  • chroot'ing SSH home directories, shell problem.

    - by Hamza
    Hi folks, I am trying to chroot my SSH users to their home directories and it seems to work.. in a strange way. Here is what I have in my sshd_config: Match group restricthome ChrootDirectory %h The permissions on the user directories looks like this: drwxr-xr-x 2 root root 1024 May 11 13:45 [user]/ And I can see that the user logs in successfully: May 11 13:49:23 box sshd[5695]: Accepted password for [user] from x.x.x.x port 2358 ssh2 (with no error messages after this) But after entering the password the PuTTY window closes down. This is a wild guess, but could it be because the user's shell is set to /bin/bash and it can't execute because of the chroot? If so, could you give me pointers on how to fix it? Would simply copying the bash binary into user's home directory and modyfying the shell work? How would I deal with the dependencies, ldd shows quite a few of those :) Comments/suggestions will be appreciated. Thanks.

  • Too many TIME_WAIT state connections!

    - by Hamza
    I've been reading about this everywhere all day, and from what I've gathered, TIME_WAIT is a relatively harmless state. It's supposed to be harmless even when there's too many. But if they're jumping to the numbers I've been seeing for the past 24 hours, something is really wrong! [root@1 ~]# netstat -nat | awk '{print $6}' | sort | uniq -c | sort -n 1 established) 1 Foreign 12 CLOSE_WAIT 15 LISTEN 64 LAST_ACK 201 FIN_WAIT2 334 CLOSING 605 ESTABLISHED 816 SYN_RECV 981 FIN_WAIT1 26830 TIME_WAIT That number fluctuates from 20,000 to 30,000+ (so far, the maximum I've seen it go is 32,000). What worries me is that they're all different IP addresses from all sorts of random locations. Now this is supposed to be (or was supposed to be) a DDoS attack. I know this for a fact, but I won't go into the boring details. It started out as a DDoS and it did impact my server's performance for a couple minutes. After that, everything was back to normal. My server load is normal. My internet traffic is normal. No server resource is being abused. My sites load fine. I also have IPTABLES disabled. There's an odd issue with that too. Every time I enable the firewall/iptables, my server starts experiencing packet loss. Lots of it. About 50%-60% packets are lost. It happens within an hour or within a few hours of enabling the firewall. As soon as I disable it, ping responses from all locations I test them from start clearing up and get stable again. Very strange. The TIME_WAIT state connections have been fluctuating at those numbers since yesterday. For 24 hours now, I've had that, and although it hasn't impacted performance in any way, it's disturbing enough. My current tcp_fin_timeout value is 30 seconds, from the default 60 seconds. However, that seems to not help, at all. Any ideas, suggestions? Anything at all would be appreciated, really!

  • Linux route add between static LAN and Wifi Gateway

    - by Hamza
    I have two local machines connected to each other via wired ethernet and one of those machines is also connected to a wifi network which provides internet access. A pseudo-graphical representation of the topology is as follows: (PC2)----------(PC1)---------(Wifi Gateway) 192.168.2.x 10.0.0.x The configuration on PC2 is: iface eth0 inet static address 192.168.2.2 network 192.168.2.0 netmask 255.255.255.0 gateway 192.168.2.1 ...and the configuration on PC1 is: iface eth0 inet static address 192.168.2.1 network 192.168.2.0 netmask 255.255.255.0 gateway 192.168.2.1 On PC1, I've added a default route for wlan0 as I couldn't access the internet otherwise: route add default gw 10.0.0.1 wlan0 And also tried setting the gateway for the 192.168.2.x network using: route add -net 192.168.2.0 netmask 255.255.255.0 gw 10.0.0.1 But I still can't access internet from PC2. Edit I don't have access to the wifi gateway.

  • mdadm - Recovering a 'split' RAID1 array

    - by Hamza
    I have two drives that used to be part of a single RAID1 volume but it appears that one of them went offline for some time, something I've noticed just now when I rebooted my system. I now seem to have two RAID volumes, as reported by: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md126 : active raid1 sdc[1] 2096116 blocks super 1.2 [2/1] [_U] md127 : active (auto-read-only) raid1 sdb[0] 2096116 blocks super 1.2 [2/1] [U_] unused devices: <none> Not exactly sure where to go from here. How can I merge and re-sync these volumes without data loss? Thanks.

  • Java Implementing htonl

    - by Hamza Yerlikaya
    I am communicating with a server, each message sent to the server has to be padded with the length of the message, unsigned int len = htonl(msg.size()); In C running the length through htonl and padding the message works, in Java AFAIK byte order is already in network order so I assumed all I have to do is write the string length before the message to the stream, but this does not work am I missing something? stream.write(msg.length()); stream.write(msg.getBytes()); Stream is an OutputStream.

  • Circular Dependency of Navigation Control in iPhone

    - by Taimur Hamza
    Hi everyone , In my view this is one of the strangest problem i have ever come across in iPhone app development. Let me explain the scenario , i have main screen 'A' on which i have a Button that directs me to another Screen say 'B'. Now on Screen 'B' i have a feature in which user can send a mail to his friend for promotion purpose e.g a user wishes to tell a frnd about this app so i used MFMailComposeViewController and a view is generated where the user types the address and click send ( subject and body of mail is automatically generated ). After sending the mail a new view opens say screen 'C' and here i want to give the user the options . 1. Go to Screen 'A' ( which is main screen of the app ) 2. Go back to Screen 'B' ( from where the user requested to send a mail to his frnd ). Now the strange part i cannot declare the variables ( Screen 'A' and 'B' ) of both these files here at in header file of screen 'C' . Even when i declare the header file at the top it generates an error. The variables can be easily be declared and used for other screens but not for these 2 screens. Can anybody please explain wats the problem.? this the text of the error "/Users/admin/Documents/AppName/Classes/A.h:42: error: expected specifier-qualifier-list before 'B'" Thanks Guys ! Taimur

  • radgrid insert using radwinow

    - by Hamza
    Hello Everybody, The company details page in my system has a user control to show the founders of the company, that user control represents the founders by using a Rad Grid and three buttons for insert/edit/delete founders, the founders grid is being bind by using a WCF service. the insert button calls a javascript method that opens a Rad Window in which the user can insert the data for a new founder my problem is: in the Add Founder Rad Window I shouldn't save the new founder in the database, when I press Add the Rad Grid should be closed and the new founder should be added to the founders Grid's datasource, and then the grid should be bind again the questions is: what is the best way to do that, I don't want to use sessions nor json, I tried to use another wcf service which takes two parameters: reference to the grid and the new founder, and in this wcf service I get the old datasource then add the new founder to it and finally rebind the grid again, but I have faced some problems like how can I send the reference to the grid from javascript method to a WCF service, also if I add more than one founder how can keep track of the new founders and the original datasource if any of you can lead me to an example similar to my case this would be very much appreciated, also any comments and feedback are most welcomed

  • Guiding a Robot Through a Path

    - by Hamza Yerlikaya
    I have a field filled with obstacles, I know where they are located, and I know the robot's position. Using a path-finding algorithm, I calculate a path for the robot to follow. Now my problem is, I am guiding the robot from grid to grid but this creates a not-so-smooth motion. I start at A, turn the nose to point B, move straight until I reach point B, rinse and repeat until the final point is reached. So my question is: What kind of techniques are used for navigating in such an environment so that I get a smooth motion? The robot has two wheels and two motors. I change the direction of the motor by turning the motors in reverse. EDIT: I can vary the speed of the motors basically the robot is an arduino plus ardumoto, I can supply values between 0-255 to the motors on either direction.
