Juniper SASE secures the workforce with effective security that follows users wherever they go and an AI-optimized network experience. Juniper meets you where you are and takes you where you want to go without breaking the bank or your ops team.
However, each time I log into my corporate network through Mozilla Firefox and attempt to establish a remote desktop connection the following message appears as Network Connect attempts to load, "An error occurred while extracting one of the Network Connect components."
El Capitan does still allow unsigned kernel extension but like Yosemite you have to turn off requiring signed extensions. Wether this alone is sufficient you will have to try as I fortunately in my current job do not have to suffer Java based VPN client software.
I know why they use Java - because it allows an 'easy' way to push the entire VPN client and configuration to clients via a simple webpage but the stupidity of this approach is that it requires installing support for Java in a web-browser which is by far the most insecure thing you can do and I would say is even worse than (gag!) Flash. Because Java is cross-platform it means even Macs are then rendered as vulnerable as Windows PCs.
Due to this Apple do periodically send out updates to their XProtect list which disables Java completely until Oracle issue a new 'fixed' version. This can and has resulted in everybody losing the ability to access for example a Juniper VPN system for several days. The worst case I personally experienced was when Apple disabled Java on a Friday and because of a bank holiday it was a Tuesday before a fixed version from Oracle become available meaning four days downtime.
In case you are wondering what one should use instead, I would suggest using Apple's built-in VPN client. Both iOS9 and El Capitan now support as standard both Cisco IPSec (with certificates), and now IKEv2 (with certificates) clients. One can then push out configurations via a MDM solution. No need for messing about with Java and in theory an end to operating system updates breaking your VPN client each time.
Can you tell me where/how to download the Network Connect client? My client uses it for Windows but doesn't have Mac clients. The Juniper website (juniper.net) makes no mention of it and I'm loath to download it from a 3rd party site. Or doesn't it work that way?
Typically it is made downloadable from the Juniper appliance itself - if the administrator has ticked the option to allow it to be downloaded. This would then allow a web address to download it from. The URL would look something like -cached/nc/NetworkConnect.dmg
The more common way is to also use a web address again accessing your Juniper appliance which then runs a Java applet which automates checking for whether Network Connect is already installed, whether it is the right version and if either is not true downloading and installing Network Connect for you. This all sounds fine and dandy and a clever solution but has one huge flaw - IT REQUIRES ENABLING JAVA IN YOUR WEB-BROWSER. This is by far the most likely means of also exposing your computer to malware. The irony of a security product requiring Java web applet support is staggering. (This is by no means solely a Juniper issue.) A lot of network administrator chose to only enable this method because it also installs the settings as well client software and they sadly appear oblivious to all the Java related issues. (Shudder ?.)
I personally prefer using the built-in VPN client on Mac and iOS and pushing settings via an MDM system. This ensures you are using the VPN client that is part of the relevant operating system and therefore has the best possible chance of being compatible with that operating system and does not require enabling the dreaded Java web-browser support.
Recently my laptop decided it no longer wanted to start. While it was in the Genius Bar, I dug up an old Macbook Pro (called MBP throughout the rest of this post) and began to configure it so I could use it for work. Configuring a different laptop gave me the opportunity to try out some new/updated applications and see if I could find more ways to be productive (I will cover this in a future post). In addition, it brought up some old issues I had experienced and gave me a chance to fix them and document them. In this post, I would like to talk about the problems I experienced attempting to connect to a Juniper Network Connect (called JNC throughout the rest of this post) VPN and how I was able to get it resolved.
On my MBP I use the Chrome web browser (I have an Android phone). One of the first problems I experienced with JNC is that I cannot use it with Chrome as JNC requires a 64-bit web browser and the production version of Chrome is still 32-bit. As such, I typically use Firefox to get on my JNC VPN and then Chrome for everything else.
UPDATE: Well look at that, appears I missed the announcement: Chrome is now 64-bit on Mac and JNC now works through Chrome! Thanks for the tip!
I was confused by this as I had already installed the latest version of Java 8 and the Java test confirmed my browser was working as expected. A quick Google search turned up this post, which suggested installing the Java package available here. Upon doing so and restarting my MBP, the error message was gone.
Next, I was presented with a different error message:
Now you might be wondering why I do not just download the JNC fat client and connect to my VPN that way. While this works, I use a single sign-on (SSO) solution, which allows me to authenticate once in my web browser and then be able to access everything that I need. Using the fat client would require me to authenticate twice. Now technically I have this problem anyway as I need to use Firefox and Chrome, but I was considering moving back to Firefox for a while, but eventually decided against this.
thank you so much. i just bought a new macbook pro and was trying to connect to work using juniper network and encountered the same problem as you did. i changed the safari settings like you suggested and it worked. thanks again.
I spend a lot of time to try to create connect with the Juniper junos pulse VPN using JNC, MSJNC toolsIt works in my home's network env, but failed in company and 3g env, I think its caused by certificate issue.
Here is documentation of a working setup as of Oct 2013 on a target network that requires login via a web page, and they have multiple pages on the portal for different groups, client version 7.1. The vpn client would not start automatically, or complete when manually invoked using ncsvc.
I'm writing this section to explain how I connect to Juniper Network Connect in a more succinct and consolidated manner. Recent versions of Google Chrome block the Java plugin, so it requires a different approach. This method does not use Java and is, personally, a better way.
Instructed in the previous section, you will need to obtaini the REALM and DSID from your Juniper installation. The REALM is found in the login form on the front page of your Juniper site and the DSID can be obtained from your cookies after logging into the site.
Patching the ncsvc binary can disable the route monitoring function, allowing one to change routes as needed manually or by script. Without patching, a route monitor may be in place that will disconnect if routes are changed.
Consider ncsvc gave original default gw has a higher metric, added a second default with a lower metirc, and target vpn resources are on 10.0.0.0 and 170.0.0.0, and a tun0 ip of 10.15.15.15 (besides principal resources, check the vpn network's dns servers etc)
Many of our customers are reporting a dramatic increase in the adoption of Internet of Things (IoT) devices in their enterprise and industrial environments. As of 2023, reports indicate that more than 75 billion IoT devices will be installed by 2025 and that integrating these devices into business processes improves efficiency by 83%.
To remotely manage a network with a mix of large scale IoT, data and voice devices, you need to be able to pinpoint their accurate location, conduct asset tracking and quickly resolve network issues. But in heterogeneous Wi-Fi networks, connecting IoT and mobile data or voice devices can be problematic. For example, delays in data delivery to and from IoT devices often lead to inconsistent or unavailable real-time metrics and packet loss on voice communication mobile devices can lead to poor user experiences.
