I am having issues connecting to a rstudio server I just installed. Can you please let me know if you know how to solve this? Thanks!
I just installed Rstudio server 0.99.485 64-bit on Ubuntu 13.10 (saucy) and am getting this error below:
The error in /var/log/syslog says:
ERROR Unexpected exception: locale::facet::Screateclocale name not valid;
LOGGED FROM: int main(int, char* const*) /home/ubuntu/rstudio/src/cpp/session/SessionMain.cpp:3166
The symptom is that the web UI says it's "unable to connect to service"
I have followed everything mentioned on this post, but it doesn't seem to work.
When I trace the rstudio-server process using sudo strace -f -e 'trace=!clockgettime,gettimeofday,futex,timerfdsettime,epollwait,epollctl' -p 10208 -o trace.txt, I am seeing this in the trace.txt ( below is what I used to log in:
10226 connect(10, {safamily=AFLOCAL, sunpath="/tmp/rstudio-rsession/"}, 28) = -1 ECONNREFUSED (Connection refused)
I've tried logged in using an invalid id to confirm that pam authentication is working fine
Also looked at this question and made sure there exists /home/<USERID> but still the problem is there.

Currently, we are trying to setup neutron for our cloud server. Since everyone is new to this, we are struggling a bit. When we entered this command:
openstack network create --share --external \
--provider-physical-network provider \
--provider-network-type flat provider
And it throws this error:
Error while executing command: HttpException: 503, The Keystone service is temporarily unavailable.: 503 Service Unavailable: The server is currently unavailable. Please try again at a later time.
We are following openstack docs guide to a T.
Does anyone know what causes this error and how to fix it?
Thanks.
I fixed it, it was a problem with MariaDB. When we updated it from 10.1 to 10.3, I couldn't access my DB, so when I fixed that error it works now.
I'm following this guide to use tpm2.0 simulator.
This is my situation:
Firstly, I ran:
$ ./tpm_server
TPM command server listening on port 2321
Platform server listening on port 2322
Then, I opened a new terminal and ran:
sudo tpm2-abrmd --allow-root --tcti=mssim
Nothing happened but in the previous terminal, there were:
$ ./tpm_server
TPM command server listening on port 2321
Platform server listening on port 2322
Command IPv6 client accepted
Platform IPv6 client accepted
I opened a new terminal more and ran command as the guide showed and there was some errors:
$ tpm2_pcrlist
ERROR:tcti:src/tss2-tcti/tcti-device.c:319:Tss2_Tcti_Device_Init() Failed to open device file /dev/tpm0: No such file or directory
ERROR: tcti init allocation routine failed for library: "device" options: "(null)"
ERROR: Could not load tcti, got: "device"
How should I do to fix it?
I got some error like you while running tpm2 command as you did.
You could try to run with "sudo". it works for me.
Same Issue!
Any answers. It was working but now it is not.
On a VPS with Fedora 23 I recently upgraded my rstudio-server. After this I could no longer login.
After many attempts to repair it I decided to start with a fresh VPS, unfortunately, even here the same problem appears. From systemctl I get:
ERROR system error 13 (Permission denied); OCCURRED AT:
rstudio::core::Error
rstudio::core::system::launchChildProcess(std::string, std::string,
rstudio::core::system::ProcessConfig,
rstudio::core::system::ProcessConfigFilter, PidType*)
/root/rstudio/src/cpp/core/system/PosixSystem.cpp:1297;
LOGGED FROM: rstu lines 1-13/13 (END)
Also:
id -u rstudio-server
gives
993
I have also set the minimum user id to 100.
Any thoughts would be much appreciated.
I have a new version of R installed on an aws-machine (which always come with an old version for some reason and it's near impossible to just have yum or apt-get to work). I want rstudio to point to this new version which I've built from source without throwing the old version away. I therefore go to /etc/rstudio/rserver.conf (documentation) and change the contents to:
# Server Configuration File
rsession-which-r=/root/R-3.2.1/bin/R
I can confirm that at this location a new version of R is installed but then I get an error after rstudio-server restarts.
root#ip-172-31-40-49 rstudio]$ rstudio-server restart
initctl: Unknown instance:
What am I to do?
Below worked for me:
1) check the process that used 8787
sudo fuser 8787/tcp
2) with the -k option to kill all process.
sudo fuser -k 8787/tcp
3) Start RStudio Server
sudo rstudio-server start
The solution above is provided here by Leon Zhang.
The first thing to do is to check your configuration with:
rstudio-server verify-installation
a number of times when updating R or RStudio I have run into the same error as you have and get the following error message.
-bash-4.1$ sudo rstudio-server verify-installation
29 Sep 2015 18:24:11 [rserver] ERROR system error 98 (Address already in use); OCCURRED AT: rstudio::core::Error rstudio::core::http::initTcpIpAcceptor(rstudio::core::http::SocketAcceptorService<boost::asio::ip::tcp>&, const std::string&, const std::string&) /root/rstudio/src/cpp/core/include/core/http/TcpIpSocketUtils.hpp:103; LOGGED FROM: int main(int, char* const*) /root/rstudio/src/cpp/server/ServerMain.cpp:436
rstudio-server start/running, process 48632
Although I have never been able to figure out the cause, I can suggest the following workaround:
1. change the port /etc/rstudio/rserver.conf for example from 8787 to 8788
2. open the new ports in your firewall settings. (allow access to the new port in /etc/sysconfig/iptables)
3. update your firewall: sudo /sbin/service iptables restart
4. restart Rstudio server: sudo rstudio-server restart
This has worked for me each of the ~4-5 times this has happened. Although I am not 100% sure this can help with your use case, it may. As an alternative, if you can use containers in your AWS setup, you may be interested in a great off-the shelf docker image with the latest R/Rstudio.
It happened for me on my Cento-7.x machine while I upgraded from old RStudio server to the new version. Rebooting the machine seems to have fixed the problem.
I've installed ArchLinux with VB on MacOS. I have network problems, I cannot resolve addresses. When trying pacman -S htop for example I get the following error :
:: Retrieving packages from extra...
error: failed retrieving file 'htop-1.0-1-x86_64.pkg.tar.xz' from mir1.archlinux.fr : Could not resolve host: mir1.archlinux.fr; Name or service not known
warning: failed to retrieve some files from extra
error: failed to commit transaction (download library error)
Errors occurred, no packages were upgraded.
If I ping mir1.archlinux.fr I get a response. I'm running Network in Nat Mode.
PS: If I run In Bridge Mode I have no problems.
Can someone help me fixing this problem?
Nevermind... disabling ipv6 fixed the problem.!
Check your /etc/resolve.conf or even change for opendns/google DNS.
Then check any domain like:
dig http://stackoverflow.com
finally:
pacman -Syu
