Hi, we're using amanda now for several years to back up our servers, but since a few days we have a strange problem with one of our hosts:
Amanda Backup Client Hosts Check -------------------------------- WARNING: cmso: selfcheck request timed out. Host down? Client check: 14 hosts checked in 30.960 seconds, 1 problem found. the log- and debug files on cmso look like: /var/log/messages: Mar 25 14:18:32 cmso amandad[1275]: error receiving message: Connection refused Mar 25 14:18:32 cmso inetd[402]: /usr/sbin/tcpd (pid 1275): exit status 1 Mar 25 14:18:41 cmso amandad[1282]: error receiving message: Connection refused Mar 25 14:18:41 cmso inetd[402]: /usr/sbin/tcpd (pid 1282): exit status 1 Mar 25 14:18:51 cmso amandad[1288]: error receiving message: Connection refused Mar 25 14:18:51 cmso inetd[402]: /usr/sbin/tcpd (pid 1288): exit status 1 /tmp/amanda/amandad.debug: amandad: debug 1 pid 2073 ruid 202 euid 202 start time Mon Mar 25 14:39:49 2002 amandad: version 2.4.1p1 amandad: build: VERSION="Amanda-2.4.1p1" amandad: BUILT_DATE="Wed Feb 28 18:49:15 CET 2001" amandad: BUILT_MACH="Linux cmso 2.2.14-5.0 #1 Tue Mar 7 21:07:39 EST 2000 i686 unknown" [...] got packet: -------- Amanda 2.4 REQ HANDLE 000-005E0508 SEQ 1017063743 SECURITY USER amanda SERVICE selfcheck OPTIONS ; GNUTAR md3 0 OPTIONS |;bsd-auth;compress-best;no-record;index;exclude-file=/etc/exclude.gtar; GNUTAR md2 0 OPTIONS |;bsd-auth;compress-best;no-record;index;exclude-file=/etc/exclude.gtar; GNUTAR md1 0 OPTIONS |;bsd-auth;compress-best;no-record;index;exclude-file=/etc/exclude.gtar; GNUTAR md0 0 OPTIONS |;bsd-auth;compress-best;no-record;index;exclude-file=/etc/exclude.gtar; -------- sending ack: ---- Amanda 2.4 ACK HANDLE 000-005E0508 SEQ 1017063743 ---- amandad: running service "/usr/local/amanda/libexec/selfcheck" amandad: error receiving message: Connection refused strage that the client gets a "Connection Refused" when receiving a message. During tests earlier this day I also got a message like "received malformed ACK" in the client's amandad.debug, but I can't reproduce this now. restarting the inetd doesn't help. unfortunately I can't reboot the machine right now. the tape server is located in the internal LAN behind a firewall doing NAT; the server to be backed up is located in the external LAN. this server also runs some rather heavy-weight JAVA application servers; the problem started when we installed another APPserver from HP (HP-AS). the HP-AS is not running now but the problem still persist. I guess that there's something wrong with the local ports, but I can't figure it out right now. OS is RedHat Linux 6.2, there are no local ipchains defined. Any ideas ? tnx in advance.
