I have two servers running Linux 2.6.9 kernel.When i telnet to server1 , the telnet will be disconnected only after 3 login failures. While, when i telnet to server2, telnet will be disconnected after the first login failure.expect server2 to behave the same way as server1 when telnet is executed.Kindly tell me where i should tweak my servers so that i could achieve what i expect.

a user called, cannot login - forgot the password - common case ( 200 user system )- but this one seems to be a bit different:
user tries to log in via ssh - login/passwd incorrect,
via telnet - no problem
tried a few different users on ssh - no problem... It seems the access denied applies to just a single, standard user account - only via ssh, all other users are able to login... tried also to change the passwd, no difference. beside re-creating the account, can you think about anything else? system: RHEL AS3, 2.4.21-51ELsmp

I have just a one line script that runs telnet, and even thoughI've looked around I thought maybe someone could just tell me if there is a way to automatically login to the telnet server without having to type it in everytime. It's more of a hassle type of thing, but no matter what I've tried, I can't get anything to work.
View 5 Replies View RelatedIf I only want to let a user be able to login via telnet a max number of times equal to 2 how would I go about doing this?I have found this little tid bit:per_source = 2but that only allows 2 connections from the same source (i.e. network) and that would not work. For some reason our telnet sessions are not dying off after a user has shutdown their PC and then the next time they login it adds another telnet session.

I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:
Code:
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

Is there a way to show or count how many CPU instructions a particular process is using or uses?
In my work we develop a web application and I'm responsible of maintaining the web server.
The app lets you handle data online so each client that uses the web application has a folder associated to it, where his data is stored. (/var/www/html/test) for example.
The idea is to get how many CPU instructions the httpd process for that particular folder is having. Is there a way to do this?
Is there a command to count inodes with in a directory?
I know I can see total inode usage with:
df -i
And I know I can find total number of files with:
find ./ |wc -l
But how can I find inodes? As files over 8kb (if using the default partitioning of 1 node over 2 4kb blocks) would take up more than 1 inode.
I just setup a server using Ubuntu 10.04LTS Desktop edition. I am a novice in these things. I was able to setup the SSH server and it works from outside my LAN quite well. I can telnet to it also with 22. I have then setup an email server. I can do telnet to it from the server itself but from the internet it just times out.
I did netstat -nlp and it shows that it is listening to port 25. I have port forwarding for 25 enabled on the router. I cleaned up all the rules of iptables and iptables -L shows everything is accepted.

I'm trying to test smtp connectivity to my postfix configuration and I can telnet to port 25 from the computer itself but cannot from the outside. I get a connection refused error message.

View 14 Replies View RelatedI have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues.
The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again.
How to force all TCP connections to resend data without delays in GNU/Linux?
I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.
View 2 Replies View RelatedI'm using fwrite to write into a file stored in a normal USB flash drive. My question is: if for example a sector is damaged, does fwrite try with another one before getting me a result? If not, If I recall fwrite, will it try with a different one or with the same?

Previously I had posted a question on how to make it run every 7 minutes between 7 and and 11pm.However now I found out what I really need is every 7 minuted between 7:30 and 11pm BUT it has to be every 7 minutes, it cannot reset itself on the top of every hour, so the */7 wont work.How can it that it will be every 7 minutes, so it will go at 7:30, 37,44,51, 58, 8:05, etc..
