| Can SSH but cannot connect via HTTP Posted: 05 Apr 2022 01:20 AM PDT I am trying to set up a web application on my server. I can ssh to the server but when I connect via any browser (using IP or URL) I get no response. Running sudo netstat -tulpn | grep LISTEN gives the following result tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 31747/docker-proxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 30899/docker-proxy tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN 1441/systemd-resolv tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 27775/sshd tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 9949/postgres tcp 0 0 127.0.0.1:35757 0.0.0.0:* LISTEN 1481/containerd tcp6 0 0 :::8080 :::* LISTEN 31754/docker-proxy tcp6 0 0 :::80 :::* LISTEN 30906/docker-proxy tcp6 0 0 :::22 :::* LISTEN 27775/sshd tcp6 0 0 ::1:5432 :::* LISTEN 9949/postgres
Which looks fine to me although I do not have a lot of experience with netstat. The react application runs on port 80, the server on port 8080, both in a docker. When I ssh to the server and try curl localhost:80 or curl localhost:8080 respectively the proper pages are returned. Only when I connect from the outside, I cannot reach my services. What are the best ways to debug this? |
| DDOS AWS API Gateway protection Posted: 05 Apr 2022 01:11 AM PDT I want to secure API Gateway (HTTP) with Cloudfront + WAF. After reading docs I think that API Gateway endpoint is still exposed to the Internet. The only thing that protects API Gateway is verification of Header in WAF. Attacker can still find API Gateway in the Internet and perform DDOS attack directly to API Gateway endpoint without going through Cloudfront. Is this approach considered as secure? Cloudflare is using Tunnel to make sure that your infrastructure is not exposed to the Internet. I think this approach is much more secure. Is something like this available in AWS? |

| Fedora 34: How do I stop the console going blank and reduce the screen resolution on a text only console? Posted: 05 Apr 2022 12:45 AM PDT I have a Fedora 34 server edition connected to a TV. There is no GUI installed and I only have a text based console. My problem is that the console will blank after some time (I think a screen saver is kicking in) and also the font size is too small to read. I would like to disable the screensaver and reduce the screen resolution because the text is too small to read. Any help would be appreciated. |

| NTP Debian: how do I know, if the last poll was successfull Posted: 05 Apr 2022 01:04 AM PDT I've got the task to write an application, that supports NTP communication. Everything works fine so far, but I need to know, if the last ntp poll was successful or not. When I pull out the network cable, ntpstat even tells me even in the next morning, that everything was fine. But there was no NTP communication the whole night... Have you got any ideas? Thank you! Pinging is not a good solution, bc response could be turned off by the server or the server is reachable, but the ntp daemon is not running. |

| Alert when Admin logs into Azure Posted: 04 Apr 2022 09:06 PM PDT I setup an Office365/Azure tenancy for a small charity I help. I am keen to setup automated reporting that sends an email when someone logs in as an admin account (i.e with a particular role or group). The main things I am trying to achieve are - Visibility of when a 3rd party support organisation logging in to change the tenancy
- Visibility of when an internal staff member logs in, including staff who have moved on and we believe their accounts are disabled
- Visibility of unknown accounts logging in (i.e. a newly created admin account by a nefarious actor)
All I have been able to find is how to alert on a specific user, which can help with the first 2 requirements (although it means setting up an alert per account), however it doesn't cover the 3rd requirement. Is it possible to setup an alert in Azure to send an email to a nominated address when any account with the Global Admin role logs in ? |
| Using a compressed initrd when pxe booting Posted: 04 Apr 2022 09:01 PM PDT I'm using netboot/pxeboot with grub. menuentry "Install Ubuntu 20.04" { set gfxpayload=keep echo 'Loading vmlinuz ...' linux /tftp/vmlinuz ip=dhcp netboot=nfs nfsroot=10.0.0.20:/data/netboot/nfs/ubuntu2004/ boot=casper toram noquiet splash=off console=tty0 console=ttyS1,57600n8 --- echo 'Loading initrd, this takes a long time ...' initrd /tftp/initrd }
It works fine, however, the loading of initrd over tftp is taking a long time (30+ minutes). I would like to compress (gz/bz2) this file to save on some file transfer time. I had seen some examples out there referring to a initrd.gz (One example: https://unix.stackexchange.com/questions/217002/which-iso-file-vmlinuz-and-initrd-gz-to-use-for-installing-centos-from-multiboo) but when I tried to just compress the file with gzip and use it, I get an error such as: [ 12.543547] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6 [ 12.558487] Please append a correct "root=" boot option; here are the available partitions: [ 12.575161] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Is there a way to compress this file so it can transfer a smaller file size, and have it uncompress before it tries to mount the root fs? Alternatively, is there a way to transfer it over a different protocol (HTTP/FTP/SFTP/SCP/etc) ? |
| Is the network interface card(NIC) prerequisite of IP addresses? [closed] Posted: 05 Apr 2022 01:07 AM PDT Here is the command to assign IP address to an interface for Linux server. ip addr add ADDRESS dev IFNAME
Where IFNAME is the interface name and ADDRESS is the IP address you want to assign to the interface. To add address 192.168.121.45 with netmask 24 to device eth0, you would type: sudo ip address add 192.168.121.45/24 dev eth0
NIC belongs to the physical layer, IP belongs to the IP layer, they are independent. I would like to ask further questions to figure out the relation between NIC and IP address. - Is the NIC prerequisite of IP address?
- Must IP address be attached to a NIC?
- Can ip address live alone on IP layer without NIC?
Reference - Linux ip Command: Assign IP addresses to an interface
- serverFault: Can a single network card have 2 IP addresses?

| 802.1q multicast blocked by Cisco router Posted: 05 Apr 2022 01:20 AM PDT We are using Cisco Catalyst 1000 switch (C100-16P-2G-L to be precise) and having a trouble of passing tagged multicast from one its port to another. We would like to pass it as it is (tagged), I assume it should be possible but how to configure (we need to pass multicast traffic with vlan id=257)? default configuration definitely doesn't work. Some additional details related to default configuration: - tagged (id=257) multicast is not passing through!
- untagged multicast is passing through
- tagged unicast is passing through
This type of switch has vlan=1 as default, so if I send multicast traffic tagged with vlan id=1, it goes out de-tagged - this is not what I need. Also I found that: Switch#show topology Topology Address Family Associated VRF State base ipv4 default UP base ipv6 default DOWN base ipv4 multicast default DOWN base ipv6 multicast default DOWN
could it be related, and how to change the topology? These packets are sent from host: $ sudo mz v_eno1 -v -c 0 -d 1s -B 239.0.0.5 -t udp "dp=32000" -P "AAAA" IP: ver=4, len=32, tos=0, id=0, frag=0, ttl=255, proto=17, sum=0, SA=198.19.4.250, DA=239.0.0.5, payload=[see next layer] UDP: sp=0, dp=32000, len=12, sum=0, payload=41:41:41:41 ....

We have a very similar setup on another environment, and it worked fine. But on this setup, it happens that we get access denied around 50% of the times we try to mount a share: # failed attempt bash-4.4$ sudo mount -t nfs -o sec=krb5 server.com:/homes/francis test -vvvv mount.nfs: timeout set for Sat Apr 2 16:28:32 2022 mount.nfs: trying text-based options 'sec=krb5,vers=4.2,addr=192.168.1.89,clientaddr=192.168.2.29' mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'sec=krb5,vers=4,minorversion=1,addr=192.168.1.89,clientaddr=192.168.2.29' mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'sec=krb5,vers=4,addr=192.168.1.89,clientaddr=192.168.2.29' mount.nfs: mount(2): Permission denied mount.nfs: trying text-based options 'sec=krb5,vers=4,addr=192.168.1.88,clientaddr=192.168.2.29' mount.nfs: mount(2): Permission denied mount.nfs: trying text-based options 'sec=krb5,addr=192.168.1.89' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.1.89 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.1.89 prog 100005 vers 3 prot UDP port 32767 mount.nfs: mount(2): Permission denied mount.nfs: trying text-based options 'sec=krb5,addr=192.168.1.88' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.1.88 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.1.88 prog 100005 vers 3 prot UDP port 32767 mount.nfs: mount(2): Permission denied mount.nfs: access denied by server while mounting hypatia.uio.no:/uioit-usit-drift-homes/francis # working attempt two seconds later bash-4.4$ sudo mount -t nfs -o sec=krb5 server.com:/homes/francis test -vvvv mount.nfs: timeout set for Sat Apr 2 16:30:09 2022 mount.nfs: trying text-based options 'sec=krb5,vers=4.2,addr=192.168.1.88,clientaddr=192.168.2.29' mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'sec=krb5,vers=4,minorversion=1,addr=192.168.1.88,clientaddr=192.168.2.29' mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'sec=krb5,vers=4,addr=192.168.1.88,clientaddr=192.168.2.29' mount.nfs: mount(2): Permission denied mount.nfs: trying text-based options 'sec=krb5,vers=4,addr=192.168.1.89,clientaddr=192.168.2.29'
I have checked the logs on the client side, and not much there that points to the cause of the failure to mount. It works one time, and it won't work two seconds later. Or vice-versa. I thought at first it could be a cross-mount issue, but I also tried with the upper directory of the share, and it was the same problem. Any hints on what can be the problem? |

At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: ius/x86_64

| AWS Freeable memory decreases from 16GB to 1GB Posted: 04 Apr 2022 11:03 PM PDT I have a MYSQL database hosted on RDS with 16GB RAM. I'm using an r4.large with 20GB General purpose SSD storage. We are using a microservice architecture and has 6 backend containers. So the request will hit the RDS from that 6 backend servers. The operation on our application has more read and write operations. We are trying a load test of our application and using 10 to 20 users for the load test. But while testing and when we reached nearly 20 users for load test, we noted that the response time is really high. While checking on RDS metrics, we figured out that the freeable memory came down from 15GB to nearly 1GB and not coming up also. The main issue we faced was when we again test the load using 10 users, the response time taken was really high. It was not comparable with the initial test results of 10 users. I'm not sure it is the freeable memory causing the issue, or else any other factor. How can I figure out the issue and resolve it? Any help would be appreciated. |
| Where do I put group_vars in an ansible setup and galaxy role Posted: 04 Apr 2022 09:04 PM PDT I'm trying to use my first playbook with a galaxy role and while I can get the role to run, I can't seem to get it to find the group_vars I've defined. The role is nickjj.mariadb (not that that probably matters) but in the docs its stated that group_vars should be relative to your inventory directory. I've tried a couple of different things but so far no dice. tree . ├── group.vars │ └── siteservers.yml ├── install_maria.yml ├── inventory │ └── hosts └── update-apt.yml
is what I have for the layout and I'm running the playbook with ansible-playbook -i inventory/hosts -l siteservers install_maria.yml -K
It is finding the ip address of the server from the hosts file happily, but doesn't seem to pick up the variables from siteservers.yml. Where should this be put? Am I close with the layout or is it all wrong? |
| Apache mod_wsgi tuning Posted: 04 Apr 2022 09:04 PM PDT I have a django site on webfaction that uses apache + mod_wsgi. Site is getting around 1000 requests per minute. But it makes some calculations, so request takes about 5-10 seconds. I use the following configuration StartServers 2 MinSpareThreads 10 MaxSpareThreads 25 ThreadLimit 25 ThreadsPerChild 25 MaxClients 75 MaxRequestsPerChild 1000
threads=15 processes=12
The problem is high CPU usage and it takes time to process a simple static page without calculations (looks like Apache queued the request). So what I want is for Apache to quickly accept requests. I'm totally lost because of number of parameters, I also don't quite understand what they mean. What do we need StartServers and MaxRequestWorkers for? Any help and/or explanations will be highly appreciated. I have 8GB of RAM. Apache MPM Worker. mod_wsgi 4.4.21. Thank you in advance. |
| CentOS 7 sssd with AD - getent passwd slow in response Posted: 05 Apr 2022 01:04 AM PDT CentOS 7 + SSSD + AD AD user is created through bash script. To confirm the AD user account is created I am using getent passwd <username>. It is not returning the user account created in AD immediately, but it is returning the user account after a minute or so when using the same getent passwd <username>. Is there any config parameter to change in sssd.conf? |
| Unable to restart a systemctl service remotely as a non root user Posted: 04 Apr 2022 10:01 PM PDT I have a systemd.socket named gunicorn.socket which I would like to restart after updating some code on a remote server. I've followed the steps detailed in Allowing a non-root user to restart a service and systemctl keeps asking for my user password.

| Outlook 2010 Exchange Account - Folders only sync when clicked Posted: 05 Apr 2022 12:02 AM PDT I work at a university and we have recently switched our email from an old system managed by the university to Office 365. Because the old system only allowed a very small amount of server space, I used a POP setup and kept all of my email locally. Now that I have tons of space I want to move it back to the cloud. I set up an Exchange account in Office using the new Office 365 settings. All of my old mail and folders are now setup to be synchronized, and they are indeed synchronized, but only which I click on the folder in Outlook. For example, I have open the Microsoft Exchange Connection Status window. When I click a folder in Outlook to view it's contents, the status windows shows that that folder is being synchronized. I can go to Office 365 on the web and verify that everything has pushed to the cloud. However, if I don't click a folder nothing happens. It seems to be only synchronizing when I click a folder in Outlook. I have tons and tons of folders... so I really don't want to click them all. Surely there must be some way to force synchronization of everything? Or at least force synchronization of a folder and all its subfolders? |
| Vagrant not ready for SSH error on VirtualBox and Laravel Homestead Posted: 04 Apr 2022 08:25 PM PDT Vagrant Version: 1.6.3 VirtualBox: 4.3.14 Ubuntu 14.04 LTS 64 Bit
I have been on this for a pretty good while now and cannot figure this out. I have my public and private keys setup and they work. I know they are not the problem at they worked fine before I updated Ubuntu from 32 Bit to 64 Bit. I have uninstalled and reinstalled all software mentioned and still no fix. This is on a Laravel Homestead instance but it is happening on all my boxes, including the precise32 from vagrants home page. When I run vagrant ssh-config The error I am getting is The provider for this Vagrant-managed machine is reporting that it is not yet ready for SSH. Depending on your provider this can carry different meanings. Make sure your machine is created and running and try again. Additionally, check the output of `vagrant status` to verify that the machine is in the state that you expect. If you continue to get this error message, please view the documentation for the provider you're using.
This did not happend when I was on 32 Bit, but I had other issues when is what caused me to move up to 64 Bit. When I run vagrant up, it stops on this line: ==> default: Running 'pre-boot' VM customizations... ==> default: Booting VM... ==> default: Waiting for machine to boot. This may take a few minutes... default: SSH address: 127.0.0.1:2201 default: SSH username: vagrant default: SSH auth method: private key
Any thoughts on this would be welcomed. I hate that this is happening as I just recently released a podcast episode on how awesome development on Vagrant WAS as of right now, its sucking my time to try to get this in order. Thanks to all in advance! |
| Site-To-Site VPN with Quagga Posted: 04 Apr 2022 11:03 PM PDT Can Quagga broadcast a statically configured routes to all the computers in that network. Say for example I have network 10.0.1.0/16. In one of the PC in this network I am running Quaaga server and have configured a route there. Can this route be broadcasted to all the elements in this network? I was trying to find some online help. But, was not successful. I need this for the following scenario of mine - I am using SoftEther VPN Server to make a site to site VPN say between 10.0.10/16 and 30.0.1.0/16 and now the site to site VPN is established, I want to install a route on all the elements in that 10.0.1.0/16 to send the traffic to 30.0.1.0 through this VPN server. Can anyone please help me out with the Quagga configuration to do this. |
| Where to find the default status codes file for Apache in Ubuntu 12.04 Posted: 05 Apr 2022 01:04 AM PDT I am trying to customize all the status codes (error codes) in Apache - Ubuntu 12.04 LTS. The error message content I get on the browser for the error code 414 is: Request-URI Too Large The requested URL's length exceeds the capacity limit for this server. I went through the file: /etc/apache2/conf.d/localized-error-pages
to see the default file which shows this error, I found the below line: ErrorDocument 414 /error/HTTP_REQUEST_URI_TOO_LARGE.html.var
When I go through the file /usr/share/apache2/error/HTTP_REQUEST_URI_TOO_LARGE.html.var
I didn't find the same message viewed on the browser! How come? Where I can find the default message to edit it? I edited the above file and nothing changed on the browser! One more thing, how can I customize this error to fit two different websites on the server (each website has different custom_error_414 page) UPDATE: I removed the comments on the file localized-error-pages but the output didn't change, when I add any path in the file localized-error-pages like: ErrorDocument 414 /var/www/myproject/error.php
it doesn't work, but when I add a normal string like: ErrorDocument 414 "Long Request"
it does work! Please provide some codes and details on how to fix this issue and how to customize the 414 error for two websites. UPDATE Below is the output of wget -O- -S ... --2014-05-02 21:02:26-- http://localhost/error//HTTP_PRECONDITION_FAILED.html.var Resolving localhost (localhost)... ::1, 127.0.0.1 Connecting to localhost (localhost)|::1|:80... failed: Connection refused.

It didn't work :( While ErrorDocument 414 "Sorry, request is too long"
Worked out! How come? Why it doesn't redirect me to the error page? One more thing, I need to make for two websites two different pages, how can I achieve: ErrorDocument 414 sites1 ==> /var/www/myproject1/error.php ErrorDocument 414 sites2 ==> /var/www/myproject2/error.php
I want to put the error pages on my /var/www/project folder I would greatly appreciate if you can send me direct steps to follow as I am not experienced system admin and I can't find documentation about this on the internet, it is very poor. EDIT Thanks for the detailed answer, I have followed your steps but I have minor issues would appreciate your input. a. Below is the configuration file for the errors /etc/apache2/conf.d/localized-error-pages #Alias /error/ "/usr/share/apache2/error/" Options IncludesNoExec AddOutputFilter Includes html AddHandler type-map var Order allow,deny Allow from all LanguagePriority en cs de es fr it nl sv pt-br ro ForceLanguagePriority Prefer Fallback ErrorDocument 404 /error/HTTP_NOT_FOUND.html.var ErrorDocument 405 /error/HTTP_METHOD_NOT_ALLOWED.html.vr ErrorDocument 408 /error/HTTP_REQUEST_TIME_OUT.html.var ErrorDocument 410 /error/HTTP_GONE.html.var ErrorDocument 411 /error/HTTP_LENGTH_REQUIRED.html.var ErrorDocument 412 /error/HTTP_PRECONDITION_FAILED.html.var ErrorDocument 414 /error/HTTP_REQUEST_URI_TOO_LARGE.html.var

h. Tried from the browser: .../error/HTTP_REQUEST_URI_TOO_LARGE.html.var The same result as step 8 but the in the browser i. When I try placing huge request in the browser like: ...../site1/sj7xlekrjsuglkehgigl........., I get empty output on the browser and in the network (F12) I can see 414 error status How can I get this working? I need to give the code 404 for the 414 error and I need to use (include) the customized PHP pages on each website, which is /var/www/site1/not_found.php Edit 2 I have added the below in sites available, but if I put long URL in browser, it doesn't redirect me to index.php nor to not_found.php page. I need the long URL error (414) to direct me to 404 page :( I am really upset I can't find any help online. Error like 414 doesn't work like 404 easily, they built inside the system. 404 is very easy for me! But can't configure 414!!! ErrorDocument 404 /not_found.php <IfModule mod_rewrite.c> RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule>
For example in sites-available the below doesn't work ErrorDocument 414 /not_found.php |
| Why does sub_filter seem to not work when used in conjunction with proxy_pass? Posted: 05 Apr 2022 12:53 AM PDT Given the following configuration of nginx: server { listen 80; server_name apilocal; sub_filter "apiupstream/api" "apilocal"; sub_filter_once off; location /people/ { proxy_pass http://apiupstream/api/people/; proxy_set_header Accept-Encoding ""; } }
Sub_filter does not properly response parts of the response. Once I remove proxy_pass from the configuration, it works properly. A lot of folks with this problem end up having gzip compression from the upstream server. I've verified that my upstream server does not have gzip encoding turned on for its responses. But just in case, I've also used the proxy_set_header above to not accept gzip. Is there potentially something else I'm missing? |
| IUSR not able to access network resources Posted: 04 Apr 2022 10:01 PM PDT I have a website which access a network path for images including logos on the website. There is a virtual directory pointing to this network shared folder and I gave anonymous access to this virtual directory. This is to make sure that logos and images are available in login page, register page. Webserver is running windows 2008 R2 IIS 7.5 Fileserver is running windows 2008 R2 Both are on same domain network I use IUSR as anonymous user identity, and this works fine in UAT environment. Unfortunately not working on production environment. While troubleshooting I grant Everyone full access to network shared folder, still no luck. The images are not loading for anonymous users. Could anyone shed some light on this? |
