Hello,
I want to switch from zfs send and receive with ssh todo it with netcat.
The send and receive process works without problems, but netcat won't work.
Server A is oi151a6-1
Server B is oi151a5-2
I use netcat with these commands:
Server A:
/root@oi151a6-1:~# zfs list -t snapshot
NAME USED AVAIL REFER MOUNTPOINT
...
tank/raid1-2@replication_09-09-12-19:40:00 0 - 16K -
tank/raid1-2@nc_test05 0 - 16K -/
Snapshot /tank/raid1-2@replication_09-09-12-19:40:00/ exists already on
Server B (received over ssh)
/root@oi151a6-1:~# ssh -n -f 192.168.10.201 "/usr/bin/nc -l -p 1337 |
/usr/sbin/zfs receive -F tank/raid1-2"/
With the previous command, I can see the netcat process on Server B:
/root@oi151a5-2:~# ps auxww | grep nc
root 838 0.0 0.1 2052 1380 pts/1 S 21:14:42 0:00 grep nc
root 805 0.0 0.2 3664 2384 ? S 21:14:14 0:00 bash -c /usr/bin/nc -l -p
1337 | /usr/sbin/zfs receive -F tank/raid1-2
root 806 0.0 0.1 2124 1144 ? S 21:14:14 0:00 /usr/bin/nc -l -p 1337/
On Server A:
/root@oi151a6-1:~# zfs send -I
tank/raid1-2@replication_09-09-12-19:40:00 tank/raid1-2@nc_test05 | nc
192.168.10.201 1337/
This exits with the following error:
cannot receive: failed to read from stream
This is only a testing server, so I enabled the user root and enabled
root login for sshd.
Can someone please help me with my problem? I never used netcat, so I am
a real beginner.
The funny thing is, when I issue the commands on the local servers, it
works without problems!
Server B:
/root@oi151a5-2:~# ///usr/bin/nc -l -p 1337 | /usr/sbin/zfs receive -F
tank/raid1-2
Server A:
//root@oi151a6-1:~# //zfs send -I
tank/raid1-2@replication_09-09-12-19:40:00 tank/raid1-2@nc_test05 | nc
192.168.10.201 1337
/Result on Server B:
/root@oi151a5-2:~# zfs list -t snapshot
NAME USED AVAIL REFER MOUNTPOINT
...
tank/raid1-2@replication_09-09-12-19:40:00 0 - 16K -
tank/raid1-2@nc_test05 0 - 16K -/
Best regards
Florian
