Using plog, I see that the connect script is always failing. Using pppstats indicates nothing is being sent or received. ttyS0 looks okay in setserial (I think). Luckily, my host has a removable hard drive. When I remove the Hardy disk and use my Solaris 10 x86 disk (without touching any h/w) the connection works properly and the device on the other end of my serial cable responds correctly. The only difference with the Solaris configuration is that it has a 'noident' option as well as those above.
I have a problem with programming serial port lines. my issue is that i must toggle and read single lines like rts and cts. but my program stops at the line when i open the port. here my sampe:
Code: int port; int i; port = open("/dev/ttyS0", O_RDWR);
[Code].....
when I start the program it hangs on the open-function. I have tried ps with grep for ttyS0 but there is nothig found. Why hangs this function and gives me no error?
If I use ttyS1, it works. where is the problem and why I can't get an error?
CentOS 5 on a DSEB-DG motherboard. I am having trouble communicating with my APC UPS on /dev/ttyS0.
What I do know: UPS and cables are ok they work ok on my other server CentOS on a Intel S3210SH M/B Comparing the serial ports in the Hardware browser I notice that the Working system (Intel) is listed as such
Code:
The non working system lists
Code:
So I can see why the system does not work.
What I do NOT know: How can I correct this problem. Do I need to re-install the drivers? if so HOW.
We are running CentOS 5.3 on a Logic Supply PT109, a ruggedized PC. For some reason the serial ports don't work when the IRQ is configured (i.e. setting IRQ to 0 makes it work, but performance suffers with the polling).
I've used minicom, picocom, and plain old cat and echo talk to the port both with a loopback connector and to another PC. statserial shows the control lines changing as I change the various settings and connect the loopback connector. I am confident that the hardware is fine as DOS diagnostics show the COMx ports working with various baud rates. I have tried changing the IRQ from the default of 11 to 3 and 4, turning flow control on/off, and tried another PT109.
strace shows data being written, but none being received, so my theories are either the interrupts aren't being generated (doubtful since the ports tested okay with DOS) or the serial driver isn't handling the interrupt. The serial handler shows up in /proc/interrupts when the port is opened. The interrupt counts do go up slowly, but not in response to activity that I can correlate:
I tried to finally set-up surround sound on my Ubuntu 10.04 machine and i was successful in doing so after a while of changing settings and tinkering. After doing so though, i was later in the day not able to get into the Pulseaudio Volume Control, therefore, everything is stuck where it is and i can't change anything. When i try to open Pulseaudio Volume Control i get the error message, Connection failed, Connection refused. My programs still play sound and i can control the sound of the programs through the programs, but i cant control the sound of the sorround sound now and my main sound bar only affects my stereo speakers, not the surround ones.
I believe this may have happened after the random disk check on restart, but i can't 100% confirm that and i'm not even sure if they are related. I still have sound, but i have no way to control the volume of my entire system at once. I did some looking around online and saw that others are having or had the same issue, and it was through different versions of Linux also. somehow reset everything so i can access PAVC and start over . I also tried steps listed in another thread here on the same topic, but they weren't working and it also seemed to be for older Ubuntu versions.
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
I am running an Ubuntu Server on a VirtualBox VM running on my windows machine. So I've created a self-signed certificate using the following tutorial: [URL]
From this tutorial I'm left with 3 files: server.key server.csr server.crt
Then I found this very similar tutorial that has an extra bit on installing the certificates in apache: [URL] So I followed it's instructions which boil down to this:
[Code]...
So I'm thinking this should work now. However in Chrome I get: SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. IE8 gives me a typical "Internet Explorer cannot display the webpage" Note that [URL] fails while [URL] works fine, so it's definitely something in my ssl setup I'm thinking.
It is most certainly my fault but I am now without a sound volume control and it does not show up in the add to panel.What can I do here? Does your icon have code that that I can use or can I find the file somewhere and create a link? Alsa mixer works ok and nothing is muted and I have sound so as to play music. The Internet connection and the power connection icons also don't appear.
I'm trying to do a SSH connection between my home and work PC both machines are running ubuntu 10.04. I have read all the comunity documentation at [URL] from Work PC. I went on to the web site what is my ip address and noted down the number, From Home i opened a terminal and typed: pnig (ip address). to which their was no reply, now i'm assuming i need to configure the works router to except connection requests, is this Correct?
Also what information do i need from my works network and how do i get it? I understand that I need the routers expernal ip address, but how do i referiance a specified computer after that address? What program do i use in ubunu and how is that information applied to it?
I have just installed ubuntu 10 on a thinkpad t410. At first everything worked swimmingly, INCLUDING the wireless. After about five minutes, the wireless stopped working, in that it seemed to think it was still connected but pinging didn't work. I've now restarted several times, and each time I restart, the wireless works for about 1 minute, then stops working. If I try to disconnect and reconnect it will not reconnect (until I restart, that is).
iwconfig shows the correct ESSID and ifconfig shows an address, and "connection information" shows a varying percentage of connection.
i am using ubuntu and with all versions i have one pretty anoying problem. My wired connection sometimes lost connection and i can't reconnect for 3-10min. sometime longer. Technically everything is allright. With win7 i never had such problems. Any solutions how to fix this problem?

I am trying to setup multipath with failover policy on openSuSE 11. I have two qla2xxx HBA's installed and they appear to be working. Here is the output of "multipath -l" command
[Code]....
While testing, I pulled one of the two connection to SAN, and the connection failed over to second HBA connection to SAN. When I plug the cable back in, it does not fall back to original connection... It stays in failed state. Also, I noticed that failed disk (sdd disk) comes back as (sdg disk), which is probably why connection does not fall back to original HBA. But, when I run "/sbin/service multipathd restart" sdg disk shows as as enabled in multipath -l...
I got an error while working with NetworkManager in new RHEL6/ Fedora14. I have a ZTE AC 2726 3G wireless modem. i had tried to connect it via NetworkManager . It only requires username and password to connect but the thing is that after putting all the credentials i had checked the option" available to all the user "and while i was trying to save the profile it shows the following error saving connection failed 0 can't write connection type 'cdma'I had google so many times around this error but no better solution is there .
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
[code]....
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
Each time I start up debian -lenny, the network-manager does not automatically connect me to my wireless network. The connection list shows a lot of networks available, but mine is always absent from the list. This means I each time have to go to "Connect to other Wireless Network" in and write in my network name (SSID) and password (PWA2 Personal). Then is connects nicely and everything works fine until next time I boot
I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.
I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.
I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)
vsftpd not working on my CentOS system. I tried logging in using FileZilla but the error message was: Connection attempt failed with "ECONNREFUSED - Connection refused by server".
I can make a connection to the vpn server, the connection starts, but nothing happens! My IP address remains the same as previous! There is nothing added to my Knetworkmanager, I'm a beginner I should use a pcf file for my vpn connection. I use it properly, I'm sure because the connection starts and an icon is added to my panel and remains until I disconnect.
I checked it via ifconfig -a, the last part (which is for vpn) is:
When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
The situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?
