When statically linked Abort trap: 6 (core dumped)
Hi all This is FreeBSD 9.1 on i386. My program works well without any issue when all libraries are dynamically linked.

ipfw+natd port forward does not work as intended
Hi all
I'm on 192.168.1.62, the server running on 192.168.1.3 and listen to port 1234.
I want any connection going out of my machine to port 1234 to port forward to
192.168.1.3:1234.
But when I attempt to connect to 192.168.1.1:1234 , natd shows following
verbose message:

My laptop and the server are in two different countries. Btw, laptop also run
FreeBSD.
>2) check server is accessible (ping from laptop)
Yes, the server is accessible (ping from the laptop.
>3) check server is accessible via TCP/53 ("telnet 53" from
>your laptop)
No, there was a reverse DNS error here. It was pointing to the Reverse DNS
server of the data centre.
Now its been corrected:
telnet 53
Trying ...
Connected to ns1.mydomain.com.
Escape character is '^]'.
>4) check firewall on server and/or devices between server and laptop, it may
>block requests
No firewall on the server yet.
>5) check your server is configured to use the same DNS: cat /etc/resolv.conf
>
nameserver 127.0.0.1
nameserver other_ip1
nameserver other_ip2
Although the Reverse DNS is now been corrected, still cannot ping as from the
laptop:
ping www.mydomain.com
ping: cannot resolve www.mydomain.com: Host name lookup failure
Any ideas?

Bind99 stopped resolving for external queries
Hi all I'm running a FreeBSD 9.0-RELEASE based server. It used to work fine. But suddenly about 2 days ago stopped resolving DNS for external queries. >From my laptop if I ping the server: ping www.mydoamin.com ping: cannot resolve www.mydoamin.com: Host name lookup failure But if I log in to the server and do the same ping, it works fine. As a fix, I have upgraded the Bind99 to the latest bind99-base-9.9.2, but it did not fix the issue. I don't see anything changed in my DNS server setup. Appreciate very much if any help could be extended in this regard to understand what went wrong in the server. Many thanks in advance.

My this FreeBSD 9.0 box is seems very messy. I have another issue that getaddrinfo(3) doesn't accept "localhost". After installing FreeBSD 9.0, I installed KDE, then realised that the existing Intel display driver does not support my Intel Sandy Bridge based GPU. So I had to patch the kernel to support KMS based latest Intel driver, upgraded to Xorg to 7.5.2, etc. etc. Whole process was done multiple times as I was new to this complex upgrade. I presume, I should erase off the hard disk and reinstall everything cleanly and then retry my programs on FreeBSD 9.0. If the problem still persists, I'll surely do a detailed debug. Pls note, whole thing works well on FreeBSD 8.1. As this is time consuming and as per existing commitments, I only try this at least in another two weeks time. I will sure let the list know the outcome.

Following code fragment works in FreeBSD 8.1-RELEASE, but not in FreeBSD

if (error)

fprintf(stderr,"getaddrinfo failed - %s\n", gai_strerror(error));
exit(1);
}
It complains: getaddrinfo failed - hostname nor servname provided, or not known

Hi all I'm developing an multi-threaded application on FreeBSD. When it is running for sometime, it develops a Segmentation fault. The ddd debugger shows following: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 296c6580 (LWP 100137)] 0x28ee390e in _malloc_prefork () from /lib/libc.so.7 How could I know the exact line in source where this issue develops? Many thanks in advance.

How to sync a file on FreeBSD?
Hi all How to sync a file on FreeBSD (esp. on 8.1) to disk? I used fsync(2), but does not immediately flush to disk.

It does offer a TCP mode. Hi Damien and Chuck Appreciate for replying on this. I want to ask from the client, eg. where do you want to go?, If north, I want to forward to the north server, if south, to the south server. I need to get developed something probably similar to the Proto Balance (http://www.protonet.co.za/whitepaper.html). It says "connections are transparently forwarded to an instance chosen by Proto Balance". I want my daemon to make that choice.

Transparent load balancing
Hi all I need to implement a transparent load balancing daemon in C. That is, the daemon accept a TCP connection, get more info from the client, and forward the communication transparently to another server to handle it. How this could be implemented on FreeBSD?

Is KDE 4.4.5 on FreeBSD 8.1 this bad?
Hi all I have installed KDE 4.4.5 from ports (ie. with full compilation) on FreeBSD 8.1 on i386. Once HAL and DBUS is enabled in /etc/rc.conf, behaviour of KDE is surprisingly poor: 1. None of the desktop icons works to launch programs. Eg. Click or double click on Firefox icon does not launch Firefox. I have to right click on the desktop and click on "Run Command" and type firefox to run. 2. Once type firefox on the "Run Command" it doesn't appear until I shake the mouse! Once press enter, it doesn't run firefox till I shake the mouse again. The firefox comes in stages and every stage I have to shake the mouse to continue. Do others experience the same with KDE 4.4.5?

Is Mobile Intel HM57 Express chipset compatible with FreeBSD?
Hi all I'm planing to buy a Dell Vostro laptop which comes with a Mobile Intel HM57 Express chipset. Could I know from the list, is FreeBSD either 7.2 or 7.3 compatible with the above chipset? Above laptop comes with Nvidia Geforce 310M graphics chipset and I plan to install KDE 4.4 too, could I get a graphical desktop running FreeBSD 7 series? Many thanks in advance.

How to print using cups on FreeBSD?
Hi I'm trying to print using cups 1.3.10 on FreeBSD 7.2 on a Epson Stylus Photo R800 printer. It prints garbage! That is, it print some series of characters. My first question is, does cups work on FreeBSD to print? Here is my side information: pkg_info | grep cups cups-base-1.3.10_4 Common UNIX Printing System: Server cups-client-1.3.10_4 Common UNIX Printing System: Library cups cups-image-1.3.10_4 Common UNIX Printing System: Library cupsimage cups-pstoraster-8.15.4_4 Postscript interpreter for CUPS printing to non-PS printers gutenprint-cups-5.1.7_4 GutenPrint Printer Driver pkg_info | grep foomatic foomatic-db-20090530 Foomatic database foomatic-db-engine-4.0.1,2 Foomatic database engine gutenprint-foomatic-5.1.7_2 GutenPrint Printer Driver I have followed this for cups configuration: http://www.freebsd.org/doc/en/articles/cups/printing-cups-configuring-server.html ls -l /dev/unlpt0 crw-rw 1 root cups0, 155 Nov 26 12:23 /dev/unlpt0 ls -l /dev/ulpt0 crw-rw 1 root cups0, 154 Nov 26 12:23 /dev/ulpt0 I don't have /dev/lpt* . I'm a member of cups group. I'm using KDE 3.5.10. I have used KDE printer manager to print a test page after setting up the printer. So what other configurations do I need to do on FreeBSD to get the printing working?

How to find real CPU temperature?
Hi all I'm running FreeBSD 7.2 on Intel P4 computer. The "lmmon -i" shows 21C and when go to BIOS shows 65C!

Thanks everybody for valuable replies. In fact, I also used readlink(2) but fed
the symlink path directly from dirent, which was partial, readlink(2) requires
full path.

How to modify the default unmount time of automounter (amd)?
Hi all
I'm using the amd that comes with the FreeBSD 7.2 i386.
I want to automatically mount and unmount an USB thumbdrive. Mounting part work
well, but the unmounting part does work as specified. I have set "utimeout=1"
but amd still take 120 seconds to automatically unmount.
cat /etc/rc.conf
amd_flags="-a /.amd_mnt -l syslog -x all /media /etc/amd.map"
amd_enable="YES"
cat /etc/amd.conf
[ global ]
map_type = file
[ /media ]
map_name = /etc/amd.map
cat /etc/amd.map
/defaults type:=host;fs:=${autodir}/${rhost}/host;rhost:=${key}
* opts:=rw,grpid,resvport,vers=3,proto=tcp,nosuid,nodev,utimeout=1
thumdrive type:=pcfs;opts:=longname;dev:=/dev/da0s1;fs:=${autodir}/thumdriv
I want to automatically unmount of 1 second of inactivity. Have I specified the
unmounting incorrectly?
Thanks in advance.

If you refer that I use bash for root is the problem, there is no difference by switching root's shell to sh. With sh as the shell for root: 1. Still cannot login as root from the console. Child process died error. 2. "su -l" doesn't work, child process died error. 3. su works. But the prompt is [...@host name]# Why it doesn't print r...@host? whoami shows root.

I have put some print messages to login.c and libutil/login_class.c source files. Here what it shows: login: pam_session_established, going to fork. login: Master process ID: 763 login: We are now in the child process! kernel: pid 868 (login), uid 0: exited on signal 11 login: Child process ID: 868 login: export_pam_environment() done. login: We're done with PAM now login: username: root login: setlogin() done login: lc: root login: pw_uid: 0 login: We are now inside setusercontext() What happens is, after the child process is forked in login, it die due to some reason. But the child process continue up to setusercontext(). That "We are now inside setusercontext()" is the first statement in the setusercontext(). It doesn't execute up to LOGIN_SETGROUP after that. But the strange thing is whole thing get executed well for normal users. The cron also fail due to same reason. Btw, regarding bash for root, I'm using that on other FreeBSD machines for long time.

Cannot login as root, exited on signal 11
Hi all This is FreeBSD 7.2 on i386. After a custom compiled from sources installation, root cannot log in but normal users can log in. Here are the messages in /var/log/messages: Jun 14 00:44:58 xxx login: ROOT LOGIN (root) ON ttyv0 Jun 14 00:44:58 xxx kernel: pid 757 (login), uid 0: exited on signal 11 Jun 14 00:45:00 xxx kernel: pid 760 (cron), uid 0: exited on signal 11 (core dumped) Note, cron also fails. When try to log in, it checks the password correctly, ie. if I type a wrong password for root, it says "Incorrect ...", but when type the correct password, it simply come out and prompts the login prompt. It looks like something is missing required for the root to log in. I'm using bash shell. Any ideas? Many thanks in advance.

I want to append all variables in X and Y into Z so that "echo $Z" should be:
XX1=YES XX2=YES YY1=YES YY2=YES
I'm doing everything in command line not using any scripts.

How to say this in Bash?
Dear all
This may be slightly OT, but I'm using on a FreeBSD machine. How to convert
following into bash style?
echo "${X}" > ${Z}
echo "${Y}" >> ${Z}

Graphviz port compilation error
Hi all This is FreeBSD 7.1 on i386.

I had a look at source code. The program flow seems to be is as follows:
shutdown => (signals) init => reboot() => boot() => shutdown_final =>
shutdown_halt() => cpu_halt()
I did not see which function is called to request a power down.
The __asm__ ("hlt") doesn't power down, isn't it?
Could you guys help me to identify how shutdown request a power down.
Many thanks in advance.

No pam_module.so found
Hi all I have built FreeBSD 7.0 with openpam (ver. 20071221) on (i386). Now I cannot login through the console, it gives following error message: login: in openpam_load_module(): no pam_self.so found login: pam_start(): system error But I can login remotely using ssh. In both cases I tried only root account. After ssh into the system, when I try to login as another user, it gives following error on the console: su -l test su: in openpam_load_module(): no pam_rootok.so found su: pam_start: system error All my pam modules reside in /usr/lib/ and the version number of pam modules match the version number of the libpam (/usr/lib/libpam.so.2). Eg. pam_self.so.2 and pam_rootok.so.2 are available in /usr/lib/. My first question is, is suffix 2 in this case, the Module Version number?

Hi, thanks for the reply. What if I'm a port developer? :) Inability to compile shows an error somewhere else. It looks like a wrong header files symptom.

This was indeed the case, worst yet, I was trying to free a part of the buffer
(as per your example above) by mistake which was not allocated by malloc.

This problem happens very early stage of my program. Its the very first free()
develops a problem.
I checked again, up to the this problematic free(), functions return newly
allocated strings properly:
char *f( )
{
char *newstr = NULL;
:
newstr = (char *) malloc(p - sp + 1);
if (newstr == NULL)
return NULL;
:
return newstr;
}
Can a yet not executed wrong free() elsewhere cause a problem of this nature?

Hi thank you very much for your reply and the test case.
That is, in a trivial case like this, free() works well. Hopefully free() works
well in all cases too.
But my main program is 1900 lines, f1() and f2() are in a 2200 lines second
file. The f1() and f2() calls some functions from a 500 lines third file. The
main program call another function, f3(), from 2nd file, pass pointers to two
functions f4(), f5() of main program. The while loop iterate more than one
million times. Its quite a complex situation.
There must be an error somewhere else. I noted free() causes lot of troubles.
It is easy to write complex programs if you just let to leak memory. But in my
case, since the program iterate millions of times, if I let to leak, I'm sure
it will run out of RAM.
So the question is, if you were to encounter this issue, how would you approach
it and find the culprit?
I'm using pretty basic tools to write complex programs. I use Kate to write
programs, Makefiles to compile, use GCC, and use ddd in case of a trouble.

Segmentation fault when free
Hi all
I'm running FreeBSD 7 on i386. I have a C program compiled with gcc 4.2.1
20070719.
Logically my program is:
char *a;
char *b;
char *c;
while (cond)
{
a = f1(); /* malloc() and send a string */
b = f2(); /* malloc() and send a string */
c = (char *) malloc(strlen(a) + strlen(b) + 1);
c[0] = '\0';
strcat(c, a);
strcat(c, b);
free(a);
free(b);
}
When it executes free(b), my program exits with Segmentation fault: 11. The
free(a) executes well.
The problem is with free(b). Even swap free(b) first and free(a) next, it still
crashes at free(b).
If I comment out free() lines, further down the program, first few characters
of one string get dropped when executes a completely unrelated line.
How could I bit more narrow down the problem?
Many thanks in advance.
Kind regards
Unga

Your statement prints the Surname but the variable $surname disappear after that and not available for further processing. I'm referring to two sources for this: 1. Learning the bash shell, 2nd Edition. O'Reilly publishers Where on page 170, under read section The basic syntax is: read var1 var2... This statement takes a line from the standard input and breaks it down into words delimited by any of the characters in the value of the environment variable IFS. The words are assigned to variables var1, var2, etc. 2. http://www.unix.com/shell-programming-scripting/29202-perl-like-split-function-bash.html It looks like it works for others but here on FreeBSD 7.0, bash 3.2.33(0)-release, I find it difficult to get this syntax to work. > Also, probably a typo - but you're assignment of string > in the first line > should omit the $ sign. > Yes, sure is a typo.

string split, bash and IFS
Hi all How to use bash and IFS to split a string? eg. $string = "Name:Surname:10" IFS=: echo "$string" | read name surname age This does not work for some reason. The read does not create name, surname and age variables. Any idea why? Appreciate your reply.
