is inoperable.
I built this box to be headless therefore it is low-tech with no floppy or flash
drive and is currently a stand-alone machine so I am not able to copy the rc.conf
file to this post. dc0 is working because I can bring its status to active
manually: '[EMAIL PROTECTED] ifconfig dc0 ether up'.
I was wondering what what variables should be assigned to rc.conf, the related
variables I have thus far are:
##
ifconfig_dc0=dhcp
dhcp_program=/sbin/dhclient
dhcp_flags=
##
It would be appreciated if someone could attach or copy an rc.conf file for a
similar system configuration. Thanks in advance.

Who manages your DHCP server? The config I described has worked in every configuration I've ever dealt with (and that's quite a few) so there is definately something external causing the problem. I have an Earthlink Highspeed Cable account w/ DHCP Server Did you install a packet filter when you set this box up? Yes, however I turned firewall to [firewall_enable=NO] and commented all firewall entries in the rc.conf file. If you don't have a DHCP _server_ on your network, then the DHCP _client_ will not be able to to its job. Earthlink should provide a DHCP server, when I had my standalone redhat box it was configured and I was also receiving DNS as well through earthlink.

You must really like the # symbol. Actually what I realized is that these posts end up on google searches and all sorts of places all across the web. Since people maybe referencing these threads to help solve their problems I take little extra time to make sure that my posts are legible reads as well as I can make at the time and organized in a way to use at your terminal if necessary. Have you tested basic network connectivity? I installed FreeBSD on Tuesday Night and on monday I had Redhat running perfectly fine on the same network connection and cable. I reduced it either to ipfiltering or cable modem (both likely candidates). Do you get all the proper lights on both your NIC and the cable modem? Yes on dc0 I do, however I not familiar with the other two 3COM XL txp0, txp1.

An acceptable resolution is VESA_800x600 (I do not think that the kernel can do more at the moment?). To enable it you have to recompile your kernel with option SC_PIXEL_MODE enabled (so you can use the raster text mode). Then load the vesa support with kldload vesa and try vidconrtol -g 100x37 VESA_800x600. If it is o.k. for you put in your /etc/rc.conf file: allscreens_flags=-g 100x37 VESA_800x600 and add to /boot/loader.conf: vesa_load=YES to load the vesa module at startup.

DHCP and rc Questions For FreeBSD 4.10???
Hi All, I have installed FreeBSD 4.10 to serve as a headless gateway/router/firewall/NAT. The first problem that I have run into can probably be resolved easily. I tried to configure my NIC card via sysinstaller. However, rc.conf does not have a startup variable for dc0. Therefore dhclient is inoperable. I built this box to be headless therefore it is low-tech with no floppy or flash drive and is currently a stand-alone machine so I am not able to copy the rc.conf file to this post. dc0 is working because I can bring its status to active manually: '[EMAIL PROTECTED] ifconfig dc0 ether up'. I was wondering what what variables should be assigned to rc.conf, the related variables I have thus far are: ## ifconfig_dc0=dhcp dhcp_program=/sbin/dhclient dhcp_flags= ## It would be appreciated if someone could attach or copy an rc.conf file for a similar system configuration.

Re: DHCP and rc Questions For FreeBSD 4.10???
Hi All,
I've been researching this issue although it may be minor I don't like to rely on the
[EMAIL PROTECTED] unless I have to. I'm sure you understand...anyway,
http:www.freebsddiary.com has a tutorial that with info I could not find in The
Complete FreeBSD or Absolute BSD. It described two entries; one in dhclient.conf
and the other in rc.conf. See Below:
###
dhclient.conf
###
interface dc0{
send host-name redgate;
request subnet-mask, broadcast-address, routers, domain-name-servers, domain-name,
time-servers;
require domain-name-servers;
###
rc.conf
###
ifconfig_dc0=DHCP #IS THIS VARIABLE DECLARATION CASE SENSITIVE???
hostname=redgate
###
The question I have now is if this is all I have to do to get dhcp running at startup?
I anyone else has any suggestions they are welcome. Unfortunately I cannot test this
until the evening so feedback will be very helpful and will save me some time
researching. Thanks in advance.

Wrap your likes around 72 characters.
All you need in /etc/rc.conf is:
network_interfaces=lo0 dc0
ifconfig_dc0=DHCP
Everything else you added is just re-affirming the default values.

Questions on IPFW???
Hey guys, Question, when NAT overloading is it possible to use only IPFW rules to pass TCP/UDP packects to remote ip addresses within the network? Or do you have to use natd...because IPFW allows you to execute the following for example: ip from 192.168.99.100 80 to 192.168.99.101 9981 or even in conjunction with a dummynet rule of somesort?

Re: Questions on IPFW???
Hello Chuck, I was wondering if someone could help me answer some questions I have concerning IPFW vs. natd I am trying to allow my FreeBSD 4.10 gateway to perform port forwarding for SSH, SQL*Net and Webservice (Web not as important yet). I wanted to know if I can use IPFW as opposed to natd to redirect or pass TCP UDP (is ICMP out of the question???) to a remote location. Gateway::192.0.0.1:22 -- remote server 192.0.0.5:22 or 192.0.0.5:9881 for instance. From the configuration of ipfw it appears that it can be done instead of using natd. Any suggestions or corrections of my logic welcome. Thanks in advance. HZS -Original Message- From: Chuck Swiger [EMAIL PROTECTED] Sent: Aug 3, 2004 12:40 PM To: Hakim Z.

In particular, the destination address remains unmodified, so packets forwarded to another system will usually be rejected by that system unless there is a matching rule on that system to capture them. For packets forwarded locally, the local address of the socket will be set to the original destination address of the packet. This makes the netstat(1) entry look rather weird but is intended for use with transparent proxy servers. Or do you have to use natd...because IPFW allows you to execute the following for example: ip from 192.168.99.100 80 to 192.168.99.101 9981 That's the body of an IPFW rule which matches packets with those attributes. Without an action (allow, deny, fwd), what you've written isn't a complete rule: it doesn't mean anything by itself. or even in conjunction with a dummynet rule of somesort? Um. Do you understand the question you are asking? I don't-- perhaps try using a complete sentence. Better yet, why don't you tell us what your network looks like and what you want to do.

Re: Questions on IPFW???
Actually Chuck, You answered my question, I wanted to know which was better to use with port forwarding (ipfw or natd) and based on what you wrote, natd is a better fit due to the fact that I would not have to force the other machine to accept packets redirected from the NAT box using natd. Is that correct??? -Original Message- From: Hakim Z. Singhji [EMAIL PROTECTED] Sent: Aug 3, 2004 12:49 PM To: Chuck Swiger [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Questions on IPFW???

Is that correct??? That's right. Most people want to use NAT, because it lets you set up an internal network without having to specially configure the internal machines. With regard to your other question, if you want an external connection to, say, port 22 to be forwarded to port 22 on some machine on your internal network, use: redirect_port tcp 192.0.0.5:22 22 ...in /etc/natd.conf or your natd_flags in /etc/rc.conf. -- -Chuck ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

hi,
I`m trying to put up ipfw to work in my computer. I followed the directions
in placing the lines in the kernel:
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_DEFAULT_TO ACCEPT
now i have tried removing or simply commenting the default to accept
line, since what i want is to deny all.
now when running # make buildkernel (...)
i get errors like this:
/TMP/ccX10334.s : 2462 : ERROR : subtraction of two symbols in different
sections Idle PTD {. data section} - KERNBASE {*UND* section} at file
address 1554
this is one of many similar error lines that appear (with some different
numbers and file addresses)
and at the end I get a :
***Error Code 1
stop in /usr/obj/usr/src/sys/GENERIC.
***Error Code 1
stop in /usr/src.
***Error code 1
stop in /usr/src.
please, i looked for this and couldn`t find a solution.
i appreciate your help
