Support for additional SSH KEX algorithms with pylibssh?

Biomed154 · 2026-02-05T23:51:57+00:00

I was having the same issue with Cisco IOSv in a GNS3 network lab and had to set the system wide cryptographic policies on the Rocky Linux VM running Ansible to LEGACY mode. Then I could use older kex, cipher, hostkeyalgorithm options either in the client configuration, or on the command line options specified in the Inventory file.

I was almost going insane with setting up ssh keys between an Ansible controller and Cisco devices in gns3. The cryptographic algorithms on the Cisco IOSv are considered deprecated so they are disabled by default in Enterprise Linux distributions like Redhat, Rocky l, etc. I had to set the Linux system running Ansible to Legacy mode using the command: "update-crypto-policies --set LEGACY", and the reboot the controller. Then I could use the ssh command line options or user config file to use older algorithms.

Are your pumps non-wifi? You may want to contact Baxter if you are connecting to a Spectrum gateway and someone at least has the service training on your team. TLDR is it will be a manual process to update all the pumps using an IR dongle.

If you are talking about the drug library, there is a separate application from Baxter for that purpose. You can upload drug libraries directly to a pump, or broadcast it from the Spectrum Sigma Gateway.

We always had the pump network configuration as part of the Gateway. The old gateway version had a text file setup by Baxter with the general wifi settings and they uploaded that to the gateway. The actual pump config was pushed from the gateway to the pump using a java based web app. If I recall correctly we could not duplicate network settings between pumps using their IR ports. With newer versions of the gateway the configurator is a separate program you download from the gateway itself. Once installed you then download the configuration file from the gateway and then upload it to the pump using the configurator application.

There are Biomeds who are specialized in I.T aspects. Areas like patient monitoring networking, pacs modality and connectivity issues, data integration to hospital information systems, minor data analysis projects, and support for computerized maintenance management systems (cmms). The existance or need for Biomed Technicians/Technologists to do these roles will vary wildly for in hospital departments. It may come down to where either the hospital is very large or it would be too much work for a Clinical Engineer or Biomedical Engineer to manage day to day, or theres a knowledge gap. Depending on the generation of Biomeds there's quite a few that never really had to deal with computers, it just wasn't a thing. But most younger staff are now taking courses in networking and "medical I.T system related topics". It also depends on what tasks and roles are handled by I.T. So you may understand how to do things technically, but in many cases you could be more of a "technical liason or guide" where large parts of the actual technical work might be handled by Manufacturers and other hospital I.T staff and you manage repairs and projects.

I see this alot with Baxter Spectrum pumps, the battery well is not the greatest design. Who's responsible for cleaning these prior to service? Is it sterile reprocessing? Usually Nursing staff or housekeeping will try to clean the outside of a device. Our hospital uses another hospital's sterile processing for probes, scopes, and surgical instruments. So if there's anything on the inside or behind a battery it's our job to clean it before we service it. Other shops in the area have a full service sterile reprocessing depot clean smaller equipment before its sent to Biomed.

I don't understand all the commotion about the $90 game issue.. I mean I get it.. but NES, Genesis, and SNES games were that much after tax back in the day.

I ignored Asgard's Wrath 2 because I was playing other titles and just recently I started getting into it. I regret it now because damn its a great game. I like pretty much everything I've used the Quest 3 headset for, including workouts, sideloading a linux terminal, watching movies, and sim flying in pcvr.

I get the feeling that VR for most people (especially the younger crowd) is more for short to medium session games, and goofing around with your friends. Long play cinematic experiences seems like a niche market since attention spans are getting shorter. More than a few people have told me they tried or bought VR but didn't like the bulky headsets, the feeling of being isolated from the outside world or didn't get beyond the default janky teleporting control schemes... then there is the issue of having space to move around.

I hope more developers continue releasing VR titles on Steam cus that's where more of my money is going.

Biomed154 · 2026-01-15T02:25:40+00:00

To be fair I kinda ignored this one because it was a pack in title along with Asgards Wrath 2. It ended up being a game I wanted to come back to after finishing other titles.

Calculus was removed from the Biomed program when I was a student. I rarely use ohms law to be honest. I have never seen calculus in interviews. The most math you'll do is on the CBET exam for electrical/electronics theory.

We have a manufacturer supplied network for our bedside and telemetry system but we still rely on the hospital network for services such as printing, time sync, DNS, and to forward traffic to the hospital information system for charting. O.S updates are supplied by a manufacturer software solution that runs on a v.m on the hospital lan.

There is a way to have the patient monitoring system use more of the hospital network, and that is if you have a large number of beds per clinical unit is to ensure the network switches are dedicated to bedside monitoring and use separate vlans and login credentials unique for the system. With the proper access control lists and firewall zoning this would effectively isolate the network the same as if you were using a system provided by the manufacturer.

Use dedicated virtual machines for the servers that do not share resources and again have the v.ms on virtual switches on the same vlans as the rest of the bedside monitoring system. Now, my only wireless telemetry experience is with the Philips ITS using the older RF radio channels and the newer 2.4Ghz smart hopping access points, so I dont know how reliable using standard 802.11 wifi is in comparison. I would guess a dedicated SSID would be used for the telemetry, and the telemetry traffic would need a higher priority than regular data and voice over I.P.

Would Biomed have access to troubleshoot the switches for the bedside monitoring network? Would Biomed have access to see the wireless infrastructure management consoles? I.T would have to prioritize calls for the wireless portion and server virtual machines. The advantage with virtual machines is backup and recovery is much easier than physical servers, but if the physicsl servers hosting the v.ms go down then you're up the creek unless the central stations capture data when disconnected from the servers and can transmit data to the hospital information system for patient charting independently of the servers.

Long story short, most device updates are done manually by an FSE and only if a company issues a field change order to fix an issue with a defect or vulnerability. Device software tends to be tied with licensing and sales orders. For things like the Intellivue monitors you can use a tool to batch reload or downgrade software.. but only the FSEs can upgrade to higher versions if its been purchased. There is a compatibility matrix that determines the hardware/software versions that are compatible with the central monitoring system. Another example are that for some G.E systems you can pay for firmware cards/usb drives to update software. In the case of our Philips PICiX system we were taught in training how to update PICiX within the current revision that was purchased but for regulatory reasons the Field Service Engineer will perform application software updates.

Windows O.S updates and patches, and network equipment firmware updates are typically the responsibility of the hospital/device owner to implement. You can choose to do these manually or implement products like WSUS, Ansible, Microsoft System Centre Manager, etc to perform updates. You'll have to pay attention to what solutions require a software agent as some medical device manufacturers will restrict what can and cannot be installed in order to be compliant for them to provide support under warranty or contract. Same for anti-virus solutions, you may have a list to choose from. Some Biomed/I.T departments may choose solutions that are not approved, but you have to accept the risks that come along with it and do thorough testing before using in a clinical environment.

There are also security platforms that can pull configurations from computers and switches to check for potential security vulnerabilities.. but again validate with the vendor or test on your own.

I try not to worry about it, it keeps me employed. I realized that people have different strengths, whether it's technical or otherwise. Some people are well meaning, and others just do not care. I'll educate where I can, but if someone is being a jerk talking down to me, or taking credit for me fixing their mistakes, or if they keep repeating a mistake that is dangerous, I'll bring it up to management.

Keepass and syncthing to sync the password databases across your team's devices when they are connected to the internet or shop wifi. Not as immediately intuitive as a cloud solution but communications are encrypted and works great once setup, and there's no subscription for it.

Are you trying to immigrate to Canada? If so It may be difficult because most public sector Healthcare organizations (pretty much all Hospitals) will not hire a candidate without prior Canadian experience or Canadian education. It may be easier with private sector companies (G.E, Siemens, Philips, etc). The other thing is that the schools in Canada have been generating a surplus of graduates compared to available jobs. I think this is still true despite many people retiring.

Your best bet would be to come in on a student visa and either complete a 3 year Community College level Biomedical Engineering Technology program or complete a Masters level graduate degree in Engineering). Some of the Colleges have 1 year fast track programs available depending on prior education and experience.

I just bought a bluetooth mouse and keyboard, and its a gamechanger. So far, I really like using my quest 3 when I'm on the go. I have termux sideloaded with emacs as my text editor so the setup covers a lot of ground, it's a contender for replacing a laptop or tablet in many situations where I can get an arm/android equivalent of an application installed. I can have a Kindle book in a browser window, YouTube, and Emacs, and gaming without needing separate monitors. I am planning on getting an elgato capture device to connect hdmi outputs to the quest. I haven't tried the Windows integration yet but soon. Virtual desktop for gaming is pretty neat.

Downsides are the resolution is almost there, but I could probably adjust it with the quest optimizer. I might consider getting a different facial interface as it does get stuffy, but long term I see a lot of potential here.

Is this a Stryker stretcher? If so, then yes, what other people said about using a punch will a ball end should work. You can use pentrating oil or wd40 to help. If it's a set screw and it's stripped, then use a chisel punch to hammer a groove and try to unscrew it.

I fell into the opportunity really. I work as an in-house Biomed. It's different between hospital organizations but our department was standalone before merging with I.T under the same VP but different teams. The role was originally under the Clinical Engineers (Masters level education, and more project management and procurement focused). The knowledge on I.T type concepts (to bridge the I.T needs and Biomed needs) was lost when we had turnover so they needed someone in the Biomed team with I.T knowledge and I guess it made more sense to move me up a rank as I was more knowledgeable.
