Dr. Dobb’s Journal in its Linux and open source section is running an article by Emmett Dulaney with 50 Perl questions and answers. The focus is mainly on the knowledge of the language itself with questions like:

In Panther (10.3) and later, the default shell for new accounts is bash (/bin/bash), while in Jaguar and earlier, it was tcsh (/bin/tcsh). If you carried a user account forward from an earlier version of OS X, your default shell is likely the same as it was when the account was created.

Unix is the operating system of our server. Shell Access allows you to telnet in and use various programs already installed there. Some examples are PINE (an easy to use e-mail client), LYNX (web browser), PICO (a text editor), MAIL (a primitive e-mail client), IRC (Internet Relay Chat) and networking tools like NSLOOKUP, WHOIS, FINGER, RWHOIS.

No, generally speaking. But if you can contribute something useful as a volunteer that requires shell access to do it, please ask.

If you want your PHP scripts to be able to write to files in your home directory, you will need to use ACLs (Access Control Lists) to modify your file permissions. If you have a UNIX shell account on the IDS server, you can do this yourself using the setfacl command. See the ACL Howto in the support section of the site for details on setting ACLs. If you don't have a UNIX shell account, then you can send an email to IDS Administration with a request to change the ACLs on your files.

shell [10] chsh Changing the login shell for username Enter the new value, or press return for the default Login Shell [/bin/bash]: Replace /bin/bash with the UNIX shell you would like to use.

Check your current disk space usage; you may be over your quota (See #2 above on how to check your current disk space usage) If you continue to have problems; please contact the support desk at (330) 972-6888 or consult@uakron.edu

First, this is a religious issue if there ever was one, for Unix users. The most popular shells (in no particular order) are the Bourne shell (sh), the Korn shell (ksh), the C shell (csh), the T shell tcsh. There are certainly are intelligent folks that use, and are proponents of, each shell out there. The Korn shell is available with nearly every Unix. It was written by David Korn of AT&T Bell Labs and has been provided with all System V-derived Unix systems since at least the late '80s.

If you don't know whether your computer is running Windows XP or an earlier version of Windows, take the following steps:

A: Login to your shell and type the following: - type ps x - find the PID number of the process - then kill -9 PID number

If you know how to log into your system terminal, you can go to LD-22 and at the REQ prompt, type in "ISS". This will output the release info for the system. Otherwise, you can look at a spare copy of your system diskettes, or pull the one from the system drive to check it and then put it back in. Both types of diskettes will have release info printed on them.

I have noticed that Linux TNOS when compared to Dos TNOS, on the same specification hardware will perform faster. Running TNOS under Unix will allow yourself and your users to take advantage of several Linux/unix services, such as ftp, smtp, telnet, httpd, online muti-user games etc. Using TNOS under Unix you will not run into any memory restictions such as you would with the Dos version. You have no need to worry about what options you compile into your version of TNOS i.e. how large it is.

On Solaris, Java Advanced Imaging complains about lack of access to an X server. This is a manifestation of a JDK bug in which creation of the AWT Toolkit class results in an attempt to open the X display. To work around this problem, either make an X display available to the Java runtime using the DISPLAY environment variable (no windows will appear on the display), or consider running a dummy X server that will satisfy the AWT, such as the Xvfb utility included with the X11R6.4 distribution.

Note that you could always ssh to fox and then run pine directly on fox. This has the advantage of making all the mail operations fast but doesn't work so well in handling attachments (e.g., MS Word documents). Also, if you have a slow connection (e.g., modem), you wouldn't want to use the viewers (e.g., gv or xv) on fox but instead use local viewers (it still will be slow if the attachment is large!). To have Pine access your mail on Unix we'll use imap.

All Gridgen installation CDs contain software for all the platforms Gridgen supports including Unix, Linux, and Windows.

b) If the script must use single quotes, then close-single-quote the script just before the SPECIAL single quote, prefix the single quote with a backslash, and use a 2nd pair of single quotes to finish marking the script. Thus: sed 's/cannot$/can'\''t/g' file a) If possible, put the script in single quotes. You don't need to prefix the double quotes with anything.

kpasswd: Cannot establish a session with the Kerberos administrative server for realm ASC.HPC.MIL. Preauthentication failed. Connection closed by foreign host. Secure Shell (ssh) software developed in Finland by Tatu Ylonen supports secure X-sessions and may be configured to honor user logins based on UNIX passwords, user RSA public keys, host RSA public keys, or Kerberos authentication tickets. Secure Shell fits nicely within the Kerberos/SecurID environment.

Thanks to our carefully developed web based Control Panel and e-mail management system managing your server is as easy as one mouse click. That said, there is even greater flexibility to be had by accessing your server directly on the command shell via SSH and a basic knowledge in Linux or any Unix variant will enhance the Dolphin experience further. We offer training courses for just this purpose, through Positive Skills.

Yes, after installing a telnet daemon on the Windows machine. But, remember each copy of Toolkit is licensed to one machine. If you install it on a server, you must still purchase one license for each client machine.

For example, the Unix shell from the MKS-toolkit. Do you have the SHELL environment set to point to this shell? You can try resetting the SHELL environment variable. If you are using a Unix shell on MS-Windows, you should try to use exuberant ctags that is compiled for Unix-like environments so that exuberant ctags will understand path names with forward slash characters.

To quote the README file: Secure Shell (SSH) is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for rlogin, rsh, and rcp. Additionally, SSH provides secure X connections and secure forwarding of arbitrary TCP connections.

When you start a server normally, the first line of the database server window reports the version number. at a command prompt, where N is your major version, a popup window appears with the version of the server. Or, you can view the version number in the first line of the database server window when you start a server normally. In Windows you can right-click any executable or DLL, and choose Properties and Version to get the version of the file.

Send the command "SHOW LICENSE" to LISTSERV. The last item on the response from LISTSERV is "Build date" -- this should be 26 Feb 1999 or later. If the build date reported by LISTSERV is earlier than this (even if it is reporting to be 1.8d) you should install the latest build.

In the WINLSCP program, pull down the Show menu and select "Version & License". Alternatively, you can use the command line "LSCP SHOW VERSION". The version reported should be 1.1b and the date should be Feb 23 1999 or later.

From the console of your VM login, issue the command "TELL MAILER SHOW VERSION" (this assumes that LMail is running under the MAILER account; if it is not, then issue the command to the user account LMail is running under). The response includes a line indicating the version number. If you are running a Y2K compliant version of LMail, this version number will be 1.2d or later.

When I connect to the VPN I get a message saying my password is recognised but I am not authorized for dialup access. When I enter my login name and password I get the message "Error 800: Unable to establish the VPN connection ...". Whenever I try to log on from home I get the messages 'Unable to locate the server copy of your roaming profile' and 'No local profile therefore using temporary profile'
