Get 7.2 and you will have ext3 Linux file system which is supposedly better. The 7.1 has the same ext2 as 6.0. Maybe some IDE drivers are better, but not much. You should have waited a month longer {:-)} As to ftp and telnet... They know what they are doing... You should not use ftp and telnet. You should use scp and ssh. ============================================================= If you use ftp and telnet, and you are not a guru, the hackers will shred your computer to pieces in no time... (and you will also be eaten alive). Just do man ssh and man scp and you will have known... But if you absolutely have to: Log in as root: cd /etc/rc.d/init.d chkconfig --del iptables chkconfig --del ipchains ./iptables stop ./ipchains stop cd /etc/xinetd.d vi wu-ftpd change: disable = yes to disable = no vi telent change: disable = yes to disable = no reboot the machine. Then it will probably still not work, since I forgot about something (:-)}. Just give some person, who knows Linux and whom you trust, a root password and he/she will fix it for you {:-)}. > > Thanks in advance for suggestions. > > Ulrike Salzner > =================================================================== > > Dr. Ulrike Salzner > Associate Professor > Department of Chemistry Tel.: (312) 290-2122 > Bilkent University Fax.: (312) 266-5097 > 06533 Bilkent, Ankara e-mail: salzner@fen.bilkent.edu.tr > Turkey > > ==================================================================== > Jan K.
