Nothing is accepted. I have test this on CentOS 5.5 and Fedora 14 both have the same result.

I have a VPS server with 512 MB memory. The php.ini is set so script memory limit = 16 MB. However, I have noticed in my top report, instances like the following:
Quote:
5484 coldclim 25 0 46476 32m 5920 R 0.0 6.4 0:00.93 php
The bold number of 6.4 is the % of sever memory this process is using. 6.4 % of 512 MB of memory is about 32 MB of memory, so it appears that this isn't being limited by php.ini. Am I correct? This leads to the next question: Is there some way to limit the amount of memory a single suphp process can use? (Basically, something like the setting in php.ini which limits suphp processes in the same way.)
I posted this in Networks but have had little luck in that forum lately...I haven't been able to connect via ssh to my media server at home. It's running Karmic (non-server version) and has sshd installed. I generated a rsa and dsa key pair and added them to the server in .ssh/authorized_keys and .ssh/authorized_keys2 by use ofcat key >> .ssh/authorized_keys(2)Changed sshd_config to only accept Keys and kept port 22, since I will port forward through router and make firewall exception down the line.I made an account on the server with the same name as my laptop.

I have ssh installed and running on my laptop(Debian Sequeeze). I can run "ssh localhost" without any problem. But for some reason I cannot connect to it from other computers. They all give "connection timed out". I can connect to these computers`s ssh servers but for some reason my laptop with Debian is not accepting any connections.

I have just set my self up a new LAMP server running php and mysql. I get the following error when trying to acces mysql databases through php Code: Could not connect: Access denied for user 'danhorni'@'localhost' (using password: NO) I am using a password I can login fine through phpmyadmin
View 1 Replies View RelatedSo on one of the Linux systems here (2.6 kernel if it matters), there's some weirdness regarding trying to ssh into the system. Basically, if you give it the wrong password on the first ssh attempt, it will give you two more attempts, but even if you give it the correct password, it still won't let you in on those subsequent attempts. (If you give the correct password on the first attempt, it will let you in.)
Example:
Code:
user1@machine1# ssh user2@machine2
user2@machine2's password: <wrong password>
Permission denied, please try again.
The system has sshd configured to use pam (i.e., UsePAM set to 'yes' in sshd_config), but I'm kind of a PAM dummy.
I have run a small webserver from my home computer and I can access it fine from computers on my local network, but cannot access it from other networks. I see in wireshark that the traffic is arriving at the computer and I have checked the firewall logs on my computer and nothing is being blocked(I use iptables as a firewall), and I can't see any reason why it shouldn't be working.
View 2 Replies View RelatedI have a samba server that I had setup using the default smbpasswd backend, and it worked fine. So long as I remembered to use smbpasswd/passwd to setup a user with a username and password matching the account name of a Windows 7 user, then that windows 7 user would be able to navigate the shares with their permissions correctly.I have switched over to using ldap, and: the console/ssh of the machine can correctly use any of the ldap logins getent passwd/group both show the complete listing my Windows 7 machines can all ping the samba server by its netbios name my Windows 7 machines all prompt for authentication if I type \MACHINENAME into explorerHowever, all attempts to access the shares now continually ask for you to enter your username/password, and then fails anyway.No errors appear to be generated on the server (unless I'm missing a log somewhere). Having hunted around on the web, I'm wondering if it has to do with generation of machine accounts (since it tries to access from MACHINENAMEUSER). Without ldap setup, I didn't need to worry about the machine name, but I'm thinking that maybe smbpasswd took care of this somehow.I use the smbldap-useradd tool to setup a user account, which appears to correctly setup the user in ldap, such as:
Code:
dn: uid=sharer,ou=Users,dc=intbus,dc=net
objectClass: top

I have installed talk on centos, turned it on by editing xinetd.d/talk and setting disable=no.I have restarted xinetd (service xinetd restart) and verified that talk is configured to start (chkconfig --status-all).what am i missing? shouldn't either port 517 or 518 respond to telnet? what else can i do to get talk running?

View 1 Replies View RelatedI installed a new server running CentOS 5.2. I have iptables and SELinux off. The new server will not accept incoming mail. It will send out fine.Our mail server redirects mail for it.help to it.[url]...- [url]....is this server. Any messages sent to this address get stuck in a deferred queue. The error message on each one (from the mail server admin console) is "connection to[url]... [10.9.10.202] - connection refused". I can ping [url].... from the mail server.
This seems like a firewall issue, but it is off. Is there some configuration file I need to change to allow incoming mail? Or is there some test I can run on the new server to further troubleshoot what is going on
Having a problem with tftpd on CentOS 5.5. I am only able to download files from the localhost address.
I have checked iptables (by adding rules and by turning the firewall completely off -- nothing changes) and enabled tftpd logging (by adding -v to the server_args section in xinetd.d/tftp) and I DO see the request coming in, but no response from the daemon. I've also tried upping the verbosity by adding multiple -vs and/or --verbosity 10 to the mix, but all I ever see is the initial request come in, nothing more. I've even tried running the daemon in foreground mode with -L but I get no verbosity then.
I have a problem with both genisoimage and mkisofs. Both of them are limited to 8 characters. There are very many options for them. Which one would remedy the issue?
View 3 Replies View RelatedI'm writing a shell script which aims to create a safe gtared (xxx.sql.gz) copy of MySQL databases.This script is planned to be Cron-Jobed.
Well, what I need to add to this shell, is something that limit CPU usage for the whole process (just in case if the database being generating is a huge one.)So, after few time of googling I found couple of solutions:
- Using cpulimit.
I tried to place the code in Position(1) and Position(2) but it didn't seem to be working fine.. Any idea about the right use?
And the other Solution is:- Using nice.
Well, assuming I named my shell script (sqlbacker)..
Finally, this is my first time I ever write a shell, so correct me if somewhere I made a mistake :-)
(The script itself works perfectly)
I currently use cp to backup data. I prefer it over rsync. I use the -b switch to make a backup of data and recently found you can use --backup=t to create numbered backups.Using --backup=t means that I could end up having 100 versions of a file if I change it 100 times. With the -b switch I will only ever have 2 versions. Is it possible to limit the numbered backups to 5 for example? So I would only ever have 5 versions?
View 2 Replies View RelatedThere's a disfunctional process eating copious cpu time.Is there a way to effectively assign it a high nice value? I need to do this whenever it runs, for whatever reason, and I can't be bothered to track down all the scripts and scenarios that cause it to run and change the script to use nice. And I can't be bothered to manually run renice whenever I notice that it's running.
I want the OS to automatically assign a high nice value to this process, perhaps based on the processes name. Is this possible?Presumably, a cron job could run every 5 minutes and run "renice" on every process matching a given name, but I'm hoping for a solution with more finess.

Is my default keyring different from my password, and how do I find out what it is/change it
However I just built a 10.10 server, installed webmin, vmware, and the server is working perfectly. I configured my bind 9 server using the latest webmin and on the server everything resolves perfectly to both the internet and lan. I have it set to 127.0.0.1, the server ip address is 10.1.50.25. However, it will not accept dns client queries in which they cannot resolve to the lan or internet. I have the dhcp giving out the dns server 10.1.50.25. NSLOOKUPS from the client show query refused. I know there has to be some setting or config that will allow clients to query but I am not able to locate it, and I am not totally knowledgeable of named.conf and been all through the webmin module and configuration settings.

I have QPopper and Sendmail setup on a Red Hat server, they both seem to be running ok and listening on usual pop and smtp ports 25 and 110.
QPopper is running through xinetd and the config file is as follows
Code:
service pop3
{
disable = no
flags = REUSE
socket_type = stream
wait = no
[Code].....
The problem is I get an error in the maillogs when trying to send mail from a PC on our local domain about the canonical client name which is to do with reverse dns. I understand this can be turned off at runtime of qpopper but nowhere seems to detail how to do this, apart from -R flag at runtime but as it is running through Xinetd I am not sure where to put it.
A few more details on the problem, if I VPN onto our network from my home desktop I can send mail fine. Receiving mail is also no problem, it is just sending. I have setup only our local domain in the access file for sendmail.
Have tried to setup email aliases in sendmail so I can have multiple address pointing to one linux login. However none of the aliases seem to be accepting mail.
I get the following error message when trying to send to them.
I have tried restarting sendmail, have mapped the /etc/mail/virtusertable across to virtusertable.db with the following command.
Code:
Output of sendmail -bv is as follows and looks correct.

I did a clean install of OpenSuse 11.3 a couple of weekends back. Everything is working great except the SSH server.Once I installed ssh, it appears to accept my connection, allows me to log in, and then freezes Putty, not allowing me to type anything into the terminal.If I wait several minutes, I'll get a message saying that the connection was closed. After that, the server won't accept connections.Sometimes it'll start accepting connections again, but after a while, the connection will close on its own. Other times, I will be unable to get a connection until I restart the server.If you guys needs any more information, please let me know. What could be causing this odd behavior?
