I have successfully installed squid proxy server for my college . Then i used proxy authentication for 10 users using htpasswd command in a simple text file with encrypted password. It works fine.
My request is that I have to manage 2000 usernames of students for authentication . How can i do this ?
Is that single text file capable of holding 2000 usernames and password for authentication ?
Is it possible to have the passwd file for svnserve encrypted, rather than store the usernames/passwords in plain text?

These dumps were to tape 000289.
*** A TAPE ERROR OCCURRED: [No more writable valid tape found].
Normally I will load the proper tapes and run the amflush to push stuff from the holding disk to tapes manually. However this time amflush in this case did not help, Amanda immediately responded with an out of tape error again.
Meanwhile I got some errors from dmesg as well

I started a new job and they use LDAP here. I built a new RHEL 5.5 server and configured LDAP. Usernames are recognized but the password is not. I can chown a file to a user name but when I try to login as the user it won't accept the password.I know the password is correct because I can login to any of the old boxes and it accepts the password. I ran authconfig-tui to tell my RHEL box to authenticate to ldap.

I am not able to connect samba server from other linux pc giving error: NT Authentication Failure
But am able to access through anonymous login from linux Same is working fine will all smb users through windows. I am using rhel 5.
I need to setup a way for our Web Developer to login to this particular server to manage the webpages that are hosted. He prefers to use his ftp client/fireftp since he connects to all other servers that way. I can connect via local network but can not seem to connect from my home computer. We have a firebox firewall and we opened port 21. Do we need to open any other ports or just port 21?

View 1 Replies View RelatedWe're syncing users from Active Directory over to our linux LDAP server (Red Hat Directory Server). The user names on the AD side are all written in uppcase letters, which is the company policy.The uppername usernames causes problems when setting up /etc/sudoers, since uppercase words are interpreted as aliases. For example, if I add user KENNETH to a User_Alias (i.e. something like "User_Alias ADMINS = KENNETH"), I will get a warning from visudo which expects KENNETH to be an alias and thus not a username. Despite the warning, sudo does seem to work correctly. But is there a way to tell visudo or sudo that usernames are uppercase, and should not trigger a warning? Or are there other ways to go about this sort of thing?
View 2 Replies View RelatedI have configured a ldap server and trying to login to same ldap server using a ldap user. However, I am not able to login and getting the following in /var/log/secure:

I can see that if I use the ldapsearch with same filter, I am not able to locate the user "ldapu1". However, if I change the filter to (|(objectClass=posixAccount)(uid=ldapu1))", it shows me the ldap user:
[root@redhat5 ~]# ldapsearch -x -b "ou=Users,dc=homeldap,dc=com" -D "cn=Manager,dc=homeldap,dc=com" -W -H "ldap://127.0.0.1/" "(|(objectClass=posixAccount)(uid=ldapu1))"
Enter LDAP Password:
# extended LDIF
# LDAPv3
# base <ou=Users,dc=homeldap,dc=com> with scope subtree
# filter: (|(objectClass=posixAccount)(uid=ldapu1))
# requesting: ALL
# ldapu1, Users, homeldap.com

# search result

Where I have made a mistake?
- Is it necessary to create an account on Linux box and then migrate it to ldap?
- I was just wondering if I can somehow change the default filter from AND to OR at the time of login. I used "pam_filter |objectClass=inetOrgPerson" in ldap.conf.
However, it didn't change the filter.
I have a rather difficult problem. Every time I need root privileges and I am asked to authenticate (i.e. Update Manager, mounting a partition, etc), the password window comes up, shakes and immediately closes, leaving me with no chance to enter a password. What to do?edit: this is NOT the login window, just the little dialog that pops up when you need elevated privileges.

Now the problem is that i want to deploy it out to other computer system(client) i dont want to use the transparent proxy because the Proxy Authentication will not work.
I even tried to configure a DHCP server if it will work but i cant still configure for other computer system to work.

View 1 Replies View RelatedSeismicmike here. My first post. I'll try to be as clear and concise as possible. For the sake of this post, I'm going to use 1.2.3.4 as a place holder for my public IP. On my web server, I would like to be able to access the /var/ftp directory through a web browser. I have successfully done so with Google Chrome, but I cannot access the directory in Firefox or IE. Both FF and IE ask me for authentication but then time out attempting to load the directory.
I suspect that there may be something up with switching to passive mode and/or that this issue may be more with my configuration of Firefox and not with the server (seeing as how Chrome works). Another possibility may be related to SSL. When I connect with FileZilla, I have to use the FTP over Explicit SSL/TLS option in order to connect. In any case I still would like to fix it. I would also like to avoid having to install FireFTP if at all possible.
Steps to reproduce (not that you can without my actual IP =J):
* Open Chrome
* Go to ftp://1.2.3.4
* Enter username
* Enter password

My Update Manager just came on and announced an update for Windows NT/2000 Terminal server. I am only running Ubuntu 10.04 on my system and have no Windows material. Why am I receiving this useless announcement? I have no desire to keep adding useless applications to my HD. Is there any way to delete this item from the Update Manager?

I am running a small ubuntu-server headless machine at home. It is configured with sshd so that I can connect from anywhere (if I have Internet access.)However, there is a thing: I'd like to have good security and disable password authentication, but I also want to be able to connect from a PC that I've never touched before. And no, I'm not prepared to type a 256 bytes password every time I type "sudo ..."
Here is what I thought: I could have a login (pieroxy) that has a moderately strong password and another user (pieroxy-ext) that has a very strong password (100+ chars.) I would use my regular account (pieroxy) whenever I have a key-based authentication and the other one (pieroxy-ext) whenever I have a password-based authentication to do. Then, I'll just su to "pieroxy" and I'm done typing the 100 chars pwd. In order to do that, I would need to be able to configure my machine so that password-based authentication is disabled for all accounts but enabled for my account that has a strong password (pieroxy-ext). Is it possible to disable password-based authentication on a user basis?
