[HELP] unable to copy ssh ID

[vzfanatic]

hi there,

I have 4 servers, one master (192.168.1.1), and i did 'pvecm create group', which worked without error. then i went to server 2 (192.168.1.2) and said 'pvecm add 192.168.1.1' and i get the error 'unable to copy ssh ID'. this server 2 is a fresh install from proxmox2 iso.

pvecm status on server 2 says ' cman_tool: Cannot open connection to cman, is it running ?'

/etc/init.d/cman status gives empty result
/etc/init.d/cman restart gives empty result.

aptitude install cman says;
Remove the following packages:
1) clvm
2) corosync-pve
3) fence-agents-pve
4) libcorosync4-pve
5) libopenais3-pve
6) libpve-access-control
7) libpve-storage-perl
8) openais-pve
9) proxmox-ve-2.6.32
10) pve-cluster
11) pve-manager
12) qemu-server
13) redhat-cluster-pve
14) resource-agents-pve
15) vzctl

which im sure i don't want to do.

i tested for multicast capabilities, and all answered as expected.

this is clean install on the three nodes, and no containers, so i can't understand why cman doesnt run, and why there is error on adding. i am using ssh on port 2222 if it matters.

id appreciate some ideas, ive googled the heck out of this.

thank you

cman_tool: Cannot open connection to cman, is it running ?

cman_tool: Cannot open connection to cman, is it running ?

That node is still not added to the cluster (add failed), so that is OK.

What if you run the following on 192.168.1.2:

# ssh-copy-id 192.168.1.1

# ssh-copy-id 192.168.1.1

says;
port 22: Connection refused

I change the port on the servers to increase security. if i tell it what port, the answer is;
Pseudo-terminal will not be allocated because stdin is not a terminal.
ssh: Could not resolve hostname umask 077; test -d .ssh || mkdir .ssh ; cat >> .ssh/authorized_keys: Name or service not known

If i ping the name or ip, the answer is icmp_req=1 ttl=64 time=0.121 ms

I'm going to change the port back to 22 in the meantime and see if that helps my problem.

 

[vzfanatic]

yes, that was what's wrong, after changing to port 22 it was able to be added to the cluster :-(

Is there someway to use non-standard port? I hate that hackers bang away at port 22 cause they know it's ssh.

cheers

Just add a ssh config for your cluster master:

cat /root/.ssh/config
Host mymaster
HostName 10.0.0.1
Port 10022
IdentityFile /root/ssh/id_rsa

The run pvecm add mymaster

I have the same problem. When i try the option ssh-copy-id <Master IP> i get the following error.

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
