  1. 天文数据与归档培训 数据传输 何勃亮 国家天文台，中国虚拟天文台 hebl@nao.cas.cn

  2. SSH • sshuser@host -p port • .ssh/config • Host astrondata • Port 2013 • /etc/hosts • 192.168.40.28 astrondata • sshuser@host • ssh host • alias shost=‘ssh host’

  3. SSH Key • ssh-keygen -t rsa -C "your_email@example.com" • cat id_rsa.pub >> .ssh/authorized_keys • ssh 10.23.1.91

  4. scp • usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-iidentity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ... [[user@]host2:]file2 • Example • scp -P 2013 file user@astrondata:~/ • scp -P 2013 -r diruser@astrondata:~/

  5. rsync • rsync [OPTION]... SRC [SRC]... DEST

  6. rsync -e "ssh -p 2013" -azPsrchebl@host:dest • rsync -azP src host:dest 2>&1 > tsf_20131212.log

  7. 丽江2.4米望远镜 • 数据同化:抽取头信息,建立元数据表,除了普通的 FITS 头信息外,另外加入几个字 段 • filesize文件大小,精确到字节 • checksum 文件校验码,确认文件的完整性 • recdate入库时间 • 数据统计:统计此次数据的数目、大小等信息 • 数据入库 • 数据传输 • 发送归档报告
