[sane-devel] net backend out of service

[Wolfram Heider]

Recently the net backend is on strike with me. I am here in a minor  
network with a few machines running under Opensuse 11.1/11.2 (32 bit/64  
bit) and additionally some virtual machines. SANE versions are 1.0.19,  
1.0.20 and latest unstable version (20100303). Two machines are scanning  
servers. And it's always the same, when trying to connect to one of it  
nothing happens.

A telnet saneserver 6566 gives back a "Connection closed by foreign host"

The interesting part of SANE_DEBUG_NET=128 is:

[net] connect_dev: trying to connect to xxx.xxx.xxx.xxx
[net] connect_dev: [0] connection succeeded (IPv4)
[net] connect_dev: sanei_w_init
[net] connect_dev: net_init (user=ich, local version=1.0.3)
[net] connect_dev: argument marshalling error (Connection reset by peer)
[net] connect_dev: closing connection to xxx.xxx.xxx.xxx

and:

[net] connect_dev: trying to connect to localhost
[net] connect_dev: [0] connection succeeded (IPv4)
[net] connect_dev: sanei_w_init
[net] connect_dev: net_init (user=ich, local version=1.0.3)
[net] connect_dev: freeing init reply (status=Success, remote  
version=1.0.3)
[net] connect_dev: done

so the server machine itself is able to connect via the net backend to the  
attached scanner

I wonder if somebody has a clue what's going on here. Any hints are  
welcome.
