Dual NVidia graphics cards in Ubuntu / xorg.conf mania

- by John Zwinck

I have two NVidia graphics cards: Quadro NVS 295 (PCI Express, dual DisplayPort outputs) GeForce FX 5200 (PCI, DVI and VGA outputs) I have three identical monitors, two on DisplayPort and one on DVI. I'm on Ubuntu Hardy (and cannot currently dist-upgrade for separate reasons). I use the "nvidia" driver. What's new is the GeForce card and the third monitor. I currently have the dual DisplayPort monitors working fine. Here are the display-related parts of my xorg.conf: Section "ServerLayout" Identifier "Default Layout" Screen "PCI-Express Screen" 0 0 # adding this makes X fail to start: Screen "PCI Screen" 0 Inputdevice "Generic Keyboard" Inputdevice "Configured Mouse" EndSection Section "Module" Load "glx" # not sure why/if this is needed EndSection Section "Monitor" Identifier "DELL 2408WFP" Option "DPMS" EndSection Section "Device" Identifier "NVIDIA Quadro NVS 295" Driver "nvidia" Option "RenderAccel" "true" Screen 0 BusID "PCI:2:0:0" EndSection Section "Device" Identifier "NVIDIA GeForce FX 5200" Driver "nvidia" Option "RenderAccel" "true" Screen 1 BusID "PCI:6:4:0" EndSection Section "Screen" Identifier "PCI-Express Screen" Device "NVIDIA Quadro NVS 295" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+1200, 1920x1200 +0+0" EndSection Section "Screen" Identifier "PCI Screen" Device "NVIDIA GeForce FX 5200" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+0" EndSection I use nvidia-settings to configure my monitors, and it does not show the second GPU. lspci, though, shows: 02:00.0 VGA compatible controller: nVidia Corporation Unknown device 06fd 06:04.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] Which is where I got the BusID settings for the two devices (when I just had one device, I didn't have any BusID listed...and adding the BusID hasn't broken anything). What am I missing? How can I make nvidia-settings show my second GPU so I can then configure its monitor?

Automount in Ubuntu 9.10

- by easyrider

Hi, By default Ubuntu doesn't mount internal NTFS hard drives automatically. A fstab solution not working properly, because of conflicts with the "intelligent" mount system. If I add my hd in fstab and reboot - it will be mounted. But if I go to nautilus, open places panel and click eject button (unmount) and than click on hd again to mount it, I will get an error. In 9.04 to solve this problem you need to modify hal rules in /etc/hal/... preferences.fdi in my case I modified it for only one drive. <device> - <match key="storage.hotpluggable" bool="false"> - <match key="storage.removable" bool="false"> <merge key="storage.automount_enabled_hint" type="bool">false</merge> - <match key="storage.model" string="ST3250310NS"> <merge key="storage.automount_enabled_hint" type="bool">true</merge> </match> </match> </match> </device> But this is not working in 9.10 - devs removed this function from hal to devkit-disk or udev? I don't know. Could you please tell me where automount rules are stored in 9.10? And how to create new rules, and what program controls automount in 9.10?

Trouble connecting a Ubuntu system to IPv6 tunnel over NAT

- by John Millikin

I'm trying to set up an IPv6 tunnel, via Hurricane Electric's tunnel-broker service. I've configured my system using their example commands: # $ipv4a = tunnel server's IPv4 IP # $ipv4b = user's IPv4 IP # $ipv6a = tunnel server's side of point-to-point /64 allocation # $ipv6b = user's side of point-to-point /64 allocation ip tunnel add he-ipv6 mode sit remote $ipv4a local $ipv4b ttl 255 ip link set he-ipv6 up ip addr add $ipv6b dev he-ipv6 ip route add ::/0 dev he-ipv6 And have configured my desktop to be in my NAT router's DMZ. The router is running Tomato firmware. But I can't ping any IPv6 services: $ ping6 -I he-ipv6 '2001:470:1f04:454::1' PING 2001:470:1f04:454::1(2001:470:1f04:454::1) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes From 2001:470:1f04:454::2 icmp_seq=1 Destination unreachable: Address unreachable From 2001:470:1f04:454::2 icmp_seq=2 Destination unreachable: Address unreachable I can ping my local address: $ ping6 -I he-ipv6 '2001:470:1f04:454::2' PING 2001:470:1f04:454::2(2001:470:1f04:454::2) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes 64 bytes from 2001:470:1f04:454::2: icmp_seq=1 ttl=64 time=0.037 ms 64 bytes from 2001:470:1f04:454::2: icmp_seq=2 ttl=64 time=0.039 ms I don't know much about routing, but results I found online suggested the output of ip -6 route and ip addr could be useful: $ ip -6 route 2001:470:1f04:454::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 default dev he-ipv6 metric 1024 mtu 1480 advmss 1420 hoplimit 4294967295 $ ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 100 link/ether 00:1c:c0:a1:98:b2 brd ff:ff:ff:ff:ff:ff inet 192.168.1.10/24 brd 192.168.1.255 scope global eth1 inet6 fe80::21c:c0ff:fea1:98b2/64 scope link valid_lft forever preferred_lft forever 3: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 36:4c:33:ab:0d:c6 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 inet6 fe80::344c:33ff:feab:dc6/64 scope link valid_lft forever preferred_lft forever 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 00:76:62:6e:65:74 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 7e:29:5e:7c:ba:93 brd ff:ff:ff:ff:ff:ff 6: sit0: <NOARP> mtu 1480 qdisc noop state DOWN link/sit 0.0.0.0 brd 0.0.0.0 7: he-ipv6@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN link/sit 24.130.225.239 peer 72.52.104.74 inet6 2001:470:1f04:454::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::1882:e1ef/128 scope link valid_lft forever preferred_lft forever

Ubuntu NBR karmic boot freezes at fsck from util-linux-ng 2.16

- by BlueBill

Hi all, I have a netbook (emachine e250 - equivalent to an acer aspire one) and I have Ubunutu NBR 9.10 installed on it. Every other cold boot freezes at the following error message: "fsck from util-linux-ng 2.16" There is no disk activity, no activity what so ever. I have left the machine sit for over an hour and nothing. It takes a couple of hard resets to be able to boot properly. Once it boots everything works great (wireless, suspend/resume, etc.)! I have spent the last couple of weeks researching the problem and the only thing that seems to work is setting nolapic in the boot string in grub - it boots every time. Unfortunately, nolapic disables the second core and causes problems with suspend resume. At first I thought it was an fsck problem with the first partition on the hard disk as it is a hidden ntfs partition containing the windows xp recover information. So in /etc/fstab I set the partition so that it would be ignored by fsck. This didn't seem to do anything. I have these partitions: /dev/sda1 - an ntfs recovery partition /dev/sda2 - /boot /dev/sda3 - swap /dev/sda5 - / /dev/sda6 - /home I am running kernel version 2.6.31-19-generic and have all the patches (as indicated by update manager). I also have no splash screen so I can see the boot progress. I have only been using NBR since January, I have been using Ubuntu on my desktop since last June (2009-06). What logs should I be looking at? Is there a log for failed boots? Thanks, Troy

using remote MS Access database which connects to remote SQL server

- by Manjot

Hi, We have a Microsoft Access database + application (on Server A) which connects to a remote SQL server (Server B) using System DSN ODBC connection (on Server A) to the SQL database server. The users are open this Access database remotely as it is on a shared location on the server A. They still have to create a local ODBC connection on their computers to connect to Server B. Is there anyway that they can access the Access database and not have to create a local ODBC connection? thanks in advance

Deluge through a socks proxy server

- by tapan

To use deluge I use a socks proxy server. Everything was working perfectly till now. I use the following code to create the socks server: ssh -D 1080 user@remote-server In the proxy settings of Deluge I put the host as 127.0.0.1 and port as 1080 and use socks v4 (for some reason it didn't work with socks v5). This setup was working perfectly till now. Now suddenly I cannot download any torrents. The error I get is connection timed out. I checked the remote server and it seems it is not even being used. What can the error be ?

ssh-agent on ubuntu rapidly restarts

- by Santa Claus

I am attempting to use ssh-agent on Ubuntu 13.10 so that I will not have to enter my passphrase to unlock a key every time I want to use ssh or git. As you can see below, ssh-agent appears to be restarting for some reason. These commends were executed within a period of less than 5 seconds: andrew@zaphod:~$ ssh-agent SSH_AUTH_SOCK=/tmp/ssh-pqm5J0s70NxG/agent.2820; export SSH_AUTH_SOCK; SSH_AGENT_PID=2821; export SSH_AGENT_PID; echo Agent pid 2821; andrew@zaphod:~$ ssh-agent SSH_AUTH_SOCK=/tmp/ssh-VpkOH2WKjT1M/agent.2822; export SSH_AUTH_SOCK; SSH_AGENT_PID=2823; export SSH_AGENT_PID; echo Agent pid 2823; andrew@zaphod:~$ ssh-agent SSH_AUTH_SOCK=/tmp/ssh-EQ6X9JHNiBOO/agent.2824; export SSH_AUTH_SOCK; SSH_AGENT_PID=2825; export SSH_AGENT_PID; echo Agent pid 2825; andrew@zaphod:~$ ssh-agent SSH_AUTH_SOCK=/tmp/ssh-8Iij8kFkaapz/agent.2826; export SSH_AUTH_SOCK; SSH_AGENT_PID=2827; export SSH_AGENT_PID; echo Agent pid 2827; andrew@zaphod:~$ My guess is that ssh-agent is crashing, but how would I know? What log file would it log to?

TomTom GO & Ubuntu Linux: impersonating a GPRS phone with dund

- by Broam

Background: I've called TomTom support, and they don't support Linux. I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work. However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering. However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4. I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way. Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine. I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure. My Question: I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on? Update: apparently dund is a legacy tool that's going away. What replaces it?

Ubuntu 9.10 Only Sees 244 MB RAM, while BIOS and Windows Sees 1.5 GB

- by nicorellius

I have 1.5 GB of RAM installed on an older Dell, Pentium 4. I just installed Ubuntu 9.1 and the system is only seeing 244 MB of RAM, even though there is 1.5 GB on the system. The BIOS sees all of it. I ran a Knoppix disc and it only saw 25 MB upon booting. I made no particular changes to the installation taht would affect this. I looked through the BIOS and the only setting I could see was the AGP aperture. Not even sure what this is. Anyone know where I went wrong? I also tried moving the memory modules around on the board. Booted with the 1 GB stick, still saw 244 MB. NOTE - This same system, except for the hard drive, had Windows XP running on it. The user who ran it said that the RAM was good and always showed 1.5 GB.

RDP access to DirectAccess Server via DirectAccess

- by crgnz

I have just setup a Win2008R2 DirectAccess server (and also a Win2008R2 Active Directory server). From the Internet I can Remote Desktop login to the AD server, but I cannot RDP into the DirectAccess server. I can PING both servers and get an IPv6 response. (I can RDP to the DirectAccess server from the internal company network) DirectAccess is configured to allow full intranet access. I think I've hit a mental block, the answer will probably be obvious, but I just can't see it.

Ubuntu 12.4 compiz - disable all compiz plugin - empty screen

- by gotqn

A friend of mine has installed on my new machine Ubuntu 10.4 (I have always been windows user and have no experience with Linux). I started to watch some tutorial about how to make 'Rotated Cube' using 'Compiz',but the cube appears in the form of a list (only two slides). I have thought this could be result of my video cards (only two - one from the processor and one from the motherboard) and they can not support this options. Anyway, I have decided to disable all compiz plugins and options because my friend has set some, and I started to think there is some misunderstanding between the plugins. After, that I got only empty screen(no menu, no icons, anything) and can do nothing. How to fix this? EDIT: When I remove the compiz stuffs (from the console), the menu is shown again. Then I install the compiz again (some of the effect are still not working). After restart or log out/in the menu is hidden again. I suppose that there are some settings that I've broken but they are saved somewhere in the system and remove the compiz do not deleted them and as a result they are activated after compiz is installed again and the PC is restarted?

Access to SQL Server when administrator account deleted

- by Shiraz Bhaiji

An interesting situation here. We have a database server, used for testing only, where someone went in and deleted the administrator login. Since this is a test server the was no other admin level login on the server. Is there a way to get access to the server again without reinstalling SQL Server? We do not need the data in the databases, these are droped and recreated everytime the tests are run.

SQL Server High Availability - Mirroring with MSCS?

- by David

I'm looking at options for high-availability for my SQL Server-powered application. The requirements are: HA protection from storage failure. Data accessibility when one of the DB servers is undergoing software updates (e.g. planned outage for Windows Update / SQL Server service-packs). Must not involve much in the way of hardware procurement. The application is an ASP.NET web application. The web application's users have their own database instances. I've seen two main options: SQL Server failover clustering, and SQL Server mirroring. I understand that SQL Server Failover Clustering requires the purchasing of a shared disk array and doesn't offer any protection if the shared storage goes down (so the documentation recommends to set up a Mirroring between two clusters). Database Mirroring seems the cheaper option (as it only requires two database servers and a simple witness box) - but I've heard it doesn't work well when you have a large number of databases. The application I'm developing involves giving each client their own database for their application - there could be hundreds of databases. Setting up the mirroring is no problem thanks to the automation systems we have in place. My final point concerns how failover works with respect to client connections - SQL Server Failover Clustering uses MSCS which means that the cluster is invisible to clients - a connection attempt might fail during the failover, but a simple reconnect will have it working again. However mirroring, as far as I know, requires that the client be aware of the mirrored partners: if the client cannot connect to the primary server then it tries the secondary server. I'm wondering how this work with respect to Connection Pooling in ASP.NET applications - does the client connection failovering mean that there's a potential 2-second (assuming 2000ms TCP timeout policy) pause when the connection pool tries the primary server on every connection attempt? I read somewhere that Mirroring can be used on top of MSCS which means that the client does not need to be aware of mirroring (so there wouldn't be any potential delays during connection, and also that no changes would need to be made to the client, not even the connection string) - however I'm finding it hard to get documentation or white papers on this approach. But if true, then it means the best method is then Mirroring (for HA) with MSCS (for client ignorance and connection performance). ...but how does this scale to a server instance that might contain hundreds of mirrored databases?

How to eliminate overscan on Ubuntu HTPC

- by Norman Ramsey

I'm using an Ubuntu box with Nvidia graphics card as an HTPC. My HDTV is a Sony Bravia KDS-R50XBR1; this is a rear-projection unit with many inputs. I am using the HDMI input. I'm using the proprietary Nvidia drivers and they recognize the 1080x1920 resolution just fine. The display is a little fuzzy but at 50 inches it's perfect for movies. My problem is that the TV has three overscan settings, and none of them reduces overscan to zero. When I was using dual-screen this was fine, but I'm moving to where the TV is my only screen, and the Gnome panels are not visible because of the overscan. I'd like to figure out how to eliminate the overscan, without trying to scale my 1080p content down to 920p or something ridiculous like that. Ideally there would be some scurvy trick, perhaps involving the TV service menu, to get rid of the overscan on the TV side. Or I could move the Gnome panels, but I still would be missing the edges of my movies. Suggestions most welcome.

Patching Synaptics Driver In Ubuntu

- by danben

I've got an HP Envy with the new Synaptics Clickpad - the device is not supported out of the box by Ubuntu, so I downloaded this patch (https://patchwork.kernel.org/patch/67335/), applied it to synaptics.c in the linux kernel source, rebuilt the kernel and booted from it. Nothing changed. I'm new to Linux and don't know much about driver configuration; how can I check that the newly-produced synaptics.o file is actually being used somewhere? Or if it is obvious, what step did I leave out? Separately, I tried following the instructions in this thread: http://georgia.ubuntuforums.org/showpost.php?p=8989185&postcount=11 There, someone posted the patch along with a Makefile and instructions for installation. When I followed those, my mouse stopped working altogether. Not desirable, but at least I know it had some effect. The Makefile is posted below; I get the gist of what it's doing, but don't have enough knowledge to figure out why it would cause the device to stop responding entirely. obj-m := psmouse.o psmouse-objs := psmouse-base.o synaptics.o psmouse-$(CONFIG_MOUSE_PS2_ALPS) += alps.o psmouse-$(CONFIG_MOUSE_PS2_ELANTECH) += elantech.o psmouse-$(CONFIG_MOUSE_PS2_OLPC) += hgpk.o psmouse-$(CONFIG_MOUSE_PS2_LOGIPS2PP) += logips2pp.o psmouse-$(CONFIG_MOUSE_PS2_LIFEBOOK) += lifebook.o psmouse-$(CONFIG_MOUSE_PS2_TRACKPOINT) += trackpoint.o psmouse-$(CONFIG_MOUSE_PS2_TOUCHKIT) += touchkit_ps2.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules install: @cp psmouse.ko /lib/modules/$(shell uname -r)/kernel/drivers/input/mouse/

Where is vmlinux on my Ubuntu installation?

- by Jason Baker

I'm trying to work with starting up oprofile, and I'm running into a problem at this step: opcontrol --vmlinux=/path/to/vmlinux Ubuntu has no package called vmlinux, and when I do a locate vmlinux, I get a lot of files: /usr/src/linux-headers-2.6.28-14/arch/h8300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-14/arch/m68k/kernel/vmlinux-std.lds /usr/src/linux-headers-2.6.28-14/arch/m68k/kernel/vmlinux-sun3.lds /usr/src/linux-headers-2.6.28-14/arch/mn10300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-14/arch/sh/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-14/arch/x86/boot/compressed/vmlinux_32.lds /usr/src/linux-headers-2.6.28-14/arch/x86/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-14/include/asm-generic/vmlinux.lds.h /usr/src/linux-headers-2.6.28-15/arch/h8300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-15/arch/m68k/kernel/vmlinux-std.lds /usr/src/linux-headers-2.6.28-15/arch/m68k/kernel/vmlinux-sun3.lds /usr/src/linux-headers-2.6.28-15/arch/mn10300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-15/arch/sh/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-15/arch/x86/boot/compressed/vmlinux_32.lds /usr/src/linux-headers-2.6.28-15/arch/x86/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-15/include/asm-generic/vmlinux.lds.h /usr/src/linux-headers-2.6.28-16/arch/h8300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-16/arch/m68k/kernel/vmlinux-std.lds /usr/src/linux-headers-2.6.28-16/arch/m68k/kernel/vmlinux-sun3.lds /usr/src/linux-headers-2.6.28-16/arch/mn10300/boot/compressed/vmlinux.lds /usr/src/linux-headers-2.6.28-16/arch/sh/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-16/arch/x86/boot/compressed/vmlinux_32.lds /usr/src/linux-headers-2.6.28-16/arch/x86/boot/compressed/vmlinux_64.lds /usr/src/linux-headers-2.6.28-16/include/asm-generic/vmlinux.lds.h Which one of these is the one I'm looking for?

I'm deploying an example SQL CLR stored procedure which has a SQL CLR type as parameter using Visual Studio 2008 and menu Project -> Deploy. public partial class StoredProcedures { [Microsoft.SqlServer.Server.SqlProcedure] public static void TakeTariff(TariffInfo tariffInfo) { } } public class TariffInfo { public SqlDecimal Amount { get; private set; } } but getting next strange error: The default schema does not exist. How can I fix that? My user was created this way: CREATE USER myUser FOR LOGIN myLogin_mod WITH DEFAULT_SCHEMA = mySchema

How to wake from screensaver directly to the login screen in Ubuntu

- by torbengb

(a.k.a. How to switch users without entering password, part II) (see part I) I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). Part of this was answered in my earlier question which helped me get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?

Re-starting SQL Server and OS restarting

- by rem

Some manipulation with SQL Server require re-starting SQL Server after that. If we restart operation system, does this always mean that we restart SQL Server also (it seems evident that it is so, but just in case I ask to be sure)? Or there could be situation when we should do it explicitely for example by context menu choosing "Restart" in SQL Server Configuration Manager? I.e. could it be necessary for something to restart SQL Server while OS is working?

Exporting Environment Variables in Ubuntu Linux

- by stanigator

I know many people have asked about environment variables before, but I am having a hard time dealing with these paths while ensuring I don't mess around with the original settings. How would you go about executing these commands in Ubuntu in terms of environment variables? Thanks in advance! Please put /home/stanley/Downloads/ns-allinone-2.34/bin:/home/stanley/Downloads/ns-allinone-2.34/tcl8.4.18/unix:/home/stanley/Downloads/ns-allinone-2.34/tk8.4.18/unix into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph. IMPORTANT NOTICES: (1) You MUST put /home/stanley/Downloads/ns-allinone-2.34/otcl-1.13, /home/stanley/Downloads/ns-allinone-2.34/lib, into your LD_LIBRARY_PATH environment variable. If it complains about X libraries, add path to your X libraries into LD_LIBRARY_PATH. If you are using csh, you can set it like: setenv LD_LIBRARY_PATH If you are using sh, you can set it like: export LD_LIBRARY_PATH= (2) You MUST put /home/stanley/Downloads/ns-allinone-2.34/tcl8.4.18/library into your TCL_LIBRARY environmental variable. Otherwise ns/nam will complain during startup.
