rivediamo tutta la configurazione:

dal server:

[code]# cat /etc/xinetd.d/sane

cat /etc/sane.d/saned.conf

cat /etc/sane.d/net.conf

systemctl status xinetd.service

netstat -nap|grep 6566

scanimage -L

cat /etc/sane.d/dll.conf|grep net

[/code]

dal client :

[code]# rpm -qa|grep sane

cat /etc/sane.d/net.conf

service sane-port
{
disable = no
port = 6566
socket_type = stream
protocol = tcp
wait = no
user = root
passenv = PATH
server = /usr/sbin/saned
}
[/code]

[code]# cat /etc/sane.d/saned.conf

saned.conf

Configuration for the saned daemon

Daemon options

Port range for the data connection. Choose a range inside [1024 - 65535].

Avoid specifying too large a range, for performance reasons.

ONLY use this if your saned server is sitting behind a firewall. If your

firewall is a Linux machine, we strongly recommend using the

Netfilter nf_conntrack_sane connection tracking module instead.

data_portrange = 10000 - 10100

Access list

A list of host names, IP addresses or IP subnets (CIDR notation) that

are permitted to use local SANE devices. IPv6 addresses must be enclosed

in brackets, and should always be specified in their compressed form.

The hostname matching is not case-sensitive.

#scan-client.somedomain.firm
#192.168.0.1
#192.168.0.1/29
#[2001:7a8:185e::42:12]
#[2001:7a8:185e::42:12]/64

NOTE: /etc/inetd.conf (or /etc/xinetd.conf) and

/etc/services must also be properly configured to start

the saned daemon as documented in saned(8), services(4)

and inetd.conf(4) (or xinetd.conf(5)).

[/code]

[code]# cat /etc/sane.d/net.conf

This is the net backend config file.

net backend options

Timeout for the initial connection to saned. This will prevent the backend

from blocking for several minutes trying to connect to an unresponsive

saned host (network outage, host down, …). Value in seconds.

connect_timeout = 60

saned hosts

Each line names a host to attach to.

If you list “localhost” then your backends can be accessed either

directly or through the net backend. Going through the net backend

may be necessary to access devices that need special privileges.

localhost
