Re: [smartos-discuss] Unable to restore VM with LOFSs configured

[Jon Dison]

I just tried the operation again with the latest PI released yesterday and
am still having the same troubles.  Any ideas?

[root@x10slm /opt/backups]# cat lofstest | vmadm receive
Unable to complete install for 847ed527-c551-4a41-91bd-c9994d960fb4 zone is
still missing: 1 filesystems

[smartos-discuss] Protection against DDoS

[Rohit Singh]

Hi,

We've been using SmartOS since quite some while. Wanted to know if there
are any tweaks/services that can help protect against tcp-syn type DDoS
