I want to make a script for something, but I'm worried the timeouts on sudo permissions (how you can't got more than 5/10 minutes between sudo commands before needing your password again). Basically, I don't want my script to be redundant and require overseeing for password inputs.
Code:
sudo echo Hello.
sleep 6000
sudo echo This is text. This shows the basis of the problem. I will need to enter my password twice.
Would allowing it to run uninterrupted be as easy as running this theoretical shell script his sudo to begin with?
Just added a new 250g internal-drive in my karmic box, all seems OK and I formatted the partition with Gparted as ext4 but now can't create folders. Unfortunately I don't seem to be able to use a bash shell either, if I type anything in I get no problems until I attempt sudo and then I'm unable to type in a password!
tl;dr - sudo make -> operation not permitted, sudo chown -R 777 * -> operation not permitted on some of the files
I am trying to install a library. Sudo make is getting permission denied on file 1, while using regular make I am getting permission denied on file 2. I have noticed some of the directories in the library are under nobody:nogroup. I tried chown and sudo chown, both didn't work. Sudo chown got permission errors, while chown didn't change ALL the files. (operation not permitted once again) Tried sudo su, and working from there, that also did not work. (permission once again). Using lsattr returned "lsattr: Inappropriate ioctl for device While reading flags on".

I'm running rhel6 64bit. Accidentally I ran % chmod -R 777 /etc and after that I have a problem to do 'su' or 'sudo'. When I did sudo it complained that /etc/sudoers has 777 while it should be 0440. I changed that and also restored right permission for:
Anyway it failed to 'su'. Then I restored back permissions on files in /etc/security and /etc/sysconfig. Still can't do 'su'. Note: I could login from console as root but can't 'su' or 'sudo'. when I do 'su' it gives error: Password: su: incorrect password
I just upgraded to Mepis 11 alpha 2 and am using the gnome desktop. I downloaded the appropriate version of Opera. When I try to install it using dpkg -i, it wont allow it because I do not have permission in either "user" or "root" desktop. I tried to edit sudoers file but it it doesn't seem to work. I can't use sudo because I am not in sudoers file and I cannot edit sudoers file because I do not have sudo permission. When I am in root desktop, I still do not have permission even to read sudoers file. How do I install Opera?
The sudo upgrade of 2010-09-15 modified permissions on /var in my systems, both on 32 and 64 bit. (from 755 to 700) My subversion server stops working after the upgrade, you have to restore the old permissions by hand. I don't inspect how, but I've checked it few times...
Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?
I was having a problem where my server would go unresponsive to it's No-IP redirected name while access via local net IP was unaffected. Access via the No-IP name would usually be restored within 5 minutes or so.
I'm using the linksys wmp300n with ndiswrapper to connect to a belkin wireless router with a static ip (192.168.2.3). The rest of the PCs in the house have .2, .4, and .5 only running windows XP and 7. This one won't stay connected during large file transfers within the network or over the internet in Ubuntu. I made a script to restart ndiswrapper but I have to do it every 2 or 3 min during a file transfer. I can't play online games at all. No ssh sessions for more than a few min... so on and so forth. None of these issues happen in Windows 7 but when it was first installed it had to do something with dhcp before it would stay connected. Windows wouldn't tell me what was going on though. code...
I run a Laptop (Mint 17.1), which is connected to a Debian 8.1 server over a LAN. The systems are connected through a router. Both of them show no problems when working independently and when doing work on the internet. Also, ping works fine (no lost packets, no delays!) from Debian to Mint. However when doing a ping from the Laptop (Mint) to the Debian server, I experience frequent packet losses and timeouts. In fact, a "first" ping may lose the first 20 to 30 "tries". Thereafter, if I repeat pings immediately and quickly one after the other, they might in geral not lose packages or show delays. Ping to and from the router also works perfectly in either direction!
Of course, functions such as ssh or samba-sharing are hampered as well by this behaviour. Also, if I DO in fact manage to connect to the Debian server via ssh, my console (KDE 14) is freuqently "locked" (i.e. - doesn't show my input for a while) but in the end DOES show the characters entered and gets processed o.k. (eg. when doing an "ls"-command). Both systems are at the latest software-level and I just finished installing Debian 8.1. The situation was the same on Debian Wheezy, however.
i'm new to linux so bear with me.we have two servers running in a cluster mode. i disable the cluster so that we could install a new os kernel that was provided by our vendor tumbleweed.So the active server which does not have the upgraded os kernel the version is Linux version 2.6.5-7.283-smp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Wed Nov 29 16:55:53 UTC 2006 for the server which does not have the kernel upgrade, i can mount to netapp mount. however from the server which has it's kernel upgraded, i get a rpc timeout error when i try to mount the drive.
somehow the server which has got the kernel upgrade is trying to use udp. the server goes through a firewall before getting to the netapp server and upd is not allowed.in the fstab entries, i specified tcp,proto=tcp but no matter what values i put in, it's trying to use upd.
We are seeing some dropped SSH connections because of which some of the process are failing . The main likely reason for the connection drops is that both the client and server remains 100% busy during a certain time interval and during that time interval we see those occassional connection closed by the server.
I like my monitor to turn off when I'm not at the computer for more than 10 or 20 minutes or so and it wasn't doing that. I haven't used Linux for years and was used to xorg.conf/x11.conf and xinitrc and such.
So I rediscovered xset is responsible for DPMS settings. xset -q revealed DPMS was off. So I used it and put it in ~/.xinitrc. It didn't work. After some canoodling around I found out about xfce's Session and Startup gui thing. I was using that to run ~/.xinitrc.
When I got to my desktop and did a check with xfce4-terminal by running xset -q it would show DPMS enabled but the values were wrong. 600, 0, 900 to be exact.
After some searching I came across the information that xscreensaver will override DPMS settings as it manages DPMS too. So after more canoodling I found out about xfce's Screensaver preferences dialogue and used that to set my values. The values would immediately be set but the problem is that they are not persistent. If I reboot or log out the values will revert to 600, 0, 900. They will only reset to what I want them to be by running xfce's Screensaver preferences dialogue manually.
man gdm3, info gdm3, grep -r DPMS in /etc/gdm3, grep -r dpms in /etc/gdm3 reveal nothing related to DPMS. I've done some searching and nothing useful.
there is an /etc/X11/app-defaults/XScreenSaver-nogl which has some DPMS settings but the times are too large (2 hours); the only thing that matches is the off setting which is specified there.
xscreensaver -no-splash is present in the output of ps so it is xscreensaver and not gnome-screensaver.
The weird thing is that I re-enabled my ~/.xinitrc in xfce's Session and Startup gui thing and it is being run, but the numbers are getting set wrong after it is run. (I put an echo command after xset dpms 900 1200 1500, and the file is appearing in ~)
Where does 600, 0, 900 come from? Mystified on how to proceed from here. I don't remember enough on how to see what's doing what. Is there some sys thing or proc thing I can monitor to find out what's setting these values?
Short version: my xset dpms values are getting reset to 600, 0, 900 every time I logout or reboot. They revert to 600, 0, 900 every time I get to my desktop. I use gdm3 and xfce. Where are these coming from?
I am having a problem with HTTPs in a double NAT'd network configuration. The scenario is like this..
[Code]...
Machines on these LANs can talk to each other no problem. There is also a NAT rule configured for traffic going from LAN A via LAN C out to the Internet. The Nokia is also doing NAT'ing. Normal web browsing works fine with this setup, but whenever I try to access HTTPS sites, it just hangs and eventually times out.Packet captures have showed lots of TCP Retransmission messages. If I logon directly to the Linux Router and fire up a browser, I am able to access HTTPS sites without any problems. This appears to be something to do with the traffic being NAT'd twice. Is there a way I can get around this without changing the config of the Nokia?
I'm sure I'm missing something pretty obvious, but I can't for the life of me stop my pysqlite scripts crashing out with a database is locked error. I have two scripts, one to load data into the database, and one to read data out, but both will frequently, and instantly, crash depending on what the other is doing with the database at any given time.I've got the timeout on both scripts set to 30 seconds: cx = sqlite.connect("database.sql", timeout=30.0)and think I can see some evidence of the timeouts in that i get what appears to be a timing stamp (e.g 0.12343827e10 1) dumped occasionally in the middle of my curses formatted output screen, but no delay that ever gets remotely near the 30 second timeout, but still one of the other keeps crashing again and again from this. I'm running RHEL5.4 on a 64 bit HS21 IBM blade, and have heard some mention about issues about multi-threading and am not sure if this might be relevant.
Packages in use are sqlite-3.3.6-5 and python-sqlite-1.1.7-1.2.1, and upgrading to newer versions outside of RedHat's official provisions is not a great option for me. Possible, but not desirable due to the environment in general.I have had autocommit=1 on previously on both scripts, but have since disabled on both, and am now cx.commit()ing on the inserting script and not committing on the select script. Ultimately as I only ever have one script actually making any modifications, I don't really see why this locking should ever ever happen
I've got this weird problem: when I reboot my Debian 8.3 server, I have to run through the crypto unlocking processes for my encrypted volumes a few times before I actually get to a login screen. The operation times out 85% of the time, leaving me to reboot and try over and over until the system is happy.

I had the same problem in previous builds where I chose Twofish instead of AES, and I was hoping that the timeouts would be fixed by switching to AES as my CPU has the AES instruction set. Obviously that didn't make a damn bit of difference.
What am I doing wrong, or what should I change in my setup? The encryption is a requirement. Could the problem be caused by something as stupid as using a RANDOM KEY instead of a PASSPHRASE on /tmp and swap?
explain the difference between these two commands. I'm currently reading about changing your mac address and both of these commands show up a lot. They sound like the same thing to me. Is one better than the other, or do you need to use both to change your mac address?
Code: sudo ifconfig eth0 down sudo /etc/init.d/networking stop
I have a problem when I want to use su I get this error:Code:su: pam_start: error 26I have googled it so I found this topic (http://www.linuxquestions.org/questi...r-26-a-615024/) but it didn't really help me. There was a reply on that topic and his question was what the output of this was:
A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.
I have read a lot of questions from people wanting to take Debian (or some other distribution) and make its sudo command act more like the way Ubuntu's sudo does. I want to do the exact opposite, I want to make Ubuntu's sudo command act more like the sudo command from another distribution. ie I want there to be one root password
Finally I managed to install my printer/scanner drivers.The last thing I need to do is to add the following two lines to 40-libsane.rules (which is a read only file):# Brother scanners ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes".How can I change permissions for this file or add these lines without changing permissions?
Problem: permissions for rsync and BackinTime. Setup: Ubuntu 11.04, Two internal HD, #1=main, single boot, #2=backup drive. Question: How do I set up my 2nd HD with correct permissions? Background: I had previously a dual boot XP+10.04 with a 2nd HD formatted as NTFS. With this I was able to use my rsync and backintime to my 2nd HD with no issue. My new set up is EXT4 on both HD.
(I even tried to reformat my 2nd HD as NTFS, but that didnt fix the issue) I followed [URL] to mount the 2nd HD and get permissions. But now when I run backintime i get this error: [E] Error: rsync: opendir "/home/myhome/.ssh" failed: Permission denied (13) I did my requisite reading for a newbie, and am stuck. I ran backintime as root, and it backed up ok. How do I run my user version of backintime? (i.e. How do I fix the permission issue?)
I have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:
chmod: changing permissions of `whatever': read-only filesystem.
This is my mount table:
[root@localhost ExtHDD]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) none on /proc type proc (rw) none on /sys type sysfs (rw)
