When ever I restart ssh
Quote:
/etc/init.d/ssh restart
I see following line in auth.log
Quote:
sshd[5678]: error: Bind to port 22 on :: failed: Address already in use.
That is a headless server. What does the above line signify or tell and why am I seeing that? Ubuntu 10.04 64 bit server edition
Lately I have been receiving this in my auth.log file. It seems to be repeating over and over, and I didn't know if was anything normal or something I should be worried about...
Code:
As far as I understand ssh runs on port 22 but in my /var/log/auth.log I see

why is this logged 48504 different than ssh port 22?
I have succesfully set up authentication manually in Ubuntu so users can log on with Windows Active Directory accounts and have their network drives mapped automatically using pam_mount.
Please note due to the setup I can't make any changes to the Windows 2k3 server.
If a user wants their password reset I can change it to a generic password. When they next log on to a Windows computer with the generic password it will automatically ask them to change it to something else.
Is there anyway to get this to work with Ubuntu 10.10? At the moment when logging onto Ubuntu with an account that is in this state the message Please change your password appears, it then proceds to log on without prompting to change the password and natually it won't map the drives etc.
On Ubuntu 10.04 with x11Vnc server, if the screen requires logon (such as if locked or upon reboot), through the VNC terminal, I always get authentication error (incorrect password). Sitting at the keyboard, I can logon just fine. Once logged on, I can access everything through VNC just fine.
Error in auth.log (username = bob):
unix_chkpwd[3926]: password check failed for user (bob)
gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): authentication failure; logname= uid=1000

I'm a bit lost with the PHP/Sendmail configuration, maybe somebody could help me getting back on the right track. Following situation:
Postfix:
* accepts smtp on port 25 but from his own domains. Some policy and spamchecks through amavisd are made.
* accepts submission on port 587 and 465 from authenticated users only. Quota and spamchecks prevent outgoing spam.
So I'm enforcing a very strong outgoing spam-policy but the users are still able to use the php mail() function to send spam through the /usr/sbin/sendmail command.
My users have access to their own php.ini so my idea was to somehow enforce the delivery through the local postfix on port 587 or 465 and just let them enter their user/pass in their php.ini. (I suppose, their might be a cleaner-solution ).
Unfortunately, my configurations like smtp_host, port, user etc. are getting ignored if the sendmail_path line is active. But if I comment this line out, php just uses the default, which is the same as configured in the sendmail_path line - so it's active whether i use the line or not (setting it to an invalid command breaks the mail() function completely).
how can I enforce my anti-spam policy on the php mail() command?For my ssh users I just blocked the outgoing connection to localhost on port 25 which seems to work so far, but somehow the postfix-sendmail-wrapper just ignores this.
I'm trying to config a customer's samba server to use a MS 2003 SBS for auth. The samba is for file sharing only config'ed with disk quota's. Currently the samba is config'ed for auth = Users. But I want a central point for user auth, and since they already have the sbs in place, I'd like to use that.

I login as normal user. I can 'su root' fine - password authenticates. However, If I try to run System->Administration->Users/Groups, when it asks for root password, it is rejected. When I run updater, it reports failure to authenticate, but doesn't even ask for root password beforehand. Is there a cached password someplace?

View 1 Replies View RelatedI recently installed Server 10.10 64-bit. After installation, I set up my config file (/etc/samba/smb.conf), and tried to restart Samba:
Code:
/etc/init.d/samba restart
There was nothing to restart though - the file /etc/init.d/samba wasn't there!
Purged the package and re-installed. Tried reformatting and adding Samba as a pre-installed package. Trying to find the server guide for 10.10, but no dice. Did something change for Samba in 10.10?
This was working perfect and all of a sudden stops. Now when I try and start this service it simply hangs. I have searched and found a ton of reasons why this could be. No fix yet as worked.
View 8 Replies View RelatedI am running a headless home file server with ssh, samba, webmin and webgui for Transmission. It was all working fine on my lan until I tried to set ssh to listen on a different port (I read it was safer to do so if you wanted access from the internet). Now I cannot ssh into my server and as far I can tell using webmin the ssh process is no longer running and I cannot restart it. I have restored my unmodified sshd_config file. After restoring my original config file and rebooting I am back and working.
View 2 Replies View RelatedI've decided to toy around with LVM and mdadm this weekend. I can get everything working, and all is well, until I restart. After that, I no longer have any /dev/md0 device, which during the auto mount process, causes an error. I've looked through several HOWTOs, as well as the LVM/mdadm man pages, and I believe I've tracked it down to mdadm's "assemble" that is needed (so that LVM can see the md0 device).
Not exactly sure how to go about having this occur during the boot process to ensure that the LVM mapped drive is available for when fstab is read. In case it helps this is a base install of 10.10 server 64. I have four drives, the first is used for the OS and is not in the RAID array (nor LVM). The second and third are RAID1 (/dev/md0) and there is a volume group associated with /dev/md0. The last is a LVM, but not RAID, and it has its own volume group.
I've installed Ubuntu server and got everything setup pretty well.My problem is apache.I put my website in /var/www and changed the security on the files to allow them to be executed by other, which is what I finally discovered was my first problem (access denied). But now whenever.I go in and edit my page, the changes aren't reflected on the site unless I completely restart apache.I know I'm doing something wrong because I used to pay for a host and every time I edited a page, it was instantly updated on the site. Could one of you gurus tell me where I screwed up?

Here's the problem -- DHCP wont start and throws the error "Can't create PID file /var/run/dhcpd.pid: Permission denied." Somewhere I found a post that indicated that the following corrected the issue (I dont really know why):
ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid
dhcpd3 -cf /etc/dhcp3/dhcpd.conf eth1
When I do the above DHCP will start (in theory, at least no erros are thrown). But if I ask DHCP to restart, it will stop, but not restart. And the error is "No subnet declaration for eth1 (192.168.3.2)"

I like to work on stuff from remote locations and have set it up to be accessed it with the external IP address by my laptop.The problem is that if I'm at a remote location and tell it to restart, when it boots up it won't log me on unless I enter the password, but I can't remote access it until I'm logged in.So, is there a command or script that I can run that will tell it to restart and bypass entering a login password?I'm only looking for something to bypass it ONCE per command/script, NOT to disable my password.

I'm setting up an ubunutu server (tomcat, mysql etc) which has been going very smoothly I must say. I plan to do manual updates over ssh using "sudo apt-get update" and "sudo apt-get upgrade" but I believe sometimes these update will need a complete machine: how can I tell if I need to reboot the server after an update _using the command line_?

When using the movement keys (arrows and numpad) I get "[" brackets and "C"s, if I hold down or push down on the key hard a list of errors and text comes up, usually involving something that says something like:"Mount disabled" or "____ disabled press CONTROL-X to restart the shell"Similair problems are also found in vi (when in insert mode).I have been plagued with text editor problems and have need several reboots just to get out of a file, often because it just flat out stopped responding to keyboard commands.
bit of a server noob having built a server to hold a php website for a client hosting at home, I have some experience, but VERY limited and don't speak fluent server.My problem is that overnight each day apache on my clients server stops responding. I can still access via putty / webmin.The best I can see it, it seems that apache 2 opens too many child processes and chokes the system. My reasoning for this is:-Though I have max child set to 20 with a keep alive of 30 there are dozens of child processes 'apache2 -k start' running, some of which were started 9.5 hours ago.
-I can stop apache, though that doesn't kill these child processes. I can terminate the parent process which does kill the child processes, however restarting apache after killing the child processes results in a system crash. Rebooting the server remotely after apache has stopped responding also results in a server crash. That is NO response on any port.I would be happy to display any pertinent server config/logs etc if anyone can help me troubleshoot this?
I just rented a godaddy dedicated, the ubuntu variety comes loaded with 8.04...(& I need PHP 5.3)Followed the directions here: URL...I did have to change my sources.list, everything after that went as expected (not like i'd know what to expect)At one point it asked if I wanted to update my grub/menu.lst to the release version, or use my old one, I updated it.Once the upgrade completed, I checked the menu.lst again to ensure it was gonna boot 10.04 (as warned by the guide)However once I sent reboot, I couldn't SSH back in, I waited 5m, 15m, tried again, still couldn't SSH then I had the server power cycled via my godaddy control panel, and still nothing, attempts on port 22 timed out & other ports were refused.
I think I overlooked something because, from what I've read here and there this is technically possible, I also just found this guide here:URL...The first user comment (above link/guide) seems to have a tip for what I'm trying.Anyways had the server re-provisioned via my control panel & I'm about to try again, only this time. uh, check the SSH settings post upgrade/pre restart?

View 6 Replies View RelatedI have observed a problem twice now with Apache trying to restart but hanging somewhere in the process. This happens after a power failure; the machine comes back just fine, but not the web server. The machine is on a UPS, but occasionally it runs out of "juice" before someone can get to it (we have a generator for emergencies). When this happens, a ps indicates about three processes running that are trying to start Apache, but they just sit there - this time for three days since the power failure was on a Friday. I can fix this by killing those processes and doing an Apache restart - but that takes human intervention, which is not acceptable.
I suspect this may have to do with SSL, since when I do a manual restart it asks me for the SSL password. There must be some way around this so the system can recover on its own. This system's web site runs under SSL since it maintains medical information that must by law be protected. But it also could be life-threatening to someone if the system can't come back and as a result a person can't get help.
So I would appreciate some guidance as to what I could change that would allow for system recovery without intervention. I'm happy to provide any configuration file info, if you tell me where to look.
