+ | This relies on passwordless logins to a Secure Shell (ssh protocol). | ||

+ | |||
+ | Problems with no-password ssh login | ||
+ | |||
+ | Works: | ||
+ | |||
+ | Copy id_jn0805_rsa.pub and cat >> to authorized_keys2 in /home/dancing/.ssh on nsrv. | ||
+ | Created new id on dmach, added to authorized_keys2. OK | ||
+ | |||
+ | Seems to need file named id_rsa and authorized_keys2 on server. Other names | ||
+ | not useful unless used with -i (filename), which does NOT have to be in | ||
+ | .ssh. But seem to need some sort of concordance that is NOT clear in permissions | ||
+ | and users. | ||
+ | |||
+ | On dmach: | ||
+ | <code> | ||
+ | rsync -auv -e ssh dancing@macnash.telfer.uottawa.ca:/home/dancing/00_dancing dancing/</code> | ||
+ | will update files. | ||
+ | |||
+ | However, problems on eee701 with writing to vfat sd card. Managed fine with sshfs (once | ||
+ | set up ok). Also had trouble generating key, so copied key from eee901 id_rsa and | ||
+ | worked ok. | ||
+ | Seems to be need to remount (see remounter) | ||
+ | |||
+ | <code> | ||
+ | #!/bin/bash | ||
+ | # remount sd card /dev/sdb1 on /media/sd | ||
+ | sudo umount /dev/sdb1 | ||
+ | sudo mount -t vfat -o rw,noatime,dmask=0000,fmask=0000 /dev/sdb1 /media/sd</code> | ||
+ | |||
+ | BUT fmask and dmask likely not correct. | ||
+ | |||
+ | |||
+ | |||
+ | Does not work: | ||
+ | |||
+ | added user on Eee900 "dancing", | ||
+ | |||
+ | log in as dancing (from terminal) | ||
+ | |||
+ | ssh-keygen id_rsa etc. | ||
+ | |||
+ | sftp to nsrv dancing and upload pub key | ||
+ | |||
+ | ssh to cat to authorized_keys2 and chmod to 600. | ||
+ | |||
+ | No joy. | ||
