Here’s the Top PingPlotter Alternatives & Replacements for Network Connectivity Troubleshooting and Traceroute Type Features!
It is fairly easy to obtain DNS information for a domain listed by name or IP address. You can use the following procedure regardless of what platform your DNS is running on. You can also use this to verify what names your DNS thinks it is resolving, since this won’t necessarily match your hosts file. […]
In addition to resolving NetBIOS names for small networks, the LMHOSTS file can be used to back up WINS. Since the cached entries are referred to first, you can manually reset the cache of a corrupt or missing domain by reloading the entries in the LMHOSTS file. Make sure your system has the LMHOSTS checked […]
We’ve found that a star topology generally works best for WINS replication, with push/pull replication from one central hub. One indication that your WINS database entries are invalid is if you get “no domain controller available” errors between trusted domains in the system event log. This can almost always be cleared up by disabling replication […]
We’ll start out simple in this section with just three hosts, a cname for www, and an mx record. As we integrate DNS with other services we will add more sections. We are using Red Hat 7.1, but there is little here that is distribution-specific. The only thing that might change is the way you […]
We will explore rndc, which is a new tool with BIND 9 that takes the place of ndc in BIND 8. First we need to create a key using dnssec-keygen: [root@srv-3 /root]# dnssec-keygen -a hmac-md5 -b 256 -n user rndc Krndc.+157+34404 [root@srv-3 /root]# ls Krndc.+157+34404.key Krndc.+157+34404.private [root@srv-3 /root]# cat *.private Private-key-format: v1.2 Algorithm: 157 (HMAC_MD5) […]
