  • Configure vlan on Netgear switch via SNMP

    - by Russell Gallop
    I am trying to configure vlans on a netgear GS752TSX from the Linux command line with netsnmp. I have created vlan 99 on the web interface now want to control the pvid settings, egress and tagging. I have identified these as the MIBs I need to change: dot1qPvid.<port> dot1qVlanStaticEgressPorts.99 dot1qVlanStaticUntaggedPorts.99 Pvid works as I expect: $ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qPvid.17 u 99 Q-BRIDGE-MIB::dot1qPvid.17 = Gauge32: 99 $ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qPvid.17 Q-BRIDGE-MIB::dot1qPvid.17 = Gauge32: 99 and so do the egress ports: $ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticEgressPorts.99 x 'ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00' Q-BRIDGE-MIB::dot1qVlanStaticEgressPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 $ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticEgressPorts.99 Q-BRIDGE-MIB::dot1qVlanStaticEgressPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 But untagging the ports doesn't seem to remember my setting: $ snmpset -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticUntaggedPorts.99 x 'ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00' Q-BRIDGE-MIB::dot1qVlanStaticUntaggedPorts.99 = Hex-STRING: FF FF FF FF FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 $ snmpget -r 1 -t 20 -v 2c -c private <switch> dot1qVlanStaticUntaggedPorts.99 Q-BRIDGE-MIB::dot1qVlanStaticUntaggedPorts.99 = Hex-STRING: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 I have tried netsnmp 5.4.1 and 5.7.2.

  • What are some good, IP Address Management solutions for IPv6? [closed]

    - by Russell Heilling
    There are a number of open source IPAM tools available for IPv4 address management; however there seems to be a distinct lack of actively updated tools available for IPv6. Other than FreeIPdb (code no longer maintained) or the RIPE Database (I have seen some customisations to the RIPEdb that allow for enterprise/ISP IPAM but it seems like overkill for a system that will probably only ever handle one /32 worth of space). Are there any other options that I'm missing? (Database only please. I know vi can be used for flat text IPAM, that's how I'm handling our /32 at the moment, but I don't see it scaling for much longer) It doesn't have to be open source but what are folks doing to manage IPv6 in a dual stack environment

  • Multiple public keys for one user

    - by Russell
    This question is similar to SSH public key authentication - can one public key be used for multiple users? but it's the other way around. I'm experimenting on using ssh so any ssh server would work for your answers. Can I have multiple public keys link to the same user? What are the benefits of doing so? Also, can different home directories be set for different keys used (all of which link to the same user)? Please let me know if I'm unclear. Thanks.

  • Seeking recommendations on resolving sporadic network connectivity latency for Notes client

    - by Russell Maher
    I have Domino servers in geographically disperse data centers in the U.S. Sometimes when I open an NSF on one of those servers the connection times out then when I open the NSF again it connects immediately. This has been going on for years and during that time I have upgraded and changed my own internet connection and moved servers to different data centers. Of course I have direct connection documents using fixed IP addresses. When I do a Notes client Trace nothing is out of the ordinary. My business partner experiences the same thing from an entirely different city and different ISP but to the same servers. Never have any trouble connecting to the HTTP server, just over port 1352. Does anyone have any recommendations on a process to determine what is causing this problem?

  • Whole Lotta Virtualization Goin' On

    - by rickramsey
    Lately we've published a lot of content about virtualization. Here's a sampling. Podcat: Technology Preview of Transcendent Memory Turns out that in a virtual environment, RAM is the bottleneck. Not because it's slow, it's not, but because each CPU still had to use its own RAM. Which gets expensive. In this podcast, Dan Magenheimer describes how Oracle and the open source community taught the guest kernel in Oracle Linux to share its memory with other CPU's. Transcendent memory will wind up saving large data centers a lot of money. Find out how. Tech Article: How to Use Oracle VM Templates This article describes how to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. It also describes how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration. Tech Article: How to Set Up a Load Balanced Application Across Two Oracle Solaris Zones Install Apache Tomcat on two Oracle Solaris zones. Connect them across a VPN. And let the Integrated Load Balancer in Oracle Solaris 11 manage traffic. Presto: high(er) availability in a single server. Tech Article: How to Install Oracle RAC on Oracle Solaris Zone Clusters Learn how to implement a multi-tiered database environment that isolates database tiers and administrative domains, while taking advantage of centralized (and simpler) cluster admin.

  • Yes WinRT Devices Have a Desktop&hellip;But Not For Us

    - by D'Arcy Lussier
    So tonight this convo happened: Intrigued, I viewed the video Lee mentions and found that its the now infamous Brent Ozar video which shows a bug in Word on the Surface RT (you can read this article which talks about the tempest in a teacup that ensued). But Lee is correct – in the video, when Brent starts up Word 2013, we see this: That sure does look like a desktop doesn’t it! But…aren’t Windows RT devices *not* supposed to come with a desktop? Actually, it does. However, it’s not a *full* desktop. From Seth Rosenblatt’s fantastic Windows RT FAQ article: Windows RT will have a Desktop mode, but it will be restricted to pre-installed, Microsoft-produced software. This will include touch-optimized versions of Microsoft Word, Excel, PowerPoint, and OneNote as the new Microsoft Office So yes, there’s a desktop mode in Windows RT but no, you won’t be able to install apps to it. Confused yet? Read the rest of the Seth’s FAQ – it does a great job clearing the haze of confusion that Microsoft Marketing Merlins have cast upon all of us. D

  • C# Bind DataTable to Existing DataGridView Column Definitions

    - by Timothy
    I've been struggling with a NullReferenceException and hope someone here will be able to point me in the right direction. I'm trying to create and populate a DataTable and then show the results in a DataGridView control. The basic code follows, and Execution stops with a NullReferenceException at the point where I invoke the new UpdateResults_Delegate. Oddly enough, I can trace entries.Rows.Count successfully before I return it from QueryEventEntries, so I can at least show 1) entries is not a null reference, and 2) the DataTable contains rows of data. I know I have to be doing something wrong, but I just don't know what. private void UpdateResults(DataTable entries) { dataGridView.DataSource = entries; } private void button_Click(object sender, EventArgs e) { PerformQuery(); } private void PerformQuery() { DateTime start = new DateTime(dateTimePicker1.Value.Year, dateTimePicker1.Value.Month, dateTimePicker1.Value.Day, 0, 0, 0); DateTime stop = new DateTime(dateTimePicker2.Value.Year, dateTimePicker2.Value.Month, dateTimePicker2.Value.Day, 0, 0, 0); DataTable entries = QueryEventEntries(start, stop); UpdateResults(entries); } private DataTable QueryEventEntries(DateTime start, DateTime stop) { DataTable entries = new DataTable(); entries.Columns.AddRange(new DataColumn[] { new DataColumn("event_type", typeof(Int32)), new DataColumn("event_time", typeof(DateTime)), new DataColumn("event_detail", typeof(String))}); using (SqlConnection conn = new SqlConnection(DSN)) { using (SqlDataAdapter adapter = new SqlDataAdapter( "SELECT event_type, event_time, event_detail FROM event_log " + "WHERE event_time >= @start AND event_time <= @stop", conn)) { adapter.SelectCommand.Parameters.AddRange(new Object[] { new SqlParameter("@start", start), new SqlParameter("@stop", stop)}); adapter.Fill(entries); } } return entries; } Update I'd like to summarize and provide some additional information I've learned from the discussion here and debugging efforts since I originally posted this question. I am refactoring old code that retrieved records from a database, collected those records as an array, and then later iterated through the array to populate a DataGridView row by row. Threading was originally implemented to compensate and keep the UI responsive during the unnecessary looping. I have since stripped out Thread/Invoke; everything now occurs on the same execution thread (thank you, Sam). I am attempting to replace the slow, unwieldy approach using a DataTable which I can fill with a DataAdapter, and assign to the DataGridView through it's DataSource property (above code updated). I've iterated through the entries DataTable's rows to verify the table contains the expected data before assigning it as the DataGridView's DataSource. foreach (DataRow row in entries.Rows) { System.Diagnostics.Trace.WriteLine( String.Format("{0} {1} {2}", row[0], row[1], row[2])); } One of the column of the DataGridView is a custom DataGridViewColumn to stylize the event_type value. I apologize I didn't mention this before in the original post but I wasn't aware it was important to my problem. I have converted this column temporarily to a standard DataGridViewTextBoxColumn control and am no longer experiencing the Exception. The fields in the DataTable are appended to the list of fields that have been pre-specified in Design view of the DataGridView. The records' values are being populated in these appended fields. When the run time attempts to render the cell a null value is provided (as the value that should be rendered is done so a couple columns over). In light of this, I am re-titling and re-tagging the question. I would still appreciate it if others who have experienced this can instruct me on how to go about binding the DataTable to the existing column definitions of the DataGridView.

  • CA2000 passing object reference to base constructor in C#

    - by Timothy
    I receive a warning when I run some code through Visual Studio's Code Analysis utility which I'm not sure how to resolve. Perhaps someone here has come across a similar issue, resolved it, and is willing to share their insight. I'm programming a custom-painted cell used in a DataGridView control. The code resembles: public class DataGridViewMyCustomColumn : DataGridViewColumn { public DataGridViewMyCustomColumn() : base(new DataGridViewMyCustomCell()) { } It generates the following warning: CA2000 : Microsoft.Reliability : In method 'DataGridViewMyCustomColumn.DataGridViewMyCustomColumn()' call System.IDisposable.Dispose on object 'new DataGridViewMyCustomCell()' before all references to it are out of scope. I understand it is warning me DataGridViewMyCustomCell (or a class that it inherits from) implements the IDisposable interface and the Dispose() method should be called to clean up any resources claimed by DataGridViewMyCustomCell when it is no longer. The examples I've seen on the internet suggest a using block to scope the lifetime of the object and have the system automatically dispose it, but base isn't recognized when moved into the body of the constructor so I can't write a using block around it... which I'm not sure I'd want to do anyway, since wouldn't that instruct the run time to free the object which could still be used later inside the base class? My question then, is the code okay as is? Or, how could it be refactored to resolve the warning? I don't want to suppress the warning unless it is truly appropriate to do so.
