Adding new server to tree -- hangs at "synchronizing schema"

Current environment:
two servers running RHEL 7/eDirectory 9.0.4
one server running RHEL 6 / eDirectory 8.8.8 SP5

I am deploying a new RHEL 7/eDir 9.04 server. When I run "ndsconfig -add
...." it hangs forever at "Synchronizing schema" ("forever" in this
context means "more than an hour").

What could be happening to cause this?

Thanks

Re: Adding new server to tree -- hangs at "synchronizing schema"

A likely cause is a misconfiguration of your environment, usually a
firewall blocking connectivity among systems. Be sure firewalls, both
network and host level firewalls, allow connectivity from every eDirectory
box to every other eDirectory box. Most of the time firewalls only block
unsolicited inbound traffic, so you usually need only check the INPUT
chain in Netfilter (via iptables) to be sure there is an allowance for (by
default) TCP 524 from the other systems (or all systems as is also common).

It may be useful to see if the ndsd.log file (by default under
/var/opt/novell/eDirectory/log) has anything useful. It may also be
useful to see what network connections the new system is trying to make at
the time:


sudo /usr/sbin/ss -planeto | grep ndsd
/usr/sbin/ss -planeto | grep SYN

It was the firewall, sure enough. That's what I get for not checking to
make sure the people who deploy my Linux systems actually follow
directions.

Glad to hear it; I am in the habit of checking/verifying for this very
reason; thank-you for posting your results, as they will likely help others.
