Zdraveite,

  Poluchih prez izminalia mesec dve pisma s vyprosi okolo scponly i po-
specialno okolo choroot-vaneto na potrebiteli v RedHat 8.0/9. Iavno
problema go niama v drugi distribucii (ili pone nikoi ne se e oplakal).

  Pyrviat problem zapochva s izpylnenieto na scripta setup_chroot.sh.
Scriptyt ne mozhe da nameri programata /usr/bin/useradd. Otvorete faila
i namerete slednia segment:

<p>USE_PW=0;
if [ x/usr/sbin/useradd = x ]; then
       USE_PW=1;
else 
    if [ x = x ]; then
       echo "this script requires the program useradd or pw to add your"
       fail "chrooted scponly user."
    fi
fi

i go preobrazuvaite taka:

USE_PW=1;
#if [ x/usr/sbin/useradd = x ]; then
#       USE_PW=1;
#else 
#    if [ x = x ]; then
#       echo "this script requires the program useradd or pw to add your"
#       fail "chrooted scponly user."
#    fi
#fi

Ima i oshte edin problem predi da se startira scripta, v koito sa naneseni
tezi popravki. Scriptyt ne iska da izgrazhda subirectorii. Naprimer toi ne
izgrazhda /chrooted_user_dir/usr/kerberos, a syshto taka i
/chrooted_user_dir/usr/kerberos/lib. Tiah traibva da si gi syzdadete sami!

Sled tova spokoino mozhete da startirate scripta:

bash setup_chroot.sh

i da napravite chroot directoria na syotvetnia potrebitel. 

Ako sprete samo dotuk, shte ustanovite, che usera, koito e 
chrootnat ne mozhe chrez sftp ili WinSCP da kopira failove i directorii.
Za da se otstrani tozi problem traibva da se napravi edin hityr trik. Da se
kopira sydyrzhanieto na directoriata /chrooted_user_dir/usr/kerberos/lib
v /chrooted_user_dir/lib (niama da obiasniavam zashto..prosto go napravete).
Razbira se.. mozhe da se napraviat i symlinkove (relativni).

  Tova e vsichko. Mislia, che shte byde polezno da dosta hora.

   Pozdravi
    Beco
