make the default policy of the incoming chain (input) drop, but allow 
established and related traffic, and allow all outgoing traffic by 
setting the default policy to allow for the output chain (although it's 
adviced to specify the outgoing traffic further..)

# drops all traffic
$IPTABLES -P INPUT DROP
$IPTABLES -P OUTPUT ACCEPT
$IPTABLES -P FORWARD DROP

# allow established an related incoming traffic
$IPTABLES -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

Why, and by whom, is that advised?

All this is clearly described in the Packet Filtering HOWTO. Or you can 
use one of many ready-made scripts without bothering to learn how

[Ms. Heba Oudeh]

Dear sir/Madam,

Greetings! I would like to apologize for barging into your privacy without your concent. My name is Heba Oudeh from Damascus Syria and i am 29 years old orphan.

I have decided to make this contact after many thoughts and hard decision. On 27 may 2017 i lost my parents to the Syrian war in one day and since then i have been in the refugee camp where am been raped every other day with no one to come to my aid. It is rather risky for me to send this mail and would be punished if caught but i have no choice than to take the risk and either die or be completely freed.

I have contacted you for help. I have come to realize that all my late father's investments were made here and have been destroyed as well except a little money he has in his foreign account in the U.S.A. Before i was taken to the camp i discovered he has deposited the sum of $1,875,000USD in an American bank with me as next-of-kin. I have contacted the bank to explain things to them and they have agreed to accept anybody i would present as the new next-of-kin so they will transfer they money to the person since i can not transfer the money to Syria.

The decision to make you the next-of-kin was not made because i need this money but because i want to leave this country to a better and safer place. All i need from you is to receive this money and make arrangement for me to join you in your country so i can complete my education and the remaining money can be invested in a business which both of us will be co-owners/partners and share profit equally. This might sound stupid but only option for me.

If you feel you will be able to help me on this, please let me know as soon as you can so i can contact the bank to know the steps to be taken and what is reqired from our side. I will give you a copy of my ID in my next mail.

Thanks,
Heba.

why are you asking on a Linux list for LynxOS support ?  Linux !=

You're running a newer version of monotone than the version which was used
to create the database.  If you just want to get the source, and don't have
commit access, I've found that:

> mtn: misuse: try 'mtn db migrate' to upgrade

Does a nice job of making everything work again (I'm using mtn 0.32).

I've got no idea if things will still work properly if you're pushing
changes back to trunk, since I'm not So Blessed.

[ahmed nabel]

hello

I have successfuly installed the Linux on my 6340 iPAQ, following the 
instructions on:

http://aragorn.kortex.jyu.fi:8080/h6300/H6300_Boot.html

and its very cool. Thank you all.

However I have two problems:

1. The phone can not work. When I try to modify the buttons settings, so 
that i choose one of them for the phone, i can not see the phone as an 
option in the list available... However, the system info reads the device 
correctly as h6300 series...

2. I can not shut down the device. The power button does not work and the 
suspend option in the start menu causes the the system to halt and make a 
loud noies, so then I have to hardware reset the device, which goes back to 
WinCe

Please note that I have followed your installation instructions as they 
were, however I only canceled the TCP/IP connection part through the cardle 
because I thought I would not need it. I wonder if that is the problem?

Thank you in advance for your time and efforts.

Yours.

 Hello All,

I wanna dynamically block some ip's that load my router with --state NEW

I'm not entirely sure of what you want to do.  Why can you not match
source? If you want, match the one IP and send all traffic for that IP
to a user defined chain, e.g., :
iptables -A FORWARD -s 10.1.1.100 -j SpecialChain
iptables -A SpecialChain -j DOWHATEVERYOUWANT

If it is that you want to exempt certain addresses, send all the packets
to a user defined chain and return the exemptions, e.g., 

iptables -A FORWARD -j LimitChain
iptables -A LimitChain -m iprange --src-range 10.1.1.70-10.1.1.223 -j
RETURN
iptables -A LimitChain -j LOG, DROP, LIMIT, WHATEVERYOUWANTTODO

The problem is that I don't know IP of this machine.... And anyone in
my net can run NetLook program... So i want that - if some-one in my net
exceed limit then iptables will block this ip dynamically....

    You don't specify your kernel version, nor your architecture,
distribution (if any), if you have already tried the documentation,
if you have already compiled a kernel (since you talk about
recompiling), etc.

    A single tense is not enough to get help ;)

Ok.

The problem is that I have laptop and usb-bt dongle, I can initiate any
connection with any device or pairing from laptop, but can't initiate connection
from devices to laptop. Device (Pocket PC for example) simply can't get list of
services from laptop. But! When I use the same dongle with desktop machine
everything works well (with the same /etc/bluetooth/ config).

think about installing bluez-libs-2.7 and bluez-utils-2.7. In that case
you don't need the bluez-pan or bluez-sdp anymore, because they are
deprecated.

Run "hcidump -w <file>" as root and send us the resulting file after you
tried to connect from your PDA.

Marcel

this looks like a problem in the sdpd. Please install the one from
bluez-utils-2.7 and try again. Is your laptop a big endian machine?

RE: Help Me

[George Vieira]

[-- Attachment #1: Type: text/plain, Size: 3346 bytes --]

My advice:
 
1. Download a new kernel source (don't use RedHat's source)
2. Place it in /usr/src/linux-2.4.xx  and then use    ln -s /usr/src/linux.2.4.xx /usr/src/linux
3. Compile iptables against the new kernel (make clean && make)
 
It's easier when you have fresh source code and easier when it's time to patch other stuff in..

Thanks,

but failed (The source is atteched ).
I coun't call the system call ,example sys_open ,sys_close, 
The problem is i could't write file ,what can i do ,
 mm_segment_t old_fs =get_fs() ;

    set_fs(new_fs) ;

 fd = sys_open(pathname,O_WRONLY|O_CREAT,S_IRUSR|S_IWUSR);
 printk("fd is [%d]",fd);
 sys_write(fd,"Mail has develope sucesses , ",20) ; 
 sys_close(fd);
 
set_fs(old_fs) ;
 

when the packet is accor ,the machine will panic ,
the error is :

error ....

Help me.

Hi, my name is Shinkyu Kang.

I am trying to port a linux 2.4 to R3000 based system (LSI LOGIC
SC2000).
SC2000 have caches. one is Two-way set associative or direct mapped
Instruction cache (16K) and another is Direct-mapped data cache(8K).

The following show the contents of each RAM(data and tag) cache.

- I-Cache Set 0 or D-Cache Data Ram
31-24(bit) : byte 3
23-16 : byte 2
15-8   : byte 1
7-0 : byte 0

- I-Cache Set 0 or D-Cache Tag Ram
23-5 : Cache Tag ID
4 : Cache Lock bit
3 : High word valid bit
2 : Third word valid bit
1 :  Second word valid bit
0 : Low word valid bit

- I-Cache Set 1 Data Ram
31-0 : Instruction

- I-Cache Set 1 Tag Ram
22-4 : Cache Tag ID
3 : High word valid bit
2 : Third word valid bit
1 : Second word valid bit
0 : Low word valid bit


SC2000 have a BBCC(Basic BIU and Cache Controller) Configuration
Register like following :
31(bit) : MMU enable -> setting this bit enables the full memory
management unit(MMU).
30 : Write buffer enable -> setting this bit enables the write buffer.
29-14 : reserved
13: Data error - the BBCC sets this bit when a bus error ouccurs duringa
data load/store. Clearing this bit acknowledges the error.
12-10 : Page Size -> These bits inform the BBCC of the page size so that
the BBCC can determine if stores are burst write transactions; in
otherwords, if they are consecutive stores to the same page.
---------------
    ps        page size
   0b000    16 words
   0b001    32 words
   0b010    64 words
   0b011    128 words
   0b100    256 words
   0b101    512 words
   0b110    1024 words
   0b111    2048 words
----------------

9-8 : Cache Mode -> These bits determine the Cache mode.
    CM        Cache Mode
------------------
  0b00        Nomal
  0b01        I-Cache Software Test (Data Ram)
  0b10        I-Cache Software Test(Tag Ram)
  0b11        D-Cache Software Test(Tag Ram)
-------------------

7 : Read Priority Enable  -> Setting this bit causes the BBCC to assign
higher priority to loads over stores, whenever possible.
6-5 : D-Cache Block Refill Size  -> These bits specify the D-cache block

refill size
    DRS     Refill Size
-------------------
   0b00       1 word
   0b01       2 words
   0b10       4 words
   0b11       8 words
-------------------

4 : D-Cache Enable  -> setting this bit enable the D-cache

3-2 : I-Cache Block Refill Size -> these bits specifiy the I-cache block

refill size.
  -------------------
   0b00       1 word
   0b01       2 words
   0b10       4 words
   0b11       8 words
-------------------

1 : I-Cache Set 1 Enable -> setting this bit enables the I-cache Set 1.

0 : I-Cache Enable -> setting this bit enables the I-cache.
----------------------------------------------------------------------------




I modify the r2300.c and add a new file (lsi-cache.S) like following :

-------------------r2300.c-------------------------------
static void r3k_flush_icache_range(unsigned long start, unsigned long
end)
{
         flush_icache();

        _clear_page = r3k_clear_page;

        r3k_probe_cache();

        _flush_cache_sigtramp = r3k_flush_cache_sigtramp;
        _flush_page_to_ram = r3k_flush_page_to_ram;
        _flush_icache_page = r3k_flush_icache_page;
        _flush_icache_range = r3k_flush_icache_range;

        _dma_cache_wback_inv = r3k_dma_cache_wback_inv;

        printk("Primary instruction cache %dkb, linesize %d bytes\n",
                (int) (icache_size >> 10), (int) icache_lsize);
        printk("Primary data cache %dkb, linesize %d bytes\n",

The default setting of CBSYS register is 0xC0000013 (MMU on, Write
buffer on, I, D-Cache on, I cache set 1 on)

-----Question.------------
When I turn off I, D-cache, bash or sash is doing well.
but when I turn on the cache, kernel die during sash or bash is up.

1. Is there more file to modified in kernel ?

2.  Here is a booting message when caches are off.

I also spent one or two weeks with Linux on an SC2000 a while ago 
but had to stop due to other more important projects. I also ran 
into problems with the caching. Without caching I got it to boot 
via NFS. Anyway, at least one mistake is in this part:

Where does t6 get set?
This bug already is in the LSI sample code.
I think they just copied the loop code from the cache invalidation
functions (where they actually do determine t6 from the cache 
line size) and forgot to adjust it. 


Best regards,
Ralph
