I am unable to connect to the Internet in lucid via a proxy server using apt-get or synaptic. Opera & firefox connects to the internet fine with the proxy setting.
I have tried the following solutions:
1) set proxy setting using systems|preferences|network proxy
2) editing ~/.bashrc & /etc/.bashrc
3) creating a /etc/apt/apt.conf file.
4) putting the proxy setting in synaptic
For the proxy setting I have used the both the verbose name as well as the ip address. There is no logon requirements for the proxy server. Either formats work in the browsers.
I have a weird issue where all of the machines in my office can all connect to our web server, either via DNS or using the server IP directly. However, on my machine, which is using the same network IP as the rest of the office and I know it's not being blacklisted, I can't access the server at all via SSH or web or mail. I'm the only machine running Linux, I've flushed the network cache using nscd, but this made no difference. Can anyone think of what might be going on here?
I have a dynamic IP connection. so i got hostname on [URL]. Now i want to configure a ftp server with that. I am choosing following options in the network configuration wizard:
1. default transer mode: passive 2. use server's external ip instead 3. get external ip address from the following address: XXXXXX.dyndns.org 4. ask opearting system for a port 5. test result:
I install one server in my system(linux 5.0) and accessing that server through the 127.0.0.1 private ip address(lo). While i connect to a remote server for validating registry it gives me the error and unable to connect to remote server. here some of the files i give here in below to know my system network configuration
I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains). The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
I have configured Sendmail client to send mail to outside network ( Within local domain ), but i am unable to send any mail as i am getting the following error,
[root@cclx10 mail]# cat test |sendmail -v abhilash-o.padmanabhan@hp.com abhilash-o.padmanabhan@hp.com... Connecting to [127.0.0.1] via relay... abhilash-o.padmanabhan@hp.com... Deferred: Connection refused by [127.0.0.1]
I have the following configuration in my "/etc/sendmail.cf" file
# SMTP daemon options O DaemonPortOptions=Port=smtp,Addr=15.146.237.113, Name=MTA
And netstat is showing that sendmail is listening on Port 25 on the IP address which is mentioned.
I've installed centos 5 on an old computer with success and it works great.I can access the web server hosted on the centos server from any computer on the wireless and wired local network. I can also use ssh (putty) and nx client from any computer on the local network (wired and wireless) to access the centos server.On the wireless router I've configured a port forwarding to the wireless network interface on the centos server. I can access the centos server from the outside (internet) through this port forwarding both through http and ssh or nx client.MY problem is that I can't access the centos server from the internet through the wired network interface. Any attempt to view a web page or login with ssh or the nx client will timeout.
I keep getting this, ever time I try to map a shared drive on other systems with my small network. 'unable to mount location failed to retrieve list from server'. This used to work. Main System UNBUNTU 10.10, GNOME ver. 2.32 Sys2 Windows XP Pro, SP3 Sys3 Windows XP Home SP3 [code]....
Mine is used as a server for the above, and also for me to work on. For some reason, I keep getting permission failure. Setting up a share on sys2. sys3, sys4, sys5 can see and read it. My main sys cannot. None of the systems can see the Main one & the main one cannot read any of the others.

I use F10 at home and while away from work on my laptop. Recently I could get the VPN sorted out ( I can now connect to the vpn (ppp0) server at work from home or anywhere else). I am trying to mount a windows folder that is on the work server on my F10 box at home through the VPN connection that is first established.What I know about the windws server
servername sharename username password
When I try this
sudo mount -t cifs //pxxxx/home/abcd /mnt/dir/ -o username=abcd,password=xxxx
I get this error
mount error: could not resolve address for pxxxx: Name or service not known No ip address specified and hostname not found
I think the VPN connection is established successfully. I have a ppp0 connection under ifconfig with an IP address after vpn connection is established.In windows I just map the network drive (\pxxxxhome) username=abcd, password=xxxx and mount the folder as "abcd on pxxxxhome"
Am using Fedora 15, in which i was able to configure the proxy server and authentication. i confirmed this by configuring web broswer and it works. Now the problem is that i want to deploy it out to other computer system(client) i dont want to use the transparent proxy because the Proxy Authentication will not work. I even tried to configure a DHCP server if it will work but i cant still configure for other computer system to work.
Tried turning firewall off, i tried port forwarding tcp port 22, but it still doesn't work. Also am unable to ping modem over WAN, i can ping the modem locally though. Tech support claims pinging and ssh is not part of the internet so they wont support it in any way.
I am a newbie to linux of 4 weeks. I set up my first web server and it works flawlessly - when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.I have two network interfaces on my server, eth0 (public static IP connected to internet) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1
I added "192.168.1.1 www.server.com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.
HOwever, the server itself only opens website if the address is localhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www.server.com.I do not understand why the record in etc/hosts doesn't point it in the right direction. It seems that when I open address 192.168.1.1 it still gets routed to the external network. I have seen using DNAT to deal with the problem but it didn't work in my case (maybe I didn't do it correctly). I have spent whole evening/night trying to sort it out, it's 4AM now, going to bed frustrated and angry (at myself hahaha). Still like linux very much, won't be going to windows anymore. Please help
My network was running happily with no problems. After clicking "Places," then "Network," I double-clicked "Windows Network." My wife's laptop appeared merrily ready to be clicked. I browsed through and accessed the "Public" folder. Ubuntu auto-mounted the "Public" folder on the Windows Vista machine to the desktop.
THE REASON:I wanted to change the icon to a disk so it would mimic a "mapped" drive like in Windows. I right-clicked the shared folder mounted on the desktop, clicked "Properties," and then clicked the picture of the folder. I then clicked through to "/usr/share/icons/Human/scalable/devices" and selected the "drive-harddisk.svg" icon. The icon changed and I could still browse. I unmounted and re-mounted the folder with no problems, then changed back the disk to the regular folder icon.
THE PROBLEM: After restarting the computer, if I click "Places," then "Network," then double-click "Windows Network," I'm greeted with the following error message: Unable to mount location. Failed to retrieve share list from server.
WORKAROUND: Opening Firefox and typing smb://IP-of-wife's-laptop shows the share list. I can open and access the "Public" folder no problem.
It seems this is a common problem. I used Samba to configure and connect the computer running Ubuntu 11.04 with my Windows Visa workgroup. This is a wired, not wireless, connection.
In Ubuntu, under Network, I can see the name of the other computer (NOVA_MORAI), but when I click, I get the error:
Unable to mount location - Failed to retrieve share list from server
I tried the nmblookup command, here is the output:
eleos@Planet-Morai:~$ nmblookup NOVA_MORAI querying NOVA_MORAI on 192.168.1.255 192.168.1.2 NOVA_MORAI<00> And: eleos@Planet-Morai:~$ nmblookup -A 192.168.1.2
[Code]....
There it it. But when I try the findsmb command, it does not show up.
The error message seems common, but I have been trying solutions all day, and I am still not getting a connection.
I can successfully connect to a remote Windows Computer using Terminal Server Client but I cannot save the profile (Fedora 12).This means I have to enter the details every time I wish to connect. As I have many different remote locations I need to access on a regular basis is there any way to save the profiles?
I have 2 server behind the netgear router on my network . win2k3 and CentOS development server, I have port forarded 80 to win2k3 server which i can access over the internet and is accessable. However I can SSH CentOS machine and portforwarded 8080 and 82 for web access, I can't access via any of the port, browsers says UNABLE TO CONNECT.. there is no firewall in CentOS machine.
My network has several machines on it. They are all connected to a single router. Two of the machines are running Windows Vista, one Windows XP and one Fedora 11. When I go to places.network, I see an icon that says Windows Network. If I click on it, I get the message: Unable to mount location, Failed to retrieve share list from server. When I had Ubuntu running on this machine, I had no problem seeing and connecting to the Windows Vista machine.
I'm having trouble connecting to my freenas server.
It's part of my windows network and when I try to connect to it,I get this message: Unable to mount location,Failed to retrieve share list from server.
Is there something I need to enable on the server or my OS(CIFS or something)?
I've been running a Samba server under RedHat 8 for five years without a hiccup. I want to cut over to a F10 box but cannot get shares accessible. smbclient attempts fail over NT password error. SELinux is disabled. Server is visible on the network. Users require no password access to shared data.
smb.conf follows:
# Samba config file created using SWAT # from UNKNOWN (>) # Date: 2009/06/12 14:15:15
i am not able to port 8080 on my CentOS VPS server.I have followed all the instuctions as mentioned on iptables wiki page.Also I am able to telnet my ip address and port number, But can not access from browser.
I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
I am trying to install either Ubuntu or CentOS server in text mode only. The problem I am having is that the hardware that I am trying to install it on has no vga output, I can only connect to it via console cable. I am able to boot from USB CDROm or flash drive but unfortunately since the hardware does not have a gpu (atleast none that I'm aware of) I am unable to get past the boot screen. If someone can point me in the right direction or know where I would be able to download the text install of either OS, that would be awesome.
I have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.

We're running a sendmail server on a fedora core 9 which we've configured recently. The problem is, the server is working fine but there are some e-mails that enter our server but doesn't get forwarded to the user.

1) I have my Nagios running on the linux box and BMC Remedy Server on the Solaris box. I have simulated a mail from Nagios to be delivered to the Remedy server. But the Remedy Server does not receive it. I even tried snooping on port 25 but nothing has reached the box.
