The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
You must configure a fully-qualified domain name (FQDN) for the
Spacewalk proxy. Spacewalk does not consider
.local and .localdomain to
be valid domain names. Spacewalk clients must be able to resolve
the Spacewalk proxy's FQDN for both forward and reverse lookups
in DNS. If these conditions are not met, certificate validation
and PXE booting do not work and clients cannot register with the
Spacewalk server.
Verify that the host name returned by the
hostname command and the value of
HOSTNAME defined in
/etc/sysconfig/network are identical and that
this host name is consistent with the FQDN defined for the
system in DNS for both forward and reverse lookups, for example:
#hostnameswkproxy.us.mydom.com #grep HOSTNAME /etc/sysconfig/networkHOSTNAME=swkproxy.us.mydom.com #host swkproxy.us.mydom.comswkproxy.us.mydom.com has address 10.0.0.24 #host 10.0.0.2424.0.0.10.in-addr.arpa domain name pointer swkproxy.us.mydom.com.
Edit /etc/hosts and configure the actual IP
address for the FQDN and host name and not the loopback address
(127.0.0.1), for example:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.24 swkproxy.us.mydom.com swkproxy
The following table shows the network ports that a Spacewalk proxy uses, depending on its configuration.
Port/Protocol | Direction | Purpose |
|---|---|---|
80/tcp | Inbound and outbound | HTTP access |
443/tcp | Inbound and outbound | HTTPS access |
4545/tcp | Outbound | Monitoring (if enabled) |
5222/tcp | Inbound | Push support to Spacewalk clients (if required) |
5269/tcp | Inbound | Push support to Spacewalk proxies (if required) |
If the Spacewalk proxy needs to connect though a web proxy, you can configure the web proxy during installation.
Configure the Spacewalk server, proxies, and clients to use network time synchronization mechanism such as the Network Time Protocol (NTP) or Precision Time Protocol (PTP). Spacewalk requires that the system time on these systems are consistent to within 120 seconds.
