salt.modules.dnsutil¶

Compendium of generic DNS utilities

salt.modules.dnsutil.A(host, nameserver=None)¶

Return the A record(s) for host.

Always returns a list.

CLI 范例:

salt ns1 dnsutil.A www.google.com

salt.modules.dnsutil.AAAA(host, nameserver=None)¶

Return the AAAA record(s) for host.

Always returns a list.

2014.7.5 新版功能.

CLI 范例:

salt ns1 dnsutil.AAAA www.google.com

salt.modules.dnsutil.MX(domain, resolve=False, nameserver=None)¶

Return a list of lists for the MX of domain.

If the 'resolve' argument is True, resolve IPs for the servers.

It's limited to one IP, because although in practice it's very rarely a round robin, it is an acceptable configuration and pulling just one IP lets the data be similar to the non-resolved version. If you think an MX has multiple IPs, don't use the resolver here, resolve them in a separate step.

CLI 范例:

salt ns1 dig.MX google.com

salt.modules.dnsutil.NS(domain, resolve=True, nameserver=None)¶

Return a list of IPs of the nameservers for domain

If 'resolve' is False, don't resolve names.

CLI 范例:

salt ns1 dig.NS google.com

salt.modules.dnsutil.SPF(domain, record='SPF', nameserver=None)¶

Return the allowed IPv4 ranges in the SPF record for domain.

If record is SPF and the SPF record is empty, the TXT record will be searched automatically. If you know the domain uses TXT and not SPF, specifying that will save a lookup.

CLI 范例:

salt ns1 dig.SPF google.com

salt.modules.dnsutil.check_ip(ip_addr)¶

Check that string ip_addr is a valid IP

CLI 范例:

salt ns1 dig.check_ip 127.0.0.1

salt.modules.dnsutil.hosts_append(hostsfile='/etc/hosts', ip_addr=None, entries=None)¶

Append a single line to the /etc/hosts file.

CLI 范例:

salt '*' dnsutil.hosts_append /etc/hosts 127.0.0.1 ad1.yuk.co,ad2.yuk.co

salt.modules.dnsutil.hosts_remove(hostsfile='/etc/hosts', entries=None)¶

Remove a host from the /etc/hosts file. If doing so will leave a line containing only an IP address, then the line will be deleted. This function will leave comments and blank lines intact.

CLI范例:

salt '*' dnsutil.hosts_remove /etc/hosts ad1.yuk.co
salt '*' dnsutil.hosts_remove /etc/hosts ad2.yuk.co,ad1.yuk.co

salt.modules.dnsutil.parse_hosts(hostsfile='/etc/hosts', hosts=None)¶

Parse /etc/hosts file.

CLI 范例:

salt '*' dnsutil.parse_hosts

salt.modules.dnsutil.parse_zone(zonefile=None, zone=None)¶

Parses a zone file. Can be passed raw zone data on the API level.

CLI 范例:

salt ns1 dnsutil.parse_zone /var/lib/named/example.com.zone

salt.modules.dnsutil.serial(zone='', update=False)¶

Return, store and update a dns serial for your zone files.

zone: a keyword for a specific zone

update: store an updated version of the serial in a grain

If update is False, the function will retrieve an existing serial or return the current date if no serial is stored. Nothing will be stored

If update is True, the function will set the serial to the current date if none exist or if the existing serial is for a previous date. If a serial for greater than the current date is already stored, the function will increment it.

This module stores the serial in a grain, you can explicitly set the stored value as a grain named dnsserial_<zone_name>.

CLI 范例:

salt ns1 dnsutil.serial example.com
