I can connect to the internet and browse. I'm wired and using DHCP on a Windows network. Updating Ubuntu or downloading programs takes hours for 52MB of updates. Why? I read some articles that mention Network Manager needs to be enabled at the .conf file. Can I edit this using GUI or command line only?
I am a new user of Ubuntu...I am trying to use if for a University project. I have installed Ubuntu under a nice new partition and install was smooth. I am using my Belkin F5D8055 v1 USB adapter to connect to my router. The router registers that the IP 192.168.0.3 has connected (thats the IP assigned to the adapter) however even when trying to ping the router (192.168.0.1), I get no response.
So I just changed my network card settings recently, and I'm now getting no response when I ping the broadcast address for them... the cards are all connected through a switch with IP addresses 192.168.0.x, broadcast 192.168.0.255... ifconfig on all of them shows UP BROADCAST RUNNING MULTICAST, but nobody responds to a broadcast packet. Any thoughts?
EDIT: Pinging each machine individually works fine.
I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.
Trying to get this server to work and abandoned trying to do it with Xubuntu last night and installed Ubuntu server. But now I'm stuck on Samba again as I decided to use the vi editor to edit the smb.conf file and now I can't get out of it.
I am trying to edit my /etc/resolv.conf file while under root. After saving the changes and reboot my computer, file has not changed. I read a thread on chattr and lsattr on this fourm.(see link below) I ran in terminal lsattr /etc/resolv.conf and got the following results:-----------------e- /etc/resolv.confWhat does the dashes and e mean? I thought I would get ----ia------------ /etc/resolv.conf instead, as shown in the link. What am I doing wrong?
I want to edit the file ports.conf to make Apache to listen only to loopback interface as described [URL]... here ,The text extract follows
The Listen directive specifies the port, and optionally the IP address, Apache2 should listen on. If the IP address is not specified,Apache2 will listen on all IP addresses assigned to the machine it runs on. The default value for the Listen directive is 80. Change this to 127.0.0.1:80 to cause Apache2 to listen only on your loopback interface so that it will not be available to the Internet, to (for example) 81 to change the port that it listens on, or leave it as is for normal operation. This directive can be found and changed in its own file, /etc/apache2/ports.conf
But by typing [CODE]sudo vi /etc/apache2/ports.conf [/CODE} and opening the file I am not able to edit the file After going to the Listen Directive I am not able to type 127.0..0.1, Since what I type does not appear on the screen, the Keyboard is not working. How will I be able to edit the ports.conf and other configuration files
I am trying to edit my grub.conf file. I am logged in as root. It says it is a read only file. I have tried to set permission with chmod 777 and also tried through GUI. Using VI it says it's a read only file. Using nano it will not write either. I have two choices on boot up. I want to automatically go to second automatically. First at the moment is CentOS-4 i386 (2.6.9-55.ELsmp) and second is CentOS-4 i386 (2.6.9-55.EL).
I'm trying to set up some shares on this pc and every time I try to edit the /etc/exports file I get this error. I get the same error when I try to edit /boot/grub.conf file or any other files. Does not matter what editor I use. I'm running f14.
I'm interested in learning how to start a wireless connection via the terminal rather than the NetworkManager applet. Every resource I've found on this subject talks about how you need to make a .conf file, then use wpa_supplicant. Is there a way to establish the connection without having to a create any file whatsoever? What are the steps for establishing the connection?
From what I've read, establishing a WEP connection is as simple as calling iwconfig and then dhclient. Are there similar steps for WPA2?
I got a diferent domain. I got a modem-router (192.168.1.254 ) thats connect my computer with apache (192.168.1.68) I got dinamic dns with inadyn to update the ip adress for my domains. My question how to edit the hostname file (/etc/hosts)?
I have a Netopia 3000 Series Internet Gateway [URL] & windows 7(laptop) & ubuntu 9.10. - My laptop connects to it wireless and my ubuntu via ethernet cable. - I am trying to setup file sharing and printing. How do I go about in making them ping each other? the networking side. I logged in the router & check and windows has ip 192.168.100 & ubuntu has 192168.1.2
I have a router with ddwrt on it that runs a DHCP server. What I want to do is only allow people who have pre-determined MAC addresses to get an address to get on my network. That being said I have a VM set up as a DHCP Server. Since doing this I will be setting the dhcp settings on my router to be a forwarder to the VM. Is there a way to allow only static leases in the dhcpd.conf file? I do not just any computer on my network to get an address I want to base it on MAC addresses.
and I have share1 and its subfolder " subshare " the thing i have to do is that, i have 2 assign user1 and user2 to share1 that means user1 and user2 can only access share1 through password and user3 can access only its subfolder "subshare" i have done this upto first level permission of share1 not able to do for its subfolder "subshare"
I run a local apache server, that has some virtual hosts running. Now I want to be able to locally connect to these virtual hosts, but when I try this, it puts www and .com behind the url and says it can't find it. On Windows I know the equivalent, editing the hosts file. Is there something similar in linux?
I set up a virtual bridge for a virtual machine (qemu-kvm) using a qemutap interface:
Code: # brctl show bridge2 8000.0022648a3dcc no eth5 qemutap2 I can ping and ssh to the server ... Then I try to copy (scp) a file (2.8 M) to the server and, near the end, the copy stops and the server stops responding to ping and is not able to ping nothing except itself.
"ifconfig down ; ifconfig up" and the server is on line again.
I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Ping by hostname - there is a 5-6 second delay between each one of the responses:
Ping by IP - the responses come VERY quickly one after the other:
So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.
I have Mandriva One 2009.0 (192.168.1.100) on one box and Mandriva Free 2010.0 (192.168.1.118) on the other. I can ping router (192.168.1.1) from both of these boxes but I can't ping one box to the other and the other way around. What's going on?.
Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.
I recently setup a new Linux server running Fedora 10. For some reason all ping response times are rounded to the nearest 10ms. For example, running the simple command "ping yahoo.com" give the following sample results:
64 bytes from ir1.fp.vip.re1.yahoo.com (22.214.171.124): icmp_seq=12 ttl=57 time=60.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (126.96.36.199): icmp_seq=13 ttl=56 time=50.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (188.8.131.52): icmp_seq=14 ttl=56 time=40.0 ms 64 bytes from ir1.fp.vip.re1.yahoo.com (184.108.40.206): icmp_seq=15 ttl=56 time=50.0 ms
I could post a larger result set but its all the same... every response is rounded to a multiple of 10ms. This wouldn't be a big deal except that the server is running Nagios for monitoring so accurate stats are important. The Nagios check_ping and check_icmp commands are also returning rounded off results. How can I get ping to simply respond with the actual response times rather than a rounded off number?
I am trying to get a Linux (Slackware 13.37) working in a Windows networking environment. The IT support for this organisation does not extend to Linux support, so I'm limited in what help I can get for this.
I'm trying to get to the point where I can get to the internet to download what I need on this Linux machine.
The situation is this (*fictitious addresses used) -My Linux machine uses a fixed IP address (10.100.150.21) My Windows machine uses a DHCP assigned IP address (10.100.150.213)Both Linux and Windows machine are configured to access the gateway server (10.100.150.1)So, I can ping the Linux machine from the Windows machine and vice-versa.I can ping the gateway machine from the Windows machine.I can browse Windows Shares on the network via SMB from the Linux machine.I CANNOT ping the gateway machine from the Linux machine with the Destination Host Unreachable message being the error message.
For actual internet access I need to access a proxy server but since the Linux machine can't even ping the gateway server, it fails to ping the proxy.Now, I have been told the gateway is a HW based router and for Windows machine they use some software for authentication to connect to the network. This software isn't available for Linux, so that's why I've been told to use a fixed IP address.My experience of networking is pretty basic and most of the Linux setup is done via running Slackware's setup program.
I have connected xp and fedora through crossover cable . xp has ip address 192.168.0.1/24 (manually assigned) fedora has 192.168.0.2/24 with default route equal to 192.168.0.1
I can ping fedora from xp computer but i can't able to ping xp from fedora computer.
I have manully edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file with correct subnet mask and ip address because when i tried to give ip address manully in network manager the subnetmask is replaced with gateway address don't know why.
Now i want to share internet through crossover cable . xp is connected to internet through wireless usb adapeter.
I was also having a problem with the Shutdown / Reboot sequence taking ages due to using WiFi, WPA2 and mounting SMB shares. I wasted about 4 hours digging around before I finally realised that the solution involved Upstart. 1. Open a terminal and enter:
Code: sudo gedit /etc/init/network-manager.conf 2. Just below the description line add the following:
Code: pre-stop script /etc/init.d/umountnfs.sh end script
3. Save the script and attempt a restart. I don't know if this will work for everyone, or even what version of Upstart you need for it to work, but it cuts my shutdown time from about 2 mins to about 30 seconds.
Note: This has been working for me about 90% of the time. Occasionally though I see that the script ends prematurely due to the TERM signal and I end up with the 2 minute wait again. I've added the following to the /etc/init/network-manager.conf file:
