• Apache error "No address associated with hostname" on Arch Linux (ZMLarch)

  - by Eedoh

  I'm trying to set up video surveillance system using IP cameras and ZoneAlarm on Arch Linux. I set up fixed IP address, I've managed to get streams from cameras, etc. However, after restart of the machine, I cannot start Apache again. I checked configuration of rc.conf, and saw that static IP configuration has been deleted, and also secondary nameserver in resolv.conf. Tried to re-write these with correct parameters, but now with no effect. This is tail of my /var/log/httpd/error_log file, after /etc/rc.d/httpd restart attempt [Fri Jan 29 04:20:45 2010] [alert] (EAI 5) No address associated with hostname: mod_unique_id: unable to find IPv4 address of "zmhost" Configuration failed Anybody have an idea on how could I fix this?

• linux refused to mount a valid partition

  - by greg

  My setup is a linux box with 1 partition used thought LVM - has been working for years. I add a freeze and after the reboot the partition cannot be mounted: mount -r -t ext3 /dev/pve/data /mnt/pve-data mount: wrong fs type, bad option, bad superblock on /dev/mapper/pve-data, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so However fsck doesn't see any problem with it: fsck.ext3 -fp /dev/pve/data /dev/pve/data: 3024076/60366848 files (0.6% non-contiguous), 156921642/241435648 blocks There's nothing in dmegs nor the syslog. I'm puzzled, what's wrong with my partition? Thanks in advance greg debian 5.0.10 LVM 2.02.39

• Linux Flash Player with 2 Monitors: always full-screen on primary monitor

  - by CarlF

  My setup at home uses a laptop, with a larger external monitor in addition to the built-in LCD panel, which is primary. I can see the larger monitor from the rest of the room and use it as my TV, for playing DVDs and various types of web video. However, it isn't ideal for Flash video. For instance, if I watch a video from Hulu or any other Flash-based site, I can expand it to full-screen mode. However, no matter which monitor the browser window is on, the full-screen mode is always on the laptop LCD panel, which is both too small and not visible from most of the room. Does anyone know of a way to force the Flash video to play full-screen on the monitor I select instead of the primary? My video chipset is NVidia, using kernel 2.6.31 (Ubuntu). Thanks.

• arp problems with transparent bridge on linux

  - by Mink

  I've been trying to secure my virtual machines on my esx server by putting them behind a transparent bridge with 2 interfaces, one in front, one at the back. My intention is to put all the firewall rules in one place (instead of on each virtual server). I've been using as bridge a blank new virtual machine based on arch linux (but I suspect it doesn't matter which brand of linux it is). What I have is 2 virtual switchs (thus two Virtual Network, VN_front and VN_back), each with 2 types of ports (switched/separated or promiscious/where the machine can see all packets). On my bridge machine, I've set up 2 virtual NIC, one on VN_front, one on VN_back, both in promisc mode. I've created a bridge br0 with both NIC in it: brctl addbr br0 brctl stp br0 off brctl addif br0 front_if brctl addif br0 back_if Then brought them up: ifconfig front_if 0.0.0.0 promisc ifconfig back_if 0.0.0.0 promisc ifconfig br0 0.0.0.0 (I use promisc mode, because I'm not sure I can do without, thinking that maybe the packets don't reach the NICs) Then I took one of my virtual server sitting on VN_front, and plugged it to VN_back instead (that's the nifty use case I'm thinking about, being able to move my servers around just by changing the VN they are plugged into, without changing anything in the configuration). Then I looked into the macs "seen" by my addressless bridge using brctl showmacs br0 and it did show my server from both sides: I get something that looks like this : port no mac addr is local? ageing timer 2 00:0c:29:e1:54:75 no 9.27 1 00:0c:29:fd:86:0c no 9.27 2 00:50:56:90:05:86 no 73.38 1 00:50:56:90:05:88 no 0.10 2 00:50:56:90:05:8b yes 0.00 << FRONT VN 1 00:50:56:90:05:8c yes 0.00 << BACK VN 2 00:50:56:90:19:18 no 13.55 2 00:50:56:90:3c:cf no 13.57 the thing is that the server that are plugged in front/back are not shown on the correct port. I suspect some horrible thing happening in the ARP-world... :-/ If I ping from a front virtual server to a back virtual server, I can only see the back machine if that back machine pings something in the front. As soon as I stop the ping from the back machine, the ping from the front machine stops getting through... I've noticed that if the back machine pings, then its port on the bridge is the correct one... I've tried to play with the arp_ switch of /proc/sys, but with no clear effect on the end result... /proc/sys/net/ipv4/ip_forward doesn't seem to be of any use when using a bridge (seems it's all taken care of by brctl) /proc/sys/net/ipv4/conf//arp_ don't seem to change much either... (tried arp_announce to 2 or 8 - like suggested elsewhere - and arp_ignore to 0 or 1 ) All the examples I've seen have a different subnet on either side like 10.0.1.0/24 and 10.0.2.0/24... In my case I want 10.0.1.0/24 on both side (just like a transparent switch - except it's a hidden fw ). Turning stp on/off doesn't seem to have any impact on my issue. It's as if the arp packets where getting through the bridge, corrupting the other side with false data... I've tried to use the -arp on each interface, br0, front, back... it breaks the thing altogether... I suspect it has something to do with both side being on the same subnet... I've thought about putting all my machine behind the fw, so as to have all the same subnet at the back... but I'm stuck with my provider's gateway standing at the front with part of my subnet (in fact 3 appliance to route the whole subnet), so I'll always have ips from the same subnet on both side, whatever I do... (I'm using fixed front IPs on my delegated subnet). I'm at a loss... -_-'' Thx for your help. (As anyone tried something like this? from within ESXi?) (It's not just a stunt, the idea is to have something like fail2ban running on some servers, sending their banned IP to the bridge/fw so that it too could ban them - saving all the other servers from that same attacker in one go, allowing for some honeypot that would trigger the fw from any kind of suitable response, and stuffs of the sort... I am aware I could use something like snort, but it addresses some completely different kind of problems, in a completely different way... )

• Windows7 NFS with linux server

  - by Vitaly

  Hi. I have an Ubuntu server and want to access its web folder (/var/www). What I done: installed nfs-kernel-server, nfs-common and portmap (as in faq) Setted up /etc/exports: /var/www 192.168.1.0/255.255.255.0(rw,no_roow_squash,async,subtree_check) Then: sudo exportfs -ra Then: sudo /etc/init.d/nfs-kernle-server restart I checked, if all works on same machine: sudo 192.168.1.101:/var/www /mnt/test Then accessed /mnt/test and seen that all data present and all ok. Next, I tried to connect this folder to windows7 using NFS client: First, I checked, that linux exported path successfully: showmount -e 192.168.1.101 /var/www 192.168.1.0/255.255.255.0 All ok, go to mount: mount -o anon 192.168.1.101:/var/www z: Console said, that all success.. but. I cant access drive Z (drive exists in the system and point to right folder). When I try to access drive Z my Explorer just going to sleep and then say that timeout expired. Help me please.

• Linux laptop encryption

  - by kaerast

  What are my options for encrypting the /home directories of my Ubuntu laptops? They are currently setup without any encryption and some have /home as a separate partition whilst others don't. Most of these laptops are single-user standalone laptops which are out on the road a lot. Is ecryptfs and the encrypted Private directory good enough or are there better, more secure, options? If somebody got hold of the laptop, how easy would it be for them to gain access to the encrypted files? Similar questions for encrypted lvm, truecrypt and any other solution I may not be aware of.

• security issue of Linux sudo command?

  - by George2

  Hello everyone, 1. I am using Red Hat Enterprise 5 Linux box. I find if a user is in /etc/sudoers file, then if the user run command with sudo, the user will run this command with root privilege (without knowing root password, the user runs sudo only need to input the user's own password in order to run a command with sudo). Is that correct understanding? 2. If yes, then is it a security hole? Since users other than root could run with root privilege? thanks in advance, George

• Arch Linux with an nginx/django setup refuses to display ANYTHING

  - by Holland

  I'm on Amazon Ec2, with an Arch Linux server. While I truly am loving it, I'm having the issue of actually getting nginx to display anything. Everytime I try to throw my hostname into the browser, the browser states that it's not available for some reason - almost as if the host doesn't even exist. One thing I'd like to know is, how can I get this up and running? Is there a specific arch linux configuration I have to do to make it web accessible? I have port 80 open, as well as port 22. I've tried using gunicorn, python-flup, and nginx. Nginx Config user http; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name _; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; #charset koi8-r; location ^~ /media/ { root /path/to/media; } location ^~ /admin-media/ { root /usr/lib/python2.7/site-packages/django/contrib/admin/media; } location / { root /path/to/root/; fastcgi_pass 127.0.0.1:8080; fastcgi_param SERVER_NAME $server_name; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param QUERY_STRING $query_string; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_pass_header Authorization; fastcgi_intercept_errors off; fastcgi_index index.html; index index.htm index.html; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /etc/nginx/html/50x.html; } } # server { # listen 80; # server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; # location / { # root html; # index index.html index.htm; # } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # #error_page 500 502 503 504 /50x.html; #location = /50x.html { root html; #} # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} #} # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} } I can't quite tell if it's a server issue or a configuration issue: I've followed so many guides now I can't even count them all. The thing is that Django itself is working fine, and my permissions to the document root of the where the site files are stored is 777. Ontop of that, I have a git repo which works perfectly fine, and django, python, and runfcgi all start without issues. The same goes for gunicorn, when I do a gunicorn_django -b 0.0.0.0:8000 in my document root. Here is my output from that: 2012-04-15 05:17:37 [3124] [INFO] Starting gunicorn 0.14.2 2012-04-15 05:17:37 [3124] [INFO] Listening at: http://0.0.0.0:8081 (3124) 2012-04-15 05:17:37 [3124] [INFO] Using worker: sync 2012-04-15 05:17:37 [3127] [INFO] Booting worker with pid: 3127 As far as I know, everything seems fine, as well as error.log and access.log for nginx. The access log is completely blank, for that matter. I just feel lost here; what would be a step in the right direction to bebugging an issue such as this?

• How to Set Linux Bonding Interface to Gigabit

  - by Kyle Brandt

  I have enabled Linux active backup mode bonding. Each interface is a gigabit interface, but the bond interface seems to end up at 100 Megabit: bonding: bond0: Warning: failed to get speed and duplex from eth1, assumed to be 100Mb/sec and Full. ... bnx2: eth0 NIC Link is Up, 1000 Mbps full duplex, receive & transmit flow control ON ... bonding: bond0: backup interface eth1 is now up ethtool apparently can't provide info on bond: sudo ethtool bond0 Settings for bond0: No data available So does this mean I am operating at 100 or 1000 Megabit (My guess is 1000)? If it is only 100, what options in the ifcfg scripts or the modprobe bonding options do I need to sett to make it 1000?

• Linux - How to control Winbind Authentication cache timeout

  - by cybervedaa

  I have configured my linux machines (running CentOS 5.2) to authenticate against a Windows server running Active Directory. I have even enabled winbind offline logon. Everything works as expected, however I'm also looking to impose a TTL for the winbind authentication cache. So far all I found was the below snippet from the samba documentation winbind cache time (G) This parameter specifies the number of seconds the winbindd(8) daemon will cache user and group information before querying a Windows NT server again. **This does not apply to authentication requests**, these are always evaluated in real time unless the winbind offline logon option has been enabled. Default: winbind cache time = 300 Clearly the winbind cache time parameter does not control the cache TTL for authentication requests. Is there any other way I can implement a cache timeout for winbind authentication requests? Thank you

• Cannot dual boot Windows 7 after installing Linux Mint

  - by shva

  I first installed Windows 7. /dev/sda1 was the system reserved partition for Win 7, and /dev/sda2 was the C partition. Then I installed Linux Mint. After that, when I started the computer, I could see the "Windows 7 (/dev/sda1)" was listed in the end of boot menu, but I could boot into Windows 7. The only thing I can think of is I might make a mistake in choosing the place the grub was to be installed: I chose /dev/sda1 rather than /dev/sda by default. Can anyone provide any advice? Thanks so much!

• High CPU usage on Linux machine

  - by user305210

  I have a piece of java code running on two different machines, but on one of the linux machines, the code uses alot of CPU (close to 100% cpu usage). On the other machine the same code uses less cpu (under 3 to 4%). The machine where cpu usage is high, is a more powerful machine, more CPU and and more memory. This has started happening recently and performance on the machine with high cpu usage has degraded significantly. I am wondering if anyone has any ideas why something like this could happen, possible causes behind this etc. any guesses? No recent changes in hardware were made, no recent code updates... Thank you.

• Ulimit settings in Oracle 11g on Linux 5

  - by Stuart

  Is there an issue with "Ulimit -Hn" being set too low (at 1024) when (Oracle recommend 65536)? This is for Oracle 64-bit 11g on Linux 5. It is one of the settings that appears to be woefully short of its recommendation. But I am also aware that the database server in question is an Oracle Data Guard Local Standby and should only really have a connection or two from its Primary database server (to ship the redo logs across). The Local Standby database server has 'hung' about 3 times in as many months and then requires a reboot. I do not have access to this server, so rely on others to look at logs etc. The sanity check on kernel params uncovered the low value for "ulimit -Hn". Has anyone ever seen that 'low' value cause a hang or crash?

• httperrors for Linux

  - by Aaron McRuer

  I'm here because the Google has failed to get me what I need. I just recently graduated from university, and I'm working on a website. Back in college I used the school's web server for my projects, and there were a few tools that aided in the process. One was a Linux program/script/executable/prayer to the computing gods called "httperrors". You typed that into bash, and it would pop up any errors that would occur while running the web server. Specifically, if you had errors in your php code, it would tell you what was wrong. I guess it was a debugger of sorts. I can't find any such program's details online. Does this sound familiar to anyone?

• Creating windows links on Linux?

  - by Bart B

  I'm running a SAMBA file store for our Windows users, and I'd like to automatically generate windows LNK files linking to other network shares that the user needs access to. I've done quite a bit of googling and I can't find a way of creating windows links on Linux, or through Perl. I did find a perl module that looked promising in CPAN, but it will only run on Windows unfortunately. If it's not possible to create .LNK files, perhaps there is an alternative solution people can suggest to allow the users to click on a file in one SAMBA store to be linked to a different SAMBA share? Thanks, Bart.

• Ultra Low Latency Linux Distribution or Kernel

  - by Zanler

  I'd like to know if there are any linux distributions that are focused on low latency networking. The area I'm working in is algorithmic trading, and extremely low latency comms between machines is a must. The current h/w we're using is 10g ethernet, we're looking into things like infiniband RDMA and Voltaire VMA I've googled around, and have only been able to find tidbtits of kernel patches, command line options and hardware suggestions. I'm looking for a complete solution, specially built kernel, kernel bypass features, essentially all the goodies rolled up into one package - does such a thing even exist? I ask as a lot of this stuff seems to be a black art, people keep secret what they know works etc.

• Software RAID 10 on Linux

  - by vpetersson

  For a long time, I've been thinking about switching to RAID 10 on a few servers. Now that Ubuntu 10.04 LTS is live, it's time for an upgrade. The servers I'm using are HP Proliant ML115 (very good value). It has four internal 3.5" slots. I'm currently using one drive for the system and a RAID5 array (software) for the remaining three disks. The problem is that this creates a single-point-of-failure on the boot drive. Hence I'd like to switch to a RAID10 array, as it would give me both better I/O performance and more reliability. The problem is only that good controller cards that supports RAID10 (such as 3Ware) cost almost as much as the server itself. Moreover software-RAID10 does not seem to work very well with Grub. What is your advice? Should I just keep running RAID5? Have anyone been able to successfully install a software RAID10 without boot issues?

• Linux server remounted to read-only

  - by Eustahije

  I have tried to find anwser on SF, but no luck. Nothing worked. (and I have just basic knowledge of linux systems - I'm more developer) Hour ago I noticed that database is not reacting anymore. From some reason system went to readonly mode. Complete server is now, ofc, unavailable. Server is VPS in Dutch company, and have no idea what I can do with it now to unlock it. Every suggestion would be more then appriciated. I tried to save as much of database as possible but there are 20G of images, that would be hard to backup, but I can do that also, if that is something that is smart to do.

• Linux: find thin server running on port 80 and kill it

  - by Andrew

  On my Linux server I ran: sudo thin start -p 80 -d Now I'd like to restart the sever. The trouble is, I can't seem to get the old process to kill it. I tried: netstat -anp But what I see on port 80 is this: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN - So, it didn't give me a PID to kill... I tried pgrep -l thin but that gave me nothing. Meanwhile pgrep -l ruby gives me like 6 processes running. I don't really understand why multiple ruby threads would be running, or which one I need to kill... How do I kill / restart the thin daemon?

• Linux policy routing - packets not coming back

  - by Bugsik

  i am trying to set up policy routing on my home server. My network looks like this: Host routed VPN gateway Internet link through VPN 192.168.0.35/24 ---> 192.168.0.5/24 ---> 192.168.0.1 DSL router 10.200.2.235/22 .... .... 10.200.0.1 VPN server The traffic from 192.168.0.32/27 should be and is routed through VPN. I wanted to define some routing policies to route some traffic from 192.168.0.5 through VPN as well - for start - from user with uid 2000. Policy routing is done using iptables mark target and ip rule fwmark. The problem: When connecting using user 2000 from 192.168.0.5 tcpdump shows outgoing packets, but nothing comes back. Traffic from 192.168.0.35 works fine (here I am not using fwmark but src policy). Here is my VPN gateway setup: # uname -a Linux placebo 3.2.0-34-generic #53-Ubuntu SMP Thu Nov 15 10:49:02 UTC 2012 i686 i686 i386 GNU/Linux # iptables -V iptables v1.4.12 # ip -V ip utility, iproute2-ss111117 IPtables rules (all policies in table filter are ACCEPT) # iptables -t mangle -nvL Chain PREROUTING (policy ACCEPT 770K packets, 314M bytes) pkts bytes target prot opt in out source destination Chain INPUT (policy ACCEPT 767K packets, 312M bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 5520 packets, 1920K bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 782K packets, 901M bytes) pkts bytes target prot opt in out source destination 74 4707 MARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner UID match 2000 MARK set 0x3 Chain POSTROUTING (policy ACCEPT 788K packets, 903M bytes) pkts bytes target prot opt in out source destination # iptables -t nat -nvL Chain PREROUTING (policy ACCEPT 996 packets, 51172 bytes) pkts bytes target prot opt in out source destination Chain INPUT (policy ACCEPT 7 packets, 432 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 1364 packets, 112K bytes) pkts bytes target prot opt in out source destination Chain POSTROUTING (policy ACCEPT 2302 packets, 160K bytes) pkts bytes target prot opt in out source destination 119 7588 MASQUERADE all -- * vpn 0.0.0.0/0 0.0.0.0/0 Routing: # ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master lan state UNKNOWN qlen 1000 link/ether 00:40:63:f9:c3:8f brd ff:ff:ff:ff:ff:ff valid_lft forever preferred_lft forever 3: lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 00:40:63:f9:c3:8f brd ff:ff:ff:ff:ff:ff inet 192.168.0.5/24 brd 192.168.0.255 scope global lan inet6 fe80::240:63ff:fef9:c38f/64 scope link valid_lft forever preferred_lft forever 4: vpn: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 100 link/none inet 10.200.2.235/22 brd 10.200.3.255 scope global vpn # ip rule show 0: from all lookup local 32764: from all fwmark 0x3 lookup VPN 32765: from 192.168.0.32/27 lookup VPN 32766: from all lookup main 32767: from all lookup default # ip route show table VPN default via 10.200.0.1 dev vpn 10.200.0.0/22 dev vpn proto kernel scope link src 10.200.2.235 192.168.0.0/24 dev lan proto kernel scope link src 192.168.0.5 # ip route show default via 192.168.0.1 dev lan metric 100 10.200.0.0/22 dev vpn proto kernel scope link src 10.200.2.235 192.168.0.0/24 dev lan proto kernel scope link src 192.168.0.5 TCP dump showing no traffic coming back when connection is made from 192.168.0.5 user 2000 # tcpdump -i vpn tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vpn, link-type RAW (Raw IP), capture size 65535 bytes ### Traffic from user 2000 on 192.168.0.5 ### 10:19:05.629985 IP 10.200.2.235.37291 > 10.100-78-194.akamai.com.http: Flags [S], seq 2868799562, win 14600, options [mss 1460,sackOK,TS val 6887764 ecr 0,nop,wscale 4], length 0 10:19:21.678001 IP 10.200.2.235.37291 > 10.100-78-194.akamai.com.http: Flags [S], seq 2868799562, win 14600, options [mss 1460,sackOK,TS val 6891776 ecr 0,nop,wscale 4], length 0 ### Traffic from 192.168.0.35 ### 10:23:12.066174 IP 10.200.2.235.49247 > 10.100-78-194.akamai.com.http: Flags [S], seq 2294159276, win 65535, options [mss 1460,nop,wscale 4,nop,nop,TS val 557451322 ecr 0,sackOK,eol], length 0 10:23:12.265640 IP 10.100-78-194.akamai.com.http > 10.200.2.235.49247: Flags [S.], seq 2521908813, ack 2294159277, win 14480, options [mss 1367,sackOK,TS val 388565772 ecr 557451322,nop,wscale 1], length 0 10:23:12.276573 IP 10.200.2.235.49247 > 10.100-78-194.akamai.com.http: Flags [.], ack 1, win 8214, options [nop,nop,TS val 557451534 ecr 388565772], length 0 10:23:12.293030 IP 10.200.2.235.49247 > 10.100-78-194.akamai.com.http: Flags [P.], seq 1:480, ack 1, win 8214, options [nop,nop,TS val 557451552 ecr 388565772], length 479 10:23:12.574773 IP 10.100-78-194.akamai.com.http > 10.200.2.235.49247: Flags [.], ack 480, win 7776, options [nop,nop,TS val 388566081 ecr 557451552], length 0

• Advice wanted on advanced Linux certification/courses including RHCA

  - by nitins

  I have been working in Linux administration for 2.5 years. I would like to have a certification in this. Yes RHCE is an option. I think I already know most of the RHCE stuff. But I would like to have something advanced. I am ready for a full time course as I am not getting the exposure in my current company. Please give me suggestions about training/courses. I have found a course called RHCA(Architect). Is this a good course?
