Get UUID from VM and ESX

Sometimes one wants to get the relation between a VM from the ESX inventory and from the system.
From ESX:
  # esxcli vm process list
  vm-inventory-name
  ...
  UUID: 56 4d 7c f7 f7 a6 a3 b1-fb 71 cd 3b 3c 34 65 0a

From Linux command line
  $ sudo dmidecode | grep UUID
  UUID: 564D7CF7-F7A6-A3B1-FB71-CD3B3C34650A

This is the relation and it's up to the user to reformat all these outputs.

But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo...

How to make wget, curl and Maven download behind an NTLM Proxy Working on CentOS, behind an NTLM proxy: yum can deal without problem with a NTLM Proxy wget, curl and Maven cannot The solution is to use " cntlm ". " cntlm " is a NTLM client for proxies requiring NTLM authentication. How it works Install "cntlm" Configure "cntlm"  by giving it your credentials by giving it the NTLM Proxy Start "cntlm" deamon (it listens to "127.0.0.1:3128") Configure wget, curl and Maven to use "cntlm" instead of using directly the NTLM Proxy Note: You will have then a kind of 2 stages Proxy : cntlm + the NTLM proxy Configure CNTLM After installing cntlm, the configuration file is in "cntlm.conf". You must have your domain (in the Windows meaning), proxy login and  proxy password. Mine are respectively: rktmb.org, mihamina, 1234abcd (yes, just for the example) You must have you NTLM Proxy Hostnama or IP ...
