EagleDev:TailGunner

Hallo to all,
I'm "Tailgunner" and i'm Italian. i had a thread with baud123 and he encouraged me to open this page... if i can do something for someone, es. translate something english in italian, or doing some tests.. (i'm not a developer, but i know "something" about networks ...) well, tell me, my email is tailgunner75 at email _n0_sPam_dot it )

Testing 2.0.0 driver version

I installed the new 2.0.0 version, on a MDK 9.0 (i know, it's old, but i'm using 2.4.27 kernel ) and it has fixed mss-mtu problems (see above) however, i wasn't able to get syncro with *.bnm files included in package, and i had to use the 1.9.8's bnm files to create a "new" dsp code image to use. I tried cvs version, but haven't tried the rc1 release (should try it?)

here are the 2.0.0 bnm's md5sum output (those that doesn't work)

and there are the 1.9.8 bnm's md5sum output ( those that works....)

i've updated the eaglediag output too (see above) --TailGunner 13102004

mmmh i've reinstalled cvs version after renaming /etc/eagle-usb directory...... and now all works (with new bnm files....) now i don't know why, but i think that the cvs installation didn't overwrote the existing eagle-usb.conf file (?????) in fact when i edited this file, i found the old OPTXX values..... then i restored both eagle-usb.conf and dsp_code_pots.bin and reset modem, and it got syncro..... then i uninstalled driver, moved /etc/eagle-usb directory to /etc/eagle-usb.old and reinstalled driver..... and it works again... could be a install script bug? when upgrade, i am very careful to uninstall (make uninstall) old drivers when asked (and i noted that script always ask me to run make uninstall, even if i already did it). --TailGunner 13102004

Now i'm testing for dsp autoload, when i unplug-replug the modem, hotplug doesn't load automatically the dspcode, and i must send eaglectrl -d command.... the automatic connection at startup ("service" eagle-usb) also don't work and now i want to see if it depend by hotplug, (my system) or by script.... --TailGunner 13102004

IPV6 6to4 testing

hallo at all, i'm testing the ipv6 protocol, using a 6to4 tunnel. I set up the tunnel and the ipv6 network, and tried to configure ipv6to4 in two modes:

1) 	6to4pubgw --- internet --- firewall/nat ----- 6to4gw----ipv6net 
	|  (IPv6)  |           (IPv4(IPv6))            |         (IPv6)        |

in this case the firewall (on which is installed the modem) does not handles the ipv6 packets. When a client sends a request to a ipv6 public server, sends it to the 6to4's internal ipv6 address, which incapsulates the packet in a ipv4 (tunnel), and then forward it to the firewall's internal ipv4 address. The firewall then forward the packet (after nat) to the public 6to4 gateway....

2)        6to4pubgw --- internet --- firewall/6to4gw----ipv6net    
          |   (IPv6)  |    (IPv4(IPv6)) |         (IPv6)                 |

in this case the firewall handles both ipv6 and ipv4 stacks, when a client needs to communicate using ipv6, sends the request to the firewall's internal ipv6 address, the firewall then encapsulates the ipv6 packet in a ipv4 packet and send in to the 6to4 public gateway....

it works in both configurations, but i'm not able to surf on some sites..... having a look in the firewall's log, i saw error "[Eagle-usb] Discarding message (pdu 1502 > mru 1498)" again (the same error i had at the beginning....). it's a mss-mtu problem, and affects only tcp connections. on ipv4 i worked around that using the TCPMSS netfilter target, but TCPMSS does no exist (yet) for ipv6. I've read about Robert.Siemer's patch ( PPPdPatch page ) and i think that it should definitively fix the problem.... i'd like to know others opinions about that.... i'm using 1.9.8 driver version, but i'm just upgrading, (already recompiled kernel (2.4.27) and waiting for 2.0 release .... i haven't found tarball yet.... )
thank you, -- TailGunner 12102004

can be found on this page EagleUsb200 as a rc1 but see FeedBack200 (for the moment, there are small corrections that need to be applied for it to compile on 2.4.x) -- BenoitAudouard 20041012

The 2.0.0 driver version seems to have fixed this, now i'm able to receive big sized packets, (1516 instead of 1512) without errors, and anything works fine.... i removed the tcpmss iptables rules, set ppp0 mtu to 1500 and disabled tranparent proxy, and all works.... great!! --TailGunner 13102004

kernel panic

Fixed. Probably an hardware problem...

Netdev Watchdog problem

seems fixed by 1.9.6 version

Samba Configuration

In this section i've explained what i did to prevent Samba by sending broadcasts on modem's virtual interface

Edit the main samba configuration file smb.conf, generally it's locatated in /etc/smb.conf or /etc/samba/smb.conf. In section "global" add (or locate) parameter "interfaces" and specify on which interfaces samba will be active, for example:

interfaces = 192.168.3.5/24 127.0.0.1/8 (ip+mask) or interfaces = eth0 eth1 lo (interface name)

then, always in section "global" add (or locate) parameter "bind interfaces only" and set it to yes

bind interfaces only = yes

this force samba to use only the interfaces listed in "interfaces" parameter. Note that if you use this parameter, you must specify the loopback (lo) interface in interface list, otherwise smbpasswd and swat will not works properly.

here is a netstat output for samba service that show on which interface the samba daemons are listening after modified smb.conf

netstat -apn | grep smbd

tcp 0 0 192.168.x.x:139 0.0.0.0:* LISTEN 4515/smbd
tcp 0 0 127.0.0.1:139 0.0.0.0:* LISTEN 4515/smbd

netstat -apn | grep smbd

udp 0 0 192.168.x.x:137 0.0.0.0:* 4519/nmbd
udp 0 0 0.0.0.0:137 0.0.0.0:* 4519/nmbd
udp 0 0 192.168.x.x:138 0.0.0.0:* 4519/nmbd
udp 0 0 0.0.0.0:138 0.0.0.0:* 4519/nmbd

this is that i did, it should be sufficient to prevent samba by sending broadcasts on all interfaces. The nmbd daemon still listen on all interfaces (0.0.0.0) but it should only listen for incoming broadcasts, and send broadcasts only on specified interface.

Eaglediag output

here is a new eaglediag -a output
