nc missing option -z
by Suvayu Ali 02 Nov '16

02 Nov '16

Hi, I used to use netcat to check if a particular host is up or if I have internet connection before I run a few scripts. I would use the -z option in particular. But now I see that has been removed: $ nc -z imap.gmail.com 993 && sync-my-email.sh ncat: invalid option -- 'z' Here is the excerpt from the old manual page: -z Specifies that nc should just scan for listening daemons, without sending any data to them. It is an error to use this option in conjunction with the -l option. Any ideas what happened to it? What can I use as replacement? Thanks for any ideas. -- Suvayu Open source is the future.

Alternatives to Theme Font size changer Firefox plugin?
by Sam Varshavchik 28 Oct '16

28 Oct '16

The popular theme font size changer Firefox plugin, https://addons.mozilla.org/en-US/firefox/addon/theme-font-size-changer/, no longer supports Linux. The default Firefox font size is too small for people with poor eyesight. As far as I can tell, the only thing that official "Firefox themes" do is set a background image for the UI. As Benny Hill would say, biiiiiiiiiiiiig …deal. The top-ranked comment on that extension page suggests hacking "userChrome- example.css" in ~/.mozilla/firefox. $ find ~/.mozilla/firefox -name userChrome-example.css -print $ There goes that idea. Googling around the only other suggestion I found was to hack layout.css.devPixelsPerPx setting in about:config. All that did, apparently, was making the Firefox UI elements themselves bigger, but their font size – the menu and the URL bar – remained exactly the same. Anyone has other suggestions?

Taskbar Panel in Plasma Won't Autohide
by Stephen Morris 10 Oct '16

10 Oct '16

Hi, I am trying to get the Taskbar Panel to autohide, but when I click on the options button in the panel, the left, right and center options are permanently highlighted but seem to function in terms of moving the indicator that reflects which option is active. Also the 'Always Visible', 'Auto Hide', 'Windows can Cover' and 'Windows go Below' options are also permanently highlighted but selecting the 2nd or 3rd option does nothing. It appears these options are highlighted because the colour scheme I am using, which is forget-me-not thinks they are push buttons. Does anyone know why these don't work anymore in Fedora 23? I am using Breeze for the Windows Style and Windows Decorations themes. regards, Steve

Konsole title doesn't change
by Mark Haney 06 Oct '16

06 Oct '16

For some reason, the latest Konsole package (konsole5-16.08.1-1.fc24.x86_64) has stopped updating the hostname on the title bar. I've not changed the profile info in the settings, so this is a bit of a mystery. Anyone else seen this problem? -- Mark Haney ::: Senior Systems Engineer *VIF* *International Education* P.O.

Gnome shell high memory usage
by Earl Ramirez 03 Oct '16

03 Oct '16

Dear All, I don't think this is normal but I will like to know if anyone is experiencing high memory usage from gnome-shell, a week ago was the first time I saw it and to be honest, I can't say it this is something recent of if it has always been this memory hungry. After having my laptop with Fedora 24 on for three days I can see that the memory consumed by gnome-shell is over 2GB and a week ago it was consuming 6GB. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2028 eramirez 20 0 4281540 2.169g 92676 S 10.9 13.9 59:43.98 gnome-shell Is anyone experiencing this problem? -- Kind Regards Earl Ramirez

cups - the printer is not responding
by Angelo Moreschini 02 Oct '16

02 Oct '16

Hi, I have a network printer (that I can see on the computer server browser at localhost:631). When I try to use it, the jobs are not processed... - and I get the message * " the printer is not responding".* I fund this information at link ; https://wiki.archlinux.org/index.php/CUPS/Troubleshooting#All_jobs_are_.22T… ------------------------- All jobs are "The printer is not responding" On networked printers, you should check that the name that CUPS uses as its connection URI resolves to the printer's IP via DNS, e.g. If your printer's connection looks like this: lpd://BRN_020554/BINARY_P1 then the hostname 'BRN_020554' needs to resolve to the printer's IP from the server running CUPS ------------------------ I understand what this means... but I don't know how to accomplice the task*: * * resolve that the IP from the server running CUPS * Any help to do this will be appreciated. Thank you Angelo

RH Linux 5.2, Kernel 2.0.36, SCSI Disks => VM? + Nostalgia . .
by Philip Rhoades 30 Sep '16

30 Sep '16

People, My usual mode of operation when updating OSes is to use a new Hard Disk and install the latest version of the OS (sometimes bleeding edge) and to keep the old disk as an archive drive. So I have a lot of old drives and recently I have been going back through the old SATA and then IDE drives - which has been an interesting archaeological dig! Today I started looking at stuff on this old RH server which was used as a Qmail mail server, EZMLM mailing list manager and a host for a few small web sites. It had not been looked at since the machine had been turned off a long, long time ago - to my surprise it booted up with no problems! Now all I need to do is daisy-chain the Adaptec SCSI controller to an external box with another 4 SCSI drives in it to complete the archaeological exploration. It was a little strange but pleasant looking at all this very old stuff - knowing with hindsight how the users, lists and sites developed after their modest beginnings. I guess I got a bit nostalgic and decided to continue to keep the box (it is the only old box I have that can accommodate the old Adaptec ISA board) but it occurred to me that it would be an interesting exercise to try and virtualise the system - is this possible? - could I create an image from the old 2GB SCSI boot disk and run it as a virtual machine somehow? For the record, my first RH OS was v4.0 - which I used in a commercial environment (we told the boss it was an updated version of UNIX!) - I had used a variety of other distros for fun going back to Slackware and before that Softlanding Linux System (SLS): https://en.wikipedia.org/wiki/Softlanding_Linux_System RH upset me when they took their distro completely commercial and I was cranky for a while but I was very happy when RH finally realised their mistake and createde Fedora Core 1 - which I eagerly lept into! Also, I still have my first-ever (electronic) computer (I had a plastic one when I was kid that had three bits and the clock cycle involved manually pushing and pulling a lever . .) - an Exidy Sorcerer from 1978 which had to have programs and data loaded from audio audio cassettes (!): https://en.wikipedia.org/wiki/Exidy_Sorcerer and my first computer with floppy disks - the luggable Osborne 1 computer. https://en.wikipedia.org/wiki/Osborne_1 I wouldn't be surprised if I could still boot them up as well! . . although it would be a fair bit more messing around . .
