No, only students and staff at Umeć University can become members.

2. Logging in / the account

2.1 How do I log in from home?

Use an SSH client, see the login page for more information.

2.2 How do I change my password?

To change your password, login on our computers with SSH and then use the command passwd and follow the instructions on screen.

2.3 HELP! I have forgotten my password!

Come visit us on our support.

2.4 Can I get back deleted files?

We take backups each night, so if you're missing a file that you want back then please contact support@acc.umu.se as soon as possible so we can try to restore the file for you.

2.5 What computers can I log into?

You can always log into login.acc.umu.se, this will connect you to one of our servers that are online.
Due to how the key handling works in SSH, this is not optimal. See the login page for more information.

2.6 From what computers can I log into ACC?

You can log into the ACC system from just about any computer connected to the Internet. In order to do this you must have an SSH client.

For more information see http://www.acc.umu.se/help/newbie/login.html.sv.

2.7 Group accounts

See http://www.acc.umu.se/help/newbie/gruppkonton.html (only in Swedish).

2.8 How do I get access to the computer lab?

Visit us on our support.

3. WWW

3.1 Being a member, do I get to have my own homepage?

Sure, you can place your own homepage on ACC. The address will be http://www.acc.umu.se/~username/

For more information, see http://www.acc.umu.se/help/web/index.html.en.

3.2 How much space do I have for my homepage?

You can store up to 16 Gigabytes in total on your ACC user account.

3.3 Why do I get the error message: "Forbidden. You don't have permission to access..." when accessing my HTML-files?

You must set the correct access rights on your HTML files.
Use chmod 755 on directories and cgi-scripts, also chmod 644 on regular files. If you don't feel comfortable using chmod, then type fixchmod, this will take care of the access rights of your web pages for you.

3.4 Can I put up a homepage for my club (i.e sports association) on my ACC account, even though it isn't connected to UmU?

No! It is not allowed to keep sites for external organizations (this according to rules set by SUNET).

3.5 Why doesn't my homepage show up in the member-register ?

The page is updated once every day, so you've got to have some patience.

If you have waited for more than one day and your homepage isn't listed, make sure you have named your main-page index.html and nothing else.

3.6 Why doesn't CGI/SSI work on my page ?

If the www-server lets the CGI-call pass unmodified (ie. you can read text like <!--#include virtual="script.cgi" --> when the page is loaded in a browser), then the page is probably named incorrectly.

HTML-files must have the extension .html (small caps) to enable the www-server to parse them correctly. If you make your pages in a DOS/Windows environment it is common that they are named .HTM or something else.

4. E-mail

4.1 Is there a webmail?

Yes. Our webmail is called Puss and is available from https://puss.acc.umu.se. Use the link marked Log in and log in with your username and password to ACC.

4.2 Which settings should I use?

Here is a short list of the settings that you should use when you're setting up you email program for use with your ACC account:

Please note that the outgoing server should be configured to use authentication. This makes the mail program use your username and password when you're sending email.

4.3 Can I forward my mail to another address(es)?

Sure! Create a file named .forward in your home directory. This file should contain the address or addresses where your mail should be sent. To keep a local copy, this text should be in the file:
\yourusername, name@some.place.else.

If you want to forward your mail to foo@example.org then just log in using Putty/ssh and type:

nano .forward

This loads the nano editor. Then just write the email address that you want to forward to.


Save by pressing Ctrl-X and confirm with Y.

This works on most Unix-systems.

4.4 We need an alias for our group-account

See our help-page for group-accounts.

4.5 How do I filter mail into different folders ?

This is achieved by creating a configuration-file to procmail called .procmailrc in your home-directory. Read the related manpages, namely procmailrc for detailed instructions and procmailex for ready-made examples.
The format of .procmailrc is rather tricky at first, but very powerful when you get a hang of it.

4.6 What is Greylisting?

ACC is using an anti spam/virus technique that is called Greylisting. It means that the first time a triplet sendingcomputer/senderaddress/receiveraddress is seen, our mail server says "please come back later". The next time (if it has waited at least 5 minutes) all such mails will be let through without delay. This means that the first time you get a mail from person X from computer Y, it will be delayed a bit, but all such mails after that will arrive directly. All legitimate mail servers should keep mails until the reciving computer has received the mail, but spammers doesn't do this as it's cheaper to ignore that. They will just move on to the next address in their spam list and try that instead. Mail virus will be limited as well as they will not retry, but just go on and try the next address instead.
As with all anti spam methods there are cases where legitimate mails will be stopped and never arrive, but that should be very rare since even if you are not using greylisting mail servers can say "I'm busy right now, come back later". If the sending server can't handle this, the mail will be lost. If they do, they are also violating the requirements for email servers on the Internet.

What should I do if a mail I want has been stopped?
It could take a little while before the sending server tries again, so wait a little first. If it still doesn't arrive - contact support and we will look into it.

5. FTP

5.1 Why can't I login through FTP?

We have closed down regular FTP since it sends passwords in cleartext, use SCP/SFTP instead. See the file transfer help.
