1. First of all, it may be that the wireless router has not turned on the DHCP function. Go to the wireless router management page and find DHCP on the left.
2. Or manually set the IP in the wireless network connection of the notebook. Specifically, it is the same IP segment of the router.
3. Another possibility is that the router does not dial. Go into the router and check carefully to see if there is an account and password set at the WAN port, and if there is anything wrong.
How to access the virtual user in ftp of linux?
Add ftp users in linux and set corresponding permissions. The operation steps are as follows: 1. Environment: ftp is vsftp.
The restricted user name is test. The restricted path is /home/test2. Create a user under root: useradd-d/home/testtest// Add a user test. And set the home directory of the test user to /home/testpasswdtest// and set the password for the test. 3. Change the permission setting corresponding to the user: usermod-s/sbin/nologintest// to restrict user testing from telnet. Only ftpusermod-s/sbin/bashtest// user test can return to normal. Usermod-d/testtest// Change the home directory of user test to /test4, and restrict users' access to /home/test. You cannot access other paths. Modify/etc/vsftpd/vsftpd.conf as follows: chroot _ list _ enable = yes//Restrict access to your own directory # (Default Follows) chroot _ list _ file =/etc/vsftpd/ Vsftpd. ch root _ list Edit the vsftpd.chroot _ list file, add restricted users, and change one line of configuration file for each user name. Don't forget to restart the vsftpd server #/etc/init.d/vsftpdrestart5. Users are allowed to change their passwords if necessary, but they don't have the right to log on to the system remotely: usermod-s/usr/bin/passwdtest/.
