Download Logmein Client
Wisam Ammouri
When you what to access your work computer you connect to the logmein server. The server then tells the client software on your work computer that you want to connect and the client establishes a connection between your home computer->logmein server->work computer.
Previously up to Firefox v.25 there was a LogmeIn extension, which stopped working in v.26. I removed that, but Firefox behaves as if I still have an appropriate extension, and never offers the install of a new one as per the logmein document just mentioned.
Thank you for your advice. On starting the LogMeIn process, there was unfortunately no change, and the push download appeared, was installed but would not start - just as before. I do have a logmein app in the firefox setup config now, that describes it as an app, so that is a step forward.
It is named logmein client.exe and now I know why it 'does not start' - it is because I have win 7 pro, which enabled me to set a group policy preventing execution of anything in appdata\local except what I allow. As soon as I managed to rediscover how I did that (!!) and allowed logmein client.exe, the app now works.
After much testing and trying, I figured out what the problem is. The logmein client installs itself with a cookie. Very important. My FF was set up to delete cookies upon exit. When I leave the cookies alive for the next session, it doesn't require the reinstalling of the logmein client.
About IE11 and Firefox etc, my IT assistant has found this for me -management/logmein-impending-death-browser-plugins If you want a good laugh, read the dozens of highly critical customer posts that are on there. LMI has shot both feet, but is blaming Firefox.
So through Continuum it only gives the web interface. There is no option through them to have the actual application of Logmein. It downloads an individual client for every computer in the system. So it downloads individual sessions each time with different URL's.
I have to manage some windows server by logmein. But I use ubuntu as client... looks that logmein does not work under linux... it's the same for you ?Simply I connect to logmein, I authenticate myself, try to connect.. java giveme some errors..
The problem on OSX is that there are no decent Logmein clients. There is no native Logmein Ignition application for the Mac and using a browser has become painful because of bugs (in Safari) and the use of slow Java (in Chrome). Some of the things I have done to try and solve this problem include:
I'm thinking it may be due to the way the DNS is resolving. I've also got a number of other LogMeIn FQDN objects that LMI uses (logme.in, etc), but I'm focusing on logmein.com as the above settings should be allowing it. I do not have any UTM features such as Application or Web filtering enabled at this time. There is only 1 host on the lan interface, and it's getting IP/DNS settings from the firewall.
Wildcard entries are not allowed for FQDN address labels. Since it's port 80/443 traffic, you may have better luck crafting a wildcard url filter for *.logmein.com -- add that to your main web filter profile (that's is covering your main web traffic policy). Set the url filter to allow.
Result is the same, no connectivity and all traffic to logmein.com is being denied. The log and debug outputs show that the traffic is failing the policy check, which to me means that the traffic is not matching the rule. I just can't see what could be wrong with the rule in question.
I'm thinking that the LogMeIn client software on the test host is trying to connect using an IP rather than FQDN. Would this cause the traffic to fail the policy check, despite the IP being assigned to the logmein.com domain?
Personally, I'd would use a wildcard url filter (not FortiGuard web services) for what you are trying to accomplish. Since your dilldown log shows the client trying to connect via HTTP/HTTPS, I don't see how it wouldn't work. (Of course, I am assuming actual web traffic and not a port 80/443 data "tunnel".)
Regarding IP lookups for FQDN addresses -- I too was wondering about this since most of our clients are in remote areas with very slow satellite linkups. Never found an actual official answer (of course I merely did a curiously check). I just ended up playing around with the cache-ttl values (from the CLI) for key FQDNs.
FQDN Firewall Address Object simply looks up the FQDN and substitutes the IPs as the object. Any time a client gets a different IP back it will fall outside the policy. Any time the client tries to go to one of the other many addresses owned by servers used by facebook or youtube, that don't fall within the IPs resolved by www.facebook.com, it will fall outside the policy. FQDN address objects are NOT intended as a webfilter and you cannot specify *.facebook.com as an FQDN Address object. How do you do an nslookup for that? Answer is you can't.
Under Security Appliance>Firewall we had a Layer 7 firewall rule setup to Deny P2P - BitTorrent. This rule was blocking any Logmein traffic coming from the outside and was resulting in disconnection issues from the Logmein client. When I removed the Layer 7 firewall rule above the issue subsided. Figured I'd give everyone a heads up and I'd also be interested in any dialog regarding effective prevention of P2P traffic on your networks. Seems like the current Layer 7 implementation blocks a lot of legitimate traffic.

Hamachi became a LogMeIn product after the acquisition of Applied Networking Inc. in 2006.[2][4][5][6] It is currently available as a production version for Microsoft Windows and macOS, as a beta version for Linux, and as a system-VPN-based client compatible with Android and iOS.[7]
Hamachi is a proprietary centrally-managed VPN system, consisting of the server cluster managed by the vendor of the system and the client software, which is installed on end-user devices.Client software adds a virtual network interface to a computer, and it is used for intercepting outbound as well as injecting inbound VPN traffic. Outbound traffic sent by the operating system to this interface is delivered to the client software, which encrypts and authenticates it and then sends it to the destination VPN peer over a specially initiated UDP connection. Hamachi currently handles tunneling of IP traffic including broadcasts and multicast. The Windows version also recognizes and tunnels IPX traffic.
Each client establishes and maintains a control connection to the server cluster. When the connection is established, the client goes through a login sequence, followed by the discovery process and state synchronization. The login step authenticates the client to the server and vice versa. The discovery is used to determine the topology of the client's Internet connection, specifically to detect the presence of NAT and firewall devices on its route to the Internet. The synchronization step brings a client's view of its private networks in sync with other members of these networks.
When a member of a network goes online or offline, the server instructs other network peers to either establish or tear down tunnels to the former. When establishing tunnels between the peers, Hamachi uses a server-assisted NAT traversal technique, similar to UDP hole punching. Detailed information on how it works has not been made public. This process does not work on certain combinations of NAT devices, requiring the user to explicitly set up a port forward. Additionally 1.0 series of client software are capable of relaying traffic through vendor-maintained 'relay servers'.
In the event of unexpectedly losing a connection to the server, the client retains all its tunnels and starts actively checking their status. When the server unexpectedly loses client's connection, it informs client's peers about the fact and expects them to also start liveliness checks. This enables Hamachi tunnels to withstand transient network problems on the route between the client and the server as well as short periods of complete server unavailability.Some Hamachi clients also get closed port on other clients, which cannot be repaired by port forwarding.
Each Hamachi client is normally assigned an IP address when it logs into the system for the first time. To avoid conflicting with existing private networks on the client side the normal private IP address blocks 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 are not used.
The IP address assigned to the Hamachi client is henceforth associated with the client's public crypto key. As long as the client retains its key, it can log into the system and use this IP address. Hamachi creates a single broadcast domain between all clients. This makes it possible to use LAN protocols that rely on IP broadcasts for discovery and announcement services over Hamachi networks.
In addition to building a secure gateway between the client and host computer, LogMeIn provides two further layers of security: TLS and LogMeIn Intrusion Filters. TLS (transport layer security) provides its own two checks to ensure your data has not changed in transit: record sequence numbering and message authentication codes. Mismatching keys means your data has been tampered with, and the transfer will fail. The LogMeIn Intrusion Filter has three components: IP address, denial of service, and authentication. These three filters ensure that bad actors are not connecting through an unknown IP address, hitting your site with an excessive number of connect requests, or trying to guess passwords through a high number of random tests. Each of these acts are common hacking techniques that LogMeIn guards against.
