KDE frustrations, now
by m.roth＠5-cent.us 22 Jul '13

22 Jul '13

So I d/l gqview from where I found the rpm, and installed it. It didn't show in my kde menu, so I did something *really* dumb: I ran the kde menu updater. Now I can't lock my screen. Nothing at all happens. Nothing shows in .xsession-errors, nothing shows in /var/log/messages. I restored all of .kde/share from last night's backup... and the screensaver still doesn't go, and leave->lock screen still doesn't work... *and* gqview is still in my menu, which means that it's stored *somewhere*. I even reinstalled kde, and kde-settings, and some libs, and *still* no screensaver, and gqview's still on my menu. It's got to have been changed somewhere.... Any clues? mark

It CAN be a useful tool for those who don't want a large and complicated program lurking there all the time. i've no clue how other mail handlers are configured, never having done it, but it for sure beats sendmail all hollow if all you want to do is send an occasional mail and can't wrap your mind around its configuration. Of course, no one is requiring you to use it. -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ---------------------------- Do you not know? Have you not heard?

Unless you have perfect control over who is allowed to use this script and what is being sent, it is VERY bad security practice. Replace the bracketed setup stuff (inside <> ) with the appropriate sources and destinations. "$argv" passess the raw data to be transmitted. Depending on what's in the message, you may have to modify the 3rd through 6th lines.

Hey everyone, My company is beginning to look at using SSD drives in our CentOS based servers. Does C5 and C6 support TRIM and other "required" functions for the SSD to operate? Thanks, Andrew Reis Microsoft Certified Technology Specialist CompTIA Network+ Networking/Systems Analyst Webmaster DBMS Inc.

LSI MegaRAID experience...
by John Doe 19 Jul '13

19 Jul '13

Hey, anyone using an LSI MegaRAID experienced "disappearing drives"...? We installed 6 new C6 servers, each with a Supermicro SMC2108 (LSI MegaRAID) controllers and 3 PX-128M5Pro SSDs ( RAID1 + hostswap). 2 weeks (and almost no activity on it, since not in production, apart from installation) later, megacli sees (based on the slot numbers): - on one server: only the 2nd disk of the RAID + the ex-hotswap brought online. NO sign of the first disk, no error message, it just "disapeared"... - on another server: apparently lost 1 of the 2 RAID1 disks and then the second disk of the RAID1... Now I can only see the spare brought online, so lonely... Is it "normal" for megacli to "hide" failed disks? Controller's firmware is the latest. SSDs's firmware are not... will try to flash them. BTW, any tips to flash them through the RAID controller instead of having to remove them all and connect them to a SATA controller...? This is a bit scary... Thx, JD

if /else in expect script
by Tim Dunphy 19 Jul '13

19 Jul '13

I took your suggestion and turned my (ill advised) sudoers bash script into an expect script! It works a lot better this way and is more secure. Because I'm not trying to store a password in a script (which I recognize as a bad idea anyway, I I think I've learned my lesson here). It really works well. But the only thing I'm still trying to figure out is how to put a if statement in there based on success of the last command ($?) before it'll move the new sudoers file in place. I'm verifying it with visudo before attempting to make the move. I'd like to make the final move based on the success/failure of that. Anyway, here's the script: stty -echo send_user -- "Please enter the host: " expect_user -re "(.*)\n" send_user "\n" set host $expect_out(1,string) stty -echo send_user -- "Please enter your username: " expect_user -re "(.*)\n" send_user "\n" set username $expect_out(1,string) stty -echo send_user -- "Please enter your passwd: " expect_user -re "(.*)\n" send_user "\n" set passwd $expect_out(1,string) set timeout -1 spawn ssh -t $host {sudo -S cp /etc/sudoers /tmp/sudoers-template} match_max 100000 expect -exact "\[sudo\] password for $username: " send -- "$passwd\r" expect eof set timeout -1 spawn ssh -t $host {sudo -S rm -f /tmp/sudoers.tmp} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {sudo -S echo '%tekmark_t1 ALL=(root) NOPASSWD: /sbin/service, /bin/rm, /usr/bin/du, /bin/df, /bin/ls, /usr/bin/find, /usr/sbin/tcpdump' > /tmp/sudoers.tmp} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {sudo -S chmod 777 /tmp/sudoers-template} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {cat /tmp/sudoers.tmp | tee -a /tmp/sudoers-template} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {/usr/sbin/visudo -cf /tmp/sudoers-template} match_max 100000 expect eof if { "$?" == 0 } { set timeout -1 spawn ssh -t $host {sudo -S cp /etc/sudoers /tmp/sudoers.bak} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {sudo -S cp /tmp/sudoers-template /etc/sudoers} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {sudo -S /usr/sbin/visudo -cf /etc/sudoers} match_max 100000 expect eof set timeout -1 spawn ssh -t $host {rm -f /tmp/sudoers-template} match_max 100000 expect eof } else { puts "Verification of sudo template failed. Aborting. Process failed" } Pretty simple! Got a suggestion to make this work? If I get that part right, it'll be done.

Re: [CentOS] Frustrated. Java on Centos 6 doesn't give an error message when downloading from a Samsung Galaxy S3
by Scott Robbins 18 Jul '13

18 Jul '13

I didn't keep the email from Ljubomir, so for those of you threading the list on mutt, this will mess up the headers--please accept my apologies. I don't know why I never looked for mtpfs to compile on CentOS--after the link Ljubomir gave, I just downloaded it and compilation was trivial. I think I was always looking for simple-mtpfs, but honestly, I don't remember. Maybe I just never thought of it. At any rate, even with older CentOS libmtp packages, installing mtpfs to /usr/local allows me to mount my S-III. I tried both with and without the udev rules suggested in the link, and it doesn't seem to make a difference. The thing that is essential for me is to run mtp-detect after plugging in the phone. Otherwise, mtpfs will mount the phone, but nothing will show in the directories. If I first run mtp-detect, (though I may have to run it a couple of times before it takes--no apparent link to USB port, and I did make sure phone was unlocked when plugged in) and then mount it with mtpfs, it's fine and works as it does in most other systems. (My way of using is command line, I mount it, usually on /mnt, then with root privilege add or remove files). This was with the phone set to mtp, NOT set to camera. So, many thanks to all who have kept this thread alive as I've been taking the easy way out and just using a more modern system. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6
