So I'm at a friend and hooked up my external EXT4 HDD to his router and it recognises it and he can connect his entire family to it and everything works fine. However, on my Ubuntu machine I can:  Go to my File Manager (Nemo) File Connect to Server   and that works fine! but I cannot: sudo mount -t smbfs //192.168.1.1/Fab-EXT4 /media/MichelNAS/ mount: unknown filesystem type 'smbfs'  sudo mount -t cifs //192.168.1.1/Fab-EXT4 /media/MichelNAS/ Password for root@//192.168.1.1/Fab-EXT4:   sudo mount -t cifs -o guest //192.168.1.1/Fab-EXT4 /media/MichelNAS/ mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)  sudo mount -t cifs //192.168.1.1/Fab-EXT4 -o user=,password= /media/MichelNAS/  mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)  sudo mount -t cifs -o rw,noperm,sec=none //192.168.1.1/Fab-EXT4 /media/MichelNAS/ mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)  However: smbclient --list=192.168.1.1 --no-pass  works perfectly and has as output: WARNING: The &quot;syslog&quot; option is deprecated Domain=[HOME] OS=[Unix] Server=[Samba 3.0.24]      Sharename       Type      Comment     ---------       ----      -------     IPC$            IPC       IPC Service (mymodem Sharing Files)     Fab-EXT4        Disk      Share Fab-EXT4 directory Domain=[HOME] OS=[Unix] Server=[Samba 3.0.24]      Server               Comment     ---------            -------     MYMODEM              mymodem Sharing Files      Workgroup            Master     ---------            -------     HOME                   So I'm obviously missing something completely stupid here, but I'm stumped as to why I cannot mount this share from the command line???
I have my CIFS setup in fstab and they are working as they are supposed to on boot. They mount as they should and work for a while. Out of nowhere it seems (could be after unlocking machine etc) I get "Host is down" error trying to access it. I have multiple and they are all down. They are also shared from the same server. At this time i check on a windows computer and an outdated 14.04 machine and they are up and functioning as they are supposed to. After clicking around on the shares in nautilus and getting repeat errors they will just start working again. To access a share that is "down" takes about 2-3min of randomly clicking different mounts and going back to the first one when automagically it shows the data in the mount point.  I do not have this problem on 14.04 machines that have not been updated in a while. All of those machines are fully functional and the CIFS never go "down". On 16.04 they were not a problem until more recently.  I have made sure to update every other day and have cleaned old linux headers (in hind sight i probably should have reverted). I do this because im begging for a fix to just appear but its been weeks of battling CIFS mounts without any solution.
Is there always an equilibrium point in space for gravity? find a $\int_{x}^{g(x)} f(t)\,dt = 1$ Let $f : [0, 2] → \mathbb{R}$ be a continuous, positive function and  $$\int_{0}^1 f(x)\,dx = \int_{1}^2 f(x)\,dx= 1$$ For each $x \in [0, 1]$, prove that there exists a unique function $g(x) \in [1, 2]$ such that $$\int_{x}^{g(x)} f(t)\,dt = 1$$ and $g \in C^1$. Well, I think in $g(x) = x +1$, but I'm not sure. Any hint is appreciated.  Thank you. Reading and searching long man pages How to print original variable's name in Python after it was returned from a function?

What is the rigor behind U subsitution? $ \int f(g(x)) dx = \int \frac {f(u)}{u'} du$  requires that  $ \int f(x) dx = \int f(x) \cdot dx$  but dx just represents the variable that F(x) +c is a function of. So why is it legal for dx to be treated algebriacally?  I tried investigating this property by using riemann summation:  $\lim\limits_{n \to \infty}(\sum_{k=1}^n f(\frac{kx}{n} )\frac{x}{n}) = \int_0^x f(t)dt= (F(x)+c)-(F(0)+c)$  and so you can define   $ \lim\limits_{n \to \infty} (\sum_{k=1}^n f(\frac{kx}{n} )\frac{x}{n})+F(0)+c)  = \int f(x) dx$  you can write $\frac{x}{n} = dx$ and $k\frac{x}{n}=kdx= x_k$  then you have  $ \lim\limits_{n \to \infty} (\sum_{k=1}^n f(x_k)dx)+F(0)+c) = \int f(x) dx$  since  dx is being written to be multiplied by the series, then you can define dx in different terms to aquire an integral in terms of other variables.   but that exists only in abstraction. I can't quite sufficiently complete the task of doing so. I've already tried clicking and holding the left button of my mouse, and it just won't work! Whenever I press it, it opens the game menu instead. Wild Magic Surge - What does "You cast ..." mean for your spell slots? In response to  question, I started to think about what it means when a Wild Magic Surge results in a "You cast spell-X".  So, "specific beats general" gives:   You can cast a second spell when you would not normally be allowed to You can cast a spell you don't know If the surge forces you to cast a concentration spell you would lose any concentration spell that you currently had active Subject to what the specific entry says you can target it how you like Unless the specific entry prohibits it you could use metamagic on the spell   I am pretty confident in all of the above but if anyone disagrees please address in an answer.  Here comes the question.  How does this impact on your available spell slots?  "You cast ..." to me suggests that if you have an applicable slot available then you have to use it to cast the spell because that is the general rule for casting spells but if you don't then "specific beats general" and it is cast anyway.  Specific examples:     You cast fireball as a 3rd-level spell centered on   yourself   This must be a 3rd level spell:   if you have a 3rd level slot available you have to use it? if you don't, if you have 5 sorcery points and a bonus action available must you use these to get that slot? if you don't have any of that then the spell goes off anyway?      You cast confusion centered on yourself.   No level specified and confusion is a 4th level spell:   if you have a 4th level slot available you have to use it? if you have a 4th, a 6th and an 8th level slot you can choose which one to use? if you have only a 5th level slot but also 6 sorcery points and a bonus action, you could choose to use the 5th level slot or use the points to create a 4th level slot? if you don't have any 4th level or higher slots but you have 6 sorcery points and a bonus action available must you use these to get that slot? if you don't have any of that then the spell goes off anyway?   And so on ... I found "A sledgehammer to crack a nut" as one example. What are some others?

Idiomatic phrase for small type words at end of a document Is there a phrase in English that that can be used in the following situation:  You read an article and from the title you understand that this is something positive, but if you read it all, very carefully, you will see that "small words" at the end reveal the reality.  The same situation is when signing contracts, when something negative for the customer is indicated in the end with small letters Let $\mathbb F$ be a field and $\mathbb  K $ be an extension field of $\mathbb F$  such that $\mathbb K$ is algebraically closed.   Let $\mathbb L$ be the field of all elements of $\mathbb K$ which are algebraic over $\mathbb F$. Then $\mathbb L_{|\mathbb F}$ is an algebraic extension.   My question is : Is $\mathbb L$ algebraically closed ?  I am trying to prove the existence of algebraic closure, so please don't assume that every field has an algebraic closure.
