can I stop this? can i set a private folder?
I'm running Karmic Koala on my laptop and I'm attempting to connect to my university's secure wireless network. I was directed here by the university's computer help websiteI've followed all the steps, but when I open the wireless network authentication applet and try to browse to my private key, I can't find it. The "chose your private key" window claims to be looking for "DER, PEM, or PKCS#12 private keys (*.der, *.pem, *.p12)," and while my private key file shows up as a .p12 file when I open that location with my file browser, the file doesn't show up when I try and browse to it from the authentication applet. I've attached an image which shows the file in one window, but not in the other f clarification.
View 7 Replies View RelatedI'm currently successfully using the Terminal Server Client to connect to an SBS 2003 server at a remote location. I've been trying to figure out if it's possible to connect to any of the XP machines on the LAN behind it. I currently have to use RWW in IE on a VirtualBox XP machine to do that, and I'd love to be able to get rid of VirtualBox completely.
The server has 2 NICs, one connected to the internet, and the other connected to the LAN. There is only one public IP. The computer I'd most like to connect to has a static, private IP. Anybody done anything like this or have any thoughts on how to get it to work?
My Ubuntu server is now providing routing duties to my network, but I'm having trouble opening ports to my network. I have a DynDNS account, so the IP is always current, but I can't ping even my IP directly.
My network map looks like
Internet > SpeedTouch DSL modem with DHCP > eth1 > Ubuntu > eth0 > LAN
With the modem providing a 192.168.1.xx IP to eth1, I can browse fine. The default gateway is my modem. I switched to the public IP of the modem so I could use iptables for firewall duties, but I was locked out of the internet. No gateway was set when I did that, but eth1 received the public IP of my modem.
How can I use the public IP assigned to eth1?
I has used centos for all my servers but today i have problem with my router.
I install and configure my router/gateway as follows code...
at previous configuration (centos 4x) everything work well with those configuration but when i use centos 5.4
all my client cannot browse the Internet, its only work when i put the ISP dns (221.321.32.15)
i want my client use 192.168.0.1 as DNS.
After years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.

I recently just upgraded from humble Linux user to confused Linux admin of my own virtual Linux server. When I issue the ifconfig command I get following output.
Code:
venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:1.2.3.4 P-t-P:1.2.3.4 Bcast:1.2.3.4 Mask:255.255.255.255
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
The WAN IP of the interface is not really 1.2.3.4 I just changed that IP for security reasons.What I am trying to figure out, is it possible to assign a private IP address to the same interface or can I only have one IP address per interface. I understand I have a mask of /32 so I am not going to be able to subnet the address to create any more addresses, so I assume I am stuck with the WAN IP (public IP) that I have, and just need to deal with it.
The reason I ask this is because I have been reading through several DNS/BIND tutorials/walk-throughs, and a lot of them specify setting up a intranet access with 192.168.1.1 address for the local DNS server, but since I am connecting to the sever via SSH I figure I do not need a private IP address.
I have a linux system which is conencted to a corporate lan and it has internet access to it. But i don think that machine hs any static ip or DNS name. I am able to ssh to that machine within the lan but is it possible to ssh to that machine outside the lan using internet?

View 1 Replies View RelatedWe have to connect one PC in private network (campus) with other PC (mostly a modem in our case)in public network. Connection should be peer to peer like and we have to use C coding for establishing connection between this two systems. Is it possible if we use port forwarding or is there any other way?
View 2 Replies View RelatedThe facts are as follows:
1. I have at work a regular LAN with many PCs, each with a DNS-registered public IP. Therefore I am able to address each of these PCs by their fully-qualified names and, for instance, initiate ssh sessions to any of these computers just by typing "ssh <name_of_machine>" from a terminal.
2. Within the aforementioned LAN I have just created a private network with some clients, which access the LAN through a router (a D-link DIR-825). We have created this private network for many reasons, but most importantly because we need to guarantee that the hosts in this network will remain networked among them even if the LAN goes down for any reason (which unfortunately happens often). But we still need to have access to the hosts in the private network from the LAN.
3. I am able to define port forwarding rules in the router in order to access certain services on the private network's clients. For example. I am able to access (by ssh) hosts "H1" and "H2" on the private network from a client on the LAN by defining rules for forwarding ports "P1" and "P2" on the router's public IP to TCP port 22 on the private IPs of "H1" and "H2", respectively. Then I would access each of these hosts from the LAN by using:
>ssh -p P1 [ip.address.of.router] (for accessing H1) and >ssh -p P2 [ip.address.of.router] (for accessing H2)
4. The problem with the port forwarding approach is that it is not easily scalable. For instance, If I wanted to enable ssh access to each host in the private network, I would have to define a port forwarding rule for each machine, and then REMEMBER all these port rules when initiating a ssh session from the LAN in order to point to the right host. And the problem gets worse when considering more services in addition to ssh.
5. The ideal solution would be to be have a means for addressing each host in the private network individually, in much the same way in which I address the hosts in the LAN (which have DNS-registered names). For instance, in order to access hosts H1 and H2 as in the previous example, i would like to be able to just type
>ssh [name_of_host_H1] (for accessing H1) and >ssh [name_of_host_H2] (for accessing H2)
The bottom line:
I guess I can say that what I need is some kind of combined DNS-ing and routing that allows me to communicate with the hosts in the private network from outside of it in a transparent way.
The question is: what are any possible solutions for accomplishing this? I have searched the web and found stuff about things like VPNs, reverse-proxies and NAT servers, but I really can't understand if any of these could serve to solve my problem (BTW, isn't my router doing some sort of NAT-ing already? could I just add some DNS-ing in some way?)
I run a server that is connected to several other boxes in a private network (192.168.0.0). I have had no problems previously, but upon a reinstall of Debian squeeze I have no connectivity to the private network: a ping of other addresses on that network fail. Ping and connection to outside world is fine. This box is configured similarly to another on this private network which connects successfully. I have quadruple-checked all my basic information. I post my ifconfig below of the malfunctioning device, then the ifconfig for equivalent nic on a box connected succesfully to the private network.
Questions:
1.Could it be a cable problem? (I don't see how since the cables have not been changed I do not believe since my reinstallation).
2. What about the difference in the last lines of eth1 below and eth2 of the successful box. Is it significant that the bad eth1 reads Memory:fc3a0000-fc3c0000
Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
Copying my Thunderbird files to another machine
Two questions:
1. Can I copy xx.default to DVD, its 1.5GB in size, and then merge it into the xx.default of the other machine or try and connect through a crossover cable. I tried to copy onto a flash drive but it did not recognize Inbox.sbd as a folder.
2. How do I manager the existing files in the receiving machine, it has an existing mail account.
Having trouble running backup software to network storage. (Ubuntu 10.04 Beta)
I mounted my network drive (a Netgear Stora) with curlftps (tried several other ways, but this is the only way that works). It shows up like a regular HDD which I can copy files to in the file manager, but when I try running backup software only the folders are copied.
I've tried several backup programs, some based on Rsync, as well as Rsync itself, but they all had problems. Dj Dup kind of worked and was able to copy files (archives), but kept dropping the ethernet connection instead.
While copying a large amount of data between two linux computers I noticed strange behaviour. The network card activity (computer copying the files) would be dormant for 30 second to a minute and then flash rapidly for just 5 second or so. This repeated for the duration of the copying progress (approx 2 hours at a supposedly constant 5-7MB/s).
The share that I was copying to was via SSH using "connect to server" from the GNOME menu. I was expecting the see the network card activity light constantly flash. I wondered if someone could explain this strange behaviour that I have witnessed.

I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).

Whilst files copied to the NFS share are visible to the workstation, they don't appear when using 'ls' on the server. despite the folder owner/ user account on the Microserver and the workstation having the same name and sharing the same UID & GID (1000), copies made from the workstation have a different UID & GID

View 4 Replies View RelatedAfter an upgrade gone wrong my 9.10/10.4 is unbootable and I see no way to fix it.
I can't mount the directory now (LiveCD or chroot), it probably has something to do with the breakage and/or pre-existing ecryptfs issues, as I have both login and mount passphrases.
And it's all on one partition too, so before reinstalling I have to back up. How can I back up the encrypted directory? And can I transplant it to a fresh Ubuntu installation?
cp complains about symlinks, returning 'not permitted', is this normal?
ETA: Now that I look at it from LiveCD .ecryptfs and Private appear as broken symlinks (what do they link to anyway??), but when I tried to copy them while chrooting, they were both accessible directories (though still couldn't mount or copy) - I don't get it.
