  • stunnel not working - stunnel.pem: No such file or directory

    - by Marronsuisse
    I am trying to install stunnel on an amazon LINUX machine. (i want to configure postfix so that it sends its emails through amazon ses) I first tried to install from the tar.gz package download from http://www.stunnel.org and installed with the commands: ./configure make make install but than the stunnel command was still not found. Then I installed with yum install stunnel. But now when I try I get: sudo stunnel 2012.06.23 06:51:53 LOG7[20071:3078289200]: Snagged 64 random bytes from /root/.rnd 2012.06.23 06:51:53 LOG7[20071:3078289200]: Wrote 1024 new random bytes to /root/.rnd 2012.06.23 06:51:53 LOG7[20071:3078289200]: RAND_status claims sufficient entropy for the PRNG 2012.06.23 06:51:53 LOG7[20071:3078289200]: PRNG seeded successfully 2012.06.23 06:51:53 LOG3[20071:3078289200]: stunnel.pem: No such file or directory (2) So it seems there is still a problem with the install. When I use the locate stunnel command, I see files a bit everywhere. How can I do to have a clean install of stunnel? Edit: i was following this procedure: http://docs.amazonwebservices.com/ses/latest/DeveloperGuide/SMTP.MTAs.SecureTunnel.html when I got stuck at point 5 and got the stunnel.pem: No such file or directory message.

  • MediaWiki Math Extension Out of Sync

    - by kfmfe04
    I am trying to run MediaWiki 1.19.2 on Ubuntu Linux (3.0.0-26-generic #42-Ubuntu AMD 64). It installs fine via tar.gz, however, I run into problems when trying to install the Math extension (via git clone from its repository). I get the following error in the Apache logs: PHP Fatal error: Call to undefined method FSFileBackend::getRootStoragePath() in /var/www/abc.com/html/mediawiki-1.19.2/extensions/Math/Math.body.php on line 361, referer: http://intra.abc.com/wiki/index.php?title=Quality&action=submit so apparently, the latest Math extension is out-of-sync with MediaWiki 1.19.2; the latest Math extension is apparently using post-1.19.2 methods. I tried looking through the git logs for some indication (a tag, perhaps?) of which revision of Math worked with 1.19.2, but no luck. Anyone have any suggestions? Thanks in advance. Edit: Just my luck - after posting this message, I found this link. I think this version should do the job. Consider this question closed/answered.

  • Ubuntu Postfix Gmail SMTP Relay Not Working

    - by Nick DeMayo
    I currently have postfix set up to relay messages from my websites through gmail, and up until recently it was working perfectly.

  • How do I install PHP 5.3 on CentOS?

    - by fivelitresofsoda
    I have to install PHP 5.3 on my CentOS server. If I do yum install php, the base repository installs 5.1.6 which is too old for the applications I need to install. So I've been trying to use the IUS repository, following the official instructions from IUS: root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-2.ius.el5.noarch.rpm root@linuxbox ~]# wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm root@linuxbox ~]# rpm -Uvh ius-release*.rpm epel-release*.rpm OK. Now I simply do yum install php53, etc. for all I need... but I get this error: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Check Error: file /usr/bin/php from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /usr/bin/php-cgi from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /usr/share/man/man1/php.1.gz from install of php53u-cli-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-cli-5.1.6-27.el5_5.3.x86_64 file /etc/php.ini from install of php53u-common-5.3.4-3.ius.el5.x86_64 conflicts with file from package php-common-5.1.6-27.el5_5.3.x86_64 Error Summary ------------- I have no idea on how to solve this. I think I have to delete the base packages. However, as someone new to Linux, I don't know how to do that.

  • Mac Port error installing gsoap

  • Generic RPM package for Python 2.x

    - by RaphDG
    I have a python application, it can run on Python = 2.6 and it's architecture independant. I need the rpm package of this application to be installed on Fedora 14 (python 2.7) and Centos 6.2 (python 2.6). I currently use mock to build one rpm package for each "flavour" and it works well. I apparently can't install the Centos compiled rpm on Fedora. It gives me this error message : error: Failed dependencies: python(abi) = 2.6 is needed by myapp-0.9.el6.noarch Here is the relevant part of my .spec file : %{!?python_sitelib: %global python_sitelib %(%{__python} -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())")} %{!?python_sitearch: %global python_sitearch %(%{__python} -c "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))")} Name: myapp Version: #VERSION# Release: #RELEASE#%{dist} Summary: myapp Group: Development/Languages License: Apache v2 Source0: %{name}-%{version}-#RELEASE#.tar.gz BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) BuildArch: noarch BuildRequires: python-devel BuildRequires: python-setuptools %description myapp %prep %setup -c %build %{__python} setup.py build %install %{__rm} -rf %{buildroot} %{__python} setup.py install -O1 --skip-build --root %{buildroot} Do I really have to use mock and build 2 rpms or is there another way to create a single generic 2.x rpm package ?

  • What can I do to lower bandwidth cost on a bandwidth heavy site?

    - by acidzombie24
    The easiest answer is CDN but I'd like to ask. A friend of mine has a server that is used for mirror downloads. He says he is doing about 10TB of bandwidth a month which shocked me (I wonder if he is lying). I seen his site and he has no ads. I suspect he might close his website once he gets the bill. Anyways I was wondering since his CPU/RAM is not being used and his HD usage is around 15gb what he can do to lower cost if he continues this site. I said put up ads but I don't know if ads would cover it I found one CDN which offers $0.070 / GB. 10240gb (10TB) * .07 = $717 a month. That seems a little steep but he is using lots of traffic due to it being a mirror site. Also using a CDN doesnt make sense as he doesn't need multiple servers hosting the files in different areas (which is one reason he isn't using that now). He just needs a big upload pipe Is there something he can do? At the moment he is paying $200 a month on a dedicated server and he is using WAY more bandwidth then he should be using. Side question: Can gz-ing files large already compressed files help? like on (zip, rars, etc)

  • Hostname error on my Slicehost Ubuntu server

    - by allesklar
    Like many folks who upgraded to Rails 2.2, I got an exception raised when sending an email. This version of Rails or later does require using tls for sending emails. The message in the production log file says: hostname was not match with the server certificate I did a whole lot of research and work on this and did everything I could. I changed my slice's hostname to ohlalaweb.com. If I run the command 'hostname' at the CL I get: ohlalaweb.com Postfix seems to work fine. I can send emails from the CL to my gmail, yahoo, and google apps gmail accounts with no problems. Here is the result of cat /etc/postfix/main.cf # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

  • Moving domain and keeping IMAP email - Linux Evolution, Mac Mail

    - by Douglas Squirrel
    This question is about keeping email during a server move, where the clients are Linux (me) and Mac (my wife) using IMAP. I receive email at [email protected] using a webmail service that my hosting company (1and1) provides. I read it via IMAP in evolution, so I should have copies of all the emails on my local machine. I have just moved mydomain.com from one type of account to another, and the hosting company don't move my existing email on the server when I do this - I assume they move my account to a different mailserver, and don't choose to provide a migration path for the email to move too (yes, this is annoying). Before migrating, I backed up Evolution (File - Backup settings) and did a spot-check in the evolution-backup.tar.gz file to be sure that my mail was in there. After migrating, I restored (File - Restore settings) and had hoped that I would see all my mail again. Unfortunately, Evolution just shows me new mail sent to the account, not the old mail. Is there a way to get the old mail back in the mailserver, or at least displaying in Evolution, as it was before the move? If not, can I read it in some convenient way, e.g. in Evolution offline or in a text file (then I can pick the mails I really want to keep and resend them to myself)? Also, I am about to do a similar move for my wife's domain, [email protected]. She reads her mail on a Mac using IMAP to Apple Mail. Is there anything I can do to make the move smooth for her? (I have backed up [her user]/Library/Mail already, but not sure what to do once the move is done.)

  • Linux: Managing users, groups and applications

    - by RN
    I am fairly new to linux admin so this may sound quite a noob question. I have a VPS account with a root access I need to install Tomcat, Java on it and later other open source applications as well. Installation for all of these is as simple as unzipping the .gz in a folder. My questions are A) Where should I keep all these programs? In Windows, I typically have a folder called programs under c:\ where I unzip all applications. I plan to have something similar here as well. Currently, I have all these under apps folder under/root- which I am guessing is a bad idea B) To what group should Tom belong to ? I would need a user - say Tom who can simply execute these programs. Do I need to create a new group? or just add Tom to some existing group ? C) Finally- Am I doing something really stupid by installing all these application by simply unzipping them? I mean an alternate way would be to use Yup or RPM or something like that to install these applications. Given my familiarity and (tight budget) that seems too much to me. I feel uncomfortable running commands which i don't understand too well

  • How to configure fastcgi to work with ligttpd in ubuntu

    I am able to run lighttpd on ubuntu 9.10. But when i tried to setup fastcgi with lighttpd by putting this in the ligttpd.conf file: #### fastcgi module fastcgi.server = ( "/fastcgi_scripts/" => (( "host" => "127.0.0.1", "port" => "9098", "check-local" => "disable", "bin-path" => "/usr/local/bin/cgi-fcgi", "docroot" => "/" # remote server may use # it's own docroot )) ) This is what I get in the error.log in ligttpd: 2010-03-07 21:00:11: (log.c.166) server started 2010-03-07 21:00:11: (mod_fastcgi.c.1104) the fastcgi-backend /usr/local/bin/cgi-fcgi failed to start: 2010-03-07 21:00:11: (mod_fastcgi.c.1108) child exited with status 1 /usr/local/bin/cgi-fcgi 2010-03-07 21:00:11: (mod_fastcgi.c.1111) If you're trying to run your app as a FastCGI backend, make sure you're using the FastCGI-enabled version.

  • Rsyslog stops sending data to remote server after log rotation

    - by Vincent B.
    In my configuration, I have rsyslog who is in charge of following changes of /home/user/my_app/shared/log/unicorn.stderr.log using imfile. The content is sent to another remote logging server using TCP. When the log file rotates, rsyslog stops sending data to the remote server. I tried reloading rsyslog, sending a HUP signal and restarting it altogether, but nothing worked. The only ways I could find that actually worked were dirty: stop the service, delete the rsyslog stat files and start rsyslog again. All that in a postrotate hook in my logrotate file. kill -9 rsyslog and start it over. Is there a proper way for me to do this without touching rsyslog internals? Rsyslog file $ModLoad immark $ModLoad imudp $ModLoad imtcp $ModLoad imuxsock $ModLoad imklog $ModLoad imfile $template WithoutTimeFormat,"[environment] [%syslogtag%] -- %msg%" $WorkDirectory /var/spool/rsyslog $InputFileName /home/user/my_app/shared/log/unicorn.stderr.log $InputFileTag unicorn-stderr $InputFileStateFile stat-unicorn-stderr $InputFileSeverity info $InputFileFacility local8 $InputFilePollInterval 1 $InputFilePersistStateInterval 1 $InputRunFileMonitor # Forward to remote server if $syslogtag contains 'apache-' then @@my_server:5000;WithoutTimeFormat :syslogtag, contains, "apache-" ~ *.* @@my_server:5000;SyslFormat Logrotate file /home/user/shared/log/*.log { daily missingok dateext rotate 30 compress notifempty extension gz copytruncate create 640 user user sharedscripts post-rotate (stop rsyslog && rm /var/spool/rsyslog/stat-* && start rsyslog 2&1) || true endscript } FYI, the file is readable for the rsyslog user, my server is reachable and other log files which do not rotate on the same cycle continue to be tracked properly. I'm running Ubuntu 12.04.

  • Problems using Mesa demos

    - by Rodnower
    Hello, I successfully installed Mesa with "yum install Mesa*" and downloaded MesaDemos-7.8.tar.gz archive. Now I try follow instructions from "Mesa3d.org - Download / Insall - Compiling and Installing - 1.5 Running the demos", but in progs/demos there is only *.c files, when I try to compile them, I get many similar errors like: gears.c:(.text+0x54): undefined reference to `glShadeModel' I guess that this is very noob question, and I understand that there is very simple solution, but I haven't any idea... In beggining of the file there are all necessary #includes: #include <math.h> #include <stdlib.h> #include <stdio.h> #include <string.h> #include <GL/glut.h> So I have some questions: Is there some Mesa forum on the web? Is there some compiled demos? Is there some site with well described examples of Mesa using? What I need for compile those examples? I have CentOS 5 Thank you for ahead.

  • Error in Bind9 named.conf file. Bind won't start.

    - by tj111
    I'm trying to setup a DNS server on an Ubuntu Server machine (10.04). I configured an entry in named.conf.local to test it, but when trying to restart bind9 I get the following error: * Starting domain name service... bind9 [fail] So I checked the output of syslog and this is what I get.

I went through it and deleted a blank line just for the hell of it, but I can't see how it figures there's an error in there. Note that before this I did have an error in named.conf.local, but it showed up properly in syslog and I fixed it, so it is reporting the correct file. Here is the contents of named.conf: // This is the primary configuration file for the BIND DNS server named. // // Please read /usr/share/doc/bind9/README.Debian.gz for information on the // structure of BIND configuration files in Debian, *BEFORE* you customize // this configuration file. // // If you are just adding zones, please do that in /etc/bind/named.conf.local include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones";

  • Recover mysql database - mysqldump gives "table <tablename> doesn't exist (1146)"

    - by Matthew
    Backstory Ubuntu died (wouldn't boot) and I couldn't fix it. I booted a live cd to recover the important stuff and saved it to my NAS. One of the things I backed up was /var/lib/mysql. Reinstalled with Linux Mint because I was on Ubuntu 10.0.4 this was a good opportunity to try a new distro (and I don't like Unity). Now I want to recover my old mediawiki, so I shut down mysql daemon, cp -R /media/NAS/Backup/mysql/mediawiki@002d1_19_1 /var/lib/mysql/, set file ownership and permissions correctly, and start mysql back up. Problem Now I'm trying to export the database so I can restore the database, but when I execute the mysqldump I get an error: $ mysqldump -u mediawikiuser -p mediawiki-1_19_1 -c | gzip -9 > wiki.2012-11-15.sql.gz Enter password: mysqldump: Got error: 1146: Table 'mediawiki-1_19_1.archive' doesn't exist when using LOCK TABLES Things I've tried I tried using --skip-lock-tables but I get this: Error: Couldn't read status information for table archive () mysqldump: Couldn't execute 'show create table `archive`': Table 'mediawiki-1_19_1.archive' doesn't exist (1146) I tried logging in to mysql and I can list the tables that should be there, but trying to describe or select from them errors out the same way as the dump: mysql> show tables; +----------------------------+ | Tables_in_mediawiki-1_19_1 | +----------------------------+ | archive | | category | | categorylinks | ... | user_properties | | valid_tag | | watchlist | +----------------------------+ 49 rows in set (0.00 sec) mysql> describe archive; ERROR 1146 (42S02): Table 'mediawiki-1_19_1.archive' doesn't exist I believe mediawiki was installed using innodb and binary data. Am I screwed or is there a way to recover this?

  • Installing Tomcat on CentOS 5

    - by andybaird
    Disclaimer: I am not a server admin, I am a windows user that has lead a life of sinful installation wizards and drag and drop I'm attempting to install Tomcat on CentOS 5 hosted by a MediaTemple dedicated virtual server. I basically followed this guide: Installed jpackage and configured the yum.repo.d jpackage file to set enabled=1 Used yum to install java (yum install java) Downloaded the binary distribution of tomcat with "wget http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.14/bin/apache-tomcat-6.0.14.tar.gz" set JAVA_HOME to point at the jdk location I found with "export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/" I gunzip/untar the Tomcat files and run ./startup.sh to start the Tomcat server. That is supposed to put the Tomcat server at myserver.com:8080 - however, I just get a could not contact host error when I try to browse to it (or when I try 'curl localhost:8080' from SSH) After I type ./startup.sh, here is the console output: [root@myserver bin]# ./startup.sh Using CATALINA_BASE: /root/apache-tomcat-6.0.14 Using CATALINA_HOME: /root/apache-tomcat-6.0.14 Using CATALINA_TMPDIR: /root/apache-tomcat-6.0.14/temp Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/ [root@myserver bin]# Is there a step I have missed here? Edit: I've now discovered by looking at the log the following error is occuring: Error occurred during initialization of VM Could not reserve enough space for object heap

  • repair partition table

    - by m.sr
    Hallo. I've just overwritten my partition table of my system's hard disk. i made a cfdisk on the wrong device (/dev/sda instead of /dev/sdd), deleted all partitions, made one new primary spanning over the whole device, set its type to 07 (NTFS) and hit write. So here i am with my system running. Until i reboot, i hope/guess nothing will change - meaning: all my data is accessible (I'm currently making a dd-backup of the whole device and plan to make a .tar.gz-backup of the most important data later). I also backed up /proc/partitions, /proc/diskstats (even though i guess this is more about throughput and stuff like this ...) and /sys/block/sda/sda?/{start,size}. Some further things i know: 4 primary partitions 1st partition: ~100Mb, ext3, /boot 2nd partition: ~100Mb, "Win7 Boot Partition", ntfs(?) 3rd partition: ~20...30GB, Win7, ntfs 4th partition: ~20...30GB, luks-encrypted device The luks- de crypted device is a LVM-PV The /, /home & swap-partitions are all LVs on the (VG on the) above noted PV So my questions: What is the simplest way to just write the kernels partition table to the disk? What is the simplest way to take the above mentioned (and perhaps other I don't know of ...) data and generate the partition table? Are there any problems to take care of regarding to luks and/or lvm? Is there any data I should backup before rebooting (meanig stuff from kernel [ /sys/..., /proc/...] and so on, which could help me regenerate the partition table)? Thanks a lot! P.S.: debian sid, Kernel 2.6.34-1-amd64 from debian-experimental, 80GB Intel SSD

  • How to start using twill?

    - by brilliant
    How do I start using twill? I have just downloaded it, unpacked it and clicked on the setup .py file in the folder. The black window (terminal) appeared for a moment and vanished. (I do have Python 2.5 installed on my computer - along with SDK from Google App Engine) In the twill documentation section it says: Downloading twill The latest release of twill is twill 0.9, released Thursday, December 27th, 2007; it is available for download at http://darcs.idyll.org/~t/projects/twill-0.9.tar.gz. You can also use Python's easy_install to install or upgrade twill. twill works with Python 2.3 or later. To start using twill, install it and then type twill-sh. At the prompt type: go http://www.slashdot.org/ show showforms showhistory I am not clear from this passage what I am supposed to type (only "twill-sh" or "twill-sh" and all the words under that line) and where (I tried typing it in the command prompt window of my computer - to no avail) Can, anyone, please, help me out here? Thank You in advance.

  • How do I install the latest version of packages in Ubuntu?

    - by Roman
    For example I want to install the latest version of "numpy". I type the following: "sudo apt-get install python-numpy". When I type this the first time it installs something and if I type this the second time it writes that I have already the latest version of numpy. However, I see that my version of numpy is 1.1.1. and I know that it NOT the latest version. Why it happens and how this problem can be solved? I can find the *tar.gz file with the latest version, I can extract files with the archive and than I need to rune one of the scripts which will be somewhere among the extracted files. But I do not like this way. It is too complicated. I do not know where I should put all these files, I do not know which dependencies I should install before I run the script for the installation of numpy, I do not know where numpy will be put after installation and so on. Is there an easy way to get the latest version of numpy?

  • Apple Mac OS X Mavericks inside Virtual Box

    - by John Sonderson
    I have a few questions regarding Mac OS X and OS virtualization. A. Given all the legal restrictions imposed by Apple on Apple products, I would like to know whether it is legal to install the new and freely downloadable Apple Mac OS X Mavericks inside Oracle Virtual Box. B. What about older OS X versions such as Mountain Lion? C. How many machines can I install it on. What if I don't use the Mac to which the OS is downloaded but only use it on Virtual Box, and prefer to, say, install Linux on the Mac computer so that it doesn't become unusable due to the single user license policy and me running the OS on Windows 7 within Virtual Box? D. I have a PC running Windows 7 but would like to get the OS off a second had Mac I'm planning to purchase for this purpose. How must we proceed to copy the OS to an ISO so that I can install it on Windows 7? I am unfamiliar with Macs and do not know what software to use for the purpose, nor where the OS is downloaded to (as an ISO, .app executable, .gz or .zip file or whatever). If anyone could provide some guidance with the process I would sincerely appreciate it. Thanks.

  • Trying to setup catchall mail forwarding on my rackspace's cloudspace server

    - by bob_cobb
    I'm running Ubuntu 12 Precise Pangolin and am trying to configure my server to catchall mail sent to it and forward it to my gmail address. I've been trying lots of examples online like editing my main.cf file which looks like this: smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = destiny alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = destiny, localhost.localdomain, localhost relayhost = smtp.sendgrid.net mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 51200000 recipient_delimiter = + inet_interfaces = all inet_protocols = all In my /etc/postfix/virtual I have: @mydomain.com [email protected] @myotherdomain.com [email protected] Which isn't working when I email [email protected] or [email protected]. So I got the recommendation to add the following to my /etc/alias: postmaster:root root:[email protected] restarted postfix, and tried emailing [email protected] or [email protected] but it still won't send. Does anyone have any idea what I'm doing wrong here? I'd appreciate any help.

  • Wastage of resources in Virtualization

    - by Sabeen Malik
    I have asked this question on SO, but was suggested that i ask it here on SF, so here it goes. http://stackoverflow.com/questions/3010753/wastage-of-resources-in-virtualization I am not sure if this is the right place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the memory and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20? Further Notes: Here is an example of what i am thinking: I have a master-slave configuration for a long running, cpu + memory intensive process, which can be distributed to 4 machines. Lets say when the process runs on these 4 machines with lets say 1 Gh CPU and 1 Gig RAM, i get 400 results per hour from the cluster (assuming 100 results from one machine) . Now i get a bigger machine ( lets say 4Gh and 4 Gig RAM), have 4 virtual hosts on it with 1 Gz CPU and 1 Gig RAM. Will this configuration give me the same 4 results per hour from these 4 virtual hosts?
