Networking :: Error Message - Can't Communicate With Ypbind
Apr 6, 2010
I am trying to set up an NIS client on a Fedora Core 12 64-bit system. The ypbind daemon is running via the /etc/init.d/ypbind script. However, whenever I run the ypwhich command, the following error message appears on-screen:
[code]...
The client has been configured so the domain is set, and the client will broadcast for the first available nis server. The client is on a subnet where there is one nis slave server, so it should bind to that server. One thought that came to mind was the fact the client in question is 64-bit, while the nis slave is 32-bit. Could that cause this problem?

After updates and restart of debian server, my NIS is not functioning. No yptools are working, it cannot find the server. All my commands I issue on the NIS server. When I issue the command yptest, I get:
>>

Test 1: domainname
Configured domainname is "cga.lan"
Test 2: ypbind
Can't communicate with ypbind

I want to communicate between two threads, each belonging to a different process. Iam using message queues for this. I use mq_open()call. I created the queues with the same queue name starting with a '/'. But when I open the queue, the queue ID is different in both the process. What should I do so that both the process have the same queue ID?

I am testing with Suse Linux Enterprise Server 10 in a VMWare environment. I've installed two SLES10 servers, named sles1 and sles2. I can't get the two servers to communicate, even a simple ping won't work. The "Network Adapter" in VMWare is set to "bridged", a setting which has worked fine when installing WinXP in VMWare and connecting to the Internet.Even if I ping sles1 from sles1 (= "pinging myself"), I get the same error message.Only if I ping localhost, I get a proper ping result.What did I do wrong? Did I forget to configure something?

I downloaded and installed a new copy of Fedora 11 last week onto a new computer (hereafter "proximate"). I also have a remote computer without a monitor running an outdated version of Red Hat Linux (hereafter "remote"). To manage the processes on remote graphically, I ssh from proximate into remote; this connection succeeds without incident in transmitting text (including commands) between the two computers; however, the command "gnome-session" returns: (gnome-session:15789): Gtk-WARNING **: cannot open display:
(The numbers apparently represent the process identifier and vary from instance to instance.) A similar warning (and no accompanying graphics) occurs whenever I attempt to start any graphical user interface from remote via ssh from proximate. The issue almost certainly lies with proximate; remote successfully communicated graphics to the ancient box that proximate replaces.
Interestingly, I cannot communicate via ssh from remote to proximate (within a secure shell from proximate to remote). If I execute /usr/sbin/sshd on proximate as root, then I can login, but even then I cannot execute any commands.
Consider the following output:
If I execute ssh -vvv proximate from remote to proximate, then I get a lengthy output that ultimately ends with "debug1: Exit status 254."
What must I do to communicate both text and graphics among my computers?

I have two computers...Ubuntu server and Windows XP client. Both are connected to the internet using Ethernet. I have them connected directly using 1394 to increase speed of large transfers. The internet network and 1394 have different IP address scemes. Internet 192.168... 1394 10.0.0...
I am having problems getting the two computers to communicate with each other. I can ping the server's ip address and and it loops back. Same with the XP's IP address. I can't ping each other.
ifconfig shows my eth0 and eth1 connections are up. The eth1 Link Encap says UNSPEC.(Don't know if that means anything.)

Chili555 where are you?
I am running Ubuntu Release 10.04 (lucid), Kernel Linux 2.6.32-26-generic-pae, GNOME 2.30.2.
I have installed the ASUS USB-N13 according to your advice in previous posts, specifically, in your advice to 828688 Ben.
The dongle seems to be operating as it should. The LED does its flashing at what appears to be the correct time. Wicd also looks correct. Networks are found with good signals shown. Everything looks correct. But when I attempt to connect, "validating authentication" runs for quite some time, and eventually results in a dialogue window stating the communication failed. The required WEP password is entered in the RT2870STA.dat file, and again in the wicd window.
I have entered as much detail in the RT2870STA.dat file as I dare, and believe it to be correct.
ndiswrapper is not installed. Network Manager is uninstalled. Only wicd remains.

I am testing with Suse Linux Enterprise Server 10 in a VMWare environment. I've installed two SLES10 servers, named sles1 and sles2. I can't get the two servers to communicate, even a simple ping won't work. The "Network Adapter" in VMWare is set to "bridged", a setting which has worked fine when installing WinXP in VMWare and connecting to the Internet. I have configured the Network Settings as follows:
SLES1:
-Statically assigned IP Address
-IP-address: 192.168.0.20
-Subnet: 255.255.255.0 (/24)
-Hostname: sles1
Hostname/DNS tab:
-Hostname: sles1
-Domain Name: local
-Name server: blank
Routing tab:
-Default Gateway: 192.168.0.1 (= my router connected to the Internet)
SLES2: same as sles1, with IP 192.168.0.22 and Hostname sles2
With these network settings, the two servers seem totally unable to communciate.
-When I ping sles2 from sles1, I always get the error message: connect: Network is unreachable
-Whatever way I ping, either ping sles2, ping sles2.local, ping 192.168.0.22, whatever, the error message is always the same.
-Even if I ping sles1 from sles1 (= "pinging myself"), I get the same error message.
-Only if I ping localhost, I get a proper ping result.

given my computer is in a network consisting of multiple subnetworks, i.e. there are groups of computers: {192.168.1.1, 192.168.1.2, 192.168.1.3 etc.}, {192.168.2.1, 192.168.2.2, 192.168.2.3 etc.},..., {192.168.254.1, 192.168.254.2, 192.168.254.3 etc.}. My computer is 192.168.1.1. So I can communicate with 192.168.1.2, 192.168.1.3 etc. To communicate with other people I have manually switch to the proper subnetwork and take a new ip, e.g. 192.168.2.1. My question is: Is there any way to be member of all groups and communicate simultaneously with ALL computers? And if not, is there a way to find out (without manually changing the ip address) if computers of other subnetworks are online, so one does not have to change the ip and then look for other computers in the new subnetwork?

In both CentOS 5.5 and FreeBSD 7.4 when I use
Code:
snmpget -v 1 -c public windows_host system.sysDescr.0
I get the remote windows machine system description just fine. But not in ubuntu.
Searching snmp-net FAQ for the erroe message "Unknown Object Identifier", I got this to work around
Code:
snmpget -v 1 -c public 127.0.0.1 SNMPv2-MIB::system.sysDescr.0
But it not worked either.. Searching "MIB" using apt-file search, I installed "snmp-mibs-downloader", and now
Code:
snmpget -v 1 -c public 127.0.0.1 SNMPv2-MIB::system.sysDescr.0
works.. but
Code:
snmpget -v 1 -c public windows_host system.sysDescr.0
still breaks..
Why it works in CentOS and FreeBSD but not in Ubuntu?

One problem has led to another.. I had notebook version 9.10 and it worked OK. I Downloaded 10.04 onto USB and all seemed fine. After upgrade - disaster. I have as Asus Eee PC901.
1. I am in Italy and bought a TIM USB mobile broadband modem - Ubuntu can see the device but nothing happens except a bizzare message with no information at all 'Unable to Open Archive'. I have no idea what that meant nor what I should do to resolve whatever it is, so I went back to my older USB modem which worked under 9.10 - Now even that device does nothing.
2. as a result, Ubuntu software centre does not work, Synaptic Package manager is the same; also update manager.
3. Limited communications are available via the university wireless network. That network requires me to work through their own proxy;port address (with username and password) which I have set up using proxy manager including the username and password. This allows me to carry out web surfing and point to point downloads.
4. Firefox works fine, and it obeys the requirements for registering with the proxy. Thunderbird, evolution, Synaptic, Update manager, Software centre etc all fail because they failed to authenticate with the proxy. They all have been set up to use system proxy. (Also tried direct proxy address;port in each package but no go)
5. The ultimate frustration has come from the direct download of Skype (.deb). Double click and it starts to install then crashes because of numerous dependencies (things like libqtgui4).

I keep getting a "bad password" error message when trying to connect via wpa_supplicant to a wireless network (Apple Time Capsule WPA/WPA2 mixed).
Here's my wpa_supplicant.conf:

The Time Capsule log contains the following error message--

So perhaps the password is somehow getting lost in translation from Ubuntu to the Time Capsule?

We're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.

I have been able (with some hair pulling and gnashing of teeth) to print from outside the LAN to the printer connected via USB to the desktop computer at home, until the last upgrade. The laptop will forst say the printer may not be connected, but eventually (usually) after a while says the job was sent to the printer. The log files on the desktop - serving as the printer server have an error message in cups/error_log that I am not familiar with, and don't believe I have seen before. I am sure if I could decipher that error and figure out how to change the behavior to get rid of it, it would once again work. Printing from within the LAN is a no-brainer as it has been for the last several releases. The error that I get when trying to print outside the LAN (via the internet) is:
cupsdAcceptClient: 12 from <WAN IP>:631 (IPv4) Unable to encrypt connection from <WAN IP> - GnuTLS internal error. I am missing something as far as authentication from the laptop to the desktop. how to fix it.

It's been awhile since I posted anything which is a good sign my install has been working well and I have been able to handle most everything. However, I'm not able to handle this issue. I recently installed F11 and everything went well. But, when trying to see my other computers on the local network, I cannot. I receive this error message: Unable to mount location Failed to receive shared list from server. I understand the message as it is obvious, but do not know how to fix it.

I have been trying to set up a network bridge for the 2 virtual machines installed on my Fedora 14 host PC. I want the VM's to be able to ping each other and have their own "network" in which they can operate/communicate. What is the simplest way to accomplish this? Most of what I have read revolves around turning off NetworkManager, and the following config files:
[code]...
Once these files are configured and the network is restarted, the bridge should work. Is this true? I have been encountering problems with this process, specifically when I try to link a VM to a bridge.
