(IDG) -- While there are plenty of specialized network management applications to attend identify and fix problems, less than a dozen of them are absolutely essential for troubleshooting. These are the tools you'll exhaust the most, so do positive your toolkit is equipped with these 10 basic necessities for effective, efficient network management.
1. Ping.Ping tests end-to-end connectivity by sending an Internet Control Message Protocol packet to espy if a node or device is online and responding. One of the first steps in troubleshooting a network is to exhaust the generic IP loopback address 'ping 127.0.0.1' to test the local device.
You can also exhaust ping to test the maximum transmission unit - the maximum amount of data that can live carried in each packet end-to-end. Moreover, you might exhaust ping to determine the round-trip time in milliseconds to another device on the network.
However, any tools that generate a lot of traffic through your ISP's routers will probably trigger an alarm. If your traffic increases CPU usage or saturates a link to the Internet, your ISP may investigate and circumscribe your activities.
2. Traceroute.Traceroute builds on the functionality of ping by evaluating the hops along a path and calculating the time it takes a packet to travel from one router to the next.
For example, affirm you ping a remote device but it takes a long time to receive a response. To learn where the detain is occurring, exhaust traceroute to examine the round-trip time to each of the routers along the path.
3. Protocol analyzer/network analyzer.A protocol analyzer (sometimes called a network analyzer) is an absolute necessity for understanding what your network is doing. Analyzers capture any packets, or specific packets defined in a filter, into a trail buffer. The analyzer decodes the packets to give you a readable definition of the contents. Some more advanced analyzers, such as Network Associates' Sniffer Pro, can also interpret the communications patterns to provide alarms and troubleshooting recommendations.
AG Group's EtherPeek is another favorite analyzer, and Windows NT comes with a no-frills analyzer called Network Monitor. EtherPeek and Network Associates' Sniffer Basic cost less than $1,500, whereas Sniffer Pro and other more advanced analyzers cost closer to $10,000.
4. Port scanner.Port scanning can expose you what services are available on a remote device. Just as using ping could come by you into trouble, your ISP or the targeted system may construe port scanning or port probing as a hostile action or intrusion. Moreover, port scanning may violate your ISP usage agreement.
5. Nslookup/DIG.Basic nslookup utilities do queries to Domain appellation System (DNS) servers. An nslookup query will request the default DNS server for host name-to-IP address resolutions. Domain Internet Grouper (DIG) is similar to nslookup, but provides a more detailed reply from the DNS server. For example, a simple nslookup reply for www.internal.net analysis.org returns the following information:
Translated name:server.netanalysis.comIP address:10.23.4.99Alias:www.internal.netanalysis.orgDIG returns the information above plus the following:Name servers:AUTH00.NS.INT.NETIP address: 10.23.66.1AUTH01.NS.INT.NETIP address: 10.23.77.1
6. ARP.6. ARP. Address Resolution Protocol keeps track of IP addresses and their corresponding physical network addresses. You can read ARP tables to identify the hardware address that is being used to dispatch packets.
7. Route.Route is a utility that lets you read and maneuver IP routing tables on a local device. The tables determine the next hop along a path to a host or network. These tables also accommodate the default gateway entry if one exists.
8. SNMP tools.SNMP management tools provide a artery to amass and pomp Management Information base (MIB) data extracted from devices that support SNMP agents. You can track SNMP devices via an alarming/alerting system that notifies the SNMP manager when a user-defined threshold has been exceeded. However, one of the main obstacles to implementing an SNMP management system is the want of a just cross-platform product.
9. Cable tester.You requisite a cable tester to precisely test and troubleshoot network wiring. Tools such as Microtest's OmniScanner often near configured with an entire set of tests to evaluate cable integrity and interference. Cable testers can report total cable lengths, pass/marginal/fail test results, near-end crosstalk, attenuation, impedance and more.
Some cable-tester manufacturers define their tools as network analyzers. Although these devices may provide some information about the packet types crossing the wire, such as broadcasts, they are no substitute for just network analyzers that pomp packet contents.
10. Combination tools and motley utilities.There are several needful combination troubleshooting tools, including NetScanTools Pro 2000 and the AG Group's NetTools. Each provides a group of utilities that let you port scan, ping, trail route and effect nslookup, saving hours of troubleshooting time. Of the two, NetTools is less expensive and offers a subset of the tools included in NetScanTools Pro 2000.
You may also want to consider other utilities that provide basic configuration and connection information, such as Windows WINIPCFG, IPCONFIG and netstat. An IP address calculator is another handy instrument to esteem around, and you may even live able to find a freeware version on the Internet.
Having the right tools makes the job of troubleshooting TCP/IP networks less painful and less mysterious.

Network path analysis tools dote traceroute are effective at examining how individual network devices influence the progress of packets across a network, but they rarely attend engineers understand the role that network security devices play.
Athena Security's fresh PathFinder network path analysis product offers such visibility into security infrastructure. Network engineers can upload configuration data of firewalls, switches and routers into the tool, which generates an offline, virtual model of a network. They can then simulate packet transmission through this network model, and PathFinder predicts how device configurations and firewall rules will influence packet flows.
After segmenting the DMZ of the network at convenience store chain Kwik Trip, LAN and WAN administrator Chuck Serauskas discovered that unavoidable types of traffic were getting hung up in the segments. He used PathFinder to troubleshoot the problem.
"Since they got [PathFinder] we've been using it to troubleshoot… how the path runs through their ASA [Cisco Adaptive Security Appliance]," he said. "For PCI we've recently split their DMZ into four different DMZs. When they first set it up, they didn't esteem the routing exactly right through it, and their VMware guy was having some issues with some of the servers that they had in the DMZ."
With PathFinder's offline network path analysis features, Serauskas used his device configurations to create a model of his network and sent simulated packets through the DMZ. He saw that the ASA was intercepting unavoidable packets as they passed through it. He examined the rules on the ASA and discovered that some entries were sending the packets through an older path that had gone unused before segmentation.
"We just had to change the path on the DMZ — do the proper changes on the firewall for it — and once they made the changes to the config, they ran a fresh test [in PathFinder]," he said. "Once they knew the IP that [the VMware admin] was trying to come by through had traveled correctly, they made the change [in production].
Network path analysis tools rarely consider security
Network engineers esteem many tools at their disposal for network traffic analysis, from simple utilities dote traceroute to larger systems management products with network path analysis capabilities, such as Opnet and Compuware. However, most of these tools concentrate on network devices and hosts— not network security devices.
"I've heard plenty of war stories where a firewall rule change ended up creating a performance problem for an application. It's not normally a status where you peek for a performance problem, but it can esteem an impact,” said Jim Frey, research director for network management at Enterprise Management Associates.
In some IT organizations, the admins who exhaust network traffic analysis tools and network path analysis tools want fluency in firewall rules and settings, so a instrument that can provide a visual model of a firewall's upshot on network paths can live handy.
"Firewall rules come by lengthy, so to live able to provide some visual representation of how their firewall works is beneficial to those who don't live in firewall code every day," said Richard Barretto, senior information security analyst with the Healthcare Government Billings Solution Group at banking technology provider FIS Global.
Barretto recently purchased PathFinder and FirePAC, Athena's firewall management product. He acquired the tools in order to improve his organization's firewall auditing processes, but he also recognizes PathFinder's potential as a network traffic analysis and troubleshooting tool.
"You can actually troubleshoot unavoidable traffic that is going from one source to a destination, and based on rules settings figure out where traffic might quit or if there are any gaps," he said.
Finding mistakes with network path analysis
PathFinder is also useful for discovering gaps in network security that allow packets to fade where they shouldn't.
"When they peek over a client's network, they always assume there is going to live some aspect of network security that will fail, and the sinful guy will come by into some point of the network if he tries difficult enough." said Larry Rosen, security analyst with information security services firm Jacadis. "With a instrument dote PathFinder, they can peek and affirm if someone goes in from this level, where could they go? [We exhaust it] to try to resolve threats that a particular pocket will open on the network. So [our clients] can tighten up their rules if they requisite to."
Many companies want a full-time firewall manager, and non-specialists will often insert ad hoc rules to a firewall while testing a fresh application on a network, Rosen said. Then they forget to remove that rule after the test is complete. That rule change can potentially open up a hazardous vulnerability. A network traffic analysis instrument with suited visualization features can point a network to such a problem quickly."
Two other firewall lifecycle management vendors, Skybox Security and RedSeal Systems, esteem network path analysis capabilities similar to Athena PathFinder, but they are fragment of larger product suites, whereas PathFinder is a standalone product that network engineers without direct control over firewall infrastructure could exhaust for troubleshooting, Rosen said.
"In fact, network engineers could insert PathFinder into an overall change management process," said Jerod Brennen, senior security analyst at Jacadis. "If you had a router config file or firewall config file that represented a post-change world, you could flee queries against unavoidable faultfinding path services to evaluate whether that traffic is going to stream or not."

Why Can’t I Connect? is an open source instrument which can attend to identify and decipher TCP/IP connection errors.
Typically you'll exhaust the program to try and connect to one of many common server types (Microsoft SQL Server, MySQL Server, FTP, SFTP, IMAP, POP3, SMTP, IRC, LDAP and Usenet are supported, along with generic servers and clients). Why Can’t I Connect? then tries to do the connection for you, reporting on what happens at every stage, and offering feasible explanations for whatever errors crop up.
If you can't receive email from a POP3 server, say, you would elect the POP3 option, enter your server appellation or IP address, and optionally select a protocol (STARTLS, SSL/ TLS) or enter a port. (You don't esteem to enter a user appellation or password at any point, and so there's no requisite to worry about security: Why Can't I Connect? tries to compass the server only, it doesn't ply authentication.)
Once you’re set up, click OK and Why Can't I Connect? attempts to do the connection, displaying its various steps in the program's trail window. This includes identifying the current host name, checking for a bindable IP address, binding it to a socket handle, setting the receive and dispatch timeouts, locating an IP address for the server and trying to do the connection.
If any of this fails then an error message appears with feasible explanations: "your network connection is down", "your DNS server is down", "the port is being blocked by a firewall", "the server is slow", and so on.
This final analysis won't usually give you a definitive answer. When they tried running a POP3 connection to a web server, for instance, they got a “permission denied” error, with suggestions including "your network connection is down", "the port is not listening/ active", "the port is being blocked by a firewall", "the maximum connections for the server has been exceeded". The second was reform -- there was nothing listening at port 110 -- but the program has no artery to know that for sure, and you'll requisite to enact more travail to eddy its report into a solution.
Why Can’t I Connect? can attend point you in the right direction, though, and it has some welcome prize features thrown in. Bridging (tracing the conversation between an existing client and server) is their favourite, but there are also tools to report on connecting/ listening/ reserved ports, and a scripting option can automate testing to track down intermittent errors. fade grab a copy immediately for your troubleshooting toolkit.
