Hi all,

sorry but I can't mount the root directory, I receive this message:

mount.nsf: access denied by server while mounting 10.195.2.2:/

Could you check please?

Thanks

CVE-x08u 2018-04-13 15:07:24 UTC #129

same here, when i try to do a "rpcinfo" I get:

Unable to receive: errno 111 (Connection refused)

Good morning,

I still have the same problem (and no one answer me).

Today I have even another one: when I try to scan the 10.195.2.2 with nmap all the ports are filtered:

Can you check?

Thanks

Someone played dirty. Users tend to disrespect free resources. You can try now, It works.

It says no such device, i searched around quite a bit and i am assuming its because im using kali linux through the app store

sudo mount -o nolock -t nfs 10.195.2.2:/ /tmp/nfs

mount.nfs: No such device

Working on the tutorial and doing showmount -e IP address keeps having a timeout error. I saw this was solved earlier but seemed like it was server side

Stuck at showmount -e 10.195.2.2 . Getting a response of: rpc mount export: RPC: Timed out.

I hope the admins can help since maybe someone might have disrespected the free resources again.

showmount -e 10.195.2.2
$ rpc mount export: RPC: Timed out.

Not work. (((

I'm also getting a timeout on the showmount command. I can ping the machine and run nmap tho.

showmount -e 10.195.2.2

rpc mount export: RPC: Timed out

Why?

hello I'm stuck I need help, when I try to execute the command mount -o nfs 10.195.2.2:/ / tmp / nfs

I get as a result: access denied by server while mounting 10.195.2.2:/

Think the server's down again. I've been trying several times while connected to the VPN, but nmap isn't returning anything except:

Starting Nmap 7.70 ( https://nmap.org ) at 2019-03-15 22:30 CDT
Note: Host seems to be down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 3.07 seconds

Thanks

Works now.

It was running, but when I got to the point of mounting the nfs volumes, it originally told me "Permission denied" for a few minutes, then it seemed to crash the server after that.

dev:# mount -o nolock -t nfs 10.195.2.2:/ /tmp/nfs
mount.nfs: access denied by server while mounting 10.195.2.2:/
dev:# ping 10.195.2.2

Sorry for the inconvenience.

Usually there is a rebuild cronjob every 24 hours. It works now.

nmap -sP -PN 10.195.0.0

Nmap scan report for 10.195.0.0
Host is up.

Also, is it 10.195.0.0 or 10.195.2.2?

K3r0sen 2019-03-19 22:57:22 UTC #145

Metasploitable is at 10.195.2.2

Hello,

I'm stuck trying to mount the HD through SSH. Is this because the of tcwrapper on the service? The videos posted on the site look different than this updated level.

thanks for any help
