Linux professional or advanced that is the question?
by S/C Conway 18 Sep '02

18 Sep '02

G'Day, I recieved an email today from RH which provided links for information on RH Advanced server. http://www.redhat.com/software/whichlinux.html is one link to provide some details. I am left with the impression that all the versions of RH I have installed 6.0 to 7.3 were never designed to be used in a company but just for small businesses and individuals. Advanced server is what I need for the enterprise. Wait a minute, I work for a regional telcommunication provider. I suspect our share holders don't consider the company a small business. I fear RH has created a crippled version of Linux, RH 7.3 and a full version, Advanced server. RH7.3 is the shareware version and Advanced server is the full version you pay throught the nose for. My experience with loading Oracle 8i seems to provide some validity for my perceptions. After 20 attempts at loading Oracle 8i on Linux 7.x using three different installation procedures I gave up. I left Oracle running on RH6.2 where everything works. I would really like to get SSH to work on 6.2 but I gave up after the 15 library change! I never did get the Oracle 8i to work completely in 7.x. I did get it to a point I could create a database but not all the tools worked. Towards the end of my database penance it was suggested I use Oracle 9i and it would work! Wait....that product has a both a greater hardware and software requirment. If I read about RH partnerships and key developments, they are all on Advanced server product. Am I getting paranoid? I have pushed to use linux as the alternative O/S. I am now questioning my convictions. I am seeing shades of gate's company. Tech support "oh you didn't purchase the advanced version, I am sorry we can't help you." "we don't support that service in the professional version, you will need a subscription for the Advanced version to get it to work correctly." Can I solicit some opinions? Sean

ntp log file rotation
by Brock Wolfe 17 Sep '02

17 Sep '02

I just configured ntp on a few RH linux hosts and everything appears to be working. To complete the installation I want to rotate the ntp logfile /var/log/ntp. I have looked at a few references and there seems to be disagreement on the best approach: ALTERNATIVE #1: use logrotate with file in /etc/logrotate.d (see code snip below) ALTERNATIVE #2: use ntp.conf "monitor" command "filegen" Are there any suggestions for ntp log file rotations ? FILE: /etc/ntp.conf .... logfile /var/log/ntp ------- [EOF] FILE: /etc/logrotate.d/ntp /var/log/ntp { daily rotate 7 notifempty # ntpd doesn't handle SIGHUP properly copytruncate } [EOF] Brock Wolfe ___________________________________________________________ "The problem is not that there are problems.

the at command
by millward 17 Sep '02

17 Sep '02

I can't get the at command to work. I've tried all kinds of stuff and either it can't find the file, or creates a job in the at que, and then fails to run it. For example: at 2:10pm today < /usr/my_c/showenv showenv is entered as a job in the at que, but never runs. The que is empty after 2:10pm. at -f /my_c/curs/hello 2:10pm today Again, its entered as a job, but when execution time comes all I get is an error message saying it couldn't find the file. Both hello and showenv are C executable programs with root permissions. I'm executing at as root on the command line. I've also tried a simple script called ruff. #!/bin/sh ehco "Hello. This is a Test." I gave ruff chmod 777 ruff Tried to get at to run ruff with at -f /usr/my_c/ruff 3:15pm today It was placed in the at que. I saw it as job 5 using atq. But when the time came, nothing happened and the que emptied. Could someone tell me what I'm doing wrong?

pine 4.44
by Mel Seder 16 Sep '02

My configuration includes the following personal-name=melseder user-domain=yahoo.com I sent a test message to myself (melseder(a)yahoo.com) from within pine. I got the message ok but the from read mel(a)yahoo.com instead of what I wanted which was melseder(a)yahoo.com. Is the personal-name (melseder) and my login (mel) getting mixed up? What can I do to have the from shown as melseder(a)yahoo.com when someone receives pine/sendmail from me? ===== "The sooner you make five thousand mistakes, the sooner you will be able to correct them." - Kimon Nicolaides __________________________________________________ Do you Yahoo!?

startx
by Mel Seder 13 Sep '02

13 Sep '02

The September 2002 Linux Journal (page 26) showed how to tar -xzvf ... su make install a new Window Manager (IceWM). The instructions end with "create a .xinitrc file containing the line exec icewm, and then type startx". When I type startx I get the following ============================================== Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again. When reporting a problem related to a server crash, please send the full server output, not just the last messages. Please report problems to xfree86(a)xfree86.org. xinit: unexpected signal 2. ============================================= I suspect I have to be in the NON GUI mode. I'd like to be able to get to a NON GUI mode so I can start my x server. I'll just be playing with the new Window Manager and have opened up a scratch account to do my playing in. How do I get startx to fire up the x server? ===== "The sooner you make five thousand mistakes, the sooner you will be able to correct them." - Kimon Nicolaides __________________________________________________ Do you Yahoo!?

Re: [TLUG]: ipchicken.com and access by an outside PC
by Mel Seder 07 Sep '02

telnet 192.168.0.254 333 returned the following message; " Unable to connect to remote host: No route to host". So I opened up the User's Guide and page 27 showed "telnet 192.168.0.1 333". I tried that one and was cheerfully greeted with a password prompt which I responded to by pressing the enter key. The heading for the section that the "telnet 192.168.0.1 333" was in was titled changing passwords and I didn't want to muck anything so I typed "quit" at the prompt and exited. Perhaps I could have explored a bit but the chicken in me took over and I didn't go poking around. I began to wonder if I might be better off in the long run to get a new broadband router. I saw one on futureshop.ca that was a D-Link 4 Port 10/100BT Broadband Router for $139.99. The set up I have now is a router and a hub. There are possibly other benefits than making my workspace a little cleaner and more compact but I don't know what they are. The spec sheet on the broadband router mentioned linux support. I don't know what linux support might have meant but I suspect that it was a program to let you get at the router settings for allowing outsiders to get at my PC by allowing traffic on certain ports. I use Shaw Internet as my ISP and way back (maybe four or five years ago) when I got my router a friend who set it up for me poked a "computer/server name?" into the router and since then I've been on the net. Prior to getting the router I was connected to the net until Shaw switched to assigning dynamic IP addresses. My friend said to get a router and that solved the problem for me. By the way I have two dula boot computers, one upstairs and one downstairs thats the reason for the HUB. IIRC from reading posts to the lists Shaw no longer needs that "computer/server name" to be put in the router. Watching my friend hook up the router I observed that it was a painless procedure. Hook up the cable modem to the router and then plug in the cables from the PC's into the HUB. Words like lease and MAC addresses stick in my mind and I was wondering if I will be presented with problems if and when I try replace my current router and hub with a single Broadband Router & Hub combination. I'm not very comfortable with networking as you can probably tell :-) Any comments on any of the above will be welcomed.

ipchicken.com and access by an outside PC
by Mel Seder 07 Sep '02

07 Sep '02

I'm running Red Hat 7.3 (KDE) behind a firewall (a lan fed by a router). I'd like to be able to SSH into my computer from the outside world and wonder what needs to done to get at my machine. When I installed 7.3 I chose the NO firewall option. IPChicken displayed my IP address as it is known to the outside world and Leo Laporte of the Screen Savers TV show on Tech TV mentioned something about DMZ for people behind a firewall. I don't know what he was referring to. Would someone please enlighten me :-) ===== "The sooner you make five thousand mistakes, the sooner you will be able to correct them." - Kimon Nicolaides __________________________________________________ Do You Yahoo!?

MUUG Meeting, Sept 10, 7:30PM -- Network Traffic Monitoring
by gedetil＠cs.umanitoba.ca 03 Sep '02

03 Sep '02

[Posted to man.unix.general and other news groups...] ------ Forwarded Article <al2r7b$8ic$2(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, September 10. The meeting topic for this month is as follows: Network Traffic Monitoring with MRTG and SNMP At the January 9, 2001, meeting on Network Load Tuning, Gilbert Detillieux took us through some of the load and usage monitoring utilities that are available for UNIX, such as MRTG (available online), among others. However, the coverage of MRTG was rather brief, and didn't include any information on how to set it up. In this month's "Mini-HowTo" presentation, Gilbert will take us through MRTG in more detail, including how to set up a configuration file to monitor a network interface, and some of the configuration options that can be used to tune the output. The presentation will also briefly cover setting up SNMP under Linux, so that MRTG can get interface statistics from it, plus (time permitting) some tips on how to secure that setup. The meeting will also include our usual round-table discussion, plus some preliminary discussion on the proposed by-law amendments and the call for nominations for the MUUG board. The group holds its general meetings at 7:30 PM on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our new meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15 PM, so the meeting can start promptly at 7:30 PM. Don't be late, or you may not get in. Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.
