问一个数据库异地备份的问题

Question

我使用的是postgres数据库～我想实现ftp自动备份～但是好象总是不行～请指教～下面是backup.sh代码

#!/bin/bash

FTPHOST=192.168.1.100

USER=postgres

PASSWD=111111

echo "Starting Backup PostgreSQL ... "

#big5 gb2312 gb18030

pg_dumpall > pgsql-backup.`date +%Y-%m-%d.%H:%M:%S`.dmp

tar zcvf pgsql-backup.`date +%Y-%m-%d-%H`.tar.gz *.dmp

echo "Upload File ..."

ftp -n ${FTPHOST} <<!

user ${USER} ${PASSWD}

binary

prompt

mkdir backup

cd backup

mput *.tar.gz

close

bye

!

echo "Remove temp file ..."

rm -rf pgsql-backup.*.dmp

rm -rf pgsql-backup.????-??-??-??.tar.gz

单独执行的时候就报这样的错
Starting Backup PostgreSQL ...
pg_dumpall: 无法与数据库 "template1" 联接: 致命错误:  没有用于主机 "[local]", 用户 "postgres", 数据库 "template1", SSL 关闭 的 pg_hba.conf 记录

pgsql-backup.2006-06-08.14:40:09.dmp
Upload File ...
'AUTH GSSAPI': command not understood
'AUTH KERBEROS_V4': command not understood
KERBEROS_V4 rejected as an authentication type
Interactive mode off.
Remove temp file ...
请问如何可以解决这样的问题啊～谢谢
