email address to system user

Email address to user

My goal is to build a bash script to which I give "mihamina@rktmb.org" and "password" as argument, and then it creates a system user named "mihamina-rktmb-org".

The discribed method requires you to install the package "whois", containing "mkpasswd". Dont ask me why.

At the same time, the script will insert an alias entry into an alias flat file. For "mihamina@rktmb.org", it will insert

 mihamina: mihamina-rktmb-org
in "/etc/exim4/virtual/rktmb.org".

The BASH script

 #!/bin/bash EMAIL=$1 PASS=$2 EXIM_VIRT_DIR="/etc/exim4/virtual/" DOMAINE=$(echo ${EMAIL} | awk -F"@" '{print $2}') LOCALPART=$(echo ${EMAIL} | awk -F"@" '{print $1}') U=$(echo ${EMAIL} | sed 's/\./-/g' | sed 's/@/-/g') CRYPT1_PASS=$(mkpasswd ${PASS}) echo ${EMAIL} echo ${PASS} echo ${DOMAINE} echo ${LOCALPART} echo ${CRYPT1_PASS} echo ${U} useradd  \ --home-dir /home/${U} \ --create-home  \ --password ${CRYPT1_PASS} \ --shell "/bin/bash" ${U} echo "${LOCALPART}:  ${U}" >> ${EXIM_VIRT_DIR}${DOMAINE} invoke-rc.d exim4 restart

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. 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...

wget maven ntlm proxy

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 ...
