[Eciadsl-devel] 1.45 test report

[Pekka S. <pek...@ko...>]

Eci kernel module driver

Tested version: 1.45

Test enviroment:
Duron 650MHz
Linux 2.4.18
Linux-ATM 2.4.0

ADSL Line: RFC1483/Routed/LLC speed 512/256

Test duration: 3h 15min

Tested programs and protocols:
ftp, http, ssh, pop3, smtp, ping, ping flood, nmap, opera, netscape, tcp, udp, icmp

Test flow frame:

Line open at 17:34
icmp
pop3
smtp
ssh
ftp upload
ftp download
ftp download
ping flood
nmap
http
Box hang totally at 20:49 during web surfing with opera.

Test flow:

icmp
ping with normal packet size and interval, 50 packets sent. 1% packet loss.

pop3
Recieved email from pop3 server just fine.

smtp
Sent email through smtp server just fine.

ssh
1 ssh connection work just fine.
2 simultanous ssh connections work just fine.

ftp upload
Uploaded small ascii file to ftp server. works just fine.

ftp download
downloaded 30Mb file. transfer speed 52k/s. works just fine.
estimate cpu load during download 2.08 !!!
douplechecked ftp download with 4Mb file. works just fine.

ping flood
ping -f host at internet, 15% packet loss.

nmap
tcp scanned host at internet, real slow scanning. scan aborted due low speed.
nmap work only with -P0 option enabled. If -P0 was not set I got following error:
FATAL: Unknown datalink type (19) Caplen: 0; packet

http
Web surfing is real slow with eci. http requests takes real long time, even with known highspeed servers. Connecting to server takes real long time. After http request and connection is made, data from server comes in just fine. This is douplecheked with netscape and opera, many times.

Box hang
System hang totally during web surfing with opera. No syslog entry or oops about hang. Yesterday I was also testing 1.45 version and also during that 1h test my box hang totally with web surfing with netscape. opera caused 3 oops while eci was loaded and used...


Conclusion

Eci kernel module driver is not ready or really usable yet. Driver developement should still stay on beta stage. Speed optimation is needed and totals system hangs must be solved out as oops with other running programs while eci module is loaded.


Syslog messages about this test session is available by request.
