  • DOS application to allow remote management of files over serial link

    - by tomlogic
    Harken back to the days of DOS. I have an embedded DOS handheld device, and I'm looking for a tool to manage the files stored on it. I picture an application I can launch on the device that opens COM1 up for commands to get a directory listing, send/receive files via x/y/zmodem, move/delete files, and create/move/delete directories. A Windows application can then download a recursive file listing and then manage those files (for example, synchronizing with a local directory). Keep in mind that this is DOS -- 8.3 filenames, 640K of RAM and a 19200bps serial link (yuk!). I'd prefer something with source in case we need to add additional features (for example, the ability to get a checksum of a file for change detection). Now that I've written this description, I realize I'm asking for something like LapLink or pcAnywhere. Norton no longer sells DOS versions of pcAnywhere and LapLink V for DOS seems pricy at $50. Are you aware of any similar apps from those good old days?

  • How to Bridge Two Ethernet Ports on Mac OS X

    - by Rabarberski
    How can I bridge two wired ethernet interfaces on Mac OS X (e.g. the current MacPro comes with two ethernet ports)? Googling turned up (e.g. this Apple forum post and this openvpn post) that this is fairly easy on Linux (using the brctl command) and under Windows (via Network Connections right-click Bridge Connections), but how is it done under Mac OS X? BTW: There also doesn't seem to be a macport for brctl ('port search brctl' didn't turn up any results) Note: I don't want to have 'internet sharing', which creates a new network (by handing out network addresses in a new range). I want to really 'bridge' two interfaces so to keep the same network subnet.

  • xrandr doesn’t detect display ports

    - by Psyhister
    I have a ThinkPad T510 laptop with Gentoo Linux installed on it and I can’t manage to get VGA and DisplayPort working. xrandr -q won’t show them, so I’m guessing, that there’s a problem with my kernel configuration, but I wasn’t able to find the options responsible for these ports. Here’s the output from xrandr -q: xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 175, current 1366 x 768, maximum 1366 x 768 default connected 1366x768+0+0 0mm x 0mm 1366x768 50.0* 51.0 52.0 1024x768 53.0 54.0 832x624 55.0 800x600 56.0 57.0 58.0 59.0 60.0 720x400 61.0 700x525 62.0 640x512 63.0 64.0 640x480 65.0 66.0 67.0 68.0 69.0 640x400 70.0 640x350 71.0 576x432 72.0 512x384 73.0 74.0 75.0 76.0 77.0 416x312 78.0 400x300 79.0 80.0 81.0 82.0 83.0 360x200 84.0 320x240 85.0 86.0 87.0 88.0 320x200 89.0 320x175 90.0 Can anyone help me figure out what the problem is and how to get the video connections to work?

  • SSH: Tunnel multiple ports to remote server

    - by user1594322
    See attached diagram. Host A - Windows server Host B - Linux server Host C - VMWare ESXi server From host A I can SSH to host B over the VPN tunnel. I can ping host C from host B, but not from host A. I am assuming this is because host C has lost its default gateway. Host C is a VMWware ESXi server, so I would need to tunnel several ports (80,443,902) in order to reach host C from host A. What is the correct ssh syntax to create the tunnel in order to reach host C from host A, and can I do it using a single command, or do I need to run three commands (one for each port, 80,443,902)?

  • SNMP based network discovery (switches), device (ports on switches) power management

    - by SaM
    In a enterprise network, what would be the right way to generate a list of switches (SNMP managed) Is it reasonable to ask the organization to supply a list such as this: Switch name IP Address of switch Location SNMP community strings Or are there standard ways to run discovery scans - UDP broadcasts? After having generated a repository such as the above; given a single switch, how to query it for the list of all devices attached to it? Finally, how to selectively power down/power up ports? (remotely - using SNMP) Platform is going to be .NET based (C#) and the library being used is SharpSNMP

  • Setup VLAN agnostic ports on HP ProCurve 1810G (Ingress Filter, Trunking)

    - by Thomas
    I am wondering if it is possible to configure some ports of the web managed ProCurve Switch 1810G to participate in all VLAN traffic. Even if no VLAN with that ID has been set up inside the switch. The issue is that I have two virtualization servers that will use yet unknown VLANs of a certain range to communicate with each other. But the range is much larger than the 64 supported VLANs this switch can manage. The switch also offers static and LACP Link Trunks. But I guess there will also apply the Ingress Filter that drops packets with unconfigured VLAN IDs? A separate unmanaged switch that connects the two hosts and one ProCurve Port would work, but maybe I do not have to? Thanks

  • USB ports not recognizing devices (vista)

    - by frank
    I'm trying to fix a problem on a Vista machine where all the USB ports seem to have power but they don't recognize devices plugged into them. It seemed to start after I plugged my mp3 player (sansa clip) into it and disconnect it. So it sounds similar to this article http://support.microsoft.com/kb/817900 but that was for XP. And I did try all the fixes (including the registry entry) but they did not help. It also sounds similar to this SU question 50110 but I don't think it is the mother board. I have see other places that suggest reinstalling the OS...but that seems like a last resort type of thing. I have also seen a suggestion of doing a system restore but not sure if that will help. Any ideas of what I can try?

  • Com port redirection from Windows 7 to Windows Server 2008 R2

    - by Ola Eldøy
    We use "Copy file.prn to \tsclient\com1" to print from a TS session to a locally attached serial printer. This works fine from Windows XP, but when trying it from a Windows 7 client computer, we get an "Access is denied" error message. And yes, the check box of COM port is selected on the Local Resources tab of the Remote Desktop Connection client. Any pointers? Has anyone even managed to do this successfully?

  • Sonicwall - dual WAN ports - switch from one to another

    - by Charles
    Hi, Folks! I'm using a SonicWall NSA 240 which has two WAN ports (T1 and Comcast) and the LAN port has a cable which connects to a switch. From the switch, several cables connect to other switches. The SonicWall doesn't have DHCP enabled; one of our domain controllers running Windows Server 2003 also functions as a DHCP server. Is there a way for a user in our network to change connection from T1 to Comcast as their ISP or vice versa? In other words, if a user is connected via the T1, can he/she somehow connect via Comcast instead? Thanks, in advance, for your help! Sincerely, Charles

  • RAID across SAS controller ports

    - by BlueGene
    Hi, I'm managing a HP DL360 G5 machine. It has a SAS controller with two ports. Port 1 is attached to 4 drive bays and Port 2 has 2 bays. The machine currently has 3 drives connected to Port 1 with RAID 5 configuration. I'm trying to max out the bays by adding 1 disk in port 1 and 2 in port 2. Can I group those three disks(1 disk-port, 2 disks-port 2) in a RAID 5 configuration?

  • How to disable power to USB ports when laptop is in sleep mode

    - by Greg
    I have a Windows7 laptop with two external 2.5" HDDs and a cooling pad connected through USB ports. When I put the laptop to sleep, these devices are still powered on - the fan in the cooling pad is still spinning, the drives are still spinning. I want to set it all up so that they power down when in sleep. I tried setting the Allow the computer to turn off this device to save power option in the USB Root Hubs' Properties in Device Manager and enabling USB selective suspend in power options - it didn't work. As it's a laptop, BIOS options are extremely locked down, so I can't even see anything relevant to sleep in there. Is it even possible to do this?

  • What ports does Advantage Database Server need?

    - by asherber
    I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately. ADS lives on \\server, and it's listening on port 1234. When \\client tries to connect to \\server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \\server:1234\tables, I get error 6097, bad IP address specified in the connection path. \\server is pingable from \\client, and I can telnet to \server:1234. If I try to connect from a client machine inside the firewall, either connection path works fine. It seems there must be something else I need to open in the firewall. Any ideas? Thanks, Aaron. Edit: I should have specified that the firewall is open to \\server:1234 specifically for TCP traffic. Is UDP involved here in some way?

  • Electricity in VAIO laptop ports while plugged in

    - by SRbH
    I have VAIO E series (SVE) laptop. While charger plugged in, touching VGA/HDMI/USB port metal casing gives me burning sensation. So, i checked it with voltmeter and i found that while plugged in there is presences of DC +1.0 V. Same case with my friend's VAIO E Series (VPCEH). Service center says this is normal. But i do not believe them as it is not the case with Dell Inspiron. Please let me know if you are facing same problem with VAIO and is it hazardous to devices which i connect to these ports (like HDD, LED, etc)?

  • Does a USB to RJ-45 console cable exist?

    - by Carl Flippin
    I am aware of the RJ-45 to DB9 adapter commonly used on cisco routers to access console. I am aware of the USB to DB9 adapters to allow laptops without serial to get a serial port. I am looking for a USB to RJ-45 adapter so I don't have to chain two adapters together. I have searched everywhere but even the pre-packaged solutions seem to have the two adapters chained together. Does such a thing exist? If it doesn't is there some technical reason it cannot? It seems like a manufacturer would just have to wire the DB9 end of the USB adapter differently and it would work just fine plugged straight into the console port of the router.

  • juniper j2300 console connection?

    - by Aceth
    I've been given a Juniper Networks J2300 router, but I've never used a juniper device before and no idea where to begin on how to connect to the console of the device. I have a serial to RJ45 cable but not sure on how to connect to the device. Do I use specific software or just use something like minicom (linux hyperterminal alternative)? I've had a look on the juniper website and couldn't find anything :( Any help would be truly appreciated, cheers

  • Declaring multiple ports for the same VirtualHosts

    - by user65567
    Declare multiple ports for the same VirtualHosts: SSLStrictSNIVHostCheck off # Apache setup which will listen for and accept SSL connections on port 443. Listen 443 # Listen for virtual host requests on all IP addresses NameVirtualHost *:443 <VirtualHost *:443> ServerName domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/domain/public" <Directory "/Users/<my_user_name>/Sites/domain/public"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on ... </VirtualHost> How can I declare a new port ('listen', ServerName, ...) for 'domain.localhost'? If I add the following code, apache works (too much) also for all other subdomain of 'domain.localhost' (subdomain1.domain.localhost, subdomain2.domain.localhost, ...): <VirtualHost *:80> ServerName pjtmain.localhost:80 DocumentRoot "/Users/Toto85/Sites/pjtmain/public" RackEnv development <Directory "/Users/Toto85/Sites/pjtmain/public"> Order allow,deny Allow from all </Directory> </VirtualHost>

  • How to forward blocked ports by ISP

    - by KiDo
    So I've been trying to setup a TeamSpeak 3 server on my pc but ports (9987,10011,30033) are blocked by my ISP, I've contacted them to unblock them but they didn't accept, and it's the fastest ISP in my city (as living in a 3rd world country) so it's not a good idea to connect to another ISP. The thing is, I've tried Your-Freedom to connect to tunnel my connection & SocksCap. The problem is, when TS works with SocksCap it doesn't show a WAN-IP that friends will use to connect to my server It says "Needs to be Requested" and when I press the Request button, I get nothing. So, any idea what's wrong if someone has done this before? or if you have any other suggestion to run a TS server, would be very glad to hear it and really appreciate that. P.S. as I've mentioned before, living in a 3rd world country, makes me unable to buy a VPS even the cheapest one cause there's no Visa, Credit, or paypal. so that won't work. Thanks in advance.

  • What ports to open for mail server?

    - by radman
    Hi, I have just finished setting up a Postfix mail server on a linux (ubuntu) platform. I have it sending and receiving email and it is not an open relay. It also supports secure smtp and imap. Now this is a pretty beginner question but should I be leaving port 25 open? (since secure smtp is preferred). if so then why? Also what about port 587? Also should I require any authentication on either of these ports? Please excuse my ignorance in this area :P

  • Bound external Cisco CIGESM ports to a specific BladeServer

    - by Vinícius Ferrão
    We have an IBM BladeCenter with 14 blade servers and one external Cisco CIGESM for Ethernet connectivity. Since this hardware is a little old, we will use it for other services, and we want to run a pfSense instance on one of the blades. It's just an Firewall Appliance, but it needs two network interfaces: one for the WAN and the other one for LAN access. Our architecture works on top of static routes, we don't use NAT, so we got the WAN IP in one interface routing to the another one. The main problem is how to plug the WAN cable in one of the four external ports and make it exclusive to the blade server containing the firewall. And we also need an exit port that goes through a 3COM 4200G switch that makes the internal routing and VLAN separation. Thanks in advance

  • Looking for a router with multiple WAN ports and load balancing

    - by Cyrcle
    I'm going to be moving in a few months. The location I'm moving to is great except it's on a road with very few people, so the internet access option is limited to DSL at 1.6Mbps down, 384kbps up. This is much slower than I'm used to. One option is to get at least two of the DSL lines. There's also good possibility that I'll be able to get WiMax or similar. I've been looking around a bit and it seems like what I need is a load balancing router with multiple WAN ports. Can anyone recommend some good ones? I could also go with a small power efficient Linux box with multiple NICs. What would be good software for that? It'd need to be able to handle around 10Mbps. Thanks for any help

  • Log incoming requests on Ubuntu (ports 80, 443)

    - by Maxim Eliseev
    We have Tomcat running on Ubuntu server. It runs a web service, open to the internet. Sometimes it has a sudden spike of traffic and goes down. There is nothing unusual in Tomcat access logs. I guess it is because some of the requests are so 'heavy' that they never finish and hence are not recorded to Tomcat access logs. Is there a way to configure Ubuntu to log incoming requests in the following format (below)? Date, Time, URL (with query string params), IP address (of client) There should be one line per request. Each request should be logged before it is executed. Only incoming requests to ports 80 and 443 should be logged.

  • Accessing mySQL from two ports: Problems with iptables

    Hi! I'm trying to make my mySQL-server (running on Ubuntu) listen on port 3306 and 110, because I would like to access it from a network with very few open ports.

  • Which ports for IPSEC/LT2P?

    - by Matt
    I have a firewall/router (not doing NAT). I've googled and seen conflicting answers. It seems UDP 500 is the common one. But the others are confusing. 1701, 4500. And some say I need to also allow gre 50, or 47, or 50 & 51. Ok, which ports are the correct ones for IPSec/L2TP to work in a routed environment without NAT? i.e. I want to use the built in windows client to connect to a VPN behind this router/firewall.
