I followed [URL] to install and use Cisco VPN to connect to my office network. After importing the .pcf file, I am able to connect without any issues. However, once the connection is established, I am not able to either browse the internet or open any intranet sites. If I do ifconfig, I do not get a office IP however the tunnel IP shows up correctly. I am not sure what the issue is.

I did a forum search and too much came up that was not the answer I was looking for. I have only Linux devices at work and I was wondering how do Linux Administrators connect to Cisco devices via serial console cable. Cisco recommends 'Hyper Terminal' which was a Windows add-on applications licensed to XP. I think Vista and 7 no longer have the license to use Hyper Terminal. Regardless I don't have any versions of Windows and would like to use a serial cable from Com port 1 to the console port on the device. I can't use SSH since some devices don't support SSH and or I have to do a password recovery.

I am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.

View 3 Replies View RelatedI have just installed Ubuntu 11.04 and the Cisco VPN client with :
apt-get install network-manager-vpnc
I have imported the PCF provided by my employer into the GUI. The group password also seems ok, when I login to the VPN server, I am provided with the "VPN Login message". (On Windoze, I get an Ok/Cancel popup with the same message). In Ubuntu, I don't get to click "Ok" but it looks like I'm connected properly. The /var/log/syslog file contains numerous static routes added, 30 or so. After the Login Message, I see the couple of line:

Jul 8 12:40:52 ubuntu02 NetworkManager[630]: <info> VPN connection 'VPN to my network' (IP Config Get) complete.
I get an IP from the external network correctly as well:

However, I cannot ping any of the machine on the remote network. None of the network services seems to be accessible. Why the machines on the VPN are not accessible?
I just installed a fresh copy of 11.2 I use networkmanager and the cisco vpn plugin (not the cisco client). I create a vpn profile and connect to it. The icon shows a connection has been established, but I have no network connectivity. In the /var/log/NetworkManager file, I see this

I have a new install of an OpenSuse 11.3 server and I do not see the IPSec Support option when I use Yast to set that I up. I have the firewall setup with 2 interfaces, one external and one internal and that is all working fine. When I connect via my laptop and connect in via a Cisco IPSec VPN, I get connected, but no traffic goes through.
I did search through the forums, but I don't see any hits related to the issue I'm facing. I installed the ipsec-tools, but I am still not seeing the IPSec Support in the firewall section of Yast that I see noted on many Google Searches. Is there a package or something configuration that is needed to get IPSec Support for VPN setup?

I am attempting to setup a network to network VPN tunnel between our main office and a temporary location. This location need full VPN access back to the main office's network.Anyhow we have spent about 3 solid days attempting to make this work without any great success. Here is our network scheme for these two devices.
Network A (Main Office) (OpenBSD using isakmpd)
Network: 172.16.8.0/24
External IP: 1.1.1.1 (obviously not the real IP)[code].....
Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.
Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.
I m nokia mobile to connect to internet in 11.2 configured it all in n/w manager with phone number *99#

I'm having some trouble connecting to the wireless network here at home. The PC has a Linksys WMP600N wireless network card, which works fine under several versions of Windows. In Opensuse however, I cannot get it to find the network. Even though my laptop is right next to it, which has perfect connection to the network. The router is a Linksys WRT610N.
I've tried running iwconfig and iwlist scan in the terminal, but the scan returns no results and iwconfig indicates it does not have a connection to a network. I've turned off IPv6 as I read this can sometimes cause issues. I've also tried issuing the computer a static IP address, figuring the DHCP might be causing problems, but all to no avail.

I live in Japan and am trying to print to a network printer (Richo Ipsio C411 PS). Couldn't find the ppd in the foomatic database. At my previous school, I had no problems printing to the printers on the network once I found the ppd. A few months ago, I transfered to a new site. Unfortunately, when I send a print job on the network here, the printer just gives a Japanese message that says "command error." I've tried other printers on the network (all different models of the Ipsio).
I went to the Japanese Ricoh website and it recommended a generic printer ppd. I downloaded that, but it didn't work. Then I got the ppd off of the windows driver CD and tried that. Again, no success. I have no idea what I'm doing (obvious, but should be noted) or how to get this started. I also tried 2 versions of Ubuntu -- I'm running 8.04 and 10.04.
Attached are copies of the ppd files if it helps.
In fc10 & fc11 everything worked well with vpnc.
With fc12 vpnc starts allows me to connect to my work site then everything works fine til I try and start a remote desktop connections to a windows client use tsclient. All I get is a blackscreen and my laptop is hung.
At work without the vpnc it works fine if I start the vpnc from nm it performs the exact same way and I get the blackscreen.
I have disable selinux.I also disabled the firewall
there was another gentlemen on here with the same issue.
The only way out is a hard reboot and there are no messages in the logs that say there were any problems.
Small office... 20-30 computers all windows based. xp/vista/windows 7. 3 Servers running ubuntu 10.04... 1 domain controller, and two file servers with samba. We want to be able to login once in the morning, and then not have to worry about users/passwords at all throughout the day. So I was thinking that I could setup a PDC and then make the two filservers both BDC's and use ldap to authenticate everything. Would this even work out? and is there a better way to do it?
View 9 Replies View RelatedI am looking for some advice on how best to lock down our office network to keep our employee's from wasting time on sites like facebook and ...... This will be my first time setting up a server as a gateway in a production environment so I thought I should get some suggestions on what the best packages would be to do this.
I essentially need to lock down our network so that i can monitor what everyone is doing on the Internet and block it if needed. it doesn't have to be web based or have a bunch of gui's, im fine with command line, configs and log files, but it would be nice.
I'm interested in commercial products as well as long as they are linux based.
I am wanting to setup an office network consisting of three computers and one server. We already have the equipment ready with Vista Business pre-installed on the computers. I want to be able to create a network which allows users to use any machine as this will reduce downtime should a machine break. Also I would like user's files to be held centrally on the server which makes backups easier.
The most important element here is data backup. As like most businesses we are moving away from paper and using the computers to store important records such as customer information. If this data were to be lost, the business would come to a complete halt.
I have been looking at the idea of installing a Microsoft Small Business Server as it would be nice to have centralised control of the machines. However the cost would be over 800 which can not be justified for three machines and five users. Therefore I am turning to Linux for a alternative solution. I have previously used CentOS and Ubuntu for home use but never really gained much knowledge or experience of either.
It is my understanding that Samba can act as a Primary Domain Controller, which if I'm not mistaken is where it handles the network logins and profiles. Is this correct? I have come across many samba tutorials online but whats confusing is they are all different. Some of the tutorials involve using Kerberos and OpenLDAP. Do I need to learn about either of these? What do they do and what benefit will they bring?
Finally, I see Samba 4 is in development and is likely to bring a lot of new features which aren't available in Samba 3. Is this worth waiting for because I don't want to be upgrading everything again 6 months down the road?
So I've been asked to install a file/printer server and, possibly, inet proxy for a small office (5 PCs). My concern is: There are:4 PCs on XP x32 1 PC on Win7 x642 Printers, one of them with a scanner Some buisness software they use does not cope with win7.Had hard time installing additional x64 drivers for printer (which are obsolete by now, I guess). Network runs on a simple router which is connected to internet. For now they have been using simple sharing of C: folders, which had freaked my out a bit.
So..Despite XP being old and a presence of x64 machine on the network, do I:install x64 server edition install x32 one What additional software, besides Samba and printer/scanner drivers, I will need to handle both architectures? I have rather basic understanding of how servers work, i.e. I run samba, apt-cacher, torrents on my home network.
