Parametro AuthorizedKeysCommand presente nel file / etc / ssh / sshd_config. Lo script bash che ho chiamato usando questo comando viene chiamato due volte.
Il file di configurazione è il seguente
#RSAAuthentication yes
#PubkeyAuthentication yes
AuthorizedKeysFile %h/.ssh/authorized_keys
AuthorizedKeysCommand /opt/a.sh
AuthorizedKeysCommandRunAs nobody
E lo script di bash che viene chiamato è il seguente:
#!/bin/bash
logger "have fun"
if [ $# -eq 1 ];
then
python /opt/validate_user.py $1
exit $?
fi
Quando vedo i log in / var / log / messages, vedo follwing
May 19 20:07:32 username vagrant: have fun
May 19 20:07:32 username vagrant: have fun
Sto eseguendo CentOS 6.7 e la versione ssh del server è OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013 e del client è OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 e il comando che sto usando è ssh -v [email protected] -p 2222
Anche quando faccio vagrant ssh , lo script viene chiamato una sola volta
Modifica: quando uso il seguente comando ssh [email protected] -p 2200 -o IdentitiesOnly=yes -i /Users/Vivek/new_file_1/.vagrant/machines/default/virtualbox/private_key
quindi lo script viene chiamato una sola volta
log ssh trovato usando ssh -vv
