The root is not so nice, but o.k. for testing. I myself use "nobody" and<br>
|
|||
|
|
have a setgid saned for minimum risk, but for a first test, root should be<br>
|
|||
|
|
o.k.<br>
|

|
|
<p>
|
|||
|

And I suppose you have sent SIGHUP to inetd, so it rereads its config -<br>
|
|||
|
|
right ?<br>

This is very weird. This sounds like the sane daemon failing very very early<br>
|
|||
|
|
or not connecting at all. Try straceing both sides of the connection.<br>
|
|||
|
|
The logs should give a clue on that.<br>
|
|||
|
|
<p>
|
|||
|
|
The daemon side might be a bit tricky, as it appears, when the connection is<br>
|
|||
|
|
made, started from inetd. There are two possible ways to get around this:<br>
|
|||
|
|
<p>
|
|||
|
|
1. Make a small script "ssaned", that looks like<br>
|
|||
|
|
#!/bin/bash<br>
|
|||
|
|
exec strace saned 2>/tmp/logfile<br>
|
|||
|
|
<p>
|
|||
|
|
2. use "strace -p [pid_of_inetd] -f" to attach to the inetd, and "-f"ollow<br>
|
|||
|
|
when it forks off the saned.<br>
