Questions about enabling ssh and vnc on redhat 5


Recommended Posts

hello

I have some qs about enabling vnc and ssh on linux redhat 5

Have vnc installed and running

Correct vlan and network ip , dns , gw , mask

firewall turned off but still unable to ping , ssh and connect to vnc

What else to check and what to configure ? Please advise

Thanks

Redhat 5? I'm assuming you mean red hat enterprise and not the old red hat system as there was no red hat 5, it was 6.2.

If you can't ping it then you've either disabled ping commands in the kernel (/etc/sysctl.conf) or you've messed up with networking, check everything over because if you can't ping it when you should be able to, then VNC/SSH will never work because you've got no connectivity to it.

^ agreed if you have firewall off on the linux box and you can not ping it - points to networking issue in general. Once you can ping the box, then if vnc and or ssh doesn't work we can troubleshoot that - but you have to be able to verify connectivity first.

Are the devices on the same segment, you mention vlan - so what is routing traffic between the vlans? More than likely you have issue there or firewall between your vlans blocking the traffic you want.

As to RH 5, not sure what n_k is talking about - there was a RH 5, quite some time ago - I use to run it back in the Day ;)

The RH enterprise line did not come about until later, RHEL 5 was released in 2007

So yeah it would be helpful to be specific what your running. But if its 5 be it old RH or even RHEL -- its OLD ;) Why are you running such an old version? Yes RHEL 5 is still under support. But sounds like this is a newer instal if your just now trying to get ssh and vnc working, so why pick such an old version?

edit: So you can still get it here

I got the boot.img booted on my esxi box, so I might try and get it running just for fun ;)

Hello Mr BudMan :)

iptables is disabled

all services are enabled

nothing should be blocking the connectivity between ports

i was able to ping first before i turned off the enforced security ( as i remember )

will check and update the thread

Thanks ;)

Well what was the networking issue? Was it a firewall rule? What?

If you can ping and ssh, then you have something blocking the access - be it firewall on client, host or between? Or you don't have it listening on the host? Or your doing it wrong ;) Ie wrong port, etc.

    • A rotten article full of handwaving of anti-consumer practices. Aside from the fact that no, not even close to every piece of major software collects information about its users, ethical developers make such telemetry opt-in and allow it to be completely disabled. To use KDE Plasma as an example, you're shown a greeter upon first boot that gives users the option to send the developers telemetry, with the default being off and 'off' actually meaning off. Windows 10 has never offered that capability - only a promise that Microsoft will slurp up less of your data if you spend time tweaking 50 different privacy settings. There is still absolutely no way to completely opt out of sending Microsoft telemetry in any version of Windows 10 (or 11, naturally). Even using group policy in Enterprise editions only allows you to reduce telemetry to the bare minimum. Home-focused editions don't even get that option. Articles like this dismissing user privacy concerns as "FUD" are a part of the reason Microsoft felt confident enough to go so much further with Windows 11. I guess you get what you deserve in that respect. Personally, I finally made the move to Linux after 15 years or so of dabbling with it, but never really considering a permanent switch. Enjoy your bright, shiny Windows future. You asked for it, after all.
    • Microsoft shares Defender update for new Windows 11/10 ISO installs by Sayan Sen Aside from new Windows setup and recovery updates, Microsoft has also published a new Defender update for Windows 11/10/Server installation images this week. This update package is necessary as a Windows installation image may contain old, outdated anti-malware definitions and software binaries. Aside from better security, these updates can also provide improved performance benefits in some cases. When a new Windows installation is set up, there may be a temporary security risk due to outdated Microsoft Defender protection in the OS installation images. This happens because the antimalware software included in these images might not be up to date. Thus Microsoft says that these updated definitions essentially help close this protection gap. Microsoft delivered the latest security definitions for Windows images via security intelligence update version 1.431.54.0. The Defender package version is also the same. It applies to Windows 11, Windows 10 (Enterprise, Pro, and Home editions), Windows Server 2022, Windows Server 2019, and Windows Server 2016. Microsoft writes: From Microsoft's security bulletin, we learn that the security intelligence update version 1.431.452.0 was released this past week adds threat detections for various backdoor and phishing exploits, trojans, and more. For those wondering, the latest intelligence update is version 1.431.155.0 at the time of writing.
    • Probably.   You'll probably want to see what channels you'd pick up by entering your zip code here... https://www.channelmaster.com/pages/free-tv-channels   With respect to the antenna and box you selected... no idea.  They are both non-brand names and cheap.  So...sure.  I have no idea how that box records...but it's listed as a feature. Also...I have no recommendations.  I haven't recorded from a cable box (ClearQAM) in over 10 years (maybe 20?).  This was Windows Media Center/MythTV days.  My Hauppauge is just collecting dust somewhere in my expansion slot bin.
    • Yea, I tried to do that with my janky WINDOWS MEDIA CENTER Frankenstein, and it failed miserably.
