amindexd & java -> unexpected EOF/unprocessed input
Hello ;-)
I tried to connect to the amindexd service via Java. It is possible
to read what the Server first barfs out... but if I try to send
some commands (SECURITY root, HOST localhost, etc.) nothing happens
and the debug output of amindexd says, that there is an unexpected EOF
and some unprocessed input (the mentioned commands I sent before).
=
This is what the /tmp/amanda/amindexd.debug says:
< 220 kant AMANDA index server (2.4.1p1) ready.
? unexpected EOF
? unprocessed input:
-
? SECURITY root
-
amindexd: pid 5867 finish time Thu Feb 15 17:27:19 2001
=
I also tried to get a connection via Telnet, but the socket-port
of the telnet process is always to high, to be taken as a secure port
by the amindexd. Do you know a possibility of setting a portrange
to a telnet process?
Well, please have a look at the following (attached) tiny java program
and give me some hints, how to get a connection to the amindexd.
I want to write some interface from Java to amindexd for providing
a possibility for writing native java programs to take use of
the Amanda Backup Service ;-)
Please sent me a copy (CC:) to my private account ( mailto:[EMAIL PROTECTED])
thanx in advance,
Sebastian

amrecover: cannot connect to host (connection refused)
Hello,
I am using RedHat 7.0 with xinetd-2.1.8.9pre11-1.
amcheck and amdump are working properly, but if I want
to restore files from dump using amrecover, the tool
is not working.
Everything is called from the same host (localhost).
This is what the amrecover sends to stdout:
AMRECOVER Version 2.4.1p1. Contacting server on localhost ...
amrecover: Unexpected server end of file
And this is what I found in /var/log/messages:
Jan 29 07:51:51 myhost xinetd[1318]: xinetd Version 2.1.8.9pre11
started with
Jan 29 07:51:51 myhost xinetd[1318]: libwrap
Jan 29 07:51:51 myhost xinetd[1318]: options compiled in.
Jan 29 07:51:51 myhost xinetd[1318]: Started working: 8 available
services
Jan 29 07:51:54 myhost xinetd: xinetd startup succeeded
Jan 29 07:52:07 myhost xinetd[1318]: warning: can't get client
address: Invalid argument
Jan 29 07:52:07 myhost xinetd[1318]: file descriptor of service
amandaidx has been closed
Jan 29 07:52:07 myhost xinetd[1318]: select reported EBADF but no bad
file descriptors were found
I think, the problem is:
warning: can't get client address: Invalid argument
but do you know when this could happened?
This happens only the very first time, if I try to connect
via amrecover the next time, nothing happens in the syslog,
but the amrecover client barfs:
AMRECOVER Version 2.4.1p1. Contacting server on localhost ...
amrecover: Error connecting to server: Connection refused
It is possible for operator and root to do an rsh localhost .
The permissions for /root/.rhosts
-rw---1 root root25 Jan 28 23:44 /root/.rhosts
The permissions for /root/.amandahosts
-rw---1 operator disk 107 Jan 29 00:29 /root/.amandahosts
Amanda-User: operator
User Operator is in 'disk' group.
If you need the information of /etc/xinet.d/am*
I will attach these files. I tried to use the amanda inetd-entries
w/o tcp_wrappers, but the errors are still the same.
I will also put the debug output of /tmp/amanda to this mail.
So, I am not subscribed to the mailing list, please
do a CC to mailto:[EMAIL PROTECTED]
Any suggestions?
thanx in advance,
Sebastian
